摘要： PROBLEM TO BE SOLVED: To more properly start force feed devices including an electric oil pump that feeds an oil for cooling a motor, and to more properly judge the abnormality of the force-feed devices. SOLUTION: Whenever motor temperatures Tm1, Tm2 rise by 10°C from a starting initial temperature Tset, the starting of the oil pump is attempted that feeds the oil of a motor cooling system to an oil cooler (S100-S180). This operation makes it possible to start the oil pump more reliably even in the high viscosity state of the oil that is caused by low outside air temperature to some extent. If the oil pump cannot be started even with a plurality of such attempts, the oil pump is judged to be abnormal when the outside air temperature Tout is equal to or higher than a predetermined temperature Tref, and not judged to be abnormal when the outside air temperature Tout is lower than the predetermined temperature Tref (S190-S220). Thus, the wrong detection of the abnormality of the oil pump can be restrained. COPYRIGHT: (C)2006,JPO&NCIPI

解决方案：当电机温度Tm1，Tm2从启动初始温度Tset上升10℃时，尝试将电机冷却系统的油供给油冷却器的油泵启动（S100-S180）。即使在一定程度的外部空气温度低的油的高粘度状态下，也能够更可靠地启动油泵。即使在多次这样的尝试中油泵也不能启动，当外部空气温度Tout等于或高于预定温度Tref时，油泵被判定为异常，并且当外部空气温度Tout低于预定温度Tref（S190-S220）。因此，可以抑制油泵的异常的错误检测。版权所有（C）2006，JPO＆NCIPI
