Driver convenience is further enhanced, as
fewer accelerator and brake pedal operations
are required. Speed restrictions and safety
factors are reliably observed and the flow of
traffic thus better regulated.
ACC (Adaptive Cruise
Control)
Adaptive Cruise Control is a new system
designed to assist drivers and offers a much
wider range of functions than the
conventional Tempomat.
Running Gear
If the distance is less than desired, the vehicle is
decelerated by reducing power, changing gear
and if necessary applying the brakes.
In the interests of comfort, maximum possible
braking is restricted to approx. 25 % of the
maximum deceleration potential of the brake
system (full braking).
The control action is designed to assist the
driver and thus contributes to greater road
safety.
In certain traffic situations, active braking by the
driver may still be necessary. Summary of Adaptive Cruise Control (ACC)
The basic Adaptive Cruise Control function is
to maintain a driver-selectable distance from
the vehicle in front. ACC thus represents the
logical next step on from the original cruise
control system.
The distance from and speed of the vehicle in
front are determined by a radar sensor. If the
distance is greater than desired, the vehicle is
accelerated until the required speed input by
the driver is achieved.
