Driving force distribution control system and vehicle having the driving force distribution control system

摘要

A correction coefficient setting unit calculates as a difference in an actual revolution speed the difference between the actual revolution speed of a front driving axle and the actual revolution speed of a rear driving axle. Moreover, the correction coefficient setting unit calculates the ideal reference revolution speed of the front driving axle and the ideal reference revolution speed of the rear driving axle in consideration of a difference in a radius of gyration between the driving axles. The correction coefficient setting unit also calculates as a difference in a reference revolution speed the difference between the ideal reference revolution speed of the front driving axle and the ideal reference revolution speed of the rear driving axle. The correction coefficient setting unit then corrects a previous correction coefficient relevant to a transfer clutch set in the basic clutch tightening force correction unit according to the difference in an actual revolution speed and the difference in a reference revolution speed.
