Embodiment Construction

[0062] The general scene-oriented automatic parking control system of the present invention divides the entire automatic parking process into four layers: an input layer, a strategy layer, a planning layer and a control layer. Such as figure 1 Shown:

[0063] The input layer is used to receive and perceive the vehicle speed, position, and the orientation and size of the berth in the current state; the strategy layer gives the control operation instructions for automatic parking according to the relevant information of the current vehicle and berth; the planning layer combines the dynamics of specific vehicles The model gives the planned parking trajectory; the control layer performs real-time feedback control according to the deviation between the actual parking trajectory and the planned parking trajectory.

[0064]First, the control commands and parking trajectory data sets of different types of vehicles are generated through MATLAB simulation software and parallel learning...

Abstract

The invention provides an automatic parking control system. The whole automatic parking process is divided into an input layer, a policy layer, a planning layer and a control layer by the system. In an automatic parking control process, the input layer generates control instruction and parking track data sets of vehicles in different types by virtue of simulation; the policy layer learns the simulation data by utilizing a deep neural network algorithm so as to extract the common relationship between control instructions and parking tracks; the planning layer finds a proper parking policy by virtue of training of few steps to give a control instruction for the parking scene, thereby generating a planning track; and the control layer performs control feedback according to the deviation of anactual parking track and the planning track so as to enable the parking track to be most similar to the ideal track planned by the system.

Description

technical field [0001] The invention relates to the field of automatic parking, in particular to an automatic parking control system for general scenarios. Background technique [0002] Parallel parking is a harrowing experience for many drivers, and with limited parking space in big cities, maneuvering a car into tight spaces has become a required skill. Parking is rarely done without a lot of trouble, and parking can lead to traffic jams, nerve fatigue and bumped bumpers. With the development of automatic parking technology, the above problems have been greatly improved. In addition to helping drivers park automatically, automatic parking technology can also help solve some parking and traffic problems in densely populated urban areas. Sometimes the ability to park in tight spaces is limited by the skill of the driver. Self-parking technology can park cars in smaller spaces than most drivers can park themselves. This makes it easier for car owners to find parking space...
