The embodiment of the present invention is applicable to the case of collecting signal data of a vehicle controller configured in a vehicle. The method can be executed by a vehicle controller data acquisition device, which can be implemented in the form of hardware and / or software and can be configured in a vehicle device that implements the vehicle controller data acquisition method. Figure 1 As shown, the vehicle controller data acquisition method includes:
[0026] S101. For each regional controller of a target vehicle, first data is collected based on a first data collection node deployed in the regional controller. The regional controller is associated with at least one sub-controller of the target vehicle. The first data includes signal data of each sub-controller associated with the regional controller.
[0027] Among them, the target vehicle may refer to a vehicle that adopts a centralized and domain-controlled electronic and electrical architecture. The target vehicle is equipped with a central domain controller and at least one regional controller. The central domain controller may refer to the top-level control unit in the target vehicle. The central domain controller can realize centralized management and decision-making of the core functions of the vehicle by integrating the signal data of the regional controllers. The regional controller may refer to a control unit divided according to the physical area of the target vehicle. The regional controller can be used to manage the sub-controllers associated in the physical area. The sub-controller may refer to the control unit in the target vehicle that is responsible for a single or specific function. The sub-controller can realize the corresponding function by connecting to sensors or actuators. Signal data may refer to electrical signals or digital information that are processed, transmitted and responded by the vehicle controller in the target vehicle.
[0028] The data acquisition node may refer to a node used to collect vehicle controller signal data in the target vehicle in real time. Figure 2 A first data acquisition node is pre-deployed in each regional controller of the target vehicle, so that the signal data of each sub-controller associated with the regional controller can be collected in real time through the first data acquisition node, and the signal data of each sub-controller associated with the regional controller can be aggregated to obtain the first data.
[0029] Exemplarily, the target vehicle's regional controllers may include at least a cabin regional controller, a body regional controller, a chassis and power regional controller, and a battery and energy regional controller. The body regional controller may be associated with at least a door sub-controller, a window sub-controller, and a lighting sub-controller.
[0030] As an optional implementation of the embodiment of the present invention, the first data collection node deployed based on the regional controller collects the first data, including the following steps A1-A3:
[0031] Step A1: For each sub-controller associated with the regional controller, the first data acquisition node collects CAN messages sent by the sub-controller associated with the regional controller based on the CAN communication protocol stack, or collects LIN messages sent by the sub-controller associated with the regional controller based on the LIN communication protocol stack.
[0032] Step A2: determining signal data of the sub-controller associated with the regional controller based on the CAN message or LIN message sent by the sub-controller associated with the regional controller.
[0033] Step A3: Determine first data based on signal data of each sub-controller associated with the regional controller.
[0034] Among them, the communication protocol stack may refer to a set of communication protocols divided into a hierarchical structure. The communication protocol stack can realize data transmission and communication functions through the communication protocols of each layer. The CAN (Controller Area Network) communication protocol stack may refer to a communication protocol stack for CAN bus communication. The LIN (Local Interconnect Network) communication protocol stack may refer to a communication protocol stack for LIN bus communication. The CAN communication protocol stack and the LIN communication protocol stack can realize data communication between vehicle controllers in the target vehicle. The CAN message may refer to a communication data unit that complies with the CAN communication protocol. The LIN message may refer to a communication data unit that complies with the LIN communication protocol.
[0035] Specifically, refer to Figure 2 The first data collection node deployed in the regional controller can collect CAN messages sent by the sub-controller associated with the regional controller from the CAN bus corresponding to the regional controller, or collect LIN messages sent by the sub-controller associated with the regional controller from the LIN bus corresponding to the regional controller. Furthermore, signal data of the sub-controller associated with the regional controller can be obtained from the CAN messages or LIN messages sent by the sub-controller associated with the regional controller.
[0036] Optionally, the signal data of each sub-controller associated with the regional controller is aggregated and encapsulated into an Ethernet message as the first data. The effective byte length of an Ethernet message is much longer than that of a CAN message or a LIN message, and can accommodate more signal data. The first data is represented in the form of an Ethernet message, so that the first data acquisition node can transmit the first data based on the Ethernet communication protocol stack.
[0037] As an optional implementation manner of an embodiment of the present invention, determining signal data of a sub-controller associated with a regional controller based on a CAN message or a LIN message sent by the sub-controller associated with the regional controller includes: removing first information contained in the CAN message or the LIN message sent by the sub-controller associated with the regional controller to obtain the signal data of the sub-controller associated with the regional controller, wherein the first information is information unrelated to the signal data.
[0038] The first information may refer to an invalid message contained in a CAN message or a LIN message. The first information may include at least: the start information, control information, check information and end information of the message. Figure 2 The first data acquisition node can unpack the CAN message sent by the sub-controller associated with the regional controller based on the CAN communication protocol stack, and remove the first information contained in the CAN message sent by the sub-controller associated with the regional controller; or the first data acquisition node can unpack the LIN message sent by the sub-controller associated with the regional controller based on the LIN communication protocol stack, and remove the first information contained in the LIN message sent by the sub-controller associated with the regional controller, thereby obtaining the signal data of the sub-controller associated with the regional controller, so as to improve the validity of the sub-controller signal data.
[0039] S102. A second data collection node deployed based on the central domain controller of the target vehicle collects second data, where the second data includes signal data of the central domain controller, signal data of each regional controller, and first data collected by each first data collection node.
[0040] Specifically, refer to Figure 2 The target vehicle's central domain controller is pre-deployed with a second data collection node. This node collects the central domain controller's signal data, the signal data from each regional controller, and the first data collected by each first data collection node in real time. The second data is then aggregated to obtain the central domain controller's signal data, the signal data from each regional controller, and each piece of first data.
[0041] S103: Transmit the second data to the vehicle-mounted telematics processing terminal configured for the target vehicle.
[0042] The vehicle-mounted telematics terminal may refer to an on-board intelligent device that integrates communication, computing, and data processing functions in the target vehicle. The target vehicle can at least interact with the cloud through the configured vehicle-mounted telematics terminal. Figure 2The vehicle-mounted telematics processing terminal may be a T-BOX (Telematics Box) terminal. After collecting the second data in real time, the second data collection node may transmit the second data to the vehicle-mounted telematics processing terminal configured in the target vehicle based on the Ethernet communication protocol stack.
[0043] The technical solution of the embodiment of the present invention is to collect first data for each regional controller of the target vehicle based on a first data collection node deployed in the regional controller. The regional controller is associated with at least one sub-controller of the target vehicle. The first data includes signal data of each sub-controller associated with the regional controller, thereby realizing real-time collection of signal data of each sub-controller associated with the regional controller through the first data collection node pre-deployed in each regional controller, thereby improving the collection efficiency of signal data of sub-controllers in the target vehicle; collecting second data based on a second data collection node deployed in a central domain controller of the target vehicle, wherein the second data includes signal data of the central domain controller, signal data of each regional controller and first data collected by each first data collection node, thereby realizing real-time collection of signal data of the central domain controller, signal data of each regional controller and each first data through the second data collection node pre-deployed in the central domain controller, thereby improving the collection efficiency of signal data of each vehicle controller in the target vehicle; and transmitting the second data to the on-board telematics processing terminal configured for the target vehicle.

[0048] The Ethernet communication protocol stack may refer to a communication protocol stack used for Ethernet communication. Figure 2 The second data acquisition node and each first data acquisition node can communicate based on the Ethernet communication protocol stack, so as to improve the efficiency of the second data acquisition node in collecting the first data sent by each first data acquisition node.
[0049] S203: Transmit the second data to the vehicle-mounted telematics terminal configured for the target vehicle.
[0050] S204: Upload the second data to the cloud server for storage via the vehicle-mounted telematics terminal configured for the target vehicle.
[0051] Among them, cloud server can refer to a virtual server based on cloud computing. Cloud computing can centrally manage and dynamically allocate computing resources, data storage and services through the network. Figure 2 , the target vehicle can communicate with the cloud server through the on-board telematics terminal configured for the target vehicle, and send the second data to the cloud server in real time for storage, so as to realize the storage of the signal data generated in real time by each vehicle controller in the target vehicle.
[0052] As an optional implementation of an embodiment of the present invention, before uploading the second data to the cloud server, it also includes: compressing the second data to improve the efficiency of uploading the second data to the cloud server and reduce the storage space occupied by the second data in the cloud server.

[0055] Step B2: parse the second data uploaded at the first moment to obtain signal data of each vehicle controller of the target vehicle at the first moment.
[0056] Step B3: Determine a vehicle controller of the target vehicle that has a fault at the first moment based on the signal data of each vehicle controller of the target vehicle at the first moment.
[0057] The vehicle controller may be a central domain controller, a regional controller, or a sub-controller of the target vehicle. By parsing the second data, signal data of the central domain controller, signal data of each regional controller, and signal data of each sub-controller in the target vehicle can be obtained as signal data of each vehicle controller in the target vehicle.
[0058] Specifically, when a target vehicle breaks down, the moment the breakdown occurs can be recorded as the first moment. Furthermore, by analyzing the signal data of each vehicle controller of the target vehicle at the first moment, fault detection can be performed on each vehicle controller of the target vehicle, thereby locating the vehicle controller of the target vehicle that broke down at the first moment.
[0059] The technical solution of the embodiment of the present invention is to collect first data for each regional controller of the target vehicle based on a first data collection node deployed in the regional controller, the regional controller is associated with at least one sub-controller of the target vehicle, and the first data includes signal data of each sub-controller associated with the regional controller; collect second data based on a second data collection node deployed in the central domain controller of the target vehicle, the second data includes signal data of the central domain controller, signal data of each regional controller and first data collected by each first data collection node, thereby realizing real-time collection of signal data of the central domain controller, signal data of each regional controller and each first data through the second data collection node pre-deployed in the central domain controller, thereby improving the collection efficiency of signal data of each vehicle controller in the target vehicle; transmit the second data to the on-board telematics processing terminal configured for the target vehicle; upload the second data to the cloud server for storage through the on-board telematics processing terminal configured for the target vehicle, thereby realizing storage of signal data generated in real time by each vehicle controller in the target vehicle.
