  • Patent number: 9896044
    Abstract: The technology described herein provides a system and method for automatically increasing the remaining driving range of a vehicle when a low fuel or other condition is detected by altering the operating parameters of one or more vehicle systems to improve propulsion system efficiency and thereby lower fuel consumption. The vehicle range extending system is capable of altering the operating parameters of any vehicle system, including for example variable displacement settings, start-stop technology settings, and HVAC operation. The disclosed technology can also provide information to the driver, suggesting which system operating parameters should be altered to reduce the fuel consumption rate.

  • Patent number: 9174645
    Abstract: The present disclosure provides systems and methods to detect and reduce any high driveline torsional levels, such as due to the cylinder deactivation in variable displacement system engines or aggressive lock-up strategies for fuel efficiency, in automobile transmissions. The present disclosure utilizes a controller in an automobile to operate a computationally thrifty method for quickly detecting noise and vibration disturbances in the transmission. This quick detection enables fuel economic calibrations that aggressively reduce the disturbances by controlling slip in a launch device of the transmission. As problem disturbances arise, they are detected before occupants notice objectionable behavior. Once detected, the disturbances are reduced, such as by increasing launch device slip, which effectively intercepts the objectionable disturbances before they are transferred through the entire drivetrain.

  • Publication number: 20140172270
    Abstract: A system and method for reducing fuel consumption of an engine while operating a power take off. Whenever practical, the system and method will operate the engine with fewer than all cylinders when operating a power take off. Operating the engine with fewer than all cylinders will reduce fuel consumption and improve fuel economy.

  • Patent number: 8485941
    Abstract: A driver controllable low speed mode for a stop/start technology-equipped vehicle. The vehicle comprises an internal combustion engine with stop/start technology having an engine controller, a transmission connected to the internal combustion engine, and a shifter connected to the transmission and the engine controller. The shifter is operable to place the transmission into one of a plurality of operating modes, the operating modes including at least a low speed mode wherein stop/start technology is disabled. The engine controller is operable to detect vehicle operation above a speed or acceleration threshold and cause an audible chime or message to be played or a visual cue displayed to prompt the driver to deactivate the low speed mode. The engine controller is further operable to detect a sustained acceleration attempt when the transmission is in low speed mode and to disable low speed mode for a predetermined period of time upon this detection.

  • Patent number: 8095287
    Abstract: Methods and systems are described to automatically lock and unlock a front axle disconnect mechanism in an all-wheel drive (AWD) system responsive to driving conditions to reduce parasitic losses and increase fuel efficiency. A control algorithm is described which automatically determines whether the front axle disconnect mechanism should lock or unlock responsive to various sensor readings throughout the vehicle. The sensor readings relate to the driving conditions. Advantageously, the present disclosure automatically decides the best mode for optimum fuel economy while safely responding to driving conditions, and therefore removes the requirement for a driver to select the operating mode.

  • Publication number: 20030121324
    Abstract: An apparatus for measuring the level of a fluid in a chamber is disclosed. The apparatus generally includes an indicator rod and a tubular member in fluid communication with the chamber. The indicator rod is a measuring rod operable to be immersed in the fluid in the chamber to indicate the level of fluid therein. The indicator rod also includes a locking mechanism to releasably engage the flange of the tube to restrain the movement of the indicator rod. The locking mechanism selectively engages a flange or the tube to lock the indicator rod to the tube. A seal between the indicator rod and the tube seals the chamber when the indicator is secured to the tube.

  • Patent number: 6188951
    Abstract: A method for characterizing the friction losses within an internal combustion engine includes determining a start-up friction term, a mechanical friction term, a pumping loss term, and an adapted friction term to compensate for long-term frictional changes in the engine. A total engine frictional loss is determined by summing the start-up friction term, the mechanical friction term, the pumping loss term and the adapted friction term.

  • Patent number: 6085730
    Abstract: A method for improving the transient response of a multi-port fuel injection system wherein the delivery of a pulse to an injector is fragmented into a variable number of pulse fragments and the delivery of the pulse fragments to the injector is spaced throughout a respective fueling window. The magnitude and delivery angle of each of the pulse fragments is variable and depends upon the current engine operating conditions. Calculations of the magnitude of each pulse fragment are based upon a constantly recalculated total pulse width.

  • Patent number: 6055971
    Abstract: A proportional/integral/derivative control system is provided for controlling the operating parameters of a feedback system according to the difference between a measured value from a component of the system and a target set point. The control system employs a linearization curve having a plateau portion near the target set point. As the measured value approaches the target set point, smaller corrective measures are employed to minimize overshooting and fluctuations. Also, a range is established about the set point wherein no corrective measures are performed.

  • Patent number: 6029624
    Abstract: A method for bypassing a controlled quantity of airflow around a throttle body of an internal combustion engine of a motor vehicle during periods of sudden deceleration of the vehicle. The method makes use of a bypass valve having an input end in communication with an air inlet of a throttle body of the engine and an outlet in communication with an air inlet of the intake manifold of the engine. When sudden closing of the throttle is sensed, or when the throttle is closed, the bypass valve is opened to a degree sufficient to enable an additional quantity of air to flow therethrough and into the inlet of the intake manifold. The invention significantly reduces the drop in engine rpm experienced during sudden deceleration of the vehicle, to thereby substantially reduce or eliminate powertrain vibration that results during sudden deceleration.
