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

A method for controlling a motor torque of a hybrid electric vehicle is provided. The method may include: detecting, with a controller, a downshift request during a regenerative braking; determining, with the controller, a target gear stage and a motor torque command, wherein the motor torque command is determined at a pre-shift stage before entering into a torque intervention; determining, with the controller, a motor torque command of the target gear stage; determining, with the controller, an intervention torque based on the motor torque command and the motor torque command of the target gear stage during a downshift control process; and controlling a torque intervention to control a regenerative operation of the motor based on the intervention torque, wherein determining the intervention torque includes changing the intervention torque from the motor torque command to a target value, which is set as the motor torque command of the target gear stage, during a shift control process.

Method for controlling a motor torque of a hybrid electric vehicle

A method for controlling a vehicle installed with an automatic transmission, includes: a sudden stop determination step in which a controller determines whether the vehicle has stopped at a speed greater than or equal to a reference deceleration speed and whether a post-stop elapsed time is within a first reference time; a takeoff determination step in which the controller determines whether an input torque of the transmission exceeds zero within the first reference time when a shift range is in a driving range; a pressure control step in which, when the vehicle takes off, the controller elevates a line pressure of the transmission; a limitation determination step in which if a slippage extent of a turbine exceeds a reference slippage value for a second reference time, the controller limits the takeoff; and a torque reduction step in which the controller reduces a takeoff torque input of the transmission.

Method for controlling vehicle equipped with automatic transmission

An apparatus and method of controlling a vehicle including a drive motor are provided. The apparatus includes a data detector that detects a driving information including a vehicle speed, a position value of a brake pedal and a drive motor speed and a drive motor that generates a driving torque for driving the vehicle and selectively operates as a generator. A controller then determines a braking mode based on the driving information and adjusts a shift completion timing in accordance with the braking mode.

Apparatus and method of controlling vehicle including driving motor

A system and a method of controlling a hybrid electric vehicle shift are disclosed. The system includes an engine and a drive motor operating as power sources and a transmission receiving driving torque from one of the engine and the drive motor. A data detector detects a state data for operating the transmission. A vehicle controller calculates a creep torque and an engine setting torque using the state data, determines whether a shift control condition is satisfied based on a position value of an accelerator pedal, calculates an available motor torque using a motor speed at an actual shift start point and a target motor speed when the shift control condition is satisfied, and calculates a first shift input torque using the creep torque, the engine setting torque, the available motor torque, and a first torque apply ratio. The transmission is operated based on the first shift input torque.
