Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In order to improve the accuracy of vehicle collision determination, the present disclosure provides a method, an apparatus, a readable storage medium, and an electronic device for determining a vehicle collision. The method may be applied to a vehicle (e.g., a vehicle controller), a remote system communicatively coupled to the vehicle, and the like. Preferably, the method may be applied to a remote system communicatively connected to the vehicle. Therefore, even if the vehicle has a functional fault, the vehicle collision can be judged through the remote system in communication connection with the vehicle, and then collision alarm can be timely carried out according to the collision judgment result, so that the accident loss can be reduced, and the life safety of a driver can be guaranteed.
The method for determining a vehicle collision provided by the present disclosure is explained in detail below, wherein the method is applied to a remote system as an example in the following embodiments. FIG. 1 is a flow chart illustrating a method of determining a vehicle collision according to an exemplary embodiment. As shown in fig. 1, the method may include the following steps 101 to 103, wherein the method is applied to a remote system in the following embodiments.
In step 101, a target time period is determined based on the vehicle collision information.
In the present disclosure, the collision information may be used to indicate whether a collision signal is received. When the collision sensor arranged in front of the vehicle detects that the collision force is larger than a certain value, a collision signal is generated and sent to the remote system, and the remote system receives the collision signal. When the remote system receives the collision signal, the collision information indicates that the collision signal is received; when the remote system does not receive the collision signal, the collision information indicates that the collision signal is not received. Illustratively, the collision information may be represented by logical operators 0 and 1, wherein when the collision information is "0", it indicates that the remote system has not received the collision signal, and when the collision information is "1", it indicates that the remote system has received the collision signal.
When the collision information indicates that the collision signal is received, in order to improve the accuracy of the collision determination, whether the vehicle actually collides or not can be further determined according to the vehicle speed and the acceleration of the vehicle in the next time period; and when the collision information indicates that the collision signal is not received, whether the vehicle collides or not can be further determined according to the vehicle speed and the acceleration of the vehicle in the latest period or the next period of the vehicle. That is, the collision information is different, and the vehicle speed and the acceleration, on which the collision of the vehicle is determined, may also be different, that is, the vehicle collision determination is performed using the vehicle speed and the acceleration at different time periods. Therefore, after the collision information is acquired, the target time period may be determined according to the collision information (i.e., step 101 is executed), and then whether the vehicle has a collision may be determined according to the vehicle speed and the acceleration within the target time period.
Specifically, the above-described target period may be determined by: if the collision information indicates that the collision signal is received, determining a time interval with the current time as the starting time and the time interval as a first preset time length (for example, 30s) as a target time interval; if the collision information indicates that no collision signal is received, the target time period is any one of the following: the time interval is a second preset time period with the current time as the starting time and the time interval as the second preset time period, the time interval is a third preset time period with the current time as the ending time and the time interval is a fourth preset time period with the current time as the middle time and the time interval as the fourth preset time period (for example, the fourth preset time period is six minutes, and the target time period is a time period from five minutes before the current time to one minute after the current time).
It should be noted that the first preset time period, the second preset time period, the third preset time period, and the fourth preset time period may be values set by a user, or may also be default empirical values, and they may be different, may also be partially equal, may also be all equal, and are not specifically limited in this disclosure.
In step 102, the vehicle speed and acceleration of the vehicle within a target time period are acquired.
In step 103, it is determined whether the vehicle has collided with based on the vehicle speed and the acceleration.
In one embodiment, if the maximum value of the absolute values of the accelerations at the respective times within the target period is less than a first preset acceleration threshold (e.g., 1 m/s)2) And if the vehicle speed at the last moment of the target time interval is not zero, namely the vehicle is in a running state and the vehicle speed does not change obviously, determining that the vehicle does not collide. If the maximum value of the absolute values of the accelerations at the respective times within the target time period is greater than or equal to the first preset acceleration threshold value and the vehicle speed at the last time within the target time period is less than or equal to a preset speed threshold value (e.g., 10km/h), it is determined that the vehicle has collided.
In the technical scheme, whether the vehicle collides or not is determined not directly according to the collision information of the vehicle, but a target time period is determined according to the collision information, and then whether the vehicle collides or not is determined according to the vehicle speed and the acceleration of the vehicle in the target time period. Therefore, the accuracy of vehicle collision judgment can be improved, and the safety measures (such as air bag ejection, alarm and the like) can be accurately and timely triggered. Therefore, the problems that manpower and material resources are wasted due to false triggering of safety measures and the life safety of a driver cannot be guaranteed due to the fact that the vehicle actually collides but the safety measures are not triggered can be avoided.
In addition, when it is determined that the vehicle has a collision, the collision degree of the vehicle (wherein the collision degree may include slight, medium and severe) may be further obtained, so as to make a subsequent rescue plan according to the collision degree. For example, when the vehicle is in a light collision or a medium collision, a vehicle maintenance station can be contacted for rescue, and when the vehicle is in a heavy collision, a hospital and a traffic police can be contacted for rescue. Specifically, as shown in fig. 2, the method may further include the following step 104.
In step 104, if it is determined that the vehicle has collided, the degree of collision of the vehicle is determined based on the acceleration.
In the present disclosure, the degree of collision of the vehicle may be determined by the acceleration of the vehicle, that is, the greater the absolute value of the acceleration, the more severe the degree of collision of the vehicle. Specifically, the degree of collision of the vehicle may be determined by: if the maximum value of the absolute values of the acceleration at each time within the target time interval is greater than or equal to the first preset acceleration threshold and less than a second preset acceleration threshold (e.g., 3 m/s)2) The degree of collision is slight; if the maximum value of the absolute values of the acceleration at each time within the target time interval is greater than or equal to the second preset acceleration threshold and less than a third preset acceleration threshold (e.g., 10 m/s)2) The degree of collision is medium; if the maximum value of the absolute values of the acceleration at each moment in the target time interval is greater than or equal to the third preset acceleration threshold, the collision degree is serious.
It should be noted that, the first preset acceleration threshold, the second preset acceleration threshold, and the third preset acceleration threshold may be set by a user, or may be default empirical values, which are not specifically limited in this disclosure.
In addition, in order to improve the accuracy of the determined degree of collision of the vehicle, in determining the degree of collision of the vehicle, other state information of the vehicle and the collision information may be combined in addition to the acceleration of the vehicle. Specifically, as shown in fig. 3, the method may further include the following step 105.
In step 105, the state information of the vehicle within the target period is acquired.
In the present disclosure, the status information may include at least one of: engine state, vehicle longitude and latitude information, gear information, ignition switch state, vehicle door state, tire pressure state and road type of driving.
The engine state may include normal operation, abnormal operation, and a first state, where the first state may be used to represent that the engine state is not obtained. Specifically, when the vehicle fails, a communication connection between the vehicle and the remote system may fail, or the vehicle may not acquire the engine state, so that the remote system may not acquire the engine state, that is, the engine state is not acquired, and at this time, the engine state is the first state.
The ignition switch state may include on, off, and a second state, where the second state may be used to characterize that the ignition switch state was not acquired. Specifically, when the vehicle fails, a communication connection between the vehicle and the remote system may be failed, or the vehicle may not acquire the ignition switch state, so that the remote system may not acquire the ignition switch state, that is, the ignition switch state is not acquired, and at this time, the ignition switch state is the second state.
The door state may include open and closed.
The tire pressure state may include a normal state (in which the tire pressure state is determined to be normal when the tire pressure is within the range of [2.1bar, 3bar ]), an abnormal state (in which the tire pressure state is determined to be abnormal when the tire pressure is less than 2.1 bar), and a third state, wherein the third state may be used to represent a tire pressure unacquired state. Specifically, when the vehicle fails, a communication connection between the vehicle and the remote system may fail, or the vehicle may not acquire the tire pressure state, so that the remote system may not acquire the tire pressure state, that is, the tire pressure state is not acquired, and at this time, the tire pressure state is the third state.
The types of roads traveled may include highways, national roads, provincial roads, urban roads, and other roads (e.g., factory roads, forest roads, rural roads, etc.).
After the state information is acquired by the above 105, the degree of collision of the vehicle can be determined based on the acceleration, the state information, and the collision information (i.e., step 104). Specifically, the degree of collision of the vehicle may be determined by: if the collision information indicates that the collision signal is received, determining the collision degree of the vehicle according to the acceleration and the state information and a first preset rule; and if the collision information indicates that the collision signal is not received, determining the collision degree of the vehicle according to the acceleration and the state information and a second preset rule.
Wherein, in the case that the collision information indicates that the collision signal is received, the collision degree of the vehicle may be determined according to a first preset rule as follows: determining that the degree of collision of the vehicle is slight if the acceleration satisfies the condition G1 shown in table 1 and the status information satisfies the conditions corresponding to the status items included in the status information shown in the fourth row in table 2; if the acceleration satisfies the condition G2 shown in table 1 and the status information satisfies the conditions corresponding to the status items included in the status information shown in the third row in table 2, it is determined that the degree of collision of the vehicle is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the conditions corresponding to the respective state items included in the state information shown in the second row in table 2, it is determined that the degree of collision of the vehicle is severe.
In the case where the collision information indicates that the collision signal is not received, the degree of collision of the vehicle may be determined according to a second preset rule as follows: determining that the degree of collision of the vehicle is slight if the acceleration satisfies the condition G1 shown in table 1 and the status information satisfies the conditions corresponding to the status items included in the status information shown in the fourth row in table 3; if the acceleration satisfies the condition G2 shown in table 1 and the status information satisfies the conditions corresponding to the status items included in the status information shown in the third row in table 3, it is determined that the degree of collision of the vehicle is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the conditions corresponding to the respective state items included in the state information shown in the second row in table 3, it is determined that the degree of collision of the vehicle is severe.
Illustratively, the status information includes: engine state, vehicle longitude and latitude information, gear information, ignition switch state, vehicle door state, tire pressure state and road type of driving. Accordingly, the degree of collision of the vehicle is determined by determining whether the acceleration satisfies conditions corresponding to the acceleration items shown in table 2 or table 3 (i.e., conditions shown in the second column of table 2 or table 3), whether the state information satisfies conditions corresponding to the state items of the engine state, the vehicle latitude and longitude information, the shift position information, the ignition switch state, the door state, the tire pressure state, the type of road on which the vehicle is traveling shown in table 2 or table 3 (i.e., conditions shown in the third to ninth columns of table 2 or table 3).
Specifically, in the case where the collision information indicates that the collision signal is received: when the acceleration satisfies a condition G1 shown in table 1 and the state information satisfies conditions shown in the fourth row in table 2 (a1, B1 or B2, C1, C2 or C3, D1, D2, D3 or D4, E1 or E2, F1, H1 or H2), it is determined that the degree of collision is slight; when the acceleration satisfies conditions G2 shown in table 1 and the state information satisfies conditions (a1 or a2, B1, C2 or C3, D1, D2, D3 or D4, E1 or E2, F1 or F2, H2 or H3) shown in the third row in table 2, it is determined that the degree of collision is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the conditions (a1 or a2, B1, C1, C2 or C3, D1, D2 or D3, E1 or E3, F2 or F3, H2 or H3) shown in the second row in table 2, it is determined that the degree of collision is severe.
In the event that the collision information indicates that no collision signal has been received: when the acceleration satisfies a condition G1 shown in table 1 and the state information satisfies conditions shown in the fourth row in table 3 (a1, B1 or B2, C1, C2 or C3, D1, D2, D3 or D4, E1 or E2, F1, H1 or H2), it is determined that the degree of collision is slight; when the acceleration satisfies a condition G2 shown in table 1 and the state information satisfies the respective conditions (a1 or a2, B1, C2 or C3, D1, D2, D3 or D4, E1 or E2, F1 or F2, H2 or H3) shown in table 3, it is determined that the degree of collision is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the respective conditions (a1, B1, C1, C2 or C3, D1, D2 or D3, E1 or E3, F2 or F3, H2 or H3) shown in table 3, it is determined that the degree of collision is serious.
As another example, the status information includes: engine status, vehicle latitude and longitude information. Accordingly, the degree of collision of the vehicle is determined by determining whether the acceleration satisfies the conditions corresponding to the acceleration items shown in table 2 or table 3 (i.e., the conditions shown in the second column in table 2 or table 3), whether the state information satisfies the conditions corresponding to the two state items of the engine state, the vehicle latitude and longitude information shown in table 2 or table 3 (i.e., the conditions corresponding to the third and fourth columns in table 2 or table 3).
Specifically, in the case where the collision information indicates that the collision signal is received: determining the degree of collision to be slight when the acceleration satisfies a condition G1 shown in table 1 and the state information satisfies conditions (a1, B1, or B2) shown in the fourth row, the third column, the fourth row, the fourth column in table 2; when the acceleration satisfies the condition G2 shown in table 1 and the state information satisfies the conditions (a1 or a2, B1) shown in the third row, third column, and fourth column in table 2, it is determined that the degree of collision is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the conditions (a1 or a2, B1) shown in the third column of the second row and the fourth column of the second row in table 2, the degree of collision is determined to be serious.
In the event that the collision information indicates that no collision signal has been received: determining the degree of collision to be slight when the acceleration satisfies a condition G1 shown in table 1 and the state information satisfies conditions (a1, B1, or B2) shown in the fourth row, the third column, the fourth row, the fourth column in table 3; when the acceleration satisfies the condition G2 shown in table 1 and the state information satisfies the conditions (a1 or a2, B1) shown in the third row, third column, and fourth column in table 3, it is determined that the degree of collision is medium; when the acceleration satisfies the condition G3 shown in table 1 and the state information satisfies the conditions (a1, B1) shown in the third column of the second row and the fourth column of the second row in table 3, the degree of collision is determined to be serious.
