Abstract:
1. A clutch control device for an industrial vehicle, comprising: an engine; a brake device that applies a brake to the industrial vehicle according to operation of a brake pedal; a braking force detection device that detects braking force of the industrial vehicle applied by the brake device; a transmission that includes a forward clutch, a reverse clutch and a plurality of speed change clutches for switching speed stages, and is controlled to shift speed to a set speed stage by engaging one of the forward clutch and the reverse clutch that has been selected and one of the plurality of the speed change clutches that has been selected and to transmit output torque of the engine; a speed stage detection device that detects the set speed stage of the transmission; a clutch cut off selection device that selects whether or not to execute a clutch cut off control in which the forward clutch is released with increase in the braking force according to the operation of the brake pedal; a clutch control device that controls engage/release of the forward clutch if the clutch cut off selection device selects the clutch cut off control to be executed so that the forward clutch is released when one of a plurality of clutch cut off conditions is judged to be satisfied based upon braking force of the industrial vehicle detected by the braking force detection device, with the plurality of clutch cut off conditions being arranged so that with a greater braking force of the industrial vehicle, the forward clutch is released at a later timing; and a switching device that automatically switches among the plurality of clutch cut off conditions in the clutch control device based upon the set speed stage of the transmission detected by the speed stage detection device.
