Problems solved by technology

However, the scheme in which the front body is pushed by the rear body results in driving characteristics that are largely different from non-articulated vehicles and articulated vehicles with the front body acting as a tractor
[0005] For example, if the articulation joint can turn too freely, that is, too undamped, there is a possibility that the rear body of the vehicle will throw the center axle, that is, the rear axle of the front body, or the center of the vehicle out and sideways. Risk of rollout, especially in winter conditions and other slippery conditions
Also, if the articulation is too undamped at high speeds, the vehicle may become jerky

Embodiment Construction

[0015] In the description and claims of the present invention, the phrase "front vehicle body" shall be interpreted as meaning a vehicle body having at least one steering axle. Furthermore, "rear body" shall be interpreted as a body having at least one rear axle, wherein said rear body is arranged to be connectable to said front body using articulation means, ie swivel joints.

[0016] Furthermore, in the description and claims, the term "control unit" shall be interpreted as a unit comprising control logic capable of exchanging digital data with other control units.

[0017] As mentioned above, articulated vehicles generally have increased capacity compared to conventional vehicles. figure 1 An example of an articulated vehicle in the form of a bus 10 is disclosed to which the present invention may be advantageously applied. The bus 10 is composed of a front body 11 and a rear body 12, wherein the front body 11 and the rear body 12 are connected together by a hinge mechanism...

Abstract

The present invention relates to an articulation control system for use with an articulated vehicle (10) having a front vehicle body (11) and a rear vehicle body (12), said front and rear vehicle bodies (11, 12) being arranged to be connected together by articulation means (13) comprising first damping means and second damping means for providing relative rotation relative to each other, said system comprising control means for controlling said rotation by controlling said first damping means and said second damping means. The system includes a first control unit (31) for controlling said first damping means, and a second control unit (32), separate from said first control unit (31), for controlling said second damping means. The present invention also relates to a vehicle.

Description

technical field [0001] The present invention relates to an articulation control system for an articulated vehicle for use with an articulated vehicle having a front body and a rear body. The invention also relates to an articulated vehicle comprising said articulation control system. Background technique [0002] Long vehicles have many advantages, for example they have a higher loading capacity than shorter vehicles. However, a disadvantage is that a long body requires a lot of space, for example when cornering. Therefore, long vehicles for urban use are usually constructed as articulated vehicles. Such vehicles are, for example, buses, articulated trucks and trailer trucks. The articulation facilitates the trafficability of the vehicle in urban areas and at the same time has the advantage of a long body, ie a higher passenger capacity or loading (transportation) capacity. [0003] A conventional driveline for an articulated vehicle uses a steered front axle and a drive...
