<p><P>PROBLEM TO BE SOLVED: To safely and surely restart an engine in idling stop so as to cause intermittence of sound and reset of a voice output device as little as possible without increasing capacity of a battery and a boosting means for taking the maximum sound volume of the voice output device into account in this kind of idling stop vehicles in which power sources of an important load for vehicle travel and the voice output device are composed in two system of the battery and the boosting means. <P>SOLUTION: In restart of the engine 3 from idling stop state under control of an SVC control part 8 by boosting voltage of a lead battery 2 power source at a boosting electric power supply part 12b and supplying electricity to the important load for vehicle travel such as the SVC control part 8 and the voice output device 21 when prescribed conditions in an idling stop state are satisfied, output sound volume of the volume output device 21 is limited to sound volume with which electricity supply quantity from the lead battery 2 to the boosting electricity supply part 12b does not exceed set capacity by a sound volume control means, and the engine in idling stop is restarted so as to cause intermittence of sound and reset of the voice output device 21 as little as possible. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
