Abstract: A vision based intelligent smart wiper system and its control method are provided to control operation of a wiper effectively by identifying various situations like raindrops on a local area of a windshield or drizzly or heavy raining and so forth. In a vision based intelligent smart wiper system, a wiper switch(14) turns on/off a wiper(11). An LED(16) irradiates light to a sensing area. A vision camera(17) recognizes the light reflected from the sensing area of a windshield(13). A fuzzy controller controls an operation speed and a cycle of the wiper by calculating a water level and a distribution degree. A wiper operational motor(12) controls the operation speed and cycle of the wiper.

Abstract: PURPOSE: A fault-tolerance system and a method thereof are provided to actively perform a count measure on a fault which is generated in control system of a vehicle or a ship. CONSTITUTION: A threshold estimating unit(110) predicts a threshold estimating value for a fault detection. The fault detection unit acquires the predicted threshold value as an estimating value. A fault detection unit(120) detects a fault in each input value based on the threshold value, and the estimating value. The fault detection unit outputs an input value which has no fault detection as a first result value.

Abstract: PURPOSE: A method and a system for allowing defects are provided to maintain a normal state for a constant period of time in case of the occurrence of the defects in order to detect and eliminate the defects. CONSTITUTION: A threshold value prediction part(110) predicts a threshold value. A defect detecting part(120) detects the occurrence of defects. If there is no defect in at least one of a plurality of input values, the defect detecting part outputs a first result value. If the entire input values have defects, an exception processing part(130) calculates a second result value based on the finally fed back output value of a previous cycle. An output voter part(140) determines the final output value of a current cycle based on the first result value and the second result value.

CONSTITUTION: A fault- tolerance method comprises an estimation stage, a detection step, and a determining step. In the estimation stage, a threshold value for deciding a confidence range is produced(S310). In the detection step, at least one input value is detected whether it is included in the confidence range(S320). In the determining step, the output value corresponding to the input value is decided(S340). In the estimation stage, the estimation value of a current input value is calculated by using the previous output value. In the estimation stage, threshold value is calculated by using the estimation value and the previous output value.
