The firm — Mercedes-Benz producer for the first time among global car makers developed the system operated by electronics for reduction of length of a brake way in case of emergency. It is called Brake-Assist, since 1997 the system is installed serially (fig. 8.4).
On the nature of pressing a brake pedal the Brake-Assist system distinguishes situations of emergency brake application on the speed of pressing a pedal. From this point the management with ensuring the most effective braking of the electronic engineer undertakes until the driver does not begin to control effort to brake pedals.
During fractions of a second the brake effort increases because in the modern brake system with the Brake-Assist system the main cylinder and the amplifier are also equipped with electronic elements and are included in the scheme of electronic control by system, and the brake way of the car at a speed of 100 km/h is reduced by 45%.
