Abstract

The invention discloses a vehicle control method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: determining a driving scene of a vehicle; determining a target value of a control parameter according to the driving scene; determining a target function according to the target value of the control parameter; determining a control instruction according to a prediction model and the objective function; and controlling the vehicle to run according to the control instruction. According to the embodiment, the vehicle can run more stably, and the vehicle is prevented from being out of control.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a vehicle control method and device. Background technique [0002] Self-driving vehicles can drive in different scenarios such as structured roads and unstructured roads. In order to ensure the smooth operation of the vehicle in different scenarios, it is necessary to control the vehicle according to different scenarios. [0003] In the existing method, different controllers correspond to different control methods, and when the driving scene of the vehicle changes, it is necessary to switch the corresponding controller to control the vehicle. [0004] However, switching between different controllers can easily cause the vehicle to vibrate or even lose control. Contents of the invention [0005] In view of this, the embodiments of the present invention provide a vehicle control method and device, which can make the vehicle run more smoothly and prevent the vehicle fro...
