Problems solved by technology

[0003] In the actual driving process, using a proportional-integral-derivative controller (Proportion Integration Differentiation, PID) controller cannot guarantee the complete smooth operation of the vehicle in different environments, and the nature of the controlled object of the PID controller changes when the scene changes , there is no guarantee that it still has good tracking performance, which will lead to inaccurate control of the vehicle and affect driving safety

Embodiment Construction

[0065] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0066] In order to facilitate the understanding of the technical solution provided by the present application, the background technology of the present application will be described below first.

[0067]The inventors have found that when using the PID controller to control the operation of the vehicle, if the same PID controller is used to control the vehicle in different driving scenarios, the control quantity output by the PID controller, the accelerator parameter or the braking parameter cannot be applied to current scene. For example, when driving on flat ground, the braking parameters output by the PID controller can achieve smooth braking of the vehicle. In a downhill scene, due ...

Abstract

The embodiment of the present application discloses a vehicle control method, device and system. Specifically, the embodiment of the present application first obtains the environmental information of the road where the vehicle is located, and determines the driving scene of the vehicle according to the environmental information. Then, a PID controller corresponding to the driving scene is determined according to the vehicle driving scene. After the PID controller is determined, the vehicle operation parameter value is input into the PID controller to obtain the control amount, and the vehicle is controlled by the control amount. That is, in different vehicle driving scenarios, different PID controllers are used to control the vehicle, so as to realize precise control of vehicle operation, ensure vehicle driving safety and maintain vehicle performance.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to a vehicle control method and device. Background technique [0002] With the continuous development of automobile technology, autonomous driving technology has received a lot of attention. Self-driving cars rely on artificial intelligence, visual computing, radar, and positioning systems to allow computers to automatically and safely operate motor vehicles without any active human intervention. [0003] In the actual driving process, using a proportional-integral-derivative controller (Proportion Integration Differentiation, PID) controller cannot guarantee the complete smooth operation of the vehicle in different environments, and the nature of the controlled object of the PID controller changes when the scene changes , there is no guarantee that it still has good tracking performance, which will lead to inaccurate control of the vehicle and affect driving sa...
