1. A system for scoring a trip made by a vehicle, comprising:
- an input interface configured to;
receive trip information generated during the trip, wherein a driver operates the vehicle during the trip; and
receive sensor data associated with the trip; and
a processor configured to;
determine an actual trip factor based at least in part on the trip information, wherein the actual trip factor is based on at least one of fuel economy and a trip safety rating;
determine a simulation characteristic in response to the received sensor data, wherein the simulation characteristic includes a control signal to control vehicle subsystems in response to characteristics of the trip, the control signal being equivalent to an output generated by a driver assistance system in response to the characteristics of the trip;
determine a simulated trip factor based at least in part on the determined simulation characteristic, wherein the simulation characteristic includes at least one of;
simulated fuel economy and a simulated trip safety rating;
determine a trip score based at least in part on a ratio of the actual trip factor to the simulated trip factor;
output the trip score;
determine whether there are any anomalous events on the actual route based on a comparison between the control signal and the trip information; and
activate a driver assistance system in response to the determination that at least one anomalous event has occurred.

Abstract
A system for autonomous driving comparison and evaluation comprises an input interface and a processor. The input interface is configured to receive trip information generated during a driver controlled trip and receive information from an autonomous driving system related to actions that the autonomous driving system would have taken had it been in control during the trip. The processor is configured to compare a trip factor of the driver controlled trip with a simulated trip factor that would have occurred had the autonomous driving system been in control.
