The MAN BrakeMatic Maximum speed control enables the downhill driving speed set by the cruise control or brake pedal to be held constant by automatically activating the continuous brakes. This relieves the driver and increases driving safety. In addition, compliance with the maximum permissible speed of 100 km/h is guaranteed.
The anti-lock braking system (ABS) uses sensors to detect the speed of every wheel during braking and adjusts the brake pressure individually at each wheel, thus preventing the wheel from locking. Vehicle directional stability and manoeuvrability remain assured even for emergency braking on a slippery roadway.
With anti-slip control (ASR), the electronic brake system (EBS) can combine ASR engine control and ASR brake control. Spinning of the drive wheels when starting or accelerating is prevented by reducing the engine torque and thus the drive slip.
For ASR brake management, the EBS control unit uses the same wheel speed sensors as for the ABS, although it only affects the drive wheels. Should only one wheel of the drive axle spin, the differential transmits the remaining drive torque to the other wheel with traction.
The MAN BrakeMatic continuous braking function starts at a speed 2 km/h higher than the speed set with the cruise control speed. When the vehicle is braked with the brake pedal on a downhill gradient, the speed is stored that was reached when the brakes were released. The set speed is maintained over downhill gradients by operating the standard intarder and retarder.
Thanks to the Maximum Speed Control (MSC), the standard continuous brakes engage and keep the vehicle below the maximum speed at all times when the maximum permissible speed of 100 km/h is reached.
The EBS electronic brake system ensures that the vehicle remains directionally stable and steerable even during emergency braking on slippery roads. The ASR prevents the drive wheels from spinning when driving off or accelerating. Wheel spinning is detected by the EBS control unit using wheel speed sensors.
