  • Motion control apparatus for four-wheel drive vehicle
    Patent number: 7316457
    Abstract: A motion control apparatus for a four-wheel drive vehicle performs over-steer suppressing control when the vehicle is in an over-steer state so as to apply a braking force to a front wheel located on the outer side of a turning locus without lowering engine output, and performs LSD control for the front/rear wheels when the obtained difference between wheel speeds of the left and right wheels exceeds an allowable limit so as to apply a braking force for suppressing idle rotation to the one of the left and right wheels that is of higher wheel speed. During execution of the over-steer suppression control, the braking force for suppressing front-wheel idle rotation to be imparted to the front wheel located on the inner side of the turning locus by means of the front-wheel-side LSD control is lowered, whereby the rear wheels become unlikely to produce excessive idle rotation.
