System description

The Tire Safety System (TSS) controls and monitors tire pressures.

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

necessary 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.
