SYSTEM ZUR STEUERUNG EINER AUTOMATISCHEN GETRIEBEEINRICHTUNG VON FAHRZEUGEN

摘要

In an automatic transmission system for a vehicle having a gear transmission and a clutch which are electronically controlled by a control unit, the system includes a discrimination unit for discriminating whether or not the vehicle is running with the gear transmission shifted to its neutral position and a determining unit for determining a target gear position to which the gear transmission is to be shifted in the case where the vehicle is running without fuel-combustion in the engine. The control unit is caused to control the gear transmission to shift to the target gear position and the clutch to engage in response to the discrimination unit when an ignition switch is turned to its OFF position in the case where the vehicle is running with the gear transmission shifted to the neutral position, whereby the rotational torque of wheels can be transmitted through the automatic transmission system to the engine. As a result, the rotating of the engine is assured even if the ignition switch is turned to its OFF position to stop the fuel combustion in the engine.
