Abstract
A control system, which creates a neutral condition if a vehicle is stationary with the brake of the vehicle being actuated and the accelerator for the engine being turned off while the transmission is set in a drive range, is equipped with a brake switch (36), which detects the operational condition of the brake, and a output rotation sensor (40), which detects the rotational speed of the output member of the transmission. If the control system detects the rotation of the output member by the output rotation sensor (40), then the control system terminates the neutral condition in spite of the operational condition of the brake, which is detected by the brake switch (36).
