Canbus communication system and retry control method

Abstract

A controller area network bus (CANBUS) communication system and a retry control method are provided. The retry control method includes: setting a preset number of transmissions and a retransmission strategy through a first device, the retransmission strategy includes a plurality of transmission times and a plurality of timeout intervals corresponding to the plurality of transmission times, and the plurality of timeout intervals are all different; transmitting a transmission request to a second device through a second device through the first device; determining whether a reply corresponding to the transmission request is received within a current timeout interval corresponding to a current number of transmissions based on the retransmission strategy through the first device; in response to not receiving the reply within the current timeout interval, determining through the first device whether the current number of transmissions is less than the preset number of transmissions; and in response to the current number of transmissions being less than the preset number of transmissions, retransmitting the transmission request to the second device through the first device.
