DIAGNOSIS DEVICE FOR TEMPERATURE SENSOR

摘要

A diagnosis device for a temperature sensor provided to a power transmission device transmits driving force generated by a driving power source of a vehicle. The diagnosis device includes: an output voltage estimating unit to calculate an output voltage estimation value of the temperature sensor, based on the operating state of the vehicle; and an output voltage stuck malfunction determining unit to determine an output voltage stuck malfunction of the temperature sensor, in a case where the amount of change of the output voltage estimation value is equal to or above a first threshold value, and the amount of change of output voltage of the temperature sensor is equal to or below a second threshold value.
