An exhaust gas control system ( 1 ) comprised with a continuous regeneration-type DPF ( 13 ), an exhaust throttle valve ( 16 ) and a DPF control means ( 30 C), wherein the regeneration control is suspended, the multi injection control is performed, and the exhaust throttle valve is closed, when detecting a stop condition of the vehicle during the regeneration control of the continuous regeneration-type diesel particulate filter device ( 13 ) by the regeneration means. Thereby, concerning the regeneration of the continuous regeneration-type DPF device ( 13 ), the DPF can be regenerated securely by burning PM efficiently even in a traveling pattern of frequent waiting for the traffic lights to change in urban areas. |
