Problems solved by technology

[0003] For vehicles equipped with automatic parking system and air suspension at the same time, the sensor parameters in the automatic parking system have been calibrated at the factory, and the parameters are fixed. In actual applications, the vehicle height will vary with the adjustment of the air suspension. Changes caused the detection area of ​​the sensor to shift and vibrate relative to the factory state during parking, and the recognition and perception performance of markers, obstacles, parking spaces, etc. were also affected. For example, changes in vehicle height caused the camera to generate Distortion and distortion affect the recognition of parking spaces, etc., and ultimately affect the parking accuracy

Embodiment 1

[0037] figure 1 It is a schematic structural diagram of a parking control system provided by Embodiment 1 of the present invention. This embodiment is applicable to automatic parking of a vehicle equipped with an air suspension. The air suspension can be used to control the horizontal attitude of the vehicle body and adjust the stability system of the vehicle body. For vehicles equipped with air suspension, according to the different road conditions and the signal of the distance sensor, the trip computer will judge the change of the height of the vehicle body, and then control the air compressor and the exhaust valve to automatically compress or extend the spring to lower or lift the vehicle. High vehicle chassis ground clearance, thereby increasing the stability of the high-speed body or the passability of complex road conditions.

[0038] Such as figure 1 As shown, the parking control system includes: a parking controller 10, a parking sensor module 20, a panoramic imagin...

Embodiment 2

[0046] image 3 It is a schematic structural diagram of a parking control system provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments, and the panorama is determined according to the current height or preset height of the air suspension during parking. The process of valid calibration parameters of the camera is described in detail. It should be noted that for technical details not exhaustively described in this embodiment, reference may be made to any of the foregoing embodiments.

[0047] Specifically, such as image 3 As shown, the panoramic imaging module 31 is also used to calibrate corresponding calibration parameters of the panoramic camera 31 at multiple air suspension heights before parking.

[0048] Specifically, before parking, the calibration parameters (such as focal length, position parameters, etc.) of the panoramic camera 31, in addition to being statically calibrated before leaving the factory,...

Embodiment 3

[0063] Figure 5 It is a flowchart of a parking control method provided by Embodiment 3 of the present invention. This embodiment is applicable to the automatic parking of a vehicle equipped with an air suspension. Specifically, the parking control method can be executed by the parking controller 10, and the parking controller 10 can be realized by means of software and / or hardware, and integrated in the vehicle. For technical details that are not fully described in this embodiment, reference may be made to any of the above-mentioned embodiments. Such as Figure 5 As shown, the method specifically includes the following steps:

[0064] S110. Obtain the distance between the vehicle and the parking space marker during the parking process measured by the parking sensor module.

[0065] Specifically, the parking sensor module is provided with an ultrasonic sensor for sensing the distance between the vehicle and the parking space marker and providing a basis for automatic parki...

Abstract

The invention discloses a parking control system and method. The system comprises a parking controller, a parking sensor module, a panoramic imaging module, a vehicle body electronic stabilization system ESP and an electric power steering system EPS. The parking sensor module is used for measuring the distance between a vehicle and a parking space marker in the parking process. The panoramic imaging module comprises an imaging controller and a panoramic camera; the panoramic camera is used for collecting images of multiple view fields around a vehicle body, and the imaging controller is used for determining effective calibration parameters of the panoramic camera according to the current height or the preset height of an air suspension in the parking process and splicing the images of themultiple view fields according to the effective calibration parameters to obtain a panoramic image; and the parking controller controls the ESP and the EPS according to the distance and the panoramicimage, so that the vehicle is parked in the parking space. The calibration parameters of the panoramic camera are adjusted according to the height of the air suspension to obtain an accurate panoramicimage, so that the parking space is accurately recognized, and the accuracy of automatic parking is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, and in particular to a parking control system and method. Background technique [0002] With the development of intelligent connected vehicles (Intelligent Connected Vehicle, ICV), more and more vehicles are equipped with automatic parking systems, which can automatically identify parking spaces through sensors and controllers, and automatically drive vehicles to make them park in parking spaces. At the same time, some vehicles are equipped with air suspension. Under different road conditions, the automatic compression or extension of the spring of the air suspension can be controlled to automatically adjust the height of the vehicle body, thereby increasing the stability of the high-speed vehicle body or the passability of complex road conditions. [0003] For vehicles equipped with automatic parking system and air suspension at the same time, the sensor parameters ...
