Car component state real-time processing method

The invention provides a car component state real-time processing method. The method comprises the steps that a standard impulse count is obtained through an original car wheel impulse count and a corresponding correction coefficient; an error between the standard impulse count and an actual impulse count is computed, and a rotation angle error is obtained; a rotation angle mean value and a relative error of a tire are computed, and whether the tire pressure is abnormal or not is judged according to the relative error; alarming thresholds of different car speed intervals are determined; and the gas leakage state of the tire is judged according to a sampling value of car wheel rotation speed data. According to the car component state real-time processing method, the operation processing can be conducted just through existing sensor elements, the tire pressure is effectively and dynamically monitored in the running process, the hardware cost is reduced, and the operation accuracy is improved.
