Eco Route

 

Just wondering if any one else has updated their Nuvi and added the Eco Route function?

I updated last week and a couple of observations with how it now routes me if i have the 'Less Fuel' rather than the 'Fastest Route' which I normally use it routes me very differently. I have now found out to conserve fuel it does not route me on any roads where the speed limit is above about 50 MPH. Not sure why it does that as in the Less Fuel option It no longer routes me on highways etc...

Has anyone else seen this?

I believe when they calulate

I believe when they calulate the miles per gallon of a car they use a speed of 45-50 miles per hour. If that is the case then I would expect the GPS to route you only on roads that the max speed is 50 or less, thus saving gas.

I've download the new update but have not done any testing.

would vary person to person

I am sure this would vary based on the vehicle profile information that you supply

ecoroute

I also ddl it but havn't tried it. Can it be enabled?

Staying with Fastest Time

I downloaded the update and tried some routes with different settings. EcoRoute is closer to Shortest Route than Fastest Time. Doesn't save much in fuel costs.

I decided to keep mine set for Fastest Time, but kept the Challenge on because it is interesting to see how various conditions affect the score, and it is supposed to keep a travel log.

I intend to experiment a bit more, but for my daily commute, after a day or two, I went back to Fastest Time as well smile

I think I will mess around with the Challenge around town over the next couple of weeks...but I will be really interested to see the changing score on an interstate, between 60mph and 80mph. shock

MPG calculation

I've started playing with this feature and can't figure something out. I put in a highway meleage rate of 37 mpg and a city rate of 32 mpg. I also calibrate my mileage to 37 mpg but the Fuel Report always shows a higher mileage rate, something around 40 mpg. It doesn't matter how many times I recalibrate. My normal drive is about 55 highway miles. Anyone have any ideas?

ecoroute

I do a rough calculation in my head everytime I fill up, every 3 days, so I know the actual mileage my car gets but my Nuvi tells me I am getting better mileage. I think a lot has to do with the way you accelerate and decelerate. The unit is probably doing some kind of calculation based on that and gets a different value. It seems like the calibrate function should fix that.

I also noticed that the best eco score is at 45 mph, as noted in another reply. I took a few mental notes on the way in to work this morning while monitoring my score.

50 mph score 76
55 mph score 73
60 mph score 66
65 mph score 72

Kind of interesting how it jumps around.

It will be intersting to see what others observe.

I know I'm going to get flamed for saying this, but I don't care.

You guys need to take the ecoroute data with a grain of salt. Remember that this program was created by the same folks who couldn't even get a currency converter to work properly for two years.

I agree 100% with GadgetGuy2008. It's all an estimation. The estimation can't take every factor & variable into consideration. How would ecoRoute know that the vehicle is badly out of tune & the spark plugs need replacing, the engine timing is way off and the air filter is plugged full of years of dirt? How would ecoRoute know that I'm driving my '94 V8 Mustang like a maniac, burning out from every stop light, constantly timing my 0-60 acceleration time...

I find it an interesting and useful tool, but no more than that.

MPG calc

My 265WT does the opposite. The calculated mileage number is lower than the highway number that I inputted.

I'm not going to flame

I'm not going to flame anyone. I understand that Garmin is just trying to get on the green bandwagon. I think it is just the engineer in me that wants to figure out how it works. If I put in a mileage rate for my car that I know is correct and the unit tells me my mileage is higher, then I know this is not working correctly. Maybe it is something Garmin needs to look at. The only thing it seems to do correctly is calculate the cost of your trip. I'm wondering if there is a way to get it off my unit.

Perhaps the difference can be seen in what is being calculated and reported. The Garmin is reporting an 'instantaneous' fuel efficiency based on the calculation it has performed over the specified route and period. Your calculations are an average based on miles driven and fuel consumed covering a much larger span of time and distance.

My car will calculate it's fuel efficiency and I've seen it range from 18 to 30 MPG depending on where, how, and when I begin the calculations. Currently, after several tankfuls and a mainly city driving, it is showing a little over 21 MPG which is pretty much in alignment with the EPA estimate and my calculations over the past year.

I have noticed that in vehicles I have been in that will calcualte mileage. The ecoroute fuel report indicates an average fuel economy though and this is much higher than when I do an actual calculation.

Re: no expressways

yes, I have done the update on my nuvi 205w and have come up with the same thing -- it will not route me to any of the local expressways. I have tried every setting. It is discouraging -- it used to before. Perhaps the right answer is to remove eco route.

I'll try this later. Let me know if any of you have done the update from 2.70 to 2.80 and have run across the same problem.

are you certain that you didn't change your avoidances?

and that you have chosen Fastest Time and not Less Fuel?

Re: Jim

Yes, my only avoidances were u-turns and unpaved roads. I tried choosing Fastest time and shorter distance separately. The rep at Garmin said I should try reseting factory settings...

It is impossible for EcoRoute to give anything but a guess while you are driving. It can see how fast you are driving, how long you stop at a stoplight and how quickly you get back up to speed. All valuable data, of course. But without being able to monitor the actual fuel being consumed at those precise moments, all it can do is guess.

A real AVERAGE is useful, but that takes a couple tankfuls to give you actual accurate data on fuel consumption.

I had the EcoRoute on since last Friday (but routing still for "fastest time"), and just filled up today. I checked the results for the first time today and looked at the estimated mpg, and it was actually pretty close to my estimate (I just use miles driven since last fill up / gallons). Of course I'll take the estimate with a grain of salt, but I was pretty surprised how relatively close my estimate vs the EcoDrive estimate was.

Just curious

What would EcoRoute do if you hop on a plane or ferry and leave the GPS on in car mode? I bet you'd get some interesting numbers / scores. Gotta try this next trip.

Travel Log

The only benefit I see is if you leave the challenge on, it will keep a log of every routed trip that you can refer back to if you need the info.

I also notice it gives how much the trip is going to cost in gas using the route it gives you.

It's a good thing that there's GPS systems or I would be ... always lost!

Score of 90

I got 89 score for doing 80mph at Toll. If the speed is kept constant the score bump up to 90.

Eco Route Travel Logs

"The only benefit I see is if you leave the challenge on, it will keep a log of every routed trip that you can refer back to if you need the info."

The trip logs that can be accessed under Eco-Route are generated whether or not the Challenge is enabled.

Just Curious

"What would EcoRoute do if you hop on a plane or ferry and leave the GPS on in car mode? I bet you'd get some interesting numbers / scores. Gotta try this next trip."

Heh. I do wonder if they have a the line
"if(speed > 200mph)
then ignore;"
in the code.
Ideally, you *should* be able to disable the function so that it doesn't collect data that would mess up the calculations. I move the GPS between 2 cars, so it will never be very accurate, though I suppose that deleting the "bad" trip logs might help, if they are in fact the source of the data used for the calculations.

It would be easer...

It would be easier if the thing would just let me put in the gas I bought and do the math for me! Or at least offer that choice for the people who, like me, always have their GPS on when the car is moving.

I gave the "EPA Estimated Gas Mileage" figures to my Nuvi765t and let her rip. And even though my Hybrid gets way better gas mileage on he highway than on the city, it likes to route me via surface roads for the whole 20 miles to the office rather than taking me a mile south to the interstate, then 900 feet from the interstate to the office.

I would think that if at the end of the week I told the thing I had bought 6 gallons of gas it would know that I had done X miles of freeway driving and Y miles of surface street driving and so calculate my mileage for each more accurately.

Heck, it should even use that when it takes into account what the most economical routing is.

But no... It would rather that I sit at every stoplight between Lakewood and Parker just to keep me off the interstate!

ecoRoute

I have a Nuvi 785T with ecoRoute check out my YouTube video. The MPG rating and is pretty accurate.

Why won't this update work

Why won't this update work for my 780?? My new 265wt can use it. Why my more expensive and supposedly featured up GPS not have this for an upgrade or option is baffling.
Sent question to Garmin, reply was no effort to incorporate this into 780 would take place (paraphrased).

recent units supported only

You have to remember that Garmin seldom (if ever) add new features to old units. ecoRoute was one time they did add a new feature that was not included on the original unit and did it only for the most recent units. The 7x0 series is over one year old now and has also been discontinued. Garmin simply would not add anything new to the 7x0. In fact, they still need to fix the lingering stuttering issues on "select" 7x0 series units.
