Historical Development of Tire Pressure Monitoring System

As early as 200 1, the United States passed the TRAD Act, requiring all new cars sold in the United States to come standard with TPMS by 2007. In 2002, the National Highway Traffic Safety Administration (NHTSA) issued regulations requiring that when the tire pressure is lower than 25%~30% recommended by the manufacturer, the monitor will give an alarm to the driver, and it is suggested that the tire pressure monitoring system (TPMS) should be installed on new cars from 2004. After the United States, Europe has also enacted corresponding regulations, requiring its domestic automobile manufacturers to install TPMS.

At the Indianapolis Expo in 2004, Smar Tire Equipment Company of Canada introduced the second set of motorcycle tires TPMS in the world. The first set was introduced by British Meta Systems Company in 2002. This product can monitor and display the inflation pressure and temperature information of each tire during motorcycle running. If there is any deviation, the rider will be reminded by the warning light.

The battery-free tire pressure monitoring system developed by Alpine Electric Company in Japan has recently passed relevant tests, which conforms to the relevant regulations of electromagnetic waves in Europe and America. In the future, the evaluation will focus on the influence of driving conditions and tire types, and field tests are planned in Europe, America and Japan. Samples will be provided in August 2004 and put into mass production in 2006.
