Vehicle cruise control method and system, medium, electronic equipment and vehicle machine

The invention provides a vehicle cruise control method and system, a medium, electronic equipment and a vehicle machine. The vehicle cruise control method comprises the steps that speed deviation is obtained through calculation according to the preset speed of a vehicle and the speed of the vehicle; selecting variable control parameters according to the speed deviation subarea where the speed deviation is located, and performing subsection control on the requested acceleration; wherein the speed deviation subareas are subareas divided according to the speed deviation, and comprise a negative large area, a negative small area, a positive small area and a positive large area; and according to the variable control parameter and the speed deviation, calculating to obtain the PID control quantity of the vehicle constant-speed cruise. The control precision of the cruise control can be improved, and the speed fluctuation generated in the control process is reduced. 本申请提供一种车辆巡航控制方法、系统、介质、电子设备及车机。所述车辆巡航控制方法包括：根据车辆的预设速
