Abstract Within the standard architecture, hydraulic brake systems of passenger vehicles must decelerate the vehicle according to the driver’s request and to legal requirements (i.e., ECE R13H). Wheel forces generated during braking are transferred via tires to the road surface in such a way that the vehicle remains stable and controllable and always follows the driver’s intention. The basis for this is optimized pedal feel and optimized distribution of brake forces left/right and front/rear. Architectures can be extended to influence fuel consumption and emissions. The combination of internal combustion engines and electric machines (“hybrid drive”) as well as electric drive is becoming more widespread in passenger vehicles. Coupling of electric machines and drivetrain generates electric power by brake energy recuperation. The impact on brake system design is to offer the same pedal feel, independent of whether the vehicle is braked by an electric machine and/or by friction brakes (brake blending). Electronically controlled hydraulic brake systems (e.g., ABS, TCS, ESC) optimize vehicle dynamics. Together with beam and image sensors, this opens various opportunities to utilize additional brake system functions, i.e., for advanced driver assistance systems (ADAS), to fulfill future vehicle safety requirements. The performance of these advanced assistance systems mainly depends on vehicle system and component layout, hardware, software, sensors, and HMI.
