Automatic parking system and method

Abstract

The embodiment of the invention discloses an automatic parking system and method. The system comprises an automatic parking control module, a surrounding environment information acquisition module and a braking module, the automatic parking control module is in communication connection with the surrounding environment information acquisition module and used for acquiring state information and traffic information of a vehicle in front of a main vehicle, and the automatic parking control module is in communication connection with the braking module and used for braking the main vehicle. And the automatic parking control module is used for acquiring braking information according to the state of the braking pedal provided by the braking module, and is also used for controlling the main vehicle to activate an automatic parking function when the state information of the vehicle in front of the main vehicle, the traffic information and the braking information meet automatic parking activation conditions. According to the technical scheme of the embodiment of the invention, additional operation when a user needs to automatically park during driving is reduced, and the driving experience of the user and the intelligent experience of a whole vehicle system are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automatic vehicle control, and in particular to an automatic parking system and method. Background technique [0002] The parking brake can lock the rotating shaft or the rear wheel when the car is parked, and give the car a resistance so that the car does not slip. In an automatic car, the parking brake is the parking gear. The automatic parking (Auto Vehicle Hold, AVH) function can automatically turn on the parking brake when the car is parked, and can help the driver to automatically maintain the vehicle braking force through the electronic control system and free the driver's right foot when needed. [0003] At present, without considering the road conditions, there are usually the following ways to activate the AVH function: 1) Activate by lightly depressing the brake pedal. Activating the AVH function in this way is relatively simple and requires no additional operations. Howe...

Problems solved by technology

Activating the AVH function in this way is relatively simple and requires no additional operations. However, since the brake pedal is located under the driver's foot, it is easy to be activated by mistake, affecting the user's starting speed and reducing the driving experience; 2), setting a separate activation switch with the AVH function , after the driver brakes the vehicle, the driver needs to manually turn on or off the switch, which increases the user's operational burden and reduces the intelligent experience of the vehicle system; 3), the driver depresses the brake pedal , and activate the AVH function through specific operations, for example, based on the depth of the brake pedal, the function is activated by increasing the pedal depression depth, which needs to be activated deliberately by the driver, even if the false activation is avoided, it still needs to be driven The additional operation of the operator also reduces the intelligent experience of the vehicle system

[0004] In addition, considering the road conditions, there are usually the following types of activation of the AVH function at present: 1) Based on the navigation information, the AVH function is turned off in congested road conditions. Self-judgment and activation of the ACH function; 2), based on sensors such as cameras, obtain the environmental information of the surrounding roads of the car, and actively follow and stop the car in front. In congested conditions, if the driver frequently activates the activation or deactivation of the AVH function, the driver's driving experience will also be reduced
