Problems solved by technology

This has the disadvantage that during rocking, until the clutch is disengaged, the moment of inertia of the engine will brake the backward roll of the vehicle, thus reducing the effectiveness of the rocking function and, in the worst case, preventing the vehicle from successfully leaving

Embodiment Construction

[0018] As mentioned above, it is difficult for a driver with an automatic clutch to achieve as precise a rocking function as desired, since he / she cannot directly influence this process with the clutch pedal.

[0019] The invention solves this problem by using a method in which, unlike the prior art, despite the absence of a clutch pedal, the driver can influence the opening / closing of the clutch in a desired manner.

[0020] figure 1 An example of a power train in a vehicle 100 according to a first embodiment example of the present invention is shown. figure 1 The vehicle 100 shown schematically in Fig. 1 has only one axle with powered wheels 113, 114, but the invention is also applicable to vehicles in which more than one axle is provided with powered wheels. The power train comprises an internal combustion engine 101 connected to a gearbox 103 via a clutch 106 in a conventional manner.

[0021] The vehicle also includes drive shafts 104, 105 connected to powered wheels 11...

Abstract

The present invention relates to a method for control of an automatically controlled clutch when setting a vehicle (100) in motion on a running surface, which vehicle (100) comprises a combustion engine for generating driving force intended for transmission to at least one powered wheel, and a throttle control for demanding driving force from said engine, the magnitude of the driving force demanded from the engine being controlled by a driver of the vehicle by means of said throttle control. The method comprises the step, when a first criterion for a representation of the grip of said powered wheels on said running surface is fulfilled, of - opening said automatically controlled clutch if the driver uses said throttle control to reduce the demand for driving force from said engine.

Description

technical field [0001] The present invention relates to a system for moving a vehicle, and in particular a system for doing so over adverse running surface conditions. In particular, the invention relates to a method as stated in the preamble of claim 1 . The invention also relates to a system as claimed in claim 12 and a vehicle as claimed in claim 14 . technical background [0002] It is well known that vehicles often become stuck when attempting to exit from a standstill in adverse driving surface conditions, and this is especially true for heavy vehicles. Such unfavorable driving surface conditions take the form, for example, of snow or other soft driving surfaces such as sand, mud or the like. [0003] When a vehicle must exit under such conditions, it is usually in a situation where one or more powered wheels become stuck in a pocket or pothole, where the engine torque applied to get the vehicle moving again ( driving force) can cause the power wheel to slip before ...
