Problems solved by technology

[0004] At present, most of the automatic parking systems on the market are initially searching for the parking scene of the car in a lateral straight line, and do not involve the situation that the parking scene presents a concave or convex curve. Carrying out parking in the road scene, the final vehicle parking situation is poor, and the parking accuracy is low. In view of this, it is necessary to provide a parking scene recognition method for the initial library search stage of automatic parking to solve the above problems.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0023] figure 1 It is a flow chart of the parking scene recognition method in the initial library search stage of automatic parking. The method steps are as follows:

[0024] 1) Start the automatic parking system and enter the initial library search stage;

[0025] 2) The automatic parking controller collects the steering wheel angle data at regular intervals and stores them in the predefined array data1 in turn, where the first element of the array data1 is the initial angle; the system is set to collect the steering wheel angle every 50ms The value of the sensor can collect 200 steering wheel angle values ​​within 10s. In order to prevent data overflow, the system sets the size of the array data1 to 300;

[0026] 3) Perform difference processing on two adjacent elements in the array data1, and store each difference value in the array da...

Abstract

The invention relates to a parking scene recognition method for an initial space searching stage of automatic parking. Aiming at occurrence of a recessed or raised curve in a parking scene, the parking scene recognition method for the initial space searching stage of automatic parking is provided to enable a vehicle to be parked in a target packing space positioned at the recessed or raised curve accurately. By the parking scene recognition method, the parking scene in the initial space searching stage of automatic parking can be recognized effectively, the problems of poor parking effect and low accuracy of an existing automatic parking system in recessed curve parking scenes and raised curve parking scenes are solved, environmental adaptability of the automatic parking system is improved, and intellectuality of automatic parking is further improved.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parking scene recognition method for the initial library search stage of automatic parking. Background technique [0002] With the rapid increase of car ownership, the problem of "difficult parking" in modern cities has become increasingly prominent. It is not easy for many drivers to perform parking operations on crowded and narrow urban roads and parking areas on the side of residential roads. Therefore, parking assistance driving technology has become one of the research hotspots in the field of automotive engineering. [0003] The initial library search stage is the initial stage of the automatic parking system, which plays a vital role in the subsequent parking process. The role of the initial library search stage is to detect whether the size of the target parking space meets the size requirements of the car. The target parking space The accuracy of recognition...
