Abstract

There is provided a vehicular driving force distribution control apparatus which is configured to control distribution of a driving force of an engine to main and sub driving wheels of a four-wheel drive vehicle. A coupling is configured to change a transmission amount of the driving force from the engine. The driving force of the engine is mainly transmitted to main driving wheels. The driving force of the engine is transmitted to sub-driving wheels via the coupling. An engine control unit is configured to control engine torque of the engine. A rotating speed difference detection unit is configured to detect a rotating speed difference between the main driving wheels and the sub-driving wheels. A coupling control unit is configured to control the transmission amount which is transmitted by the coupling, depending on the rotating speed difference detected by the rotating speed difference detection unit. When the rotating speed difference detected by the rotating speed difference detection unit is a setting value or larger, a first reduction control of reducing an amount of the engine torque is executed by the engine control unit. When it is determined that the first reduction control is continuously executed for a setting time or longer, a second reduction control of reducing the transmission amount which is transmitted by the coupling is executed by the coupling control unit.
