    Rear Wiper Operation Device and Method of Vehicle
    [11] The present invention relates to a rear wiper operating apparatus and method thereof of a vehicle, and more particularly, to improve the function of the rear wiper to improve the safety and the driver's operability and convenience as well as to improve performance and marketability. It was invented to secure a competitive advantage.
    [12] Generally, a wiper is a general term for wiping snow, rain, or muddy water on the rear windows, side windows, side mirrors, headlamps, etc., starting with the front and rear windshields of a car.
    [13] In general, in the front wiper system, in the case of the washer interlocking wiper which is currently applied to the front wiper and the shield wiper system, the wiper is configured to stop after 2-3 more operations after the washer liquid injection is finished.
    [14] On the other hand, RV vehicles currently on the market are equipped with a rear wiper as standard, but in the case of the applied rear wiper system, it has a washer interlock wiper and an intermittent operation (INT.) Wiper function. It can be operated only by, and the system that automatically controls the wiper speed according to the amount of rain water by rain sensor (raindrop sensor) mounted on the front windshield, such as the front wiper system is not applied.
    [15] As such, in the case of the rear wiper system currently applied to RV vehicles or H / B (5-door) vehicles, the intermittent wiper is a wiper with a fixed resistance value regardless of the amount of rainwater or when the driver manually activates the operation switch. Is operated at a constant speed, so if the first rain falls a lot (i.e. heavy rain), the driver's rear clock dims and affects safe driving, and the second rain falls very little (i.e. small rain drops). Since the wiper operation switch must be operated manually, it affects the safe operation, and if the automatic switch is operated continuously in a small amount of rain, the wiper blade can be prematurely worn or the durability will be reduced. Since there is no automatic wiper speed control function using rain sensor, There are problems such as ha.
    [16] SUMMARY OF THE INVENTION The present invention has been made to solve such problems in the related art, and it is possible to automatically change the driving time and driving speed of the rear wiper in response to the detection of the amount of rainwater, thereby improving safety by improving the function of the rear wiper. It is possible to increase the operability and convenience of the driver as well as to provide a rear wiper operating device and a method for operating a rear wiper that can secure a competitive advantage through improved rear wiper performance and merchandise.
    [17] The above object of the present invention is to output a relay " off " signal after about 3 seconds when " on " and " washer switch off " after a certain time (T1) when the rear washer switch " on ", and the rear wiper switch " on " Outputs the relay "on" signal, and at the time of rear intermittent operation switch "on" immediately after wiper relay "on" signal output, the wiper is controlled according to the time interval set inside when the front wiper automatic switch "off", Front wiper automatic switch "on" outputs "on" signal to the rain sensor low-speed relay. When the front wiper is operated twice, the rear wiper outputs "on" signal once, and the front wiper automatic switch "on" & rain sensor low speed relay. Continued output "on" rear wiper interval is fixed at 1 second, automatic front wiper switch "on" & rain sensor high speed relay Continue output "on" rear wiper keeps on It can be achieved by.
    [18] Therefore, the rain sensor can detect the rain and automatically change the driving time and driving speed of the rear wiper, improving safety (rear view) by improving the function of the rear wiper, and improving the driver's operability and convenience. In addition to improving the rear wiper performance and marketability, the company can gain a competitive edge.
