Abstract: In a hybrid vehicle, a hybrid type lubrication control valve which is a solenoid valve type turned on/off by electricity is used as a lubrication system component for circulating lubricating oil to a transmission and an engine clutch. A method for diagnosing sticking of a lubrication control valve of a hybrid vehicle includes measuring a drag torque acting on an input shaft of the transmission through an output shaft of the motor by measuring a first drag torque in an off-state of the independent type lubrication control valve and a second drag torque in an on-state thereof; and determining whether or not the independent type lubrication control valve is stuck, on the basis of a torque difference between the first drag torque and the second drag torque. The method can diagnose a stuck state of the hybrid type lubrication control valve using motor speed control, before starting the vehicle.

Abstract: A method and an apparatus for controlling a hybrid electric vehicle are provided. The method includes: determining whether a coasting condition is satisfied and whether a current gear stage is greater than or equal to a predetermined gear stage; determining whether a brake pedal is pushed when the coasting condition is satisfied and the current gear stage is greater than or equal to the predetermined gear stage; determining whether deceleration of the hybrid electric vehicle is less than a predetermined deceleration when the brake pedal is pushed; connecting a speed gear to an output shaft when the deceleration of the hybrid electric vehicle is less than the predetermined deceleration; determining whether a shift condition before stopping from a current gear stage to a target gear stage is satisfied; and locking up a shift clutch when the shift condition before stopping is satisfied.

Abstract: In a hybrid vehicle, a hybrid type lubrication control valve which is a solenoid valve type turned on/off by electricity is used as a lubrication system component for circulating lubricating oil to a transmission and an engine clutch. A method includes measuring, by an engine clutch pressure sensor, first engine clutch engagement pressure in an off-state of the independent type lubrication control valve and second engine clutch engagement pressure in an on-state thereof; and determining, by the TCU, whether or not the independent type lubrication control valve is stuck, on the basis of a pressure difference between the first engine clutch engagement pressure and the second engine clutch engagement pressure. The method can diagnose a stuck state of the hybrid type lubrication control valve using hydraulic pressure for operating engine clutch engagement, before starting the vehicle.

Abstract: A control method of a dual clutch transmission for a hybrid electric vehicle includes: determining, by a transmission controller, whether a vehicle has entered a power-off down-shift state; determining, by the transmission controller, whether a transmission including a first input shaft, a second input shaft, and an output shaft has entered a torque phase, when the first determining step determines that the vehicle has entered the power-off down-shift state; calculating a compensatory torque for compensating for a change in a regenerative braking force according to a change of a gear ratio in accordance with a completion percentage of the torque phase, when it is determined that a transmission has entered the torque phase; and compensating for regenerative torque of a motor by applying the compensatory torque.

Abstract: The present disclosure relates to a control method of a dual clutch transmission for a hybrid electric vehicle, and a control system for the dual clutch transmission. The control method includes: a handover step of performing a handover process of a transmission while controlling clutch torque of an engaging-side input shaft to maintain a rotational speed change rate of the engaging-side input shaft at a reference change rate; and an actual shifting step of synchronizing a rotational speed of a motor with a rotational speed of the engaging-side input shaft when the first finish determining step determines that the handover process has finished, and of increasing a rotational speed change rate of the motor by increasing motor torque when a synchronization rate is a reference synchronization rate or less.
