It is well known and a common experience among drivers that controllability and stability of a car-trailer combination is affected when an articulated Heavy Goods Vehicle overtakes. In this paper, aerodynamic effects to a car-trailer combination when it is overtaken by an articulated HGV, have been analyzed experimentally using 1/20 scale models in wind tunnel, and a method to suppress this phenomeon has been investigated. The dynamic behavior of a car-trailer combination is simulated by a simple mathematical model. The result shows that car-trailer combination can be stable following the addition of aerodynamic devices to each side of the vehicle. This simulated result is verified by the on-road test.
