Document Type and Number:

Japanese Patent JP4386451

Kind Code:

B2

Abstract:

The present invention relates to a controller and driving apparatus for an electric vehicle, which enables a motor (6) to steadily output torque even when there is an increase in the rotation speed of an internal combustion engine (3) that drives a generator (4). A motor control unit (20) includes a voltage/current command generator F10. The voltage/current command generator F10 includes a base command determination unit (F10A), which determines a base command value for the output voltage of the generator (4) and base command values for d- and q-axis currents that drive an AC motor (6), and power generation operating point change means, which changes the command values that are output from the base command determination unit (F10A). When an operating point of the generator (4) approaches an unstable region where the generator (4) unsteadily operates, the power generation operating point change means (F10B) changes the generator's operating point to position it within a stable region.
