摘要： A method for setting a shift point for shifting a transmission for a powered vehicle between a first gear ratio and a second gear ratio. The method includes determining input power data points based on real-time input torque data. The input torque data includes a maximum input torque. The method also includes calculating a gear step value based on the first gear ratio and second gear ratio. The method further includes determining a first power value and computing a second power value based on the gear step value. The first power value and second power value are compared to one another and adjustments are incrementally made in the first power value speed until the difference between first and second power values meets a threshold. The shift point is therefore based on the result of comparing the first power value and the second power value and the corresponding speed associated with the first power value.

摘要： A powertrain waste heat recovery system includes a first powertrain component and a second powertrain component. The powertrain waste heat recovery system also includes a heat recovery circuit circulating a heat recovery fluid through a heat recovery heat exchanger. The heat recovery heat exchanger transfers heat from the first powertrain component to the heat recovery fluid during a powertrain propulsion mode and transfers heat from the second powertrain component to the heat recovery fluid during a powertrain retarding mode. The powertrain waste heat recovery system also includes a conversion device for converting thermal energy from the heat recovery fluid to an energy form other than thermal energy.
