DESIGNING HARDWARE-IN-THE-LOOP MODEL FOR TRACTION CONTROL SYSTEM ON THE VEHICLE

When the vehicle moves on a complicated road, the active wheels on both sides receive different torque values from the engine transmission down due to the distribution law of the differential in the active axle. Traction control in automobiles is the process of controlling the transmission torque from the engine to the active wheels so that it is suitable for the grip state of the tire and the road surface to avoid the loss of engine torque. In this paper, the research team designs a Hardware-in-the-Loop (HIL) model to control the traction of the automobile when moving in a straight line with different resistances on both sides of the active wheel, designing a traction controller with two sets of brake and engine torque controllers. Experimental results show that the traction control process achieves the expected effect of the designed Hardware-in-the-Loop model.
