A vehicle safety system

A method to reduce the likelihood of over-steer in a vehicle during a turn, the method, comprising the steps of: detecting that a vehicle is negotiating a turn in a manner that may result in an over-steer situation; determining inner and outer wheels of the vehicle, the inner wheels of the vehicle being those on the side towards which the vehicle is turning; determining the slip ratio of the forward outer wheel and the slip ratio of the rear outer wheel; and if the slip ratio of the rear outer wheel is below a first threshold, then: if the slip ratio of the front outer wheel is below a second threshold, applying additional braking to the front outer wheel only, without also applying additional braking at the rear outer wheel; or if the slip ratio of the forward outer wheel is above the second threshold, applying additional braking both to the front outer wheel and to the rear outer wheel.
