Title:
CONTROL APPARATUS AND CONTROL METHOD FOR ELECTRICALLY DRIVEN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/071014
Kind Code:
A1
Abstract:
Provided are a control apparatus and a control method for an electrically driven vehicle, wherein the difference between the driving forces of the left and right driving wheels is made to be approximately zero, even when the effective radii of the left and right wheels become different such as when the air pressures of the tires change, to suppress the generation of turning force, and improve driving stability. A correcting means (14) is provided for correcting command values to be given, by a drive command outputting means (13), to drive circuits (11) of motors (4) of the left and right driving wheels (2). This correcting means (14) receives input of the steering angle and the rotational speed and motor current of each of the driving wheels (2), uses the steering angle as a proceeding direction reference, and implements correction such that the command values given to the left and right driving wheels (2) are in a relation that suppresses generation of turning force upon the vehicle due to the difference in the effective diameters of the left and right driving wheels (2).
