Document Type and Number:
WIPO Patent Application WO/2019/186757
Kind Code:
A1
Abstract:
An electric vehicle control device 1 is provided with: a signal receiving unit 11 for receiving a signal coming at intervals in accordance with the rotational speed of a motor 3; a rotational speed calculation unit 12 for calculating an instantaneous rotational speed of the motor 3 on the basis of the signal interval ΔT between a sensor signal S1 and a sensor signal S2; and a motor control unit 13 for generating a PWM signal on the basis of the calculated instantaneous rotational speed. When the variation of the instantaneous rotational speed is greater than or equal to a specific value, the motor control unit 13 corrects the duty ratio of the PWM signal on the basis of the instantaneous rotational speed so that the output voltage of a power conversion unit 30 becomes a value in accordance with the instantaneous rotational speed.
