The system comprises the following components: 1 TSS control unit 4 sets of wheel electronics including valve 1 digital antenna 4 trigger transmitters The wheel electronics mounted inside the tire measures tire pressure and temperature at regular intervals and transfers the values telemetrically via a HF transmission line to a reception antenna. The current pressure and temperature values can be requested specifically via the trigger function. In the receiver antenna, the radio data telegram is decoded and transferred to the control unit as a digital signal. The control unit evaluates the received data and forwards the information to the driver as required. This provides the driver with information on the nec- essary tire pressure or tire tension adjustments. The benefits offered by the tire pressure control system are: • Safety An early warning in case of fast pressure loss is given. "Blow-outs" caused by excessive flexing and driving too fast on inadequate tire pressure are avoided. The driver is prompted to adjust the tire pressure where necessary. • Comfort Tire handing is made simple. Using the filling equipment at the fuel station and removing the valve cap is only necessary for correcting the tire pressure. • New tire developments Tires with limp-home features avoid having to change a wheel immediately and render the spare wheel superfluous. They do, however, require permanent monitoring of the tire pressure. • Service life and economy Tire wear is minimized through correct air pressure. TSS 2. Generation BMW Tire Safety System TSS 2nd.

The measured data is sent from the wheel via a send stage in the wheel electronics. A system with relatively seldom measured data transfer is adequate for tire pressure monitoring provided it features the additional option of detecting sudden pressure loss. This enables the electronics in the wheel to be designed for minimum power draw and battery operation. All wheel electronics have their own code (ID) that is…
