Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary parking devices, and in particular to an auxiliary parking device for an intelligent car. Background Art

[0002] With the development of vehicle control technology, automatic parking technology has gradually been integrated into more car models. Automatic parking technology can identify parking spaces through radars and cameras installed on vehicles, plan parking trajectories through regulatory control algorithms, and complete automatic parking by handshaking with vehicle-related parts. As the number of cars in my country continues to increase, parking problems are becoming more and more serious.

[0003] The most commonly used parking methods in China are ground parking and underground garage parking, especially in places such as shopping mall underground parking garages and community underground garages where the lighting is not strong and there are densely parked vehicles. The white parking space boundary lines on the ground are not obvious. If there is water accumulation, the parking space boundary lines on the ground cannot be seen clearly, which seriously affects the efficiency of automatic parking. At this time, the owner can only rely on the radar and camera on the smart car to determine the vehicle position and park manually. The vehicle position often cannot enter the parking space vertically, affecting the parking of vehicles on both sides and further affecting the space utilization in the parking lot.

[0028] The working principle of this utility model:

[0029] When a vehicle approaches, the recognition module 6 at the front end of the support frame 2 collects the vehicle model and vehicle driving behavior, and the data is collected to the external control module. When the vehicle is recognized to be approaching, the external control module, based on the vehicle model, feedback drives the adjustment drive group 11 to adjust the width between the support frames 2 so that the distance between the two groups of projection components 41 is slightly larger than the vehicle width. When the vehicle adjusts its position to park, the ranging module 5 dynamically monitors the car's entry position. When one side of the vehicle is too close to the projected parking space boundary line, the prompt component 41 changes color and flashes, prompting the driver to appropriately adjust the steering wheel angle and adjust the vehicle's entry angle. After the vehicle is completely parked in the parking space, the recognition module 6 detects that the distance of the car does not exceed the parking space line, and the prompt component 42 and the projection component 41 go out, completing the parking process.
