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 – which are projected from tiny light units - are easy to place accurately, allowing, for example, road edges to illuminated without using a conventional high beams.
Because the light is sent from the power units along a fibre optic cable, future laser headlamps could be much small and less bulky than today’s units, opening the way for a significant shift in car design. Reducing the bulk of 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 2500 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 particular 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.
