Title:
METHOD FOR TIME SYNCHRONIZATION BETWEEN COMMUNICATIONS OF MULTIPLE MAIN DEVICES IN CAN BUS
Document Type and Number:
WIPO Patent Application WO/2021/174784
Kind Code:
A1
Abstract:
The present invention discloses a method for time synchronization between communications of multiple main devices in a CAN bus. Said method does not require an additional time communication bus, the transmission of a time synchronization message and the transmission of a data message are performed uniformly on a physical bus, and the bus is still a multi-master architecture, and can dynamically calculate a time deviation of transmission compensation according to the real-time performance of each transmission, and perform compensation in real time, reducing the waste caused by providing a bus additionally, effectively reducing the cost, removing the dependence on the communication rate, and having a flexible and real-time performance.
