Title:
CONTROL METHOD AND CONTROL SYSTEM FOR HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2023162776
Kind Code:
A
Abstract:
To appropriately perform hydraulic control through learning on the basis of actual hydraulic pressure detected by a hydraulic sensor when performing the hydraulic control for shifting a friction fastening element from a release state to a fastening state.SOLUTION: In a hybrid vehicle 1, when performing hydraulic control for shifting a first clutch CL1 (friction fastening element) from a release state to a fastening state, a controller 20 determines an estimation hydraulic pressure applied to the first clutch, determines estimation timing at which the shift from the release state to the fastening state is started in the first clutch on the basis of the estimation hydraulic pressure, determines a dispersion value of an actual hydraulic pressure detected by a hydraulic sensor SN4, determines actual timing at which the shift from the release state to the fastening state in the first clutch is started on the basis of the dispersion value, and performs learning for correcting the hydraulic pressure to be applied to the first clutch during the hydraulic control on the basis of a difference between the estimation timing and the actual timing.SELECTED DRAWING: Figure 5
