Problems solved by technology

But the two control objectives are not completely decoupled, and the change of speed will cause the increase of position error
When the vehicle is controlled according to the position error, the speed of the vehicle will deviate from the target speed, which will lead to the inability to accurately control the vehicle to achieve two control goals at the same time

Embodiment Construction

[0062] For the above objects, features and advantages of the present disclosure more apparent, the following embodiments of the present application will be further described in detail in conjunction with accompanying drawings and specific embodiments.

[0063] To facilitate understanding of the technical solution provided herein, the following will first background art of the present application will be described.

[0064] The inventors have found that, in the process of moving the vehicle, the vehicle is usually controlled to achieve two objectives, namely position and velocity. That is, to realize that the position and the vehicle speed setting is set. However, in practice, the position and speed of the two goals are not completely decoupled. The so-called decoupling means, no association or association between two objects to a small extent, can be processed separately. In this way, there will be changes in speed may cause position errors increased, while the control system when...

Abstract

The embodiment of the present application discloses a vehicle control method, device and system. Firstly, the vehicle position error value and the vehicle speed error value are obtained simultaneously, and the weighted output of the vehicle position error value is calculated respectively to obtain the first parameter value, and the vehicle speed error is calculated. Weighted output of values ​​to obtain the second parameter value. The sum of the first parameter value and the second parameter value is input into the PID controller to obtain the control quantity for controlling the operation of the vehicle. That is, the embodiment of the present application weights the speed and position and controls the PID controller in stages to solve the problem of making the vehicle achieve the position target and the speed target at the same time, and improve the accuracy of vehicle control to ensure that the vehicle can simultaneously achieve Position target and velocity target.

Description

Technical field [0001] The present application relates to the field of automatic control technology, and more particularly to a vehicle control method, apparatus and system. Background technique [0002] With the continuous development of automobile technology, automatic driving technology is very concerned. Automatic driving vehicles relies on equipment such as artificial intelligence, visual computing, radar, and positioning systems, allowing the computer to automatically safely operating motor vehicles without any human proactive operation. [0003] In practical applications, when controlling the vehicle is controlled, it is usually divided into two control targets, namely positions, and speeds. However, between the two control goals is not fully decoupled, and the speed change can increase the position error. When the vehicle is controlled based on the position error, the speed of the vehicle will be disengaged from the target speed, and therefore, it is possible to accuratel...
