Abstract

A tire pressure monitoring device includes a pressure measurement sensor provided on each of the wheels to be monitored, a transmitter arranged near each pressure measurement sensor for sending signals representative of the pressure determined by the pressure measurement sensor, respective antennas for receiving the signals, the antennas being arranged on the vehicle chassis near the respective wheel. Each antenna is formed by making use of a separate electric line belonging to another monitoring system that is associated to the same wheel or is formed by making use of a sensor belonging to another monitoring system associated to the same wheels. Alternatively an electric line that leads to another consumer which is associated to the respective wheel, like a lamp, is used as an antenna.
