PURPOSE:To reconcile an improvement in traction performance at the time of high lateral acceleration turning by low, medium speed traveling and an improvement in tuning stability at the time of this high lateral acceleration turning by high-speed traveling in a favorable manner as preventing a sudden change in car behavior in a transition period when lateral acceleration varies, in a differential limiting torque controller which electronically controls the differential limiting torque to be imparted to an interval between both symmetrical driving wheels on the basis of accelerator opening information. CONSTITUTION:In this controller, a control gain setting means (g), which sets a lateral acceleration sensitive control gain with a body speed sensitive lateral acceleration gain by a value being the lower, the higher in body speed in a high body speed range and a control gain maximum value, is installed there, and then an accelerator opening sensitive target torque by a value increasing at a variation determined by this control gain, insomuch that an accelerator opening detected value out of an accelerator opening detecting means (b) is large enough, is operated. In addition, an accelerator opening sensitive differential limiting control means (i) outputting a control command getting this accelerator opening sensitive target torque to a differential limiting torque imparting means (a), is installed as well.
