The invention provides a vehicle anti-slip control method and device, and the method comprises the steps: monitoring the wheel speed of a driving wheel and the wheel speed of a non-driving wheel of a target vehicle under an active parking control process; according to the wheel speed of the driving wheel and the wheel speed of the non-driving wheel, the current driving wheel slip rate of the target vehicle is calculated; when the slip rate of the driving wheel is larger than a preset slip rate threshold value, the driving force is determined according to the wheel speed of the driving wheel and the wheel speed of the non-driving wheel, and the driving force is controlled in a closed-loop mode; monitoring a first current non-driving wheel speed of the target vehicle; and when the first current non-driving wheel speed is smaller than a first preset wheel speed threshold value, braking force is actively loaded. Therefore, the method and the device can actively prevent the vehicle from sliding on the slope, are good in applicability and can realize safe and stable parking of the vehicle.
