A method and device for controlling a running mode of a hybrid vehicle are provided. The method includes monitoring power consumption of a battery when the hybrid vehicle is driven in an electric vehicle (EV) mode and calculating a threshold value for starting an engine. Then, whether to change the running mode of the hybrid vehicle is determined using the power consumption of the battery and the threshold value for starting the engine.

Device and method for controlling running mode of hybrid electric vehicle

A method for learning an engine clutch kiss point of a hybrid vehicle includes: controlling, by a controller, an engine clutch which connects an engine with a motor or disconnects the engine from the motor so that the engine clutch is engaged after the controller checks stop of the engine and of the motor and stabilization operation for a hydraulic pressure line of the engine clutch is performed; controlling the motor to have a certain speed after the stabilization operation; controlling the engine clutch to be engaged after speed of the motor is stabilized; determining whether torque variation of the motor when the engine clutch is engaged is equal to or greater than a threshold value; and determining a hydraulic pressure at which the torque variation is the threshold value as the kiss point of the engine clutch.

An apparatus and a method for controlling a clutch slip of a hybrid vehicle enable slipping even in a dry engine clutch having a small heat capacity by simultaneously slipping an engine clutch and a dual clutch in a hybrid vehicle mounted with a dual clutch transmission (DCT) to disperse the heat capacity. The apparatus for controlling the clutch slip of a hybrid vehicle includes: an engine clutch selectively connecting an engine and a motor generating power; a dual clutch mechanism selectively connecting the motor and a transmission; and a controller controlling an operation of the engine clutch and two clutches of the dual clutch mechanism, in which the controller may simultaneously perform a dual clutch slip control according to a motor speed and an engine clutch slip control according to an engine speed.

The present disclosure provides a system and a method of controlling motor vehicle operation. The method may include: setting a creep torque as a minimum torque; setting a maximum torque as a sum of a maximum torque of an engine and a maximum torque of a motor; monitoring an acceleration pedal position sensor (APS) value; calculating a demand torque according to the APS value; setting a filter coefficient for filtering the demand torque according to an operating condition of the vehicle; and filtering the demand torque by means of the filter coefficient.

System and method of controlling motor vehicle operation

Disclosed is a method and power delivery system for controlling creep torque in a hybrid or electric vehicle. More specifically, a brake signal is detected and a creep torque output is controlled based on the brake signal. The creep torque is outputted for a predetermined time from a point when a brake on signal is first generated. Accordingly, a creep torque is generated for a predetermined time when a brake is being operated and backlash is eliminated between gears so as to prevent a backlash shock from the gears when the brake is released. Additionally, the vehicle may be propelled forward or backward by the creep torque in the creep torque control method of a vehicle according to an exemplary embodiment of the present invention.
