Abstract
A method and apparatus for controlling the steering of a vehicle that is tracked or that has non-steerable wheels, by applying a steering command signal to a differential control system for controlling the wheels or the tracks of the vehicle, which steering command signal is obtained on the basis of a steering instruction given by an operator or a driver of the vehicle, as modified by a correction effect obtained from a signal representative of the instantaneous angular velocity in yaw of the vehicle as provided by a rate gyro sensor and as amplified by a gain k that varies as a function of the stable or unstable behavior of the vehicle in steering. The invention makes it possible to ensure that the vehicle remains stable while steering by avoiding uncontrolled skids or oversteer.
