bremseputer

Bremseputer is a term used in automotive engineering to describe a brake control computer embedded in a vehicle’s braking system. It coordinates sensor data and actuator commands to regulate braking force and is a central element of anti-lock braking (ABS), electronic brake-force distribution (EBD), and stability control systems.

Function and inputs: The Bremseputer is a real‑time, safety‑critical processor. It reads wheel-speed sensors, brake pedal input, hydraulic pressure sensors, and, in some designs, steering angle or yaw measurements. Using software algorithms, it computes the appropriate brake torque for each wheel and issues control signals to electronic hydraulic valves or actuators. Communication with other vehicle controllers typically occurs over CAN, LIN, FlexRay, or automotive Ethernet.

Architecture and variants: Systems may be centralized, with a single Bremseputer managing all channels, or distributed across wheel modules. Modern implementations often integrate ABS, traction control, and electronic stability control into one or more units, and may operate in brake-by-wire configurations that use electric actuation rather than purely hydraulic control.

Safety and standards: Because braking is safety-critical, development follows functional safety practices such as ISO 26262, with redundancy, fault detection, and diagnostics. Hardware and software are designed with fault tolerance and monitoring to meet ASIL requirements in different markets and applications.

Applications and context: Bremseputers are used in passenger cars, commercial vehicles, and motorcycles. They are central to regenerative braking integration in hybrid and electric vehicles and are a focus of ongoing advances in brake-by-wire, energy recovery, and vehicle automation. In English-language literature the function is usually called a brake control module or brake control unit.
