Vehicle barrier system
First Claim
1. A method for a vehicle barrier system, the method comprising:
- receiving, by a control system, data from a sensor system indicating the presence of a vehicle at a gateway, wherein the control system is in communication with the sensor system, a first gate system, and a second gate system that is subsequent to the first gate system;
in response to receiving the sensor data indicating the presence of the vehicle, determining, by the control system, whether the second gate system is closed;
in response to determining, by the control system, that the second gate system is closed;
opening, by the control system, the first gate system to allow the vehicle to pass the first gate system; and
attempting, by the control system, to close the first gate system behind the vehicle after the vehicle passes the first gate system;
in response to successfully closing the first gate system behind the vehicle, opening, by the control system, the second gate system to allow the vehicle to proceed through the gateway; and
in response to unsuccessfully closing the first gate system behind the vehicle, generating an alarm by the control system.

Abstract
A vehicle barrier system and method that prevents “tailgating”. The system may include a control system in communication with a sensor system for detecting a vehicle seeking passage through a gateway, as well as a first and second gate system. The control system receives data from the sensor system indicating the presence of the vehicle and, in response, determines whether the second gate system is closed. When the second gate is determined to be closed, the control system opens the first gate system to allow the vehicle to pass the first gate system and attempts to close the first gate system behind the vehicle after the vehicle passes the first gate system. In response to successfully closing the first gate system behind the vehicle, the second gate system is opened to allow the vehicle to proceed through the gateway. Otherwise, an alarm is sounded.

16. A tangible, non-transitory computer-readable medium storing instructions that, when executed by a control system in communication with a sensor system, a first gate system, and a second gate system that is subsequent to the first gate system, cause the control system to:
-
receive data from the sensor system indicating the presence of a vehicle at a gateway; in response to receiving the sensor data indicating the presence of the vehicle, determine whether the second gate system is closed; in response to determining that the second gate system is closed; open the first gate system to allow the vehicle to pass the first gate system; and attempt to close the first gate system behind the vehicle after the vehicle passes the first gate system; in response to successfully closing the first gate system behind the vehicle, opening the second gate system to allow the vehicle to proceed through the gateway; and in response to unsuccessfully closing the first gate system behind the vehicle, generating an alarm. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
