Patent ID: 8651589

Claim:
A control device which performs a control of actuating a parking brake during operator's absence in an industrial vehicle including a seat switch which detects an operator's seating state, a vehicle speed sensor which detects vehicle speed, and the parking brake controlled by a brake solenoid, wherein the control device includes a counter which counts an elapsed time after the seat switch detects the operator's absence, and sets a preset absence time, wherein the control device is constructed such that, when the seat switch has detected absence, it is determined that the operator has completely left the seat and from the vehicle, and a control signal which validates the parking brake is output to the brake solenoid, thereby actuating the parking brake, if the vehicle speed detected by the vehicle speed sensor is equal to or less than a predetermined vehicle speed indicating a vehicle stopped state, and if the elapsed time counted by the counter becomes equal to or more than the set preset absence time, the counter is reset if the vehicle speed detected by the vehicle speed sensor becomes equal to or greater than the predetermined vehicle speed after the counting by the counter has started, wherein the industrial vehicle includes a shift range detecting means which detects a shift range instructed by shift operating means, and a parking brake operating portion which controls the parking brake by operation of an operator, and wherein when all of three signals; a seating detection signal that detects seating detected by the seat switch; a switching signal that detects the parking brake being switched to a valid side in the parking brake operating portion by the operator; and an input signal indicating forward or reverse detected by the shift range detecting means, are detected, the parking brake operating portion releases the parking brake.
