The value of driving risk notion
for Telematics, ADAS and Autonomous Driving

The value of driving risk notion for Telematics, ADAS and Autonomous Driving.

by NEXYAD

Every year, more than 25.000 persons die on roads in Europe which has the safest infrastructures anyway. Brasil, Russia, USA, have more fatalities and the situation is worst in development countries. Everywhere people are aware by these risk for their health or life. Driving can be dangerous for drivers and passengers, however most of people accept these risk fairly minimal (in average three dead by billion km in OECD countries) for all advantages of fast point to point terrestrial mobility. But by the way, what is exactly what people use to call driving risk?

Let’s take an example, if someone plays Russian roulette: probability to die is one on six when one pulls the trigger. If one decides finally not to play, probability to die with a bullet in the head disappears completely. If you pull the trigger, risk to die is 100% (although probability is 1/6).
Another example: if a car is static parked into garage, then driving risk is zero. On the opposite, if a car passes a stop sign at 20km/h, driving risk taken by the driver is equal to 100%: driver takes the full risk). Probability depends on the traffic at the intersection.

More generally, driving risk taken by driver (and we talk about “the risk you take” a priori) will goes from 0 to 100% depending on the adequate of driving behaviour to driving context. This driving context has several dimensions: complexity of infrastructure, traffic of other road users, weather conditions, etc. Inadequate of driving behaviour to complexity of infrastructure can predict 75% of accident.

NEXYAD SafetyNex in Media

Here is a news in French press that talks about the Academic Chair that the cluster
of startups and SMEs « MOVEO Groupement ADAS » organized with INSA Rouen.
NEXYAD is part of this cluster of high-tech startups and SMIs (on ADAS, connected
car, and autonomous driving) and is quoted in this article of Journal du Net (French spoken), they interviewed Mr Aziz Benrshair, director of the « Autonomous and Connected Vehicle » Academic Chair launched by INSA Rouen :
Comment ces partenaires contribuent-ils concrètement ?

« Ils assurent environ 50% de l’enseignement. Des experts de ces entreprises viennent enseigner sous forme de TP ou de TD. Ils transmettent leur savoir faire et expliquent les projets sur lesquels ils travaillent. La société Sherpa Engineering est par exemple intervenue sur les questions d’actionneurs, de prise de décision et de commande automatique. Nexyad a abordé l’analyse du comportement du conducteur, proposée par sa solution d’évaluation des risques d’accidents SafetyNex. Des partenaires historiques extérieurs à cette chaire, comme Valeo ou Vedecom, sont également intervenus. »

SafetyNex episode 3 : The Car Insurer’s Choice

SafetyNex by NEXYAD is a Driving Risk Assessment App/API for prevention (accompanied driving, young drivers, individuals, professional drivers, seniors) in every kind of 4 wheels vehicle. SafetyNex is worth for UBI (risk profiles, usage profiles) at the end of every trip; reduction of costs (lower rate of accident and in particular of personal injuries + transformation of some severe personal injuries accidents into material accidents); Detection of behaviour modifications in time and Distraction detection (mobile phone …) : under implementation.

SafetyNex episode 2 : Your Driving Assistance System

Nexyad has developed a smartphone App which is a driving assistance system that alerts the driver IF AND ONLY IF speed of the car is not adequate with the road infrastructure. Then SafetyNex allows the driver to slow down or brake BEFORE a situation of danger. SafetyNex is also available as an API to be integrate into devices or other applications.

SafetyNex episode 1 : Driving Risk Assessment

Nexyad explains in this video the key notion of driving risk. From zero risk when the car is sleeping into the garage to 100% risk when driving behaviour is by far not adapted to a particular road context.

Mov’eo is a Mobility and Automotive R&D competitiveness cluster, which since 2006 has been mobilizing its energies at the service of its members to meet the objectives assigned by the State to competitiveness clusters: to foster the development of collaborative projects between members, to contribute to development in the regions of companies, in particular SMES, and to promote innovation in the sector.

Created in february 2014, VEDECOM is a French Institute for Public-Private Partnership Research and Training dedicated to individual, carbon-free and sustainable mobility.

The new MOV’EO President quote NEXYAD SafetyNex at the beginning of its intervention…

SafetyNex can bring Artificial Intelligence into Autopilots in respect of ASIL ISO 26262

SafetyNex integration in the ASIL 26262.

Complex Automation MUST be ASIL ISO 26262.
Artificial Intelligence CANNOT BE ASIL ISO 26262 (by definition) and acts only on parameters of Complex Automation doing ++/– – variations, never skipping « reflexes actions » (emergency braking, etc), but allowing anticipation speed adaptation to reduce frequency of emergency situations (and then give more margin to reflexes actions and also improve comfort). Maximum acceptable Driving Risk can be changed depending on driving situation in order to set « aggressivity level» of HAV.

SafetyNex driving risk estimation during driving : anticipation of danger

SafetyNex estimates driving risk 20 times per second, during driving (real time).
On the following figure, you can see risk rising when approaching a stop sign with an inappropriate car speed :

Example of driving 1
Speed of the car is quite high before the STOP sign and Risk goes to the maximum with a vocal alarm to the driver which have time to slow down or brake to stop.

Now with a slower speed profile :

Example of driving 2
Speed of the car is lesser here but still too high approaching the STOP sign, there is a vocal alarm again but for lesser time.

And finally the « good » safe speed profile :

Example of driving 3
There is a good anticipation here before the STOP sign, speed is adequate and risk is very low, then null.

This estimation is computed INSIDE the local device (inside the car). Current implementation is on smartphones (IOS and Android), then computing of risk is completely done INSIDE the smartphone : that makes SafetyNex compliant with all driver’s privacu regulations and laws in Europe.

Applications :
. insurance and fleets : vocal alert when risk is too high. As you can see, it lets time to slow down and avoid potential accident. This leads to a reduction of accident rate and a reduction of personal injuries. Of course, risk values can be recorded to do stats (risk profiles) for UBI (Usage Based Insurance) applications. 
. Automotive : same application is navigation with risk alerts. But with a robotized braking system (ADAS), it is possible to trigger braking with risk value. In such a case, it is not emergency braking but rather anticipation braking. 

In addition, it is possible, in the case of HAD (highly Automated Driving) car, to control speed (longitudinal part of auto pilot) very easily : « if risk too high, then slow down », « if risk is low, then accelerate until risk becomes the max value you accept or until you’re at the speed limit ». You write your autopilot with very few lines of code !


Ground Reality with Nexyad Validation DataBase

Table ronde avec Nexyad sur le véhicule autonome à BFM Business

INTEMPORA and NEXYAD, members of MOVEO Groupement ADAS on Major French TV (BFM Business)

1st Nov 2017, the Tech & Co tv show on the subject : will self-driving car come sooner than expected ?

Nicolas du LAC, INTEMPORA, and Gerard YAHIAOUI, NEXYAD, presented their innovations and explained how the MOVEO Groupement ADAS helps to be stronger for their innovative startups.
Nicolas talked about RT-MAPS that is a software tool for R&D, making easy the task of developing applications with multiple sensors (cameras, lidar, radar, …) that of course are not synchronized and that must collaborate through algorithms of sensor fusion in order to get good objects detection and recognition.
Gerard talked about SafetyNex that is an onboard real time module that is the only module in the world that can estimate driving risk 20 times per second. Self-driving car can then know the risk it takes with and it simplifies the development of autopilot (example : « if risk too high then slow down »).
