Abstract
A device, and a corresponding method, for controlling a wiper of a vehicle may include: a storage that stores a reference table, wherein each wiper operation mode corresponding to each rainfall and each sensitivity level is recorded in the reference table; a rain sensor that measures the rainfall; a wiper switch that receives a wiper operation mode and a sensitivity level input from a driver; and a controller that detects a wiper manipulation pattern of the driver based on the measured rainfall and that changes the reference table to a driver-customized-table based on the wiper manipulation pattern of the driver.
Claims15
A device for controlling a wiper of a vehicle, the device comprising:
- storage configured to store a reference table, wherein each wiper operation mode corresponding to each rainfall and each sensitivity level is recorded in the reference table;
- a rain sensor configured to measure the rainfall;
- a wiper switch configured to receive a wiper operation mode and a sensitivity level input from a driver;
- and
- a controller configured to
- detect a wiper manipulation pattern of the driver based on the measured rainfall,
- change the reference table to a driver-customized-table based on the wiper manipulation pattern of the driver, and
- control the wiper of the vehicle based on the reference table,
- wherein detect the wiper manipulation pattern includes:
- identify propensity of the driver when the wiper operation mode is changed or the sensitivity level is changed,
- allocate a score to each of the operation modes of the wiper and the sensitivity levels and to identify propensity C of the driver based on a following [Equation 1]:
- C=Wa(a2−a1)+Wb(b2−b1) [Equation 1]
- wherein a1 means a score for a previous wiper operation mode, a2 means a score for a current wiper operation mode, b1 means a score for a previous sensitivity level, b2 means a score for a current sensitivity level, Wa means a positive weight, and Wb (Wa>Wb) means an applied positive weight.

A method for controlling a wiper of a vehicle, the method comprising:
- storing, by storage, a reference table, wherein each wiper operation mode corresponding to each rainfall and each sensitivity level is recorded in the reference table;
- measuring, by a rain sensor, the rainfall;
- receiving, by a wiper switch, a wiper operation mode and a sensitivity level input from a driver;
- detecting, by a controller, a wiper manipulation pattern of the driver based on the measured rainfall;
- changing, by the controller, the reference table to a driver-customized-table based on the wiper manipulation pattern of the driver;
- and
- controlling the wiper of the vehicle based on the reference table
- wherein the detecting of the wiper manipulation pattern of the driver includes:
- identifying propensity of the driver when the wiper operation mode is changed or the sensitivity level is changed;
- identifying the propensity of the driver a reference number of times;
- and
- accumulating the identified propensity of the driver to detect the wiper manipulation pattern of the driver,
- wherein the identifying of the propensity of the driver includes:
- allocating a score to each of the operation modes of the wiper and the sensitivity levels;
- and
- identifying propensity C of the driver based on a following [Equation 1]:
- C=Wa(a2−a1)+Wb(b2−b1) [Equation 1]
- wherein a1 means a score for a previous wiper operation mode, a2 means a score for a current wiper operation mode, b1 means a score for a previous sensitivity level, b2 means a score for a current sensitivity level, Wa means a positive weight, and Wb (Wa>Wb) means an applied positive weight.
