Automatic control method and system for assistant parking

Abstract

The invention discloses an automatic control method for assistant parking. The method comprises the steps that the position of a brake pedal and the vehicle speed are detected in real time; if the brake pedal is pressed down and the vehicle speed indicates that a vehicle is in a non-deceleration state, assistant parking operation is conducted, wherein the assistant parking operation is conducted for braking tires and parking the vehicle; if the brake pedal is not pressed down and the vehicle speed indicates that the vehicle is decelerated to zero, the gear position of a gear lever is checked; when the gear lever is shifted to the neutral gear or the parking gear, the state of a hand brake is checked; and if the hand brake is not started and the brake pedal is uplifted, the assistant parking operation is conducted. Through the automatic control method, automatic assistant parking can be conducted on the vehicle when a driver forgets or fails to start the hand brake; and when a brake system fails, the functions of assistant braking and parking are achieved, and accordingly certain potential safety hazards are effectively eliminated. The invention further discloses an automatic control system for assistant parking.

Description

technical field [0001] The invention relates to the field of vehicle parking control, in particular to an auxiliary parking automatic control method and system. Background technique [0002] The so-called parking generally refers to keeping the vehicle in place. The parking control system must reliably ensure that the car parks in place and does not slip by itself under any circumstances. Of course, in some special working conditions, the vehicle will also be controlled by the parking system to assist in braking until the vehicle is in motion while the vehicle is running. stop, e.g. when conditions such as brake system failure occur. [0003] At present, the most common parking system is the use of handbrake technology, that is, the parking control system is manually activated; usually handbrakes are divided into mechanically operated handbrakes (some mechanically operated handbrakes use foot switches, but are also called handbrakes) and electronic handbrakes. The parking ...

[0004] However, no matter what kind of parking system is mentioned above, it relies on the active behavior of the driver to perform the parking operation, which will have certain safety hazards, such as: parking failure due to human forgetting or untimely operation; When the braking system fails, it is difficult to quickly switch to the parking system to assist emergency braking
