Abstract
A urea solution after-treatment system may include a controller which receives urea solution detection information of a urea solution storage tank () storing a urea solution supplied to an SCR (Selective Catalytic Reduction) () for removal of NOx, the controller classifying the urea solution detection information into urea solution state information and then classifying the classified urea solution state information into output signals corresponding thereto, the controller outputting the classified output signals as pattern signals of urea solution shortage, urea solution exhaustion, and urea solution failure, and an accelerator pedal () which generates touch recognition patterns varying according to the pattern signals when the pattern signals are input, and transfers the touch recognition patterns using a touch felt by a driver's foot.
