AUTOMATIC INDUSTRIAL STATION

FOR VEHICLES EQUIPPED WITH INTELLIGENT VALVES

30/09/03

Training course

Siemens Schrader (GB)

Each valve contains:

A receptionantenna

+ A transmitting antenna

Training course

- Schrader (GB) - Siemens, Beru (Germany)- TRW (USA)- Pacific valve (Asia)- Johnson control (SAGEM)

Details on the valves available:

- Up until mid-2003: after having been awoken, the valve transmits its identifier and the pressure of the tyre.

- Next evolution: depending on a specific set of data which it will receive, each valve will be programmable (the valves will have several modes of operation: for example, it will be possible to return the valves to a sleep mode (to extend battery life), they will allow the access to other technical information

Battery autonomy, valve production date, humidity, acceleration, temperature….

Note: as a general rule, to operate, the valve must be pressurised ( > 500 mbar)

Training course

• Each valve has its own unique identifier code=> the driver knows which tyre is concerned with an

eventual low pressure problem.

• This identifier code is also used to avoid an interference between two 2 cars stationed next to each other.

• Installed on the production line, the station transmits each identifier code to the vehicle computer through the factory network.

Without that, the vehicle dashboard would display and “error”, as no valve would be recognized by the vehicle computer.

Training course

• Activation frequency: 125 KHz.

Range: adjustable from 20 cm to 1 m.

Cycle time: generally 50 sec. *

Field of emissions: about 250 A/m.

AM/FM reception: 433 and/or 315 MHz (1 single installation = two frequencies)

Production line speed: up to 6m/min*

SSPP Station:Technical data Antennas/Network

*depending on the valve type
