  • Patent number: 11110930
    Abstract: A control device for an automatic transmission includes a traveling drive source, an automatic transmission, an AT controller, and a traveling drive source controller. The AT controller is configured to execute shifting by changeover of friction elements upon receiving a shift request. The traveling drive source controller is configured to execute torque limit control of the traveling drive source when a request for limiting a torque by an upper limit torque is input from the AT controller. The AT controller has an upper limit torque change processing unit configured to change the upper limit torque from a low gear upper limit torque to a high gear upper limit torque when auto-upshift is executed. The upper limit torque change processing unit is configured to raise the upper limit torque using a prescribed gradient during an inertia phase when the inertia phase is started with the auto-upshift.

  • Patent number: 10711714
    Abstract: The invention relates to a method for operating an internal combustion engine during any driving operation and in particular during a defined testing cycle which determines compliance with regulations. The internal combustion engine has at least one exhaust gas aftertreatment device with an adjustable degree of efficiency (for example by changing the reduction agent) or an exhaust gas recirculation device or alternative variables for changing the raw engine emissions. At least one monitoring window is assigned to the active profile. The aim of the invention is to allow strict exhaust gas regulations to be met in particular during real driving operations while simultaneously allowing a low fuel consumption. This is achieved in that at least one main monitoring window of the driving profile and a sub-monitoring window (F2) with a starting point and an end point are defined within a driving profile or test cycle.

  • Patent number: 9133775
    Abstract: A system for a vehicle includes a misfire indication module, a valve control module, and a fault indication module. The misfire indication module selectively indicates that misfire occurred within a cylinder of an engine. The valve control module controls lifting of a valve of a cylinder of the engine and, in response to the misfire indication module indicating that misfire occurred within the cylinder, transitions lifting of the valve from one of a low lift state and a high lift state to the other one of the low lift state and the high lift state. The fault indication module selectively indicates that a fault is present in a variable valve lift (VVL) mechanism of the cylinder based on whether the misfire indication module indicates that misfire occurred within the cylinder after the transition to the other one of the low lift state and the high lift state.

  • Publication number: 20150149065
    Abstract: A method controls an internal combustion engine that has a drive output shaft connected to an input shaft of a transmission. The internal combustion engine, the transmission and a drive wheel are encompassed by a drivetrain for the drive of a motor vehicle. The method includes determining a rotational acceleration of the input shaft and determining an input torque at the input shaft of the transmission based on a product of the rotational acceleration and a speed reduction ratio-dependent moment of inertia of the drivetrain in a section between the input shaft and the drive wheel. A combustion torque of the internal combustion engine is controlled such that the input torque adheres to a predetermined maximum input torque at the input shaft of the transmission.
