Negative pressure control apparatus and method therefore in an internal combustion engine |
| abstract |
An apparatus and method control a negative pressure in an internalncombustion engine (10) equipped with a brake booster (18) that uses a negativenpressure produced on a downstream side of a throttle valve (36) provided in an intakenpassage (34) of the engine, as a power source for amplifying the pedal pressing force.nA controller (12) of the apparatus or method determines whether a negative pressurenapplied to the brake booster has reached a predetermined level when the internalncombustion engine is started, and, if the negative pressure has not reached thenpredetermined level, increases an operating speed of the engine to a predeterminednhigh speed and then keeps the throttle valve in a small opening state in which annopening amount of the throttle valve is smaller than that established when the internalncombustion engine is in a fast idle state, during a period of time in which the enginenproceeds to a steady-state operating mode. |
