SYSTEM OF ELECTRONIC FOR VEHICLE TO SIMPLIFY A POWERLINE

摘要

An electronic system having a car with a simplified power line is provided not to stop an electronic unit/system even during short-cut or open of power. An electronic system having a car with a simplified power line includes two power terminals, a power line, a control circuit(130) and a communication unit. The power terminals include a power switch. The power switch has current limit inside and simultaneously supplies or cuts a mutual voltage. The power line supplies power to the power terminal. The control circuit determines whether power is normally supplied to a power terminal. The communication unit transceives a signal to determine a state of a device from a spot away from the control circuit.
