Abstract
A control method for four wheel drive vehicles in which the front and rear wheels are not mechanically linked controls the drive torque to the vehicle wheels in proportion to vehicle loading and road surface friction coefficients in response to front and rear wheel speeds and front and rear wheel accelerations thereby reducing wheel spin.
