[0051] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0052] Embodiment 1

[0053] 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. The vehicle data processing device can be configured in an electronic device.

[0054] like Figure 1 As shown, the vehicle data processing method includes:

[0055] S101. Monitor in real time whether the vehicle has collided by using the airbag controller of the vehicle.

[0056] In the embodiment of the present invention, the airbag controller (Airbag Control Unit, ACU for short) is the core component of the automobile airbag system, which plays a vital role when the vehicle collides. During the driving process of the vehicle, the airbag controller can collect the vehicle's operating status data (such as the vehicle's acceleration data) and body pressure data in real time, and then determine whether the vehicle collides based on the collected vehicle's operating status data and body pressure data.

[0057] According to whether the monitored vehicle has collided, the state value of the airbag detonation collision signal is collected and stored according to step S102 or step S103. It can be understood that the airbag controller prompts the vehicle control system whether a collision has occurred by controlling and changing the state value of the airbag detonation collision signal. Therefore, the state value of the airbag detonation collision signal is different when the vehicle has collided or not.

[0058] 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 target storage space newly added by the airbag controller.

[0059] In an embodiment of the present invention, in order to realize the storage record of the state value of the airbag detonation collision signal, a target storage space is added in the design process of the airbag controller, wherein the target storage space is provided by a non-volatile storage unit. It can be understood 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 state value of the stored 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. Exemplarily, the size of the target storage space is 1.2kb.

[0060] In the embodiment of the present invention, the first sampling period is exemplarily 100ms. In response to the vehicle not colliding, the state value of the airbag detonation collision signal can be collected according to the sampling period of 100ms, and the collected state value of the airbag detonation collision signal can be stored in the newly added target storage space of the airbag controller. In the specific implementation, the storage location of the state value of the airbag detonation collision signal can be specified as the target storage space in the control program of the airbag controller in advance. 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. In this way, the storage record of the state value of the airbag detonation collision signal is realized.

[0061] Furthermore, in response to the data amount of the state value of the airbag detonation collision signal collected and stored according to the first sampling period reaching a preset quantity threshold, the target storage space is updated, for example, the previously stored data is overwritten with the later stored data, or the previously stored data in the target storage space is directly deleted. By timely updating the data in the target storage space, it is prevented that the stored data exceeds the target storage space limit. Exemplarily, the target storage space is updated as long as the state value of the airbag detonation collision signal for 300ms is stored in the target storage space.

[0062] S103: In response to a collision of the vehicle, collecting a state value of an airbag detonation collision signal according to a second sampling period, and storing the state value of the airbag detonation collision signal in a target storage space newly added by the airbag controller.

[0063] In the embodiment of the present invention, the second sampling period is less than the first sampling period. For example, the second sampling period may be 10ms. It is understandable that the reason for collecting the state value of the airbag detonation collision signal when the vehicle collides according to the second sampling period is to be able to trigger the unlocking of the vehicle door and the cutting off of the power and oil circuit more quickly according to the state value of the airbag detonation collision signal collected when the vehicle collides. The state value of the airbag detonation collision signal collected according to the second sampling period will be stored in the newly added target storage space of the safety airbag controller at the same time.

[0064] Further, in response to the amount of data of the state value of the airbag detonation collision signal collected and stored according to the second sampling period reaching a preset quantity threshold, the storage of data to the target storage space is stopped. Exemplarily, after storing and recording the state value of the airbag detonation collision signal for 300ms, the storage of data to the target storage space can be stopped.

[0065] It should be noted that, in the current prior art, the state value of the airbag detonation collision signal is not stored and recorded, resulting in the inability to determine the real cause of the vehicle fire and the door being locked based on the state value of the airbag detonation collision signal after the vehicle collides, that is, it is impossible to determine whether the vehicle triggers the door unlocking and cuts off the power and oil circuit in time according to the state value of the airbag detonation collision signal. On the contrary, the solution of the present invention adds a special target storage space when designing the airbag controller, and can subsequently collect and save the state value of the airbag detonation collision signal based on the real-time monitoring collision results, so as to conduct subsequent vehicle collision event analysis.

[0066] S104. In response to the received diagnosis request, the state value of the airbag detonation collision signal stored in the target storage space is sent to the diagnosis device, so that the diagnosis device performs vehicle collision event analysis according to the state value of the airbag detonation collision signal.

[0067] In an embodiment of the present invention, a diagnostic request is sent by a diagnostic device to an airbag controller through a diagnostic service. An exemplary diagnostic service may be service 22 in the Unified Diagnostic Services (UDS) specified in ISO 14229. In an embodiment of the present invention, the diagnostic request sent by the diagnostic service at least includes a data identifier. On this basis, the airbag controller sends the status value of the airbag detonation 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 in combination with a predetermined mapping relationship between the data identifier and the address of the target storage space; the airbag controller obtains the status value of the airbag detonation 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 performs vehicle collision event analysis according to the status value of the airbag detonation collision signal. For example, it can be analyzed to determine whether the door was locked and caught fire after a vehicle collision because the door unlocking, power and oil circuit were not cut off in time according to the status value of the airbag detonation collision signal; if so, the airbag control system can be further optimized; if not, the real cause of the door locking and fire can be further analyzed, and the vehicle design can be optimized based on the real cause to ensure the safety of the vehicle.

[0068] The technical solution of the 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 saved in the target storage space, it can be analyzed to determine whether the status value of the airbag detonation collision signal fails to trigger automatic unlocking of the door and power and oil circuit disconnection in time, resulting in fire and locking of the door during a vehicle collision.

[0069] Embodiment 2

[0070] 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:

[0071] S201. Monitor in real time whether the vehicle has collided by using the airbag controller of the vehicle.

[0072] 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, in combination 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] 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, in combination 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.

[0074] 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 certain 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.

[0075] It is understandable that the reason why the status value of the airbag detonation collision signal is stored in this way is that if the storage space of the status value of the airbag detonation collision signal needs to be changed later, it is only necessary to modify the mapping relationship, and there is no need to modify the airbag control program, which makes changing the storage space more efficient.

[0076] S204. In response to the received diagnosis request, send the state value of the airbag detonation collision signal stored in the target storage space to the diagnosis device, so that the diagnosis device performs vehicle collision event analysis according to the state value of the airbag detonation collision signal.

[0077] In an embodiment of the present invention, a target storage space is added in the airbag controller, and the state value of the collected airbag detonation collision signal is stored in the target storage space, so as to facilitate subsequent vehicle collision analysis based on the stored state value of the airbag detonation collision signal.
