Abstract
A forward/reverse drive controller for controlling a vehicle, in which the output of an engine is transmitted through a clutch to an automatic transmission, in which the running direction of the vehicle is changed rapidly and alternately in opposite directions. The controller utilizes a clutch controlling actuator for the variable control of the working condition of the clutch between an engaged state and a disengaged state; a speed change actuator provided in the automatic transmission to shift the automatic transmission; a running speed sensor for detecting the running speed of the vehicle; a forward/reverse shift control lever which is shifted manually to three drive positions, a forward/reverse gear position detector; a braking control unit which applies a braking force when a forward/reverse gear position detector detects the shift of the forward/reverse shift control lever; a decision unit which decides, on the basis of the result of detection of the running speed of the vehicle, whether or not the running speed of the vehicle has been reduced to a predetermined running speed; and a shifting operation control unit which provides a command for shifting the automatic transmissi…
