Differential limiting control apparatus for four-wheel drive vehicle

摘要

Restraining torque TF of an electronic controlled front limited slip differential (5) arranged between right and left front wheels is controlled in accordance with controlling right-left wheel rotational speed difference &Dgr;NF, which is the rotational speed difference between the right and left front wheels, while restraining torque TC of an electronic controlled coupling (8) arranged between the front and rear wheels is controlled in accordance with controlling front-rear wheel rotational speed difference &Dgr;NC obtained by subtracting ½ of the rotational speed difference between the right and left wheels (|&Dgr;NF|/2) from the rotational speed difference (&Dgr;NCT−&Dgr;NCD) between the front and rear wheels.
