Document Type and Number:
Japanese Patent JPS6022205
Kind Code:
A
Abstract:
PURPOSE:To perform a proper A/D conversion in response to an operating state by deciding a signal system which performs an A/D conversion with preference and carrying out an interrupting A/D conversion for analog quantity delivered from said signal system when this system is suddenly changed. CONSTITUTION:The channel which performs the next conversion is decided in accordance with a schedule set previously within an ROM72, and a main routine is processed. Then A/D conversions are successively carried out in the order of the throttle opening, the throttle opening, the water temperature, the throttle opening, the intake-air temperature, the throttle opening and so on. Thus the A/D conversion is given again to the throttle opening when the throttle opening has first a sudden change. Then an A/D conversion is given to the water temperature in accordance with a prescribed schedule. Then the A/D conversion is carried out successively for the throttle opening in response to a sudden change of the throttle opening. Thus, the correspondence performance to control is improved.
