[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The existing data collection scheme is shown in FIG1 , which specifically involves directly subscribing to the services that need to be collected by each software module through a data collection module, and directly sending the interfaces that need to be collected to the data collection module.

[0036] Since there are multiple software modules with data collection requirements, each software module directly subscribes to the services that need to be collected, resulting in the number of interfaces that need to be collected * the number of data collection modules. If the number of service interfaces that need to be collected is 1000, the number of data collection modules is 3, and the service interface sending cycle is 100ms, 1000*3*10=30,000 messages will be generated per second. The impact of 30,000 surrounding data generated by data collection on the hardware sending load and bandwidth is huge, which is unbearable for the hardware. In addition, the sending cycle of many of the thousands of interface messages is less than 100ms, which may be 5ms, 10ms, or 20ms. If they are subscribed directly, it will cause hardware jamming.

[0037] In order to solve the above problem, in one embodiment, as shown in FIG2 , a vehicle data collection method is provided. This embodiment takes the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0038] S202: Receive a data collection request sent by the vehicle terminal, and determine at least one data collection service based on the data collection request, where each data collection service corresponds to a vehicle data collection module.

[0039] Each data collection service corresponds to a vehicle function, and all vehicle data related to the vehicle function can be collected based on the data collection request.

[0040] S204. For each data collection service, a data collection request is sent to a vehicle data collection module corresponding to the data collection service. Each vehicle data collection module corresponds to at least one data collection submodule, and each data collection submodule is used to collect a type of target data.

[0041] The vehicle data collection module and the data collection sub-module can interact and communicate with each other through the service interface, and the data collection sub-module will encapsulate the service interface to provide a service.

[0042] S206. Receive at least one target data returned by the vehicle data acquisition module.

[0043] The target data is at least one of vehicle sensor data, vehicle status data, driving log, maintenance record, vehicle terminal data, vehicle environment data or vehicle safety data.

[0044] In the above vehicle data collection method, a data collection request sent by a vehicle terminal is received, and at least one data collection service is determined based on the data collection request, and each data collection service corresponds to a vehicle data collection module; for each data collection service, a data collection request is sent to the vehicle data collection module corresponding to the data collection service, and each vehicle data collection module corresponds to at least one data collection submodule, and each data collection submodule is used to collect a type of target data; and at least one type of target data returned by the vehicle data collection module is received. The method provided in the present application can reduce the load of the entire vehicle and reduce the consumption of hardware while obtaining vehicle data.

[0045] In some embodiments, there is a service interface between each data collection submodule and the corresponding vehicle data collection module, and the target data is sent from the data collection submodule to the vehicle data collection module through the service interface.

[0046] Among them, the service interface is used for interaction and communication between the data acquisition submodule and the vehicle data acquisition module.

[0047] In some embodiments, as shown in FIG3 , the data acquisition submodule corresponds to the regional controller on the vehicle one by one; before receiving at least one target data returned by the vehicle data acquisition module, the method includes:

[0048] S302: When the vehicle data collection module successfully subscribes to the service of the regional controller corresponding to the data collection submodule, the data type corresponding to the target data is obtained based on the service interface corresponding to the data collection submodule.

[0049] S304: Based on the data type, control the vehicle data acquisition module to receive the target data sent by the data acquisition submodule.

[0050] Before collecting data, the vehicle data collection module will first confirm the regional controller where the data is to be collected and subscribe to the service of the regional controller. Then, it can obtain the required collected data through the data type referenced by the service interface element of the data collection submodule.

[0051] In this embodiment, target data is acquired based on the data type, so that the acquired target data is more accurate.

[0052] In some embodiments, the process of the data acquisition submodule sending data to the vehicle data acquisition module is periodic, and different data acquisition submodules have different corresponding periods.

[0053] For example, the period may be 5 ms, 10 ms, 50 ms or 100 ms.

[0054] In some embodiments, after receiving at least one target data returned by the vehicle data acquisition module, it includes: obtaining the current state of the vehicle based on the target data; when the current state is an abnormal state, displaying the target data and the current state on the display screen of the vehicle terminal, and controlling the vehicle terminal to issue an alarm message.

[0055] Among them, the alarm information can be a specific alarm sound or an alarm screen displayed on a display screen, and the embodiment of the present application does not make specific limitations on this.

[0056] In this embodiment, when the current state is an abnormal state, an alarm message is issued to ensure the safety of the vehicle during driving.

[0057] In some embodiments, the target data is at least one of vehicle sensor data, vehicle status data, driving log, maintenance record, vehicle terminal data, vehicle environment data, or vehicle safety data.

[0058] Among them, the sensor can be a voltage sensor, a vehicle speed sensor, a fuel temperature sensor and a coolant sensor, and the sensor can also be other sensors, which is not specifically limited in the embodiments of the present application.

[0059] In one embodiment, as shown in FIG4 , another vehicle data collection method is provided. The method includes the following contents:

[0060] (1) Establish several data acquisition sub-modules. The principle of establishing sub-modules is based on the regional controller with physical chips. That is, there is a regional controller with a chip and a sub-module.

[0061] (2) In the acquisition module, the service interface that needs to be collected on its own chip (the service interface provided by the data acquisition module 1 and the collected data module 2 is the collected service interface. The period of the service interface provided by each collected module is not the same. For example, there may be 5ms, 10ms, 50ms, 100ms, etc.) is the service interface it receives. The sub-acquisition module encapsulates these interfaces and provides a service.

[0062] (3) The interface principle of the sub-acquisition module encapsulation service can be differentiated according to the data acquisition business, which can be divided into periodic sending interface and non-periodic sending interface. The period can be determined according to the specific acquisition requirements (such as 100ms, 500ms). This process can also reduce the bus load.

[0063] (4) When the data collection module collects data, it first confirms the regional controller where the data is to be collected and subscribes to the service of the regional controller. It can then obtain the required collection data through the data type referenced by the sub-collection service interface element.

[0064] Taking VDC_MCU as an example, the service interface encapsulation process is shown in Figure 5:

[0065] (1) On the MCU chip of the regional controller VDC, there are multiple data items that need to be collected (as shown in green), and the multiple data items that need to be collected are located on each software module (Software Component), as shown in the figure below, window (Window SWC), sunroof (Roof SWC), high beam (HighBeam SWC), position light (PositionLight SWC), turn signal (TurnLight SWC), brake light (BrakeLight SWC), seat heating (SeatHeat SWC), etc.

[0066] (2) Establish a sub-collection software module (sub-collection VDC_MCU_SWC). The sub-collection module receives each service interface that needs to be collected, encapsulates it, and packages it into a structure data type to provide it with the collected service interface.

[0067] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
