摘要：
In an exhaust purifying apparatus for an internal combustion engine on a vehicle, heating control is executed for supplying fuel to exhaust purification catalysts, thereby increasing the catalyst bed temperature. The heating control is suspended when the vehicle is determined to be driving downhill. Adverse influences due to deactivation of the exhaust purification catalysts during the heating control are reliably avoided.
