    As much as I like Tesla and the Cybertruck- I have to point out that the 2 ribbon cables which provide steering input commands to the rack and pinion motors does not qualify as redundant, much less "double redundant" Both ribbon cables share a single connector which means the connector becomes a single point of failure that impacts both systems. This concerns me as it would not qualify in an industrial application as "redundant" much less when applied to a "people mover" application.

    Thought the exact same thing. There also seemed to be an implication the steering motors were powered by that ribbon cable, which is clearly not the case. Also, no doubt the front module just communicates with the steering motors/sensors using can bus. Also find it intriguing that a massive connector almost the size of a human hand is apparently a marvel compared to a simple, compact and cheap 4 pin connector which would otherwise be used (12v, gnd, can high, can low).

At least before I would ever consider buying one. Also... I would hope that if there is a failure, the computer doesn't allow someone to continue driving the car. 50 to 100 miles to get home and it should shut down until the problem is corrected.

    Confused by REDUNDANCY terminology. Also had same issue with the Boeing computers description I have seen elsewhere. For instance you showed what seemed to be a twin cabled lead and called it double redundant. Is this a difference between American English/Math and English English/Maths? In English English a double cable would simply be called a (single) redundancy. A double redundancy (two redundancies) would be three cables. Likewise "triple redundant" system would be four systems. Or did I not see/hear all the redundants being described?

    Planes have fly by wire systems, they also have legally mandated service schedules, detailed log books, controlled operating conditions and highly trained pilots who are legally obliged to report any deviations from the flight envelope. Redundancy is only useful if the failure of the primary systems are apparent to the operator, if one cable fails the system degrades. Putting two cables in parallel doesn’t suffice and can make things worse, if one cable gets mangled and shorts it may disrupt the second.

    Impressive tech - thanks for the tour guys. Couple thoughts come to mind on truly redundant systems - I would want those ribbons routed differently through the vehicle structure vs side by side, and I certainly wouldn’t want them terminating in a common connector. It would be interesting to know if that conversation happened during the design phase - especially on the common terminal and if someone pulled up data to say the chance of failure at that point was so small it wasn’t remotely worth designing two different interface points.

Triplr Redundant to a SINGLE control unit is adequate to guarantee an acceptable level of safety such that any fault will automaticallly force the car to go into a safe state to protect the car and its occupants from an accident.

    My guess is that the third sensor is not for safety or redundancy. Odds are that ZF/Tesla went with two servomotors on the front steering rack in order to provide enough steering power to steer this giant tire/wheel combo in certain off road environments. Anyone that's ever worked on a dedicated offroad racing truck would understand this. I believe the third sensor is for power management between the two servomotors since they have to run synchronously all the time. This is not a design for redundancy.

I would love to know how this system was made resistant to interference, or if Tesla perhaps found that twisted pairs are not needed and differential signalling works just fine over this flatcable design. It would be helpful to know how this cable is routed in the actual car. Second of all, I would be interested to know how many contact points are present on the connectors.

You can see the male connectors on the SbW rack actuators (split into BIG power and communication seperate). Each one - no way that blue one is connected to the SbW system directly! I also highly doubt it is 100% ethernet. And redundancy terminology is also mixed up in the whole video. The power is coming from a different wiring to the power packs (each probably >1kW, you don't run >20A @ 48V on that tiny ribbon cable!). And then they get the steering commands from another gateway/ethernet switch connecting feedback actuator (driver steering wheel) and the SbW gear.

    So the Tie Breaker sensor would be polled and if it was significantly out of synch you would get an error code to have the car serviced soon, but if one of the main actuator position sensors failed, then I wonder if it would disable that actuator and then rely on the 2 remaining position sensors in a limp mode to get the car to a service. Or perhaps the 2 good sensors could operate both actuators and operate more normally with the error code. Triple redundancy is pretty cool.

    I think it is actually just continuous. By that I mean every input is polled in real time--probably more than 100 times per second--and whichever two sensors are closer to agreement for that particular polling event are assumed to be correct. If there is a repeating discrepancy by the same sensor where it is the odd man out over some preset time span, then the system will flag it as defective and signal a fault that needs attention.

    Unless this system is a poor design the sensors and actuators as independent. They're packaged together for convenience. What happens when a sensor fails is up to the software. I can tell you what I think makes sense. Read all 3 sensors all the time. If any sensor disagrees or fails to respond we still have enough information to drive the truck but should a 2nd fail we don't. That could be very bad news so the truck needs service. *An error code alone would be a bad idea.* What the software allows the driver to do is up to Tesla. If it were an airplane we could continue to fly with 2 and even 1 sensor. With the car one has to allow the car to safely stop. We don't want people driving around with less than 3 good sensors but we don't want to endanger them by forcing their hand at an 'inconvenient' moment. There are both engineering and legal issues here.

    That sensor is actually a plastic box containing two completely independent sensors with two independent circuits. Which means that the two sensors are actually quadruple redundant. This way they can look at each pair independently and when one is in agreement and another one is also in agreement but slightly different they can measure that there is a slight difference but if it fails in a way where one of the four sensors is significantly off It can ignore it and make an assumption about which one is bad. There's a lot more information you can get.

    Heads Will Roll Amidst a chaotic month for Tesla - even by its continuously plunging standards - Facebook cofounder and multi-billionaire Dustin Moskovitz has made some pretty dire predictions for the automaker, accusing it of committing "consumer fraud on a massive scale." "This is Enron now, folks," Moskovitz wrote on Threads, referring to the corporation that went bankrupt in 2001 after it was exposed for one of the biggest accounting frauds in history. "It may keep going, but people are going to jail at the end." His concerns stem from a graph Tesla shared to mark a key milestone: one billion miles driven using Full Self-Driving, the company's highly fraught advanced driver assist system. He then compares it with a new graph released during Tesla's latest earnings call - an event that came with its own eyebrow raising moments. The point of the side-by-side is this: according to Moskovitz, the automaker is wrongly recognizing its deferred revenue - revenue for a product that hasn't been delivered, like an annual subscription fee - as earned revenue through the wider release of its Autopark feature last month. This is a sketchy move, Moskovitz claims, because an earlier version of Autopark was already released with FSD years ago, resulting in inflated numbers. "The data is presented in fraudulent ways, and it doesn't say what they claim it says even when they make it up," he wrote.

    Airplanes have redundancy on all crucial systems, but Cybertruck doesn't have redundancy on power for example. So if power fails, you will lose steering. There's a reason why other brands still have mechanical backup on drive by wire systems. Also the amount of electronic overhead on this system leads me to believe it's not as cheap or as light as its mechanical counterpart. As far as boats, we've seen what happens when they lose power, they collide into bridges because they lose steering, for example.

    Here's a question: would the Steer-by-wire system be able to perform what amounts to "dynamic wheel alignment"? I would think that the CyberTruck could perform micro-adjustments to the wheel alignment as the vehicle is moving to minimize rolling resistance. Maybe this has been mentioned at some point but I have not seen or heard anything about it.

    Not sure what you mean. The only parameter a steer by wire system could change is toe in. And for that it would need a split rack which doubles the number of motors and sensors a much more complex design. Or am I in left field.

    No. You can clearly see the steering rack geometry is pretty standard with the usual way of adjusting alignment manually with a spanner. Both motors work together to drive the same rack. There are 2 for redundancy/safety in case one fails.

    Q: Here's a question: would the Steer-by-wire system be able to perform what amounts to "dynamic wheel alignment"? A: no, well not at least with this system in the way it's currently configured, but that IS an interesting thought you have as it would simply have to be configured in the way Porsche ALREADY does it with the Rear Wheel Steering option available on the 911... that is to say, the current generation 992 (by virtue of being a rear engine mated to a transaxle) is forced to implement the use of Rear Steer by way of 2 separate actuators (1 placed at each wheel) that are not connected as would normally be with a standard EPS rack, therein technically they are able to move INDEPENDENTLY of one another for optimal geometry (think: Ackerman Steering)... to that end your idea of Dynamic Wheel Alignment DOES in fact exist at least in prototype form, yeah the mighty VW Group just debuted it 3 months ago iirc on a Lamborghini Huracan and it's called called AWC (Active Wheel Carrier). that's right, sorry Tesla but you lose again, unfortunately your CEO's Ego is simply not big enough to overcome the DEFICIT Tesla has to an OEM like VW who actively participate in Motorsports and Racing. again i repeat: "Anytime you win Leman 19X since 1970 (mind you someone hadn't even born yet) you learn things that the laymen and pretenders DO NOT..."

    Have we worked out what happens with the steering if the vehicle no longer has power? Will I still be able to steer the wheels to safely manoeuvre the vehicle off harms way? I think this type of situation is more likely to happen than having triple redundancies for system failures.

    You have a main battery and an auxiliary battery. If the main battery fails then the vehicle has no motive power but the auxiliary battery can still drive the steering system. If Aux fails then the main battery can provide power. If both fail then regenerative braking can provide emergency power.

    On ehuge benefit of by-wire steering is the ability for the system to decide what steering roadwheel angle to apply no matter what the driver input to the handwheel is. The biggest problem when calibrating a dynamic stability control system is drivers who "wang" the handwheel all over the shop, upsetting the system. With by-wire steering, you can perfectly control vehicle yaw with a roadwheel steering input as well as, or in preference too, a brake yaw application. Add in machine vision and lidar, and you can finally break the age old problem of drivers simply getting target fixated on the thing they are about to hit, and as a result hitting it. In advanced driving we teach "look where you want go, not where you don't want to go" but for most drivers, and emergency is so rare, unfolded quickly and un-expectidly, and as a result, a lot of fundamentally avoidable (through handwheel inputs in conjunction with braking) are not avoided at all....

    Wenn Du sowas willst oder brauchst, ok - aber ich schalte im Winter je nach Straßenglätte und Schneelage sogar das ESP AUS - aus dem einfachen Grund, weil es hoffnungslos überfordert UND eben viel zu langsam und träge ist. Bei sportlicherer Fahrweise, ist das System sehr schnell überfordert. Probiere es mal aus, ein außer Kontrolle geratenes Auto MIT und dann OHNE ESP wieder einzufangen - dann weißt Du was ich meine. Bei mir, war es also genau anders herum, dass das "überforderte ESP" ständig und verspätet MEINE Lenkkorrekturen dann praktisch zunichte gemacht hat. Man spürt dann regelrecht, wie das ESP mit 0,5 Sekunden immer zu spät eingreift.
