<p>An in-vehicle wireless communications device executes an emergency report operation to transmit an emergency report signal from a wireless communications unit to a wireless communications network. During this emergency report operation, integrated electric currents from an in-vehicle battery to an in-vehicle wireless communications device reach a predetermined value, which generates an interrupt. Even at this time, stopping of an operation power from the in-vehicle battery to the wireless communications unit is suspended until the emergency report operation is normally finished.</p> |
