Abstract
This is a multi-functional warning system for a vehicle and the related control method. This system is composed of a host unit and branch units. The branch unit is deposed in a tire, which includes sensor(s) for monitoring the pressure, temperature or other information about the tire; if it detected a tire in deflated high temperature or loosed status, it would generate a RF signal that would be sent to the host unit. The hosts unit deals with not only aforesaid RF signals, but also signals from acceleration sensor and signals about high-water-temp, low-oil pressure etc., a CPU processes all information and then gives a corresponding indication in voice, digital and light to warn the driver. Upon severe tire failure or high deceleration of the vehicle, the host unit send out a warning signal, make a warning light flicker to provide the follow-on vehicle with a warning, in bad weather it can turn on the warning light to guide and prevent rear-end collision. The system has advantage of giving an intelligent warning for tires, devices in the vehicle, and the trouble like high deceleration, which secure the safety of the personnel and the vehicle.
