General Motors EN-V

From Wikipedia, the free encyclopedia
EN-V Pride (Jiao, 骄)

General Motors EN-V (Electric Networked-Vehicle) is a 2-seat urban electric concept car jointly developed by Segway Inc. and General Motors that can be driven normally or operated autonomously.[1][2]

Designed for urban environments and around an extrapolation of the P.U.M.A. prototype announced by GM and Segway in 2009,[3] the EN-V was unveiled at the joint GM & SAIC pavilion at the Expo 2010 in Shanghai from 1 May through 31 October 2010.[3] Three different vehicles are showcased, 笑 Xiao (Laugh), 骄 Jiao (Pride) and 妙 Miao (Magic).[4]

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, beginning in Tianjin, China.[5] In June 2014 General Motors announced it would commence testing of the four wheel EN-V 2.0 at the Tianjin Eco-city[6]

Driverless vehicle[edit]

The most significant feature of the vehicles is autonomous operation.[1][2] The EN-V can detect and avoid obstacles – including other vehicles – park themselves and come to you when called by phone.[1]

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).[3][4]

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.[1]

Shanghai concept[edit]


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).[1] 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.[7] The two-wheeled balancing system the EN-V uses was developed by Segway,[1][2] and it may be an extrapolation of that found in the P.U.M.A. prototype announced by GM and Segway in 2009.[3]

The themes[edit]

EN-V Laugh (Xiao, 笑)
EN-V Magic (Miao, 妙)

The three vehicles shown use the same automobile platform but have unique exterior and interior designs.

Xiao (笑)[edit]

Xiao, or laugh, was designed in Australia by the GM Holden Design Studio.[3] Its design is intended to appear friendly.[8]

Xiao Dimensions: 1,540 mm (L) × 1,420 mm (W) × 1,770 mm (H) (60.5 in × 56 in × 69.5 in)[7]

Miao (妙)[edit]

Miao, or magic, was designed at the General Motors Advanced Design Studio in California.[3] Miao's design is mysterious and high-tech.[8] It was also exhibited at the Walt Disney World ride Test Track as a Chevrolet

Miao Dimensions: 1,520 mm (L) × 1,405 mm (W) × 1,635 mm (H) (60 in × 55 in × 64.5 in)[7]

Jiao (骄)[edit]

Jiao, or pride, was designed in Europe by Opel and takes design cues from bullet trains and Chinese opera masks.[3] Its design is supposed to be chic and stylish.[8]

Jiao Dimensions: 1,500 mm (L) × 1,425 mm (W) × 1,640 mm (H) (59 in × 56 in × 64.5 in)[7]

Chevrolet EN-V 2.0[edit]

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 2.0, as the vehicle is now called, 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.[5] The new vehicle design as revealed in 2014 has four wheels and has two doors (one of each side).[9] Testing at the Tianjin Eco-city was due to commence in July 2014.
