Abstract

An electric vehicle control method includes: basic torque distribution processing of determining a basic torque command value for each drive motor based on a total required driving force for the electric vehicle and driving force distribution for each of the drive systems; vibration damping processing of obtaining a corrected torque command value by performing correction for reducing vibration of a driving force transmission system on each basic torque command value; and driving force control processing of controlling a driving force generated by each drive motor based on the corrected torque command value. The vibration damping processing includes estimating whether each of the drive systems is in a dead zone section individually, and adjusting a correction amount for the basic torque command value of the drive system in the dead zone section according to the driving force distribution.
