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.

A system for controlling a lock-up of engine clutch may include an engine and a motor; the engine clutch mounted between the engine and the motor and configured to selectively transmit power of the engine between the engine and the motor; a hybrid starter generator (HSG) connected to a crank pulley of the engine and driven to start the engine; and a controller connected to the HSG and configured to determine a virtual engine speed in an engine firing process and a torque reduction ratio of the HSG according to the virtual engine speed after an engine cranking process and determine a correction reduction ratio with respect to the torque reduction ratio of the HSG using a difference value between the virtual engine speed and an actual engine speed, and adjust an increase or a decrease of the torque reduction ratio of the HSG to synchronize an engine speed with a motor speed for the lock-up of the engine clutch.

A motor torque control apparatus for a hybrid vehicle includes: a calculator for calculating a model speed of a motor, a control model speed, an anti-jerk torque, and an anti-jerk torque control factor; and a controller for controlling the calculator. At the time of LFU shifting, the controller controls a motor speed using the anti-jerk torque, determines whether the motor speed controlled using the anti-jerk torque is abnormal based on the maximum difference value between the motor speed and the model speed and a reduction in the motor speed, corrects the anti-jerk torque based on the control model speed and the anti-jerk torque control factor upon determining that the motor speed is abnormal, and controls the motor speed using the corrected anti-jerk torque.

An apparatus and a method for controlling a driving mode of a vehicle are provided. The apparatus includes a mode converter that converts the driving mode of the vehicle based on an operation of a mode conversion input. When the driving mode is converted into a custom mode, a mode setting screen for adjusting a setting value of a driving characteristic preset is configured and the configured mode setting screen is displayed on a display of the vehicle. A tuning device then tunes a driving characteristic of the custom mode based on a setting value adjusted on the mode setting screen.

Apparatus and method for controlling driving mode of vehicle

An anti-jerk control system and method of an eco-friendly vehicle are provided to prevent a driver from sensing a difference in vehicle starting at an initial stage when the vehicle is parked on a downhill road. The anti-jerk control method uses a motor as a driving source and includes calculating an actual speed of the motor, calculating a model speed of the motor, and acquiring a gradient of a road, on which the vehicle is located, using a gradient detector. Additionally, the method includes determining a speed offset value that corresponds to the acquired gradient, compensating the model speed by the speed offset value, and calculating a motor vibration component using a difference between the compensated model speed and the actual speed of the motor. Then, anti-jerk compensation torque is calculated using the calculated motor vibration component.
