Referring to fig. 2, a first embodiment of a driver coma handling method of the present invention provides a driver coma handling method including:
step S10, detecting the action of the driver in real time;
the execution subject of this embodiment is an automobile, and the devices and apparatuses involved in the method may be installed on the automobile or connected to the automobile through network connection, physical connection, or other communication methods, which is not limited in this embodiment.
The real-time detection can be realized by capturing one or more information such as the appearance, the movement of body parts, the released energy and the like of a driver in one or more combination modes of installing a camera in front of the driver or other places capable of completely recording the actions of the driver, setting a sensor, setting an infrared imaging device and the like, and analyzing the captured data to obtain the actions of the driver.
The motion may be a bodily motion, such as: body rest, body vibration, etc., or individual movements of various parts of the body, such as: lifting, drooping, left-right moving, bending, etc. of the head, hands, arms, legs, steps, trunk, etc.
The method for detecting the actions of different body parts of the driver can be that the body parts of the driver are identified through one or more modes of image characteristics, positions, positioning or sensors, and then the actions of the different parts are analyzed according to one or more modes of image characteristic matching, action identification models, position changes or energy changes; it is also possible to analyze the motion and the location where the motion occurs by providing one or more detectors (e.g., infrared sensor, laser detector, light sensor, etc.) at the location where the motion is predicted to pass, and analyzing the motion and the location where the motion occurs based on the detected parameters (e.g., time, sequence, etc.). For example: acquiring body contour information of a driver by an infrared imaging technology, matching models to determine different parts of the body, acquiring movement information of different parts to match the models to determine actions of different parts; a hand wearing pressure sensor detects hand movement; acquiring a body feature matching feature model of a driver through a camera to determine body parts, and judging the action of each part through matching an action recognition model by shooting videos or continuously shooting; the infrared detection of the large heat energy emitted by the feet judges that the feet move; mounting a sensor on a steering wheel to monitor whether the hands of a driver leave the steering wheel; light sensors are arranged on two sides of the neck, the outer side of the waist, the outer side of the shoulder and the like to detect whether the driver has head and/or hands drooping and the like due to coma.
The real-time detection can be always kept in an on state, a switch is set to be manually turned on or the on condition (such as ignition, the vehicle speed reaches a preset value, a driver seat is provided with a pressure sensor and the like) is set to trigger the on.
Specifically, before the step of detecting the driver's action in real time, the method further includes:
judging whether the driving state of the vehicle is in driving;
whether the vehicle is in the running state or not is judged according to one or more of the information of the vehicle speed, the positioning change and the like, and whether the vehicle keeps the running state or not can be judged according to one or more of the information of the parking time length, the flameout and the like.
When the driving state of the vehicle is in driving, the action of the driver is detected in real time.
When the driving state of the vehicle is in driving, starting real-time detection equipment to detect the action of a driver in real time; and when the running state of the vehicle is not running, turning off the real-time detection equipment. The real-time detection is started only during driving, so that the accuracy of the coma state judgment of the driver can be improved, the misjudgment of the coma of the driver is reduced, the energy can be saved, and the service life of the equipment is prolonged.
Step S20, when the head and/or hand droop action of the driver is detected and the duration of the droop action is longer than the preset duration, determining that the body state of the driver is in a coma state;
when a drooping motion of the driver's head and/or hands is detected, the duration of the motion is determined, which is the time from the start of one motion to the start of the next motion, so the drooping motion duration includes the sum of the displacement time of the drooping motion and the rest time after the displacement of the drooping motion is completed and before the next motion is started, for example: the hand droop displacement time is 1 second, the hand is not moved after the hand droop, after the hand droop is stopped for 10 seconds, the hand moves horizontally, and the duration of the droop action at the moment is 11 seconds.
And when the duration of the droop action is longer than the preset duration, determining that the body state of the driver is in a coma state.
Step S30, changing the vehicle running mode into the unmanned driving mode;
when it is determined that the driver enters the coma state, the vehicle transmits a request for switching the unmanned driving mode, and the server changes the driving state of the vehicle in response to the request.
The unmanned driving mode is to sense the surroundings of the vehicle using an on-vehicle sensor and to control the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained by the sensing, thereby enabling the vehicle to safely and reliably travel on the road.
In the unmanned driving mode, the vehicle may continue to be controlled to drive to the destination, continue to run on the road, stop at the side, and the like according to the navigation information connected to the vehicle, which is not limited in this embodiment.
The unmanned mode can also comprise safety warning measures, such as turning on a lamp, whistling and the like, for prompting surrounding vehicles and pedestrians that the vehicle is in the unmanned mode.
Optionally, after the step of changing the vehicle driving mode to the unmanned driving mode, the method further includes:
and detecting road surface environment information, and controlling the vehicle to stop at the side based on the environment information.
Through equipment such as camera, radar, sensor, navigation, detect road surface environmental information, control vehicle is under unmanned driving mode, seeks suitable position according to road surface environmental information and leans on the limit to park to wait for the rescue.
The road surface environment information is a road surface environment condition around the vehicle, such as: traffic congestion, whether there are obstacles or pedestrians in front, current location, lanes, traffic light areas, pedestrian crossing areas, etc.
The position suitable for parking by side is determined by detecting the road surface environment information, so that the condition that normal traffic is not influenced by traffic rules can be guaranteed not to be violated, vehicles and pedestrians can be well avoided to avoid traffic accidents, the vehicle is controlled to park by side in time, the influence on traffic can be reduced to the minimum extent, and the following rescuers can be enabled to better determine the position of the vehicle to find out a unconscious driver to implement rescue quickly.
Optionally, after the step of changing the vehicle driving mode to the unmanned driving mode, the method further includes:
all lights are turned on to alert other vehicles.
When the driver is determined to be in a coma state, after the vehicle is changed into an unmanned driving mode, the control of the vehicles such as the speed and the direction of the vehicle is different from the normal driving, if the speed of the vehicle is low, the normal driving of other vehicles can be influenced, all the lamps are turned on to remind the warning of surrounding vehicles, the abnormal condition of the vehicle occurs, the vehicle is in an abnormal driving state, the surrounding vehicles can adjust the driving route in time after seeing the warning lamps, the vehicle keeps a proper distance with the abnormal vehicle or drives around the road, the traffic accident can be effectively avoided, and the life safety of the vehicle and personnel is ensured.
