An embodiment acceleration limit control method includes determining an acceleration limit based on information on a passenger, determining a disturbance torque due to a disturbance, other than a drive source of a vehicle, based on at least a slope, determining a torque limit satisfying the acceleration limit based on the disturbance torque, and determining an output torque to be generated by the drive source based on the torque limit and a driver's requested torque.

Vehicle and acceleration limit control method therefor

A method for providing engine start information for a hybrid electric vehicle includes determining a likelihood of engine start for each of a plurality of reasons for engine start, and displaying a reason for engine start having a highest likelihood of engine start from among the plurality of reasons for engine start and engine start information including the highest likelihood of engine start in consideration of a type of at least one reason for engine start and a level of the likelihood of engine start.

Hybrid electric vehicle and engine start information display method therefor

A vehicle includes: a plurality of wheels; a motor for providing a driving force to the plurality of wheels based on electrical energy stored in a battery; a modulator for controlling a number of rotations of the motor; and a controller for controlling the modulator based on a first control value at a coasting control and controlling the modulator based on a second control value when a wheel slip occurs in a safety control.

Vehicle and control method thereof

A method of controlling reverse driving of a hybrid vehicle is provided, in which a reverse gear train of a gear box of a transmission for reverse driving is omitted. When a gear stage enters a reverse stage or is changed from a drive stage to a reverse stage, an engine performs an electric energy charging function on a battery via a hybrid starter generator and a motor transmits driving power for reverse driving to travelling wheels. Accordingly, the battery is charged with electric energy and simultaneously, the motor is reversely driven based on the electric energy supplied from the battery, thereby enabling a hybrid vehicle to be more easily reversed.

System and method of controlling reverse driving of hybrid vehicle

A device for controlling an engine clutch in an environmentally-friendly vehicle, wherein the engine clutch is disposed between an engine and a driving motor and is configured to selectively connect the engine to the driving motor, includes: a transmission configured to receive a driving force that is transmitted from at least one of the engine and the driving motor by release or engagement of the engine clutch; and a controller configured to control the engine clutch based on a gear of the transmission when the failure of the engine clutch is detected and configured to charge a battery using the engine.

Device and method for controlling an engine clutch in an environmentally-friendly vehicle

A method for releasing creep torque control of a vehicle before a stop includes a step of when creep torque is controlled for a shift before a stop of the vehicle, creep torque control is released in consideration of a current shift gear position if an actual creep torque value controlled during a shift becomes equal to a target creep torque value.

Method for releasing creep torque control of vehicle before stop

A method for learning a touch point of an engine clutch of a hybrid electric vehicle including a motor connected to a transmission and an engine selectively connected to the motor through the engine clutch includes determining whether a learning condition of the touch point of the engine clutch is satisfied, releasing a transmission clutch and controlling a motor speed when the learning condition is satisfied, increasing a coupling pressure of the engine clutch when a change amount of the motor speed is less than a first predetermined value, comparing a change amount of a motor torque according to the increased coupling pressure of the engine clutch with a second predetermined value, and learning the touch point of the engine clutch when the change amount of the motor torque is greater than or equal to the second predetermined value.

A method for determining a connection state of an engine clutch includes: a stroke sensing operation of sensing, by a controller, a change of an actuator stroke of the engine clutch; a first pressure comparing operation of determining whether or not an actuator pressure of the engine clutch exceeds a first set pressure and is then changed to below the first set pressure when the actuator stroke is increased; a torque comparing operation of comparing transfer a torque of the engine clutch with a set torque when the actuator pressure exceeds the first set pressure and is then operated to below the first set pressure; and an open determining operation of determining that the engine clutch is in an open state when the transfer torque of the engine clutch is the set torque or less.

Method for determining connection state of engine clutch

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.

Method for learning engine clutch kiss point of hybrid vehicle

A method for learning a touch point of an engine clutch for a hybrid electric vehicle includes controlling a speed of an engine to have an idle speed. A fluid pipe of a clutch actuator is refilled with a working fluid by driving a driving motor in an idle control state of the engine, a speed of the driving motor is synchronized with the speed of the engine, and then the engine clutch is engaged. The engine clutch is released after the refill is performed, and the speed of the driving motor is decreased. A working fluid is applied so that the engine clutch is operated in an engagement direction by operating the clutch actuator, and a state change of the driving motor is detected. The touch point of the engine clutch is determined based on the state change of the driving motor.
