The invention relates to the technical field of vehicle control, and discloses a vehicle control method and device, wherein the vehicle control method comprises the steps of obtaining vehicle state parameters of a vehicle in response to the vehicle running on a separated road, wherein the vehicle state parameters comprise braking control parameters, determining a separated road control state of the vehicle based on the vehicle state parameters, determining a target braking force difference value of the vehicle based on the braking control parameters, determining a first braking force difference value based on the separated road control state and the target braking force difference value, and dynamically adjusting the braking force of a first wheel of the vehicle based on the separated road control state, the first braking force difference value and the braking control parameters, wherein the first wheel is a high-attachment-side rear wheel of the vehicle when the vehicle runs on the separated road. The braking force of the high-side rear wheel is dynamically adjusted, the braking force of the high-side rear wheel is improved as much as possible while the stability of the vehicle is ensured, so that the deceleration performance is improved, the braking efficiency is improved, and the braking distance is shortened.
