Acceleration control method through throttle dualization and vehicle using the same

A vehicle comprising:

• an electronic controller configured to detect an accelerator pedal scope (APS) by pressing of the accelerator pedal while the vehicle travels, to determine whether the APS is changed faster than a predetermined value, after determining an acceleration response improvement condition by an engine cold state, an engine speed, a target air amount, and a reference value for opening of a throttle valve, to determine a target throttle opening, a throttle delay time, an air regulator control speed, and a throttle angle filtering time constant according to a first throttle response mode using a target intake manifold pressure when the acceleration response improvement condition is satisfied or the APS is determined to be changed faster than the predetermined value, or to determine a target throttle opening, a throttle delay time, an air regulator control speed, and a throttle angle filtering time constant according to a second throttle response mode using a current intake manifold pressure when the acceleration response improvement condition is not satisfied or the APS is determined to not be changed faster than the predetermined value, and to perform acceleration control in the first throttle response mode or the second throttle response mode;
• and
• an engine system including the throttle valve which is controlled by the electronic controller and is provided in an intake manifold.
