Gathering Insight from Big Engineering Data
Problem statement:
“Democratization of Data (analytics)” –
making analytics available to ALL users in an
organization, from the data scientists to
product engineers and business analysts. [1]

Data, data, everywhere.

Insights (Engine Fuel Consumption and Efficiency)
Understanding of Real-world
driving patterns
Design Value based on calibration
driven by real world data
Optimization of Fuel Consumption
and Shift Schedules
Driver Variability (FFT of Throttle
Position)

Insights (8 mile traffic)
Traffic Patterns (the case for roundabouts)
0.0351 Gal/car at the intersection
12 cars a minute on the average
A saving of 121.3 gallons of
gasoline per day if the traffic lights
were replaced with a round-about.
A rough saving of 4.5 million
pounds of CO2 per year.

Typical Pains
CAN Data Analysis
– CAN data available as multiple files
that are “too large”
Data Logger : Vector GL1000/2000
One 32-Gbyte SD Card /1 test car, 1
month
Typical annual data intake
– 4-14 Tb (industrial automation OEM)
– 7-20 Tb (automotive OEM)
Historical and Archive Data
– Petabyte scale data from old
programs and fleet programs
Many kind of Signals
– About 100 (Speed, Fuel, Temperature,
GPS, etc…)
– Sampling Rate:
10msec,100msec,1000msec
Many analysis items: over 200 Values on specific event
Min, Max, Average, Sum
Graph, Histogram Chart, Scatter Chart
Need for advanced analysis and
visualization
