1. A vehicle control apparatus comprising:
a controller configured to determine an estimated wheel speed value according to information related to at least one motor and information related to a plurality of wheel speed sensors,
wherein the controller is further configured to determine an air pressure state of a tire corresponding to each of the plurality of wheel speed sensors of a vehicle according to the estimated wheel speed value and the information related to the plurality of wheel speed sensors,
wherein the controller is further configured to:
estimate a wheel speed value of a defective wheel speed sensor using a wheel speed value of a wheel speed sensor among the plurality of wheel speed sensors in which a failure has not occurred based on that at least one wheel speed sensor among the plurality of wheel speed sensors fails,
determine a tire pressure using the estimated wheel speed value, and
inform a user of the air pressure state,
wherein the at least one motor includes at least one of a first motor connected to front wheels of the vehicle and a second motor connected to rear wheels of the vehicle,
wherein the plurality of wheel speed sensors include a first wheel speed sensor and a second wheel speed sensor engaged to the front wheels of the vehicle, and a third wheel speed sensor and a fourth wheel speed sensor engaged to the rear wheels of the vehicle, and
wherein the controller is further configured to determine a first estimated wheel speed value of the first wheel speed sensor and a second estimated wheel speed value of the second wheel speed sensor according to a number of revolutions per minute of the first motor, and assume the first estimated wheel speed value and the second estimated wheel speed value are the same based on that the first wheel speed sensor and the second wheel speed sensor fail.
