Title:
OIL PUMP CONTROL METHOD
Document Type and Number:
Japanese Patent JP2016061438
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a consumption power force to be minimized and finally enable a fuel consumption of a vehicle to be improved by a method in which an electric oil pump installed at a vehicle is not controlled uniform irrespective of its quality, but it is studied in compliance with performance of the electric oil pump and can be controlled.SOLUTION: This invention comprises a condition determination stage for determining whether or not a studying condition for studying a requisite number of rotation in reference to quality of an electric oil pump is satisfied; a study waiting stage for controlling the electric oil pump to the number of rotation at a basic waiting state in response to the present oil temperature when the study condition is satisfied; a hydraulic pressure measuring stage for measuring the formed hydraulic pressure while controlling the electric oil pump to a prescribed study target number of rotation from the waiting state formed at the study waiting stage; and a map generating stage for forming a new study map by comparing the hydraulic pressure measured at the hydraulic pressure measuring stage with a hydraulic pressure of a prearranged reference map to form a new study map in such a way that it may be proportional to a difference between the measured hydraulic pressure and the hydraulic pressure in the reference map.SELECTED DRAWING: Figure 2
