Abstract

The present invention provides a CAN channel connection device identification method, a data transmission method, and a system. The CAN channel connection device identification method includes: obtaining the device message data and preset information of the CAN device currently connected to each CAN channel one by one. Device characteristic configuration information; based on the ID information in the device message data, determine the device identification of the CAN device corresponding to each CAN channel from the preset device characteristic configuration information; based on each CAN channel and the device identification of the corresponding CAN device, establish Current device maintenance list. By implementing the invention, the flexibility of equipment access and test efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a CAN channel connection device identification method, a data transmission method, and a system. Background technique [0002] When the current automotive CAN transmission type devices (including CAN interface sensors, vehicle chassis equipment, etc.) are connected to the computing platform, the corresponding CAN channel will be specified for each CAN device. When connecting the system, the CAN device needs to be connected to the specified CAN channel, and the computing center reads the corresponding device data from the specified CAN channel. [0003] The existing CAN device access method needs to be connected strictly according to the channel configuration. With the increase of CAN devices, the complexity of the connection operation is getting higher and higher. Engineers need to spend a lot of energy to match CAN devices and CAN channels. Work. Moreover, when adapt...
