So, after a while  I solved the problem.
I bought a Voltage controlled PAS from china, and its working pretty good.
Also I had a Problem with the Maximum Speed here in Germany...we are allowed max 25Kph  with Pedelec Mode. NO throttle allowed.
I build a little electronic switch for this.
There are following things included...
1. COP MODE  

      After Power on, the Bike is driving max 25kph with Pas ..
2. unlocked Mode    There is a hidden pushbutton switch, after pushing it, the COP MODE is off, the Motor gives full power at PAS Mode.
3. Full Power Button    A second hidden mikrobutton, that gives full throttle, when pushing it.  useful at traffic lights, for kickdown  

4. I use a backback for my battery, if I dismount of the bike I disconnect the power, after Power on the system, the cop mode is activated.
