OIL TEMPERATURE ESTIMATION APPARATUS AND OIL TEMPERATURE ESTIMATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18200176 titled 'OIL TEMPERATURE ESTIMATION APPARATUS AND OIL TEMPERATURE ESTIMATION METHOD
Simplified Explanation
The patent application describes an apparatus for estimating the oil temperature of a vehicle's driving system. Here are the key points:
- The apparatus includes various components such as 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 determines the saturated oil temperature during vehicle operation, taking into account factors like vehicle speed.
- The oil temperature deviation acquirer calculates the difference between the saturated oil temperature and the previously estimated oil temperature.
- The oil temperature feedback value acquirer determines an oil temperature feedback value based on the oil temperature deviation and the vehicle speed.
- The estimated oil temperature acquirer calculates the current estimated oil temperature using the previous estimated oil temperature and the oil temperature feedback value.
Original Abstract Submitted
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.
