Method and apparatus (200) for monitoring vehicle tire pressure and warning the driver when a low tire inflation pressure condition occurs includes transponder tags (220a . . . 220d, 300, 300a) and associated sensors (e.g., pressure, temperature) for each tire and a monitor (230a . . . 230d, 400 disposed in close proximity to each tire (204a . . . 204d). In this case manner, a low-powered radio transmission can take place between each tire tag and an associated one of the monitors. Each monitor is connected to a vehicle data bus 206, 430) for communicating, preferably bi-directionally, with a computer (208), and a central display (212) provides visual (or audible) warnings to the operator of the vehicle. The system is simple in operation, economical to manufacture, easy to install, and highly reliable, and conforms to standards established for heavy vehicles, and can be used on passenger car applications as well.
In a vehicle having pneumatic tires, a system for monitoring tire pressure comprising an RF tag associated with each of the vehicle tires, each tag providing a signal indicative of respective tire pressure;
A method of monitoring vehicle tire pressure wherein the RF tag is associated with each of the vehicle tires, each tag providing a signal indicative of respective tire pressure;
