Jeep Safety Feature?

[Trini]

Never experienced this before, and I don't see anywhere where it's a jeep safety feature, so here the incident that happened today.

I was driving on an overpass where it merges into another major interstate, with no emergency lanes, simply guard rails. It has two lanes. I noticed two vehicles in front of me in the same lane, with the one behind following a bit too closely, possibly because the car in front was going just a bit too slow, but then again, the road was curving.

I put on my blinkers to switch lanes to pass. As I near the car in front, they decided to switch lanes (no indicator), while my bumper was in line with the driver's door of the merging car. I was in no way speeding, and there wasn't even a need for the car to switch or merge. I drive a 4xe and had the regenerative braking on btw.

Not gonna lie, this was very unnerving, as I felt my only recourse was to brake immediately. So I honked my horn, and as I lifted my feet of the gas pedal, I felt the jeep accelerate. It happened so quickly, and prevented what could've been a terrible accident.

How did the jeep accelerate? The ramp wasn't downhill, and I had regenerative braking on, so me lifting my feet of the pedal, means the jeep will be slowing down. I googled safety features of the jeep (2022 Jeep Wrangler Sahara 4xe), and the only feature I could see is the Forward Collision Warning and Active Braking, which did not activate since the vehicle was to my right. Not sure what the field of vision is for this advanced safety feature though.

The question is, is this a safety function of the jeep, was there some fault happening (which might be another concern) or was it some divine intervention that happened? Has anyone had their jeep speed up to prevent a collision? I was definitely shook from the incident. What made this situation even more confusing, was that it was late at night, and there was no vehicle of the other car that tried to merge for at least a mile or more, and it was basically the two cars and myself on the interstate ramp.

Did it really accelerate, or did the regenerative braking just turn off? If at any point during regen braking that it detects a slip or the anti-lock needs to engage, the regen braking will be disabled until you accelerate again (source: RBS on Page 8 of Owner's Manual Hybrid Supplement).

Using the turn signal during adaptive cruise bypasses the vehicle in front of us. Could that be what you felt?

This answer makes more sense than mine. I didn't think of it, because I don't have that system on my Wrangler. If you had the cruise control set, but adaptive was restricting your speed, putting on your turn signal will return you to your set speed and close the gap with the vehicle in front of you.

are you sure about that?

Very, it's a mixed bag and is frustrating some times.

EDIT: Note, I would think there are more prerequisites than just the blinker, but it's certainly repeatable. It only occurs when you are prevented from making set speed by a vehicle already.

From the OM:

I wish the ACC had a more sensible controller. Mine will apply near 80-90% throttle and kick on the engine out of electric mode just to get back to speed.

Same experience. It drives like the accelerator is an on-off switch.

Fuk that!!! This kinda shit makes me even more happy that I got 2018… it’s already more computer assisted than I wanted, and plan on dumbing it down even more in the coming years….

Ill have to try this when I get it put back together never noticed this before

Sorry, probably one of those things you never notice until you know, and you'll hate it now.

So, with this "feature" if you put on your blinker but then can't get over right away your Jeep will just accel toward the vehicle in front of you? Or odes it wait until it no longer senses that there is a vehicle there and then floors it?

It is watching for that, from the FSM:

Using those same inputs, the DASM also allows for an overtake event to occur. When the host vehicle is trailing a slower moving object and the host driver activates the turn indicator, the DASM applies additional amounts of acceleration while still trailing the object vehicle to aid in a lane shift maneuver. In locations with left hand drive traffic, overtake aid will only be provided on the left hand side. The same applies for the right hand side. The DASM is able to determine the direction of traffic flow by observing oncoming traffic. The DASM will disable overtake aid if the DASM detects an object in the lane the vehicle is attempting to move into in order to pass the slower moving object vehicle. The overtake aid also disables or will not assist if the host vehicle is equipped with a Blind Spot Monitor (BSM) system that is currently detecting a vehicle in the blind spot of the host vehicle.

FYI I have had this alot of times. Cruise is set to 75, I am behind a car going 70. As soon as I see a clearing, I put my turn signal on, and the Jeep speeds up to enter the left lane. It doesn't wait until you enter the lane, it starts speeding up the instant you put on your turn signal. Gotta keep an eye on that.
