Method and device for determining a tire wear amount

A device for determining a tire wear amount for a vehicle, the device comprising:

• a wheel speed sensor configured to measure a rotational speed of each wheel of a plurality of wheels of the vehicle that is traveling;
• a seat sensor configured to detect whether each seat of a plurality of seats in the vehicle is occupied;
• a yaw rate sensor configured to measure a yaw rate of the vehicle, the yaw rate being a criterion for determining stability of the vehicle;
• a memory configured to store tire characteristic information of various types of tires;
• a controller configured to determine a longitudinal friction force and a lateral friction force acting on the vehicle using data provided by the wheel speed sensor, the seat sensor, and the yaw rate sensor, and determine a tire wear amount based on the tire characteristic information;
• and
• a display unit configured to display information based on the tire wear amount.
