Abstract

A controllerincludes a calculation unitthat receives the current sensor value Aof the vehicle and calculates an injection amount based on the current sensor value Aand a target value of the ammonia adsorption amount of the selective reduction catalystso that the ammonia adsorption amount approaches the target value, and a prediction unitthat receives the current sensor value Band calculates a corrected target value by future prediction based on the current sensor value B. The calculation unitcalculates the injection amount based on the corrected target value calculated by the prediction unit
