Vehicle and vehicle control method

A vehicle, comprising:

• a speed detector for detecting a driving speed of the vehicle;
• a sensor for detecting a target vehicle driving in a target lane into which the vehicle is to change from a driving lane of the vehicle;
• and
• a controller for determining an acceleration of the vehicle based on a change amount of the driving speed detected at the time of the vehicle entering the target lane, for calculating a time to collision (TTC) between the vehicle and the target vehicle based on the acceleration of the vehicle when the vehicle enters the target lane, and for transmitting a signal for restricting a lane change of the vehicle based on the TTC,
• wherein the sensor detects a first target vehicle driving in the target lane in front of the vehicle, and detects a second target vehicle driving in the target lane behind the vehicle,
• wherein the controller does not transmit the signal for restricting the lane change if the acceleration of the vehicle is less than a reference value when the vehicle enters the target lane behind the first target vehicle, and
• wherein the controller does not transmit the signal for restricting the lane change if the acceleration of the vehicle exceeds the reference value when the vehicle enters the target lane in front of the second target vehicle.
