Abstract
A detection apparatus includes a detection unit, a control unit, a first setting unit, and a second setting unit. The detection unit is disposed in an exhaust path through which an exhaust gas flows, and detects a correlation value correlated with an amount of particulate matter (PM) attaching to an attachment element. The control unit controls a temperature of the attachment element to follow a target temperature while a regeneration process is performed to heat the attachment element so as to burn PM. The first setting unit sets the target temperature to be lower, as the amount of PM becomes larger. The second setting unit sets a completion timing of the regeneration process so that a period of the regeneration process becomes longer, as the amount of PM becomes larger or a temperature of the attachment element becomes lower while the regeneration process is performed.
