ABSTRACT:
According to the present invention, there is provided a device for controlling a motor vehicle installed with an engine and an automatic transmission during a shift in gear positon in the automatic transmission, the automatic transmission having an input shaft drivingly connected to the engine and an output shaft. In the device, an actual value in a speed ratio is accurately detected and thus monitored during a transient period involving a shift in gear position taking place in the automatic transmission, and a closed loop control is effected based on the actual speed ratio detected.
