PURPOSE: An inching function mechanism using a proportional valve is provided to increase convenience of a driver by allowing operating force of a brake pedal to be equal to operating force of an inching pedal. CONSTITUTION: A plurality of solenoid valve(210) selects each gear number of forward movement, reverse movement and the forward movement. Each solenoid valve is connected to a random gear number for the forward movement or the reverse movement. A proportional control valve(230) is connected to the solenoid valve. The proportional control valve performs an inching function and a shock reduction function during gear shift. |
