| description | PROBLEM TO BE SOLVED: To provide a control method of an exhaust gas purification system, and the exhaust gas purification system capable of sufficiently combusting and eliminating accumulated PM captured by a DPF even when forced regeneration is restarted after interruption was made during a forced regeneration regarding regeneration of a DPF device, and efficiently regenerating the DPF. SOLUTION: In the exhaust gas purification system equipped with the DPF device, when restarting after interrupting a forced regeneration, a forced regeneration is started from the beginning when at least one of the following conditions is fulfilled: a captured amount region Rpj detected by a captured amount region detecting means 32C is a captured amount region having a higher captured amount than a captured amount region Rpi of immediately after interruption; or a traveling distance region Rmj detected by a traveling distance region detecting means 33C is another traveling distance region having a larger amount of traveling distance than the traveling distance region Rmi of immediately after interruption. When neither of the conditions are fulfilled, forced regeneration is performed for the remaining time of the last forced regeneration control continuing from the last forced regeneration.
