Calculated vehicle direction correction device for compensating drift error |
摘要 |
A correction device (14) corrects an output signal from a relative vehicle direction detection device (13) using a pair of low pass filters with different delay times, providing a pair of output voltages in response to the output signal LF components, which are compared for detecting coincidence within a given error range, for center point potential correction of the output signal, for eliminating drift error.
