    Abstract: A system and associated methods for controlling valve motion in internal combustion engines provide a pulsing component for energizing a solenoid control valve in pulsatile fashion to cause a transient pressure change in a hydraulic network linking the control valve to a common, paired set of intake and exhaust main event deactivation mechanisms, which may be provided in respective valve bridges. The pressure change results in hydraulic deactivation of main event motion of the exhaust valve while avoiding deactivation of main intake event motion and thereby preserving intake main event valve motion, and supporting use of the intake main event motion for additional braking or other operations. The systems and methods are particularly suited for engine environments that employ cylinder deactivation (CDA) combined with high-power density (HPD) engine braking.

  • Patent number: 10465615
    Abstract: Methods and systems are provided for cooling an engine by operating an electrically driven intake air compressor. In one example, in response to a determination, based on a measured or inferred engine temperature, that the engine temperature is greater than a threshold temperature, employing the vehicle's electrically driven intake air compressor to route air through a charge air cooler and engine cylinders, while engine spins unfueled. In this way the engine temperature may be reduced even under conditions not normally amenable to engine cooling, such as at idle-stops or when an engine coolant system is degraded.

  • Patent number: 10408183
    Abstract: Systems and methods for restarting an engine are presented. In one example, an engine may be automatically stopped and started in response to thresholds that may be adjusted as a distance traveled by the vehicle increases. The thresholds may be adjusted responsive to useful life consumed of an engine starter that may participate in automatic engine starting and stopping.

  • Patent number: 10402772
    Abstract: Electronic components may be integrated in objects used by the trucking industry, such as truck, tractor trailer, cargo, and loading bay. These objects may then communicate with each other and with a gateway device to transmit or receive data or commands. The gateway may be configured to attach to the truck, such as by securing to the truck frame or securing to an interior of the truck cab. The gateway may couple to one or more input devices, and receive sensor data through the one or more input devices. The gateway may execute steps that allow the gateway to perform geofencing to prevent conflict between cargo in the vehicle and cargo in another vehicle or in areas of a loading bay.

  • Patent number: 10221822
    Abstract: A vehicle and method of controlling a vehicle having an engine and braking system having an associated braking pressure include stopping the engine responsive to the brake pressure being above a first threshold, restarting the engine responsive to the brake pressure falling below a second threshold, reducing the second threshold for a predetermined time after the vehicle speed falls below a speed threshold, and resetting the second threshold after the predetermined time. The predetermined time may be modified based on input from a user interface or a user-selected vehicle operating mode.

  • Patent number: 10214107
    Abstract: An ECU includes: a control section for controlling an engine such that the engine is operated in an intermediate load state during electric power feed to the outside of a vehicle; a learning section for learning a control parameter based on a detected state quantity; and a determination section for determining whether a learning condition that the learning section learns the control parameter is established. When the learning condition is established during the electric power feed from the electric power feed section to the outside of the vehicle, the engine is controlled such that a state thereof is changed from the intermediate load state to either an idle state or a low load state, and the control parameter regarding the engine in the idle state or the low load state is learned.

  • Patent number: 10138770
    Abstract: An electronic control unit stores a vehicle load at the time when the vehicle is switched into an ignition off state, stops operation of an electric oil pump when the vehicle load is small, and operates the electric oil pump when the vehicle load is large. Thus, a decrease in service life due to an increase in the number of times of the start of the electric oil pump is suppressed, and, when it is estimated that the vehicle load is large, the response of the start of a vehicle, which makes a driver experience a feeling of strangeness, is improved by starting the electric oil pump together with switching the vehicle into an ignition on state.

  • Patent number: 10138858
    Abstract: An engine control method includes determining an intention of a driver for acceleration during vehicle traveling, stopping fuel supply to an engine when a determination is made that the driver does not have the intention for acceleration, detecting a speed of the vehicle during inertial traveling, with fuel supply to the engine kept stopped, permitting restart of the engine when a determination is made that the driver has the intention for acceleration after stopping the fuel supply to the engine, prohibiting the restart of the engine until an engine rotational speed drops to or below a predetermined rotational speed threshold, even when the restart of the engine is permitted, restarting the engine after the engine rotational speed drops to or below the predetermined rotational speed threshold, and changing the rotational speed threshold depending on the detected speed. The rotational speed threshold increases with increase in the detected speed.
