Sensotronic Brake Control
Sensotronic Brake Control (SBC) is an electro-hydraulic brake system developed by Daimler and Bosch. In this system, the wheel brake cylinders of a vehicle are operated through a servomechanism, offering precise and responsive braking.
The SBC system was first introduced on the R230 SL-class, which was released in Europe in October 2001.
The Sensotronic Brake Control (SBC) system operates using a hydraulic high-pressure reservoir to supply brake fluid. A piston pump, driven by an electric motor, generates controlled brake fluid pressure ranging between 140 bars (2,000 psi) and 160 bars (2,300 psi) in the gas diaphragm reservoir.
When the brakes are engaged, the SBC control unit calculates the necessary brake pressure for each wheel individually. This is achieved using four independent pressure modulators, each consisting of an inlet and an outlet valve controlled electronically.
The system includes a travel sensor and a pressure sensor at the brake pedal to measure the speed and force of the pedal application. The control unit processes these inputs and sends appropriate control signals to the wheel pressure modulators. Typically, the master brake cylinder is disconnected from the brake circuit, with a pedal travel simulator providing normal pedal feedback. In situations where the Electronic Stability Program (ESP) is activated, the high-pressure reservoir quickly delivers the required brake pressure to specific wheels with precision.
The Sensotronic Brake Control (SBC) system allows for precise control of brake pressure at each wheel, enabling the use of stability control methods such as Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). On some vehicles, the system incorporates features designed to enhance driver convenience, including:
In the event of a computer malfunction, SBC defaults to a conventional hydraulic master cylinder, which may require increased driver effort and result in longer stopping distances. Additionally, if the pump fails, the high-pressure reservoir retains sufficient pressure to allow for electronic braking.
In 2001, the μ-Club, an international association of brake technology experts, recognized Robert Bosch and Daimler Chrysler for their development of the electrohydraulic brake system, SBC.
