    • A stop and start control apparatus of an internal combustion engine prevents fuel supplied in a specific cylinder at the time of stopping the engine from being discharged in an unburned state. When an ignition switch is turned off in a state that the unburned fuel is sealed in the combustion chamber of a specific cylinder during idling stop, the unburned fuel is combusted to prevent the unburned fuel from being discharged. The vibration occurring at that time can be suppressed by rotating the motor generator in the counter direction to the rotation direction of the crankshaft. After the unburned fuel is sealed in the combustion chamber of the specific cylinder, if it is estimated that the unburned fuel is discharged, the exhaust valve corresponding to the specific cylinder is closed at the predetermined timing, or the unburned fuel is combusted, whereby the unburned fuel is prevented from being discharged. Thus, deterioration of emission can be avoided.
    • 内燃机的停止和起动控制装置防止在停止发动机在未燃烧状态下排出的特定气缸中供给的燃料。 当在空转停止期间在未燃燃料被密封在特定气缸的燃烧室中的状态下关闭点火开关时,未燃燃料燃烧以防止未燃燃料的排出。 可以通过使电动发电机沿与曲轴的旋转方向相反的方向旋转来抑制那时发生的振动。 在未燃烧的燃料被密封在特定气缸的燃烧室中之后,如果估计未燃烧的燃料被排出,则与预定时间相关联的特定气缸的排气阀被关闭,或未燃燃料燃烧, 未燃烧的燃料被排出。 因此,可以避免发射的劣化。

    • To a neutral point of a motor is connected a positive electrode of an auxiliary battery and an auxiliary load. Voltage on a power supply line to the auxiliary load, a neutral point voltage, is detected, and disconnection of the auxiliary battery is determined when an increase of ripples in the neutral point voltage is detected. When a voltmeter cannot be used, control of the neutral point voltage is continued by measuring current of the auxiliary battery and performing control such that the current value becomes 0. A resolver is further provided on the motor for detecting the rotor angle with high accuracy. A control circuit generates, in accordance with an output of the resolver, a voltage control signal for each phase current having the same amplitude as the carrier amplitude during startup, and compares the voltage control signal to carrier to obtain a gate signal having the same frequency as the carrier frequency. In switching of the inverter, due to this gate signal, periods in which all phases are on or off are reduced, thereby preventing a large neutral point current.
    • 将电动机的中性点连接到辅助电池的正电极和辅助负载。 检测到辅助负载的电源线上的电压,中性点电压,并且当检测到中性点电压的波动的增加时,确定辅助电池的断开。 当不能使用电压表时,通过测量辅助电池的电流并进行控制使得电流值变为0来继续控制中性点电压。在马达上进一步提供一个高精度检测转子角度的旋转变压器。 控制电路根据分解器的输出,生成与启动时的载波振幅相同幅度的各相电流的电压控制信号,并将电压控制信号与载波进行比较,得到具有相同频率的门信号 作为载波频率。 在逆变器的切换中,由于该门信号,所有相位导通或截止的周期都减少,从而防止大的中性点电流。
