Nexyad and HERE Technologies are now working together to apply cognitive AI to road safety. Nexyad uses cognitive AI to aggregate extensive data sources in a vehicle in real-time and interprets them to assess whether a specific driving behaviour is appropriate given the surrounding context. Nexyad’s assessment, quickly delivered to a driver via a mobile phone, can be calculated from four sets of data only: HERE map, Global Navigation Satellite System, electronic horizon, and acceleration.
Nexyad’s real-time data aggregation platform provides two output values 20 times every second: the lack of caution of the driver and the maximum speed recommended given the road conditions – legal speed limit, road roughness, the topography of the road, weather, and traffic. Nexyad analysis, based on several thousand road accident reports, uses sets of rules from modern hybrid AI, including knowledge-based systems, deep learning, neural gas, PAC (Possibly Approximatively Correct) learning, game theory, reinforcement learning, and possibility theory, and fuzzy logic.
Insurers are using Nexyad’s platform to provide recommendations to drivers and generate a risk profile. For example, Brightmile, a start-up incubated by Kamet, AXA’s insurer tech studio, is using Nexyad’s SafetyNex software as one of the parameters of their smartphone-based telematics solutions for fleets. India’s Montbleu also relies on Nexyad’s SafetyNex for its smartphone-based app ‘ROAD-Drive it Safe’. Milla, the French autonomous electric shuttle, uses SafetyNex to adapt vehicle speeds according to driving conditions and alerts the service operator (onboard and off-board) to take appropriate action when the level of risk is estimated too high.
Nexyad has started to integrate the HERE HD Live Map to provide OEMs with Predictive Automotive Cruise Control services, whereby appropriate speeds are not only recommended but automatically implemented. Moreover, connected vehicles will use SafetyNex to assess the level of caution of their driving and will be able to adopt the appropriate speed even in unknown road conditions.
“We found that the maps from HERE are accurate to the centimetre and constantly updated to the second. Every detail counts for us – the topography of the road, the exact positioning of the crossing, and the school’s location. With our mission being to save lives, we cannot settle for anything less than the best,” says Gérard Yahiaoui, CEO of Nexyad.
“Nexyad’s SafetyNex software is one of a kind – not only does it provide a score for the lack of caution of the driver, based on the environment in real-time, it also recommends an appropriate driving speed. This is the future for Predictive Automotive Cruise Control systems, insurers, and autonomous vehicles,” says Gilles Martinelli, Director of Automotive at HERE Technologies.
