Carmaker quick start lesson 4 developing 48V P1 hybrid system

This lecture shows how to create 48V P1 Hybrid cars , The example in this case is ：DemoCar.

4.1 establish 48V Hybrid P1

load DemoCar.Main GUI > Car > Select, choice ProductExamples > Examples > DemoCar.

Change the layout of power system from traditional power system to P1 Hybrid power system . Parameters > automobile > dynamic system . Right click anywhere in the window , Select the parallel hybrid system -> P1 -> Automatic manual transmission .

Want to keep the traditional engine , Just add a stronger starter generator .

Go to the power source , Select the starting motor . stay " routine " The transmission ratio is set in the tab , Change it to 1（ Directly on the crankshaft ）.

In the tab marked with torque , Change the mechanical power to 12 kW, The maximum torque is changed to 130 Nm, The maximum speed is changed to 8000 rpm.

chart 4.1： Parameter setting of starting motor

After determining the hardware of the power source , Then adjust the control strategy . Because the torque of electric motor is large , Therefore, the accelerator pedal and torque regulator must be changed . Now the maximum torque when full of oil should be 315 Cattle meters （ Internal combustion engine 185 Cattle meters , Electric motor 130 Cattle meters ）.

Click on  " control unit ", And then click  "PT control ", It's marked with  "Gas " In the tab , Change the maximum torque at full oil to 315 Cattle meters .
