Title:
TORQUE DISTRIBUTION CONTROLLER FOR FOUR-WHEEL DRIVE VEHICLE
Document Type and Number:
Japanese Patent JPS62279129
Kind Code:
A
Abstract:
PURPOSE:To suppress the wheel spin to the min. by installing a means for judging either of the front or rear wheels has the wheel spin tendency and reducing the driving torque to the axle on the side where the wheel spin tendency is provided. CONSTITUTION:A torque distribution controller 16 receives the signals omega1-omega4 of the revolution speed sensors 11-14 for the front wheels 3 and rear wheels 4, and omega1+omega2 and omega3+omega4 are obtained. An operation state judging means 22 judges any of the states of straight advance, low speed turn, and high speed turn on the basis of the signals supplied from the revolution speed sensors 11-14 and a steering wheel angle sensor 19. A comparing means 25 compares the input signals and judges either of the front wheels 3 and rear wheels 4 has the wheel spin tendency. Then, the driving torque to the wheel spin tendency side is reduced according to the result, and the driving torque to the other is increased. Thus, the wheel spin can be suppressed.
