Introduction
The Electrical Machine Electronics (EME) is primarily used as control
electronics for the electrical
machine. It is also responsible for converting the direct current voltage from
the high-voltage b

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.
