The central module exchanges EBS system bus related data with the axle modulators. Moreover, the wheel velocity is evaluated so that in case of locking, an ABS control can be carried out by modulating the braking pressure in the brake cylinders. The front axle’s nominal pressure value is then compared with the measured actual value, and any existing deviations corrected with the help of the proportional relay valve. The nominal delay and the wheel velocity measured by the speed sensors are input signal for the electro-pneumatic control unit, which uses it to calculate nominal pressure values for the front axle and rear axle(s). It determines the vehicle’s nominal delay from the signals received by the brake signal transmitter. The central module is used to control and monitor the electronically controlled braking system.
In terms of wheel brake service costs alone, a firsthand owner will save more money with an electronically braked bus than with a vehicle with a conventional braking system. This reduces down-time costs.ĭepending on the vehicle utilisation profile and other factors, this also means considerable savings for the vehicle user. Moreover, servicing and lining replacement are done at the same time. Overall wear is minimised by making the load on all wheel brakes uniform. Setting pressure, according to wear criteria, to the front and rear axle results in uniform lining wear. The aim is to maximise braking safety at reduced costs, for instance by optimising wheel brake lining wear. The electronic braking system has a lot of functions.
The full diagnosis and surveillance functions as well as the display of brake lining wear offer an effective fleet logistics. Therefore, the development and introduction of an electronic braking system (EBS) is a logical step.ĮBS increases traffic safety through reduced stopping distance and improved brake stability. The demands made on braking systems are increasing steadily. 17 Halt brake, brake hold and release aid. 14 Additional redundancy on the front axle.
