Abstract

The embodiment of the invention provides an automatic parking method and device. The method comprises the steps of when an obstacle is detected in the automatic parking process, obtaining the current vehicle speed and the current steering wheel angle; when the current vehicle speed is greater than a preset vehicle speed and the current steering wheel angle is greater than a preset turning angle, determining a target distance according to the change of the relative distance with the obstacle; and according to the target distance, adjusting a target vehicle speed used for controlling automatic parking. According to the method of the invention, the vehicle speed of automatic parking is adjusted according to the obstacle, the vehicle speed is prevented from being too high under the condition that the steering wheel angle is large, the obstacle can be effectively avoided at the large parking steering angle, and the safety of automatic parking is improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an automatic parking method and device. Background technique [0002] Reversing into storage is a method of parking vehicles, but it is difficult for some drivers to complete the operation of reversing into storage. With the increasing development of automobile technology, electric vehicles can realize automatic parking so that vehicles can automatically reverse into storage. [0003] In the process of automatic parking, if the vehicle reverses faster, when an obstacle appears, it is easy to avoid the obstacle in time and hit the obstacle. Especially when the steering wheel angle is relatively large, it is difficult to control the vehicle to turn at a large angle. However, in the prior art, obstacle avoidance based on ultrasonic radar detection values ​​is unstable, and false deceleration may occur. Contents of the invention [0004] In view of the above problems, a method an...
