Abstract

A brake-by-wire system for a motor vehicle provides haptic feedback to the driver via the brake pedal in the event of an anti-lock braking. The brake system includes a brake pedal configured to receive a braking request from a driver driving the motor vehicle and to forward the request to a braking apparatus. The braking apparatus is configured to translate the braking request into a corresponding brake pressure and to transmit it to brake actuators. The brake pedal is further mechanically and/or hydraulically decoupled from the braking apparatus. The brake system has at least one mechanical actuator in the form of a unbalance motor and/or a magnetic plunger. The at least one mechanical actuator is connected to the brake pedal and is configured to induce the brake pedal to vibrate in the event of an anti-lock braking.
