Abstract

A braking system for a motor vehicle, including friction brakes on the wheels of at least one axle, the brakes controlled by a friction brake control device; at least one electric machine connected to at least one wheel and controlled by an electric drive control device; a brake pedal for detecting a deceleration request; a wheel-slip controlling device; and a torque distributing device. The devices for detecting a deceleration request are connected to the wheel-slip controlling device, the wheel-slip controlling device specifying target braking torques for each wheel according to the parameters of the deceleration request. The wheel-slip controlling device connected to a torque distributing device which is connected to the friction brake control device and the electric drive control device and which specifies friction brake requests to the friction brake control device and generator brake requests to the electric drive control device according to the target braking torques.
