System for controlling a vehicle wheel tyre pressure

摘要: The invention concerns a system comprising control member (17) and, on each wheel, pressure sensor (12) and transmitter (13) for transmitting to the signal including data identifying sensor, means determining rotational speeds of wheels, associating (174-179), with corresponding wheel (12), which comprise (179) comparing concerning speeds, determined in different ways (34, 50), by time intervals (Ti) envelopes modulating signals transmitted transmitters antilock (20).
