Abstract
It is an object of the present invention to provide a controlling apparatus for throttle valve that detects a throttle open degree enabling more appropriate controls by removing ill effects of multiplexing an idle control in controlling data. The idle control amount is canceled by subtracting the idle target open degree from the detected throttle open degree. Further, in order to correct differences of the detected data due to a response delay of the throttle valve, the previous measured value is regarded as the detected throttle open degree when the response delay occurs.
Claims4
A driving controlling apparatus for an internal combustion engine having a throttle valve in which a throttle open degree is controlled to become a throttle target open degree, where driving controls to the internal combustion engine are conducted based on the throttle open degree, the throttle open degree required when idling is set as an idle target open degree, an accelerator target open degree in response to the accelerator operation is set, a throttle target open degree is set including both the idle target open degree and the accelerator target open degree, comprising:
- throttle open degree detecting means for detecting a throttle open degree;
- and
- compensating means for compensating the throttle open degree detected by the throttle open degree detecting means in view of the idle target open degree;
- wherein the driving of the internal combustion engine is controlled based on the throttle open degree compensated by the compensating means.
A driving controlling apparatus for an internal combustion engine where driving controls to the internal combustion engine are conducted based on changes of a throttle open degree, the throttle open degree required when idling is set as an idle target open degree, an accelerator target open degree in response to the accelerator operation is set, a throttle target open degree is set including both the idle target open degree and the accelerator target open degree and a throttle valve is feed-back controlled for the throttle target open degree, comprising:
- throttle open degree detecting means for detecting a throttle open degree;
- and
- compensating means for compensating the throttle open degree detected by the throttle open degree detecting means in view of the idle target open degree;
- wherein the driving of the internal combustion engine is controlled based on the throttle open degree compensated by the compensating means.
