I attended the 2011 International Consumer Electronics Show in Las Vegas, and had the opportunity to look for sensors in a variety of applications. General Motors two-wheel EN-V concept vehicle provided a great example.
Driven in a variety of modes, including autonomous driven over a programmed path, the electric vehicles demonstrated both tracking and collision avoidance capabilities. Using sophisticated sensing technology, the EN-V detected obstacles in its path, including another EN-V and even pedestrians, and automatically came to a stop.
The by-wire vehicle used a touch screen display to obtain driver input. For both an outside and inside experience, check out the video.
