Automobile-based variable parallel communication method, equipment and medium

Abstract

The invention provides an automobile-based variable parallel communication method. The method comprises the steps: message data is acquired, wherein the message data sent by a transmission ECU in an automobile CAN communication system is acquired; the data length of the message data is counted, the number of bit digits is obtained, and the number of the bit digits is taken as the number of neededcommunication channels; data content in the message data is marked according to a preset data position order to obtain marked message data; and communication channels with the same number as the needed communication channels are selected randomly, the marked message data is transmitted to a target ECU through the needed communication channels in parallel, and the target ECU conducts integration processing on the marked message data according to the preset data position order. According to the automobile-based variable parallel communication method, high-speed point-to-point data transmission is achieved, the timeliness and the examinability of the data are improved, therefore, the message data is transmitted at high speed, data queueing delay does not exist, and checking is easy.

Description

technical field [0001] The invention relates to the field of automobile communication, in particular to an automobile-based variable parallel communication control method, equipment and medium. Background technique [0002] At present, the communication method used in automobiles usually uses CAN serial communication with a hard line or twisted pair, which is the communication method for the transmission of the established serial channel. The former can only transmit pulse signals, which is relatively simple; the latter realizes message (AB 8B ...) transmission through a series of serial binary 0101, which is suitable for vehicle network, but the process is complicated, requires a CAN transceiver and is difficult to troubleshoot. In addition, the above two methods transmit the message signal in the automobile communication through the existing communication channel through the serial communication method, and the number of channels cannot be reasonably selected according to ...
