Document Type and Number:
Japanese Patent JP4497077
Kind Code:
B2
Abstract:
A vehicle alternator failure monitoring system and related monitoring method are disclosed wherein an ECU executes operations depending on a power generation status of a vehicle alternator and a vehicle alternator control device has a serial communication transmitter circuit operative to transmit a serial communication signal, indicative of the power generation status of the vehicle alternator, to the ECU. The serial communication transmitter circuit has a first power generation status signal transmission mode in which a first power generation status signal, representing the power generation status, is transmitted together with a failure flag representing the presence of or absence of an operational failure, related to the vehicle alternator, and a second power generation status signal transmission mode in which a second power generation status signal, representing the power generation status, is transmitted together with additional data representing an operational state of the vehicle alternator.
