Description

  The present invention relates to a vehicle occupant rescue assistance system that controls a vehicle according to the health state of the vehicle occupant.

  Conventionally, as one of the additional functions of a vehicle, a function for evaluating and managing the health condition of an occupant who rides on a vehicle on a daily basis is being expanded. In other words, vital information that serves as an index of the occupant's health condition is detected by a vital sensor, and the occupant's health condition is determined based on the vital information. Such a health management function can be used for health management of an occupant with a high boarding frequency, such as a car commuter or a business driver.

  In recent years, it has been studied to make biometric information collected by a vehicle available not only to the occupant but also outside the vehicle. For example, a system for transmitting biological information to a server device, a home computer, etc. via a mobile phone communication network or the Internet has been proposed. It has also been proposed to transmit biological information to a hospital or emergency center when the occupant's health condition deteriorates (see Patent Documents 1 and 2). Such a linkage system between the vehicle and the outside of the vehicle is considered to be useful for objective occupant health diagnosis and emergency response in case of poor physical condition.

JP 2010-057664 A JP 2012-024481

  For the emergency response at the time of poor physical condition as described above, first-aid treatment that fights for a moment may be required. For example, when there is a suspicion of sunstroke or heat stroke, it is desirable to keep a rest in a cool environment. In order to maintain a good breathing function and circulation function, it is desirable to release the restraint of the seat belt and tilt the seat back backward (to make it easier) after stopping the vehicle safely. In some cases. If appropriate first aid is taken, the lifesaving effect of the occupant can be improved, and the subsequent health status (post recovery) can be improved.

  However, the content of appropriate first aid varies in various ways depending on the state of passengers and environmental conditions. For this reason, it is difficult not only to independently determine what the occupant should do, but also to implement control based on mechanical determination. Conventional health management systems are not sufficiently compatible with such first-aid treatment, and there is a possibility that the health condition of the occupant will be reduced.

  This case has been devised in view of the problems as described above, and an object thereof is to provide a vehicle occupant rescue assistance system that can suppress a decrease in the health state of the occupant. It should be noted that the present invention is not limited to this purpose, and is an operational effect that is derived from each configuration shown in “Mode for Carrying Out the Invention” to be described later.

  A vehicle occupant rescue assistance system as an embodiment will be described with reference to the drawings. The embodiment described below is merely an example, and there is no intention of excluding various modifications and technical applications that are not explicitly described in the following embodiment. Each configuration of the present embodiment can be implemented with various modifications without departing from the spirit of the present embodiment, and can be selected or combined as necessary.

[1. vehicle]
FIG. 1 is a diagram schematically illustrating the overall configuration of a vehicle occupant rescue assistance system according to the present embodiment. In this system, the vehicle 30 and the medical institution 50 are connected via the network 40. The network 40 is, for example, a wireless communication network for mobile phones, a wired or wireless communication network formed using the Internet, an inter-vehicle communication network, and the like. The medical institution 50 here is assumed to be a hospital where passengers of the vehicle 30 are hooked, a nearest clinic, an emergency hospital, or the like.

  Two types of electronic control units (Electronic Control Units, ECUs) are mounted on the vehicle 30. The first electronic control unit is an occupant rescue auxiliary ECU 10, which has a function of evaluating and managing the occupant's health state and a function of controlling and managing information exchanged with the medical institution 50 of the vehicle 30. The second electronic control unit is a vehicle compartment environment ECU 20 having a function of managing air conditioning environment control, seating posture control, and lighting control. These occupant rescue auxiliary ECU 10 and vehicle interior environment ECU 20 are connected to a communication line of an in-vehicle network mounted on the vehicle 30 and can communicate with each other.

  The air conditioning environment control described above is control for adjusting the air conditioning environment (temperature, humidity, ventilation state, etc.) in the passenger compartment. The seating posture control is control for adjusting a passenger's seat environment (sitting posture), and the lighting control is control for adjusting the lighting environment (illuminance) in the passenger compartment. In principle, the vehicle compartment environment ECU 20 performs air-conditioning environment control, seating posture control, and lighting control in accordance with an occupant input operation. On the other hand, when the occupant is in poor physical condition, these controls can be performed based on the determination in the medical institution 50 without depending on the occupant's input operation. Specific control contents of the occupant rescue auxiliary ECU 10 and the vehicle interior environment ECU 20 will be described later.

  The passenger rescue assistance ECU 10 and the passenger compartment environment ECU 20 are provided at arbitrary positions of the vehicle 30. Further, in the vehicle interior of the vehicle 30, as a device connected to the passenger rescue auxiliary ECU 10 and the vehicle interior environment ECU 20, a vital sensor 2, a collision sensor 3, a camera 4, a speaker 5, a microphone 6, a power slide seat 8, An air conditioner 9 and a lighting device 17 are provided. Further, the radio communication antenna 7 is provided on the outer surface of the vehicle 30.

  The vital sensor 2 (biological information sensor) is a sensor that acquires biological information of an occupant seated on the seat 1. The biological information is information that serves as an index of the health condition of the occupant, and is information such as pulse, respiration, body temperature, blood pressure, and weight, for example. Specific examples of the vital sensor 2 include a pulse sensor and a Doppler sensor. The pulse sensor detects the pulse based on the pulsation of the hand holding the steering wheel, the skin pressure change, the potential change, or the like. The Doppler sensor detects periodic body movements associated with pulsations and breathing movements based on sound waves and reflected waves of radio waves emitted toward the occupant. A vital sensor 2 in FIG. 1 is a Doppler sensor (radio wave sensor) built under the cushion of the seat 1, and based on the reflected wave of the radio wave irradiated to the occupant's buttocks, information on the occupant's heart rate is obtained. To detect. The biological information detected here is transmitted to the occupant rescue auxiliary ECU 10.

  The collision sensor 3 is a sensor for acquiring a physical quantity generated by a collision of the vehicle 30. A collision sensor 3 in FIG. 1 is an acceleration sensor that detects longitudinal acceleration (deceleration) generated in the vehicle body. The collision of the vehicle 30 can be determined, for example, when the absolute value of the acceleration is equal to or greater than a predetermined value. Specific examples of the other collision sensor 3 include a pressure sensor that detects a pressure fluctuation caused by a deformation of the vehicle body due to a collision, a radar sensor that detects a distance from a preceding vehicle, and the like. Information on the vehicle collision detected here is transmitted to the occupant rescue auxiliary ECU 10.

The camera 4 captures the interior of the vehicle 30 and the passenger as video images. This video information is transmitted to the outside of the vehicle 30 via the occupant rescue assist ECU 10, and is used for diagnosing the occupant's health condition and grasping the state of the passenger compartment in the medical institution 50.
The speaker 5 and the microphone 6 are voice call devices for establishing a voice call between the outside of the vehicle 30 and an occupant. The microphone 6 collects the sound in the passenger compartment of the vehicle 30 and the sound of the occupant and outputs the sound as sound information to the occupant rescue auxiliary ECU 10. This audio information is also transmitted to the outside of the vehicle 30 via the occupant rescue auxiliary ECU 10 and is used for diagnosing the occupant's health condition and grasping the state of the passenger compartment in the medical institution 50 in the same manner as the above video information. The speaker 5 is an acoustic device for transmitting a voice of a medical person to the occupant. For example, the speaker 5 is used for calling from the medical person to the occupant, a question regarding a health condition, confirmation of a subjective symptom, an inquiry, and the like. .

  The wireless communication antenna 7 is a communication device (antenna) for performing wireless communication between the occupant rescue auxiliary ECU 10 and the outside of the vehicle 30 (medical institution 50). The radio communication antenna 7 transmits a signal from the occupant rescue auxiliary ECU 10 as a radio transmission wave to the medical institution 50, receives a signal transmitted from the medical institution 50 as a radio reception wave, and receives the information as the occupant rescue auxiliary ECU 10. To communicate.

  The power slide seat 8 (environment control device, seating posture control device) is a drive mechanism for adjusting the seating environment of the seat 1 mounted on the vehicle 30 (that is, the posture of the seat 1 and the seating posture of the occupant). It is an automatic adjustment device provided with (an electric actuator, a hydraulic actuator, etc.). What is adjusted by the power slide seat 8 is, for example, the longitudinal position of the seat 1, the vertical position of the seat 1, the inclination angle of the seat back, the height of the seat cushion, the hardness (elasticity) of the seat cushion, and the like. .

  The control amounts of these parameters are managed by the passenger compartment environment ECU 20. For example, when an occupant operates an operation switch (for example, a switch or preset switch for increasing or decreasing each parameter) provided on the instrument panel, the operation information is transmitted to the vehicle compartment environment ECU 20. The vehicle interior environment ECU 20 sets the operation amount of the drive mechanism according to the operation information, and outputs a drive signal to the drive mechanism. Thereby, the posture of the seat 1 is adjusted so that a desired sitting posture is obtained.

  The air conditioner 9 (environment control device, air conditioning environment control device) adjusts the air conditioning environment in the passenger compartment of the vehicle 30. The air conditioner 9 includes a heater, an evaporator, a fan, an inside air circulation duct, an outside air introduction duct, and the like. The air conditioner 9 is used to adjust the temperature, humidity, ventilation (oxygen concentration), etc. in the passenger compartment according to the operation of the passenger. Further, the control amounts of these parameters are managed by the vehicle compartment environment ECU 20. For example, when an occupant operates an operation switch (for example, an air conditioning switch, a temperature adjustment lever, an air volume adjustment lever, etc.) provided on the instrument panel, the operation information is transmitted to the vehicle compartment environment ECU 20. The vehicle interior environment ECU 20 sets operation amounts of heaters, evaporators, fans, and the like according to the operation information, and outputs drive signals to each of these. As a result, the air conditioner 9 is controlled so that the air conditioning environment in the passenger compartment is in a desired state.

  The illuminating device 17 (environment control device) is a variable illuminance light mounted in the passenger compartment to illuminate an occupant. The lighting state of the lighting device 17 can be switched by a manual switch operation, and is automatically switched in conjunction with the opening / closing state of the door of the vehicle 30 and the operating state of the camera 4. Moreover, the brightness of the illuminating device 17 can also be changed by a switch operation by a passenger. An existing room light may be used as the lighting device 17, but when the room light is arranged at the center in the vehicle front-rear direction on the ceiling surface, the lighting device 17 is provided near the front end of the ceiling surface. It is preferable to provide them separately. Backlight is prevented by irradiating light from the front of the occupant, and the occupant's face color, facial expression, upper body posture, and the like in the image of the camera 4 are easily visible.

  The power slide seat 8, the air conditioner device 9, and the lighting device 17 of the present embodiment are controlled based on not only the passenger's input operation but also a remote operation command from the medical institution 50. That is, when the occupant rescue auxiliary ECU 10 receives a remote operation command, the passenger compartment environment ECU 20 controls the operating states of the power slide seat 8, the air conditioner device 9, and the lighting device 17 based on the remote operation command. In other words, medical personnel of the medical institution 50 can mainly adjust the posture of the seat 1, the temperature, humidity, illuminance, etc. of the passenger compartment. However, this is limited to the case where the occupant's health condition is not excellent, and the medical institution 50 determines that the occupant's physical and mental burdens are appropriate. Therefore, the power slide sheet 8, the air conditioner device 9, and the lighting device 17 are not remotely operated unconditionally, but are remotely operated based on the judgment of the medical institution 50.

  Hereinafter, the occupant rescue auxiliary ECU 10 and the vehicle compartment environment ECU 20 are also simply expressed as ECUs 10 and 20. Each of the ECUs 10 and 20 is formed as an electronic device (computer) in which a processor device and a memory device are integrated. Each ECU 10, 20 includes, for example, a central processing unit, a memory device, an interface device, etc., which are connected via an internal bus. These ECUs 10 and 20 operate by receiving power supply from an arbitrary power source (for example, an in-vehicle battery or a button battery).

  The central processing unit described above is a processor including a control unit (control circuit), an arithmetic unit (arithmetic circuit), a cache memory (register group), and the like. The memory device includes a short-term memory element that temporarily stores a program and working data, and a long-term memory element that stores data and programs held for a long time. The former is, for example, ROM (Read Only Memory) and RAM (Random Access Memory), and the latter is non-volatile memory, such as flash memory or EEPROM (Electrically Erasable Programmable Read-Only Memory).

  The interface device controls input / output (I / O) between the ECUs 10 and 20 and the outside. Each of the ECUs 10 and 20 is connected to, for example, an in-vehicle network via an interface device, or directly connected to the various devices 2 to 9 and 17. Note that other electronic control devices (for example, an engine ECU, a motor ECU, a vehicle body control ECU, a battery ECU, etc.), a liquid crystal monitor as an output device, and the like are connected to the in-vehicle network.

[2. Medical institution]
As shown in FIG. 2, a medical institution server 51 is provided in the medical institution 50. The medical institution server 51 is a large-sized computer having a processor device, a memory device, a storage device, and the like, and is provided so as to be able to communicate with the occupant rescue auxiliary ECU 10 of the vehicle 30 via the network 40. The medical institution server 51 has a function of providing information transmitted from the occupant rescue assist ECU 10 to medical personnel (doctors, nurses, paramedics, etc.), a power slide seat 8 of the vehicle 30, an air conditioner 9, and lighting. It also has a function of outputting a remote operation command for remotely operating the device 17. Since the medical institution server 51 and the ECUs 10 and 20 are both computers and the basic hardware configuration is the same, description of the hardware configuration of the medical institution server 51 is omitted.

  Connected to the medical institution server 51 are a display 52, a speaker 53, a microphone 54, an operation switch 55, and a wireless communication antenna 56. The display 52 is a display device that displays an image captured by the camera 4 of the vehicle 30. The wireless communication antenna 56 is a communication device (antenna) similar to the wireless communication antenna 7 of the vehicle 30. If the medical institution server 51 is connected to the network 40 by wire, the wireless communication antenna 56 can be omitted.

  The speaker 53 and the microphone 54 are voice communication devices used as a pair with the speaker 5 and the microphone 6 of the vehicle 30. That is, the sound input to the microphone 6 of the vehicle 30 is output from the speaker 53 of the medical institution 50, and the sound input to the microphone 54 of the medical institution 50 is output from the speaker 5 of the vehicle 30. Thereby, a two-way voice call is established between the occupant of the vehicle 30 and the medical personnel of the medical institution 50.

  The operation switch 55 is an operation switch similar to that provided on the instrument panel of the vehicle 30, and is an input device for remotely operating the power slide seat 8, the air conditioner device 9, and the lighting device 17. Specifically, it corresponds to a switch, preset switch, air conditioning switch, temperature adjustment lever, air volume adjustment lever, lighting device 17 lighting switch, brightness adjustment lever, etc. that increase or decrease each parameter that can be adjusted by the power slide sheet 8. Switches are provided. These input operations to the operation switch 55 are valid only while the biological information regarding the occupant with poor physical condition is transmitted from the vehicle 30 side. Instead of the operation switch 55, a control configuration that realizes remote operation using an input operation with a keyboard or a mouse connected to the medical institution server 51 may be employed.

[3. Processing content]
Processing contents of control in the ECUs 10 and 20 and the medical institution server 51 will be described with reference to FIG. The processing content in each ECU 10, 20 and medical institution server 51 is recorded in each memory device (long-term storage element) as an application program, for example, or is recorded on a removable medium that can be read by a computer. The application program is expanded and executed in the memory space of the memory device (short-term storage element). The program executed by the occupant rescue auxiliary ECU 10 includes an occupant state estimation unit 11, a collision detection unit 12, and a remote operation control unit 13.

  The occupant state estimation unit 11 (estimation unit) estimates whether or not the occupant is in poor physical condition based on the biological information acquired by the vital sensor 2. The function to evaluate and manage the occupant's health is realized here. For example, with respect to the heart rate per unit time of the occupant, an average value within a past predetermined time is calculated, and a predetermined fluctuation range centered on the average value is set. And when the heart rate acquired with the vital sensor 2 changes out of the fluctuation | variation range, it estimates that a passenger | crew is in poor physical condition. Note that specific conditions for determining whether or not the patient is in poor physical condition can be arbitrarily set, and known determination conditions may be used. Information on the health state of the passenger estimated here is transmitted to the remote operation control unit 13.

  The collision detection unit 12 detects a collision of the vehicle 30. Here, the presence or absence of a collision is determined based on the physical quantity acquired by the collision sensor 3. For example, when the absolute value of the acceleration obtained by the collision sensor 3 is a predetermined value or more, it is determined that the vehicle 30 has collided with some object. Note that the presence or absence of a collision can also be determined using (or using in combination) information other than the information acquired by the collision sensor 3. For example, based on an operation signal of an airbag device installed in the vehicle 30, an emergency stop signal output from another electronic control device (for example, an engine ECU, a motor ECU, a vehicle body control ECU, a battery ECU, etc.) The presence or absence of a collision may be determined. The information regarding the presence or absence of the collision determined here is transmitted to the remote operation control unit 13.

  The remote operation control unit 13 controls and manages the communication contents between the vehicle 30 and the medical institution 50 and controls the remote operation from the medical institution 50. These controls performed by the remote operation control unit 13 are also referred to as remote operation control. Inside the remote operation control unit 13, a transmission / reception unit 14, an external control unit 15, and a system stop unit 16 are provided.

  The transmitting / receiving unit 14 transmits at least the biological information acquired by the vital sensor 2 to the medical institution 50 and receives a remote operation command from the medical institution 50. Transmission / reception of these pieces of information is realized by wireless communication via the wireless communication antenna 7. Further, the condition for transmitting information to the medical institution 50 is “the occupant state estimation unit 11 has estimated that the occupant is in poor physical condition” or “the collision detection unit 12 has detected a collision of the vehicle 30. Is. When a collision of the vehicle 30 is detected, an additional condition may be that “the vehicle 30 has become stationary after the collision” in order to start transmitting information after the vehicle 30 has stopped safely. .

  The transmission / reception unit 14 of the present embodiment has a function of turning on the main power of the camera 4, the speaker 5, and the microphone 6 when the above conditions are satisfied. In addition to the biological information, video information captured by the camera 4, audio information collected by the microphone 6, information on the operating state of the air conditioner 9 (target room temperature, fan speed, etc.), power slide sheet 8 It has a function of transmitting information on the operating state (front-rear direction position, vertical position, inclination angle, etc.) to the medical institution 50. Further, the transmission / reception unit 14 of the present embodiment has a function of transmitting information related to the air-conditioning environment such as the temperature, humidity, and ventilation state of the passenger compartment to the medical institution 50. As a result, for example, the medical institution 50 grasps in real time the situation in which an unwell occupant is placed, the actual complexion, consciousness state, sitting posture, etc., and the accuracy of diagnosing the occupant's health condition and grasping the state of the passenger compartment is improved. improves.

  The above “remote operation command from the medical institution 50” is a control signal for medical personnel of the medical institution 50 to remotely operate the power slide seat 8, the air conditioner device 9 and the lighting device 17 of the vehicle 30. The remote operation command includes, for example, information on the target temperature, target humidity, target ventilation amount, etc. of the air conditioner 9, information on the target position, target height, target inclination, etc. of the seat 1 by the power slide seat 8, and the lighting device 17 illuminance information are included. Further, the determination of whether or not to perform remote operation and the content of the remote operation command by remote operation are left to the judgment of medical personnel. For example, when a medical person in the medical institution 50 operates the operation switch 55, the operation information is transmitted to the medical institution server 51, and a remote operation command corresponding to the operation information is output from the medical institution server 51. The condition for outputting the remote operation command from the medical institution server 51 is that the biological information is input from the vehicle 30 side and that the medical staff operates the operation switch 55.

  When receiving a remote operation command from the medical institution 50, the external control unit 15 controls the operating states of the power slide seat 8, the air conditioner device 9, and the lighting device 17 based on the remote operation command. Here, the control contents before receiving the remote operation command are overwritten by the remote operation command, and the operation state based on the remote operation command is set. That is, the control based on the remote operation command from the medical institution 50 is preferentially performed as compared with the control before receiving the remote operation command.

  For example, when it is diagnosed that the occupant's body temperature is decreasing, a remote operation command for increasing the set temperature of the air conditioner 9 is input from the medical institution 50 to the occupant rescue auxiliary ECU 10. In response to this, the external control unit 15 outputs a control signal to the passenger compartment environment ECU 20 to raise the set temperature of the air conditioner 9. On the other hand, when there is a suspicion of sunstroke or heat stroke, a remote operation command for lowering the set temperature of the air conditioner 9 is input from the medical institution 50 to the occupant rescue auxiliary ECU 10. In response to this, the external control unit 15 causes the vehicle compartment environment ECU 20 to perform control to lower the set temperature of the air conditioner device 9. The same applies to the power slide seat 8 and the lighting device 17, and the tension of the seat belt, the inclination angle of the seat back, the illuminance in the passenger compartment, and the like are appropriately controlled according to the diagnosis result in the medical institution 50.

  The system stop unit 16 performs control to stop information transmission from the transmission / reception unit 14 by remote operation from the medical institution 50. The system stop unit 16 according to the present embodiment not only simply stops transmission of information, but also performs control to turn off the main power of the power slide sheet 8, the air conditioner device 9, and the lighting device 17. Preferably, the system stop unit 16 controls the main power supply of the occupant rescue auxiliary ECU 10 and the passenger compartment environment ECU 20 to be turned off. Alternatively, the main power supply of the vehicle 30 is controlled to be turned off.

  For example, there is a case where the diagnosis of the medical institution 50 is finished and the occupant's biological information, video information, and the like are not necessary. On the other hand, if the occupant is unconscious at this time, the operation of the occupant rescue auxiliary ECU 10 cannot be stopped, and the video information in the vehicle compartment continues to be transmitted to the medical institution 50. Further, when there is no passenger in the vehicle 30, after the occupant is rescued by the rescue team and transported to the hospital, the vehicle 30 is left as it is. In this case, although no one is on board the vehicle 30, the video image captured by the camera 4 and the audio information in the passenger compartment are continuously transmitted. The system stop unit 16 has a function of stopping the transmission of biological information by the transmission / reception unit 14 as described above.

  Further, it is assumed that the medical personnel of the medical institution 50 remotely operates the operating states of the air conditioner device 9 and the lighting device 17 as emergency measures for the occupant. Thereafter, it is conceivable that the diagnosis of the occupant is completed and the temperature and humidity in the passenger compartment are appropriately controlled and it is determined that there is no need to continue operating the air conditioner device 9 and the lighting device 17. At this time, if the occupant loses consciousness, the operation of turning off the main power supply of the air conditioner 9 and the lighting device 17 cannot be performed, and these continue to operate. The system stop unit 16 has a function of stopping the operations of the power slide sheet 8, the air conditioner device 9, and the lighting device 17.

  Note that a function for remotely cutting off the power supply to the occupant rescue auxiliary ECU 10 and the vehicle compartment environment ECU 20 may be implemented in the system stop unit 16. For example, when a system stop command is received from the medical institution 50, control is performed to turn off the power to the occupant rescue auxiliary ECU 10 and the vehicle compartment environment ECU 20 based on the system stop command. Alternatively, the main power supply of the vehicle 30 is turned off and the entire system is stopped. As a result, not only the air conditioner device 9 and the lighting device 17 but also the transmission of the vehicle interior image can be stopped.

The cabin environment ECU 20 is provided with an air conditioning environment control unit 21, a seating posture control unit 22, and a lighting control unit 23.
The air conditioning environment control unit 21 performs the above air conditioning environment control. In addition to the air conditioner device 9, the device to be controlled by the air conditioning environment control (air conditioner environment control device) is a power window device, a door lock device, a power gate device (automatic door opening and closing device), a power roof device (automatic roofing). (Opening / closing device) and the like. In principle, the air conditioning environment control unit 21 of the present embodiment controls the operating state of the air conditioner device 9 according to the operation of the operation switch by the passenger. On the other hand, when the transmission / reception unit 14 receives a remote operation command from the medical institution 50, the control based on the remote operation command is preferentially performed.

  The sitting posture control unit 22 performs the above-described sitting posture control. As a device to be controlled by the seating posture control (sitting posture control device), in addition to the power slide seat 8, a seat belt auto-tensioner device (device for adjusting the tension of the seat belt) and a cushion control device (hardness of the cushion) , A device for adjusting elasticity). In principle, the seating posture control unit 22 controls the operating state of the power slide seat 8 in accordance with the operation of the operation switch by the occupant. On the other hand, when the transmission / reception unit 14 receives a remote operation command from the medical institution 50, the control based on the remote operation command is preferentially performed.

[4. flowchart]
FIG. 3 is an example of a flowchart for determining whether or not the remote operation control by the remote operation control unit 13 is performed. In step A1, the acceleration information acquired by the collision sensor 3 is input to the occupant rescue auxiliary ECU 10, and in step A2, the biological information acquired by the vital sensor 2 is input to the occupant rescue auxiliary ECU 10. In step A3, the occupant state estimation unit 11 estimates the occupant's health state based on the biological information. In step A4, it is determined whether or not the occupant is in poor physical condition. Here, if the occupant is in poor physical condition, the process proceeds to step A5, and control for safely stopping the vehicle 30 is performed. After that, the process proceeds to step A9, where remote operation control is executed.

  If the occupant is not in poor condition in step A4, the process proceeds to step A6. In this step, the collision detection unit 12 determines whether or not the vehicle 30 has collided. Here, when the collision of the vehicle 30 has not occurred, this flow is finished as it is. In this case, control is executed from step A1 in the next calculation cycle. On the other hand, when the collision of the vehicle 30 has occurred, the process proceeds to step A7.

  In step A7, the acceleration information acquired by the collision sensor 3 is input to the occupant rescue auxiliary ECU 10, and in the subsequent step A8, it is determined whether or not the vehicle 30 is stationary. This determination can be made by determining that the absolute value of the acceleration is less than a predetermined value. If the vehicle 30 is stationary, the process proceeds to step A9 and remote control is executed. On the other hand, if the vehicle 30 is not stationary, the motion state of the vehicle 30 may have changed transiently, so the process proceeds to step A7, and acquisition and determination of acceleration information until the vehicle 30 stops. Is repeated.

In the subsequent step B4, it is determined whether or not a remote operation command from the medical institution 50 has been input to the transmission / reception unit 14. If a remote operation command is input, the process proceeds to step B5, and if not, the process proceeds to step B6.

  In step B5, the external control unit 15 controls the power slide sheet 8, the air conditioner 9, and the lighting device 17 based on the remote operation information. As a result, the air conditioner 9 operates according to the diagnosis result in the medical institution 50, and the target temperature is set appropriately. In conjunction with this, the position and the inclination angle of the seat 1 are also adjusted appropriately, and the physical burden and the mental burden on the occupant are reduced. Even if the illuminance of the subject is not appropriate and it is difficult to visually recognize the occupant in the passenger compartment, the illuminance of the illuminating device 17 can be adjusted so that the image can be easily seen on the medical institution 50 side. Therefore, visibility can be easily improved and diagnostic accuracy is improved.

In step B <b> 6, it is determined whether or not a system stop command from the medical institution 50 has been input to the transmission / reception unit 14. If a system stop command is input, the process proceeds to step B7, and if not, the process proceeds to step B1.
In step B7, the system stop unit 16 performs control based on the system stop command. Thereby, the transmission of the biological information in the transmission / reception unit 14 is stopped, and the transmission of the video information, the audio information, and the like in the vehicle interior is also stopped, and the wireless communication is ended. Further, the power slide sheet 8, the air conditioner device 9, and the lighting device 17 are turned off, and the air conditioning control and the lighting control are also ended.
