摘要:
An engine clutch control system for a hybrid vehicle has a power source including an engine and a motor, an engine clutch between the engine and the motor, a traveling information detector that detects traveling information including at least one of the vehicle speed, shift gear, displacement of the accelerator pedal, and displacement of the brake pedal, and a hybrid controller that selects an EV mode or HEV mode by controlling disengagement or engagement of the engine clutch. A method of controlling the engine clutch includes determining whether there is a request for changing into the HEV mode from the EV mode; determining a reference speed from traveling inertia of the vehicle and inertia of the engine and the motor; determining a desired speed for controlling the determined reference speed; and calculating transmission torque of the engine clutch.

A system and method of controlling a fail-safe for a vehicle is provided. The method includes determining, by a controller, that remaining hydraulic pressure exists in the clutch when the clutch is not opened and a target value of oil pressure for opening the clutch is maintained for a predetermined time period. In addition, whether a vehicle is stopped is confirmed in response to determining that remaining hydraulic pressure exists in the engine clutch. The controller is further configured to transmit a signal to shift to the vehicle to a neutral (N) stage to a transmission controller and shift to the vehicle to the N-stage in response to determining that the vehicle is stopped. Then, the engine is driven by the controller in response to determining that the vehicle is shifted to the N-stage.

A method and system for controlling a low-voltage DC/DC converter (LDC) of a hybrid electric vehicle (HEV) includes performing a trial starting comprising steps of: trying ignition start, performing an immobilizer authentication process, and turning on a main relay of a high-voltage battery. The LDC is controlled after the trial starting, so that an operating voltage is applied from the LDC to an electric load including various kinds of controllers, thereby allowing starting of the HEV.

An electric vehicle and a cruise control method therefore are capable of improving ride comfort by reducing a pitch caused by a road surface deceleration factor. A method of controlling a smart cruise control function includes determining a target speed of a vehicle that is traveling when a road surface deceleration factor in front of the vehicle is detected, entering the road surface deceleration factor while traveling at a constant speed corresponding to the determined target speed, and performing pitch reduction control upon entering the road surface deceleration factor.

Disclosed herein are a method capable of controlling an engine clutch by estimating the speed of an electric motor in a situation where the speed of the motor is not measured, and a hybrid vehicle for performing the same. The method of controlling an engine clutch of a parallel-type hybrid vehicle includes determining whether a state of a transmission clutch and a predetermined state condition of an engine clutch are satisfied in a first controller, when an error occurs in motor RPM information sent from a second controller, replacing the motor RPM information with an input RPM of a transmission or an RPM of an engine, based on a result of the determination in the first controller, so as to send the same to a third controller, and controlling the engine clutch using the replaced motor RPM information in the third controller.

Disclosed are a hybrid electric vehicle, which may be effectively launched when an engine clutch to connect an engine and an electric motor for driving is fixed in a lock-up state, and a method of controlling the same. A method of controlling launch of a the hybrid electric vehicle provided with an engine clutch disposed between a first motor and an engine includes determining whether or not the engine clutch is in a lock-up state, securing running of the engine, upon determining that the engine clutch is in the lock-up state, executing slip launch of the hybrid electric vehicle using power of the engine, and launching the hybrid electric vehicle using power of the first motor, if first conditions by stall of the engine are satisfied. Execution of slip launch of the hybrid electric vehicle includes charging a main battery using a second motor connected to the engine.

A method for controlling a state of charge (SOC) of a battery for a cruise travel of a hybrid vehicle includes predicting, by a controller, the SOC of the battery including a change slope of the SOC of the battery for the cruise travel based on a measured value of the SOC. The method includes determining, by the controller, whether the predicted SOC of the battery is equal to or greater than a maximum value of a normal range of the battery when the change slope of the SOC is greater than zero. The method includes driving, by the controller, only a driving motor of the hybrid vehicle whereby the driving motor uses electric power of the battery when the predicted SOC of the battery reaches the maximum value of the normal range of the battery. The normal range of the battery is a region required for the cruise travel of the hybrid vehicle.
