The acquisition of test data is required throughout the product’s
life cycle - in prototype performance evaluation, reliability/durability
testing, duty-cycle analysis, end of line testing, and service and
aftermarket product areas. Both lab and on-road testing is needed for
components, sub-systems and entire vehicles.
As in-vehicle networks become increasingly more sophisticated
in terms of the number of controllers, the speed at which they
communicate, and the number of parameters available, they are a
virtual goldmine for the test engineer. If the data is already available on
the vehicle network, the engineer may only need to add any missing
sensors (or possibly none at all).
After reviewing the traditional approach of acquiring data directly
from sensors, the course will focus on the newer approach of
obtaining data from the in-vehicle network. Attention is given to the
complications of taking data from the in-vehicle network and how
to overcome them, current trends and applications, wireless data
acquisition (Wi-Fi and cellular), GPS, relevant technical standards,
and how to simultaneously acquire network data with direct sensor
measurements. Both PC-based and logger (flight recorder) data
acquisition will also be covered. In addition, a practical guide for
analysis and presentation techniques will be covered along with
examples.
Learning Objectives
By attending this seminar, you will be able to:
Acquire data from both in-vehicle networks and sensors
Avoid common pitfalls of acquiring and analyzing good data
Request messages and decode them to acquire engineering
parameters using various network protocols such as: CAN
(controller area network), J1939, ISO15765, J1708, SAE J1850,
KWP2000 and ISO9141
Choose the best analysis techniques to better understand and
present test data
Compare benefits of acquiring data with a PC vs. a stand-alone data
logger (without a PC in the vehicle)
Discover what a PC or stand-alone logger is capable of doing for
real-time data acquisition, analysis, display and storage of data
Identify an unknown network protocol
Reverse engineer data on the network
