R1T Max Towing (by Now You Know)

[Max]

This made me wonder how it would do with Regen off (if it can be off). Because if the inverters are having issues or your SOC is at 100% your breaks and trailer breaks should be able to handle Max towing. What would you set your trailer break at with this setup?

Edit: watching the video is not necessary to answer my question: how would you tow with R1? Max Regen? Lower Regen? Regen off (I am not sure if this is an option)? What level trailer breaks in what kinda roads?

Brakes. They’re brakes.

im not giving these twits the click, what dumb thing did they find to whine about now?

Not a big fan myself. But the other guy pulled R1T to a gas station so I had to check it out. There is nothing really educational about the video but this along with TFL video made me wonder how would you really tow with R1T? No trailer break may maximize your Regen but increase the risk of jackknife and also if you lose Regen, it puts a lot of pressure on front breaks. If you use a lot of trailer break, you lose more range. I have never towed before but I am planing to so those of you that have some experience, please drop some knowledge on me on how you would use R1S, R1T to maximize range while staying safe.

If you have a lot of trailer break, there’s problems

It's quite simple. You do what you need to tow safely, which means you are constantly evaluating traffic, road, terrain and weather conditions, and adjusting as you go. Towing is not "set it and forget it".

That's why Rivian gives you the ability to set the trailer brake gain and manually actuate them. Regen should cover the majority of stopping power for a normal stop, but an emergency stop will necessitate using the trailer brakes as well.

What happens if the breaks brake?……. Or the brakes brake?….. Or the breaks break?…….?‍ We are doomed.

I’m not a trailer physics expert but I don’t like the idea of a ton of trailer weight pushing against the truck. I can’t wait to trailer my first pintle with this. It’s gonna be bangin.

What's the question? I'm not watching the video.

When towing, auto-regen (one pedal style) should be off. You need to control when to accelerate, and when to brake. It can regen in lieu of mechanical brakes.

Max re-gen will never capture all the energy from stopping; and of course the trailer brakes will waste some itself. Range will suck. Stupidly, Rivian can't capture energy from manual brake activation like the Leaf and others can even if it's within regen limits.

There's not much more too it unless they've never towed in a gas truck.

As much as I want to devour all Rivian content, I am not watching another video from these numbskulls.

You answered my question. I was just asking how would you tow with R1? My understanding is that, you would only use mechanical breaks (with the truck and trailer break).

About the statement: “Max re-gen will never capture all the energy from stopping”, although it is true that some of the energy will be lost due to inefficiencies regardless of what you do, it come close in Florida or any flat land, with conservative driving (slowing down gradually).

I am still curious why you would turn Regen entirely off? Regen will only add to your breaking power and reduce stress from mechanical break. You always have access to that break pedal. And Regen can still communicate with the trailer breaks. So it sounds to me, it would be beneficial to have it on with the level of trailer break controller set to what fits your rout adjusting with the roller at the wheel. What is the downside of having trailer break on ? Do you think at Max and even lower setting it is too dangerous and could cause jack knifing?

Right now, Rivian regens based on one-pedal driving and not based on brake pedal usage. Other vehicles due interrupt brake pedal usage and apply regen up to the regen limit before mechanical brakes.

Why? IDK, you'd have to ask Rivian.

As for capturing all the energy, generally the regen limit is fairly low. When you have a trailer, its unlikely you will stop that slow (and obviously, any stopping done with trailer brakes, will be 100% non-regen capable as there's no regen on trailer axles).

I want regen off for safety. When you are towing, there are a variety of situations where loss of control can be prevented by throttle application, manual braking, coasting, braking at another time, etc. For example, if I am going downhill with a flat-towed vehicle behind me around a corner, braking can be dangerous as the weight pushes the rear of the truck out. You want to get to your desired speed before the corner and if you must brake within, the brakes should come proportionally from the trailer. The regen is tied to one-pedal driving on the Rivian and its very hard to tether the pedal to a middle point that is "coast".

My trailer has surge brakes which are automatically actuated, this in combination with the regen on the Rivian seems to work quite well. One pedal driving + manual braking when needed seems to be fine, you can adjust the amount of "coasting" you want by applying the pedal accordingly.

When the truck has cruise control engaged, the adaptive cruise is disabled, so you have to manage your following distance manually.
