The vehicle might stop faster if the brakes are applied just hard enough to get maximum static friction between the tyres and road. If the brakes are applied harder than the wheels will lock, the tyres will slide on the road and a lesser kinetic friction will result. Then applying brakes in the vehicle is much less effective.
To prevent any skid and thus provide maximum effective brake, several devices have been suggested. Often skid control of the rear wheels is provided. Some others provide control at all the four wheels. As long as the wheels are rotating the antiskid device permits normal application of the brakes. But if the brakes are applied so tough that the wheels tend to stop turning and hence a skid starts to develop the device comes into operation and partly release the brakes so that the wheels continue to rotate. Still intermittent brakes continue. But it is held to just below the point where a skid would start. The result is maximum braking effect.
Antilock brake system: The hydraulic unit is the central component of an ABS system. Each of the four wheels has a speed sensor, which quantifies the rotational speed of the wheel. This information is monitored by an Electronic Control Unit: which opens and closes the magnetic valves at the right time. If a wheel is supposed to lock under heavy braking, the system continues to lower the hydraulic pressure on that wheel alone, till the threat of locking is past. Once the wheel is turning freely, the hydraulic pressure is enhanced. This increase and release of pressure continues until the driver lowers the force on the brake pedal or until the tendency to lock is overcome. ABS is incorporated in some of the cars to prevent skidding and to rove braking.
Senstronic braking control (SBC) Senstronic Braking Control is basically a brake-by-wire system which removes the need for mechanical linkage between the brake pedal and brake master cylinders. SBS also work in addition with ABS to increase braking.
It was created by Mercedes in association with Robert Bosch GmbH. Among its most significant performance features are the dynamic building up of brake pressure and the precise monitoring of driver and vehicle behaviour using sensors. In an emergency situation, SBC increases brake line pressure and readies the brakes, so that they can grip immediately with entire force when the brakes are applied.
Moreover, variable brake facilities offers more safety when applying brake on bends. SBC controls each wheel individually. At the corners, they apply varying degree of pressure on the inside and outside wheels of a car, and also in the wet road condition. The SBC is found in Mercedes Benz E cars.
