System for monitoring tyre pressure in vehicles

摘要

The system has a tire pressure monitoring device (1) for transmitting a data packet that comprises a set of data telegrams. A determination is made to check whether a roll sensor (1b) detects a turning of a wheel, where process of transmission of the data packet is interrupted when the roll sensor does not detect the turning of the wheel. The process of transmitting the data packet is continued when the roll sensor is re-activated within a pre-defined time span. The tire pressure monitoring device switches to a normal mode of operation after complete transmission of the data packet. An independent claim is also included for a method for controlling transmission operation of a tire pressure monitoring device.
