These featured include: 1. Traffic Jam Assist, which breaks the vehicle automatically in the bumper-to-bumper traffic once the driver takes his or her foot off the accelerator. 2. The Soft-Stop function, which allows soft and smooth stopping in town traffic. Thus, SBC transforms the conventional hydraulic brake into a more powerful mechatronic system. In the old brake system, when drivers hit the brake pedal, their foot moves a piston rod which is linked to the 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 turn 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 are simply replaced by electronics. The brake booster will not be needed in future either. 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 Sensotronic Brake Control computer in the form of electric impulses. To provide the driver with the familiar brake feel, the engineers have developed a special simulator which is linked to the following master cylinder and which moves the pedal using spring force and hydraulics. In other words: during braking, the actuation unit is completely disconnected
