Abstract: PROBLEM TO BE SOLVED: To suppress excessive temperature rise of an engine and a motor when abnormality of control signal for controlling drive of a cooling fan used for cooling of the engine, the motor or the like occurs.
SOLUTION: This system determines whether abnormality exists in data input for controlling drive of the cooling fan (step S100, S110). If existence of abnormality is determined, drive level F* of the cooling fan is established to High (Hi) (step S130), and a fan motor is controlled to drive the cooling fan at established drive level F* (step S140). Consequently, the engine and the motor are prevented from reaching high temperature even if abnormality occurs in input data.

解决方案：该系统确定用于控制冷却风扇的驱动的数据输入中是否存在异常（步骤S100，S110）。 如果确定了异常的存在，则将冷却风扇的驱动电平F *设定为高（Hi）（步骤S130），并且控制风扇电动机以以确定的驱动电平F *驱动冷却风扇（步骤S140）。 因此，即使输入数据发生异常，发动机和马达也不会达到高温。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To surely start an internal combustion engine and to suppress resonance generated in the start of the engine. SOLUTION: When a battery temperature Tb does not exceed a threshold value Tb1 or a battery output limit Wout does not exceed a threshold value W1 in the start of the internal combustion engine, that is, when it is possible that motoring of the engine is not normally performed depending on a state of a battery, a fuel injection control is started before an engine speed Ne exceeds a threshold value Nref larger than a resonance speed area (S120 to S140) to start the engine. Therefore, the engine is surely started. On the other hand, when the battery can normally perform the motoring of the engine, the fuel injection control is started after the engine speed Ne exceeds the threshold value Nref larger than the resonance speed area (S120 to S140) to start the engine. Therefore, the resonance generated in the start of the engine is suppressed. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract translation: 要解决的问题：确保启动内燃机并抑制发动机起动时产生的共振。 解决方案：当电池温度Tb不超过阈值Tb1或电池输出限制Wout不超过内燃机启动时的阈值W1时，也就是说，当可能的情况下， 发动机通常根据电池的状态不正常执行，在发动机转速Ne超过大于谐振速度区域的阈值Nref之前开始燃料喷射控制（S120至S140）以启动发动机。 因此，发动机确实启动。 另一方面，当电池正常地进行发动机的电动运转时，在发动机转速Ne超过大于谐振速度区域的阈值Nref（S120〜S140）之后开始燃料喷射控制，以启动发动机。 因此，在发动机起动时产生的共振被抑制。 版权所有（C）2006，JPO＆NCIPI
