VEHICLE CONTROL DEVICE

A vehicle control device includes a sensor configured to sense driving information of a vehicle, and a controller. The controller is configured to activate or deactivate a fuel conservation mode of the vehicle based on a user input, and restrict acceleration of an engine of the vehicle to be within a predetermined range based on an accelerator pedal of the vehicle being pressed with a force that is greater than a threshold force and based on the vehicle being in an activated state of the fuel conservation mode. The controller is also configured to, based on the driving information satisfying a first condition, release a restriction on the acceleration of the engine of the vehicle in the activated state of the fuel-conservation mode.
