Sensotronic Brake Control (SBC) is an electrohydraulic brake system developed by Daimler and Bosch. The SBC system was introduced in class R230 SL, which went on sale in Europe in October 2001.
Sensotronic Brake Control (SBC) is the name given to an innovative electronically controlled braking system that Mercedes-Benz will adjust to future passenger car models. Continuing with the innovations of Mercedes ABS, ASR, ESP? And Brake Assist, this system is considered as another important milestone to improve driving safety. With Sensotronic Brake Control, electrical impulses are used to pass the driver braking commands to a microcomputer which simultaneously processes various sensor signals and, depending on the particular driving situation, calculates the optimum braking pressure for each wheel. As a result, SBC offers even greater active safety than conventional brake systems when braking in a corner or on a slippery surface. A high pressure reservoir and electronically controlled valves ensure that maximum braking pressure is available much earlier. In addition, the system offers additional innovative features to reduce the driver's workload.
Working
In a hydraulic braking system, the driver applies the force by means of a mechanical link from the pedal to the master brake cylinder. In turn, the master brake cylinder develops hydraulic pressure on the wheels. In contrast, the electrohydraulic brake SBC supplies the brakes with a supply of brake fluid from the high pressure hydraulic tank, which is sufficient for several braking events. A piston pump driven by an electric motor supplies a controlled brake fluid pressure between 140 and 160 bar in the gas diaphragm reservoir.
When the driver depresses the brake pedal - or when ESP intervenes to stabilize the vehicle - the SBC control unit calculates the desired target brake pressures on each individual wheel. By using independent pressure modulators, the system regulates the hydraulic pressure on each wheel. These four pressure modulators consist of an inlet valve and an outlet valve, controlled by electronic output stages.
The system uses a travel sensor and a pressure sensor on the pedal to measure the speed and strength of the driver's command. The control unit processes this information and generates the control signals for the wheel pressure modulators. Normally, the master brake cylinder is disengaged from the brake circuit. A pedal travel simulator generates a normal pedal feedback. If the ESP intervenes, the high pressure reservoir supplies the required braking pressure quickly and accurately to the selected wheels without any intervention by the driver.
