Abstract

Disclosed is an industrial vehicle (1) provided with: a brake (5) which provides driving force or braking force to a vehicle body (22); a lift pressure sensor (632) which detects pitching oscillation of the vehicle body; and a pitching control unit (62) which calculates a pitching control torque for reducing the pitching oscillation and also generates a pitching control signal for outputting the pitching control torque to the brake (5). When the industrial vehicle is in a loaded driving state, the pitching control unit (62) calculates the pitching control torque in accordance with an output value produced by the lift pressure sensor (632), and outputs the pitching control signal. The brake (5) is then driven in accordance with the pitching control signal.

Description

technical field [0001] The present invention relates to an industrial vehicle, and more specifically, to an industrial vehicle capable of suppressing the pitching vibration of the vehicle. Background technique [0002] In industrial vehicles, there is a problem that pitching vibrations are generated in the vehicle body when the vehicle is running under a load (during driving with loads loaded). This pitching vibration is a phenomenon in which the vehicle body vibrates in the front-rear direction with the axle as the axis of rotation, and it is not preferable because it causes swinging of loaded cargo and deterioration of the ride quality of the driver. The technique described in Patent Document 1 is known as a conventional industrial vehicle related to this problem.
