Modern cars are designed on GUI simulation software like MATLAB, they model head accelerations few inches ahead of the most important headrest and run optimizer on variables. If it can be made into equations, they can cancel it.
btw, minimizing higher orders of derivatives improve passenger comfort only so much if the driver isn't so good at look-ahead path planning, you can't make coffee cup rides not sickening by software.
- constantcrying 2y ago>Modern cars are designed on GUI simulation software like MATLAB MATLAB is the programming language. You are talking about Simulink. But there are also dedicated software packages for car multi body dynamics. >you can't make coffee cup rides not sickening by software. Plainly false.

I'm not sure how this is false, but I'm also not sure what the person you're replying to is getting at. coffee cup rides have no driver and therefore no look ahead path planning at all. The entire appeal of these rides is that they exaggerate perception of third and higher derivatives by deliberately creating a chaotic field of view for their occupants, combined with constantly changing both the rate and direction of the acceleration of their squishy bodies in the rigid capsules to which they are loosely secured. Smoothing this out with software would be possible, sure, but then the result would no longer be a coffee cup ride. I feel like this is a poorly formed example.
- numpad0 2y agoI was thinking what would be the most steady and disorienting activity with higher integrals of lateral accelerations, and couldn't come up with a better example than a cup ride. I admit it wasn't a good one.
