This is where the interdisciplinary interaction of mechanics and electronics provides its greatest benefits — the microcomputer, software, sensors, valves and electric pump work together and allow totally novel, highly dynamic brake management: These include Traffic Jam Assist, which brakes the vehicle Sensotronic brake controllers in stop-and-go traffic once the driver takes his or her foot off the accelerator.
The control unit processes this information and generates the control signals for the wheel pressure modulators.
The brake booster will not be needed in future either. In case of computer failure, SBC reverts to a hydraulic master cylinder, but driver effort and stopping distance is reported to increase.
In turn the master brake cylinder develops hydraulic pressure in the wheels. Advantages and disadvantages[ edit ] With fine-grained control of pressure at each wheel, SBC offers a unique platform in which to implement skid protection and traction control compared to cf.

What makes the system en more sophisticated is the fact that SBC calculates the brake force separately for each wheel. If ESP intervenes, the high-pressure reservoir supplies the required brake pressure quickly and precisely to selected wheels, without any driver involvement.
These four pressure modulators consist of one inlet and one outlet valve, controlled by electronic output stages.
To provide the driver with the familiar brake feel, engineers have developed a special simulator which is linked to the tandem master cylinder and which moves the pedal using spring force and hydraulics. The transmission control unit finally uses the data highway to communicate the current driving range.
As soon as you press the brake pedal and the sensors identify the driving situation in hand, the computer makes an exact calculation of the brake force necessary and distributes it between the wheels as required.
Normally, the master brake cylinder is detached from the brake circuit. In contrast, the electro-hydraulic brake SBC provides the brakes with a brake fluid supply from the hydraulic high-pressure reservoir, which is sufficient for several braking events.
Instead sensors gauge the pressure inside the master brake cylinder as well as the speed with which the brake pedal is operated, and pass these data to the SBC computer in the form of electric impulses.
By contrast, in the Mercedes-Benz Sensotronic Brake Control, a large number of mechanical components are simply replaced by electronics. In addition to the data relating to the brake pedal actuation, the SBC computer also receives the sensor signals from the other electronic assistance systems.
The result of these highly complex calculations is rapid brake commands which ensure optimum deceleration and driving stability as appropriate to the particular driving scenario.
Depending on the pedal force, the master brake cylinder builds up the appropriate amount of pressure in the brake lines which — in a tried and tested interaction of mechanics and hydraulics — then presses the brake pads against the brake discs via the wheel cylinders. Through the use of independent pressure modulators the system regulates the hydraulic pressure at each wheel.
These include Traffic Jam Assist, which brakes the vehicle automatically in stop-and-go traffic once the driver takes his or her foot off the accelerator. The Soft-Stop function - another first - assists with smooth stopping in town traffic.
The Soft-Stop function — another first — allows particularly soft and smooth stopping in town traffic When drivers hit the brake pedal today, their foot moves a piston rod which is linked to the brake booster and the master brake cylinder.
A high-pressure reservoir and electronically controllable valves ensure that maximum brake pressure is available much sooner.
A piston pump driven by an electric motor supplies a controlled brake fluid pressure between and Bar in the gas diaphragm reservoir.

As soon as you press the brake pedal and the sensors identify the driving situation in hand, the computer makes an exact calculation of the brake force.
With Sensotronic Brake Control, electric impulses are used to pass the driver's braking commands onto a microcomputer which processes various sensor signals simultaneously and, depending on the particular driving situation, calculates the optimum brake pressure for.
