[0047] see figure 1 .

[0048] Such as figure 1 As shown, this embodiment provides a vehicle data transmission method, at least including the following steps:

[0049] S1. Filter the CAN message according to the pre-configured CAN ID list, and detect whether the CAN message in the data packet meets the preset message condition;

[0050] S2. When it is detected that the CAN message satisfies the preset message condition, fill the CAN message into the data buffer until receiving all the CAN messages that meet the preset message condition in the current round of transmission;

[0051] S3. Through the AP node, all the CAN messages that meet the preset message conditions received in this round are packaged into data packets to obtain corresponding TCP data packets;

[0052] S4. Confirm that the TCP connection is established, and send the TCP data packet to the ROS2 node;

[0053] S5. Perform data processing on the TCP data packet by the ROS2 node to generate a CAN data packet. ...

no. 2 example

[0087] see figure 2 .

[0088] Such as figure 2 As shown, this embodiment provides a vehicle data transmission device, including:

[0089] The message filtering module 100 is configured to filter CAN messages according to a pre-configured CAN ID list, and detect whether the CAN messages in the data packet meet preset message conditions.

[0090] For the message filtering module 100, after receiving the CAN (Controller Area Network, controller area network) message at the MCU (Microcontroller Unit, micro control unit), the CAN message is processed according to the CAN ID list configured in advance by the user. Filtering, by performing format detection on the CAN message in the received data packet, including CAN ID and CAN Channel.

[0091] The message receiving module 200 is used to fill the CAN message into the data buffer when it is detected that the CAN message meets the preset message condition, until receiving all the CAN messages that meet the preset message conditi...

Abstract

The invention discloses a vehicle data transmission method, device and equipment and a medium, and the method comprises the steps: filtering a CAN message according to a pre-configured CAN ID list, and detecting whether the CAN message in a data packet meets a preset message condition or not; when it is detected that the CAN message meets a preset message condition, filling the CAN message into a data buffer until all CAN messages meeting the preset message condition in the current transmission are received; carrying out data packing on all CAN messages which meet a preset message condition and are received in the round through the AP node to obtain a corresponding TCP data packet; confirming to establish TCP connection, and sending the TCP data packet to the ROS2 node; and performing data processing on the TCP data packet through the ROS2 node to generate a CAN data packet. According to the invention, through configuration of the AP nodes, data transmission between vehicles is realized, the configuration of vehicle channels is effectively improved, and the reliability and expansibility of data paths are ensured.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a vehicle data transmission method, device, equipment and medium. Background technique [0002] With the development of automobile technology, autonomous driving, as the main direction of intelligent and networked development in the field of global vehicles and transportation travel, will have important value in future transportation. At present, autonomous driving vehicles have begun to become an important part of people's travel. tool. In the automotive field, a vehicle's Microcontroller Unit (MCU) can acquire data collected by sensors, cameras, and a vehicle VCU (Vehicle Control Unit, vehicle controller). [0003] However, in the process of research and practice of the prior art, the inventors of the present invention found that the existing vehicle data transmission mode is relatively fixed and single, resulting in low scalability of the communication mode be...
