Hyundai Mobis develops Clusterless HUD

Hyundai Mobis has combined HUD and instrument cluster into one unit.

By Graeme Roberts

Hyundai Mobis has developed the claimed world’s first ‘Clusterless HUD’ which integrates the functions of the instrument cluster and the HUD (Heads-Up Display).

“Entering the era of full-scale electric vehicles, the utilisation of the interior space of the vehicle has become ever more important,” the supplier said in a statement. “As a response to this, [we have] proactively introduced new display technology which has been optimised for autonomous driving and electrification.”

The Clusterless HUD is a new cockpit technology which minimises driver distraction by distributing the various kinds of driving information displayed in the cluster to the HUD (Heads-Up Display) in front of the driver and AVNT (Audio, Video, Navigation and Telematics).

The Clusterless HUD is characterised by the fact that it raises the height of the driving information, which is required at all times, such as speed and RPM, to the driver’s eye level. In addition to the inherent driving assist functions of HUD, such as navigation, it is claimed to also greatly enhance safety and convenience. It is said to have differentiated the design and enhanced the visibility of the driving information display. Other auxiliary driving information is displayed through AVNT.

The Clusterless HUD is divided into four display areas, including three at the top and one at the bottom. The top display areas show the speed, RPM, ADAS-related information, and navigation information. The bottom display area shows basic vehicle information, such as the shift mode, temperature of the coolant, and distance to empty. It can also display the turn signal, system information and warning lights.

The HUD has a 15-inch display, providing a much larger display area than existing products. The company developed the new manufacturing technology for the combiner mirror, which implements HUD functions through the optical glass installed on the side of the dashboard, and the optical deposition specifications, thereby securing producibility. The frame fixed in the vehicle slopes towards the driver.

The Clusterless HUD will increase use of interior space. Currently, global automakers are focusing on securing interior space, such as enlarging the interior, by applying the platform exclusively for electric vehicles. The reduction in weight is expected to help increase range as well.

Hyundai Mobis has registered the clusterless HUD patent in countries including the US, China, and Germany, as well as in Korea. It is planning to preempt the new future of cockpit technology and try and win global orders through aggressive promotions targeting domestic and overseas automotive brands.
