  • Patent number: 9592817
    Abstract: A system and method for controlling energy distribution within a HEV powertrain are provided. A feedforward battery power value is generated in response to input indicative of a driver torque request. A feedback battery power modification value is generated in response to input indicative of actual battery power and the driver torque request. A battery power request is calculated based a sum of the feedforward battery power value and the feedback battery power modification value.

  • Publication number: 20160268944
    Abstract: A vehicle includes an electric machine and a controller configured to inject a voltage into the electric machine. The controller measures the currents caused by the voltage and processes the currents using a discrete Fourier transform to determine positive and negative sequence currents. A phase rotation sequence is identified by comparing the sequence currents to expected positive and negative sequence currents that are associated with possible phase rotation sequences. The electric machine may be controlled according to the identified phase rotation sequence. A cable swapped diagnostic may be output when the phase rotation sequence is different than an expected phase rotation sequence.

  • Patent number: 9409566
    Abstract: A hybrid vehicle and method of control are disclosed wherein the ratio of engine speed to vehicle speed varies continuously in some operating modes and is controlled to simulate a discrete ratio transmission in other operating modes. The disclosure specifies the method of controlling the engine speed and the combined output torque of the engine and at least one traction motor in each of the operating modes. Transitions among operating modes occur in response to driver movement of a shift lever, driver operation of shift selectors, and changes in vehicle speed.

  • Patent number: 9361272
    Abstract: A vehicle powertrain controller includes a fuzzy logic-based adaptive algorithm with a learning capability that estimates a driver's long term driving preferences. An adaptive algorithm arbitrates competing requirements for good fuel economy, avoidance of intrusiveness and vehicle drivability. A driver's acceptance or rejection of advisory information may be used to adapt subsequent advisory information to the driving style. Vehicle performance is maintained in accordance with a driver's driving style.

  • Publication number: 20160156290
    Abstract: A power inverter for driving an electric machine is configured to apply a voltage to the electric machine based on a high-frequency injection current. Three phase currents are measured and input into a current controller. A voltage command output from the current controller is monitored using a discrete Fourier transform to determine a positive and negative sequence voltage of the voltage command. The sequence voltages are compared to expected positive and negative sequence voltages. A loss of connection diagnostic is output if a magnitude of the difference between the expected and actual sequence voltages is greater than a predetermined threshold.

  • Patent number: 9187085
    Abstract: A plug-in hybrid electric vehicle operates the engine and/or traction motor in response to energy costs or prices received from an external source, such as a user or network. The vehicle can include a battery; an engine; an electric motor; a memory to store a battery charge point, and a controller to modify the battery charge point in response to arbitration criteria to control battery charging from the engine. The arbitration criteria can be based at least partially on fuel cost for the engine. The arbitration criteria can be based at least partially on electricity cost. The arbitration criteria can also include location of the vehicle. The controller may alter a deadband between charging the battery with the engine and discharging the battery to power the traction motor based on the arbitration criteria.
