A commercial vehicle with good active safety is singled out for distinction, in that it remains stable during critical situations and that it can be controlled and brought to a safe standstill by the driver. This paper illustrates which parameters substantially influence the behaviour of a 15-t straight truck and a 32-t tractor/semi-trailer unit carrying out the ISO-Test-Procedure 'Braking in a Turn', which is well suited to assess the active safety of vehicles. The results of the investigations indicate that the vehicle reaction is highly dependent on the initial lateral acceleration, the axle elastokinematics, the tire characteristics and the longitudinal deceleration. The most essential factor influencing the directional stability while braking in a turn is the braking force distribution of the vehicle and the braking force distribution between tractor and trailer. Disharmonizations of the braking force distribution may lead to situations which are not controllable anymore by the driver. When equipping the vehicle with an anti-look system, the driving safety can be essentially improved.
