My two issues were this.
1) Steering effort is too low; small, unintended muscle movements get transformed into unintentional steering inputs. This is more noticeable at high speeds (80-140 mph). Torque vs yaw is too low is spot on.
2) Steering does not provide enough feedback; traction...
I think I am going to have to fold on the idea. I am looking for a manual rack, which will solve all my problems (more or less). It may take a bit to go lock-lock, but even in tough competition rallycrossing, that doesn't happen too often. If I can live with the current 3 turn L-L rack, I...
Actually, it doesn't need to be normalized. I always do (for what I work on), so thats why I put it in.
Lets say you are sampling at 10khz, and you want to examine your vehicle with a steering input of 2.0 Hz. You can do less, but I would make sure your sinusoid has at least 3 cycles, so...
I will give it a shot. Camber plates are easy to come by, and they usually have front/back adjustments for kingpin angle.
Heavy is an issue too, though. Consider a situation where you are driving on a highway, and something suprises you. Your first instinct will be to flinch. If a...
Taking the FFT of a signal will decompose it into each contributing frequency, giving you the amplitude and phase.
If you are trying to measure the yaw lag to a given steering input, you don't need a full FFT. You just have to:
- Normalize your data (scale it to +/- 1)
- Multiply your data by...
I am familiar with the valve, but Subaru touts it manufacturing finesse with that part, quoting tolerances into the micron level. My machining resources and vehicle downtime do not enable me to go that route.
A castor adjustment would be nice, but I would like to reduce steering assist by...
Todays power steering systems seem to cater to the two finger driving style by overboosting the steering assist. I personally find this discomforting at lower speeds, and flat out dangerous at highway and track speeds. A simple unintentional twitch makes a newer PS car change lanes. It is...
