摘要： A motor current is estimated based on a target motor speed, an actual motor speed, and an engine speed. When the estimated motor current exceeds a predetermined value equivalent to a heat limiting current value, a variation (motor speed F/B amount) of the target motor speed outputted to an EDU (31) from an ECU (30) is restricted so that the motor current was restricted and heat generation in motor (26) is restricted. In consideration of a deterioration of responsivity of the variable valve timing control due to restriction of the motor current during execution of motor current restriction processing, an existence of the abnormalities of variable valve timing controller (18) is determined based on a deviation of the target camshaft phase and the actual camshaft phase.

摘要： An ECU (30) outputs a signal indicative of a target motor speed calculated based on a deviation between a target camshaft phase and an actual camshaft phase to an EDU (31). The EDU (31) performs a feedback control of the output current (motor current) of the EDU (31) so that the deviation is decreased, whereby an actual camshaft phase is feedbacked to a target camshaft phase. When the supply voltage of EDU (31) is less than the operation limit voltage established higher than minimum operation assurance voltage, the variation of the target motor speed is restricted. Thereby, the output current of EDU (31) is restricted, and further, when the supply voltage is less than minimum operation assurance voltage, the output current of EDU (31) is intercepted.
摘要翻译： ECU（30）将表示基于目标凸轮轴相位与实际凸轮轴相位之间的偏差计算出的目标电动机速度的信号输出到EDU（31）。 EDU（31）对EDU（31）的输出电流（电动机电流）进行反馈控制，使得偏差减小，由此将实际的凸轮轴相位反馈到目标凸轮轴相位。当EDU（31）的电源电压小于建立高于最小操作保证电压的操作限制电压时，目标电机速度的变化受到限制。因此，EDU（31）的输出电流受到限制，此外，当电源电压小于最小运行保证电压时，EDU（31）的输出电流被截断。
