  • Patent number: 10782145
    Abstract: Vehicles, systems, and methods for determining a distance travelled are provided. In an exemplary embodiment, a vehicle includes an electric motor with a motor rotor shaft. A motor resolver is positioned adjacent to the motor rotor shaft, where the motor resolver is configured to determine a motor position of the electric motor based on revolutions of the motor rotor shaft. A controller is in communication with the motor resolver, where the controller is configured to determine a distance travelled from a change in the electric motor position.
    Type: Grant

  • Patent number: 9914448
    Abstract: A powertrain assembly has multiple torque actuators. The assembly includes a first controller configured to control a first torque actuator and a second controller configured to control a second torque actuator. The first controller is configured to receive a signal from an input sensor and convert the signal into a torque demand. The second controller is configured to receive the torque demand from the first controller and determine respective optimal torque allocations for the first and second torque actuators based on the torque demand and a plurality of optimization factors. The first controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of controlling the multiple torque actuators across the at least two controllers via a dynamic look-up table. The dynamic look-up table is populated by a plurality of stored torque production allocation values based on a respective plurality of torque requests.
