    • When performing PWM control in accordance with an overmodulation mode, an ECU variably sets a switching determination value, which is used for determination of switching control modes between the overmodulation mode and a sinusoidal wave modulation mode, based on a switching state of an inverter at present. Then, the ECU compares the degree of modulation, which is calculated from voltage command values, with the switching determination value so as to determine whether to switch to the sinusoidal wave modulation mode or to maintain the overmodulation mode. In particular, when an influence of a dead time is likely to cause generation of a voltage command that requires switching to the overmodulation mode just after switching to the sinusoidal wave modulation mode, the switching determination value is variably set to prevent the transition from the overmodulation mode to the sinusoidal wave modulation mode. This prevents chattering in which the control modes are frequently switched therebetween.
    • 当根据过调制模式执行PWM控制时,ECU基于目前的逆变器的开关状态可变地设置用于确定过调制模式和正弦波调制模式之间的开关控制模式的开关判定值 。 然后,ECU将根据电压指令值计算的调制度与切换判定值进行比较,以便确定是切换到正弦波调制模式还是维持过调制模式。 特别地,当切换到正弦波调制模式之后,当死区时间的影响可能导致产生需要切换到过调制模式的电压指令时,切换判定值被可变地设置以防止过调制 模式到正弦波调制模式。 这防止其间经常切换控制模式的抖动。
