Abstract

A credential-based vehicle interlock system for preventing unauthorized driving of a land vehicle even when the vehicle is left parked with its engine running. The subject system interacts, inter alia, with the existing sensors and electronic control module of the vehicle to prevent the transmission from shifting out of the “Park” gear, unless and until the credentials of the driver are validated against a database of credentials for authorized drivers. The system can be optionally configured to initiate and execute a controlled shutdown sequence of a moving land vehicle, upon receiving a wireless remote shutdown command.

Claims

door open”

sensor to said existing electronic control module (ECM), so as to initiate, independent of any action of the driver, a controlled vehicle shutdown and braking sequence to slow down and to bring the land vehicle to a stop.

6. The system of claim 5, wherein said wireless reception system is at least one of the following:

cellular, radio, infrared, laser, Wi-Fi and satellite communication.

7. The system of claim 1, wherein the microcomputer (CPU) is further configured to store an event log of credentials received from said credential input device and of determinations made by the microcomputer (CPU) as to whether a driver is authorized or not authorized to drive said land vehicle.

8. The system of claim 7, further comprising a first means of wireless data transmission fitted to said land vehicle, wherein said first means of wireless data transmission is configured to transmit said event log from said land vehicle to a remote recipient.

9. The system of claim 8, further comprising a video camera configured for capturing video of an area proximal to said credential input device, wherein said captured video is configured to be stored on-board the land vehicle.

10. The system of claim 9, further comprising a second means of wireless data transmission fitted to said land vehicle, wherein said second means of wireless data transmission is configured to transmit said captured video from said land vehicle to a remote recipient.

11. The system of claim 10, wherein the first means of wireless data transmission and the second means of wireless data transmission are the same means.

12. The system of claim 11, wherein said credential input device is at least one of the following:

a keypad, a magnetic card reader, a smart card reader, a radio frequency identification device (RFID) controller, an audio recognition device, a biometric recognition device, and an optical reader.

13. The system of claim 10, wherein said second means of wireless data transmission is at least one of the following:

cellular, radio, infrared, laser, Wi-Fi and satellite communication.

14. The system of claim 8, wherein said first means of wireless data transmission is at least one of the following:
