Abstract

The invention relates to a method the assessing the controllability of a vehicle by a driver in a risky or problematic situation. In order to carry out assessment of the controllability of a vehicle early, the following steps are provided: a. modelling the drive train and the movement dynamics of the vehicle, b. modelling situation conditions and environmental conditions, c. selecting a risky or problematic situation, d. selecting a driver capability type, e. modelling the driver's reaction as a function of the selected driver capability type. f. simulating the dynamic vehicle behaviour in the longitudinal and transverse directions of a planned trajectory on the basis of the drive train model and movement dynamics model for the predefined situation and environmental conditions when the selected risky or problematic situation occurs, g. calculating the maximum lateral and longitudinal deviation from the planned trajectory between the occurrence of the risky or problematic situation and the regaining of complete control by the driver, h. evaluating the controllability of the vehicle by the driver in the risky or problematic situation on the basis of the maximum lateral and/or longitu…
