Embodiment Construction

[0025] The embodiments of the invention with further developments described hereinafter are to be considered as examples only and in no way limit the scope of protection offered by the patent claims. The device is suitable for all types of vehicle combinations that include at least one trailer, but is especially suitable for heavy vehicles, such as trucks towing two or more trailers, because vehicle combinations with more trailers Trailer vehicle combinations are more prone to instability.

[0026] figure 1 A schematic vehicle combination 2 comprising a tractor 3 and two trailers 4, 5 is shown. The tractor is a conventional truck or tractor suitable for commercial highway use. The trailer may be a hitch trailer with front and rear axles. The trailer can also be a semi-trailer with only a rear axle combined with a dolly. In the vehicle combination, different combinations of these trailers or semi-trailers pulled by trucks or tractors can be included. The yaw rate of each v...

Abstract

An arrangement for improving stability of a vehicle combination comprising a towing vehicle and at least one towed vehicle, where the at least one towed vehicle comprises at least one actively steered axle and / or individual brake on at least one axle, where the towing vehicle and the at least one towed vehicle each comprises a yaw rate determining means for determining the yaw rate of the vehicle and the at least one towed vehicle, where the arrangement further comprises a vehicle combination model adapted for determining a desired delay value between the yaw rate of the towing vehicle and the yaw rate of the at least one towed vehicle, where the arrangement is adapted to stabilise the at least one towed vehicle by using the determined yaw rate of the towing vehicle and the desired delay value for the at least one towed vehicle to establish a desired yaw rate for the at least one towed vehicle, and to control the steered axle and / or the individual brake of the at least one towed vehicle such that the determined yaw rate of the at least one towed vehicle corresponds to the desired yaw rate of the at least one towed vehicle. The yaw rate may be estimated or measured. The advantage of the invention is that the stability of a vehicle combination can be improved, which in turn improves the road safety.

Description

technical field [0001] The invention relates to a device and a method for stabilizing a vehicle combination comprising a tractor and at least one trailer. The apparatus and method are particularly suitable for vehicle combinations having more than one trailer. Background technique [0002] In order to reduce the number of heavy vehicles on the road, in some countries longer vehicle combinations comprising more than one trailer are proposed for use on regular roads. In addition to reducing the required number of tractors for a given road, energy consumption and exhaust emissions will be reduced compared to conventional vehicle combinations. Typically, the length and weight of vehicle combinations are governed by laws and regulations. In some countries, longer and / or heavier vehicle combinations are already permitted under restricted conditions. These vehicles may include several trailers and may extend 50 meters or more. They are often used in remote areas and for specifi...
