dc.description.abstractThe recent trend in connection with heavy trucks is the aim of introducing long heavy vehicle (LHV) combinations which means for example a truck with two trailers. Therefore the powertrain and steering opportunities of the road trains have to be further developed. This can be done with a propelled and steered dolly unit between any two trailers. Thus, they are able to increase the maneuverability of the road train a lot. In this report a complete new concept of dolly is shown. The model has four wheels, but it is track steered, which gives the opportunity to rotate the dolly on one position. On the top is a turn table, which allows the vehicle to go in a small outer laterally offset to the previous vehicles in smaller curves. The physical model is constructed in the scale 1:14 and consists of one truck, two trailers and one of these new kind of dollies. The scaled model is built for the scaled test track of the intelligent vehicles and robots (IVRL) laboratory at Chalmers. Here are the projects for research about autonomous car driving, development, test and validation of active safety systems for cars and trucks in particular. For validating new functions it is cheaper to try it at first in the scaled size, than in the real size. The scaled test track is intended as a tool for seamless transition between computer simulations and full scale proving ground testing. In the end the dolly proves as a useful tool and it confirms the required tasks of the beginning of this Master's thesis project. After a further development of the software to a closed loop system, it should be possible to test some more advanced algorithm.
