Hi
@dippY22 and others
Whether AKIDA will be involved in in cabin monitoring in 2022/23 via Nviso or Valeo or Mercedes Benz is not dependent on the technology but ASIL certification.
The following explains ASIL:
“What is ASIL?
Definition
ASIL refers to Automotive Safety Integrity Level. It is a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles.
The standard defines functional safety as “the absence of unreasonable risk due to hazards caused by malfunctioning behavior of electrical or electronic systems.” ASILs establish safety requirements―based on the probability and acceptability of harm―for automotive components to be compliant with
ISO 26262.
There are four ASILs identified by ISO 26262―A, B, C, and D. ASIL A represents the lowest degree and ASIL D represents the highest degree of automotive hazard.
Systems like airbags, anti-lock brakes, and power steering require an ASIL-D grade―the highest rigor applied to safety assurance―because the risks associated with their failure are the highest. On the other end of the safety spectrum, components like rear lights require only an ASIL-A grade. Head lights and brake lights generally would be ASIL-B while cruise control would generally be ASIL-C.
How do ASILs work?
ASILs are established by performing hazard analysis and risk assessment. For each electronic component in a vehicle, engineers measure three specific variables:
- Severity (the type of injuries to the driver and passengers)
- Exposure (how often the vehicle is exposed to the hazard)
- Controllability (how much the driver can do to prevent the injury)
Each of these variables is broken down into sub-classes. Severity has four classes ranging from “no injuries” (S0) to “life-threatening/fatal injuries” (S3). Exposure has five classes covering the “incredibly unlikely” (E0) to the “highly probable” (E4). Controllability has four classes ranging from “controllable in general” (C0) to “uncontrollable” (C3).
All variables and sub-classifications are analyzed and combined to determine the required ASIL. For example, a combination of the highest hazards (S3 + E4 + C3) would result in an ASIL D classification.
What are the challenges of ASILs?
Determining an ASIL involves many variables and requires engineers to make assumptions. For example, even if a component is hypothetically “uncontrollable” (C3) and likely to cause “life-threatening/fatal injuries” (S3) if it malfunctions, it could still be classified as ASIL A (low risk) simply because there’s a low probability of exposure (E1) to the hazard.
ASIL definitions are informative rather than prescriptive, so they leave room for interpretation. A lot of room. ASIL vocabulary relies on adverbs (usually, likely, probably, unlikely). Does “usually” avoiding injury mean 60% of the time or 90% of the time? Is the probability of exposure to black ice the same in Tahiti as it is in Canada? And what about traffic density? Rush hour in Los Angeles vs. late morning on an empty stretch of road in the Australian Outback?
Simply put, ASIL classification depends on context and interpretation”
Confused so am I but perhaps confused is not exactly the right term. There are many, many industries and regulation is an industry where the only way to not be confused is to actually work in the industry. Our recent discussion about the ASX Rules is a case in point. (AND by the way this is the simplest explanation I have found.)
So where does that take us well to the presentation by Anil Mankar at the 2021 Ai Field Day to an answers he gave when he was asked the following questions:
“Audience: Are there any car manufacturers using your chips today?
Anil Mankar: They are evaluating technologies, we are developing some Lidar data set applications for them, they will probably, they may not use this current chip because this current chip is not ASIL compatible and things like that but we expect that they will, once they are happy with our network that we are working with them on they might ask us or they might ask one of their suppliers to develop a car certified ASIL certification and if we expect it to be embedded into the chip that are already going into the car, there are lots of companies selling camera chips into the car, there is no reason why they can’t take our IP and do it all ASIL compatible and all that but this current chip that we are developing to assist 28 nanometer is not certified for that but they are using this or testing all the network evaluating power performance and once they are happy we expect them, either them or their vendors, to be a IP customers for us.
(AN ASIDE-Clearly Anil Mankar in the last part is referencing Mercedes Benz who are certainly happy, and so he has stated an IP licence either with them or a Valeo for instance.)
Audience: Okay so you’re in development now but you’re not yet certified, is there a roadmap for that certification? Can you even ballpark a date or you don’t want to talk about it?
Anil Mankar: Actually we don’t have plans to be, customers we are working with are already ASIL certified to be in car like camera chip guys ultrasound, Lidar guys, so we’ll depend on them to because automotive certification all that will be a long process and we’re not trying to be a big manufacturer of IC’a our focus is to enable Ai into all of the applications by supplying the IP. (AN ASIDE-Clearly the camera, ultrasound, Lidar guys includes Valeo)
Audience: Thank you.”
So we’re does this leave us Nviso is demonstrating on a non ASIL certified AKD1000 chip. Nviso does not make chips. Brainchip does not make chips. They have to rely upon a third party for the chip and ASIL certification. This third party will already be in automotive either as a vehicle manufacturer or an OEM like Valeo, Renesas or MegaChips.
I believe that having seen what Nviso and Brainchip can do that monitoring a driver simply for fatigue, definitely would not require the full 80 nodes of AKIDA IP neural fabric nor all of Nviso’s algorithms.
So time will tell if BRN and Nviso are doing this from the 2022/2023 commencement date but I am firm in my belief that the performance and power savings offered by AKIDA that so impressed Mercedes Benz will mean as the switch to EV develops a pace that it is not ‘if’ but ‘when’ their astonishing combination will be adopted and become ubiquitous.
My opinion only DYOR
