Pumping brake detection and control device and method for internal combustion engine |
摘要 |
A device includes: actual-intake-pipe-pressure detection unit (11); estimated-intake-pipe-pressure detection unit (12) for calculating an estimated intake pipe pressure based on a rotation speed of the engine and an opening degree of a throttle valve; pressure difference calculation unit (13) for calculating a pressure difference between the actual and estimated intake pipe pressures; pressure difference integration unit (14) for integrating the pressure difference with respect to time; pumping brake detection unit (15) for determining that a pumping brake operation is performed when a integral value is equal to or more than a first determination value; and throttle valve control unit (16) for carrying out control for the pumping brake during the pumping brake operation based on a result of the determination by the pumping brake detection unit (15), and carrying out ordinary control otherwise. |
