| Abstract: | A CAN bus interface technology used in an automatic transmission bench test was introduced.Based on the bench test of electronic automatic transmission,CAN bus hardware circuit was designed,which used the Motorola corporation 32-bit microprocessors MC68376 as the central processing unit.According to standard CAN bus eommunieatlon protocol,the CAN bus software receive/send were programmed and designed.The data communication between CAN bus nodes was realized on the bench test,The shifting course of automatic transmission was analyzed through CAN data collection, and the integration control of engine and automatic transmission was realized by adjusting the speed, therefore the shifting quality was improved. |
