1. A vehicle, comprising:
a headlamp configured to irradiate light forward;
a plurality of suspensions including front suspensions and rear suspensions, each front suspension being coupled to a corresponding front wheel of a vehicle and each rear suspension being coupled to a corresponding rear wheel of the vehicle;
a plurality of suspension sensors configured to detect a height of each of the plurality of suspensions, respectively;
a plurality of tire sensors configured to detect a height of each tire of the vehicle, respectively; and
a controller electrically connected to the headlamp, the plurality of suspensions, the plurality of suspension sensors, and the plurality of tire sensors;
wherein the controller is configured to:
receive a height value of each suspension of the plurality of suspensions from a corresponding suspension sensor of the plurality of suspension sensors,
receive a height value of each of the tires from the plurality of tire sensors,
determine height change values of front tires by comparing a maximum height value among the height values of the front tires with a predetermined reference height of the front tires, and
adjust a light irradiation angle of the headlamp by using the first difference value with respect to the front suspensions and the height change values of the front tires.
