Abstract
An error recovery method performed in an end node of an Ethernet-based vehicle network includes: detecting, by a physical (PHY) layer processor of a PHY layer of the end node, a physical error of a message, when the message is received at the PHY layer of the end node; detecting, by a controller processor of a controller included in the end node, a logical error of the message; and classifying, by the controller processor, types of the physical error and the logical error.
Claims17
An end node in an Ethernet-based vehicle network, the end node comprising:
- a processor including a controller processor and a physical (PHY) layer processor;
- and
- a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
- perform a monitoring operation of a signal on a port of the end node;
- detect a physical error in the port based on results of the monitoring operation;
- transmit information of the physical error to the controller processor;
- determine a type of the physical error based on whether a physical channel parameter of the signal matches with at least one of a predetermined physical channel parameter, a receive failure of the signal, a transmit failure of the signal, and a link failure;
- and
- classify the physical error with a critical error or a non-critical error based on the type of the physical error.
An end node in an Ethernet-based vehicle network, the end node comprising:
- a processor including a controller processor and a physical (PHY) layer processor;
- and
- a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
- obtain a message from the physical (PHY) layer processor;
- detect a logical error of the message based on a reference parameter;
- determine a type of the logical error based on at least whether a format of message matches a predetermined message formats, or whether the logical error is due to an error packet;
- and
- increase an error counter value per the type of the logical error.
An end node in an Ethernet-based vehicle network, the end node comprising:
- a processor including a controller processor and a physical (PHY) layer processor;
- and
- a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
- perform a monitoring operation of a signal on all ports of a switch;
- detect a physical error based on results of the monitoring operation;
- determine a type of the physical error based on information of the physical error based on whether a physical channel parameter of the signal matches with at least one of a predetermined physical channel parameter, a receive failure of the signal, a transmit failure of the signal, and a link failure;
- and
- classify the physical error with a critical error or a non-critical error based on the type of the physical error.
