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

Cross traffic warning
Concept
At blind driveways or when driving out of diagonal
parking spaces, approaching cross traffic is
detected sooner by the system than is possible
from the driver's seat.
