Abstract
Cautious driving and cautious driving speed determination for an autonomous vehicle is responsive to receiving a non-yield backup prediction for the vehicle regarding a traffic participant in a region of interest in a road network surrounding the vehicle, the non-yield backup prediction including a non-yield probability value for the traffic participant not yielding to the vehicle. Driving information, including speed, for other traffic participants within the region of interest is obtained from a sensor system, and an average speed of the other traffic participants is determined. A driving system determines a cautious driving speed for the vehicle by calculating a reverse probability value, which is a reverse percentage of the non-yield probability value relative to a maximum value for it, and multiplying the average speed of the other traffic participants by the reverse probability value. The driving system controls the vehicle to reduce its speed to the cautious driving speed.
