2010 BMW Z4
Navigation system under development learns the drivers habits to improve efficiency

One common thing in science fiction films and books are cars that drive themselves. In the future, people simply jump into the seat and tell the car where to go and it drives them to their destination automatically.

We are far from fully autonomous cars for the masses, but BMW is developing a new navigation system that learns your habits to help improve efficiency that some view as a step in the autonomous direction. The BMW system is called ILENA (Intelligent Learning Navigation) and is a project underway at the German automaker right now.

The way the system works is by recording data on your typical daily commute as far as learning your route, road gradients, curves and braking points. The system also uses a camera to get a visual of your path. Once the path is learned, BMW claims the system could proactively reduce the power to your AC system to give you more power to merge onto a highway. At the same time power to the AC is reduced, the shift points for the transmission could be raised to provide better acceleration.

On a hybrid car, the system could be used to ensure that the battery is fully charged before you get into the urban portion of your drive to help reduce emissions and improve fuel economy. BMW claims that when the system is used in conjunction with its Efficient Dynamics it can save 5% to 10% in fuel consumption.

BMW's Andreas Winkler said, "Using all this information, the navigation system generates an electronic horizon which helps in energy management."

The system may be met with some concern by many motorists who feel that ILENA could be used to determine how they can drive their vehicles in certain locations.

Already done that...

Jeremy Clarkson on Top Gear had one of these BMW systems autonomously drive him around their test track last year. The BMW people showed up, drove the car around the track for a few laps, and then put him in it. It drove in sport mode, not economy mode. I am sure it must be on YouTube somewhere.

its not the same. it doesn't drive the car by itself. it changes performance of the different components of the car. read the article.

btw the system that drove clarkson around was pretty darn cool. but it doesn't use gps. it uses memory and a gforce sensor. it just remembers where the course is

A step in the autonomous direction... that is what I was commenting on. I am sure they have put these two functions of the same system together already. P3I is the law in manufacturing. (Pre-Plan Product Improvements!)

Valet fun!

Imagine being a parking valet. Bill Clinton drives up in one of these new German BMWs. Valet gets in and for fun tells the car to take him to Clinton's last position on the Navigation GPS...

The car drives down some alley, then suddenly the seat lays back flat.

Is this before or after the intern comes out of her apartment?

Goodie, getting head from my GF while driving will be much safer now!!

Or am I missing the point?

I don't think you are. Its the first thing i thought of. Driving stick while having your "shifter" polished is a little on the risky side.

Can she even find a wall to drive into without a nav system? Just stereotyping women with that comment, not necessarily just your gf.

Great, try explaining to the wife why your GPS map automatically zeroes in on the nearest titty bar...

me, I want driving to be as automated as possible. If I could sleep on my way from the carolinas to michigan, or california... GREAT. Maybe catch up on some reading, give people a call i haven't talked to in a while. In general, driving takes up too much of my time that could be better spent doing something else. Sure, a way to disengage the auto pilot would be necessary, but if my car could drive me around completely automated, I would sign up.

That is possible since last century, my friend, it is called train.

worse the rise in GPS aided thefts/burglaries.

case in point? a family goes to a local football game. thief breaks into their vehicle & steals their GPS (or just jacks the car). gps provides directions "home" & thief proceeds to said residence and cleans it out of valuable property while the family is STILL occupied at the game.

thanks...but i prefer my car to know as LITTLE about me as possible. no black boxes, no "on star", no location to "home" in my GPS.

Stop owning little shit dogs then.

I live in a pretty shitty neighbourhood but every guest I have had over usually asks as walking to my door "so do you get a lot of break ins around here?" And once the door opens and they see a couple of Katanas on the walls and a rotty at the door they usually respond to their own answer with "probably not eh?"

Personally i like having a GPS if im going away or whatever but if you can't find your way around your own town then take the god damn bus right? lol

I agree with you that i don't like GPSs but not for the same reasons. I like the idea of an autonomous car because that gets the morons out of the drivers seat. But i like being able to drive my car the way i see fit. Sometimes i like to do a couple burn outs in the parking lot. Or be able to bomb off down a dirt road that i see last minute as I'm driving some where(Jeep XJ ftw..)

Technology has always been a double edged sword. Nothing you can do about it really.

I don't mind them knowing, as long as there is some sort of voice recognition or other security before it shows you any location. Thats why when I use them, I do not add "home", I only use temporary locations and clear them out when I am done. Besides, the only time I use them is when I am away from home on a road trip more than an hour or two away. Otherwise I know enough about the local area within an hour or two of my place enough to get around.

Assuming you mean simply changing lanes and the automated cruise control finds that you are too close to the car in front, then it should slow down to increase the following distance, then resume speed once the preset following distance is achieved.

The speed adjustment is done while cruise control is engaged. Normally when you accelerate to pass, an intelligent cruise control will kick out and wait to see what you are doing.

Similarly if the car in front of you suddenly approaches your front bumper then an intelligent cruise contol would attempt to back off by slowing down or engaging the brakes to avoid collision.

If you really want to be able to tap the other guy before settling in behind him, then you only need to disengage cruise control then go after him :P

Adaptive following distance is just another collision avoidance feature. This feature means that you don't have to spend your entire trip watching the other guy's brake lights :P

I've got this feature on my 1999 CL 600. Yes, 1999. Dont worry, the cruise control and "radar" feature are well implemented. Don't be put off by a poor salesman that hasnt learned about the features and technology on a car they are trying to sell. Bad training? Or lazy saleman not informing himself? Both? Don't know the technology because of one duck in the sales team.

If you are overtaking the radar is pretty intelligent and doesnt slow you down. If there is a slower car in front of you indicating to go back in the slow lane while you are rapidly approaching it, just put your foot on the accelerator to stop the cruise control from slowing to avoid collision. Remember that the radar cant see a indicating car in front. While using cruise control, PLEASE, keep your eyes on the road. Dont go back and make a cup of tea!

Remember these systems are not to drive you automatically, but to avoid a collision in a situation where you may be distracted for whatever reason.

Most accidents occur due to a "surprise", like a car pulling out, that for that fraction of a second the driver didnt see... because the "other driver" did something unexpected.
