Problems solved by technology

If, on the contrary, the articulated coupling is strongly damped, the vehicle becomes understeer and, for example, it becomes difficult to turn the vehicle as required at a curve or a fork in the road, and at the same time it becomes difficult to straighten the vehicle after the turn

Embodiment Construction

[0019] An articulated vehicle 1 with a damping system according to the invention in figure 1 is schematically shown in . In the example shown, the vehicle is in the form of an articulated bus. The vehicle comprises a front vehicle element 2 and a rear vehicle element 3 pivotably connected to said front vehicle element by means of an articulated coupling 20 . The vehicle elements 2 , 3 are pivotable about a vertical pivot axis A relative to each other. In the example shown, the rear vehicle element 3 has at its rear end a set of powered wheels 5A driven by a vehicle engine 6 located in the rear vehicle element 3 . The vehicle engine 6 is connected via a gearbox 8 to the axle 7a of the powered wheels. In the example shown, the powered wheels 5a are steerable, but could alternatively be non-steerable. The front vehicle element 2 has at its front end a front axle 7c with two pivotable wheels 5c. At its rear end, the front vehicle element 2 has an axle 7b representing the cent...

Abstract

Damping system for articulated vehicle and method for regulating such a damping system. In a normal state, when there is no risk situation with regard to mutual outswing between the forward vehicle element (2) and the rear vehicle element (3) of the vehicle, the damping means (30a, 30b) of the damping system are caused to exert a damping force which is pulsated, in order thereby to facilitate mutual straightening up between the forward vehicle element and the rear vehicle element. When it is determined that there is a risk situation with regard to mutual outswing between the forward vehicle element and the rear vehicle element, the damping means are caused to exert a damping force which is non-pulsated and stronger than the damping force in the normal state, in order thereby temporarily to prevent the articulation angle from increasing, after which the damping means are caused to revert to the normal state with pulsated damping force of reduced strength.

Description

technical field [0001] The invention relates to a damping system according to the preamble of claim 1 for counteracting the mutual pivot between a front vehicle element of an articulated vehicle and a rear vehicle element connected to the front vehicle element by an articulated coupling. rotational movement, and a method for adjusting the damping force of such a damping system. The invention also relates to a computer program product comprising computer program code for carrying out the method according to the invention and an electronic control unit. Background technique [0002] In this specification and the claims presented below, articulated vehicle means a vehicle comprising a front vehicle element and a rear vehicle element pivotally connected to each other by an articulated coupling intended to allow the The elements pivot relative to each other about a vertical pivot axis. In this description and the claims presented below, the angle between the front and rear vehi...
