Abstract
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.

Claim 1
Independent Claim
106 words
A device fitted to vehicles equipped with a chassis and wheels having pneumatic tires, said device for monitoring the air pressure within said tires, comprising: a respective pressure measurement sensor provided on each of the wheels to be monitored; a respective transmitter arranged near each pressure measurement sensor for sending signals representative of the air pressure determined by the pressure measurement sensor; a receiver for receiving the pressure signals, said receiver arranged on the chassis of the vehicle neighboring the respective wheel; an antenna arranged near each wheel, said antenna comprised of an electric line belonging to another monitoring system associated to each of the wheels.
Claim 2
Independent Claim
106 words
A device fitted to vehicles equipped with a chassis and wheels having pneumatic tires, said device for monitoring the air pressure within said tires, comprising: a respective pressure measurement sensor provided on each of the wheels to be monitored; a respective transmitter arranged near each pressure measurement sensor for sending signals representative of the air pressure determined by the pressure measurement sensor; a receiver for receiving the pressure signals, said receiver arranged on the chassis of the vehicle neighboring the respective wheel; an antenna arranged near each wheel, said antenna comprised of an electric line belonging to another monitoring system associated to each of the wheels.
Claim 3
Dependent Claim
79 words
the device of claim 1 , wherein: 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 tire pressure determined by the pressure measurement sensor, a receiver for the signals arranged on the chassis of the vehicle neighboring the respective wheel, wherein each receiver uses a sensor belonging to another monitoring system associated to each of the wheels for its respective antenna.
