GM has respected the promise made to the Hall of New York the slid year when it has made to see the mysterious object that it had called P.U.M.A. (Personal Urban Mobility and Accessibility), a kind of Segway for two, conceived in exactly joint venture with l’ American company that today supplies means of transport characterizes them to the forces dell’ order. Now GM has introduced in preview to Shangai, practically dall’ other part of the world, concept the EN-V that will be shown the public dall’ 1 to 31 October in pavilion SAIC-GM during the World Expo 2010, to Shangai. EN-V is for Electric Networked-Vehicle, that is a vehicle electrical worker connected to a network of others accredits, a concept that maintains the fundamental principles of mobility unchanged characterizes them, that is freedom and independence, redefining some but completely the design aspects and contributing at the same time not to make of the vehicles motor object of the debate acclimatize them. Of the P.U.M.A conserve the essential factors. Concept the EN-V is pushed from two electric motors, arranged everyone in ciascuna of the two lateral wheels, than they are not limited to produce l’ necessary energy all’ acceleration but acts directly also on the control of the deceleration and the refrained one. The peculiarity is in the diameter of sudden turn that is the same one of the Segway and the P.U.M.A.: ” he is able to steer on a currency from a centesimo” they emphasize in GM, practically rotates on own axis. GM, and its strategic partner Chinese SAIC Group (Shanghai Automotive Industry Corp) propose, it like alternative all’ automobile. Hung 500 kg less and it has a length of approximately 1,5 meters, while un’ medium automobile today hung more than 1.500 kg and is three times longer dell’ EN-V. In more, the cars than today demand a space for the parking that exceeds the 10 mq and pause in order more of 90% of the time. The reduced dimensions of EN-V and its decidedly advanced maneuverability allow instead at least parking 5 vehicles in the same space. L’ EN-V moves to emissions zero pushed from the two motors fed from an A battery the Ionian ones of lithium that is recharged in its turn through a taken normal school of the domestic net, in the thought timetables more convenient. L’ declared autonomy in order now is of 40 km. L’ extraordinary evolution of this vehicle to two wheels is in the connettività, like had anticipated a year to us ago Larry Burns, vice-president of the department of research & development and strategic planning of General Motors: ” Electrical workers imagined of the vehicles little ones, agile, that they succeed to localize the other vehicles and to avoid eventual collisions. Now projected these vehicles in a somigliante net to Internet and you will obtain an incredible improvement of the possibility to move in the cities, to find places where to be able to park and to connect themselves to the business nets and sociali”. L’ EN-V uses a combination between the technology Global Positioning System (GPS), the connettività with the other vehicles and the net and a system of appraisal of the distances premises that it of of being guided manually or in automatic modality. With automatic guide EN-V it can contribute to the reduction of the ingorghi street, choosing the faster distance based on the information received in real time. With l’ I use of logons wireless, guides and passengers could be always connected to the net during the travels, in a real one social network. This ability to ” dialogare” dell’ EN-V, or with the other vehicles, or with infrastructures could determine a drastic reduction of the number of automotive incidents. Through appropriate sensors and television cameras, l’ EN-V, in fact, can ” accorgersi” than it is happening around, reacting in the more opportune way to eventual obstacles or repentini changes of the guide conditions. As an example, if a pedestrian had without warning to find itself in front of the vehicle, this automatically will decelerate till to catch up a surer speed in order then to stop in times many more breviums regarding puts into effect them vehicles. The materials employed for the realization of the structure and the cap dell’ EN-V are the carbon fiber, the acrylic Lexan (polycarbonate) in various colorations and materials, all members employed for the cars from race and military and aeronautical uses. With regard to the performances dell’ EN-V, the reference to progenitor P.U.M.A are d’ obligation: it can catch up the 35 miles/now (approximately 56 km/h) and could arrive till 35 miles like autonomy (56 km) that it would cover with a cost of recharges par to 35 cent in the States. While the cost of this innovative vehicle to two wheels parallels (than keeps in feet thanks to a system of gyroscopes hold that it in perfect equilibrium) could cost from ” a quarter to a third party of the supported cost in order to acquire and to use un’ automobile currently in commercio” according to how much it had anticipated Burns to us.
