WIPO Patent Application WO/2020/013555
Kind Code:
A1
Abstract:
An automatic deceleration system for an industrial vehicle and construction equipment, according to the present invention, is configured such that when an OFF signal is input from an accelerator pedal switch during forward driving or reverse driving, a transmission control unit detects a current vehicle speed from a speed sensor, and, when the current vehicle speed is a braking start speed, while gradually closing an open solenoid valve of a forward side solenoid valve and a reverse side solenoid valve, controls a clutch unit interlocking with the solenoid valve to be controlled such that the clutch unit is connected to an axle part of the vehicle, such that the vehicle speed is decelerated to a prescribed creeping speed; and when an ON signal is input from the accelerator pedal switch during driving at the creeping speed, the transmission control unit opens either the forward side solenoid valve or the reverse side solenoid valve according to a forward or reverse stage signal input from a shift control unit and closes the other to thus control the vehicle such that the vehicle drives in the driving direction according to the forward or reverse stage signal.
