文摘：	This paper describes a control concept for an electrohydraulic brake system for electric vehicles. The concept offers the possibility of generating any brake pedal feedback to the driver, so that the driver's perception of the brake pedal can be influenced and adapted to actual driving conditions. With this brake system, disturbances from the hydraulic part acting on the brake pedal are rejected by the control and do not affect the brake pedal feel. Such disturbances occur, for example, when the anti-lock system is active or, in electric and hybrid vehicles, when changing between recuperative braking and friction-based braking. Two examples are presented to show how different brake pedal feedback characteristics can be implemented. The developed control concept is analysed in simulations with a detailed non-linear model of the brake system in an electric vehicle environment. The simulation results show a very good performance for recuperative braking together with friction-based braking and for anti-lock system braking without affecting the pedal feedback negatively.
