1. A computer system for determining fault for a vehicle crash, the system comprising one or more processors or transceivers of a server configured to:

  • receive, at the server via a communication network, an indication of the vehicle crash involving a vehicle having one or more autonomous vehicle technologies, the indication being transmitted from an on-board computer or mobile device via wireless communication or data transmission;

    receive, at the server via the communication network, a vehicle data log including (a) vehicle-mounted sensor data generated by one or more sensors of the vehicle, and (b) autonomous feature data regarding use, configuration, or settings of one or more autonomous features before and during the vehicle crash, the autonomous feature data including a plurality of control signals generated by the one or more autonomous vehicle technologies to control the vehicle, and the (a) vehicle-mounted sensor data, and (b) autonomous feature data being transmitted from the on-board computer or mobile device via wireless communication or data transmission;

    analyze, by the server, entries in the vehicle data log regarding the (a) vehicle-mounted sensor data, and (b) autonomous feature data regarding the use, configuration, or settings of the one or more autonomous features before and during the vehicle crash to determine an operating control status of the vehicle at the time of the vehicle crash;

    determine, by the server, whether or not the vehicle crash was an unavoidable accident that was the fault of a third party based upon the determined operating control status, wherein the third party includes a pedestrian, an operator of another vehicle, or another autonomous vehicle; and

    when the vehicle was operating in an autonomous mode before and during the vehicle crash, and the vehicle crash was not the fault of any third party;

    evaluate, by the server, the plurality of control signals indicated by the entries of the vehicle data log to identify control actions attempted by the one or more autonomous vehicle technologies;

    determine, by the server and based upon the identified control actions, fault contributions of each of the following as a cause of the vehicle crash;

    (i) the one or more autonomous features failed to generate control signals to control the vehicle to avoid the vehicle crash and (ii) one or more hardware components of the vehicle failed to implement the control signals generated by the one or more autonomous features;

    determine and assign, by the server, a percentage of fault for the vehicle crash to the one or more autonomous features that were in control of the vehicle at the time of the vehicle crash based upon the determined fault contributions;

    perform, by the server, one or more of the following actions based upon the assigned percentage of fault;

    adjust an insurance policy associated with the vehicle, determine a coverage level associated with the insurance policy, present the determination to a reviewer to verify the assigned percentage of fault, or present the determination to a customer for review of the assigned percentage of fault; and

    cause, by communication from the server to a user computing device, an indication of the one or more actions performed to be presented to a user associated with the user computing device via a display of the user computing device.
