Abstract

The invention discloses a method and a device for controlling vehicle movement. The method comprises the steps that a vehicle movement track curve obtained through calculation by adopting an Emmette Hermite interpolation method is adopted, coordinates of the actual position of a current vehicle are obtained, and coordinates of a target position positioned on the vehicle movement track curve and corresponding to the actual position are determined according to the coordinates of the actual position and coordinates of a vehicle movement end point; and according to the coordinates of the actual position and the coordinates of the target position, the position offset between the actual position and the target position is calculated, the compensation amount of the angular velocity of current vehicle movement is determined according to the position offset, and the angular velocity of vehicle movement is adjusted based on the compensation amount of the angular velocity until it is detected that the vehicle moves to the end point position. The technical problem that in the prior art, applicability is poor is solved.

Description

technical field [0001] The present application relates to the technical field of smart cars, in particular to a method and device for controlling vehicle movement. Background technique [0002] In recent years, with the continuous development of autonomous driving technology, the two-dimensional code technology is applied to the automatic guided vehicle navigation technology (AGV Navigation Technology, AGV), that is, the two-dimensional code containing coordinate information is pasted to the corresponding position at a certain distance, Then, the vehicle captures the two-dimensional code image through the on-board camera during operation, returns the AGV position coordinates contained in the two-dimensional code and extracts the coordinates of the two-dimensional code feature points in the image coordinate system, and obtains the AGV position deviation and angle deviation through coordinate conversion , and then adjust the speed of the two wheels of the AGV to achieve deviat...
