摘要： A system for control of one or more gearshift points, including at least one control unit for controlling a gearbox in a motor vehicle. The engine is connected to, in order to drive, the gearbox, wherein the speed of the engine is controlled by an accelerator pedal which is connected to the engine and gearbox and can assume a plurality of positions. A shift point is controlled by the accelerator pedal and represents an engine speed at which the gearbox effects a downshift or upshift. The system operates in a first mode in which the one or more shift points are controlled on the basis of movements of the accelerator pedal, and also applies a limitation upon the change in the one or more shift points per unit time. Also a method, a motor vehicle, a computer program and a computer program product for the system are disclosed.

摘要： 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.

摘要： A module for determining speed set-point values vref for a vehicle's control systems includes an input unit configured for input, e.g. by the vehicle's driver, of a reference speed vset which is the speed desired by the driver for the vehicle. A horizon unit is configured for determining a horizon by means of received position data and map data of an itinerary made up of route segments with at least one characteristic for each segment. A processor unit is configured for calculating vref across the horizon according to rules pertaining to categories in which segments within the horizon are placed, so that vref is within a range bounded by vmin, and vmax, where vmin≦̸vset≦̸vmax. The processor unit is further configured for determining a control signal with control parameters for the vehicle's automatic gear change control unit, based on one or more vehicle-specific values and a calculated speed set-point value vref.

摘要： A method for control of a gearbox (20) installed in a motor vehicle (1), which method effects a downshift of the gearbox (20) from a first gear (G1), for which the acceleration a of said vehicle (1) is negative, to a second gear (G2), for which the acceleration a is positive or substantially equal to nil, which downshift involves at least one intermediate gear step between the first gear (G1) and second gear (G2). An engine speed for changing gear at an intermediate gear step is higher than an engine speed for changing gear at a preceding intermediate gear step. Also a system, a motor vehicle, a computer program and a computer program product for performing the method are disclosed.

摘要： A method for control of a gearbox, installed in a motor vehicle (1): The method effects a downshift of the gearbox (20) from a first gear (G1), for which the acceleration α of the vehicle (1) is negative, to a second gear (G2), for which the acceleration α is positive or substantially equal to nil. The downshift involves at least one intermediate gear step between the first gear (G1) and the second gear (G2), using an engine speed ωG1 in the first gear (G1) as an input parameter when effecting the downshift. Also a system, a motor vehicle, a computer program and a computer program product for performing the method are disclosed.
