  "textContent": "In a case where deceleration of a vehicle is detected while a temperature of a filter is higher than a reference temperature, when the temperature of the filter has continued to be higher than the reference temperature for a reference period or longer, a decrease in a flow rate of exhaust gas flowing into the filter is suppressed by operating exhaust gas flow rate decrease suppression means (S105), and when the temperature of the filter has continued to be higher than the reference temperature for a period shorter than the reference period, the exhaust gas flow rate decrease suppression means is prohibited from being operated (S106). Thus, it is possible to suppress an unnecessary decrease in the temperature of the particulate filter while suppressing an excessive increase in the temperature of the particulate filter.",
