<strong>What</strong> <strong>is</strong> a <strong>vehicle</strong> <strong>HMI</strong>?<br />
<strong>HMI</strong> <strong>is</strong> about how the driver <strong>is</strong> able to interact with the<br />
<strong>vehicle</strong>. Main task <strong>is</strong> to drive the <strong>vehicle</strong>.<br />
Examples:<br />
D<strong>is</strong>plays and buttons and sound<br />
Pedals, levers and steering wheel<br />
Mirrors<br />
Safety superv<strong>is</strong>ion systems
Automotive <strong>HMI</strong> trends<br />
Influenced and controlled by<br />
User needs and demands<br />
Infrastructure<br />
Consumer products, e.g. iPhone, TiVo<br />
Laws and rules<br />

• Tailor GUI layout for different markets: Asia, Australia, Europe, Brazil, USA…<br />
• Share and move information between Cluster and Secondary D<strong>is</strong>play.<br />
Customization<br />
• Let the driver customize not only functionality but now also styling of graphics<br />
and colours to get an individual feeling.<br />
• Pre-defined driving g modes and p profiles; ; High-way, g y, City, y, Night… g

<strong>HMI</strong> in commercial <strong>vehicle</strong>s<br />
CONFIDENTIAL
The commercial <strong>vehicle</strong>
Why <strong>is</strong> <strong>HMI</strong> important?<br />
Human error <strong>is</strong> involved in 90-95% of all road accidents<br />
Ca 100 people people per<strong>is</strong>h yearly in heavy truck<br />
accidents<br />
PProfessional f i l ddrivers i spend d ca 9 hours/24h h /24h in i the h truckk<br />
Tight time schedules<br />
Make driving a more fun experience<br />
Save money
<strong>HMI</strong> Function<br />
Balance task/user capacity<br />
Graphical user interfaces and systems<br />
can ass<strong>is</strong>t driver for a safer, , more<br />
convenient and fun driving experience<br />
• Good interfaces make it easy for drivers to<br />
interpret situations and act accordingly<br />
• Passive systems alert driver in hazardous<br />
situations<br />
• Active systems automatically avoid<br />
accidents and support driving performance

Driver d<strong>is</strong>traction<br />
Wh <strong>What</strong> t <strong>is</strong> i driver d i d<strong>is</strong>traction?<br />
di t ti ?<br />
Too many and/or too long eye movements<br />
away from the “field relevant for driving”<br />
KKatja tj Kircher, Ki h VTI<br />
1/4 accidents <strong>is</strong> caused by driver d<strong>is</strong>traction
Driver d<strong>is</strong>traction examples<br />
Eating/drinking or preparing eating/drinking<br />
Chatting on computer<br />
Manipulating p g music/audio controls<br />
Multitasking<br />

11. W Warn for f d<strong>is</strong>traction di t ti itself it lf (teach (t h ddriver i not t t to<br />
get d<strong>is</strong>tracted)<br />
22. Adapt other warnings arnings (help dri driver er when hen<br />
necessary)<br />
3. Combination: adapt warnings and warn for<br />
“really really bad bad” d<strong>is</strong>traction
Adaptivity<br />
A Atechnical t h i l system t can make k ddrivers i observant b t off r<strong>is</strong>ks i k<br />
Consider in design:<br />
Drivers are sometimes already aware of r<strong>is</strong>ks<br />
City y traffic implicate p a high g level of driver awareness<br />
An automatic warning can increase workload<br />
An adaptive system might make driver solely aware of<br />
r<strong>is</strong>ks he/she not have not payed attention to<br />
Warnings imply more information to interpret

Stoneridge <strong>HMI</strong> goals<br />
With creativity, creativity innovative minds and technology build<br />
the next generation design with:<br />
Enhanced performance<br />
p<br />
Increased safety<br />
Increased user sat<strong>is</strong>faction<br />
…for systems that have<br />
O One system feeling f li<br />
Good usability<br />

Drome – Stoneridge graphics platform
<strong>What</strong> <strong>is</strong> a Digital Tachograph?<br />
Device that records the driving hours of the driver driver.
Digital Tachograph background<br />
Tachograph design driven by EU laws<br />
Specification written by EU, Annex 1B<br />
Focus on first products p has been to design g according g to<br />
specification and not according to user need.<br />
Extremely long and complicated change processes -><br />

User interface not very user friendly<br />
DDownload l d ti times very llong<br />

Digital Tachograph rev<strong>is</strong>ion 7<br />
Focus areas for improvement:<br />
Usability - <strong>HMI</strong><br />
• D<strong>is</strong>play<br />
• Buttons<br />
Performance<br />
• Download time<br />
• Card withdraw time<br />
• Power consumption
Tachograph D<strong>is</strong>play & Button <strong>HMI</strong><br />
<strong>HMI</strong> was not optimal – Improvements needed<br />
Two alternative ways<br />
• Do it like the competitor, market leader.<br />
• Do it right, what the users want.<br />
Solution:<br />
• Stoneridge Tachograph simulator was developed<br />
-> User input before actual implementation<br />
-> Button design could also be tested

Drome – Stoneridge Graphics platform
<strong>What</strong> <strong>is</strong> the target application of Drome?<br />
Instrument clusters for commercial <strong>vehicle</strong>s<br />
Secondary d<strong>is</strong>plays for commercial <strong>vehicle</strong>s<br />
Any type of embedded d<strong>is</strong>play application requiring fast<br />
and flexible <strong>HMI</strong> design at low piece price.
<strong>What</strong> <strong>is</strong> the Drome Platform?<br />
Customer independent tool chain for developing <strong>HMI</strong><br />
and graphics for d<strong>is</strong>play applications.<br />
Translates data from a PC based WYSIWYG <strong>HMI</strong><br />
design g tool to a down-loadable binary y format and finally y<br />
executes the <strong>HMI</strong> on a target system.

Drome Target Library<br />
Interprets the generated database into a <strong>HMI</strong><br />
and draws it on the d<strong>is</strong>play<br />
Library y runs on conventional 32-bit micro<br />
controller, for example NEC V850.<br />
