Abstract
An in-vehicle electronic control unit (ECU) for correcting an error introduced to a sensor output signal as a result of amplification is provided. An output voltage of first and second voltage generators and after-amplification voltages of such output voltages are respectively A/D converted for input into a linear function. A microcomputer adjusts the output voltage of the first and second voltage generators which are amplified by the amplification circuit so that the output signals of the first and second voltage generators are adjusted to increase a voltage difference between the two. The increased voltage difference allows accurate identification of the linear function and removal of the error that is introduced to the sensor output signal during the course of processing by the amplification circuit.
