This paper describes a concept for an electrohydraulic brake system for electric vehicles. The concept offers the possibility to generate about any brake pedal feedback for the driver, so that the perception of the brake pedal can be influenced and adapted to actual driving conditions. The brake system is particularly suitable for vehicles with recuperative braking, as combined recuperative and friction-based braking can be accomplished with minimal influence on the brake pedal feedback. Two examples are presented to show how different brake pedal feedback characteristics can be implemented. The developed control concept is analyzed in a simulation with a detailed nonlinear model of the brake system in an electric vehicle environment. The simulation results show a very good performance for recuperative together with friction-based braking without negatively affecting the pedal feedback.
