Ratings for a New Safety Era
Cars Are Getting Smarter
Smarter is Safer?
Front and side impact crash tests still form the backbone of most rating programs today — but priorities are changing.
NCAP's true influence comes to light in the fast adoption of head protection airbags, advanced seat belts, anti-whiplash seats, etc.
NHTSA started NCAP in 1979 — in the nineties the concept exploded onto the global scene.
DfT, FIA and SRA were instrumental in setting up Euro NCAP — today a consortium of 12 members and 8 test facilities.
Safer vehicles have a star role in the Decade of Action for Road Safety.
Euro NCAP's MPDB test addresses known limitations of the ODB test and promotes more compatible front-end designs.
Moving barrier: 1400 kg, PDB face; 50 km/h; 0 degrees and 50% overlap. Vehicle speed: 50 km/h. THOR-50M, Q10 and Q6
IIHS and US NCAP are focusing in on small overlap and oblique crashes that claim up to 25% of frontal crash deaths in the US.
Euro NCAP MPDB Impact
About a third of killed or seriously injured occupants in side impact are involved in far side crashes.
Far Side Crashes
Investigations into a Far-Side Impact Sled (FSIS) simulator
Sub-system testing meant that vehicle front-end structures became more forgiving in pedestrian collisions.
Areas modified for small overlap performance in the SOI test
Moving barrier: 2486 kg. RMDB, 90 km/h, 15 degrees and 35% moderate overlap. Stationary vehicle under test.
US NCAP Oblique MDB Impact

Safe transportation of infants and children requires dedicated solutions — still, good child protection does not carry sufficient weight in most NCAPs.

Euro NCAP's assessment includes vehicle provisions, CRS installation and Q6/Q10 testing

From 2010 onwards, NCAPs started to lock on to the emerging crash avoidance and driver assistance systems.

Towards Zero Fatalities
Traditional disciplines are important but they are no longer the whole story!
Cars are developing "senses" but they are still are far from being called intelligent.
9 of 10 crashes caused by human error
but human drivers are still way better than self-driving cars
Crash avoidance features reduce crashes
but effectiveness is still low and not all systems are good
Driver has more support
More systems are being offered
but not all features are equally acceptable or used
The Ironies of Automation
but new safety risks arise (cyber-security, hand-over, software error)
Reduced crash risk
Vehicle dynamic sensors, vision systems, GNSS antennas
Slip, steering, braking control, ECU, etc.
Steering system, braking system, HMI, engine management
Seatbelt, airbags, etc.
ACU, Domain Controller, etc.
but smarter vehicles may be giving drivers a false sense of security

Integrated Safety Ratings
NCAPs are slowly coming around to the benefits of an integrated safety rating.
Automated Cars in Mixed Traffic
Advanced Human Surrogates
Future ADAS assessment based on the critical cases of unsafe performance resulting from poor design and flaws in HMI.
The driver's role will gradually change from pilot to operator overseeing machine driving. Ironically, the role of the human may become more crucial for safe driving.

Regulation & NCAP
Will the age of crash test dummy dominance finally have to come to an end?
Collinear and perpendicular test configurations
Increased complexity: angled and lower severity test configurations, different occupant sizes
Corpulence and other body proportions, seating postures, muscle attenuation.
