When drivers hit the pasture stop foot pedal today, their foot moves a diver rod which is linked to the pasture brake booster and the master brake cylinder. 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.
By contrast, in the Mercedes-Benz Sensotronic Brake Control, a large number of mechanical components ar simply replaced by electronics. The brake booster will not be needed in future either. Instead sensors infer the pressure inside the master brake cylinder as well as the speed with which the brake pedal is operated, and track down these data to the SBC computer in the form of electric impulses. To post 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. In other haggle: during braking, the actuation unit is completely disconnected from the rest of the schema and serves the sole purpose of recording any given brake command.
Only in the event of a major duty period or power failure does SBC automatically use the work of the tandem master cylinder and instantly establishes a plow hydraulic link between the brake pedal and the bearing wheel brakes in graze to decelerate the railroad car safely.
The central control unit under the bonnet is the centerpiece of the electrohydraulic brake. This is where the interdisciplinary interaction of mechanics and electronics provides its greatest benefits - the microcomputer, software, sensors, valves and electric middle work together and allow totally novel, highly high-octane brake management:
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. For example, the...If you want to get a full essay, order it on our website: Orderessay
