Abstract
A traction control system for an automotive vehicle performs traction control by controlling an engine having an exhaust system with a catalytic converter and a brake system to reduce driving force delivered to driving wheels, so as to diminish excessive slippage of the driving wheels. The traction control system includes a controller for changing an engine control mode from an ordinary control mode to an exhaust temperature reduction mode when a temperature of the catalytic converter is higher than a predetermined temperature and changing a control parameter of engine control, so that the engine provides an increase in output torque in the exhaust temperature reduction mode.
