Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022036487
Kind Code:
A
Abstract:
To provide a control device capable of properly controlling a temperature of an electric heating-type catalyst.SOLUTION: A control device 10 of an electric heating-type catalyst 200 includes a power supply portion 11 for supplying electric power for heat generation to the electric heating-type catalyst 200, and a temperature acquisition portion 12 for acquiring a temperature of the electric heating-type catalyst 200. The power supply portion 11 determines a target power amount on the basis of temperature change of the electric heating-type catalyst 200 in a period before start of boiling of water component attaching to the electric heating-type catalyst 200, and stops the supply of the electric power for heat generation, to the electric heating-type catalyst 200 when an integrated value of the electric power for heat generation supplied to the electric heating-type catalyst 200 reaches the target power amount.SELECTED DRAWING: Figure 1
