Abstract: a motor vehicle includes a multiphase ac electric motor having a stator wound with a first stator winding set including three phases and a second stator winding set including three phases, the three phases of the first stator winding set and the three phases of the second stator winding set wound oppositely to one another in the stator. additionally, the motor vehicle includes a source of stored electrical energy and an inverter coupled to the source of stored electrical energy and to the electric motor to provide switched electrical energy to the first stator winding set and the second stator winding set. in addition, the motor vehicle includes a driver configured to simultaneously switch a relatively high side of the inverter to a first phase of the first stator winding set and a relatively low side of the inverter to a corresponding first phase of the second stator winding set.

Abstract: a method includes transmitting a first wireless communication from a user device via an authorized first cellular network. the first wireless communication includes a current geographic location of the user device. the user device maintains a forbidden list identifying unauthorized cellular networks. based on determining that the user device is approaching a geofence between a first network coverage area of the first cellular network and a second network coverage area of a second cellular network that is identified on the forbidden list, the method includes removing the second cellular network from the forbidden list. with the second cellular network removed from the forbidden list and based on the user device entering the second network coverage area, the method includes transmitting a second wireless communication from the user device via the second cellular network that includes an updated geographic location of the user device.
