Calling all cars

DaimlerChrysler has developed a wireless car-to-car communications system that can relay warnings about road conditions, improving traffic flow and enhancing safety.

A demonstration using a Mercedes-Benz E-Class and a Dodge Durango was presented at the company’s Innovation Symposium in Washington this month.

The Dedicated Short-Range Communication (DSRC) system uses a 5.9 GHz wireless local area network (WLAN) connection.

Cars pass information to roadside communications stations and from vehicle to vehicle up to a distance of 1,000m, and can also transmit digital music or map updates.

DaimlerChrysler is working with the US Federal Department of Transport and the states of Florida, Michigan and California to prepare further tests for later this year.

‘The technology will be fully mature in the next two years,’ said Chris Wilson, vice-president of ITS strategy and programs for Daimler- Chrysler Research and Technology, North America.

‘It needs to reach a critical mass to be effective so we are in discussion with other car companies and the government.’
