[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solution of the present application is to obtain elastic wave data from an elastic wave sensor; determine the collision point location based on the elastic wave data; calculate the collision force value received by the collision point location based on the elastic wave data; compare the collision force value with the force threshold to determine braking measures.

[0024] At present, due to the large size of the battery, it is often placed under the floor of the vehicle, which is low to the ground and prone to scratches and collisions with the ground, causing damage to the battery and posing a safety hazard. Therefore, how to reduce the impact of battery collisions and improve battery safety is a problem that still needs to be solved.

[0025] In summary, the present application detects and processes the battery collision results through elastic wave sensors, thereby reducing the impact of battery collisions and improving battery safety.

[0026] Based on this, the embodiment of the present application provides a battery collision processing method based on elastic wave sensor, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the battery collision processing method based on elastic wave sensor of the present application.

[0027] In this embodiment, the battery collision processing method based on elastic wave sensor includes steps S10 to S40: Step S10: Acquire elastic wave data from the elastic wave sensor; It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a battery collision processing device based on an elastic wave sensor, etc. The following takes the battery collision processing device based on an elastic wave sensor as an example to illustrate this embodiment and the following embodiments.

[0028] It should be noted that the elastic wave sensor is a sensor that can detect elastic waves generated when an object is subjected to an external force. When the battery is subjected to an external force, a mechanical wave is generated, which propagates inside the battery to form an elastic wave. The elastic wave sensor uses principles such as the piezoelectric effect or the magnetostrictive effect to convert elastic waves into electrical signals, thereby realizing the detection of the force conditions of the battery. In this embodiment, the elastic wave sensor is used as a collision detector to obtain elastic wave data in four directions in the front, back, left and right of the battery frame. Real-time detection is performed while the vehicle is driving. If a battery scratch occurs, the wave generated at the collision point is transmitted to the elastic wave sensor through the battery frame, and each sensor will pick up the vibration wave and send it to the elastic wave sensor sampling module.

[0029] In a feasible manner, the step of acquiring elastic wave data of the elastic wave sensor includes: Acquiring initial elastic wave data from an elastic wave sensor; Processing the initial elastic wave data through a preset filter model to determine the collision type, wherein the preset filter model is trained by inputting elastic wave data of various collision types; A target collision type is determined from the collision types, and elastic wave data of the target collision type is obtained.

[0030] It is understandable that the battery will also generate elastic wave data when it is slightly touched, such as when a water drop hits the battery, so the initial elastic wave data needs to be filtered through a filtering model to obtain the final elastic wave data. Specifically, the initial elastic wave data can be parsed through a preset filtering model to determine the collision type; and the target collision type is determined from the collision types to obtain the elastic wave data of the target collision type.

[0031] Step S20: determining the collision point position according to the elastic wave data; It should be noted that elastic wave data can be acquired from different positions of the battery through multiple elastic wave sensors, and the position of the collision point can be determined based on the differences in these elastic wave data.

[0032] In a feasible manner, the step of determining the collision point position according to the elastic wave data includes: Obtaining position information and elastic wave intensity of an elastic wave sensor according to the elastic wave data; The collision point position is determined according to the position information and the elastic wave intensity.

[0033] It is understandable that when a battery collides, the elastic wave intensities sensed by elastic wave sensors at different positions are different. Therefore, the X, Y coordinates of the collision, that is, the collision point position, can be determined based on the position information of the elastic wave sensor and the corresponding elastic wave intensity.

[0034] Step S30: calculating the collision force value of the collision point according to the elastic wave data; It is understandable that the collision force value in this embodiment refers to the collision force value received by the battery in the vertical direction. The collision force value output in the Z direction of the battery can be calculated through the elastic wave data.

[0035] Step S40: Compare the collision force value with the force threshold to determine braking measures.

[0036] It is understandable that by comparing the collision force value with the force threshold, the collision level can be determined, such as a minor collision, a moderate collision, and a severe collision, and different response measures can be determined by different collision levels. When a collision occurs, the low-speed emergency braking system receives a trigger signal, quickly calls the interface with the chassis-related parts, and quickly shakes hands. After the handshake, an emergency braking request is sent. The low-speed emergency braking system will brake at a maximum speed of 3m / s 2 The emergency brake can effectively reduce the collision momentum and reduce or avoid greater battery damage.

[0037] In a feasible manner, after comparing the collision force value with the force threshold and determining the braking measure, the method further includes: Obtain panoramic video data from the surround view camera when a collision occurs; Environmental information when a collision occurs is obtained according to the panoramic video data.

[0038] It is understandable that when a collision occurs, the panoramic video data of the surround-view camera can obtain the ground conditions on which the vehicle drove when the collision occurred, which is used to analyze the cause of the collision. After a collision occurs, the 360 ​​panoramic image will be triggered actively, and it will be displayed in red in the chassis area and a reminder will be given. In addition, the four surround-view cameras arranged on the vehicle body will record the road conditions on which the vehicle has driven in real time while the vehicle is driving, and combined with the vehicle speed, the ground conditions on which the vehicle has driven will be memorized and spliced. After receiving the trigger signal from the elastic wave module, the 15 seconds before and after the trigger signal will be quickly cropped and spliced ​​into a 30-second video and sent to the car computer module. Customers can visit back in the car computer and confirm the status at the time of the collision.

[0039] This embodiment obtains elastic wave data from an elastic wave sensor; determines the collision point location based on the elastic wave data; calculates the collision force value received by the collision point location based on the elastic wave data; compares the collision force value with a force threshold value to determine braking measures.

[0040] In summary, this embodiment detects and processes the battery collision result through the elastic wave sensor, thereby reducing the impact of the battery collision and improving the battery safety.

[0041] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S40 includes steps S401 to S403: Step S401: when the collision level is a minor collision, a minor collision warning message is generated; It is understandable that when a minor collision is detected, the intelligent driving domain control module sends a signal to the vehicle computer module, and the vehicle computer pops up a window to remind "the vehicle battery is scratched, it is recommended to stop and check, and the collision video can be replayed in the emergency video". In this case, emergency braking is not requested to avoid false triggering.

[0042] Step S402: when the collision level is a moderate collision, deceleration is performed according to a preset deceleration until the speed reaches zero, and a moderate collision warning message is generated; It is understandable that in the event of a moderate collision, the intelligent driving module immediately requests braking from the chassis-related parts, requests to open 360, uploads a 30-second collision video, and pops up a window to remind "The power battery has collided, please stop immediately and contact the store." In addition, the vehicle requests double flashes to remind passing vehicles.

[0043] Step S403: When the collision level is a severe collision, the vehicle is decelerated according to a preset deceleration until the speed reaches zero, and the vehicle collision information is sent to a preset emergency address.

[0044] It is understandable that in the event of a severe collision, the battery has been deformed and there is a safety risk. The intelligent driving module immediately requests braking from the chassis-related parts and turns on the vehicle's double flashes. The vehicle's SOS module will urgently broadcast a rescue call to provide assistance to the driver as soon as possible to avoid personal injury.

[0045] In this embodiment, when the collision level is a minor collision, a minor collision warning message is generated; when the collision level is a moderate collision, the vehicle is decelerated according to the preset deceleration until the speed is zero, and a moderate collision warning message is generated; when the collision level is a severe collision, the vehicle is decelerated according to the preset deceleration until the speed is zero, and the vehicle collision information is sent to a preset emergency address.

[0046] In summary, this embodiment reduces the impact of battery collision and improves battery safety by taking different response measures for different collision levels.

[0047] For example, in order to help understand the implementation process of the battery collision processing method based on elastic wave sensor obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 3 The sensors include 4 elastic wave sensors and 4 surround-view cameras. The data collected by the elastic wave sensors are provided to the elastic wave processing module for processing. Then the low-speed emergency braking module decides on emergency braking based on the processing results, and performs emergency braking through the chassis-related parts execution module. In addition, the processing results of the elastic wave processing module and the data of the surround-view cameras are provided to the surround-view video processing module to produce panoramic video, which is displayed through the vehicle display module.

[0048] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the battery collision processing method based on elastic wave sensors of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0050] This embodiment obtains elastic wave data from an elastic wave sensor; determines the collision point location based on the elastic wave data; calculates the collision force value received by the collision point location based on the elastic wave data; compares the collision force value with a force threshold value to determine braking measures.
