BMW 3: Introduction
Adaptive recuperation is used in the G20 PHEV. Here, the application and extent of coasting recuperation (and the resulting vehicle deceleration) is adapted intelligently and depending on the traffic situation and the stretch of road. The function decides automatically whether the vehicle coasts or regenerates power (recuperates).
In this way, the driver is supported in anticipatory driving and energy recuperation is optimized.
Furthermore, comfort is enhanced by the reduced number of brake pedal operations.
Adaptive recuperation is not a separate item of optional equipment. It is available as a function in the HYBRID ECO PRO driving mode.
Functional principle
The aim of adaptive recuperation is to use the vehicle's kinetic energy appropriately for the situation and thus more intelligently. The traffic situation in front of the vehicle and the stretch of road ahead are evaluated for this purpose. The following events are taken into consideration:
Traffic situation in front of the vehicle
Evaluation of the traffic situation in front of the vehicle is effected, depending on the equipment specification, via the respective variant of the KAFAS camera and the front radar sensor.

Route guidance

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

Concept
In the event of an accident, the system can bring
the vehicle to a halt automatically without intervention
by the driver in certain situations. This
can reduce the risk of a further collision and the
consequences thereof.
At standstill
After coming to a halt, the brake is released automatica
