An industrial vehicle includes a transmission, which is coupled to an
engine by a torque converter. When the vehicle is accelerating, the
rotational acceleration of driving wheels is computed based on the
rotational speed of the driving wheels. A traction control procedure is
executed based on the rotational acceleration for eliminating spinning of
the driving wheels. When the vehicle is decelerating, the rotational
deceleration of the driving wheels is computed based on the rotational
speed of the driving wheels. An anti-lock brake control procedure is
executed based on the rotational deceleration for preventing the driving
wheels from locking. As a result, skidding of the driving wheels is
reliably prevented by a simple structure.
