General Motors EN-V
Designed for urban environments and around an extrapolation of the P.U.M.A. prototype announced by GM and Segway in 2009, the EN-V was unveiled at the joint GM & SAIC pavilion at the Expo 2010 in Shanghai from 1 May through 31 October 2010. Three different vehicles are showcased, 笑 Xiao (Laugh), 骄 Jiao (Pride) and 妙 Miao (Magic).
The most significant feature of the vehicles is autonomous operation. The EN-V can detect and avoid obstacles – including other vehicles – park themselves and come to you when called by phone.
Accomplished through a combination of GPS, vehicle-based sensors, and vehicle-to-vehicle communication, this autonomous technology is an extrapolation of that found in GM's 2007 autonomous "The Boss" Chevrolet Tahoe created for the DARPA Grand Challenge (2007).
The EN-Vs can communicate with each other allowing platooning, with one or more EN-Vs tagging along automatically behind a leader. Also, if an EN-V detects another in close proximity, it can check what that other is intending to do and agree on how to pass it safely.
Powered by two electric motors, one on each wheel, and a lithium-ion phosphate battery, the EN-V has a top speed of 40 kilometres per hour (25 mph) and a maximum all-electric range of 40 kilometres (25 mi). The sensors and communications equipment which allow it to drive itself include short-range radio and GPS, as well as optical sensors, ultrasonic sensors and doppler radars. The two-wheeled balancing system the EN-V uses was developed by Segway, and it may be an extrapolation of that found in the P.U.M.A. prototype announced by GM and Segway in 2009.
The three vehicles shown use the same automobile platform but have unique exterior and interior designs.
Xiao Dimensions: 1,540 mm (L) × 1,420 mm (W) × 1,770 mm (H) (60.5 in × 56 in × 69.5 in)
Miao Dimensions: 1,520 mm (L) × 1,405 mm (W) × 1,635 mm (H) (60 in × 55 in × 64.5 in)
Jiao Dimensions: 1,500 mm (L) × 1,425 mm (W) × 1,640 mm (H) (59 in × 56 in × 64.5 in)
In October 2011 General Motors announced its decision to develop a second concept EN-V under the Chevrolet badge for use in field testing and demonstration programs in several cities around the world, beginning in Tianjin, China. The Chevrolet EN-V concept will add new features such as climate control, personal storage space and all-weather and road condition operation while several key elements of the original EN-V will be preserved, such as the small footprint, maneuverability, its battery electric propulsion, connectivity, and autonomous driving capabilities.
