ERRANT VEHICLE COUNTERMEASURES
First Claim
1. A method, comprising:
- determining a vehicle-velocity vector of a vehicle, based on sensor data received from one or more sensors, wherein the vehicle-velocity vector comprises a magnitude component and a direction component;
determining a difference between the vehicle-velocity vector and an authorized-velocity vector, wherein the difference is based on the magnitude component and the direction component of the vehicle-velocity vector;
comparing the difference to a threshold; and
responsive to determining that the vehicle-velocity vector exceeds the threshold, applying a countermeasure to the vehicle.

Abstract
A method, system, and device are presented for providing countermeasures against errant vehicles. A countermeasure controller determines a vehicle-velocity vector based on data from one or more sensors and compares the vehicle-velocity vector to an authorized-velocity vector. The vehicle is determined to be an errant vehicle if the vehicle-velocity vector is not aligned with the authorized-velocity vector. Then, the countermeasure controller may apply countermeasures to the errant vehicle. The countermeasures include electronic countermeasures, informational countermeasures, and physical countermeasures. The countermeasure controller can provide information to other drivers about the errant vehicle via personalized communication or electronic warning signs. The countermeasure controller can be configured to detect entry of vehicles into security areas based on data from one or more sensors. The countermeasure controller may then apply countermeasures to vehicles attempting unauthorized entry into a security area.

12. A countermeasure controller, comprising:
-
a processor; data storage; a sensor interface; and machine language instructions stored in the data storage and executable by the processor to perform functions including; determining that an entering vehicle is attempting to enter a security area based on sensor data received via the sensor interface, requesting authorization data for the entering vehicle, receiving the requested authorization data, determining whether a vehicle is authorized based on the authorization data, and responsive to determining that the vehicle is not authorized, applying a countermeasure to the vehicle. - View Dependent Claims (13, 14, 15, 16)
