A system that projects the direction of travel onto the road ahead of self-driving vehicles to tell other road users what it is going to do next has been developed by Jaguar Land Rover.
The intelligent technology beams a series of projections onto the road to show the vehicle’s intentions – for example, stopping and turning left or right – as part of research into how people can develop their trust in autonomous technology.
The projections could even be used to share obstacle detection and journey updates with pedestrians, the company says.
They feature a series of lines or bars with adjustable spacing. The gaps shorten as the pod is preparing to brake before fully compressing at a stop. As the pod moves off and accelerates, the spacing between the lines extends. Upon approaching a turn, the bars fan out left or right to indicate direction.
Trials were set up by a team of advanced engineers, working in Jaguar Land Rover’s Future Mobility division, supported by cognitive psychologists, after studies showed 41% of drivers and pedestrians are worried about sharing the road with autonomous vehicles (AVs).
The innovative system was tested on a fabricated street scene at a Coventry facility with engineers recording trust levels reported by pedestrians both with and without projections.
The trust trial programme – which also included fitting of ‘virtual eyes’ to the intelligent pods in 2018 to see if making eye contact improved trust in the technology – was held as part of Jaguar Land Rover’s government-supported UK Autodrive project.
