Embodiment Construction
[0069] 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.
[0070] In order to facilitate the understanding of the vehicle control method provided by the embodiment of the present application, the background technology of the present application will be first described below.
[0071] In the research of the traditional vehicle control method, the inventor found that the traditional vehicle control uses a single-stage PID controller to control the speed of the vehicle. Due to the hysteresis of the vehicle speed change, the response time of the PID controller will be longer. Moreover, the output control quantity changes greatly and is sensitive to error disturbances, which cannot meet the requirements for stable vehicle control.
