    • A more compact and light-weight drive unit is required for an electric vehicle in order to improve its mileage per charge, acceleration performance and overall efficiency. A control apparatus which generates drive signals to drive power devices in the power converter includes: a current reference generator calculates from a torque reference value a d-axis exciting current reference value on the basis of which the ac motor generates a magnetic flux, and a q-axis torque current reference value, the d-axis and the q-axis being orthogonal to each other; a current control circuit generates ac voltage reference values Vu*, Vv* and Vw* from the d-axis exciting current reference value and the q-axis torque current reference value; and a drive signal generator generates drive signals to drive power devices from the ac voltage reference values. Both the current reference generator and the current control circuit are processed digitally by the same arithmetic unit.

    • A control apparatus of an electric motor vehicle includes a device for operating an initial magnetic pole location based on three phase magnetic pole location signal pulses of a permanent magnet electric motor upon starting the electric motor vehicle, a device for operating a magnetic pole phase of the permanent magnet electric motor on the basis of the initial magnetic pole location, a rotation pulse of the permanent magnet electric motor, and a correction value which are operated with the rise and fall of the three phase magnetic pole location signal pulse after the starting, a device for determining a current to be supplied into the permanent magnet electric motor based on the magnetic pole phase and a torque reference value, and a device for correcting the magnetic pole phase when a predetermined one of the three phase magnetic pole location signal pulses rises or falls. In such an apparatus, as the magnetic pole phase is revised on the basis of the magnetic pole location signal of any one phase among the three phase magnetic pole location signals, the revising frequency of the magnetic pole phase becomes low and the microcomputer processing burden when the magnetic pole phase correction device operates in a high-speed rotation can be reduced.
