Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022036488
Kind Code:
A
Abstract:
To provide a control device capable of determining abnormality in a power supply circuit for an electric heating-type catalyst.SOLUTION: A control device 10 includes: a heat quantity setting portion 11 for setting a target heat quantity; a power supply portion 12 for performing a power supply processing as a processing for supplying power for power generation to an electric heating-type catalyst 200 so that the set target heat quantity is generated in the electric heating-type catalyst; a temperature acquisition portion 13 for acquiring a temperature of the electric heating-type catalyst 200; and an abnormality determination portion 15 for determining abnormality in a power supply circuit to supply the power for power generation to the electric heating-type catalyst 200. The abnormality determination portion 15 determines the abnormality in the power supply circuit on the basis of comparison of an arrival temperature of the electric heating-type catalyst 200 in performing the power supply processing, with a prescribed threshold temperature.SELECTED DRAWING: Figure 1
