Reference speeld in addition instead of percentage

Recommended Posts

I drive a Model S, In the configuration I can select how many kilometers it can drive on top of the speed limis and this is not a percentage. It would be nice ABRP could use addition instead of percentage.

For example, I now have it set to 104%, which at 100km/h is 104km/h but with 130 it is 139. The car would then travel at 134 which is a 5km/h difference. It would make the prediction even better.

I'm curious, do you typically drive a consistent speed above the speed limit? IE, if the limit is 50km/h, do you also drive at 54km/h?  I ask because at slow speeds the speed limit difference becomes substantial from a safety perspective.  Especially if you're a bit of a speed demon, the difference between 110 and 130 is not as huge as 50 and 70.  Driving at 70 on a road designed for 50 is substantially less safe than driving at 130 on a road designed for 110.

Teslas have a setting that allows you to put in a specific number of miles an hour that will be added to the speed limit. When you turn on AutoPilot that is what your speed is set to. So I use +8 on my car. That means that when I am on a 55 MPH highway I go 63 MPH, which is pretty standard for California. Maybe a little slow.

Yes, at 40 MPH I go 48, 25 I go 33, so that is more significant. If the car could do a percentage faster as ABRP can, I would use it. But since they are on separate algorithms the planning doesn't line up. Maybe until the car gets an update we could add this feature to ABRP?

Actually, something that ABRP could calculate is how FAST the car should drive on this segment to maximize the time spent on the road. If I am driving from LA to SF, that 400 miles mean I am going to stop at least once. If I drive faster I use up more battery, but I am getting there sooner. Highway 5 seems impervious to people getting tickets as long as they stay below 85 MPH.

But then I need to stop twice to charge, so did I actually save time? I bet there is a calculation to figure out the best speed to take a specific trip and arrive in the shortest amount of time.

I see that you also have the ability to calculate this based on prevailing winds, but they don't seem to use live data, I must put the winds in before I start driving. Could this be grabbed from the same people that TeslaWinds.com uses to track your headwinds?

The last piece (live wind data) is on our radar (pun intended).  Something we're still working on a good way to implement.

I've added this suggestion as a to-do item in our tracker, so we'll get to it soon, I hope!

Related to this point about live wind data, I'm wondering about temperature too. I'm thinking about a situation, for example, where you maybe start a long journey in a location with warmer weather and travel to a location with colder weather. When you enter an origin and destination, perhaps ABRP could look at the forecast temperature at the origin and at the destination (at the time when arrival would be expected) and use that data to more accurately calculate the impact of temperature on consumption. For a long journey, it may also be beneficial to look at the temperature at a number of points along the route.
