Embodiment Construction

[0021] In an exemplary embodiment, the data monitoring device passively monitors and converts data messages transmitted within a vehicle network (eg, a controller area network) for use by other portions of the vehicle network. To this end, the device determines the protocol of the data messages and then converts these messages from the determined protocol into another protocol or format that can be used by other parts of the vehicle network (eg modules controlling the exhaust system). Importantly, by passively monitoring messages, preferred embodiments of the data monitoring device do not interrogate other network components / devices, do not interrupt the functionality of other network components / devices, do not send requests for data messages, and do not actively Interacts with other network components / devices to obtain data messages. Instead, the device simply "listens" for data traffic on the network. Details of exemplary embodiments are discussed below.

Abstract

A method manages data traffic in a vehicle controller area network having a plurality of functional modules. To that end, the method and apparatus passively receive data messages transmitted across the controller area network. The data messages are formatted in one of a plurality of proprietary protocols. Next, the method determines the protocol of the data messages. The determined protocol is oneof the plurality of proprietary protocols. After determining the protocol, protocol logic translates the data messages (transmitted across the controller area network) from the determined protocol toa given protocol. The protocol logic is configured to translate the data messages from any of the plurality of proprietary protocols into the given protocol. The method then transmits the data messages, in the given protocol, onto the controller area network for use by at least one of the functional modules.
