APPARATUS FOR CONTROLLING HUB MOTOR OF ELECTRIC AUTOMOBILE

摘要

The present invention relates to a device for controlling hub motors of an electric vehicle having hub motors mounted in wheels thereof. The device for controlling hub motors of an electric vehicle according to the present invention comprises an encoder which is mounted in an axis of each of hub motors to measure the rotation angle of the hub motor; a slip-ring torque sensor which is mounted in each of the hub motors to measure torque; a phase comparator which is electrically connected to the encoder to receive the rotation angle variation of the hub motors measured in the encoder and to output a phase difference of the hub motors; and a controller for outputting a control signal optimized for a driver for driving the hub motors based on the phase difference of the hub motors outputted in the phase comparator and the torque information measured in the slip-ring torque sensor.
