Abstract
In forced regeneration control of an exhaust gas purification device, data for control such as the number of meshes of a data map and the number of data maps for forced regeneration control is reduced and occurrence of torque shock is avoided by smoothly changing a fuel pressure. In the forced regeneration control of the exhaust gas purification device, when an operation state of an internal combustion engine is in a high-load operation state, normal injection control by stopping multi injection is carried out and according to a rotation speed and a load of the internal combustion engine, a region for control is divided into a multi-injection control region, a transition region, and a normal injection control region, and in the transition region, data for fuel pressure control obtained by interpolation of data for fuel pressure control on the multi-injection control region side and data for fuel pressure control on the normal injection control region side is used.
