RISK ESTIMATION IN AUTONOMOUS DRIVING ENVIRONMENTS

The present invention relates to a control system and a method for estimating a risk exposure of an automated driving system (ADS) of a vehicle. The method comprises obtaining an actuation capability of the vehicle, wherein the obtained actuation capability includes an uncertainty estimation for the actuation capability. The method further comprises obtaining a location of free-space areas in the surrounding environment of the vehicle, wherein the obtained location of free-space areas comprises an uncertainty estimation for the estimated location of free-space areas. Furthermore, the method comprise forming a risk map of the surrounding environment of the vehicle based on the obtained actuation capability and the obtained location of free-space areas, wherein the risk map comprises a risk parameter for each of a plurality of area segments comprised in the surrounding environment of the vehicle. The method further comprises determining a total risk value of the ADS based on the risk parameters of a set of area segments intersected by at least one planned path of the ADS.
