Significant role is played by traction control system (TCS) in road vehicles, because slip occurs during driving on wet road or snowy surface. However, it is very dangerous to drive on the icy or snowy road without traction control system, because in that condition the vehicle can lose its path. In such condition, to control a vehicle is very difficult task for drivers. Drivers can regulate easily the traction torque of vehicle driving on difficult surface by using TC system. It also makes our journey safe. Owing to such system high way automation system can be made safer. In high way automation system it plays very crucial role as well. Therefore, TCS estimates the slip of each wheel and distribute traction torque between the wheels. Thus, it makes better the longitudinal performance of a given vehicle. In simulation it is analyzed that traction control system plays important role in road vehicles. So, there are four different cases of traction torque distribution shown while driving on different road conditions. Therefore, traction torque is distributed with respect to the slip of each wheel. In case of increasing slip in either of the wheel the traction torque will be distributed accordingly. Actually, in the given system a torque is distributed corresponding to the slip of each wheel. When a wheel loses its traction then traction control system activates and minimizes the torque of the given wheel. In contrast, it will involve maximum traction torque to opposite wheel. Similarly, it can be observed that traction torque will be reduced to the wheel which is spinning. Control system will observe the whole phenomenon of slip and distribute traction torque either high or low according to the value of slip. However in this research work cost effective and very simple techniques are adopted.
