  • Systems and methods for engine cooling during S/S events
    Patent number: 10774725
    Abstract: Methods and systems are provided for reducing temperature of an engine or single cylinder(s) of the engine at start/stop events where the engine is stopped from combusting air and fuel, and in response to an overheating engine condition. In one example, a method comprises activating an electric air compressor to direct cooling air flow through a first single cylinder of the engine, to reduce a temperature of the first single cylinder to a desired temperature prior to a request to restart the engine. In this way, a single cylinder indicated to be overheating may be effectively cooled, without employing methodology that would otherwise cool the engine as a whole, which may thus prevent engine degradation and which may conserve power of an onboard energy storage device.

  • METHODS AND SYSTEMS FOR EXHAUST TUNING VALVE DIAGNOSTICS
    Publication number: 20200276969
    Abstract: Methods and systems are provided for diagnostics of an exhaust tuning valve during vehicle-off conditions. In one example, the engine may be reverse rotated, unfueled while the position of the exhaust is varied and an intake air flow is estimated at each position of the exhaust tuning valve. The exhaust tuning valve may be diagnosed based on a change in air flow with the variation in the position of the exhaust tuning valve.

  • ON-BOARD DIAGNOSTIC MONITOR PLANNING AND EXECUTION
    Publication number: 20200273262
    Abstract: A first controller receives a diagnostic recommendation from a cloud server. A second controller, in communication with the first controller over a vehicle bus, responsive to occurrence of a vehicle condition triggering execution of an on-board diagnostic (OBD) monitor, suspends the execution of the OBD monitor while the vehicle is within a region specified by the diagnostic recommendation. Locations in diagnostic result data are correlated to identify clusters of locations that include at least a predetermined number of executions of an on-board diagnostic (OBD) monitor. Responsive to a predicted probability of success of execution of the OBD monitor for one of the clusters of locations computed using the diagnostic result data being below an enablement threshold, a message is sent to a vehicle suspending further executions of the OBD monitor at the location.

  • Systems and methods for conducting onboard engine cleaning routines in a vehicle
    Patent number: 10753294
    Abstract: Methods and systems are provided for reducing carbon buildup in an exhaust gas recirculation system of an engine of a vehicle. In one example, a method comprises injecting a diesel exhaust fluid into an intake manifold of the engine, routing the diesel exhaust fluid into the exhaust gas recirculation system, and vaporizing the diesel exhaust fluid in the exhaust gas recirculation system. In this way, any carbon deposits associated with an exhaust gas recirculation valve and/or exhaust gas recirculation passage may be reduced, which may increase fuel economy and may reduce undesired emissions.

The method may be responsive to drone recharge energy cost being greater than a predefined threshold and include commanding a processor of the drone to execute actions that preclude the drone from recharging. The method may also be responsive to drone charge level falling below a charge threshold selected only while the drone recharge energy cost exceeds the predefined threshold and include commanding the processor to execute actions to recharge the drone.

  • Systems and methods for reducing vehicle emissions
    Patent number: 10746135
    Abstract: Methods and systems are provided for taking mitigating action where a canister purge valve configured to control an amount of fuel vapors inducted into the engine during purging operations of a fuel vapor storage canister, is indicated as being degraded. In one example, a method comprises controlling an amount of pressure directed to a fuel tank and the fuel vapor storage canister via a pump positioned downstream of the fuel tank and canister to actively route fuel vapors to the canister during a refueling event. In this way, fuel vapors may be prevented from being routed to engine intake under conditions of a degraded canister purge valve, which may reduce opportunity for vehicle stall, improve driveability, and which may reduce release of undesired evaporative emissions to atmosphere.

  • Systems and methods for turbo wastegate diagnostics
    Patent number: 10746093
    Abstract: Methods and systems are provided for indicating whether a wastegate positioned in a vehicle exhaust system is stuck in a closed or open configuration. In one example, a method comprises activating an electric air compressor positioned in an intake of the engine and obtaining a first baseline air flow and a second baseline air flow in the exhaust system, and in response to an indication that the wastegate is potentially stuck open or closed, obtaining a test air flow measurement via activating the electric air compressor and comparing the test air flow in the exhaust system to the first and/or the second baseline air flow. In this way, the wastegate may be diagnosed under conditions of limited engine operation, such as that which may occur in hybrid electric vehicles.

  • Method and system for NVH control
    Patent number: 10746112
    Abstract: Methods and systems are provided for reducing driver dissatisfaction from NVH associated with cylinder deactivation. Audio and video feed is captured from inside a vehicle and analyzed to infer if a vehicle operator is distracted. If yes, then a VDE transition is scheduled to occur during the time when the driver is distracted and unlikely to notice the NVH.

  • Systems and methods for intelligent vehicle evaporative emissions diagnostics
    Patent number: 10718282
    Abstract: Methods and systems are provided for cleaning a fuel vapor storage canister positioned in an evaporative emissions control system of a vehicle. In one example, a method comprises sealing a fuel system of the vehicle for descending an altitude change that is predicted in advance, and subsequent to the vehicle descending the altitude change, unsealing the fuel system to passively purge fuel vapors stored in the fuel vapor storage canister to a fuel tank of the vehicle. In this way, bleed through emissions from the fuel vapor storage canister may be reduced, and engine operation may be improved.
