Power management systems for automotive video event recorders
First Claim
1. A power management system of a vehicle, the system comprising:
- a DC electrical power source;
a video event recorder including a camera unit, a cable, 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 in-use detector is configured to determine whether the vehicle is in use and subsequently activate the switch responsive to vehicle ignition,wherein the switch is configured to provide, subsequent to activation of the switch, power to the video event recorder through the power input,wherein the switch is further configured to, subsequent to deactivation of the switch, leave the video event recorder unpowered, andwherein the cable is arranged to supply power to the video event recorder.

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.
