  • Throttle learning control apparatus
    Patent number: 9593636
    Abstract: There is obtained a throttle learning control apparatus that raises the reliability of throttle fully closed and opened learning even when a self-shutoff delay abnormality occurs and can suppress various defects that occur when a throttle fully closed learning value or a throttle fully opened learning value is not updated. After a self-shutoff delay abnormality occurs, an electronic control unit implements fully closed learning 1 and fully opened learning 1 while the engine is operated in a non-engine-stall period and implements fully closed learning 2 and fully opened learning 2 for compensating the fully closed learning 1 and fully opened learning 1. Fully closed learning is completed when the fully closed learning 1 or the fully closed learning 2 has once been implemented; similarly, fully opened learning is completed when the fully opened learning 1 or the fully opened learning 2 has once been implemented.
