Acceleration After Switching Lanes

[FrankieJ]

When I have activated Cruise control and am forced to switch lanes as I approach a slower vehicle it takes a long time for my R1T to accelerate to my set speed. This can often be dangerous if you move to a lane where there are vehicles traveling faster speeds. I understand I can accelerate myself but it would be great if Rivian had a feature that would allow the vehicle to accelerate at a fast rate.

This scenario happens quite regularly to me also. I have learned to change lanes early so that the truck never starts to slow down for the slower vehicle. I think this is an area where the Driver Assistance software is still improving and this should become much smoother in the future. I would like for turning on the blinker to allow the vehicle to maintain the set speed so I can get closer to the slow vehicle before changing lanes. My Ford vehicle with ACC does this and it makes lane changes much smoother.

I also encounter this every time I try to switch lanes. Hopefully the experience will continue to improve.

Drives me nuts that they can’t program this in. I had the same issue with my Tesla (not sure if they’ve addressed it yet either as I don’t have a Tesla anymore).

My 2015 Mustang with just adaptive cruise (no lane keep of any kind) will do this so long as you’re using your turn signal to switch lanes. It works very well with the only caveat is if the lane you’re going in suddenly slows it can be a bit butt clinching LoL. That’s an almost 10-year old car (and with a manual transmission to boot!) ?

Agreed. I have defaulted to manually intervening with the skinny pedal when switching to an open lane as to not cause troubles for the traffic around me or myself. Thankfully it does not disengage the CC so, its become a minor annoyance at this point.

My 2014 wagon accelerates as soon as you indicate a lane change, its way better than what Rivian has programmed right now. They'll catch up eventually

Love my truck, but most of my complaints can be solved with a dumber version of whatever feature they are trying to perfect in the interim.

Need to change lanes much sooner for smoothness to occur. If you're late acceleration is limited as vehicle is too close before the change and reaction is to slow down.

So we're saying we want Rivian to program the vehicle with our human driver bad habits?

 

[SPITmadFIRE]

I think it's good actually that the vehicle doesn't accelerate wildly when it determines nothing is in front of it.

I call it “rubberbanding”.

My 2020 Jeep had a feature that specifically accelerated really well when passing a vehicle on the left. It was even documented in the manual. Did a great job.

It's not a bad habit to maintain speed when signaling and lane changing to pass...quite the opposite......you shouldn't be jamming on breaks, moving over, and waiting to accelerate if the purpose was to pass in open space....

I 100% agree with that but I wasn't suggesting that as being the bad habit. The bad habit is waiting too late to start the passing maneuver.

I agree it could be improved a bit. To avoid this, I just make sure to change lanes before the vehicle detects the slow-down if possible.

I really dislike adaptive cruise control in any amount of traffic for this reason and many others. In found that setting it to the greatest following distance and then changing to the closest following distance right before starting to pass helps with this problem, but that leaves too much room in front and somebody will merge in. So I stopped using it.
