Abstract

A communication network implements a Universal Measurement and Calibration Protocol (XCP) policy. The communication network includes a plurality of nodes, each of the nodes being operably connected toa bus to send and to receive data communications to and from others of the plurality of nodes. Certain of the data communications include a Universal Measurement and Calibration Protocol (XCP) identifier indicating the presence of XCP protocol within the data frame. At least one of the nodes is configured to mitigate identified XCP protocol in accordance with the policy.

Description

Technical field [0001] This patent generally relates to a communication network for vehicles. More specifically, this patent relates to a vehicle communication network and a method for implementing the Universal Measurement and Calibration Protocol (XCP) protocol strategy in the communication network. Background technique [0002] Vehicles are usually equipped with one or more controllers or control devices linked through at least one network or bus structure. Vehicles usually have multiple electronic control units (ECUs) for various subsystems. Various ECUs can be provided by different vendors, use different processors, and have different memory structures. ECU suppliers can provide common ECU architectures to multiple original equipment manufacturers (OEMs), and OEMs can use standard protocols and data structures, proprietary protocols and data structures, or combinations thereof. [0003] The Universal Measurement and Calibration Protocol (XCP) standard defines a bus-independe...
