摘要:
The present invention provides an apparatus and a method for controlling an automatic transmission of a motor vehicle having an engine and an automatic transmission including a clutch with an actuator for changing gear position comprising a detecting means for detecting a completion of the gear change and a signal generating means for generating a control signal to the actuator for applying continued pressure to the clutch for a predetermined time after the detection means detects the completion of the gear change.
摘要:
A shift control system for an automatic transmission having an automatic shift mode in which a proper gear ratio is automatically selected according to a shift command based on a throttle valve opening and a vehicle speed, and further having a manual shift mode in which a gear ratio is selected according to a shift command given by driver's manual operation. The shift control system includes timer means for counting an elapsed time after a shift operation has been started. The elapsed time is compared with a predetermined first re-shift permission time in the case of automatic shift operation and with a predetermined second re-shift permission time in the case of manual shift operation. The first re-shift permission time and the second re-shift permission time are different from each other to optimize the shift control both in the automatic shift mode and in the manual shift mode.

A driving force control system for an automotive vehicle comprises an ordinary target driving force generator. It determines an ordinary target driving force in response to operator manipulation of the accelerator pedal and vehicle speed. The ordinary target driving force is a predetermined target value of driving force required to keep the vehicle rolling over the surface of a flat road that has 0% gradient. A running resistance increment generator determines an increment in running resistance from a standard resistance that is predetermined for the vehicle. A corrected target driving force generator receives the ordinary target driving force, the vehicle speed and the running resistance increment. It determines corrected target driving force. The corrected target driving force generator restrains the corrected target driving force in response to idle and brake signals from an idle switch and a brake switch.

An automatic transmission controller is capable of compensating for both driver type and tendencies of a driver in temporary acceleration, such as in passing. The automatic transmission controller executes a driver type judging subroutine for judging the overall acceleration habits of the driver and classifying the driver as one of a plurality of driver types by monitoring the driving behavior for a predetermined time. The controller also executes a temporary acceleration inclination judging routine for judging the habits of the driver in temporary acceleration by monitoring driving behavior for a period of time shorter than the predetermined time, and executes shift control routines for controlling and changing the shift timing based on the judged driver type and the inclination in temporary acceleration. The controller controls shift timing, taking into account both the driver type and the inclination in temporary acceleration, such as passing.

A control system for an engine-CVT powertrain controls the target driving force during traveling on a ramp to meet operator power demand and/or the target input speed of the CVT to accomplish the ramp target window during traveling on the ramp to meet operator deceleration command.
