METHOD AND DEVICE FOR COMMUNICATION OF A VOLTAGE REGULATOR OF A MOTOR VEHICLE ALTERNATOR ON AN ON-BOARD NETWORK, AND CORRESPONDING VOLTAGE REGULATOR AND ALTERNATOR
A communication method and device of a voltage regulator of a motor vehicle alternator on an onboard network, and corresponding voltage regulator and alternator. The communication method according to the invention, for a voltage regulator (36) of a motor vehicle alternator on an onboard network of the vehicle, consists of exchanging information frames on a serial bus (43) according to one or more different proprietary protocols compatible with a standardised protocol. According to the invention, the information frames are encoded or decoded depending on controls and statuses of a standard voltage regulator having predefined characteristics, and the method comprises steps of reading or writing the information frame fields depending on the predefined locations and lengths of same, converting the field values by means of a linear interpolation (39), and addressing the control and status registers (35) of the standard voltage regulator based on predefined parameters.
