Abstract:
Abstract. The automotive differential is a mechanism that splits the engine power to the two drive wheels into the left and right sides of the drive axles and allows the driven wheels of a vehicle to have different speeds while they are turning. When a vehicle moves straight on the same road friction at the two drive wheels, the differential applies the same amount of power to each drive wheel. However, if one of the drive wheels rolls on the skid road, the differential splits more the engine power to this wheel. As this wheel slip on the roads, the engine power is dissipated due to the friction between the road and tire. The solutions to this problem are using the limited-slip differential, the active differential. They allow more power to transmit to the non-slipping wheel. In this paper, the authors use the braking torque applied to the slipping wheel to redistribute the engine power on two drive wheels and design a controller based on the PID controller for traction control. The simulation result shows the efficacy of the designed controller.
