Abstract
Official abstract text for this publication.
Disclosed is a detecting method of engine clutch delivery torque of a vehicle including: determining, by a controller, when the position of a shift lever satisfies a detecting condition of engine clutch delivery torque; converging, by the controller, to a predetermined target speed by operating a motor without load; measuring, by the controller, motor torque without a load at the target speed and engaging the engine clutch with a control pressure above a contact point (contact point+α) according to a control logic; detecting, by the controller, motor torque including the delivery torque of the engine clutch, when the speed and the torque of the motor converge according to engagement of the engine clutch; calculating, by the controller, torque deviation by comparing the motor torque without load and the motor torque including the engine clutch delivery torque; and detecting, by the controller, a compensation factor by comparing a model value of the engine clutch delivery torque with the torque deviation.
First claim
Opening claim text (preview).
What is claimed is: 1. A detecting system for engine clutch delivery torque of a vehicle equipped with an engine and a motor as power sources, the system comprising: an engine clutch configured to implement an EV (electric vehicle) mode and an HEV (hybrid electric vehicle) mode by engaging and disengaging the engine with the motor; an inverter configured to operate the motor by a hybrid controller; a transmission sensor configured to detect the status of a transmission; and…
