UREA SELECTIVE CATALYTIC REDUCTION SYSTEM, METHOD AND CONTROLLER USING TOUCH SENSE TO RECOGNIZE UREA SELECTIVE CATALYTIC REDUCTION

摘要

An urea water solution post processing system of the present invention includes a pedal controller (80) outputting the detection information of the urea water solution in an urea water solution tank (20) using pattern signals of a shortage of an urea water solution, the exhaustion of the urea water solution, and a defective urea water solution and an acceleration pedal generating touch recognition patterns different in accordance with the pattern signals and transmitting the patterns using touches to a driver′s foot. The present invention is capable of informing a driver about the shortage of the urea water solution corresponding to an urea water solution residual reference using vibration based on the detection information of the urea water solution tank (20) outputted by the pedal controller (80) and informing the driver about necessity of reinjecting the urea water solution such as the exhaustion of the urea water solution or the defective urea water solution using an increase in a pedal effort of the acceleration pedal (40), thereby informing the driver about a current condition of the urea water solution. Especially, the present invention is characterized by inducing a driver′s action before a halt against a driver′s will to drive when the reinjection of the urea water solution is necessary.
