Dynamic stability control DSC Mk60
E85
Introduction
The E85 is equipped as standard with dynamic stability control Mk60. DSC Mk60 was first introduced on the E46 in
09/2000, but without DTC function (DTC = dynamic traction control). From 09/2000 to 09/2001 DSC in the E46 was
equipped with the ADB function (automatic differential brake). From 09/2001, DSC Mk60 has been available in the
E46 with DTC function.
System supplier for DSC Mk60 is Continental Teves. [System overview ...]
DSC is a dynamic driving system that maintains driving stability.
DSC optimises:
-
driving stability when pulling away, accelerating and braking
-
traction
In addition, DSC recognises unstable driving situations such as understeering or oversteering. Within the limitations
of the laws of physics, DSC helps to keep the vehicle on a safe course.
To do this, DSC must know the following parameters of driving dynamics:
-
yaw rate as a measure of rotary movement of the vehicle around the vertical axis
-
lateral acceleration as a measure of the coefficient of friction with the road surface
-
road speed
In addition, the driver's requirements are recognised from the angle of the steering wheel and the pressure on the
brake pedal. Moreover, speed sensors deliver information about the speed of each individual wheel. The actual
situation in which the vehicle is currently moving is computed from the available data. The actual situation is
compared to reference data computed by the DSC control unit.
