Abstract
A wiper driving apparatus according to embodiments comprises: a sensor unit including a carbon micro coil; a precipitation amount sensing unit for outputting an output value corresponding to the value of a difference between a first frequency and a preset second frequency according to a change in the impedance value of the sensor unit; and a control unit for determining whether there is precipitation and the amount of precipitation by using the output value output through the precipitation amount sensing unit, and determining wiper driving conditions according to the determined results, wherein the first frequency is changed to correspond to a change in the inductance value of the carbon micro coil according to whether there is precipitation and the amount of precipitation.
