The invention discloses an industrial vehicle inching control system and control method. The industrial vehicle inching control system comprises an inching proportional valve, a brake assembly, a hydraulic clutch connected with the inching proportional valve, a vehicle speed sensor used for detecting the traveling speed of a vehicle, a displacement sensor used for detecting the position of an inching pedal and generating a position signal, and a pressure sensor used for detecting the oil pressure of the hydraulic clutch. And a micro-motion controller. The micro-motion controller is connected with a displacement sensor, the vehicle speed sensor, the pressure sensor, the micro-motion proportional valve and the brake assembly, and the micro-motion controller is used for controlling the micro-motion proportional valve to adjust the hydraulic clutch according to a position signal of the displacement sensor when the traveling speed is smaller than a preset speed; and when the oil pressure at the hydraulic clutch reaches the preset pressure, the brake assembly is controlled to brake. The industrial vehicle inching control system can accurately control the inching and braking linkage gap, and the inching control precision is improved.
