Abstract:
The disclosure relates to a method including the steps of: acquiring a time sequence of sets of vehicle parameter values; determining, for each set of acquired vehicle parameter values, based the set of acquired vehicle parameter values, a measure indicative of an observed strain in a steering rod, between a steering actuator and a wheel; determining, for each set of acquired vehicle parameter values, a measure indicative of a predicted strain in the rod, between the steering actuator and the wheel; and determining the functional status of the steering system based on a relation between the measures indicative of the observed strain in the rod and the measures indicative of the predicted strain in the rod.
