Engine throttle control apparatus |
摘要 |
<p>The invention ensures that a vehicle responds in accordance with a driver's expectations during negative pressure control (or boost control). A negative pressure control target intake air flow rate is calculated. This air flow rate ensures that the pressure in a cylinder does not drop too low (which could increase oil leakage into the cylinder). A greater one of an ISC (idle speed control) target torque and a negative pressure control target intake air flow rate torque-converted value is selected. The selected torque is set as an engine demand torque. The engine demand torque is combined with a driver demand torque to calculate a target torque. The throttle valve is controlled in an electronic manner based on the target torque. <IMAGE></p> |
