    • Disclosed is a technique for detecting a road surface property. More specifically, the technique includes a reflectivity table that stores a degree of reflectivity of a rainy road relative to a reference reflectivity and a degree of reflectivity of a snowy road relative to the reference reflectivity. A reflection measurement unit measures a reflection which is the amount of a laser beam that is emitted through a light emitting unit of a laser sensor, reflected from the road surface, and received by a light receiving unit, and a reflectivity calculation unit calculates a degree of reflectivity for the road in front of the vehicle via a ratio of the measured reflection and the reference reflectivity. A road surface property determination unit then detects the corresponding road surface property based on the reflectivity table.

    • An apparatus for controlling an operation of a reciprocating compressor, includes: a control unit for detecting a current pushed amount of a piston when a TDC is detected as an inflection point of a phase difference between stroke and current, comparing the current pushed amount with a pushed amount reference value, and applying a DC voltage applied to a linear motor based on the comparison result. An AC voltage and a DC voltage are applied to the linear motor to increase the stroke, and when the TDC is detected, the current pushed amount is calculated and compared with the pushed amount reference value, and then, the DC voltage or a DC current applied to the linear motor is varied based on the comparison result, thereby obtaining a maximum compression volume without collision of the piston.
