Energy recovery
Anticipatory hybrid drive
Principle
Principle
With energy recovery, also called recuperation,
the electric motor acts as an alternator and
converts the vehicle's kinetic energy into elec-
trical energy when braking and coasting.
This system ensures the optimal distribution
of available electric power so that the vehicle
can be driven electrically when using the navi-
gation system’s route guidance in urban areas
and near the destination. If the high-voltage
battery is sufficiently charged, additional seg-
ments of the route will be selected for electric
drive.
This recovered energy charges the high-volt-
age battery. If necessary, this stored electrical
energy is output to the electric motor.
General information
General information
Downhill gradients, for example, are taken into
account to ensure efficient energy recovery.
Depending on the M Setup menu settings:
The high-voltage battery is charged at differ-
ent speeds, and the vehicle is decelerated at
different forces while coasting.
Depending on the route section, the combus-
tion engine is automatically switched on or off,
which supports an efficient driving style and
emission-free driving in the inner city.
Setting Description
"MIN"
Setting for low energy recovery.
Depending on the route and driving style, this
function may affect the overall energy con-
sumption.
"MAX" Setting for maximum energy recov-
ery.
If the vehicle is set to electric drive, the hybrid
drive turns on automatically if the route to
be driven is longer than the available electric
range. This ensures that the electric drive is
planned efficiently when using anticipatory hy-
brid drive.
Energy recovery settings can be configured in
the M Setup menu. Additional information:
M Setup, refer to page 210.
Functional requirements
Conditions such as the following prerequisites
must be met to recover kinetic energy:
If a situation requiring greater acceleration is
expected, the combustion engine may start
automatically, depending on the engine, in or-
der to prepare for this acceleration.
▷
▷
▷
The vehicle is moving.
Selector lever position D/S is set.
The high-voltage battery is not fully
charged.
Functional requirements
▷
The function must be available in the coun-
try in which the vehicle is driven.
Support from the electric motor
During normal driving, the electric motor as-
sists the combustion engine, depending on the
situation.
▷
▷
▷
▷
Selector lever position D is engaged.
Route guidance is enabled.
SPORT driving mode is not activated.
eCONTROL mode is deactivated.
Accelerating quickly such as when passing re-
quires the maximum available power from the
electric motor. To do so, press the accelerator
pedal firmly.
