Get ready for test driving your connected vehicle
An urban
legend talks about a story of one Mr. Fred in the '70s, who once complained
to Ford about his vehicle not starting when he goes out in the evening to buy vanilla-flavored
ice cream but works fine when he buys any other flavor. The vehicle was not
field-tested for fuel vapor issues in cold engines.
Since
then, the automobile industry has grown considerably, relying on computers and
data more than ever. The newer vehicles come connected out of the box. With an
average of 600 pages of the user manual and another 300 pages of supplemental
infotainment manuals, it is indeed getting exponentially complex with each
generation. It is estimated that the current modern automobiles have around 100
million lines of code and it may be more than 300 million lines of code in the
next decade. To put it in perspective, a commercial aircraft has around 15
million lines of code!
Over
the past decade, the customer shift has moved from vehicle reliability to the
overall experience of the vehicle. Engine refinements have reached a level
where almost all the leading OEMs deliver reliability. The focus is now more
towards the cockpit design, intuitive, informative yet simple meters and HU
consoles, and more tightly integrated human-vehicle connection as if the
vehicle is an extension of the driver's personality. The advent of artificial
intelligence, machine learning, augmented realities, hardware-agnostic software
architecture (SDAs), versatile, intelligent, and powerful sensors and ECUs,
etc., need to be foolproof than ever before. This has started becoming visible
in some of the recent JD Power IQS and other leading industry surveys. All this
adds a tremendous need for multiple user-friendly services on the vehicle, huge
but efficient bandwidth requirements, futureproofing the platform's flexibility
to launch new services, and a very strong backend servicing millions of
multi-generational vehicles in real-time. All this while, ensuring safety,
convenience, and comfort.
Vehicle
drive testing has become an integral and important factor in the current
automobile industry. The infotainment/connected features drive tests critically
augment the manual and automated tests that the vehicle undergoes in the lab
and on test benches. In simple terms, drive tests incorporate extensive tests
of the vehicle in the field. Mechanically, the vehicles get tested in the test
labs and test track simulating terrains and environmental conditions. However,
testing connected services of modern vehicles become tricky. The accuracy of
ever-changing demographics data, GPS data, readings from infrastructure and
vehicle, user inputs, being situational aware with no room for error are some
of the very few variables that a vehicle must understand, process, and act with
multiple fail-safe systems in the place. The biggest variable in ensuring the
safety and comfort of those inside and outside of the vehicle is human
behavior. Mathematically modeling human behavior and action is still an
evolving subject and to ensure that man and the machine work synchronously to
each other makes drive test one of the utmost safety requirement.
