CONTROLLING OF AUTOMATIC TRANSMISSION OF VEHICLE

摘要

PURPOSE:To improve drivability by devising a device to carry out non creep control so that the non creep control is continued even when a controller comes to be inoperative after the non creep control is started. CONSTITUTION:An electronic control circuit 10 is programmed to carry out non creep control to up-shift from a first speed to a second speed by way of outputting a second speed signal when actuation of a brake of a car by operation of a brake pedal or a parking lever is confirmed by a signal from a brake switch 13c when a car speed V is lower than s specific value V1 close to zero and throttle opening O is in a territory shown in slanting lines which is lower than a specific opening O1 close to full closing, that is, in the idling drive state when the car actually stops even when a driving state is in a first speed territory when a drive range is selected. It is possible to improve drivability without causing a shock as done by conventional technique which interrupts the non creep control intermittently due to actuation or non-actuation of the brake.
