People use their eyes and ears to pick up on traffic situations involving potential hazards. For self-driving vehicles to do the same thing, they need a whole host of sensors. As the number of sensors they contain increases, however, so too does the amount of space required to fit them in – something that is often incompatible with the vision of designers. Now, researchers at the Fraunhofer-Gesellschaft have discovered a method of integrating certain sensors discreetly. Their solution lies in the vehicle’s headlights, where they are combining optical light, radar and LiDAR.

Today’s vehicles are able to take on more and more functions themselves without requiring the driver’s input. Cruise control automatically maintains the right distance from the car in front, lane departure warning systems correct the vehicle’s path if necessary and emergency braking kicks in if the driver is caught off guard.

All this is possible thanks to cameras in the passenger area and Radar sensors in the radiator grill – and the future is set to see cars do even more by themselves. Making this happen means using significantly more sensors, but cramming grills full of them isn’t something that car designers are keen to entertain.
