Automatic Soft Stop
Due to the transition from sliding friction to static friction on the brake disc, a stopping jolt
occurs when braking to a standstill where the occupants perceive an increased feeling of
deceleration.
When braking lightly (< 25 bar) at constant pressure to bring the vehicle to a halt, the soft
stop function automatically reduces the braking pressure at the rear axle just before the
vehicle comes to a stop. This consequently reduces the positive acceleration peak per-
ceived by the occupants by approx. 50% while extending the action time.
The speed and standstill status are recognized by way of the wheel speed sensors.
Note: This function is inactive at medium to high deceleration or in the event of
ABS control in order not to lengthen the stopping distance.
