Itnis a control device for anPowertrain system provided, which includes a machine and two electric motorsnincludes, which are functionally combined with a power-split,ncoupled electromechanical two-mode transmission. it includesna system controller and two engine control processors. The system controllerncommunicates with the engine control processors via two high-speed communication busesnand directly connected serial peripheral interface buses. ThenMotor control processors control a flow of electrical powernbetween the electric motors and a storage device for electricalnEnergy. A second controller is operable to power the machinencontrol, preferably to control the output torque. ThenInternal combustion engine preferably has a crank position sensornon, the signal-wise with a dedicated input in the secondnControl device and with a dedicated input to the system controllernthe first control device is connected. |
