Abstract:
1. An engine stall prevention system for industrial vehicles, each of the industrial vehicles comprising a transmission, which is configured such that a hydraulic shuttle valve for performing forward and reverse switching without requiring operation of a clutch pedal is attached thereto, and a control unit for controlling the shuttle valve, wherein the control unit receives a brake pedal operation signal from a brake detection unit for detecting operation of a brake pedal, detects a traveling state of a vehicle using a traveling detection unit, determines whether a speed of the vehicle and engine RPM of the vehicle are equal to or less than respective preset values, and performs automatic control such that the shuttle valve enters a neutral state or a half-clutch state, wherein a pressure sensor for detecting a pressure in a hydraulic line is mounted in order to detect whether the shuttle valve is entering the neutral state or the half-clutch state, and wherein the control unit performs control such that the half-clutch state is maintained during operation of the brake pedal.
