Communication method between a plurality of electronic measurement modules of a motor vehicle
First Claim
1. A method for communicating measurement messages between a plurality of electronic measurement systems and an electronic controller of a motor vehicle, each of the electronic measurement systems being mounted in a wheel of said vehicle, said method comprising:
- measuring, by at least one first electronic measurement system of the electronic measurement systems that is a primary emitter system, parameter values associated with the wheel in which said primary emitter system is mounted;
sending, by said primary emitter system, over a first radio communication link at a power below a first threshold, measurement messages to at least one second electronic measurement system, of the electronic measurement systems, that is mounted in the wheel of the vehicle, the second electronic measurement system being a relay system;
receiving, by said relay system the measurement messages sent over the first radio communication link;
measuring, by the relay system, parameter values associated with the wheel in which said relay system is mounted to obtain its own measurements; and
sending, by the relay system, the measurement messages received and the measurements obtained by the relay system to the electronic controller over a second radio communication link at a power above a second threshold, higher than or equal to the first threshold.

Abstract
Disclosed is a method for communicating measurement messages between a plurality of electronic measurement modules and an electronic control unit of a motor vehicle. The method includes the steps of measurement (E1), by a primary emitter module, of parameter values associated with the wheel in which the module is mounted, of sending (E2), by the primary emitter module, of measurement messages to a relay module, of reception (E3) by the relay module, of the measurement messages sent, of measurement (E5), by the relay module, of parameter values associated with the wheel in which the relay module is mounted and of sending (E6), by the relay module, of the measurement messages received and of its own measurements to the electronic control unit.

15. A communication system for a motor vehicle comprising:
-
an electronic controller; and a plurality of electronic measurement systems each mounted in a wheel of said vehicle, said plurality of electronic measurement systems comprising at least one first electronic measurement system that is a primary emitter system and at least one second electronic measurement system that is a relay system, said primary emitter system being configured to measure parameter values associated with the wheel in which said primary emitter system is mounted and to emit, to said relay system, over a first radio communication link at a power below a first threshold, signals comprising measurement messages, the relay system being configured to receive signals emitted by the primary emitter system, to measure parameter values associated with the wheel in which said relay system is mounted to obtain its own measurements, and to emit signals comprising the measurement messages received and the measurements obtained by the relay system to the electronic controller over a second radio communication link at a power above a second threshold, higher than or equal to the first threshold. - View Dependent Claims (16, 17, 18, 19, 20)
