A couple trip reports I posted had noted some frustration with the lane centering and lane holding capabilities of Highway Assist, and several forum members encouraged me to have the system re-calibrated. So, I scheduled a service appointment with the Seattle Service Center, which by the way was a great experience from start to finish.
Here is the summary on my service document:
Cause: Test drove vehicle on highway I-90 and checked operation of Highway Assist for several miles. Was unable to reproduce excessive swaying in
lanes, but there was some mild tendency to hug one side of lane at times.
Corrections: Because this function can be highly dependent on individual road conditions, decision was made to perform calibrations on both the FMC
and the Front AD cameras. Both calibrations were completed successfully. Drove vehicle again and verified operation.
Labor Description Actions: FMC Static Calibration FMC Static Calibration Diagnostic; ADAS General Diagnosis ADAS General Diagnosis Diagnostic
I just completed a 250 mile trip, and the lane centering capabilities of Highway Assist are now much improved, including the tendency to hug the right side of the lane. The car still sways a bit in/through/out of curves, but it it now only a question of a few degrees, where before I imagined that the car going from side to side within the lane would look like a drunk driver up ahead. I didn't encounter the types of lane marking interruptions that would sometimes cause Highway Assist to actually leave the lane, but I suspect that this will be improved, as well.
The bottom line is that I now feel comfortable using Highway Assist when I am not in the midst of heavy traffic.
