Title:
VEHICULAR DRIVE FORCE DISTRIBUTION APPARATUS
Document Type and Number:
Japanese Patent JP2015077906
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To control drive force distribution appropriately in accordance with a theoretical normative model and prevent a tight-corner braking phenomenon.SOLUTION: A basic distribution ratio calculation part (60) calculates a basic distribution ratio (BDR) of drive force between front and rear wheels on the basis of a load exerted on front and rear wheels of a vehicle. Servo control means (70, 80) performs servo control for modifying so as to increase or decrease the basic distribution ratio (BDR) on the basis of a difference (DNR) between a front-rear wheel rotation speed difference target value in accordance with a travel state of the vehicle and a front-rear wheel rotation speed difference measurement value. An adjustment part (90) applies an adjustment so that drive force distribution to a rear wheel indicated by a post-modification distribution ratio modified by the servo control means does not exceed total drive force. For example, "1-BDR" is calculated by a gain coefficient for adjustment, and a gain of the signal (DNR) based on the difference is adjusted in accordance with the gain coefficient.
