[0050] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0051] Example 1

[0052] Figure 1 A flowchart of a vehicle data processing method is provided for an embodiment of the present invention. This embodiment is applicable to scenarios where airbag detonation collision signals are processed. The method can be executed by a vehicle data processing device, which can be implemented in the form of hardware and / or software and can be configured in an electronic device.

[0053] like Figure 1 As shown, the vehicle data processing method includes:

[0054] S101. Monitor in real time whether the vehicle has collided using the vehicle's airbag controller.

[0055] In the embodiments of the present invention, the airbag control unit (ACU) is a core component of a vehicle's airbag system and plays a crucial role in the event of a collision. While the vehicle is in motion, the ACU collects real-time vehicle operating status data (e.g., acceleration data) and body pressure data. Based on this data, the ACU determines whether the vehicle has been involved in a collision.

[0056] Depending on whether the vehicle has been detected to have collided, the state value of the airbag deployment collision signal is collected and stored in step S102 or S103. It will be appreciated that the airbag controller controls and changes the state value of the airbag deployment collision signal to inform the vehicle control system whether a collision has occurred. Therefore, the state value of the airbag deployment collision signal is different when the vehicle has collided or not.

[0057] S102: In response to the vehicle not having a collision, collecting a state value of an airbag detonation collision signal according to a first sampling period, and storing the state value of the airbag detonation collision signal in a newly added target storage space of the airbag controller.

[0058] In an embodiment of the present invention, in order to realize the storage and recording of the status value of the airbag detonation collision signal, a target storage space is added during the design process of the airbag controller, wherein the target storage space is provided by a non-volatile storage unit. It is understandable that a non-volatile storage unit refers to a memory in which the stored data does not disappear after the current is turned off. In this way, by using a non-volatile storage unit to provide a target storage space, it can be ensured that the stored status value of the airbag detonation collision signal will not be lost due to power failure. In addition, it should be noted that the size of the target storage space can be set according to actual needs and is not specifically limited here. For example, the size of the target storage space is 1.2kb.

[0059] In an embodiment of the present invention, the first sampling period is exemplarily 100ms. In response to the vehicle not being involved in a collision, the state value of the airbag detonation collision signal can be collected according to the 100ms sampling period, and the collected state value of the airbag detonation collision signal can be stored in a target storage space newly added to the airbag controller. In a specific implementation, the storage location of the state value of the airbag detonation collision signal can be pre-specified as the target storage space in the control program of the pre-designated airbag controller. In this way, after the state value of the airbag detonation collision signal is collected, it can be directly stored in the target storage space. This achieves the storage and recording of the state value of the airbag detonation collision signal.

[0060] Furthermore, in response to the amount of airbag deployment collision signal status values ​​collected and stored during the first sampling period reaching a preset threshold, the target storage space is updated, for example, by overwriting earlier stored data with later stored data or directly deleting earlier stored data in the target storage space. By timely updating the data in the target storage space, the stored data is prevented from exceeding the target storage space limit. For example, the target storage space is updated after 300ms of airbag deployment collision signal status values ​​have been stored in the target storage space.

[0061] S103 . In response to a collision of the vehicle, collect a state value of an airbag detonation collision signal according to a second sampling period, and store the state value of the airbag detonation collision signal in a newly added target storage space of the airbag controller.

[0062] In an embodiment of the present invention, the second sampling period is shorter than the first sampling period. For example, the second sampling period may be 10ms. It is understood that the purpose of collecting the status value of the airbag deployment collision signal during a vehicle collision according to the second sampling period is to more quickly trigger vehicle door unlocking and power and fuel shutoff based on the collected status value of the airbag deployment collision signal during a vehicle collision. The status value of the airbag deployment collision signal collected according to the second sampling period is simultaneously stored in the newly added target storage space of the airbag controller.

[0063] Further, in response to the data amount of the state value of the airbag ignition collision signal collected and stored according to the second sampling period reaching a preset number threshold, the data is stopped from being stored to the target storage space. For example, after the state value of the airbag ignition collision signal is stored for 300 ms, the data can be stopped from being stored to the target storage space.

[0064] It should be noted that, in the prior art, the state value of the airbag ignition collision signal is not stored, so that after the vehicle collision, the real reason for causing the vehicle to catch fire and the door to be locked cannot be determined based on the state value of the airbag ignition collision signal, that is, whether the vehicle triggers the door unlocking and the power and oil circuit breaking in time according to the state value of the airbag ignition collision signal cannot be determined. On the contrary, in the design of the safety airbag controller, a target storage space is specially added, and the state value of the airbag ignition collision signal can be collected and stored according to the real-time monitored collision result, so as to analyze the vehicle collision event in the future.

[0065] S104, in response to the received diagnostic request, the state value of the airbag ignition collision signal stored in the target storage space is sent to the diagnostic device, so that the diagnostic device analyzes the vehicle collision event according to the state value of the airbag ignition collision signal.

[0066] In the embodiment of the application, the diagnostic request is sent by the diagnostic device to the safety airbag controller through a diagnostic service, and the diagnostic service is, for example, the 22 service in the Unified Diagnostic Services (UDS) specified in ISO 14229. In the embodiment of the application, the diagnostic request sent by the diagnostic service at least includes a data identifier. On this basis, the safety airbag controller sends the state value of the airbag ignition collision signal stored in the target storage space to the diagnostic device, including: determining the address of the target storage space according to the data identifier included in the diagnostic request and combining the predetermined mapping relationship between the data identifier and the address of the target storage space; the safety airbag controller acquires the state value of the airbag ignition collision signal from the target storage space according to the address of the target storage space and sends it to the diagnostic device, so that the diagnostic device analyzes the vehicle collision event according to the state value of the airbag ignition collision signal. For example, whether the door is locked and the vehicle catches fire after the collision because the door unlocking and the power and oil circuit breaking are not triggered in time according to the state value of the airbag ignition collision signal is analyzed and judged; if yes, the safety airbag control system can be further optimized; if not, the real reason for causing the door to be locked and the vehicle to catch fire is further analyzed, and then the vehicle is designed according to the real reason, so as to ensure the safety of the vehicle.

[0067] The technical solution of an embodiment of the present invention is to add a target storage space in the airbag controller, and store the collected status value of the airbag detonation collision signal in the target storage space. Subsequently, based on the status value of the airbag detonation collision signal stored in the target storage space, it can be analyzed to determine whether the failure of the status value of the airbag detonation collision signal to trigger automatic unlocking of the vehicle door and power and oil line disconnection in time leads to fire and locking of the vehicle door during a vehicle collision.

[0068] Example 2

[0069] Figure 2 A flow chart of a vehicle data processing method is provided for an embodiment of the present invention. Figure 2 , the method comprises the following steps:

[0070] S201. Monitor in real time whether the vehicle has collided using the vehicle's airbag controller.

[0071] S202. In response to the vehicle not having a collision, the state value of the airbag detonation collision signal is collected according to a first sampling period, and a data identifier is assigned to the collected state value of the airbag detonation collision signal; based on the data identifier associated with the state value of the airbag detonation collision signal, combined with a predetermined mapping relationship between the data identifier and the target storage space, the state value of the airbag detonation collision signal is stored in a target storage space newly added to the airbag controller.

[0072] S203. In response to a collision of the vehicle, the state value of the airbag detonation collision signal is collected according to a second sampling period, and a data identifier is assigned to the collected state value of the airbag detonation collision signal; based on the data identifier associated with the state value of the airbag detonation collision signal, combined with a predetermined mapping relationship between the data identifier and the target storage space, the state value of the airbag detonation collision signal is stored in a target storage space newly added to the airbag controller.

[0073] In an embodiment of the present invention, in addition to specifying the storage location of the status value of the airbag detonation collision signal as the target storage space in the control program of the airbag controller, a mapping relationship between a determined data identifier and the target storage space can also be established in advance. Subsequently, regardless of whether the status value of the airbag detonation collision signal is collected and stored according to the first sampling period or the status value of the airbag detonation collision signal is collected and stored according to the second sampling period, as long as the status value of the airbag detonation collision signal is collected, a data identifier is assigned to the collected status value of the airbag detonation collision signal; subsequently, the airbag controller only needs to know the location where the status value of the airbag detonation collision signal is to be stored based on the mapping relationship between the data identifier and the target storage space, and then perform data storage.

[0074] It can be understood that the state value of the airbag triggering crash signal is stored in this way, considering that if the storage space of the state value of the airbag triggering crash signal is changed later, only the mapping relationship needs to be modified, and the control program of the safety airbag does not need to be modified, so that the efficiency of changing the storage space is higher.

[0075] S204, in response to the received diagnostic request, sending the state value of the airbag triggering crash signal stored in the target storage space to the diagnostic device, so that the diagnostic device analyzes the vehicle crash event according to the state value of the airbag triggering crash signal.

[0076] In the embodiment of the application, a target storage space is added in the safety airbag controller, and the collected state value of the airbag triggering crash signal is stored in the target storage space, so as to facilitate subsequent vehicle crash analysis according to the stored state value of the airbag triggering crash signal.
