Software Update 2023.50 -- Scheduled battery preconditioning & other useful improvements!

[SSteveEV]

"Improved throttle control when in Reverse "

That's great to hear because backing up to a trailer coupler and going just "half an inch more" is very difficult the way the throttle is mapped currently.

You said difficult, but you meant terrifying right?

Can someone explain why preconditioning is better than warming it up as you drive? Aren’t you going to eventually heat it up anyways?

It uses a significant amount of energy to warm up which results in reduced range.

So it’s useful when you’re plugged in.

can this be activated on demand? Let’s say I don’t know my schedule but when I’m almost ready, I’ll tell it to get started.

Seems like they have two major additions to make early next year - infotainment (which will be related to the start of LTE charging) and the camera view on the driver screen when turning left or right. Other than that it will be driver plus and navigation updates periodically.
I am expecting the monthly updates to stop by the middle of 2024 and the going quarterly since a lot has been done in the past 2+ years and I don’t see them doing monthly for ever.

Green light chime like Tesla would be awesome along with automatically folding the mirrors by either Alexa or location.

Anyone receive this update, yet?

I noticed if I have the R1S in highest and have steering at full lock, it almost feels like something is binding up like a real 4WD vehicle does. My R1T doesn't quite have that same sensation. Could be something with that.

I am sure it is just reduced steering weight at low speeds.

It is on Tesla So one would hope it will be similar behavior on Rivian.

I would rather see multiple places being able to set behavior of the vehicle similar to home.

The big one is being able to do it using shore power while plugged in. For some reason the current behavior when warming the cabin is to use the battery until it drops X% below the set point before it starts charging again.

Preconditioning the cabin should work manually without using a schedule, but I doubt the battery warming will work that way. But I could easily be wrong. Warming the battery also takes quite awhile, so it wouldn't surprise me if they restricted that to a scheduled departure so the R1 can figure out when it needs to start based on the battery temp and estimated departure.

I'm guessing most of the heat generated for preconditioning comes from the inverters being deadlocked by the motor. There is likely little heat coming off the armature, stationary or not, that can be captured. This especially on the quad with the splash oil system that doesn't interact with the coolant. The temp sensors we see are also likely the inverters.

It does "work that way", & it is an easy test for those in cold climates to see for yourself.

Rivian copied the Tesla design, & is pulling from the motors, not the inverters. & Yes, the Enduro's appear to be transferring heat much more efficiently in tests I have done.

Nice Christmas present from Rivian!

And this - blended braking. We knew that the Bosch system Rivian uses had this capability (in theory) - finally!

Regenerative Brake Assist
The new Regenerative Brake Assist feature improved deceleration performance in cold climates, on long downhills, and in vehicle high states of charge by blending more consistently and seamlessly with standard braking. To disable this feature, go to Settings > Driver+ > Regen Brake Assist.

Not sure this is a motor thing. Presumably after the update letting off the accelerator during limited regen will engage the friction brakes, thereby simulating regen and slowing the vehcile.

And/or ratio like cyber truck?

I'm not referring to the motors. I'm referring to the Bosch Regenerative Braking System. Several articles in the past mentioned that Rivian uses this OEM braking system, the same as Tesla. It's software driven, so vehicle manufacturers can implement whatever features they like.

"Like many other car makers, Rivian is using Bosch’s iBooster brake system. Even Tesla has used this system since they introduced partially-automated driving features into the Model S although Tesla has programmed it to use only friction braking when the driver steps on the pedal, presumably to guarantee the highest level of consistent braking feel."
