  • Oil temperature estimation apparatus and oil temperature estimation method
    Patent number: 12152727
    Abstract: An oil temperature estimation apparatus that estimates an oil temperature of a driving system of a vehicle includes a vehicle speed sensor, a saturated oil temperature acquirer, an oil temperature deviation acquirer, an oil temperature feedback value acquirer, and an estimated oil temperature acquirer. The saturated oil temperature acquirer acquires a saturated oil temperature in a running state of the vehicle at least including a vehicle speed based on the running state. The oil temperature deviation acquirer acquires an oil temperature deviation between the saturated oil temperature and an estimated oil temperature previous value. The oil temperature feedback value acquirer acquires an oil temperature feedback value based on the oil temperature deviation and the vehicle speed. The estimated oil temperature acquirer acquires an estimated oil temperature current value based on the estimated oil temperature previous value and the oil temperature feedback value.
