![]() ![]() ![]() With the advent of distributed control functionalities the need has arisen for reliable communication network systems where different electronic control units (ECUs) are connected with each other through controller area network (CAN network) buses for sharing hundreds of critical signals. More specifically, it is related to a method and device for detecting open circuit failure by pin pointing location of the failure in CAN network cable of any electronic control unit. The present disclosure relates to communication networks where different electronic control units (ECU) communicate with each other over controller area network (CAN) protocol. The following specification particularly describes the invention and the manner in which it is to be performed. ![]() TATA MOTORS LIMITED, Pimpri, Pune 411 018, Maharashtra, India Title: “A METHOD OF DETECTING OPEN CIRCUIT FAILURE IN CONTROLLER AREA NETWORK (CAN)” pdfĨ5-Written submissions and relevant documents (MANDATORY). pdfĨ5-HearingNoticeLetter-(DateOfHearing-06-01-2020).pdfĨ5-ExtendedHearingNoticeLetter-(DateOfHearing-06-01-2020).pdfĨ5-Correspondence to notify the Controller (Mandatory). More specifically, the disclosure relates to deploying combinations of aforesaid monitoring strategies to detect and distinguish plurality of failure types namely Network local open circuit failure at CAN stub (or network branch) of transmitting ECU Network global open circuit failure at the main CAN bus Network local open circuit failure at CAN stub (or network branch) of receiving ECU and internal failure in operating tasks within the ECU.Ĩ5-FER_SER_REPLY. The present disclosure relates to a method for detecting open circuit failure by pin pointing location of the failure in Controller Area Network (CAN) comprising acts of monitoring (a) CAN Error-Passive failure, (b) CAN receive-message Time-out failure, and (c) CAN transmit-message Time-out failure, in any combination, in transmitting and receiving Electronic Control Units (ECUs), and recording corresponding Diagnostic Trouble Code (DTC) in the ECU to detect the open circuit failure. ![]()
