Ever wondered where/when/for how long your ABS is being activated?
Analysis of my data on a wet day at WGI revealed a very interesting information.
On second 46-47 I was coming into the bus stop (inner loop) on a wet day at WGI.
46.00sec
BRAKE PRESSURE 410-420
LF, FR, RL, RR all on 410-420 psi
46.14sec
LF 438
FR 326
RL 280
RR 280
46.26sec
FL 414
FR 319
RL 206
RR 200
Now the interesting part is that BRAKE PRESS stays the same roughly the PSI of the wheel with the most pressure. In this case BRAKE PRESS stays the same ~400-410 psi
BRAKE PRESS measures what the driver is doing.
The individual wheels called "BRK_FL_PRESS" report what the car is doing. (FL, FR, RL, RR)
The the above was sampled at 10Hz.
I bumped the frequency to 20Hz to get more granular data. I read some place that the ABS can pulse at 30 times per second. If that the case AIM should update their option to allow 30Hz. Currently 20Hz is the fastest option.
