Power window system for vehicle

摘要

A power window system includes an occupant existence determination unit and a power supply unit. The occupant existence determination unit determines whether an occupant is in the compartment or outside the passenger compartment, by receiving a signal from a portable device held by the occupant. The power supply unit supplies a power to a window driving unit when the occupant existence determination unit determines that the occupant is in the compartment and when the vehicle ignition key is in an OFF state.
