METHOD FOR ESTIMATING AN ACCIDENT RISK OF AN AUTONOMOUS VEHICLE
The present invention relates to a method for estimating an accident risk of an autonomous driving unit. The method produces helpful results with less autonomous driving cycles. An autonomous-driving quantity, quantifying an autonomous-driving quality of the driving of the driving unit, is determined from driving values that have been determined from monitoring at least one driving parameter of the driving unit during autonomous driving. The autonomous-driving quantity is associated with a plurality of manual-driving quantities that have been determined from the same driving parameter during manual driving periods of different driving units. An autonomous-driving accident rate value is determined from accident rate values associated with those manual-driving quantities.
MEASURING DRIVING MODEL COVERAGE BY MICROSCOPE DRIVING MODEL KNOWLEDGE
A computer-implemented method is provided for redundancy reduction for driving test scenarios. The method includes receiving an original test set of driving scenarios and a driving model which simulates a vehicle behavior under a driving scenario inputted to the driving model. The method includes, for each driving scenario of the original test set, obtaining vehicle dynamics timeseries data as an output of the driving model. The method includes determining similar driving scenarios by comparing driving model outputs. The method additionally includes creating a new test set of driving scenarios by discarding duplicated ones of the similar driving scenarios from the original test set.
METHOD AND DEVICE FOR MONITORING OPERATIONS OF AN AUTOMATED DRIVING SYSTEM OF A VEHICLE
The present disclosure describes a method for monitoring operations of an automated driving system (ADS) of a vehicle. For each monitored operation the method includes: determining a geographical position of the vehicle; determining an intended path of the vehicle; and determining one or more intended parameters associated with performing a driving manoeuvre of said vehicle from the determined geographical position along the intended path.
