    Abstract: A power supply control apparatus for controlling an electric generator of a vehicle limits the rate of change of a power supply voltage to a predetermined variation rate range, when the change is caused by operations to control the charge condition of the vehicle battery, and controls the generated power to match the drive torque applied by the engine to the generator. When the electrical load demand changes, the generated power is controlled to limit a resultant momentary change in the power supply voltage caused by an engine response delay, while minimizing a resultant momentary amount of engine speed variation.

    Abstract: A required-generate-current (RGC) is calculated according to conditions of the electric loads and a charging state of the battery. The required-alternator-drive-torque (RADT) is estimated according to the required-generate-current (RGC). A required engine torque is calculated by adding the required-alternator-drive-torque (RADT) and the required-vehicle-drive-torque (RVDT) together. The engine torque which is realized at next calculating timing is estimated in consideration of a response delay of the engine. The differential torque between the estimated engine torque and the required-vehicle-drive-torque (RVDT) is calculated as the permission torque. The command current corresponding to the permission torque is calculated. The control current of the alternator is controlled in such a manner as to generate current corresponding to the command current at the next calculating timing.

    Abstract: An engine controller controls an engine, which drives a generator, an auxiliary device, and a vehicle. The generator generates electricity, and supplying the electricity to a battery and a plurality of current consumers. A generator controller controls the generator. An auxiliary device controller controls the auxiliary device. An electric power generation calculation unit calculates one of a requested power generation of the generator and a present power generation of the generator. An engine speed changing unit evaluates tendency of power generation on the basis of the one of the requested power generation and the present power generation. The engine speed changing unit requests increase or decreases in the engine speed when the engine speed changing unit determines the power generation to be inclined toward shortage or excess.
