From the background information supplied by the inventors, news correspondents obtained the following quote: “Vehicle or automobile insurance exists to provide financial protection against physical damage and/or bodily injury resulting from traffic accidents and against liability that could arise therefrom. Typically, a customer purchases a vehicle insurance policy for a policy rate having a specified term. In exchange for payments from the insured customer, the insurer pays for damages to the insured which are caused by covered perils, acts, or events as specified by the language of the insurance policy. The payments from the insured are generally referred to as “premiums,” and typically are paid on behalf of the insured over time at periodic intervals. An insurance policy may remain “in-force” while premium payments are made during the term or length of coverage of the policy as indicated in the policy. An insurance policy may “lapse” (or have a status or state of “lapsed”), for example, when premium payments are not being paid or if the insured or the insurer cancels the policy.
“Premiums may be typically determined based upon a selected level of insurance coverage, location of vehicle operation, vehicle model, and characteristics or demographics of the vehicle operator. The characteristics of a vehicle operator that affect premiums may include age, years operating vehicles of the same class, prior incidents involving vehicle operation, and losses reported by the vehicle operator to the insurer or a previous insurer. Past and current premium determination methods do not, however, account for use of autonomous vehicle operating features. The present embodiments may, inter alia, alleviate this and/or other drawbacks associated with conventional techniques.”
Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’ summary information for this patent: “The present embodiments may be related to autonomous or semi-autonomous vehicle functionality, including driverless operation, accident avoidance, or collision warning systems. These autonomous vehicle operation features may either assist the vehicle operator to more safely or efficiently operate a vehicle or may take full control of vehicle operation under some or all circumstances. The present embodiments may also facilitate risk assessment and premium determination for vehicle insurance policies covering vehicles with autonomous operation features.
“In accordance with the described embodiments, the disclosure herein generally addresses systems and methods for monitoring the use of a vehicle having one or more autonomous (and/or semi-autonomous) operation features and determining fault following the occurrence of an accident involving the vehicle. An on-board computer or mobile device may monitor and record vehicle operating data, including sensor data and data from the one or more autonomous operation features. A server may receive the operating data and may process this data to determine the cause of and fault for the accident. These fault determination may then be used (wholly or partially) to determine an adjustment to an insurance policy associated with the vehicle and/or an adjustment to risk levels associated with the autonomous operation features.
“In one aspect, a computer-implemented method for determining fault relating to a collision or other loss may be provided. The computer-implemented method may include receiving an indication of an accident involving a vehicle having one or more autonomous (and/or semi-autonomous) operation features for controlling the vehicle, receiving operating data regarding operation of the vehicle during a time period including the time of the accident, receiving information regarding use levels of the one or more autonomous operation features during the time period including the time of the accident, and/or determining an allocation of fault for the accident based upon, at least in part (i.e., wholly or partially), the received operating data and the use levels of the one or more autonomous operation features. The indication of the accident may be generated based upon, at least in part (i.e., wholly or partially), the received operating data. The operating data may include information from one or more sensors disposed within the vehicle and/or information regarding the operation of the one or more autonomous operation features. Additionally, the autonomous operation features may include one or more autonomous communication features, in which case the operating data may include communication data from external sources. The method may include additional, fewer, or alternate actions, including those discussed elsewhere herein.
“In another aspect, a computer system for determining fault relating to a collision or other loss may be provided. The computer system may include one or more processors, one or more communication modules adapted to communicate data, and a non-transitory program memory coupled to the one or more processors and storing executable instructions. The executable instruction may, when executed by the one or more processors, cause the computer system to receive an indication of an accident involving a vehicle having one or more autonomous (and/or semi-autonomous) operation features for controlling the vehicle, receive operating data regarding operation of the vehicle during a time period including the time of the accident, receive information regarding use levels of the one or more autonomous operation features during the time period including the time of the accident, and/or determine an allocation of fault for the accident based upon the received operating data and the use levels of the one or more autonomous operation features. The indication of the accident may be generated based upon the received operating data. The operating data may include information from one or more sensors disposed within the vehicle and/or information regarding the operation of the one or more autonomous operation features. Additionally, the autonomous operation features may include one or more autonomous communication features, in which case the operating data may include communication data from external sources. The system may include additional, fewer, or alternate actions, including those discussed elsewhere herein.
“In yet another aspect, a tangible, non-transitory computer-readable medium storing instructions for determining fault relating to a collision or other loss may be provided. The instructions may, when executed by at least one processor of a computer system, cause the computer system to receive an indication of an accident involving a vehicle having one or more autonomous (and/or semi-autonomous) operation features for controlling the vehicle, receive operating data regarding operation of the vehicle during a time period including the time of the accident, receive information regarding use levels of the one or more autonomous operation features during the time period including the time of the accident, and/or determine an allocation of fault for the accident based upon the received operating data and the use levels of the one or more autonomous operation features. The indication of the accident may be generated based upon the received operating data. The operating data may include information from one or more sensors disposed within the vehicle and/or information regarding the operation of the one or more autonomous operation features. Additionally, the autonomous operation features may include one or more autonomous communication features, in which case the operating data may include communication data from external sources. The instructions of the computer-readable medium may include additional, fewer, or alternate actions, including those discussed elsewhere herein.”
