GM, DaimlerChrysler, BMW Premiere Unprecedented Hybrid Technology

http://www.theautochannel.com/news/2...27/005036.html

The state-of-the-art full hybrid system, whose components are being co-developed by General Motors Corp., DaimlerChrysler and the BMW Group for production beginning next year, represents a major automotive industry milestone due to the unprecedented fully integrated combination of electric motors with a fixed-gear transmission.

As a result of its low- and high-speed electric continuously variable transmission (ECVT) modes, the system is commonly referred to as the 2-mode hybrid. However, the sophisticated fuel-saving system also incorporates four fixed gear ratios for high efficiency and power-handling capabilities in a broad variety of vehicle applications. During the two ECVT modes and four fixed gear operations, the hybrid system can use the electric motors for boosting and regenerative braking.

In summary, the four fixed gears overlay two ECVT modes for a total of six operating functions:

* Input-split ECVT mode, or continuously variable Mode 1, operates from vehicle launch through the second fixed gear ratio.
* Compound-split ECVT mode, or continuously variable Mode 2, operates after the second fixed gear ratio.
* First fixed-gear ratio with both electric motors available to boost the internal combustion engine or capture and store energy from regenerative braking, deceleration and coasting.
* Second fixed-gear ratio with one electric motor available for boost/braking,
* Third fixed-gear ratio with two electric motors available for boost/braking.
* Fourth fixed-gear ratio with one electric motor available for boost/braking.

The result is trend-setting hybrid technology that provides superior fuel economy, performance and load carrying capability.

The full hybrid system being co-developed by General Motors, DaimlerChrysler and the BMW Group has an overall mechanical content and size similar to a conventional automatic transmission, yet this full hybrid transmission can operate in infinitely variable gear ratios or one of the four fixed-gear ratios.

A sophisticated electronic control module constantly optimizes the entire hybrid powertrain system to select the most efficient operation point for the power level demanded by the driver.

Key Advantages

When compared to conventional hybrid systems, this avant-garde hybrid technology, relying on both the ECVT modes and the four fixed gear ratios, provides advantages in combined (city and highway) fuel economy, dynamics and towing capability.

Traditional hybrid systems typically have only one torque-splitting arrangement and no fixed mechanical ratios. These systems are often called ďone-modeĒ hybrids. Due to their less capable mechanical content, one-mode hybrids need to transmit a significant amount of power through an electrical path that is 20 percent less efficient than a mechanical path. This requires usually substantial compromise in vehicle capability or reliance on larger electrical motors, which can create cost, weight and packaging issues.

General Motors, DaimlerChrysler and the BMW Group have conceived a full hybrid system featuring four fixed mechanical ratios, within the two ECVT modes, to reduce power transmission through the less efficient electrical path. Consequently, the electric motors are more compact and less dependent on engine size.

This combination of two ECVT modes and four fixed gear ratios eliminates the drawbacks of one-mode hybrid systems to allow for efficient operation throughout a vehicleís operating range, at low and high speeds. It also allows for application across a broader variety of vehicles. It is particularly beneficial in demanding applications that require larger engines, such as towing, hill climbing or carrying heavy loads.

Existing internal combustion engines can be used with relatively minimal alteration because the full hybrid system imposes no significant limitation on the size or type of engine. It enables the three global automakers to package internal combustion engines with the full hybrid transmissions more cost-effectively and offer the fuel-saving technology across a wider range of vehicles.

Initial applications are suitable for front-engine, rear- and four-wheel-drive vehicle architectures, but the full hybrid system has the flexibility to be used in front-engine, front-wheel-drive architectures in the future as well.

this is gonna be huge... SUV's with 30 + mpg

I have an SUV, and I get about 22-26 MPG depending on where I'm driving. I like the vehicle quite a bit. But color me unimpressed with the idea of spending a bunch of money on an overhyped SUV that barely gets better fuel economy than what I'm already driving.

Hopefully the Japanese will do something worthwhile in this space soon, since it appears that GM is too busy making half measures that please the oil industry.

You must have one of the few. My damn minivan doesn't even do that well. I can't wait for the thing to die so I can finally get something with decent mileage. Still not an SUV though.

Well, at least MPG ratings are moving up. Not as fast as gas prices.... :banghead:

But at least they are moving up.

But the big uestion is is it real? In the first gas shock suddenly cars began getting huge mpg gas figures I mean like 25 to 60 mpg. Same car same engine detuned a bit. After a big investigation they had to restate the mpg. Hope this is not the case here.

I'm curious... you have a smaller SUV, right? What kind is it... I believe the big concern is towards the larger SUVs like Tahoes, Yukons, etc.

What makes me laugh is that there are still a large # of people driving Hummers in Dallas... mostly soccer moms and people that would likely never take the thing off road. Sad, actually.

What are ya driveín?
Is it a 9K # SUV with something like a 5.7 L V-8, or bigger?
Thatís where theyíre aimín this, I personally like the idea, particularly the modular design that allows use with a variety of power plants.
It could even lead to retrofitín existing platforms, thatís a good thing IMO.

Ha ha ha ha. Actually, you're pretty fair from what I've seen. Maybe I haven't seen all of rexjake's threads, but I just didn't think that his were any worse than a lot of stuff that's here in our lounge. You do what you need to do. I'm not questioning your authority. Just thought I'd inject my 2 cents (not sure if it's even worth that :) )

It would have to be the 2wd V6 and driving down the side of a mt to get 26, their current 6 2WD only gets 22mpg.

Well thatís good for you and Iím glad you like your rig, Iím a fan of ĎYotaís also, but realistically the 90 hp and 150 lb/ft of torque those four bonsai squirrels are makeín isnít gonna tow a 5K# stock trailer.
