    摘要： In the power supply control system, an electrically heated catalytic converter (EHC) is connected to an alternator output terminal via a switch SW1, and a battery is connected to the alternator via a switch SW2 in parallel with the EHC. A control unit (ECU) for controlling the operation of the switches SW1 and SW2 is provided. When the engine has started, the ECU turns on the SW1 and turns off the SW2 to supply electric power to the EHC directly from the alternator. After the EHC is heated to the activating temperature and starts its catalytic action, the ECU turns on both the switches SW1 and SW2 to supply electric power to the EHC from the battery to maintain the temperature of the EHC. Since the electric power for raising the temperature of the EHC is supplied in the condition where the battery is disconnected from the alternator, the output voltage can be increased to a value higher than a normal output voltage for charging the battery. Therefore, a relatively large electric power can be supplied to the EHC without imposing an excessive load on the battery.

    摘要翻译： 在电源控制系统中，电加热催化转换器（EHC）经由开关SW1连接到交流发电机输出端子，并且电池经由与EHC并联的开关SW2连接到交流发电机。 提供一种用于控制开关SW1和SW2的操作的控制单元（ECU）。 当发动机起动时，ECU打开SW1并关闭SW2，直接从交流发电机向EHC供电。 在EHC被加热到激活温度并开始其催化作用之后，ECU接通开关SW1和SW2，从电池向EHC提供电力以维持EHC的温度。 由于在电池从交流发电机断开的状态下提供用于提高EHC的温度的电力，所以可以将输出电压提高到高于用于对电池充电的正常输出电压的值。 因此，可以向EHC提供相对较大的电力，而不会对电池施加过大的负载。

    摘要： Water contained in exhaust gas discharged from a fuel cell stack 22 is separated by a gas-liquid separator 48 and is accumulated in a recovery tank 54. The procedure of the invention sets a release amount of water and selects one or multiple positions for water release, based on the driving conditions including the vehicle speed and the acceleration, the turning state, activation or non-activation of skid reduction control, the distance from any object detected by clearance sonars 94a through 94d, a distance from a subsequent vehicle measured by an extremely high frequency radar 92, and the presence of raindrops detected by a raindrop detection sensor, and releases the water accumulated in the recovery tank 54 from water outlets at the selected one or multiple positions among water outlets 58a through 58f at multiple different locations. This arrangement ensures adequate release of the water produced by the fuel cell stack 22 to the atmosphere.

    摘要： An electrically heated catalytic converter (EHC) and a battery are connected to an alternator via a changeover switch. The changeover switch connects either of the EHC and the battery to the alternator. The slip-detecting device detects the rotational speed of the alternator from the frequency of the ripple in the output voltage of the alternator when the EHC is connected to the alternator, i.e., when the battery is isolated from the alternator. When the battery is isolated from the alternator, the output voltage of the alternator is raised, and the amplitude of the ripple becomes large accordingly. Further, since the battery is isolated, the ripples in the output voltage are not smoothed by the battery. Therefore, the rotational speed of the alternator is accurately detected. The slip-detecting device detects the slip of the driving belt of the generator based on the rotational speeds of the driver and the alternator.

    摘要： A battery and an electrically heated catalytic converter (EHC) are connected to an alternator in a parallel arrangement via a changeover switch. The changeover switch operates between a first position where it connects the battery to the alternator and a second position where it connects the EHC to the alternator. An electronic control unit (ECU) is provided for controlling the changeover switch and the alternator. When the changeover switch is to be switched between the first and the second position, the ECU first terminates the power generation of the alternator before it actually switches the changeover switch in order to reduce the electric current flowing through the switch. In the switching operation of the changeover switch from the first position to the second position, the ECU determines that sticking of the changeover switch at the first position occurs if the output voltage of the alternator does not become lower than a predetermined value when a predetermined time has lapsed after the switching operation started.
