Nissan demonstrates its new stop-and-start control with a countertop ramen-delivery vehicle

Think about you garage door opener, for example. It doesn’t have an intentional acceleration or deceleration curve. It just goes.

What I’m hearing is, if I could teach the garage door opener to accelerate and decelerate, it could open and close faster. That it doesn’t today because faster would terrorize the users.

@VeronicaConnor

However they are definitely smug.

Along with, having learned such a skill, it would definitely become smug.

If they break too hard and release too hard and the passenger lurches, it’s uncomfortable and anxiety producing.

Currently teaching the kid to drive, and I can 100% state that it creates anxiety. A little bit of motion sickness too.

Very, very impressive. Now if they could only put as much work into their vehicle styling.

In a system like this I’m imagining that the controller has some sense as to what the passengers in the seats are doing. The controller is probably then solving for a braking curve that minimizes deceleration in the passenger while also minimizing stopping distance.

This is what I said in the part about “good accelerometers” and “maximizing deceleration while minimizing forces”.

If you know the exact physical properties of inertia in the thing (in this case a bowl of liquid)

I now have this vision of a Nissan with a family and their ramen stopping and all of the family members are violently thrown around while the ramen does not spill a drop.

Animal models are always approximate in science. Ramen models even more so.
