Background
During driving of a vehicle, a driver may develop medical emergency conditions such as seizures, syncopes, loss of consciousness, strokes, myocardial infarction, etc., which may result in the driver losing control of the vehicle and causing uncontrolled traffic accidents. Even if a safety accident does not occur immediately during the loss of control of the vehicle by the driver, it is still dangerous to keep the vehicle on the traffic lane and uncontrolled continued travel of the vehicle may hit other traffic participants or obstacles on the road.
Therefore, how to assist the driving operation of the driver in the case where the driver has a medical emergency becomes a technical problem that needs to be solved at present.
Disclosure of Invention
It is an object of the present invention to provide a method for coping with a medical emergency of a driver, a system for coping with a medical emergency of a driver and a computer program product to at least partially solve the problems of the prior art.
According to a first aspect of the present invention, there is provided a method for coping with a medical emergency of a driver, the method may comprise the steps of:
collecting health information of a driver, and evaluating whether a medical emergency of the driver occurs or not based on the health information of the driver;
if the medical emergency of the driver occurs, acquiring running state information and driving environment information of the vehicle, introducing the running state information and the driving environment information as evaluation factors, and evaluating whether the driving operation of the driver is reasonable; and is also provided with
If the driving operation of the driver is not reasonable, an acoustic and/or optical prompt message is sent to the driver.
The core concept of the invention is as follows: and evaluating the rationality of the driving operation of the driver when the driver is identified to have the medical emergency, and sending a driving operation prompt adapted to the current running state and the driving environment of the vehicle to the driver when the driving operation is not reasonable. According to the embodiment of the invention, the safety of drivers, other passengers in the vehicle and other road users can be effectively improved.
According to an alternative embodiment of the invention, it is possible to evaluate whether a medical emergency of the driver occurs based on physiological parameters of the driver collected by the wearable device and/or image information about the driver acquired by the on-board camera, wherein the driver does not have the ability to take over driving operations of the vehicle in the medical emergency. Illustratively, the medical emergency may include epilepsy, syncope, loss of consciousness, stroke, and/or myocardial infarction, among others.
According to a further alternative embodiment of the invention, the method may further comprise the steps of:
judging whether a driver performs a response operation on the prompt information within a preset time period;
if the driver does not perform a response operation with respect to the prompt message within a predetermined period of time, the driving operation of the vehicle is taken over by the vehicle control unit.
In this way, the driving operation of the vehicle can be automatically taken over by the vehicle control unit without the driver having the ability to take over the driving operation of the vehicle, so that the vehicle is out of the current dangerous driving situation, thereby avoiding traffic accidents of the vehicle and further improving the safety of the driver, other passengers in the vehicle and other road users.
According to another alternative embodiment of the present invention, in the case of a medical emergency of the driver, it is possible to detect traveling state information of the vehicle and determine whether an abnormal traveling state of the vehicle, including an abnormal acceleration state and/or an abnormal braking state, or the like, occurs based on the traveling state information. Alternatively, in the case where an abnormal running state of the vehicle occurs, the driving environment information of the vehicle may be acquired, and the running state information and the driving environment information may be introduced as evaluation factors to evaluate the rationality of the driving operation of the driver.
According to another alternative embodiment of the invention, in case of an abnormal acceleration state of the vehicle, object information in the driving direction of the vehicle may be detected, wherein the object may comprise an obstacle and/or other traffic participants. It may be determined whether a collision event of the vehicle with the object is likely to occur based on the running state information and the object information. If a collision event of the vehicle with the object is likely to occur, the driving operation of the driver is evaluated as unreasonable.
According to another alternative embodiment of the present invention, in the case that an abnormal acceleration state occurs in the vehicle, speed limit information of a lane in which the vehicle is currently located may be acquired. It may be determined whether an overrun event of the vehicle is likely to occur based on the running state information and the speed limit information. If an overrun event of the vehicle is likely to occur, the driving operation of the driver is evaluated as unreasonable.
According to another alternative embodiment of the present invention, in the case where an abnormal acceleration state occurs in the vehicle, curve information within a preset distance in front of the vehicle may be acquired. Based on the driving state information and the curve information, it may be determined whether an over-curve runaway event of the vehicle is likely to occur. If an over-bend out-of-control event of the vehicle is likely to occur, the driving operation of the driver is evaluated as unreasonable.
According to another alternative embodiment of the present invention, in the case that the abnormal braking state of the vehicle occurs, object information in front of the vehicle may be detected, and whether an object exists within a preset distance in front of the vehicle may be determined based on the object information, wherein the object may include an obstacle and/or other traffic participants. If no object exists within a preset distance in front of the vehicle, following vehicle information behind the vehicle may be detected, and it may be determined whether a rear-end collision accident of the vehicle with the following vehicle is likely to occur based on the running state information and the following vehicle information. If a rear-end collision accident of the vehicle with the following vehicle is likely to occur, the driving operation of the driver is evaluated as unreasonable.

Detailed Description
In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Fig. 1 shows a workflow diagram of a method for coping with a medical emergency of a driver according to an exemplary embodiment of the present invention. The following exemplary examples describe the method according to the invention in more detail.
The method may comprise steps S1 to S3. In step S1, health information of the driver may be collected, and whether a medical emergency of the driver occurs may be evaluated based on the health information of the driver. In the current embodiment of the present invention, image information about the driver may be acquired by an in-vehicle camera and whether a medical emergency of the driver occurs may be evaluated by means of a trained neural network model or classifier based on the image information. Within the meaning of the present invention, the medical emergency can be understood as follows: in such medical emergency situations, the driver may be experiencing severe pain, or the driver's awareness has been blurred, or even completely lost, and thus the driver is no longer provided with the ability to take over the driving operation of the vehicle. The medical emergency may include, for example, epilepsy, syncope, loss of consciousness, stroke, and/or myocardial infarction, among others. For example, when a painful expression, a twitch action, a syncope behavior, or the like of the driver is recognized through image processing, it may be determined that a medical emergency of the driver has occurred.
Optionally, it is also possible to evaluate whether a medical emergency of the driver has occurred based on the physiological parameters of the driver collected by the wearable device. The wearable device is worn on the body of the driver and may be configured to detect physiological parameters of the driver such as heart rate, pulse, blood pressure, respiratory rate, etc. When abnormal physiological parameters exceeding a preset threshold value occur, the driver can be judged to possibly generate medical emergency.
If a medical emergency of the driver occurs, in step S2, driving state information and driving environment information of the vehicle may be acquired, and the driving state information and the driving environment information may be introduced as evaluation factors to evaluate whether the driving operation of the driver is reasonable. Here, the running state information of the vehicle may include, for example, a running speed detected by a vehicle speed sensor and/or a running deceleration and/or a running acceleration detected by an acceleration sensor, and the like. Based on the running state information, it may be determined whether an abnormal running state of the vehicle, which may include, for example, an abnormal acceleration state and/or an abnormal braking state, etc., occurs.
In the case where an abnormal running state of the vehicle occurs, driving environment information of the vehicle may be acquired, and the running state information and the driving environment information may be introduced as evaluation factors to evaluate the rationality of the driving operation of the driver. Within the meaning of the present invention, the rationality of the driving operation can be understood as follows: in the current driving environment of the vehicle, whether the driving operation of the driver may affect the safety of the own vehicle and/or surrounding vehicles, or whether traffic regulations may be violated. If the driving maneuver by the driver is not reasonable, an acoustic and/or optical warning message about the driving maneuver may be sent to the driver in step S3. The following is a detailed description in connection with specific driving scenarios.
Fig. 2 shows a workflow diagram of a method for coping with a medical emergency of a driver according to another exemplary embodiment of the present invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
Here, the step S2 may include steps S211 to S213. In step S211, it is determined whether an abnormal acceleration state of the vehicle occurs based on the running state information of the vehicle. For example, in the driving scenario shown in fig. 7, when the running acceleration and/or the running speed of the vehicle 2 exceeds a preset threshold value, an abnormal acceleration state of the vehicle 2 may be recognized, i.e., the driver of the vehicle 2 may perform a severe acceleration operation.
When the abnormal acceleration state of the vehicle 2 occurs, object information in the traveling direction of the vehicle 2, including, for example, other traffic participants and/or obstacles (e.g., fences, walls of roadside buildings), and the like, may be detected in step S212. In the embodiment shown in fig. 7, the position information and/or the size information of the object 3 in the traveling direction of the vehicle 2 may be detected by an in-vehicle front camera, a front radar sensor, a front lidar sensor, or the like.
In step S313, it may be determined whether a collision event of the vehicle 2 with the object 3 is likely to occur based on the running state information and the object information. In this case, in particular, if the vehicle 2 continues to travel based on the current driving operation instruction, the vehicle 2 may collide with the object 4 in the traveling direction, whereby the driving operation of the driver is evaluated as unreasonable. Accordingly, in step S3, an optical prompt message may be sent to the driver of the vehicle 2 through an instrument panel, a head-up display screen, a central control display screen, or the like, and/or an acoustic prompt message may be sent to the driver of the vehicle 2 through an on-vehicle voice device, for example, to prompt the driver that a brake pedal should be operated to perform deceleration, so as to avoid a collision accident between the vehicle 2 and the object 3 in the driving direction.
Fig. 3 shows a workflow diagram of a method for coping with a medical emergency of a driver according to another exemplary embodiment of the present invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
Here, the step S2 may include steps S221 to S223. In step S221, it is determined whether an abnormal acceleration state of the vehicle occurs based on the running state information of the vehicle. When the running acceleration and/or the running speed of the vehicle 2 exceeds a preset threshold value, an abnormal acceleration state of the vehicle 2, i.e., a severe acceleration operation may be performed by the driver of the vehicle 2, may be recognized.
When the abnormal acceleration state of the vehicle 2 occurs, speed limit information of the lane in which the vehicle 2 is currently located may be acquired in step S222. For example, in the driving scenario shown in fig. 8, the speed limit traffic sign 4 on the current lane may be identified based on the image acquired by the in-vehicle front camera, thereby acquiring the speed limit information of the current lane; the speed limit information of the lane where the vehicle 2 is currently located can also be obtained through the positioning information of the vehicle and the high-precision map information in the vehicle-mounted navigation module.
In step S223, it may be determined whether an overrun event of the vehicle 2 is likely to occur based on the running state information and the speed limit information. If an overrun driving event of the vehicle 2, i.e., the current driving speed of the vehicle 2 has exceeded or is approaching the highest speed limit of the lane in which the vehicle 2 is located, may occur, the driving operation of the driver is evaluated as unreasonable. Accordingly, in step S3, an optical prompt may be sent to the driver of the vehicle 2 through a dashboard, a head-up display, a center control display, or the like, and/or an acoustic prompt may be sent to the driver of the vehicle 2 through an on-board voice device, for example, to prompt the driver that a brake pedal should be operated to slow down, thereby avoiding an overrun event of the vehicle 2.
Fig. 4 shows a workflow diagram of a method for coping with a medical emergency of a driver according to another exemplary embodiment of the present invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
Here, the step S2 may include steps S231 to S233. In step S231, it is determined whether an abnormal acceleration state of the vehicle occurs based on the running state information of the vehicle. When the running acceleration and/or the running speed of the vehicle 2 exceeds a preset threshold value, an abnormal acceleration state of the vehicle 2, i.e., a severe acceleration operation may be performed by the driver of the vehicle 2, may be recognized.
When the abnormal acceleration state of the vehicle 2 occurs, curve information within a preset distance in front of the vehicle 2 may be acquired in step S232. For example, in the driving scene shown in fig. 9, the turning traffic sign 6 in front of the vehicle 2 may be identified based on the image acquired by the in-vehicle front camera, and also information on the distance, corner, etc. of the curve may be acquired based on the image on the curve; the information such as the distance and the corner of the curve in front of the vehicle 2 can also be obtained from the positioning information of the vehicle 2 and the high-precision map information in the in-vehicle navigation module.
In step S233, it may be determined whether an excessive-bending out-of-control event of the vehicle 2 is likely to occur based on the running state information and the curve information. It will be appreciated that in the event that the vehicle 2 is driven into a curve with a large corner at an excessively high driving speed, an accident may occur in which the vehicle 2 is driven out of the curve, or even is turned over. If an over-bend out-of-control event of the vehicle is likely to occur, the driving operation of the driver is evaluated as unreasonable. Accordingly, in step S3, an optical prompt may be sent to the driver of the vehicle 2 through a dashboard, a head-up display, a central control display, or the like, and/or an acoustic prompt may be sent to the driver of the vehicle 2 through an on-board voice device, for example, to prompt the driver that the brake pedal should be operated to slow down, so as to avoid an over-bend out-of-control event of the vehicle 2.
Fig. 5 shows a workflow diagram of a method for coping with a medical emergency of a driver according to another exemplary embodiment of the present invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
Here, the step S2 may include steps S241 to S243. In step S241, it is determined whether the vehicle is in an abnormal braking state based on the running state information of the vehicle. When the running deceleration of the vehicle 2 exceeds a preset threshold value, an abnormal braking state of the vehicle 2, i.e., a severe braking operation that may be performed by the driver of the vehicle 2, may be recognized.
If an abnormal braking state of the vehicle 2 occurs, object information in front of the vehicle 2 may be detected and it may be determined whether an object including, for example, other traffic participants and/or obstacles (e.g., fences, walls of roadside buildings), etc., exists within a preset distance in front of the vehicle 2 based on the object information in step S242. In the embodiment shown in fig. 9, the position information and/or the size information of the object 3 in the traveling direction of the vehicle 2 may be detected by an in-vehicle front camera, a front radar sensor, a front lidar sensor, or the like.
If no object is present within the preset distance in front of the vehicle 2, then in step S243, following vehicle information behind the vehicle may be detected, and it may be determined whether a rear-end collision accident of the vehicle 2 with the following vehicle 5 is likely to occur based on the running state information and the following vehicle information. Here, the distance and/or the travel speed of the following vehicle 5 behind the vehicle 2 may be detected by an in-vehicle rear camera, a rear radar sensor, a rear lidar sensor, or the like, thereby evaluating the possibility of a rear-end collision accident of the vehicle 2 with the following vehicle 5. If a rear-end collision accident of the vehicle 2 with the following vehicle 5 is likely to occur, the driving operation of the driver is evaluated as unreasonable. Accordingly, in step S3, an optical prompt message may be sent to the driver of the vehicle 2 through an instrument panel, a head-up display screen, a center control display screen, or the like, and/or an acoustic prompt message may be sent to the driver of the vehicle 2 through an on-vehicle voice device, for example, to prompt the driver that an accelerator pedal should be operated to maintain the running speed, so as to avoid a rear-end collision accident of the vehicle 2 with the following vehicle 5.
According to the invention, the rationality of the driving operation of the driver is evaluated under the condition that the driver is identified to have the medical emergency, and the driving operation prompt adapted to the current running state and the driving environment of the vehicle is sent to the driver under the condition that the driving operation is not reasonable, thereby effectively improving the safety of the driver, other passengers in the vehicle and other road users.
Fig. 6 shows a workflow diagram according to another exemplary embodiment of the invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
The method may further comprise steps S4 and S5. After the transmission of the acoustic and/or optical information about the driving maneuver to the driver, it may be determined in step S4 whether the driver has performed a response maneuver about the information within a predefined time period. In an alternative embodiment of the invention, the length of the time period may be fixed or may be dynamically adjusted based on the current running state information and the driving environment information of the vehicle 2.
If the driver does not perform a response operation with respect to the prompt message within a predetermined period of time, which means that the driver is no longer provided with the ability to take over the driving operation of the vehicle, the driving operation of the vehicle 2 may be taken over by the vehicle control unit 15 in step S5. Illustratively, in the driving scenario shown in fig. 7, a braking operation may be automatically performed by the vehicle control unit 15 to stop the vehicle 2, thereby avoiding a collision accident of the vehicle 2 with the object 3 in the traveling direction; in the driving scenario shown in fig. 8, a braking operation may be automatically performed by the vehicle control unit 15 to control the vehicle 2 to perform deceleration running, thereby avoiding an overrun event of the vehicle 2; in the driving scenario shown in fig. 9, a braking operation may be automatically performed by the vehicle control unit 15 to control the vehicle 2 to perform a deceleration running and to drive into a curve at an adapted speed, thereby avoiding an out of control of the vehicle 2 over-bending; in the driving scenario shown in fig. 10, it is possible to automatically perform an acceleration operation by the vehicle control unit 15 and control the vehicle 2 to automatically accelerate to a traveling speed before braking, thereby avoiding a rear-end collision accident of the vehicle 2 with the following vehicle 5.
According to the invention, the driving operation of the vehicle can be automatically taken over by the vehicle control unit under the condition that the driver does not have the capability of taking over the driving operation of the vehicle, so that the vehicle is separated from the current dangerous driving condition, thereby avoiding traffic accidents of the vehicle and further improving the safety of the driver, other passengers in the vehicle and other road users.
In addition, it should be noted that the sequence numbers of the steps described herein do not necessarily represent a sequential order, but are merely a reference number, and the order may be changed according to circumstances as long as the technical object of the present invention can be achieved.
