  • Patent number: 10267246
    Abstract: An internal-combustion engine has an electronically-controlled one of a turbocharger and an exhaust-driven turbo supercharger coupled to an exhaust duct of the engine, and the engine is controlled during a shift event of a transmission coupled to an output shaft of the engine by determining a target engine speed at the end of the shift event, and controlling electrical energy supplied to an electric machine, rotatably coupled to a rotatable shaft that is rotatably coupled to the electronically-controlled turbocharger or exhaust-driven turbo supercharger, to control rotation of the rotatable shaft coupled to the turbocharger or exhaust-driven turbo supercharger to attain the target engine speed.

  • Publication number: 20180030916
    Abstract: A system and method are provided for controlling fuel rail pressure in a common rail fuel injection system. A desired rail pressure value is determined based on signals produced by one or more sensors, a feedback PCV control signal is determined based on a difference between the desired rail pressure value and a fuel rail pressure signal, a feedforward PCV signal is determined based on the desired rail pressure value, and a PCV control signal for controlling a pressure control valve fluidly coupled to the fuel rail is determined based on the feedback PCV control signal and the feedforward PCV control signal. The pressure control valve signal is correlated with the temperature of fuel exiting the pressure control valve such that operation of the pressure control valve in response to the PCV control signal results in a valve outlet orifice size which controls the temperature exiting fuel.

  • Patent number: 9623864
    Abstract: A system is provided for managing torque in a vehicle driveline coupled to an internal combustion engine and to a hybrid motor/generator. An engine control circuit provides to a transmission control circuit an engine torque value corresponding to torque applied by the engine to the driveline. A hybrid control circuit provides to the transmission control circuit a motor torque value corresponding to torque applied by the hybrid motor/generator to the driveline. The transmission control circuit controls operation of at least one friction device and controls shifting of the transmission, and also manages torque applied to the drive line by the engine and by the hybrid motor/generator based on the engine torque value and the motor torque value such that the friction device control and shift schedule instructions do not require modification to accommodate inclusion of the hybrid motor/generator in the system or exclusion of the hybrid motor/generator from the system.

  • Patent number: 9624987
    Abstract: A method and system are provided for controlling the operating temperature of a torque converter during torque converter stall conditions. The torque converter has a pump rotatably driven by an internal combustion engine and a rotatable turbine fluidly coupled to the pump. The system first determines whether the torque converter is currently in a torque converter stall condition, and, if so, determines a slip speed as a difference in rotational speeds between the pump and the turbine, determines an engine output torque limit as a function of the slip speed and a desired slip speed, and controls the operating temperature of the torque converter by limiting output torque produced by the engine based on the engine output torque limit.

  • Patent number: 9381904
    Abstract: A method and system are provided for controlling overspeeding of a vehicle carrying an internal combustion engine having one or more exhaust brake devices controllable to apply braking torque to the engine. The system may be operable determine a desired speed of the vehicle, to determine a road speed of the vehicle, and if the road speed of the vehicle exceeds the desired speed of the vehicle by more than a threshold speed, to determine a target brake torque required to reduce the road speed of the vehicle speed to the desired speed of the vehicle, and to then control the one or more exhaust brake devices to apply the target brake torque to the engine to thereby control the road speed of the vehicle to the desired speed of the vehicle.

  • Patent number: 9056607
    Abstract: The present invention provides a method of selecting an economy mode shift schedule for a transmission coupled to a motor vehicle. The method includes calculating vehicle acceleration and determining a change in accelerator pedal position. Also, a net tractive effort force of the vehicle is determined for a current gear range of the transmission. Also, the method includes comparing the net tractive effort force for the current gear range to a maximum tractive effort force for a desired gear range and selecting the economy mode shift schedule for the transmission based on the comparison. The method further includes controlling shifting between one or more gear ranges of the transmission according to the economy mode shift schedule.

  • Patent number: 8935068
    Abstract: A method of selecting a gear ratio of a transmission. The method includes measuring a current road grade with a sensing device and communicating the current road grade measurement to the controller. The controller receives a signal corresponding to a service brake input and determines a desired maximum acceleration limit of the vehicle. The method also includes calculating a predicted vehicle acceleration, measuring a current vehicle acceleration, and calculating an error value as a function of the predicted vehicle acceleration and measured vehicle acceleration. The method also computes an estimated required tractive braking effort and estimated tractive braking effort for at least one of N automatically selectable gear ratios of the transmission and selects one gear ratio of the N automatically selectable gear ratios for the operation of the transmission based on a comparison of the estimated required tractive braking effort and estimated tractive braking effort.
