A rain sensor is included in a vehicle, and a method for controlling the vehicle utilizes the rain sensor. The rain sensor includes a light transmitter configured to radiate light to a windshield of the vehicle; a light receiver configured to receive light reflected from the windshield to generate a reception light signal; a filter configured to filter out noise from the reception light signal; and a controller configured to determine a presence or absence of pollutant and a degree of pollution on the basis of the filtered reception light signal, and perform pollutant removing.

Rain sensor, vehicle using the same, and method for controlling the vehicle

A rain sensor of a vehicle and a control method thereof are provided to solve a problem that a measurement result of rainfall varies according to a glass specification of a windshield even under the same rainfall condition by tuning sensitivity of the rain sensor in accordance with the glass specification of the windshield. For this, a method of determining the glass specification of the rain sensor includes determining the glass specification of the windshield from a light-receiving signal obtained by receiving light reflected by the windshield of the vehicle, and eliminating a deviation between light-receiving signals by glass specification, which is caused by a difference in the glass specification, by applying parameter tuning according to a glass specification to the light-receiving signal.
