The present invention provides a running control device for an industrial
vehicle which generates no speed change shock when the traveling
direction is switched to the opposite direction by the forward-reverse
selection member during the running of the vehicle. The running control
device comprises a forward-reverse selected direction detection sensor
which detects the selected traveling direction, a transmission which has
a forward clutch and a reverse clutch that switch the traveling direction
between the forward direction and reverse direction, and which transmits
the driving torque of the engine to the driving wheels via the clutches,
a brake which applies braking to the vehicle, a vehicle speed sensor
which detects the vehicle speed, and a controller which gradually
decelerates the vehicle by means of the brake when the selected traveling
direction that has been detected is switched, and controls the engaging
force of the forward or reverse clutch corresponding to the selected
traveling direction and the braking force of the brake before the
detected vehicle speed reaches zero, thus controlling the deceleration
torque and acceleration torque so that the fluctuation in the
acceleration around the point of time at which the traveling direction is
reversed is weakened.
