Introduction
The TPMS ECU will serve as the interface between TPMS Transmitters and the CAN
communications bus within the Vehicle.
The TPMS ECU will receive RF transmissions from the Transmitters.
It will decode and analyse these transmissions and provide data on the tyre pressure
and temperature and location for each wheel on the vehicle.
Based on the data from the Transmitters and an algorithm developed, the TPMS
ECU will report warnings and tyre pressures over the CAN bus.
The TPMS ECU will be installed in a position on the vehicle to be agreed between
Schrader and the Customer. The TPMS ECU location is key to its correct operation.
It is expected that the CAN interface will be fixed and that different displays can be
supported without any update to the Schrader TPMS ECU.
The receiver ECU shall decode the incoming RF signals, format the data, and
transfer the data to the CAN bus within the vehicle as required by the customer or
supplier. The system shall also automatically detect the wheel locations of each
transmitter on the vehicle.
Environmental compatibility requirements
The TPMS ECU shall operate without degradation over the temperature range -40°C
to +105°C. All components of the TPMS ECU shall be rated to a temperature range
which covers -40o C to +105o C.
The TPMS ECU Enclosure is resilient against the environment in which it is to be
placed.
The TPMS ECU complies with ETSI (RTTE governed), FCC (USA) and IC (Canada)
regulatory requirements.
