ABSTRACT:
A traction control system for a motor vehicle has an engine with a catalytic converter in an exhaust path. The traction control system has wheel speed sensors for detecting wheel speeds of respective wheels, a slip amount detection device for calculating slip amounts in driven wheels based on the wheel speeds, an engine output controller for decreasing engine output based on predetermined engine output decreasing patterns which correspond to the slip amounts, and an octane number detection device for detecting a difference in octane numbers of fuel between fuel designated in the engine and fuel actually supplied to the engine. The engine output decreasing pattern is changed so as to decrease unburned hydrocarbons in the exhaust gas flown into the catalytic converter when the octane number of the actually supplied fuel is more than a predetermined number smaller than that of the designated fuel.
