  • Method for controlling a vehicle powertrain having step ratio gearing and a continuously variable transmission to achieve optimum engine fuel economy
    Patent number: 7789795
    Abstract: A method is disclosed for controlling overall transmission ratios in a vehicle powertrain with an engine, fixed multiple-ratio gearing and infinitely variable ratio components. For a given vehicle speed and for a given vehicle traction wheel horsepower, the fixed multiple-ratio gearing and the infinitely variable ratio components are controlled to operate with an overall ratio that will permit the engine to operate with optimum efficiency.
    Type: Grant

  • Method of estimating vehicle deceleration during a transmission gear shift
    Patent number: 6691011
    Abstract: A method for estimating deceleration of a wheeled vehicle during a transmission gear shift. A first input signal indicative of an engine torque and a second signal indicative of an input shaft rotational speed are used to predict the expected vehicle deceleration during a transmission ratio shift to a target gear ratio. An expected vehicle deceleration value is outputted to a shift decision control unit for implementing a transmission gear shift.
