4WD CONTROL SYSTEM FOR SENSING WEATHER CHANGE, CAPABLE OF PREVENTING VEHICLES FROM SLIPPING DUE TO DEEP SNOW

摘要

PURPOSE: A 4WD control system for sensing weather change is provided to sense the rainfall from a rain sensor and to control the 4WD system for distributing a driving power by sensing the temperature from a temperature sensor and calculating the temperature.;CONSTITUTION: A 4WD control system for sensing weather change controls a four-wheel-drive-car. The four-wheel-drive-car transfers driving power to the other side wheel through a clutch for distributing a torque while directly transferring the driving power to a front wheel or a rear wheel. The four-wheel-drive-car controls a 4WD controller according to a driving state of the car. The four-wheel-drive-car comprises: a detection unit(100) for sensing the weather; a weather change sensing unit(200) which receives a car speed, the rainfall, the temperature of atmosphere, and a speed difference of the front wheel and the rear wheel from the detection unit; and a driving power distribution unit(300).;COPYRIGHT KIPO 2010
