HDA vs lane keep

[PalisadeMan]

Wanted to know what is the difference between HDA and regular lane keep. HDA is available on highways but lane keep is available always. I don't see any difference in my daily drive so far. Any insight please.

Highway Driving Assist has an additional function which sets the smart cruise to the speed limit programmed into the navigator. BUT you have to start the cruise at the exact speed limit for it to work. So if the speed limit is 65 mph on an interstate highway, set the cruise to exactly 65 mph. When the navigator says the speed limit is 70, the Palisade will speed up on its own to 70. And if the speed limit changes to 55, the Palisade will slow on its own to 55.

BEWARE, if the navigation data is in error, or there is a construction zone, you may be going the wrong speed, it does not read the signs posted on the highway.

Also be aware that in many parts of the country driving the exact speed limit can be hazardous to your health.

As far as Lane Follow Assist and Highway Driving Assist, they are the same thing. The Palisade does its best to keep you centered in the lane without direct driver control.

Lane Keep Assist is a watchdog that tries to get you back in your lane when the Palisade wanders out of the lane under your control. If it takes control too often, use your turn signal when changing lanes.

The manual has lots of text about how Highway Driving Assist, Lane Follow Assist and Lane Keep Assist won't always be there to save your bacon. These are NOT self driving cars folks.

when I am on LKA it tends to wander closer to the lines. When on HDA it stays much more centered. Do others have that as well or do both functions work exactly the same in terms of staying centered. I've tried this many times and there is a significant difference to the point that it actually crosses the lines a little before it corrects and then moves to the opposite line and corrects again.

It makes sense. LKA puts you back in your lane if you veer off it. LFA (and by extension HDA) attempts to keep you centered, so it'll react before you're off the lane.
