Abstract

The technical solution describes inter-controller communication in a protocol-independent manner. For example, the method includes generating, by the transmitting controller, a protocol independent data frame comprising a mode identifier, a rolling counter, a message identifier, a signal group, a cyclic redundancy check CRC, the complement of the mode identifier and the complement of the rolling counter. The method also includes: sending, by the sending controller, the protocol-independent data frame to a first receiving controller using a first communication protocol; and sending, by the sending controller, the protocol-independent data frame to a second receiving controller using a first communication protocol. A second receive controller for the communication protocol.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Provisional Patent Application Serial No. 62 / 378,426, filed August 23, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates generally to communication between electronic control units (ECUs) in a vehicle, and in particular to communication between one or more ECUs associated with an electric power steering (EPS) system in a vehicle and other ECUs in the vehicle. Background technique [0004] The increasing reliance on automated driver assistance systems (ADAS) enables one or more controllers of various subsystems in a vehicle to communicate with each other. For example, communication helps subsystems share information, thereby helping subsystems react automatically to actions taken by other subsystems. [0005] Additionally, increasing vehicle safety requirements are driving system redundancy to a...
