FAILURE DETERMINATION DEVICE FOR TRANSAXLE OIL TEMPERATURE SENSOR

WIPO Patent Application WO/2024/062555

A1

A failure determination device for a T/A oil temperature sensor 30 that detects the oil temperature of a transaxle 7 of a vehicle 1 includes a failure determination unit 31 that determines a failure of the T/A oil temperature sensor 30 on the basis of the oil temperature of the transaxle 7 from the start of the vehicle 1 until a predetermined running condition is established. The failure determination unit 31 makes a first determination to determine that the difference between the oil temperature of the transaxle 7 at the start of the vehicle 1 and the oil temperature of the transaxle 7 when the predetermined running condition is established is less than a first threshold value, and a second determination to determine that an integrated value of the absolute value of the amount of change in the oil temperature of the transaxle 7 per unit time from the start of the vehicle until when the predetermined running condition is established is less than a second threshold value, and where both the first determination and the second determination are satisfied, it is determined that the T/A oil temperature sensor 30 is stuck abnormally.
