Abstract: Systems and methods in accordance with embodiments of the invention continuously collect information from vehicle devices via a vehicle data bus, store information in a database, and retrieve information from the database in response to requests from remote devices. One embodiment includes a vehicle position determining device, a wireless communications device, and a controller apart from at least one operable vehicle device, connected to the vehicle data bus so that the vehicle data bus extends from said controller to at least one operable vehicle device. Additionally, the controller is configured to query at least one vehicle device via the vehicle data bus and store information provided by at least one vehicle device in a database, receive requests for information from a remote device via the wireless communications device, query the database for the requested information, and send the requested information to the remote device via the wireless communications device.

Abstract: Systems and methods for determining vehicle ignition state using a device added to the vehicle after the manufacture of the vehicle without a direct connection to the vehicle ignition line are disclosed. In a number of embodiments, a system includes a processor, a motion detector configured to detect vehicle motion and to enable the processor to obtain motion data, a Global Positioning System (GPS) receiver configured to determine location and to enable the processor to obtain at least speed data, and a radio transceiver configured to communicate with the processor. Additionally, the processor is configured to estimate the ignition state of a vehicle using at least the motion data and the speed data.
