  • Patent number: 10047860
    Abstract: A target module determines a target ratio between a speed of an input shaft and a speed of an output shaft of a continuously variable transmission (CVT) based on an accelerator pedal position. A maximum rate of change (ROC) module determines a maximum ROC of the target ratio. A switching valve control module, based on a comparison of the maximum ROC and a ROC of the target ratio, selectively actuates a switching valve of the CVT one of (i) from a closed position to an open position and (ii) from the open position to the closed position. The switching valve prevents transmission fluid flow through a flow path between a transmission fluid pump and a pressure regulator valve of the CVT when the switching valve is in the closed position. The switching valve allows transmission fluid flow through the flow path when the switching valve is in the open position.

  • Patent number: 10040029
    Abstract: A method is disclosed of providing a fuel efficient regeneration of an exhaust after-treatment (AT) system that includes a lean oxides of nitrogen (NOX) trap (LNT) and a selective catalytic reduction filter (SCRF) positioned downstream of the LNT. The method includes regulating a selectable position valve. The valve permits a first gas flow portion to pass through the LNT and diverts a remaining second portion of exhaust gas flow from a first passage connecting an engine and the AT system to a second exhaust passage to thereby bypass the LNT. The method also includes regulating a first device to inject fuel into the first portion of the exhaust gas flow. The injection of fuel in to the first portion of the exhaust gas flow provides fuel efficient regeneration of the LNT and promotes NOX conversion and ammonia (NH3) formation in the LNT. A system employing the method is also disclosed.

  • Patent number: 10040439
    Abstract: A powertrain system employing multiple propulsion torque actuators is described. A method for controlling the powertrain system includes interpreting a driver request, including determining a driver torque request and a regenerative braking request based upon driver inputs to an accelerator pedal and a brake pedal. A desired request is determined based upon the driver torque request and the regenerative braking request. Torque limits for the powertrain system are coordinated based upon the desired request, the driver torque request, and a previous driver torque request to determine upper and lower output torque limits, and the upper and lower output torque limits are combined with system constraints to generate a final torque request. The final torque request is employed to determine torque commands for the propulsion torque actuators, and the propulsion torque actuators are controlled based upon the torque commands for the propulsion torque actuators.

  • Patent number: 10040460
    Abstract: A system and method for computationally estimating a directional velocity of a vehicle in real time under different configurations and road conditions for use in vehicle antilock braking, adaptive cruise control, and traction and stability control by correcting measured accelerations with respect to the estimated road angles. A time window is used to provide reliable mapped acceleration for the transient regions and maneuvers on gravel surfaces with high fluctuations in the acceleration measurement. Longitudinal and lateral accelerations are mapped from the vehicle's CG into the tire coordinates using the vehicle's geometry, lateral velocity, yaw rate, and the steering wheel angle to generate system matrices of the combined kinematic-force estimation structure.

  • Patent number: 10041586
    Abstract: A vehicle includes a prime mover, a transmission having an electronic transmission range selection (ETRS) system, a user interface device that generates an electric range selection (ERS) signal in response to a selected operating range, and a controller. The controller processes the ERS signal and determines the operating range and executes a remedial control action when the incorrect powerflow is detected. The remedial action may include interrupting powerflow. A control apparatus includes the user interface device and controller. A method includes determining if a powerflow fault condition is present, including comparing clutches commanded on against a calibrated list of clutches not permitted to be on, and one or both of comparing a measured speed ratio to an expected speed ratio and comparing actual switch states of mode valves to states commanded by the ETRS system. The method includes executing the remedial control action when the incorrect powerflow is detected.

  • Patent number: 10042047
    Abstract: In an embodiment, a method for processing a sequence of images is provided. The method receives a sequence of images generated by a radar. Each image includes a plurality of pixels. Each pixel includes radial velocity information. The method estimates optical flow for the pixels within an image in the sequence of images by using the radial velocity information for the pixels as a constraint.

  • Patent number: 10041589
    Abstract: A speed ratio containment process limits the speed ratio of a variator for a CVT for a motor vehicle when rolling backward by commanding a speed ratio that is higher than the actual speed ratio in an overdrive direction. Accordingly, the actual speed ratio moves to a lowest limit, which provides maximum torque when a driver of the motor vehicle steps on the accelerator pedal to resume forward motion of the motor vehicle.
