Power management systems for automotive video event recorders
First Claim
1. An automotive electrical power management system of a vehicle, the system comprising:
- a DC electrical power source;
an on-board diagnostics system; and
a video event recorder including a camera unit, a cable, an auxiliary female connector, and a power input,wherein the cable includes a terminating connector suitable for coupling with the on-board diagnostics system,wherein the cable is a video event recorder power supply line coupled to the power bus on an individual pin of the power bus, andwherein the auxiliary female connector is arranged in parallel and configured to receive therein an on-board diagnostics system scanner,wherein the DC electrical power source is coupled to the on-board diagnostics system to supply direct current electrical power thereto on a power bus of the on-board diagnostics system,wherein the power input is electrically coupled to the power bus.

Abstract
Video event recorders are coupled to a vehicle power source via an on-board diagnostic system including its power bus, data bus, and scanner port connector. Video event recorders are provided with a power input arranged in conjunction with a standard ODBII type “D” connector. Systems further include an extension cable between the connection and the vehicle event record to accommodate mounting needs associated with each. In advanced versions, both OBD power and data networks are coupled to the vehicle event recorded such that data relating to vehicle diagnostic systems can be captured in a triggered event along with video data. In addition, some versions are provided with special detection mechanism to determine the use state of a vehicle and adjust application of power accordingly. Thus an “in-use” detector is coupled to the vehicle and/or OBD systems to provide feedback which helps to conserve power and regulate the power connections.

15. An automotive electrical power management system comprising:
-
a DC electrical power source; an on-board diagnostics system; a video event recorder including a camera unit and a power input; and a power management module including an in-use detector and a switch, wherein the switch is arranged on a power supply line between the DC electrical power source and the video event recorder, wherein the switch is configured to provide, upon activation of the switch, power to the video event recorder, and wherein the switch is further configured to leave, upon deactivation of the switch, the video event recorder unpowered, wherein the DC electrical power source is coupled to the on-board diagnostics system to supply direct current electrical power thereto on a power bus of the on-board diagnostics system, wherein the power input is electrically coupled to the power bus, wherein the power management module is electrically coupled to the power bus and arranged between the power bus and the camera unit of the video event recorder, wherein the in-use detector is configured to determine that the vehicle is in use and subsequently activate the switch responsive to vehicle ignition. - View Dependent Claims (16)
