Description

PRECAUTIONS AND RESTRICTIONS BY Fü fifi üñšå PROMPT We fi ÜLYCKSTELLBUÜ TECHNICAL FIELD This document describes a procedure and a control unit in a vehicle. More specifically, a method and a control unit are to be determined for limiting the driving of the vehicle when an accident is detected in the vehicle.

BACKGROUND When driving a vehicle that transports passengers, for example a bus, a train-carriage, a cable car, a tram, an elevator, an escalator, a conveyor belt, a tracked vehicle, a combat vehicle, an airplane, a boat or the like, there are various packing strategies for passengers. Both standing and seating solutions for passengers often occur in parallel. Furthermore, such a vehicle for passenger transport, or transport device as it may also be called in some cases, is generally arranged to receive different types of passengers, children, the disabled or the elderly. Passengers can also bring a pram, pets, bags, wheelchairs and / or luggage of various kinds. Furthermore, vehicles of the above-mentioned type may be used by persons who, as a result of alcohol and / or drug consumption, have a reduced ability to balance.

Seated, standing and wheelchair-bound passengers are exposed during a given journey to acceleration forces and rotations in the room during transport. In this case, long-distance passengers may find it difficult to keep their balance, for example the elderly, the disabled, children, the drunk, etc. The pram may roll over or overturn, with the risk of personal injury. Wheelchair users should normally be restrained during transport, but there is a risk that a wheelchair may roll or overturn when the vehicle makes a sudden maneuver.

Vehicles of this type, for example city buses, are often characterized by rapid decelerations and level changes at stops with subsequent jump starts, jerky shifts and rapid side accelerations as a result of lane changes.

In addition, in this type of vehicle, it is common for safety equipment to be lacking for passengers, such as seat belts, airbags, curtain curtains and the like. Passengers in a vehicle that transports passengers therefore usually have less protection in the event of a possible traffic incident than other road users, who, for example, are sitting in a car.

In addition, in some of the above-mentioned examples, the vehicle may be completely absent from a driver or other staff present, for example in a cable car, escalator, elevator or a driverless bus or train. In other vehicles of the type mentioned above, drivers and / or other personnel are in another part of the vehicle, such as in a train, a tram or a subway car. In a bus driven by a driver in a conventional way, perhaps especially city traffic, he is often forced to focus on the surrounding traffic situation and is also pressured to follow his timetable, so the driver often has difficulty observing passenger boards, and any damage that has occurred among these.

It is a problem to inform the driver, the surroundings or others that an accident has occurred on board a passenger, for example that a standing passenger has fallen over. The only means that are generally available for the driver to detect an accident in the vehicle is via the rearview mirror in the bus and oral information to the driver from another passenger.

Often the driver's ability to supervise the vehicle's passengers through the rearview mirror is limited. The view to the rear can be obscured by other passengers, or cargo in the aisle, for example. In addition, passenger vehicles are often elongated, which provides additional limited rearward visibility for the driver.

Talking to the driver while driving is often explicitly forbidden in vehicles, such as Icelandic city buses, so it is not certain that any passenger dares to contact the driver when a passenger incident occurs, as a result of misguided righteousness, alternative authority fear. In addition, it is not uncommon for bus drivers to listen to the radio or music while driving, which further increases the risk that an accident occurring for a passenger on board will not be detected by the driver. Furthermore, one can imagine a scenario where a majority of passengers are injured at the same time, for example in connection with a resolute deceleration, the act often lacks a seat belt in buses and many passengers also stand up. Mildly injured but loud passenger can then take all the attention so that a perhaps unconscious passenger remains undetected by the driver. Even if the driver unexpectedly notices an accident on board, the driver is often lacking in readiness to handle the situation that has arisen. Maybe the accident is not perceived as so serious, maybe the driver is in a complicated traffic situation and can not take any action at the moment. There is therefore a great risk that an accident that has occurred will not be remedied by the stool and / or the environment. This danger is of course even greater in vehicles and / or transport devices that have no drivers at all.

The document DE102010054626 shows a monitoring device in a vehicle, comprising a camera or the like which monitors, for example, a door opening in the vehicle. When a passenger is in an area where he risks being pinched or injured when the door is opened / closed, a warning is sent to the driver.

However, what is stated in this document does not solve problems with passengers who fall or are injured elsewhere in the vehicle, or anywhere at all actually. If passengers are injured at the door and fall or stumble out of the picture from the camera, it is probable that the driver does not pay attention to this incident but closes the door and drives on.

It can be stated that much remains to be done to improve passenger safety when transported by vehicle.

SUMMARY It is therefore an object of this invention to be able to solve at least some of the above stated problems and achieve improved detection and action handling of accidents in a vehicle and thus increased passenger safety.

According to a first aspect of the invention, this object is achieved by a computerized procedure in a vehicle, in order to limit the driving of the vehicle when an accident is detected in the vehicle. The method includes detecting an accident in the vehicle, while sensing. Furthermore, the method also comprises informing a person responsible for driving the vehicle of the detected accident. In addition, the method includes investigating whether said person has taken an action when he is informed of the detected accident in the vehicle, wherein said action is included in a list of actions associated with the detected accident. The method also includes limiting the driving of the vehicle, where the limiting of the driving of the vehicle includes a tor-eton tower. sasorn aeeetorationsbeorànsnine hes fordonet; speed limitation of the vehicle: activation to tfarninosbâinkers: active-robbery of taktiša x / Ebrations * E vehicle steering wheel, rnanövrerinosreotaoe and! after driver's seat 'and! after a vehicle external action, such as the emission of a tzteoärest orn red fius vâol nåtöitande trafšktius: attnàšfen nos ooâisrnvstošottetatt stop the vehicle: axfstêštneninc; of the vehicle's engine. According to a second aspect of the invention, this object is achieved by a control unit in a vehicle. The control unit is arranged to limit the driving of the vehicle when an accident is detected in the vehicle. The control unit comprises a processor which is arranged to detect an accident in the vehicle via a sensor. The processor is also arranged to inform a person responsible for driving the vehicle of the detected accident offer. Furthermore, the processor is also arranged to investigate whether said person has taken a single action when he is informed of the detected accident in the vehicle, where said action is included in a list of measures associated with the detected accident. In addition, the processor is also arranged to limit the vehicle's performance. , as the investigation shows that no such action included in the list of actions has been taken.

By detecting an incident or accident in the vehicle, calling the driver's attention to this accident, checking what the driver takes for action as a result of the accident and limiting the vehicle's performance if no or an incorrect action is taken, the risk of an accident in a passenger compartment is reduced. remains undetected and / or undone by the driver of the vehicle. In this way, the accident-affected passenger can receive early intervention-relevant help, which can shorten or perhaps completely eliminate his suffering. Furthermore, a deterioration of the injured person's situation can be avoided, as the vehicle gradually becomes more difficult for the driver to drive.

Other advantages and additional new features will become apparent from the following detailed description.

DETAILED DESCRIPTION Embodiments of the invention comprise a method and a control unit, which can be realized according to any of the examples described below. However, this invention may be practiced in many different forms and should not be construed as limited by the embodiments described herein, which are instead intended to illustrate and illustrate various aspects.

Additional aspects and features of the invention may become apparent from the following detailed description when considered in conjunction with the accompanying figures. However, the figures are to be considered only as examples of various embodiments of the invention and should not be construed as limiting the invention, which is limited only by the appended claims. Furthermore, the figures are not necessarily to scale and are, unless otherwise specifically indicated, intended to conceptually illustrate aspects of the invention.

Figure 1 shows a vehicle 100, adapted for motorized driving in, inter alia, a first direction 105 along a route 110. For example, but not necessarily, the vehicle 100 may be adapted for passenger transport to a greater or lesser extent, so for example a bus, a taxi, a disabled transport vehicle, an animal transport vehicle, a single tram, a metro car, a train compartment, a cable car, an elevator, an escalator, a conveyor belt, a tracked vehicle, a combat vehicle, an aircraft, a boat or the like. Board vehicles 100, or means of transport as it may also alternatively be called, may be manned or unmanned. Furthermore, the vehicle 100 can be directly driver-controlled, controlled by a driver who is at a distance, remotely controlled and / or self-steering in various forms.

According to certain embodiments, the vehicle 100 includes means and logic for detecting an incident on board the vehicle 100 and notifies the driver, another person responsible for the advance of the vehicle 100 and / or the environment that the detected incident has occurred on board. Such an incident may consist of, for example, a passenger who has fallen over or been injured in some other way, passengers who are in a state of pain, passengers who appear lifeless / fainted, passengers in a fight, passengers with shortness of breath, passengers with cardiac arrest , passengers with symptoms of poisoning, passengers with incipient delivery, passengers with bleeding wounds, or the like.

In certain embodiments, the driver of the vehicle 100 may be made aware of the incident that occurred via an image, an audio signal, a light signal, a haptic / tactile signal, a voice message, or the like. In various embodiments, moreover, other surroundings can also be made aware of the incident that has occurred, such as other passengers, surrounding road users and / or a control center or the like.

In certain embodiments, the vehicle 100 may include surveillance sensors such as sample wiper cameras and laser scanners that individually, or collectively, provide an actual view of each passenger / stroller / wheelchair, etc. located in the vehicle 100 and their movement patterns. This makes it possible to detect a deviation from the normal, or incidental, accident or incident, for example.

When such an incident is detected, the driver and possibly also the surroundings can be communicated in a suitable manner, such as with warning sound / light, tactile, info on display with camera image of what has happened or the like. The fellow passengers can also be informed in a suitable way so that they can help according to certain embodiments. In some embodiments, the driver of the vehicle 100 is present. Instead, another person responsible for driving the vehicle 100 may be notified, such as a central monitoring station or the like.

Furthermore, a registration can be made of the driver's action, when he has been notified of the incident. Examples of such an appropriate measure may be, for example, that the driver acknowledges that he has discovered what happened, slows down or stops the vehicle 100, calls 112, starts first aid or the like. This or these actions may be predefined in a list according to certain embodiments. Thereby, the driver can also be given a recommendation as to what action he should take in connection with the accident that has occurred, via text message, voice message or the like.

For example, a passenger who has fallen and then has a persistent pain in an arm or a leg, swelling, shows abnormal mobility in an extremity or has the arm / leg in a unnatural position is suspected of having broken the arm / leg. A suitable measure may be to help the injured person up from the floor, support a broken arm with a mitella, scarf or the like and ensure that the injured person comes to a hospital or health center, for example by calling a taxi and helping the injured person. the vehicle.

If a passenger appears unconscious, an attempt to wake the person can first be made through indictment and shaking. If he does not wake up or react, check that breathing and heart rate are normal. If no breathing and / or pulse can be felt, turn the injured supine position open the airways and begin cardiac massage and artificial respiration. Do about 30 chest compressions and then inhale two breaths of air into the lungs of the injured person and repeat this. Call 112 and wait for ambulance personnel. If, on the other hand, there is normal breathing and heart rate, turn the injured person into a prone side position, etc. These are just a few examples of such instructions or appropriate measures to take when a certain scenario arises.

If the driver does not take such a listed action, a repeated and / or intensified perception can be made. If the driver also does not take any action now, according to an increasing scale, the driver's ability to drive the vehicle 100 can be appropriately limited, for example activating warning flashers or other lights in the vehicle 100, introducing a speed limit for the vehicle 100, introducing an acceleration limit for the vehicle 100, activating haptic / tactile signals in the vehicle's steering wheel or driver 's seat, request a red light at next traffic lights via V2x or similar communication technology, send information to the police authority to stop the vehicle 100, or carry out a combination of two or more of these actions.

This reduces the risk of an incident or accident on board vehicle 100 remaining undetected and unrepaired. Through various embodiments, the vehicle driver, other responsible person, fellow passengers, surrounding road users or the like can be made aware of an incident that has occurred, as if a personal injury has occurred, a broken femoral neck, baby on the floor counter similar, so that measures can be taken accordingly.

Figure 2 schematically shows a general example of passenger space in the vehicle 100.

In this example, there are a number of sensors 210 installed in the vehicle 100, which are arranged to detect an incident or accident on board the vehicle 100, such as, for example, that a passenger has fallen over. In the vehicle 100 there may be a sensor 210, or several sensors 210. These may cooperate with each other and be of the same type, or of different types in different embodiments. For example, a camera 210-1 can take pictures and through image analysis it can be established that a passenger behaves deviantly or appears to be injured. The vehicle100 may include a pressure sensor 210-2, which measures pressure and / or pressure change exerted on it by a single passenger. Such a pressure sensor 210-2 may be installed in the floor and / or seats of the vehicle, for example. In some embodiments, the vehicle 100 may include one or more light sensors 210-3. These may include a light beam and a switch that generates a single signal when the light beam is refracted. The vehicle 100 may also include one or more microphones 210-4 of the vehicle 100.

Signals from this or these sensors 210 can then be sent to a control unit in the vehicle100 for analysis. Such transmission can be made, for example, by wireless communication over a wireless interface according to certain embodiments. The wireless interface can be radio transmitters based on wireless communication technology such as 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), LTE-Advanced, Evolved UniversalTerrestrial Radio Access Network (E-UTRAN), Universal Mobile Telecommunications System (UMTS) ), Global System for Mobile Communications / Enhanced Data rate for GSMEvolution (GSM / EDGE), Wideband Code Division Multiple Access (WCDMA), World-Widelnteroperability for Microwave Access (WiMax), Wireless Local Area Network (WLAN) UltraMobile Broadband (UMB) , Bluetooth (BT), Near Field Communication (NFC) or infrared transmitter to name just a few possible examples of wireless communication. Alternatively, in some embodiments, information transfer may be performed over a tree-bound interface.

Said image analysis may, for example, include scale room representation to highlight and extract image structures on different scales, detection of features such as edges, regions, points of interest, corners and aces in images, matching point and line features between images, tracking image features and objects over time, structure and motion determination from point and line correspondences, construction of object models from stereo images and / or time-dependent image data, and recognition of three-dimensional objects from one or more two-dimensional images taken with the sensor 210 when constituted by a camera.

In this way, an incident in the passenger compartment of the vehicle 100 can be detected.

Figure 3 shows an example of vehicle interior in the vehicle 100, which includes a system 300, arranged to limit the driving of a vehicle when an accident is detected in the vehicle 100.

The vehicle 100 comprises a control unit 310, arranged to limit the driving of the vehicle when an accident is detected in the vehicle 100. In one embodiment, the vehicle 100 comprises a single screen 320, which can show, for example, a detected accident in the passenger compartment.

The control unit 310 is further arranged to receive sensor signals from one or more sensors210 in the vehicle 100. Furthermore, the control unit 310 may be arranged to analyze received sensor signals and detect an incident when one or more sensor values meet a condition, such as that a limit value is exceeded or the like.

The control unit 310 is further arranged to alert the driver to the incident which has occurred, in one or more ways such as via sound signal, light signal, voice message or the like.

Furthermore, the control unit 310 can also detect which action or actions the driver is taking. A comparison between the actions taken by the driver and a list of predefined actions that are suitable to take in different types of incidents can be made. If the driver takes an incorrect action, a message can be generated and the driver can be instructed to take the predefined action according to certain embodiments. Since the driver does not take any action at all, the driver's ability to drive the vehicle 100 may be limited in one or more different ways.

In this way, it can be avoided that an injured passenger remains undetected and / or unrepaired. This can be especially important to detect and help a fallen passenger, as he risks being injured even worse if someone else also falls or stumbles on the fallen person. Furthermore, it is especially important to be able to detect an unconscious passenger, as he or she cannot communicate with the outside world and demand attention.

Figure 4 illustrates an example of an embodiment of the invention. The flow chart in Figure 4 illustrates a method 400 in a vehicle 100, for limiting the driving of the vehicle when an accident is detected in the vehicle 100.

The method 400 may include a number of steps 401-405. Furthermore, the described steps 401-405 can be performed in a slightly different chronological order than the numerical order suggests. Some of the described steps 401-405 can also be performed in parallel with each other. Some steps, such as step 405, are performed only according to certain alternative embodiments of method 400. Method 400 includes the following steps: Step 401 An accident occurring in the vehicle 100 is detected with a sensor 210.

Such detection may also include detection of a hazardous passenger in the vehicle 100. One-risk passenger may be a passenger at increased risk of accident, such as a wheelchair-bound passenger; children in prams; disabled passengers; children; passengers with bodily injury; drunk passengers; passengers with an estimated age that has exceeded a certain limit value; standing passengers; or number of standing passengers in excess of a certain limit value or the like. This can be detected, for example, by image analysis of this passenger's movement pattern, where a movement pattern that deviates from a predefined normal behavior can be perceived as detection of a risk passenger. This may include, for example, deviation from a linear motion during movement, irregular motion, or the like. In this way it can be avoided that an accident occurs, by making the driver aware of the presence of the risk passenger, and / or that, for example, a speed limit and / or acceleration limit is introduced when a risk passenger is detected, according to certain embodiments.

Detection of incident, accident or hazardous passenger in the vehicle 100 can be made through image recognition with a sensor 210, which may be, for example, a camera 210-1; by analyzing signals from one or more pressure sensors 210-2 in the vehicle 100; genomic analysis of signals from one or more light sensors 210-3 in the vehicle 100; by analyzing sound recorded with one or more microphones 210-4 in the vehicle 100; or by a combination of these.

Step 402A person responsible for driving the vehicle 100 is informed of the detected 401 accident, or the detected hazardous passenger.

Said person responsible for driving the vehicle 100 may be, for example, the driver of the vehicle, a conductor in the vehicle 100 or a similar person who is physically in the vehicle100. However, in certain embodiments where the vehicle 100 is driverless, such a person may instead be constituted by a person who is at a distance from the vehicle 100, such as a central control unit or the like.

Said information of the detected 401 accident incident may also include information to the surroundings of the vehicle in order to draw their attention to the detected 401 accident incident in the vehicle 100, by light and / or sound signal, or the like.

In certain embodiments, the information of the detected 401 accident incident may also include visual presentation of the location in the vehicle 100 of said accident incident through an image on a monitor 320.

Step 403 An examination of whether said person has taken an action when he has been informed 402 if 401 detected the accident in the vehicle 100, wherein said action is included in a list of measures associated with the detected 401 accident.

Said measures included in the list of measures associated with the detected incident may, for example, include acknowledgment of the event that has occurred; lowering the speed and / or acceleration below a certain limit value, such as 20 km / h; stopping the vehicle 100; activation of hazard warning lights; summoning medically trained personnel (call 112 or equivalent emergency number); activating the vehicle's defibrillator, oxygen, or other medical equipment on board vehicle 100, or similar action.

In certain embodiments, such action associated with a particular incident may be communicated to the driver by a text message, voicemail or the like. In this way, the driver can be given guidance in a stressed, above and perhaps a little frightening situation, when a passenger, for example, bleeds heavily, and / or has stopped breathing or the like, which reduces the risk of incorrect action in the emergency situation that has arisen.

Step 404A limitation of the vehicle's performance is made, as examination 403 shows that no such action included in the list of actions has been taken.

Such restriction of vehicle performance may include a sequence of restrictive measures that increasingly reduce vehicle performance.

In some embodiments, the limitation of vehicle performance may include a vehicle internal measure, such as acceleration limitation of the vehicle 100; speed limitation of vehicle 100; activation of hazard warning lights; activating tactile vibrations in the vehicle's steering wheel, control knobs and / or driver's seat; activation of vehicle brake, or similar action; and / or a vehicle external action, such as sending a request red light at a subsequent traffic light; the request of the police authority to stop the vehicle 100; shutting down the vehicle's engine.

The limitation of the vehicle's performance when a hazardous passenger is detected 401 may in certain embodiments be limited to limitations in the vehicle's speed and / or acceleration / deceleration. As a result, jerky driving, sharp braking, etc. can be prevented when, for example, a highly intoxicated passenger has been detected on board. In this way, the risk of an accident occurring can be reduced, as such risk passengers may have extra difficulty in maintaining balance under such conditions.

In some embodiments, this restriction on vehicle performance may be inhibited when the vehicle 100 is driven toward a care unit, such as a hospital, medical center, physician, midwife, veterinarian, or the like. In this way, it can be avoided that the vehicle 100 is prevented from sitting in a serious emergency situation where a passenger needs to get in touch with such a care unit quickly, for example when a severely injured passenger needs emergency care or a pregnant woman in the passenger compartment suffers an emergency delivery.

Step 405This process step is performed only according to some, but not necessarily all, alternative embodiments. A delay can be calculated in relation to the vehicle's scheduled timetable due to the limitation 404 of the vehicle's driving, and passengers in the vehicle 100, waiting passengers at subsequent stations and / or a traffic control center can be informed of this calculated delay.

This gives these affected parties the opportunity to plan (re-plan) their trip and, for example, take another alternative means of transport instead, which saves time for them, and reduces irritation.

Furthermore, the signal receiver 510 may also be arranged to receive values from other sensors or meters in, or associated with, the vehicle 100, which such as altimeter, inclinometer, speedometer, thermometer, clock, etc. Such measurement data can refer to, for example, altitude, inclination, driving resistance to the ground, curvature of the plane, average cruising speed, time, date, weather, temperature, speed, gear engaged, vehicle type and / or vehicle weight .

Furthermore, the control unit 310 may also comprise a memory 525 according to certain embodiments, arranged to store, for example, a list of actions associated with a certain detected incident or accident that has occurred on board.
