Segway, GM Partner On Two-Wheeled Electric Car 394

Posted by kdawson
from the keeping-it-in-balance dept.
Slartibartfast was one of many readers sending in news of GM's partnership with Segway to develop a two-seater urban electric vehicle. It's called the Personal Urban Mobility and Accessibility, or "PUMA." This is just a prototype, so don't get your credit card out yet. Its total cost of ownership could be about 1/4 that of a traditional car, GM says. The prototype runs for 35 miles, at a top speed of 35 mph, on lithium-ion batteries. It features the now-familiar Segway balancing technology, though fore-and-aft training wheels are visible on the prototype. Some commentators have likened it to a high-tech rickshaw, others to a golf cart. Engadget describes how the ride feels.

    Add a third wheel and suddenly now you don't need thousands of dollars of gyroscopes and such.

    • by sarahbau (692647)

      Exactly my thoughts. A 3 wheel design would also use less energy since it wouldn't have to use motors to keep it balanced.

      Or add two more wheels, a couple more seats, a larger engine, and enclose it so you're better protected at higher speeds...

      Obviously this is just GM wasting more (of my) money. A cell phone acting as the dashboard? Some proprietary wireless communication between pumas? Destined to fail.

      Yup, and I'd love to see how it manages an emergency stop!

      A far better design would be two electric drive wheels at the front and a simple free steering wheel at the back. You've got all the advantages of this when it comes to size & simplicity (no complex steering rack), but you then don't need all that complex balancing software, it's more stable both at rest and in motion, it uses less power, and has far better emergency brakes.

      Oh, and it doesn't fall on its arse when the battery runs flat.

          That would depend on the configuration. If you have the two wheels up front, and the rear wheel the one with power, that changes the dynamics considerably.

    • by RyoShin (610051)

      I agree, but the lack of the third wheel can probably help in adapting it for an automated-rental style system, as well as extra parking room (a big deal in places like NYC). They have such rental systems in other countries, where you rent a bike/mini car from an automated machine, and I imagine such a thing would be useful in large American cities.

      It would certainly save money, but then so would just adapting a golf cart.

      They actually want to use "collision avoidance". Vehicles would be outfitted electronically to "exchange speed, direction and position data, then one of them could make a decision to brake in an emergency situation to avoid an accident". In principle this is a great concept, but given that most vehicles don't have this yet, that's not something you can solely rely on for the time being.

      I suspect GM may include some sort of control for controlling the direction of movement. If so, you could, y'know, turn. I doubt it'll be any less safe than bicycles and motorcycles in that regard.

      Walking is an excellent option and I do so whenever possible. However, it's tricky to walk at 35mph; I never got the knack.

      Something like this looks like it'd be an okay option for someone who needs to travel a fair bit within a city metro area. I'm strictly meh on it from what's said in TFA, but I don't think your specific criticism is particularly valid.

      Yeah, but with this thing, after you collide at 35mph the car will right itself automatically using gyroscopes. Just hang onto the controls and start screaming for help!
