<P>PROBLEM TO BE SOLVED: To prevent degradation of merchantability by preventing rapid change of a battery voltage due to idle stop, and recognizing a remarkable operation change of electrical equipment by a driver. <P>SOLUTION: When there is possibility of entering idle stop control, the power generation capacity of an alternator 4 is gradually reduced to a set value by a first power generation stop control part 21 until a vehicle stops, and when an engine is stopped by the vehicle stop, the power generation capacity is controlled to be gradually set to 0 by a second power generation stop control part 22. When restarting the engine from idle stop, the power generation capacity immediately after the engine restart end is set at 0% by a power generation start control part 23, thereafter the power generation capacity is gradually increased from 0%, and the power generation capacity is controlled to be set at 100% after a predetermined time. Thereby, luminance change of illumination and change of the wiping speed of a wiper by the rapid change of battery voltage at the engine stop and restart due to the idle stop are suppressed, and degradation of merchantability can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
