US Patent 7759818 Intermittent driving system

An intermittent driving system includes a control target circuit to determine and notify a switching timing of ON/OFF of a power supply, and a control circuit to send a power supply ON signal for turning on the power supply or a power supply OFF signal for turning off the power supply of the control target circuit based on the switching timing decided by the control target circuit. The control target circuit is an in-vehicle monitoring circuit including a monitoring camera to monitor a in-vehicle and the control target circuit determines the switching timing based on a monitoring result of the monitoring camera.
