摘要： A fault detecting apparatus for a four-wheel drive vehicle is provided for avoiding without fail any erroneous detection due to a response delay associated with an operation for switching a speed increasing system and due to sudden fluctuations in wheel speed, to highly accurately detect a fault in the speed increasing system. The speed increasing system is configured to transmit a driving force of a prime mover directly to main driving wheels and to sub-driving wheels through associated clutches, and to increase rotational speed of the sub-driving wheels above rotational speed of the main driving wheels when a speed increase instruction signal is outputted. The fault detecting apparatus comprises an S-AWD•ECU for detecting a fault in the speed increasing system, and for disabling the fault detection until a predetermined time has elapsed after a speed increase instruction signal was outputted or after the output of the speed increase instruction signal was stopped.

摘要： There is provided a control system for a front-and-rear wheel drive vehicle which connects and disconnects one pair of respective pairs of front wheels and rear wheels to and from an electric motor for driving the one pair of wheels by a clutch of a type actuated by pressure. The control system is capable of engaging the clutch promptly and reliably, thereby enabling excellent startability of the vehicle and a sufficient total driving force for the vehicle. In the control system, the front wheels are driven by an engine, the rear wheels are driven by the electric motor via the clutch, and the clutch is actuated by accumulator pressure, whereby the rear wheels and the electric motor are connected to and disconnected from each other. The control system increases the accumulator pressure by driving an electric oil pump when the accumulator pressure is equal to or lower than an operating pressure.

摘要： A driving force control apparatus for a four-wheel drive vehicle is provided for stably launching the vehicle irrespective of whichever condition of a road surface and whether or not a road is gradient. In the driving force control apparatus for a four-wheel drive vehicle configured to transmit a driving force of a prime mover directly to a left and a right main driving wheel and to a left and a right sub-driving wheel through a clutch, rotational speed sensors detect the rotational speed of the respective main driving wheels and sub-driving wheels, a 2/4 WD•ECU sets a fastening force of the clutch in accordance with a difference between the detected rotational speeds of the main driving wheels and the sub-driving wheels, determines that the four-wheel drive vehicle is in a slip stop state when at least one of the detected rotational speeds of the wheels is equal to or lower than a predetermined rotational speed, and corrects the clutch for the set fastening force when it determines that the four-wheel drive vehicle is in the slip stop state.
