20100063658 | Engine Speed Control and Battery Power Scheduling Strategy for an Engine in a Hybrid Electric Vehicle Powertrain - A control method and system is disclosed for regulating speed of an engine in a hybrid electric vehicle powertrain that includes an electric motor and gearing. An electrical power flow path and a mechanical power flow path are established. Electrical power is coordinated with mechanical power to effect an arbitrated engine speed for a given power demand that will result in an acceptable powertrain efficiency. | 03-11-2010 |

20140350766 | HYBRID VEHICLE AND ASSOCIATED CONTROL METHOD - 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. | 11-27-2014 |
