Example Embodiment

[0030] Example one

[0031] Figure 1A The present application is to implement a parking trajectory embodiment provides a flowchart of a method of automatically determining, in the embodiment of the present embodiment is applicable to the process with the initial vertical posture narrow parking the vehicle in parking, the parking trajectory is determined automatically the case. This method provided a parking trajectory embodiments may be implemented by means of the present application performed automatically determined, the apparatus may be implemented by software and / or hardware manner, and integrated electronic device to run this system.

[0032] like Figure 1A Shown, the automatic parking trajectory determination method comprising:

[0033] S110, determining the first corresponding to the first parking parking trajectory of the vehicle steering angle according to the initial position and the target parking position.

[0034] When parking at the parking complex, narrow parking...

Example Embodiment

[0051] Example 2

[0052] Figure 2A It is a flow chart of another parking trajectory automatic determination method according to Example 2 of the present application. This embodiment is further optimized based on the above embodiment. Specifically, the operation "according to the end of the target parking position, the relative positional relationship between the initial position of the vehicle tail outer edge angle, and the initial position of the edge angle of the vehicle tail, determines the first parking track segment corresponding to the first parking track segment. A parking steering angle is further refined.

[0053] like Figure 2A As shown, the parking trajectory automatic determination method includes:

[0054] S210, according to the initial position of the vehicle, the vehicle initial position, the vehicle target position, and the minimum turn radius are determined to be the first center of the center as the first center.

[0055] Since the axial direction of the initia...

Example Embodiment

[0084] Example three

[0085] Figure 3A It is a flow chart of another parking trajectory automatic determination method according to Example 3 of the present application. This embodiment is further optimized based on the above embodiment. The specific optimization is, according to the relative positional relationship of the first termination point and the target parking position, it is determined that the second parking steering angle and the third parking steering angle, including: determining parallel to the rear axle of the vehicle and passing The straight line of the first termination point determines the center of the second parking trajectory to the second center of the first centering, the first centering point to the first center and the second center. The distance is equal to the minimum turning radius; if the horizontal distance of the second center and the target parking space is less than the minimum turn radius, the second parking steering angle and the center accord...

Abstract

The embodiment of the invention discloses a parking track automatic determination method and device, a medium and electronic equipment. The method comprises the steps: determining a first parking steering angle corresponding to a first parking track section according to the initial position of a vehicle and the position of a target parking space; determining the termination position of the first parking track section as a first termination point according to the initial position of the vehicle, the first parking steering angle and the minimum turning radius; determining a second parking steering angle and a third parking steering angle according to the relative position relation between the first termination point and the target parking position; and determining a second parking track section and a third parking track section according to the second parking steering angle and the third parking steering angle, and determining a parking track according to the first parking track section, the second parking track section and the third parking track section. According to the technical scheme, the parking track calculation efficiency can be improved, the parking distance can be shortened, and the parking safety can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computer applications, and in particular to a method, device, medium and electronic equipment for automatically determining a parking trajectory. Background technique [0002] The number of existing parking spaces is difficult to adapt to the rapidly growing number of cars, making the parking environment more and more complicated, and the parking space is getting narrower and narrower. The complex and narrow parking environment undoubtedly increases the difficulty of parking for drivers. [0003] Aiming at the problem of "difficult parking", there are currently many automatic parking trajectory determination methods, but these automatic parking trajectory determination methods often have parking trajectories when planning a vehicle's parking path in the face of narrow and vertical parking spaces. Computational efficiency is not high. Contents of the invention [0004] The e...
