Abstract

PROBLEM TO BE SOLVED: To provide a generator power controller capable of controlling both generated voltage and generated current and efficiently controlling power generation.SOLUTION: Power Pg to be outputted by a generator 7 is computed based on a motor torque command value Tt. A generated voltage command value Vdc<SP>*< / SP>and a generated current command value Idc<SP>*< / SP>for outputting this power Pg are computed. The load on an inverter 9 is varied by varying a PWM pulse width. Thus, control is carried out so that the actual generated voltage value Vdc and the actual generated current value Idc follow the generated voltage command value Vdc<SP>*< / SP>and the generated current command value Idc<SP>*< / SP>.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C §119 to Japanese Patent Application Nos. 2004-376551 and 2004-379594. Accordingly, the entire disclosures of Japanese Patent Application Nos. 2004-376551 and 2004-379594 are hereby incorporated by reference. technical field [0003] The present invention generally relates to generating power control systems for controlling electrical generators. More specifically, the present invention relates to a power generation control system that controls power generation of a generator in a 4WD vehicle, wherein the generator is driven by an internal combustion engine for driving primary drive wheels, and the generator is driven by an internal combustion engine for driving secondary drive wheels. The generator of the wheel drives the AC electric motor. Background technique [0004] There are known various generating power control systems in which, after calculating a voltage comman...
