    • A motor controlling device for mounting on a vehicle, which includes a controller capable of controlling a DC brushless motor at high response and high accuracy. The motor controlling device for mounting on the vehicle to drive the DC brushless motor comprises a main control section (120) for calculating a torque command for the motor, and a current control calculation section (140) constituted by a module or a dedicated LSI independent of the main control section (120). The current control calculation section (140) converts the coordinates of a current of the DC brushless motor into a d-axis direction, i.e., a direction of magnetic flux of a motor rotor, and into a q-axis direction orthogonal to the d-axis direction, and feedback-controls a current in the d-axis direction and a current in the q-axis direction separately.

    • In an arrangement having an electric power inverter 2 which applies a voltage to an AC motor 1 and a control unit 4 which calculates a voltage command value applied in PWM signals, detection use voltages Vup, Vvp and Vwp are applied in synchronism with PWM signal generation use carrier waves in the control unit 4 as well as motor currents iv and iv are detected in response to current detection pulses Pd in synchronism therewith. In a magnetic pole position detection unit 12, counter electromotive forces of the synchronous motor 1 are estimated from a relationship between the detection use voltages Vup, Vvp and Vwp and current difference vectors of the motor current to determine a magnetic pole position &thgr; through calculation. The determined magnetic pole position &thgr; is inputted to coordinate conversion units 8 and 11 and a motor speed detection unit 13. Thereby, a motor control device having a control characteristic of a good response property with no magnetic pole position sensor is provided for a control system of a synchronous motor.
