Electrical￿Digital￿Motor￿Electronics￿EDME
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.
Electrical￿machine￿electronics￿(EME)
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").
