Cohda Wireless DSRC Demonstrations
Copyright Cohda Wireless 2008,2009
During SAE Convergence 2008 in Detroit, USA, Cohda Wireless demonstrated the ability of its radio to enable reliable vehicle-to-vehicle safety applications. The following live vehicle safety demonstrations were performed:
- Intersection Collision Warning: Warning drivers of potential side impact when entering an intersection. This application was demonstrated in an open intersection and in a closed intersection;
- Electronic Brake Light: Warning following driver of a braking leading vehicle; and
- Rear Collision Warning: Warning of potential rear impact from a following vehicle.
The demonstrations were conducted on public roads, providing a real world urban environment and traffic conditions, approximately one half mile northwest of the Cobo Exhibition Centre in downtown Detroit.
In the closed intersection collision warning a blind corner separated the two vehicles and removed line-of-sight. This increases the potential danger, as the drivers can no longer see each other approach. It also makes the radio environment significantly more challenging. To provide a reliable wireless link the receiver must be robust to the combination of mobility and multipath reflections - a feature that is unique to the Cohda Radio.
The value of the Cohda Radio was clearly demonstrated for vehicle-to-vehicle safety applications. The Cohda Radio will allow DSRC to work in more places, more of the time, and will result in more lives saved.
