  • Patent number: 10648391
    Abstract: A controller estimates a first estimated adsorption amount which is an amount of adsorption of ammonia in the SCR catalyst at the time when the SCR catalyst is assumed to be in a predetermined abnormal state, estimates a second estimated adsorption amount at the time when the SCR catalyst is assumed to be in a predetermined normal state, calculates a first slip development temperature based on the first estimated adsorption amount, and calculates a second slip development temperature based on the second estimated adsorption amount. The controller, when carrying out an abnormality diagnosis based on a concentration of ammonia in an exhaust gas at the downstream side of the SCR catalyst, carries out diagnostic temperature control so as to control the temperature of the SCR catalyst to a temperature which is equal to or more than the first slip development temperature and is less than the second slip development temperature.

  • Patent number: 10650775
    Abstract: A display control device includes an image creating unit, a display output unit, an update time measuring unit, and a blinking control unit. The blinking control unit determines a bright time and a dark time to be integral multiples of an update time so that a blinking frequency is within a tolerance frequency range. In a blinking control, the blinking control unit executes an on-display control to instruct the image creating unit to create a bright image for a number of times of a value obtained by dividing the bright time by the update time, and then executes an off-display control to instruct the image creating unit to create the dark image for a number of times of a value obtained by dividing the dark time by the update time, and repeats the on-display control and the off-display control until the blinking control ends.
