The control system includes a stop state detector which detects the vehicle stopped state when the forward driving range is selected, the accelerator pedal is released and the brake pedal is depressed. The control system further includes a clutch disengaging system which provides a neutral control, and a brake engaging system which provides a hill-hold control and performs a neutral control with the engine not under a load.
