Automatic parking system and method for electric vehicle

Abstract

The invention relates to the technical field of automatic parking, in particular to an automatic parking system and method for an electric vehicle, and the system comprises a mobile user module, a vehicle central control module, a GIS map module, an execution module, a parking result recording module, an abnormal data sorting, recording and analyzing module and an emergency processing module. The mobile user module comprises a garage parking mode and an outdoor parking mode. By setting the garage parking mode and the outdoor parking mode, selection can be made according to actual conditions in the automatic parking process, safety and effectiveness in the automatic parking process can be fully guaranteed, full safety of garage parking is guaranteed by adopting a parking track recording method through the garage parking mode, and the full safety of garage parking is guaranteed by adopting a parking track recording method in the outdoor parking process. If the parking space is parked, the information around the parking space is fully captured through the GIS map module, then a parking route is planned, then the safety during outdoor parking is guaranteed, garage parking and outdoor parking are treated in a distinguished mode, and then the requirements of vehicle owners are fully met.

Description

technical field [0001] The invention relates to the technical field of automatic parking, and in particular, to an automatic parking system for electric vehicles and a method thereof. Background technique [0002] Automatic parking refers to the automatic parking of the car without manual control, which can help the driver to park automatically, especially in the process of urban parallel parking, which provides great convenience to the driver. At present, the automatic parking system The technology has gradually matured, and it has been able to make a fairly complete automatic parking process. However, as far as the current automatic parking technology is concerned, in the process of parking, there is often no distinction based on the actual situation, while outdoor parking and The difficulty of parking in the garage is different, which makes it impossible to meet the needs of the driver.

Problems solved by technology

[0002] Automatic parking means that the car automatically parks in place without manual control and can help the driver to park automatically. Especially in the process of parallel parking in the city, it provides great convenience to the driver. At present, the automatic parking system The technology has gradually matured, and it has been able to make a fairly complete automatic parking process. However, as far as the current automatic parking technology is concerned, in the process of parking, it is often not distinguished according to the actual situation, while outdoor parking and The difficulty of parking in the garage is different, which makes it impossible to meet the driver's needs well. At the same time, the existing automatic parking system can only make a single alarm prompt, and the overall system security still needs to be improved.

[0003] Chinese Patent No. CN105882651A discloses an automatic parking system. The automatic parking system only needs to install a vehicle control unit on each vehicle to realize automatic parking, thus reducing the parking cost for vehicle users. In addition, Since the data acquisition unit and central processing unit set in the parking lot can perform centralized management on several or even dozens of parking spaces, there is no need to set up multiple data acquisition units and central processing units, so it is beneficial to vehicle users and parking lot operators On the whole, it also reduces the parking cost. This invention only reduces the cost of parking and facilitates the management of the garage. It does not treat outdoor parking and garage parking differently, so there are still deficiencies.

[0004] Chinese Patent No. CN112109702A discloses an automatic parking system. This invention can adapt to automatic parking in various environments. It has a humanized design and a better safety factor. The system can detect obstacles that are close to the vehicle through the obstacle ranging early warning module. And send out the distance alarm prompt sound, collect the video image information behind the vehicle through the video image acquisition module, and then use the image processing and fusion module to fuse the collected image information with the real-time data generated by the steering wheel angle sensor in the data communication processing module, and calculate by the reversing trajectory The module calculates and generates the reversing trajectory prediction graph in real time, and finally uses the image recognition and playback module to display the generated static parking warning line, warning area and reversing prediction trajectory graph in different colors on the high-definition wide-angle LCD screen, which can be used in all directions Carry out automatic parking on the vehicle, improve the intelligent operation of the vehicle, and ensure the safety of the driver, passengers and on-board cargo, and greatly reduce the incidence of traffic accidents caused by parking. Although the parking safety has been improved, However, there is still no targeted treatment for garage parking and outdoor parking, and there are still deficiencies in actual parking.
