IMPLEMENTATION OF FOUR WHEEL DRIVE VEHICLE DYNAMICS USING MATLAB SIMULINK

Abstract

A four-wheel drive vehicle model, from drive shaft and differential to tire and road dynamics. There are almost as many different types of four-wheel-drive systems as there are four-wheel-drive vehicles. It seems that every manufacturer has several different schemes for providing power to all of the wheels. Four-wheel drive - Usually, when carmakers say that a car has four-wheel drive, they are referring to a part-time system. For reasons these systems are meant only for use in low-traction conditions, such as off-road or on snow or ice. All-wheel drive - These systems are sometimes called full-time four-wheel drive. All-wheel-drive systems are designed to function on all types of surfaces, both on- and off-road, and most of them cannot be switched off. The best system will send exactly the right amount of torque to each wheel, which is the maximum torque that won't cause that tire to slip.
