Abstract: A vehicle includes a control system that performs method of operating the vehicle. The control system includes a first motor processor associated with a first motor of the vehicle. The first motor processor receives a torque command from a vehicle motion control module, coordinates an allocation of the torque command into a first motor torque at the first motor and a transmission torque at a first transmission associated with the first motor, and controls the first motor to apply the torque command at the first motor.

Abstract: An electrical system includes a high-voltage battery pack assembly having a first cell set with a first group of energy storage cells and a second cell set having a second group of energy storage cells connectable to the first cell set. The first cell set includes at least one first battery chemistry cell and the second cell set includes at least one second battery chemistry cell. At least one switch is in electrical communication with the first or second cell set. Battery connection terminals are in electrical communication with at least one of the first or second cell sets. A controller is configured to determine an operating strategy of the high-voltage battery pack assembly and place at least one of the first cell set or the second cell set in electrical communication with the battery connection terminals in response to the operating strategy of the high-voltage battery pack.

Abstract: A system for managing an energy storage device in an electric vehicle includes a battery pack having an energy module, and a power module connected in parallel to the energy module. The energy module is adapted to generate a first current. At least one DC-to-DC (direct current to direct current) converter is adapted to receive the first current from the energy module and transmit a current, referred to herein as “DC-DC current”, to the power module. The system includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded for automated management of a set of parameters related to the battery pack, subject to a plurality of constraints. The power module is adapted to deliver a second current for powering a load in the electric vehicle. Operation of the electric vehicle is controlled based in part on the set of parameters.

Abstract: Simultaneous parallel charging of a first and second electrical energy storage devices coupled to a charge source is carried out by directly coupling the charge source to one of the first ESD and the second ESD and through a DC to DC converter to the other of the first ESD and the second ESD. The charge source provides a current that is allocated to the two ESDs by controlling the DC to DC converter. Priority of charging may be given to either ESD.

Abstract: A system for controlling a transmission state of a vehicle includes a controller connected to a first drive system and a first transmission including a gear system, a first clutch and a second clutch. The controller is configured to receive a request to change from an initial transmission state to a target transmission state when a propulsion torque is applied to the vehicle. The controller is configured to distribute the propulsion torque such that all of the propulsion torque is applied by a second drive system and the first drive system does not provide any propulsion torque to the vehicle, fully release an off-going clutch from the gear system, control a motor speed based on a rotational speed relation of the target transmission state to reduce a slip speed of the on-going clutch, and fully engage an on-coming clutch to put the first drive system in the target transmission state.

Abstract: An electric vehicle, a system and a method of operating the electric vehicle. The system includes a first motor, a drive unit between the first motor and a first axle of the electric vehicle, a second motor, and a processor. The processor is configured to receive a request for the electric vehicle, receive a torque signal from the drive unit, determine at least one of a first motor torque for the first motor and a second motor torque for the second motor based on the torque signal and the request, and apply the at least one of the first motor torque at the first motor and the second motor torque at the second motor to satisfy the request.

Abstract: A system and method for operating an electric vehicle. In another exemplary embodiment, a system for operating an electric vehicle is disclosed. The system includes a first motor and a transmission coupled to the first motor. The transmission is configured to shift gears when a speed of the electric vehicle crosses a shift threshold. The shift threshold is independent of a position of an acceleration pedal of the electrical vehicle.
