Brake negative pressure control apparatus and method, and engine control unit for internal combustion engine |
摘要 |
A brake negative pressure control apparatus and method, and an engine control unit for an internal combustion engine are provided for ensuring a negative pressure within a brake booster and a stable combustion while avoiding a complicated control. The brake negative pressure control apparatus comprises a negative pressure sensor for detecting a negative pressure within the brake booster, and an ECU for disabling the combustion mode to be set to the stratified combustion when the detected negative pressure is lower than a first predetermined negative pressure. The ECU controls a throttle valve opening in accordance with a target throttle valve opening in a homogeneous combustion mode when the ECU disables the combustion mode to be set to the stratified combustion.
