Hyundai Mobis develops new lighting and moving grille technology

Hyundai Mobis is promoting new 'lighting grille' technology, which implements an LED lighting function right in front grille of a car. The company says it will help determine the very first impression, and also integrate another new 'grille integral active air flap' technology.

The company said hello completed captured the development of we've got the technology, the result of its R&D efforts in reaction to the megatrends of electric vehicles and autonomous vehicles. It's now verifying its reliability for commercialisation. Mass production is slated for the coming year. The core of the new grille technology includes the 'lighting grille' and the 'moving grille.' Over the years, the automotive grille has been regarded as a vent for cooling the engine so that as a design element that determines the very first impression from the vehicle. However, with EVs gaining ground recently, the existing grille is being transformed to have different uses including lighting systems, sound systems and displays.
While using grille like a lighting device Hyundai Mobis' 'lighting grille' technology can use the whole front grille from the car as a lighting device. It is characterised when you are able to implement various scenarios like the autonomous driving mode, the EV charging mode, the welcome light function, the sound beat display, as well as an emergency warning light display.

The 'lighting grille' can be used as a means of emailing other vehicles or pedestrians also it can also create strong and different design effects, depending on how the sunlight patterns are applied.

The 'moving grille' technology, also developed by Hyundai Mobis, automatically controls the exterior air for cooling the engine as the grille moves and provides the sunlight work as well. Unlike the existing method (built-in), as this has been developed as a grille integral type (external), it's expected to not just improve fuel efficiency and lower exhaust gas, but additionally realise a feeling of luxury in the exterior design of the automobile. The built-in air flap, located insidem the automotive grille, detects changes in the temperature of the coolant and blocks the inflow of outside air by decreasing the flap if cooling is not required.

If this product is used to a vehicle, it may improve fuel efficiency because it reduces air resistance (if outside air is blocked) and reduce the emission of pollutants with the exhaust gas by increasing the cooling efficiency within the engine room. The advantage of the grille integral (external) air flap is it can use differentiated design patterns through its lighting whilst enhancing the eco-friendly effect. \”We are making constant efforts to build up new technologies that can meet customer needs in reaction to the alterations in future car trends,\” Lee Woo-il, head of the Module Lab of Hyundai Mobis, said.

\”We will preempt the worldwide market with innovative products that combine an advanced of technology readiness with emotional quality\” he added.

Last year Hyundai Mobis developed a virtual engine sound system that utilizes the automotive grille as a global first. If this technologies are applied to vehicles, it can be used not only for that virtual engine sound, but additionally as the turn signal sound, the electrical Vehicle charging alarm sound, and speakers for enjoying music while camping, the company said.
