BMW 3: Route guidance
Adaptive recuperation uses the data and calculations of the route-ahead assistant. In this way, adaptive recuperation can be used by the navigation system when route guidance is both active and not being used. When the route guidance is not active, the most likely route is used for evaluation.
However, the stretch of road can be calculated more accurately, and therefore more efficiently, when the route guidance is active.
Decelerations
The following diagram shows the extent of the energy recovery with and without adaptive energy recovery depending on the speed. The brake lights are not activated automatically during recuperation.

G20 PHEV comparison of deceleration with and without adaptive recuperation
- Vehicle with adaptive energy recovery (example: G20 PHEV)
- Vehicle without adaptive energy recovery (example: G12 LCI PHEV)
- Deceleration by recuperation
- Control range of adaptive recuperation
- Control of recuperation in HYBRID ECO PRO driving mode
- Control of recuperation in HYBRID STANDARD driving mode
- Vehicle speed
To illustrate this: -0.1 g (-0.981 m/s2) corresponds to a speed reduction of approximately 2 mph (3.5 km/h) per hour.
Deceleration to a standstill does not happen since in the low speed range the vehicle is driven via the automatic transmission (creeping).

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

Displays and operation
The function does not have any separate display or operating elements. The
function is only available
in the HYBRID ECO PRO driving mode. The function cannot be deactivated.

Concept
The system assists the driver in keeping the vehicle
within the lane. For this purpose, the system
executes supporting steering movements,
for instance when driving in a curve.
