Abstract:
This application relates to the automobile field, and specifically, to a vehicle control method and apparatus, and the like. In the vehicle control method, when a steering mode of braking a rear wheel on an inner steering side is performed, target braking force of the rear wheel on the inner steering side is determined based on hand force applied when a driver performs a steering operation on a steering wheel, and steering control is performed based on the target braking force. In this way, steering control that well reflects an intention of the driver can be implemented, to avoid a case in which the driver frequently performs a driving operation to correct a traveling track of a vehicle, and reduce a driving burden. The method provided in embodiments of this application may be applied to an intelligent vehicle.
