Title:
CONTROL METHOD FOR ELECTRIC VEHICLE AND CONTROL DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2023128462
Kind Code:
A
Abstract:
To provide a control method for electric vehicle and a control device for electric vehicle that can suppress vibrations that a vehicle has even when one drive shaft comprises a drive power transmission mechanism which transmits composite power of a plurality of electric motors to drive wheels.SOLUTION: When a drive power transmission mechanism inputs a total torque quantity which is the sum of torque command values to a vehicle model obtained by modeling characteristics assuming that a plurality of electric motors are a body of inertia which rotates in one body so as to calculate a parameter correlating with rotary motion of the vehicle model, and corrects the total torque quantity based upon a correction quantity obtained by multiplying the parameter by a predetermined gain so that the rotary motion is a norm response, distribution gains summed up to the gain are individually set to the electric motors, and the torque command values are individually corrected based upon a distribution correction quantity obtained by multiplying the parameter by the distribution gains.SELECTED DRAWING: Figure 4
