DOUBLE OPEN CAN BUS WIRE FAULT IDENTIFICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18063147 titled 'DOUBLE OPEN CAN BUS WIRE FAULT IDENTIFICATION

Simplified Explanation

The patent application describes a method for detecting a two-wire open fault on a two-wire communications bus by analyzing data from electronic control units and generating an error report if the network health indicator exceeds a threshold.

• The method involves analyzing data from multiple electronic control units on a two-wire communications bus.
• It determines a threshold based on the data received from the control units.
• A current network health indicator is calculated based on the data received from the control units.
• If the network health indicator exceeds the threshold, a double wire open fault error report is generated.
