Volvo reveals hi-tech bicycle helmet that warns cars

There may finally be a solution to keeping cyclists and cars safe while sharing the road, using a hi-tech helmet and an internet 'cloud'.

Volvo has invented a hi-tech bicycle helmet that aims to keep cars a safe distance away from cyclists while sharing the road.

The Swedish car maker has unveiled a helmet that uses Bluetooth technology to 'talk' to your phone, which in turns sends the cyclist's exact location and speed to an internet cloud.

That information can then be shared with cars using the same cloud-based data – and the system can even be reversed, so that cyclists can be warned about nearby cars.

The hi-tech helmet was unveiled at the Geneva motor show overnight and was a joint venture between Volvo, helmet maker Poc and technology company Ericsson.

The helmet that beams information to outer space is still many years away from becoming a reality, but Volvo technology expert Fredrik Marthinsson says the company is "exploring every available option".

"We know we have, in theory, the technology to do this right now," said Mr Marthinsson.

"But it's dependent on so many things. First we need the technology in the helmet and then for cars to share the same information network over an internet cloud."

Almost 100 cyclists have been killed on Australian roads over the past two years

He said it is Volvo's "vision" to have such a solution to cyclist safety in the near future.

Almost 100 cyclists have been killed on Australian roads over the past two years, compared to 67 cyclist fatalities in the two years prior, figures from the Federal Government show.

The hi-tech helmet is an extension of the "car to car" and "car to infrastructure" technology unveiled by Volvo earlier this year.

In the meantime, Volvo has recently upgraded its "City Safety" laser and radar system which can now detect pedestrians and cyclists, as well as cars.

The technology was originally introduced in 2009 to stop rear-end crashes in slow-moving traffic but has since been modified to detect other road users.
