Embodiment Construction

[0025] Figure 1A A powertrain in a vehicle 100 according to an embodiment of the present invention is schematically shown. The drivetrain comprises an internal combustion engine 101 connected in conventional manner via an output shaft of the engine (typically via a flywheel 102 ) to an input shaft 109 of a gearbox 103 via a clutch 106 . The clutch may eg take the form of an automatically controlled clutch and is controlled by the vehicle control system via the control unit 110 . The control unit 110 also controls the gearbox 103 . The vehicle 100 also includes propeller shafts 104, 105 connected to the vehicle's traction wheels 113, 114 and driven by an output shaft 107 from the gearbox 103 via a shaft gear 108 (eg a conventional differential). A starter motor 115 is also provided for starting the engine 101 .

[0026] The vehicle 100 also includes various braking systems, such as a conventional primary braking system, which may, for example, include brake discs associated ...

Abstract

The present invention relates to a method for running a vehicle (100), such that said vehicle (100) comprises a combustion engine (101) which can selectively be connected to at least one driveshaft (104, 105) to deliver driving force to said driveshaft (104, 105) for propulsion of said vehicle (100). When said vehicle (100) is in motion, the method comprises : - when said vehicle (100) is approaching a downgrade, determining whether said engine (101) can be disconnected from said at least one driveshaft (104, 105) for at least a first period of time (T1), and - when said engine (101) can be disconnected from said at least one driveshaft (104, 105) for at least said first period of time (T1), disconnecting said engine (101) from said at least one driveshaft (104, 105) for said first period (T1), said engine (101) also being switched off for said first period (T1). The invention relates also to a system and a vehicle.

Description

technical field [0001] The present invention relates to methods and systems for driving a vehicle. In particular, the present invention relates to methods and systems for driving a vehicle under conditions where current propulsion of the vehicle reduces power requirements. The invention also relates to a vehicle and a computer program and computer program product for implementing the method according to the invention. Background technique [0002] Cruise control is now common in motor vehicles such as cars, trucks and buses. The purpose of cruise control is to achieve a consistent predetermined vehicle speed, and cruise control may be of the traditional type aimed at a constant vehicle speed. This can be achieved by adapting the engine torque to avoid deceleration (for example by increasing the engine torque when going uphill). The general purpose of cruise control is to achieve an easy driving of the vehicle and also a greater degree of comfort for its driver. [0003] ...
