BMW 3: System components
The front radar sensor (FRS) or the front radar sensor long range (FRSF) is
needed to reliably detect
the vehicles in front. Consequently, adaptive recuperation is only possible with
the optional equipment
Active Cruise Control with Stop&Go function (SA 5DF).
Adaptive recuperation can be implemented on different control units. Depending
on the equipment
specification, the function is integrated in the control unit optional equipment
system SAS (with
Driving Assistant Professional (SA 5AU)) or in the DSC control unit (Active
Cruise Control with
Stop&Go function (SA 5DF) ).

Operation of the brake pedal is recorded and processed directly by the DSC
unit.
The Digital Motor Electronics (DME) assumes the central coordination between the
setpoint torque
specifications which are output by the different control units. The higher
torque request is then
forwarded to the EME for implementation. The DME also stores the driving modes
in which the
function is available and not available.

function is only available
in the HYBRID ECO PRO driving mode. The function cannot be deactivated.
