Embodiments of the invention

In order to make the object, the features and the advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. The embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Embodiment 1

A vehicle damage detection method is described in the embodiment of the present application. Referring to FIG. 1-a, the vehicle damage detection method in the embodiment of the present application includes:

Step 101: Determine a collision position and a collision angle of the vehicle when a collision occurs in the vehicle;

In an application scenario, a plurality of sensor sets may be disposed around the vehicle, the sensor set including: a first sensor (eg, a vibration sensor) for acquiring vibration information and a second sensor (eg, a three-axis) for acquiring angle information Multi-axis sensor such as sensor, six-axis sensor or nine-axis sensor). For example, at least one sensor set may be disposed in each of the vehicle body positions in the front, rear, left, and right directions of the vehicle. As shown in FIG. 1-b, step 101 may include:

Step 1011: When a collision occurs in the vehicle, obtain, by each of the first sensors, vibration information of each vehicle body position when the vehicle collides;

In the embodiment of the present application, the vibration information includes: a vibration amplitude and a vibration period. Generally, when a vehicle collides, the vehicle body vibration of the vehicle may be different from the vibration of the vehicle body in other cases (ie, the vehicle does not collide). Therefore, in step 1011, when the vehicle collides, the vibration information of the corresponding vehicle body position at the time of the collision of the vehicle may be acquired by each of the first sensors deployed at the respective vehicle body positions of the vehicle, so as to perform the step based on the acquired vibration information. Processing of 1012.

Step 1012: Determine, according to the acquired vibration information, a target first sensor from each of the first sensors;

The amplitude of the vibration acquired by the target first sensor exceeds a preset upper limit value and the vibration period acquired by the target first sensor is less than a preset period lower limit value.

In the embodiment of the present application, when the amplitude of the vibration acquired by a certain first sensor exceeds a preset upper limit value, and the vibration period acquired by the first sensor is less than a preset period lower limit value, the first A sensor is the target first sensor. Wherein, the above-mentioned amplitude upper limit value and the cycle lower limit value may be determined by a change of the fixed vibration amplitude and the vibration period of the vehicle itself, which is not limited herein.

Step 1013: Determine, according to the vehicle body position where the first target first sensor is located, and the angle information acquired by the second sensor located in the same sensor set with the target first sensor in the collision of the vehicle, determine the collision position and the collision of the vehicle. angle;

Since the position of the body to be collided is generally large, the vibration is increased, and the vibration period is small. Therefore, in the embodiment of the present application, the collision position of the vehicle may be determined based on the position of the vehicle body where the first target is located. . For example, when there is only one target first sensor, the vehicle body position where the target first sensor is located may be the collision position of the vehicle, and when the target first sensor has more than one, the first sensor may be acquired according to each target. The difference in the amplitude of the vibration, the shortest path of the first body position (ie, the vehicle body position where the target first sensor having the largest vibration amplitude is located) to the second body position (ie, the vehicle body position where the target first sensor having the smallest vibration amplitude is located) The upper body position is determined as the collision position of the above vehicle. Specifically, the maximum vibration amplitude (ie, the amplitude of the vibration acquired by the target first sensor at the first vehicle body position) and the minimum vibration amplitude (ie, the vibration amplitude acquired by the target first sensor at the second vehicle body position) may be previously determined. a difference between the difference and the length, the length may be used to measure the distance between the collision position and the first body position on the shortest path from the first body position to the second body position, the difference is The length is negatively correlated; or the length may be used to measure the distance between the collision position and the second body position on the shortest path from the first body position to the second body position. In this case, the above The difference is positively related to the above length. Determining a vehicle body position on the shortest path of the first vehicle body position to the second vehicle body position as the collision position of the vehicle may include calculating a maximum vibration amplitude and a minimum vibration amplitude based on the vibration amplitude acquired by all the target first sensors. And a distance between the collision position and the first vehicle body position on the shortest path from the first vehicle body position to the second vehicle body position; and determining the above based on the distance The collision location of the vehicle.

After determining the collision position of the vehicle, the angle of collision of the vehicle may be determined based on the angle information acquired by the second sensor located in the same sensor set as the target first sensor when the vehicle is in the collision.

Of course, the method shown in FIG. 1-b is only a solution for determining the collision position and the collision angle of the vehicle provided by the embodiment of the present application. In practical applications, the collision position and the collision angle of the vehicle may also be determined by other methods, for example, for example. A plurality of contact sensors may be respectively disposed at a plurality of vehicle body positions where the vehicle is prone to collision. When the contact sensor senses the contact signal, the position of the vehicle body where the contact sensor is located may be determined as the collision position of the vehicle, and further, based on the contact The sensing result of the proximity sensor of the sensor determines the collision angle of the vehicle. Alternatively, the collision position and the collision angle of the vehicle may be determined by combining the contact sensor with the first sensor and the second sensor.

It should be noted that, in the embodiment of the present application, whether the vehicle collides may be known in various manners, for example, a large collision sound occurs when a traffic accident occurs, and the spectrum of the collision sound and other sounds are different. By collecting and analyzing the acoustic signals around the vehicle and combining the vibration signals of the vehicle body, it can be determined whether the vehicle collides; or the vehicle can be determined according to the vibration condition of each vehicle body position of the vehicle, which is not limited herein.

The projection of the vehicle is determined as the transmission path of the vehicle described above; or, the ray may be directly determined as the transmission path of the vehicle.

In another application scenario, in the case where the above-described collision position and the above-described collision angle are known, the transmission path of the vehicle can be determined in conjunction with the vibration condition in the middle of the vehicle chassis. Specifically, a third sensor may be disposed in a middle portion of the chassis of the vehicle; the third sensor is configured to acquire the vibration information mentioned in the foregoing step 101, and the sensitivity of the third sensor is higher than the first mentioned in the foregoing step 101. The sensor (for example, the third sensor described above may be a high sensitivity vibration sensor). In the step 102, the transmission path of the collision force on the vehicle is determined based on the collision position and the collision angle: acquiring, by the third sensor, vibration information of the middle of the chassis when the vehicle collides; based on the collision position, The collision angle and the vibration information when the middle portion of the chassis collides with the vehicle in the middle of the chassis determine the transmission path of the collision force on the vehicle. Specifically, determining the transmission path of the collision force on the vehicle based on the collision position, the collision angle, and the vibration information of the middle portion of the chassis in the collision of the vehicle may include: calculating a center point of the collision position to the middle of the chassis The angle between the connection and the collision angle is corrected based on the vibration amplitude of the middle portion of the chassis in the collision of the vehicle, so that the angle is negatively correlated with the vibration amplitude of the middle portion of the chassis in the collision of the vehicle. And determining a transmission path of the collision force on the vehicle based on the collision position and the corrected collision angle.

Step 103: Determine, according to the strength of the collision force and the transmission path, the degree of damage of each vehicle component on the transmission path;

In the embodiment of the present application, the vibration intensity and the vibration period obtained by the target first sensor closest to the collision position can be used to calculate the vibration intensity, and the vibration intensity can be further used as the strength of the collision force.

In step 103, based on the intensity of the collision force and the transmission path, the degree of damage of each of the vehicle components on the transmission path can be determined. Further, it is also possible to determine the loss value of each vehicle component based on the degree of damage of each vehicle component and generate a corresponding vehicle collision analysis report, so that the relevant personnel and the user can more accurately determine the damage of the vehicle based on the vehicle collision analysis report. Analysis.

Specifically, a damage relationship table may be set in advance for possible damage and corresponding loss value of each vehicle component of different vehicle types, and the damage value relationship table may include: correspondence relationship between damage degree and loss value of each vehicle component of the vehicle. The step 103 may further include: acquiring a damage value relationship table matching the vehicle type of the vehicle; determining a loss value of each of the vehicle components based on the damage degree of each of the vehicle components and the acquired damage value relationship table; generating and A vehicle crash analysis report containing the damage degree and loss value of each of the above-described vehicle components is output. Specifically, the generating and outputting the vehicle collision analysis report including the damage degree and the loss value of each of the vehicle components described above includes transmitting the vehicle collision analysis report to the mobile terminal associated with the vehicle. Of course, the vehicle collision analysis report including the damage degree and the loss value of each of the above-described vehicle components may be expressed as a vehicle collision analysis report including the damage degree and the loss value of each of the above-described vehicle components, which is not limited herein.

It should be noted that the vehicle damage detecting method in the embodiment of the present application may be implemented by a vehicle damage detecting device, which may be integrated in the OBD device of the vehicle, or may be integrated in the ECU unit system of the vehicle itself, or It can also be an electronic device that is independent and can communicate with the vehicle, which is not limited herein.

It can be seen that, in the embodiment of the present application, when the vehicle collides, the collision position and the collision angle of the vehicle are determined, and the transmission path of the collision force on the vehicle is determined based on the collision position and the collision angle, and then based on the collision. The strength of the force and the above-described transmission path respectively determine the degree of damage of each vehicle component on the transmission path. Since the vehicle components on the transmission path are the main force components of the collision force, these vehicle components are also more likely to be damaged by the collision.
