Control apparatus of vehicle, and operating method of the same, vehicle

A method of operating of a vehicle control apparatus, the method comprising:

• acquiring, by a controller, information related to at least one motor in a vehicle;
• acquiring, by the controller, information related to a plurality of wheel speed sensors in the vehicle;
• determining, by the controller, an estimated wheel speed value according to the information related to the at least one motor and the information related to the plurality of wheel speed sensors;
• determining, by the controller, an air pressure state of a tire corresponding to each of the plurality of wheel speed sensors according to the estimated wheel speed value and the information related to the plurality of wheel speed sensors;
• and
• informing a user of the air pressure state,
• wherein the determining the estimated wheel speed value includes:
• estimating 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, and
• determining a tire pressure using the estimated wheel speed value,
• 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 in the determining of the estimated wheel speed value according to the information related to the at least one motor and the information related to the plurality of wheel speed sensors, 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.

A vehicle comprising:

• a plurality of wheels;
• a plurality of wheel speed sensors for measuring information related to the plurality of wheels;
