ABSTRACT:
A throttle valve control block in a microcomputer has a processing load judging means for judging a processing load status of the microcomputer, and an AD converting means for converting an analog opening degree detection signal and outputting a digital opening degree detection signal. The AD converting means has a first conversion mode in which the digital conversion is carried out with high conversion precision, and a second conversion mode in which the digital conversion is carried out with conversion precision lower than the first conversion mode. The first and second conversion modes are set to be switchable to each other, and also switched by the process load judging means.
