From the background information supplied by the inventors, news correspondents obtained the following quote: “Vehicles may be equipped with sensors for processing and communication capabilities that allow the vehicle to navigate autonomously without human intervention. Autonomous vehicle navigation is not possible, however, under all circumstances. In some situations, a vehicle may lack the capability to navigate autonomously such as adverse or extreme weather conditions, in the event of the loss of vehicle sensors or a communications link, under disaster conditions, due to vehicle collisions in the area, etc. When a vehicle can no longer navigate autonomously, control of the vehicle may be returned to a human operator. Transfer of control of the vehicle to a human represents a potential danger due to the vehicle’s autonomous nature-a human operator who has been traveling in the vehicle may be inattentive to road conditions and unprepared to make the decisions and exercise the motor control needed to safely operate the vehicle. Human operators will differ in their ability to operator an autonomous vehicle, especially when accepting increased driving responsibilities, and therefore present varying levels of risk in operating autonomous vehicles.”
Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’ summary information for this patent: “This summary is provided to introduce a selection of concepts in a simplified form that are further described in the Detailed Descriptions. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
“Systems and methods are disclosed for assessing driver capability for operating an autonomous vehicle. Human operators of autonomous vehicles may exhibit varying levels of operating proficiencies and may respond differently to changing road conditions or requests from the vehicle to assume more or less control over navigation. A system for assessing driver capability of an autonomous vehicle assesses human operator capabilities in a variety of circumstances to assemble a driving capability profile of the human operator. The autonomous vehicle may rely on the driving capability profile as well as an environmental profile and human operator parameters describing the environment surrounding the vehicle and an alertness level of the human operator, respectively. The vehicle may condition requests to increase or decrease driving responsibilities of the human operator depending on the driving capability profile in combination with the environmental profile and/or the human operator parameters. An insurer may condition an insurance premium cost for a time period based on the driving capability profile in combination with the environmental profile and/or the human operator parameters.
“In one aspect, a method is disclosed for assessing driver capability for operating an autonomous vehicle. The method may include identifying a human operator of the vehicle, the human operator being associated with a driving capability profile, and determining human operator parameters associated with the human operator of the vehicle. The method may also include determining an alertness level of the human operator based on the human operator parameters; signaling, by a notification server of the vehicle, to the human operator with a signal requesting a response from the human operator; and updating the driving capability profile based on the response from the human operator to indicate a level of skill of the human operator at responding to the signal at the determined alertness level.
“In another aspect, a system is provided for assessing capability of a driver of an autonomous vehicle. The system may include a processor configured to determine human operator parameters associated with a human operator of the vehicle; an evaluator configured to evaluate an alertness level of the human operator based on the human operator parameters; a notification server configured to present a signal to the human operator, the signal requesting a response from the human operator, wherein the evaluator is further configured to receive the response from the human operator; and an assessor configured to update a driving capability profile of the human operator to indicate a level of skill of the human operator at responding to the signal at the evaluated alertness level. The assessor may determine the level of skill based at least in part on the response from the human operator.
“In yet another aspect, a method of insuring a vehicle against loss is disclosed. The method may include receiving a driving capability profile of a human operator of a vehicle, receiving human operator parameters associated with the human operator, determining an alertness level of the human operator based on the human operator parameters, and receiving a response from the human operator to a signal, the signal presented by a notification server of the vehicle to the human operator and requesting a response from the human operator. The method may further include updating, based on the response from the human operator to the signal, the driving capability profile to indicate a level of skill of the human operator at responding to the signal at the determined alertness level. The method may also include determining a risk of insuring the vehicle, the risk being based at least in part on the driving capability profile. Still further, the method may include transmitting an insurance offer to the human operator, the insurance offer being based at least in part on the determined risk of insuring the vehicle.”
