Using an EBS electronic braking system enables optimisation of the drive and braking operations on commercial vehicles. An electropneumatic brake, ABS Anti-lock Braking System and TCS Traction Control System are integrated as basic functions within EBS. Electronic adjustment of the braking force in each respective braking situation can also reduce the wear in associated components – thus improving the cost-effectiveness of the entire braking system. It also facilitates monitoring and maintenance of the braking system.
The EBS electronic brake system operates via an electronic control signal from the brake pedal sensors that is electronically processed in the EBS control unit and then sent to the pressure control modules with practically no time delay. The pressure control modules pneumatically adjust the required brake pressure in the wheel cylinders and simultaneously send the sensor signals from the wheel area to the EBS control unit. The traction between tyres and road surface can be exploited up to the maximum limit value. The pneumatic working circuits for actuating the brake cylinders in the towing vehicle and trailer are established in the same way as the dual-circuit dual-line braking system. The EBS reverts to a pure compressed air braking system with two compressed air circuits in the event of faults. Pressure is then built up in the brake cylinders when braking, without control depending on the position of the brake pedal. Electronic and therefore instant activation of the brakes via the pressure control modules enables the driver to experience a similarly direct braking sensation as in passenger cars.
