20100131159 | METHOD OF CONTROLLING A VTG ENGINE - When controlling an engine provided with Variable Turbine Geometry (VTG), the VTG is closed to a maximally acceptable closed position without endangering the VTG when performing an up-shift. The VTG is kept in such a position during the gear shift which, allows for a quick retardation of the engine speed. | 05-27-2010 |
20100145593 | GEARSHIFT CONTROL METHOD - In a method and a system for controlling the Variable Turbine Geometry (VTG) of a combustion engine during up-gear shift, the VTG is opened based on a prediction when exhaust gas pressure is stabilized.

20100198479 | METHOD OF CONTROLLING A VTG ENGINE - When controlling an engine having a Variable Turbine Geometry (VTG) the VTG is closed some predicted time period before an up-gear shift is performed. This is advantageous because when the gear shift begins the engine breaking is already maximized and full engine brake can be obtained during the entire gear shift operation. | 08-05-2010 |

The gearbox also effects a manual gear change in an automatic mode if a mode selector connected to the gearbox is activated. The manual gear change is barred if the mode selector is only activated a first time during a gear change period, which represents a period of time during which an automatic gear change is effected in the automatic mode. A system, a computer program, a computer program product and a motor vehicle, which prevent an unwanted double gear change, are disclosed. | 06-21-2012 |
20120158263 | SYSTEM FOR CONTROL OF A GEARBOX - A system for control of a gearbox, having at least one control unit controlling the gearbox where the gearbox is installed in a motor vehicle having an engine connected to drive the gearbox. The system effects a first upshift from a first gear to a second gear if the acceleration a for the vehicle is greater than nil for the second gear and the current engine speed is within a first engine speed range; and effects a second upshift from the first gear to a third gear if the current engine speed is within a second engine speed range. The first speed range is lower than the second speed range of the engine. A method, a motor vehicle, a computer program and a computer program product for the method are disclosed. | 06-21-2012 |
20120166051 | METHOD FOR DETERMINATION OF GEARSHIFT POINTS - A method for determination of one or more downshift and upshift points for a gearbox in a motor vehicle. The vehicle includes an engine connected to the gearbox, where a downshift point represents a first engine speed at which the gearbox effects a downshift, and an upshift point represents a second engine speed at which the gearbox effects an upshift. One or more downshift and upshift points are determined relative to an engine target speed which is a desired speed for the engine. A system, a motor vehicle, a computer program and a computer program product thereof perform the method. | 06-28-2012 |
20120166054 | DETERMINATION OF ONE OR MORE GEARSHIFT POINTS - A method, a system, a computer program and a computer program product for determining one or more shift points for a gearbox in a motor vehicle which comprises an engine connected to, in order to drive the gearbox. A shift point is defined by an engine speed at which the gearbox effects a downshift or upshift. The method uses one or more shift points determined on the basis of a change in road gradient. | 06-28-2012 |
20120173095 | METHOD FOR DETERMINATION OF NUMBERS OF GEAR STEPS - A method for determining numbers of gear steps N for a gearbox in a motor vehicle. The vehicle has an engine connected to drive the gearbox. The numbers of gear steps N is the number of downshifts or the number of upshifts which the gearbox effects at an upshift point or a downshift point. A downshift point represents a first engine speed at which the gearbox effects a downshift. An upshift point represents a second engine speed at which the gearbox effects an upshift. The numbers of gear steps N are determined on the basis of a predicted acceleration a for the motor vehicle during a time period T. The invention relates also to a system, a motor vehicle, a computer program and a computer program product thereof for performing the method. | 07-05-2012 |
