Abstract

A tire pressure monitoring system includes a resolver for detecting a motor speed generating driving torque. A wheel speed sensor detects a wheel speed of wheels rotated by the driving torque generated at the motor. A transmission decelerates the driving torque generated at the motor. A controller is configured to compare a first target wheel speed calculated using the motor speed detected by the resolver to the wheel speed sensor detected by the wheel speed sensor and determining a status of a tire, when a wheel slip ratio is less than a predetermined value.

Description

[0001] Cross references to related applications [0002] This application claims the right of priority for Korean Patent Application No. 10-2014-0067186 filed to the Korean Intellectual Property Office on June 2, 2014, and the entire content of the application is incorporated herein by reference. Technical field [0003] The present disclosure relates to a tire pressure monitoring system and a tire pressure monitoring method of a motor-driven vehicle. More specifically, the present disclosure relates to a tire pressure monitoring system of a motor-driven vehicle and a tire pressure monitoring method that indirectly monitors the tire pressure. Background technique [0004] If the tire pressure of the vehicle is too high or too low, the tire may crack, or the vehicle may slip easily, which may cause a major accident. In addition, the fuel consumption of the vehicle becomes high, thereby reducing fuel efficiency. In addition, the life limit of tires becomes shorter, and the comfort a...
