Jaguar Land Rover has revealed that it is working on new technology for its cars. The company says it is working on ‘virtual windscreens’ and a new lighting and vehicle guidance system powered by lasers.
The company’s research engineer Paul Widdowson showed how JLR’s advanced work in using ‘structured light’ to both, project images onto the road surface and for mapping the topography rough ground ahead of the car, will work. JLR is experimenting with laser projections that will lay down a grid or box shape that’s the same width as the vehicle on the road surface a few metres ahead of the car. This would allow the driver to judge the car’s width with extreme accuracy, a very useful benefit on crowded city streets.
These laser projections could also be used to project animated arrows on the road surface, showing a vehicle’s intent to turn more clearly than easily obscured indicator units. The ‘structured lights’ could also be used for working out the depth of water the driver is about to wade through as well as mapping off-road surfaces ahead of a vehicle.
In theory, it could also be used on road surfaces to provide hyper-accurate information for an active suspension system. The accuracy of the information provided by laser projections also means that they can be used as safety sensors for parking or pedestrian avoidance. Perhaps the most radical use for the new laser technology is a replacement for conventional headlamp units. The light beams that are projected from tiny light units are easy to place accurately, allowing, for example, road edges to illuminate without using conventional high beams. Future laser headlamps could also be much small and less bulky than today’s units because the light is sent from the power units along a fibre optic cable, opening the way for a significant shift in car design. Reducing the bulk of the headlamp units could also improve pedestrian safety. Widdowson revealed that his team is already talking to suppliers about prototyping the idea and getting enough power for 2,500 Lumens in a package volume of around 0.5-litres.
The firm's new virtual windscreen technology enables various information to be projected on the screen, including sat-nav information, hazard warnings and most of the information that appears on conventional instrument packs. Unlike conventional head-up displays, which only project onto a small area of the windscreen, the JLR system uses the whole ‘screen as a head-up display. JLR engineers say that for track driving, the system could used to display correct racing lines and braking points and even show a virtual row of cones.
Also being worked on for the future are hand gesture controls – which JLR demonstrated for opening and closing a sunroof – and a 3D instrument cluster, which was particularly effective in sat-nav mode, showing a live 3D simulation of the immediate streetscape. JLR says future cars will also sync with the driver’s phone, using future appointments, traffic and weather reports to configure the car automatically. This could see a car being pre-warmed in cold weather, with the heated seats and steering wheel activating automatically. Individual driver preferences for driving position and entertainment sources will also be activated automatically. Future cars could also take into account the driver’s mood and wellbeing, using information from a smart watch or wristband.
