Development of VeNetSpy: a Generic Monitoring Software for CAN-based ECUs and In-Vehicle Networks 2010-01-0196
During the development process of automotive electronic control units (ECUs) and
in-vehicle networks connected via CAN bus, an efficient software toolset that
can be used to monitor the work process of ECUs and the work load of the bus is
indispensable to ensure the product quality, as well as to shorten the
development cycle and hence reduce the cost. A generic monitoring software,
VeNetSpy (In-Vehicle Network Spy), which consists of a communication module
(CM), an in-vehicle network configuration database (VND) at application layer
and its management tool (VND Editor), a message parsing module (MsgParser), and
an application module (AM), has been developed. The CM module acts as a
middleware between data link layer and application layer to encapsulate the
difference among different CAN interface devices, and provides AM module with a
set of unified interfaces to manage communication devices. VND is an
object-oriented database used to model the topology of in-vehicle network and
describe the properties of CAN messages transferred among various ECUs and the
configuration of signals contained in the data field of corresponding CAN data
frame. MsgParser is an independent module used to extract the actual value of
signals from the data contained in a CAN data frame. The AM module is an
integrated environment used to trace the CAN messages among ECUs, parse the
messages of interested and draw graphics of signals according to their
description configured in VND, as well as calculate the parameters representing
the statistical characteristics of communication bus.
