ADAS glossary and how the 4 innovative modules of NEXYAD can simplify everything

ADAS ISA

NEXYAD has been developing 4 software modules (RoadNex, ObstaNex, VisiNex, SafetyNex) for ADAS and road safety applications. Those 4 modules are designed to be deployed in series :

. smartphones

. aftermarket ADAS

. telematics

. intelligent cars

Here is the glossary of main ADAS and how thos 4 modules can be used in every case.

Intersection Assistant

SafetyNex estimates driving risk, onboard and in real time. SafetyNex estimates adequation of vehicle speed when approaching a difficulty of the road infrastructure. This adequation is translated into a value called “driving risk”, and SafetyNex alerts the driver when risk is too high; this includes the cases of intersections, roundabouts, school areas, pedestrian crossings, traffic lights, curves, etc ... (all types of infrastructure).

Collision Avoidance System (CAS)

RoadNex which detects bitumen free-space and ObstaNex which detects obstacles can be used together to build this function (easily to couple with lidar or radar).

Blind Spot Monitor (BSM)

RoadNex which detects the road and ObstaNex which detects obstacles, are currently being integrated by an OEM for the detection of blind spot on buses.

Lane Departure Warning System (LDWS)

RoadNex detects the lane (borderlines and bitumen free space). RoadNex knows therefore when the vehicle is not or centered on the lane.

Adaptative Light Control (ALC)

VisiNex Onboard detects fog, heavy rains and, more generally, poor visibility conditions, which require restoration of visibility including lighting and wiping, but also the adaptation of vehicle speed.

Traffic Signs Recognition (TSR)

SafetyNex reads all road signs on the digital map (no need for a camera, it is the company HERE that updates road signs informations at an increasingly accelerated frequency: 2020 objective, continuous update over the air). Traffic lights status (red or green) is not known at this date but there is a standard in Europe and soon traffic lights will be equipped with transponders.

Automotive Navigation System (ANS)

SafetyNex alerts driver before a dangerous situation during the navigation, thus letting him / her time to slow down and avoid a potential accident. It is a real value add to navigation (navigation with safety alerts).

Forward Collision Warning (FCW)

RoadNex which detects bitumen free-space and ObstaNex which detects obstacles together detect potential collisions (easily coupled with lidar or radar).

Adaptative Cruise Control (CC & ACC)

SafetyNex estimates at each second whether or not speed limit is crossed and also estimates driving risk. It is thus possible to regulate speed, on the one hand, in order to remain below peed limits and, on the other hand, in order to keep driving risk below an acceptable limit value. With SafetyNex, these two operations: follow the road rules and comply with the recommendations of a road safety monitor are extremely simple to achieve.

Driver Monitoring System (DMS)

SafetyNex checks at each second that the driving behavior is adapted to the context of the road scene. If not, estimated driving risk rises. When driving risk assessed by SafetyNex is high, this means that the driver is unsuitable for driving and is putting himself/herself and his/her passengers in danger. This is a very functional way of monitoring the driver.

Intelligent Speed Adaptation (ISA)

This is the most complex function to perform without SafetyNex. With SafetyNex, on the contrary, it becomes easy. SafetyNex estimates at each second whether or not speed limit is crossed and also estimates driving risk. It is thus possible to regulate speed, on the one hand, in order to remain below peed limits and, on the other hand, in order to keep driving risk below an acceptable limit value. With SafetyNex, these two operations: follow the road rules and comply with the recommendations of a road safety monitor are extremely simple to achieve.
