    • PROBLEM TO BE SOLVED: To control the start and the stop of an engine in a power saving manner while improving the in-cabin environment with a simple constitution.SOLUTION: The outside air temperature is detected (100). The time TA until the odor or the like corresponding to the outside air temperature is generated, the eco-run enabled time TB extended by the stop of a blower fan, and the time TC for stopping the operation of the blower fan are obtained from the eco-run map (102). The blower fan is stopped at the time TC during the eco-run (124). When the eco-run enabled time TB is elapsed, the blower fan is operated, the engine start is requested, and the refrigerant circulation by the compressor is started (126). Thus, when the engine is stopped in an eco-run mode, the comfortability of the in-cabin environment is enhanced by operating the blow fan by the predetermined time, and the eco-run enabled time is prolonged to save the power.
    • 要解决的问题:以简单的构造改善机舱内环境,以节电的方式控制发动机的起动和停止。

      解决方法:检测外部空气温度(100)。 产生与外部空气温度对应的气味等的时间TA,通过鼓风机的停止而延长的生态运行允许时间TB和用于停止鼓风机风扇的运转的时间TC从 生态图(102)。 在生态运行期间,鼓风机在时间TC停止(124)。 当经过生态运行启用时间TB时,鼓风机工作,要求发动机启动,并且开始压缩机的制冷剂循环(126)。 因此,当发动机以生态运行模式停止时,通过在预定时间内操作吹风扇来增强车内环境的舒适性,并且延长生态运行允许时间以节省功率。 版权所有(C)2013,JPO&INPIT
