ERRONEOUS CLUTCH FASTENING DETERMINATION DEVICE, AND CONTROL DEVICE FOR COPING WITH ERRONEOUS CLUTCH FASTENING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To quickly determine erroneous clutch fastening in a vehicle in which a continuously variable transmission connected to an electric motor through a clutch is operated by hydraulic pressure of an electric motor-driven oil pump.SOLUTION: An erroneous clutch fastening determination device of a vehicle including an electric motor 2 as a vehicle driving source, an oil pump 50 connected to the electric motor 2, a continuously variable transmission 3 using hydraulic pressure from the oil pump 50, a clutch 7 interposed between the electric motor 2 and the continuously variable transmission 3, and vehicle control means 10 for controlling the clutch 7 for complete engagement, slip engagement, or release, and controlling the electric motor 2 so as to rotate at a target rotation speed which is a lower limit rotation speed or more, includes temporary abnormality determination means 32 for determining whether or not a condition that there is no input/output rotational speed difference in the clutch 7 (temporary abnormality determination condition) has been established when a permission condition is established, and abnormality finalization means 33 that when the temporary abnormality determination condition has been established, determines whether or not a condition that the rotation speed of the electric motor 2 is lower than the lower limit rotation speed (abnormality finalization condition) has been established, and finalizes an erroneous fastening state of the clutch 7.SELECTED DRAWING: Figure 1
