摘要： An industrial vehicle 1 includes a brake 5 that applies a driving force or a braking force to a vehicle body 22, a lift pressure sensor 632 that detects pitching vibration of a vehicle body, and a pitching control unit 62 that calculates a pitching control torque for suppressing pitching vibration and generates a pitching control signal for causing the brake 5 to output the pitching control torque. When the industrial vehicle 1 runs under a load, the pitching control unit 62 calculates the pitching control torque based on an output value from the lift pressure sensor 632 to output the pitching control signal. The brake 5 is then driven based on the pitching control signal.
