Vehicle body positioning method and device and parking platform

Abstract

The embodiment of the invention discloses a vehicle body positioning method and device and a parking platform, and the method comprises the steps that push blocks below a left front wheel, a left rear wheel, a right front wheel and a right rear wheel of a to-be-controlled vehicle are controlled to move in the centering direction at the same time based on a centering instruction, the right front wheel push block and the right rear wheel push block perform centering movement at a first speed, and the right front wheel push block and the right rear wheel push block perform centering movement at a second speed; the left front wheel push block and the left rear wheel push block are centered at a second speed, and the first speed is higher than the second speed. The left wheel and the right wheel move towards the centering direction at different speeds, so that the left wheel and the right wheel can be separately controlled and do not influence each other, and the technical problem that in the prior art, the flexibility and compatibility are low when a vehicle body is positioned by adopting a method for synchronously clamping and centering the left wheel and the right wheel of a vehicle is solved; the technical effects that the control strategy of vehicle body returning is simplified, and the flexibility and compatibility of vehicle body returning are improved are achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of control, and in particular, to a vehicle body positioning method and device, and a parking platform. Background technique [0002] As the technology and services of new energy vehicles cannot be upgraded and perfected, the acceptance of the public continues to increase, new energy vehicles are becoming more and more popular, and more and more new energy charging and swap stations supporting them have entered people's field of vision. Chassis power exchange is the most common power exchange mode of new energy charging and swapping stations. The accurate positioning of the body is the basis for realizing the power exchange of the chassis. In the past, the positioning of the body used the method of synchronous clamping and centering of the left and right wheels, which requires additional wiring. Or the corresponding synchronization program can be achieved, and the origin calibration req...
