Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] image 3 is a schematic diagram of the basic structure of the parking control device according to the embodiment of the present invention. Such as image 3 As shown, the parking control device 30 of the embodiment of the present invention includes an acquisition module 31 and a calculation module 32 . The acquiring module 31 is used to acquire the start position and the end position of the vehicle, and the calculation module 32 is mainly used to calculate the parking trajectory at a preset vehicle speed according to the constraints and the start position and end position of the vehicle.

[0033] In implementation, the acquiring module 31 can acquire the starting position and the ending position of the vehicle in various existing or future ways. The position of the midpoint of the rear axle of the vehicle can be used as the po...

Abstract

The invention discloses a parking control device, a parking control system and a parking control method for solving the problem of high error between a vehicle running locus and a designed locus during parking control in the prior art. The parking control device comprises an acquisition module and a calculation module, wherein the acquisition module is used for acquiring the starting position and the final position of a vehicle; the calculation module is used for calculating a parking locus at a preset speed according to constrained conditions, the starting position and the final position, wherein the constrained conditions comprise a highest allowed speed of the vehicle, a maximum turning speed of a front wheel of the vehicle and a maximum turning angle of the front wheel of the vehicle during parking; and the curvature of the parking locus is continuously changed, the parking locus comprises an arc and a curve connected with two ends of the arc, and the radius of the arc is the turning radius when the front wheel of the vehicle reaches the maximum turning angle. By using the technical scheme, the actual running locus of the vehicle accords with the designed locus during parking.

Description

technical field [0001] The invention relates to a parking control device and system and a parking control method. Background technique [0002] At present, more and more vehicles are equipped with parking control function, which can control the vehicle to enter the parking space. Figure 1A is a schematic diagram of a parking control trajectory according to the prior art. according to Figure 1A With the S-shaped trajectory 10 shown, the vehicle can realize lateral parking to the right. If parking on the left side, then drive along the mirrored curve with the left or right of the track 10, that is, the parking track at this time is an anti-S shape. Such as Figure 1A As shown, the positional relationship between the vehicle and the parking space PA is known, and the position U of the target parking position when the vehicle is parked and stopped can be determined, which is usually the midpoint of the rear axle. [0003] According to the existing method, the parking traject...
