Abstract
A control device for a vehicular differential limiting apparatus is provided, for applying differential limiting torques to a left drive wheel and a right drive wheel of a vehicle during startup and running thereof with favorably suppressing occurrence of deflection of the vehicle. The control device for the vehicular differential limiting apparatus comprises differential limiting torque calculating portion 60 that calculates the differential limiting torques based on a state quantity of the vehicle; differential limiting torque upper-limit guard value calculating portion 62 that calculates differential limiting torque upper-limit guard values based on a preset deflection permit yaw rate and a real yaw rate of the vehicle; and upper limit guard value processing portion 72 that limits the differential limiting torques ΔT calculated by the differential limiting torque calculating portion 60, using the differential limiting torque upper-limit guard values ΔTL calculated by the differential limiting torque upper-limit guard value calculating portion 62, for obtaining differential limiting torques to be applied to the left and right drive wheels. Thus, the most suitable differential lim…
