Claims

[Scope of utility model registration request]

A friction clutch connected to an engine mounted on a vehicle and operated intermittently by a clutch actuator, a gear type transmission connected to the friction clutch and capable of switching the meshing state of each gear by a gear shift unit, and the vehicle An actuator that turns on and off the wheel brake, a vehicle speed sensor that outputs vehicle speed information, and a hill start assist switch installed on the vehicle.When an on command is received from the hill start assist switch, the wheel brake is turned on and hill start assist processing is performed. In the automatic transmission device for a vehicle, the control means is connected to a strong brake pedal force sensor that is turned on when strong brake pedal force information is received, and the control unit is configured to detect when the vehicle speed value is in a vehicle stop range and An automatic transmission device for a vehicle, characterized in that when the strong brake pedal force information is input, the actuator for operating the wheel brake is turned on.
