The invention discloses a hill start assisting device and a vehicle. The vehicle comprises the hill start assisting device. The hill start assisting device comprises a hill start switch, a two-position three-way valve and an ECU. In the hill start state, when the ECU receives a clutch loosening signal, the degree of opening of the two-position three-way valve becomes smaller gradually, so that braking force is reduced, an engine is accelerated, and the two-position three-way valve is closed till a wheel speed sensor detects that wheels start to rotate. When the hill start assisting device is used for assisting hill start, after a driver presses the hill start switch to set the vehicle to be in the hill start state, a clutch is loosened, then braking of the vehicle can be relieved gradually under the control of the ECU, the vehicle starts gradually, and operation during hill start is simplified for the driver.
