In this paper, front and rear driving force distribution method based on driving force control is proposed. Driving force control has been proposed by authors' research group for a traction control which can generate desired driving force commanded by driver's acceleration pedal. However, this control method can not completely prevent from reducing driving force when a vehicle runs on an extremely slippery road. If the distance of a slippery road is shorter than vehicle's wheel base, total driving force is retained by distributing the shortage of driving force to gripped wheels. Therefore, front and rear driving force distribution method is proposed for retaining driving force on instantaneous slippery roads. Effectiveness of proposed distribution method is verified by simulations and experiments.
