Green News: GM EN-V Concept

EN-V, which is short for Electric Networked-Vehicle, maintains the core principle of personal mobility – freedom – while helping remove the motor vehicle from the environmental debate and redefining design leadership. EN-V is a two-seat electric vehicle that was designed to alleviate concerns surrounding traffic congestion, parking availability, air quality and affordability for tomorrow’s cities.

Three EN-V models were unveiled today in Shanghai. They represent three different characteristics that emphasize the enjoyable nature of future transportation: Jiao (Pride), Miao (Magic) and Xiao (Laugh). The concepts will be showcased from May 1 through October 31 at the SAIC-GM Pavilion at World Expo 2010 Shanghai. Shanghai is expected to become one of the epicenters for the establishment of personal mobility solutions for the future.

While EN-V leads the way in terms of efficiency and technology, it also sets a new benchmark for vehicle design. For its debut, GM had design teams around the world provide their vision of what future mobility will look like. Xiao (Laugh) was designed by GM Holden’s design team in Australia, while the look of Jiao (Pride) was penned by designers at GM Europe and Miao (Magic) was designed at the General Motors Advanced Design Studio in the U.S. state of California.

EN-V’s platform has evolved from the platform of the Personal Urban Mobility and Accessibility (P.U.M.A.) prototype that was developed by Segway and debuted in April 2009. Segway has worked collaboratively with GM to develop and deliver multiple copies of the drivetrain platform that seamlessly connect to and power the various EN-Vs.

EN-V is propelled by electric motors in each of its two driving-mode wheels. Dynamic stabilization technology empowers EN-V, giving it the unique ability to carry two passengers and light cargo in a footprint that’s about a third of a traditional vehicle. It can literally “turn on a dime” within its own operating envelope. In addition, everything in EN-V is drive-by-wire, supporting its ability to operate autonomously or under manual control. The motors not only provide power for acceleration, but also bring the vehicle to a stop.

Power for the motors is provided by lithium-ion batteries that produce zero emissions. Recharging can occur from a conventional wall outlet using standard household power, allowing EN-V to travel at least 40 kilometers on a single charge. EN-V can also improve the efficiency of the public electric infrastructure since the vehicle can communicate with the electric grid to determine the best time to recharge based on overall usage.

By combining the Global Positioning System (GPS) with vehicle-to-vehicle communications and distance-sensing technologies, the EN-V concept can be driven both manually and autonomously.

Its autonomous operating capability offers the promise of reducing traffic congestion by allowing EN-V to automatically select the fastest route based on real-time traffic information. The concept also leverages wireless communications to enable a “social network” that can be used by drivers and occupants to communicate with friends or business associates while on the go.

This combination of sensing technology, wireless communication and GPS-based navigation establishes a technology foundation, pieces of which could migrate from the EN-V concept and potentially lead the way to future advanced vehicle safety systems.

The ability to communicate with other vehicles and with the infrastructure could dramatically reduce the number of vehicle accidents. Using vehicle-based sensor and camera systems, EN-V can “sense” what’s around it, allowing the vehicle to react quickly to obstacles or changes in driving conditions. For example, if a pedestrian steps out in front of the vehicle, EN-V will decelerate to a slower and safer speed and stop sooner than today’s vehicles.
