New functions for DSC:
Brake Standby through pre-tensioning of the brakes in an emergency
Pre-tensioning the brakes shortens the brakes' response time.
If the accelerator pedal is rapidly released (accelerator pedal angle), the brakes are immediately pretensioned.
DSC generates a low brake pressure without a measurable deceleration taking place.
The clearance between the brake pads and brake discs is eliminated. If the brakes are not applied within half a
second, the brake pressure that was generated early is reduced again. The pre-tensioning of the brakes
depends is active at speeds greater than 70 km/h.
Brake disc drying on wet roads
Braking dry removes moisture that gathers on the brake discs during journeys on wet roads or in rain.
The brake pads are lightly applied. This function also shortens the brakes' response time.
Depending on the signal from the rain sensor and the position of the wiper switch, DSC cyclically generates a
low brake pressure. This creates no measurable deceleration on the vehicle. The brake pads are cyclically
applied. This means that the brake disc are regularly wiped down. How often and how long the brake pads are
applied depends on:
•
The intensity of the rain, e.g. the speed of the windscreen wiper
•
Road speed greater than 70 km/h
Fading compensation
Fading means: braking effect deteriorates as a result of high brake-disc temperatures.
If fading is detected, DSC reacts by increasing the brake pressure above that specified by the driver.
At very high brake-disc temperatures, fading compensation is indicated by the following:
•
General brake warning lamp lighting up yellow
•
Check-Control symbol in LCD display in instrument cluster lighting up yellow
(not E83)
DSC detects fading as follows: DSC compares the current vehicle deceleration with a nominal value based on
the current brake pressure.
DSC increases brake pressure until the nominal deceleration is achieved or until all wheels are subject to ABS
control. The process is ended when the brake pedal is no longer depressed or when the speed drops below a
certain threshold.
Soft stop when braking to standstill (not on BMW 3-Series all-wheel drive or E83)
