Abstract

A braking-force control system and method is provided for a road vehicle having an electrically controllable four-circuit brake system. The braking forces generated by the individual wheel brakes can be adjusted in a wheel-specific way. Adjustment devices on a chassis vary the normal forces acting on the vehicle wheels, with at least one normal-force adjustment device being provided per vehicle wheel. The adjustment devices are configured so that, for the most part, the weight of the vehicle can be supported on one of the front wheels and on the rear wheel of the vehicle which is arranged diagonally opposite the latter. The braking force generated by a front-wheel brake and the rear-wheel brake which lies opposite the latter viewed along the diagonal of the vehicle, corresponds overall to the vehicle weight multiplied by a maximum coefficient of friction which is effective between the carriageway and the braked wheels.
