20130304330 | METHOD AND SYSTEM FOR REGULATING THE LINEAR POSITION OF A FIFTH WHEEL - A method and a system for regulating, while the vehicle is in motion, the linear position of a fifth wheel of a vehicle combination which comprises a tractor unit and a semi-trailer, which linear position of the fifth wheel is regulated automatically on the basis of the vehicle speed. Forward movement of the fifth wheel ordered in response to an increase in the vehicle speed, in order to reduce the distance between the driving cab and the semi-trailer, is effected at a faster rate of movement of the fifth wheel at times when the tractor unit is performing a gear change operation than at times when the tractor unit is not performing a gear change operation. When a rearward movement of the fifth wheel to increase the distance between the driving cab and the semi-trailer has to be effected in response to a decrease in the vehicle speed, braking of the semi-trailer relative to the tractor unit is ordered, in order thereby to facilitate the rearward movement of the fifth wheel. | 11-14-2013 |
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 |
20090235776 | GEAR CHANGE ARRANGEMENT AND A GEARBOX - A control device for controlling engagement of desired gears of a gearbox. The control device includes a holder unit and at least one control rod which has a relating locking arrangement and is arranged for linear movement in the holder unit. The control rod is provided with one or more recesses which each define a predetermined setting position of the control rod relative to the holder unit. The locking arrangement includes a locking device which is movable, substantially perpendicularly to the control rod's longitudinal axis, between a first position in which the locking device engages in one of the recesses in the control rod, and a second position in which the locking device does not engage in any of the recesses in the control rod. A wire spring fastened in a holder arrangement is firmly connected to the holder unit. The locking device is mounted on or forms part of the wire spring and is movable from the first position to the second position against the action of the spring force of the wire spring. A gearbox comprising such a control device is disclosed. | 09-24-2009 |
