Abstract

The end customer acceptance of safety systems depends only very indirectly on the actual advantages of the system: accidents occur very rarely, and the actual benefits in such situations can only be judged subjectively with difficulty. The usefulness of the collision warning system discussed here can be objectively defined very precisely. An erroneous warning occurs if the system gives a warning in a situation in which the driver could have avoided a collision without support from the system. The end customer experiences the system in normal circumstances through these "erroneous" warnings. The acceptance of the system is determined by the situations in which warnings occur and the chosen actuators through which the warning is given. Warning systems can therefore be categorised as those which attempt to derive their acceptability from the subjective expectations of the driver, and those which attempt to increase acceptability by keeping the number of "erroneous" warnings to a minimum. In this paper, a method is presented in which a system can be assessed and optimally parameterised according to the desired implementation. The explicit aim is to obtain an optimum balance between acceptability and objective system usability, in order to find the correct implementation for the end customer and vehicle.
