The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The collision data collection system, method and vehicle of the embodiment of the present application are described below with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the collection of traffic accident data at the current stage is mainly based on manual collection by professional and technical personnel, and the timeliness and accuracy of data collection are poor, the present application provides a collision data collection system, in which at least one detection component detects the current collision data of the vehicle, and the control component records the current collision data when the current collision data meets the preset airbag detonation condition, and generates a detonation signal at the same time, so that the peripheral load device simulates the detonation of the airbag according to the detonation signal, isolates the detonation of the airbag of the vehicle, and reads the current collision data recorded by the control component through the central domain controller.

The automatic collection and classified storage of traffic accident data can be realized, and the accuracy and timeliness of the collected accident data are improved.

[0027] Specifically, Figure 1 A block diagram of a collision data acquisition system provided in an embodiment of the present application.

[0028] like Figure 1 As shown, the collision data acquisition system includes: at least one detection component 100, a peripheral load device 200, a control component 300 and a central domain controller 400.

[0029] Among them, at least one detection component 100 is arranged around the vehicle to detect the current collision data of the vehicle; the peripheral load device 200 is used to simulate the detonation of the airbag, and isolate the detonation of the airbag of the vehicle while simulating the detonation of the airbag according to the detonation signal; the control component 300 is respectively connected to the peripheral load device 200 and all the detection components 100, and the control component 300 is used to record the current collision data when the current collision data meets the preset airbag detonation condition, and generate a detonation signal at the same time, so that the peripheral load device 200 simulates the detonation of the airbag according to the detonation signal while isolating the detonation of the airbag of the vehicle; the central domain controller 400 is connected to the control component 300, and the central domain controller 400 is used to read the current collision data recorded by the control component.

[0030] Specific as Figure 2 As shown, at least one detection component 100 is a collision peripheral sensor, including a driver side front collision sensor, a passenger side front collision sensor, a driver side column sensor, a door pressure sensor, etc., which are arranged at the front of the vehicle. The connection diagram of the peripheral load device 200 is shown in FIG. Figure 3 As shown, 1 is an airbag controller with a detonation function, that is, the control component 300 in the embodiment of the present application, 2 is a peripheral load device 200, specifically an airbag or a seat belt, and the peripheral load device 200 is connected to the network at the vehicle end through the adapter board connector 3.

[0031] The current collision data includes data such as vehicle speed and acceleration when the vehicle collides.

[0032] Specifically, the collision peripheral sensors are collided simultaneously, the current collision data is detected by the airbag controller and the collision sensor, and the severity of the collision is identified by the system calibration conditions. When the detonation threshold crosses the calibration threshold line set by the detonation algorithm, it is determined that the current collision data meets the preset airbag detonation conditions. At this time, the sending bus CrashOutputSt is triggered to generate a detonation signal. The control component 300 detonates the peripheral load device 200 (i.e., the airbag or seat belt) according to the detonation signal, and records the current collision data at the same time. Since the peripheral load device 200 is capable of isolating the peripheral ignition circuit, the airbag of the real vehicle will not detonate. Further, Figure 4As shown, when the control component 300 ignites the airbag or the seat belt, it records the current collision data and synchronously sends out a CANFD signal and a hard-wired flipped PWM CRO signal. The central domain controller 400 reads the current collision data based on the CANFD signal and the PWM CRO signal.

[0033] Optionally, in some embodiments, the above-mentioned collision data collection system 10 further includes: an external collection component 500 for collecting historical collision data of multiple target vehicles and a communication component 600. One end of the communication component 600 is connected to the external collection component, and the other end of the communication component 600 is connected to the central domain controller 400 for transmitting the historical collision data to the central domain controller 400.

[0034] Optionally, in some embodiments, the above-mentioned collision data collection system 10 further includes: a target cloud 700 and a vehicle communication component 800. The vehicle communication component 800 is connected to the central domain controller 400 and is used to upload historical collision data and / or current collision data to the target cloud 700.

[0035] In an embodiment of the present application, the external acquisition component 500 is an external diagnostic instrument, such as CANoe software, and the communication component 600 is an OBD interface. The external acquisition component 500 is used to collect historical collision data of multiple target vehicles. One end of the OBD interface is connected to the external acquisition component 500, and the other end of the OBD interface is connected to the central domain controller 400 for transmitting historical collision data to the central domain controller 400. The central domain controller 400 reads the historical collision data and / or reads the current collision data.

[0036] Specifically, when the central domain controller 400 reads historical collision data and / or current collision data, it packages the historical collision data and / or current collision data, and sends the packaged historical collision data and / or current collision data to the on-board communication component 800 based on SOMEIP, and the on-board communication component 800 uploads the packaged data to the target cloud 700.

[0037] Optionally, in some embodiments, the target cloud 700 includes: a data processing unit connected to the vehicle communication component 800, the data processing unit parses historical collision data and / or current collision data, and generates a target readable report based on the parsing results.

[0038] Optionally, in some embodiments, the above-mentioned collision data collection system 10 further includes: a display component 900 connected to the data processing unit, for displaying a target readable report.

[0039] Among them, the display component 900 can be the backend of the cloud monitoring system, which is usually deployed on a cloud server. The cloud server can be remotely logged in and started through the experimental computer to view the historical collision data and / or current collision data received by the backend of the cloud monitoring system.

[0040] Specifically, the target cloud 700 includes a data processing unit for parsing the packaged historical collision data and / or the packaged current collision data, and generating a target readable report based on the parsing results, and sending the target readable report to the display component 900 for display, so that the user can view the target readable report.

[0041] Optionally, in some embodiments, the above-mentioned collision data collection system 10 further includes: an alarm component 1000, the alarm component 1000 is connected to the target cloud 700, and the alarm component 1000 issues an alarm reminder when the current collision data is transmitted to the target cloud 700.

[0042] Among them, the alarm component 1000 can be an alarm device installed inside or outside the vehicle, which can trigger an alarm through sound, light, vibration, etc., or it can be a device that can remotely monitor the status of the vehicle and can perform real-time monitoring and alarm through mobile phone applications or software on computers.

[0043] Optionally, in some embodiments, the alarm component 1000 includes: an acoustic alarm unit, the acoustic alarm unit is connected to the target cloud, and the acoustic alarm unit performs an acoustic alarm reminder when the current collision data is transmitted to the target cloud 700; and / or, an optical alarm unit, the optical alarm unit is connected to the target cloud 700, and the optical alarm unit performs an optical alarm reminder when the current collision data is transmitted to the target cloud.

[0044] Specifically, both the acoustic alarm unit and the optical alarm unit are connected to the target cloud 700. After receiving historical collision data and / or current collision data on the target cloud 700, the acoustic alarm unit of the alarm component 1000 of the remote monitoring device can be controlled by wireless control to give an acoustic alarm reminder, and the optical alarm unit can be controlled to give an optical alarm reminder.

[0045] Among them, the embodiment of the present application also compares the collision data read by the external acquisition component 500, the collision data read by the central domain controller and the collision data in the cloud to verify the feasibility and effectiveness of the collision data acquisition system of the embodiment of the present application.

[0046] There are two ways to read data from a simulated real vehicle, mainly the following two ways of reading data:

[0047] The first reading method: Use the external acquisition component 500 to connect to the OBD port, and conduct the diagnosis of the airbag controller through the central domain controller to read the corresponding data, mainly using the 2F instruction to simulate a non-locked event.

[0048] The second reading method: Since the airbag controller is a sample with a high functional safety level, the peripheral front collision sensor is collided at the same time, and the vehicle collision signal is detected by the airbag controller and the collision sensor, and the severity of the collision is identified by the system calibration conditions. When the detonation threshold crosses the calibration threshold line set by the detonation algorithm, the bus CrashOutputSt collision signal is triggered and sent. The whole vehicle will show high voltage power down, fuel cut-off, double flash and other operations. Since the peripheral load device 200 designed in the embodiment of the present application isolates the peripheral ignition circuit, the airbag of the whole vehicle will not detonate at this time, but the airbag controller realizes the recording and reading of the collision data at the same time.

[0049] Furthermore, by reading the collision data of the external acquisition component 500, the collision data of the central domain controller 400 and the collision data of the target cloud 700, after analysis and data comparison, the feasibility and effectiveness of the collision data acquisition system of the embodiment of the present application are verified.

[0050] In order to enable those skilled in the art to further understand the collision simulation system of the embodiment of the present application, the following is a detailed description in conjunction with specific embodiments. Figure 4 shown.

[0051] In the event of a collision detonation event, such as a conventional head-on collision, side collision, rear collision, and rollover, and the entire vehicle is not powered off, the airbag system detects the vehicle collision signal through the airbag controller and collision sensor, and identifies the severity of the collision through the system calibration conditions. When the detonation threshold crosses the calibration threshold line set by the detonation algorithm, it triggers the sending of the bus CrashOutputSt collision signal. The airbag controller will send an ignition current to detonate the peripheral load device, and simultaneously record the vehicle speed, acceleration and other information, and simultaneously send the CANFD bus CRO and the hard-line flipped PWM CRO.

[0052] Furthermore, after receiving the CRO, the central domain controller will call the diagnostic component and issue a diagnostic instruction service to read the data from the airbag controller. Among them, the data that needs to be uploaded and read after the collision, such as bus data, SOA service data, etc., are all triggered and collected when PostCrashMode|CrashOutputSt is received for the first time (the same is true for multiple collisions), which is consistent with the first time the diagnostic reading is made. The central domain controller will not jump after receiving the collision signal, so the reading is performed within one power-on cycle. If the power is cut off due to a severe accident caused by a collision of the entire vehicle or due to poor contact during the reading process, the unuploaded part will be read again at the next power-on.

[0053] Furthermore, the central domain controller packages the read collision data and uploads it to the cloud using the on-board communication component T-BOX. The target cloud saves the uploaded collision data to the target cloud, and simultaneously triggers a signal based on the received collision data to perform an alarm prompt function. It also uses the target cloud's automatic analysis tool or local analysis tool to parse the received collision data to generate a viewable target readable report.

[0054] Beneficial effects of the embodiments of the present application:

[0055] (1) It can realize functions such as automatic reading, uploading, and warning of vehicle collision data, which is convenient for early analysis of after-sales data and subsequent expansion of rescue, and provides data accumulation for subsequent collision condition optimization;

[0056] (2) By using the central domain controller, when the vehicle crashes and loses power in some extreme working conditions such as high-speed and harsh conditions, data can be read and uploaded in the next power-on cycle after power is restored, thus optimizing the pain points of some current working conditions and improving the robustness against harsh working conditions.

[0057] (3) It can realize more than 3 event readings, optimizing the situation of manual on-site data reading with diagnostic equipment;

[0058] (4) There is no need to use the actual collision of the whole vehicle to verify the system. When the airbag controller has not been detonated, it can be verified by operating only the airbag controller and using the diagnostic 2F instruction to upload data of non-detonation events. When the airbag control is detonated, multiple event triggers can be performed to simultaneously stimulate the peripheral collision sensor and the airbag controller to the peripheral load to perform the airbag detonation operation. Since the designed adapter board connector is connected to the vehicle's network, there is no need to worry about the detonation of the vehicle's airbag, and the vehicle test environment is relatively efficient.

[0059] According to the collision data acquisition system proposed in the embodiment of the present application, at least one detection component detects the current collision data of the vehicle, and the control component records the current collision data when the current collision data meets the preset airbag detonation conditions, and generates a detonation signal at the same time, so that the peripheral load device simulates the detonation of the airbag according to the detonation signal, isolates the detonation of the airbag of the vehicle, and reads the current collision data recorded by the control component through the central domain controller. In this way, the current problem that the collection of traffic accident data is mainly based on manual collection by professional technicians, and the timeliness and accuracy of data collection are poor is solved, and the automatic collection and classified storage of traffic accident data can be realized, which improves the accuracy and timeliness of collected accident data.

[0060] An embodiment of the present application also provides a vehicle, which includes a collision data collection system as described in the above embodiment.

[0061] The collision data collection method proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0062] Figure 5 It is a flowchart of the collision data collection method according to an embodiment of the present application.

[0063] like Figure 5 As shown, the collision data collection method includes the following steps:

[0064] In step S501, it is detected whether the vehicle has current collision data.

[0065] In step S502, if the vehicle has current collision data, it is determined whether the current collision data meets the preset airbag deployment conditions.

[0066] In step S503, if the current collision data meets the preset airbag deployment condition, the current collision data is recorded, and a deployment signal is generated according to the current collision data, so that the peripheral load device simulates the deployment of the airbag according to the deployment signal and isolates the deployment of the vehicle's airbag.

[0067] Optionally, in some embodiments, the above-mentioned collision data collection method further includes: sending current collision data and historical collision data of the external collection component to a target cloud; and receiving a test report generated by the target cloud based on the current collision data and the historical collision data.
