Title:
DATA BUS SYSTEM FOR POWER VEHICLE
Document Type and Number:
Japanese Patent JP3950545
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the data bus system where a zero input current is sufficiently reduced regardless of availability of required functions when an ignition device is inactive.
SOLUTION: In the data bus system for a power vehicle, a bus subscriber 1(2, 3, 4) is provided with evaluation circuits 7, 10, 11 (evaluation circuit 5) and with a controllable switch 6. In a base state, power supply to the respective bus subscribers except for the evaluation circuit(s) is interrupted by the opened switch 6 when an ignition device is switched off. In a selective starting state, the evaluation circuits close the controllable switches 6 of selected bus subscribers for temporarily required data exchanges C1, C2, C3, C4 between the selected bus subscribers, and for the control of the starting state, at least one of the bus subscribers is defined as a main bus subscriber 1.
