AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2012/023305
Kind Code:
A1
Abstract:
Provided is a method characterized by distributing a drive torque to right and left wheels of front and back wheels while taking into consideration not only a load shift in a vertical direction but also a load shift in a lateral direction which is caused at the time of cornering. The load shift is estimated by detecting elements in three axis directions, that is, a vertical and lateral direction acceleration, a yaw rate, and a steering angle, and a friction coefficient of a road surface. The effectiveness of the drive torque distribution method proposed has been verified by performing simulation with software of Matlab/Simulink and CarSim by using a simulator equivalent to a trial production FRID EV. The method should be essential to upgrade the running performance of FRID EV.
