Patent attributes
A vehicle with an N-phase electric motor, with a first onboard electrical subsystem and with a second onboard electrical subsystem, wherein the electric motor includes a rotor and a stator system, and the first onboard electrical subsystem includes an inverter. The stator system is associated with the inverter and the electric motor is operable with an inverter controller according to the principle of field-oriented control such that the stator system is embodied in a star circuit in which the star point can be connected to the second onboard electrical subsystem directly or via a star point switch. The inverter controller includes a current controller and a star point controller, wherein the current controller controls phase currents of the stator system and the star point controller controls a star point current.
