Abstract

The invention provides an automatic parking control method for a vehicle, the method comprises the steps that 1, the vehicle enters an automatic parking mode; 2, real-time position information of the vehicle is obtained through a position sensor; 3, a PID control module calculates a required parking rotation speed of the steering motor according to the real-time position information of the vehicle; 4, an electric control unit conducts real-time detection on the running state of the vehicle, and obtains the real-time rotation speed of the steering motor; 5, a comparing module compares the parking rotation speed of the steering motor and a real-time rotation speed, and obtains a difference value between the parking rotation speed of the steering motor and the real-time rotation speed; 6, the electric control unit adjusts the real-time rotation speed of the steering wheel motor according to the difference value, so that the real-time angle of the steering wheel rotation is corrected to the parking angle by which the steering wheel should turn; 7, step 2 to step 6 are repeatedly executed until parking of the vehicle is completed. The automatic parking control method for the vehicle can guarantee that the vehicle can be rapidly parked in place.

Description

technical field [0001] The invention relates to an automatic parking control method, in particular to an automatic control method and system for a steering wheel of a vehicle during parking. Background technique [0002] Along with the total amount of automobiles increasing, it is difficult to park vehicles in big cities as a common phenomenon. During the parking process, the driving skills of the driver are very high. A slight lack of skill of the driver during the parking process may lead to a safety accident of the vehicle and cause a lot of unnecessary troubles. Especially for novice drivers this is a high demand. Therefore automatic parking control method and system arise at the historic moment, make things convenient for the driver to park. [0003] The Chinese invention patent specification discloses a parking device and its parking method (patent number: ZL201210137830.X). The parking method comprises the following steps: [0004] S100. The detection unit detects ...
