ABSTRACT:
A traction control system for an automotive vehicle is provided which controls engine power and braking force to recover traction of wheels when wheel slippage occurs during acceleration. The traction control system has four traction control modes and four control switching modes for switching between the traction control modes smoothly without any mechanical shock. In each of the control switching modes, one of the engine power control and the braking force control is restricted gradually according to its control capacity which is, for example, determined based on a period of time left until the control is prohibited. If the control capacity is decreased undesirably, the control is modified so as to increase the control capacity.
