  • Apparatus for controlling engine idle and uses thereof
    Patent number: 10760511
    Abstract: An apparatus, method, and system for controlling an idle speed of an internal combustion engine during certain vehicle component operations to minimize unwanted motion and vibration. A transmission neutral engagement, a transmission forward or reverse gear engagement, and a vehicle speed are detected. An engine target idle speed is set to a first speed during the neutral engagement. An engine target idle speed is set to a second idle speed when a vehicle speed is less than a threshold speed and the forward or reverse gear is activated. The vehicle target idle speed is set to a third idle speed when the vehicle speed is greater than a threshold speed while the forward or reverse gear is activated, wherein the first target idle speed, second target idle speed and third target idle speed are different engine speeds.

  • Apparatus for controlling torque control feedback and uses thereof
    Patent number: 10724459
    Abstract: An apparatus, method, and system for controlling the torque of an internal combustion engine during certain vehicle component operations to minimize unwanted motion and vibration. The method includes detecting at least one of reverse gear engagement or reverse movement of the vehicle; wherein a feedback control of the internal combustion engine is switched from open-loop control to closed-loop control upon detection of at least one of a reverse gear activation or reverse movement of the vehicle.
