摘要
Every time a specified period of time is counted during execution of filter regeneration control, a PM remaining amount every time that the specified period of time passes is estimated by subtracting the product of the specified period of time, a PM removal rate per unit time, and a PM remaining amount at the point when the specified period of time started to be counted from the PM remaining amount at the point when the specified period of time started to be counted. As a result, the PM remaining amount during execution of filter regeneration control which oxidizes and removes particulate matter that has accumulated on a particulate filter is estimated with greater accuracy.
