Title: Synchronous control method and device for internal combustion engine
Inventor: KAMIJO YUSUKE
IPC: F02D41/06
Filed: 2001-06-15
Abstract: PROBLEM TO BE SOLVED: To suppress shock by performing another processing at proper timing in the stop and start of the output of an internal combustion engine even in a case when the delay exists in transmitting the information on the stop of the fuel feed or the start of the fuel feed. SOLUTION: The timing of the stop of the combustion feed and the start of the combustion feed performed by an engine ECU is limited to an intake top dead center, when the generation and extinction of the driving force are synchronized between an engine and M/G. The timing in starting and stopping the driving of the M/G performed by a motor ECU after the acquirement of the information on the stop and the start of the combustion feed, is determined to be counted from the intake top dead center thereafter (S230, S240). Accordingly, in counting to the timing of the start and stop of the driving of the M/G (S250, S260), the delay in the communication of the data can be compensated only by considering the delay between the top dead centers, and the above purpose can be attained.
