The invention provides an automatic parking device, belongs to the technical field of automotive braking and parking technique, and solves the problem of easy flameout caused by complex operation when an automobile starts uphill. The automatic parking device is connected with a braking system, and comprises a wheel speed sensor, an accelerator pedal sensor and an automotive electronic control unit (ECU); the braking system comprises a brake master pump; an electronic control part which can lock a piston is arranged in a cylinder body of the brake master pump; the electronic control part is connected with the automotive ECU; the wheel speed sensor transmits a brake signal to the automotive ECU when the wheel speed sensor detects that a rotating speed of the wheel is zero; the electronic control part locks the piston in the brake master pump; the accelerator pedal sensor transmits the running signal to the automotive ECU when the accelerator pedal sensor detects that an accelerator pedal acts; and then the electronic control part unlocks the piston in the brake master pump. The automatic parking device can omit the manual operation of parking, simplifies the uphill starting operation and a detecting element, and reduces vehicle electrostatic loss.
Description
technical field [0001] The invention belongs to the technical field of automobile braking and parking, and relates to an automatic parking device. Background technique [0002] The automobile braking system generally includes a drum or disc brake arranged on the wheel, a brake master cylinder and a brake pedal. The brake master cylinder and the brake pedal are connected through a vacuum booster. The master cylinder is connected through an oil circuit. After the master cylinder pumps oil to the brake cylinder, the brakes will be applied to slow down or stop the car. When parking, the car gear position needs to be placed on the neutral gear and then the parking brake is carried out by the hand brake. The parking brake is realized by pressing the brake shoe on the brake drum through a cable-type mechanical control mechanism. [0003] When starting to walk on an uphill slope, the parking brake, clutch pedal and accelerator pedal need to be operated together, so the operation is...
