Intelligent intervention method based on integrated TPMS
First Claim
1. An intelligent intervention method based on an integrated tire pressure monitoring system (TPMS) having a direct TPMS and an indirect TPMS, the method comprising:
- monitoring, by the direct TPMS, a tire pressure and a tire temperature of a vehicle, and monitoring, by the indirect TPMS, a wheel speed of the vehicle;
transmitting the tire pressure, the tire temperature and the wheel speed to a host;
judging in real time, by the host, whether the vehicle is in a normal status or in an abnormal status, via integrating the tire pressure, the tire temperature and the wheel speed;
producing, by the host, a deviation signal, when the tire pressure, the tire temperature and the wheel speed deviate from normal thresholds and transmitting the deviation signal to an intelligent intervention system; and
performing, by the intelligent intervention system, intelligent intervention to slow down the vehicle in a straight line until the vehicle stops, when the deviation signal is received.

Abstract
An intelligent intervention method based on an integrated tire pressure monitoring system includes monitoring a tire pressure and a tire temperature of a vehicle, and monitoring, a wheel speed of the vehicle; transmitting the tire pressure, the tire temperature and the wheel speed to a host; judging in real time whether the vehicle is in a normal status or in an abnormal status, via integrating the tire pressure, the tire temperature and the wheel speed; producing a deviation signal, when the tire pressure, the tire temperature and the wheel speed deviate from normal thresholds and transmitting the deviation signal to an intelligent intervention system; and performing intelligent intervention to slow down the vehicle in a straight line until the vehicle stops, when the deviation signal is received. The method enables the vehicle to run safely until stopping even in case of tire blowout, so as to prevent rollover or collision.

9. An intelligent intervention apparatus comprising:
-
an intelligent intervention system that performs intelligent intervention for a vehicle; an integrated tire pressure monitoring system (TPMS) comprising; a direct TPMS that monitors a tire pressure and a tire temperature of the vehicle; and an indirect TPMS that monitors a wheel speed of the vehicle; a host coupled with the integrated TPMS and configured to receive the tire pressure, the tire temperature and the wheel speed; judge in real time whether the vehicle is in a normal status or in an abnormal status via integrating the tire pressure, the tire temperature and the wheel speed; produce a deviation signal when the tire pressure, the temperature and the wheel speed deviate from normal thresholds; and transmit the deviation signal to the intelligent intervention system; wherein the intelligent intervention system performs the intelligent intervention to slow down the vehicle in a straight line until the vehicle stops, when the deviation signal is received. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
