The�EDME�control�unit�contains�the�logics,�i.e.�the�preconditions�when�the�parking�lock�is�to�be
engaged�or�disengaged.�Via�the�PT-CAN�the�EDME�control�unit�sends�the�corresponding�commands
to�the�electrical�machine�electronics.

The�EME�control�unit�activates�the�parking�lock�actuator�directly.�It�behaves�similarly�with�the�function
of�the�other�drive�positions�"R"�and�"D".�Also�here�the�EDME�control�unit�calculates�the�logic�part.
The�electrical�machine�electronics�is�responsible�for�the�implementation,�for�example�to�activate�the
electrical�machine�for�reversing�or�forwards�travel.�Finally,�the�transmission�of�the�I01�also�offers�the
functions�shift�lever�interlock�and�interlock,�whose�logic�part�is�also�calculated�in�the�EDME�control�unit
(see�section�"Shift-by-Wire�function").
