Title:
Control device
Document Type and Number:
Japanese Patent JP6176003
Kind Code:
B2
Abstract:
A control device that can realize low power consumption even if the temperature of a wire is erroneously calculated. A control unit calculates, for each of one or more wires, a temperature difference between an ambient temperature of the wire and a temperature of the wire over time, and supplies/interrupts an electric current that flows through the wire. The control unit interrupts, for each of the wires, the electric current if the temperature sum of the calculated temperature difference and the ambient temperature is greater than or equal to a first threshold. The control unit measures a time period in which the electric current is being interrupted. If, for each of the wires the calculated temperature difference is less than a second threshold or the measure time period exceeds a predetermined time period, the control unit halts the calculation of the temperature of the wires.
