Kick down control method for five speed automatic motor vehicle gearbox uses double phase gear change with secondary phase if kick down control signal is received

摘要

The kick down control method for a five speed motor vehicle gearbox involves receiving a signal to change down from fifth to third or second and operating a gearshift. This moves from fifth to fourth by operating an actuator in a secondary gear change phase if the signal for fifth to third or second is received. The start point of the control phase is defined at the outlet side of the primary gear change phase and followed through.
