Improving Stability and Controllability of Two-Axial Vehicles with a Connectable Front Axle by Redistributing Torque between the Axles

The most common schemes of 4х4 drives are those where the front axle is permanently fixed to the drive shaft and the back axle can be connected selectively. Control algorithms for such transmissions are well established. Two-axle vehicles with a connectable front axle are rarer, and questions related to increasing their road stability through redistribution of torque between the axles are studied considerably less. The authors propose a method of increasing stability and controllability of 4x4 vehicles with a connectable front axle by redistributing torque between the axles. The efficiency and performance of the proposed method is confirmed by the simulation of motion of such two-axle vehicles.
