ENGINE CLUTCH TRANSMISSION TORQUE LEARNING APPARATUS AND METHOD OF ENVIRONMENT FRIENDLY VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an environment friendly vehicle that learns transmission torque by the characteristics deviation of components related to an engine clutch control and can improve operability, start responsiveness, and fuel consumption.SOLUTION: An environment friendly vehicle has: an engine clutch that achieves an EV mode or an HEV mode by coupling or releasing an engine or a motor; an inverter that drives the motor by controlling a hybrid controller; a transmission shift lever detector; a hybrid controller. If a transmission state is an engine clutch transmission torque learning condition, the hybrid controller maintains between an engine and a motor in no-load-condition at a constant relative velocity by driving the motor at a target speed, couples engine clutches by the control pressure (kiss point pressure + ) that exceeds the kiss point, measures the motor torque including the transmission torque of the engine clutch, and learns the transmission torque of the engine clutch by the difference with the basic model value.
