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.

     Stretch of road

    The stretch of road is evaluated by means of the navigation system data. Detected situations Top speed limitations Bends Traffic circles Off ramps/exits Turning-off priority roads Red lights*

     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

     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 eq


     Concept, General information, Safety information

    Concept Using this system, a desired speed and a distance to a vehicle ahead can be adjusted using the buttons on the steering wheel. The system maintains the desired speed on clear roads. For this purpose, the vehicle accelerates or brakes automatically. If a vehicle is driving ahead of you, the
