PURPOSE:To permit efficient power train stop control by a method wherein the stop is controlled so that a technique to maintain the idling revolving number of an engine in an objective value and the technique to maintain creep torque in the objective value are harmonized with each other. CONSTITUTION:A controller 40 reads in a revolving number signal NE from a revolving number sensor 25 for the engine, the rotating number signal NT from a turbine rotating number sensor 26, the revolving number signal NO of an output shaft revolving number sensor 27, the opening degree signal STH of a throttle valve 20 and the signal SL of a range switch 24 corresponding to the range of speed selection in accordance with a program and dicides whether is it vehicle stopping condition or not. In case the vehicle is being stopped, the controller 40 operates a revolving number controlling signal SC of engine idling. In case it is decided that the condition is in the automatic speed change running position (D) of advancing, it is decided that a set period of time has elapsed after changing N D and the controller decides whether the creep torque is an objective value necessary for preventing the creep or not, thus, the creep may be prevented. |
