APPARATUS FOR IMPROVING ACCURACY OF SENSOR

摘要

The present invention relates to an apparatus for improving precision of a sensor. The apparatus of the present invention includes: a sensor part for sensing an inner/outer situation of a vehicle; a read out IC (ROIC) circuit part connected to an output stage of the sensor part; and a micro controller unit (MCU) for transmitting a control command to the ROIC circuit part by sensing occurrence of an abnormal signal of the vehicle. According to the present invention, a safety device can start controlling at a proper time, according as the ROIC circuit part capable of amplifying an electrical signal outputted from the sensor part by a desired gain and capable of reducing a sampling interval is connected to the output stage of the sensor part. The present invention can prevent generation of unnecessary noise during a process of processing the electrical signal outputted from the sensor part by forming a noise blocking switch at an input stage of the ROIC circuit part.
