Advanced threat warning for autonomous vehicles
First Claim
1. A method for generating risk indicators, the method comprising:
- determining a vehicle route of a vehicle using vehicle route data including a current vehicle location, a current vehicle destination, and historical vehicle route data;
determining external object routes of external objects using external object route data including current external object locations, current external object destinations, and historical external object route data;
comparing the vehicle route data to the external object route data to determine external object routes that satisfy a proximity criterion, the external object routes that satisfy the proximity criterion being within a predefined proximity of the vehicle route during a predefined time period that is determined using past time periods associated with the vehicle;
generating risk data for the vehicle based on a vehicle state of the vehicle and external object states of the external objects corresponding to the external object routes that satisfy the proximity criterion, the risk data including any of proximity information, severity information, and probability information associated with an adverse event; and
in response to determining that the risk data satisfies a risk criterion, generating at least one risk indicator including a risk type.

Abstract
Methods, apparatuses, systems, and non-transitory computer readable storage media for generating risk indicators are described. The disclosed technology includes determining a vehicle route of a vehicle and external object routes of external objects. The vehicle route is determined using vehicle route data including a vehicle location and a vehicle destination. The external object routes are determined using external object route data including external object locations and external object destinations. Based on a comparison of the vehicle route data and the external object route data, external object routes that satisfy a proximity criterion are determined. Risk data for the vehicle is generated based on a vehicle state of the vehicle and external object states of the external objects corresponding to the external object routes that satisfy the proximity criterion. In response to determining that the risk data satisfies a risk criterion, at least one risk indicator is generated.
