Abstract

A control unit () calculates a temperature difference (ΔTg). The temperature difference (ΔTg) is a value obtained by subtracting the temperature (Tg) of a GPF () from a target GPF temperature (Tgt). If the temperature difference (ΔTg) is less than or equal to zero, the control unit () implements a fuel economy-oriented conventional control. If the temperature difference (ΔTg) is greater than zero, the control unit () implements a filter temperature-increasing control. The filter temperature-increasing control causes the exhaust temperature to be increased so that the temperature (Tg) of the GPF () becomes greater than or equal to the target GPF temperature (Tgt).
