The system described proportions the brake force at each wheel according to the dynamic load on that wheel in a corner or manoeuvre. Brake pressure is modulated when the brakes are applied in a corner and also when a severe steering input is made whilst braking in a straight line.
The paper discusses the need for such a system and presents an analysis of system performance on a typical passenger car. Changes to the oversteer/understeer characteristics of the vehicle are also analysed.
The system is currently under development and has been fitted experimentally to three vehicles. Test results from one of these vehicles are presented.
