F-1406 C-3937 PERFORMANCE CONTROL OF A MOTOR VEHICLE ENGINE FOR CONSISTENT HIGH QUALITY TRANSMISSION SHIFTING Abstract of the Disclosure In a motor vehicle power train including an automatic transmission calibrated to provide high quality shifting at a specified engine performance level, an engine spark timing control system effective in the course of transmission shifting for bringing the actual engine acceleration into correspondence with a predefined engine acceleration. The predefined engine acceleration corresponds to the acceleration which would occur at the specified engine performance level upon which the transmission calibration is based. As a result, high quality transmission shifting is achieved despite engine performance level variations.
