A recently granted patent (Publication Number: US11922920B2) discloses a roof module for motor vehicles designed to be placed on vehicle roof side beams, forming part of the vehicle body shell. The roof module includes a roof skin with a smooth continuous surface and a roof substructure, along with features for autonomous or semi-autonomous driving. These features include at least one sensor module with environmental sensors, means for generating sound, and means for recording sound, all covered by the roof skin. The sound generation system is configured to provide audible signals to other road users, such as speech, standard driving sounds, motor sounds, and warning signals. The recording system is designed to detect traffic situations in collaboration with the autonomous driving controller and other vehicles based on their noise behavior.

Furthermore, the roof module incorporates a vibration generator as part of the sound generation system, which is coupled with the roof skin to produce audible vibrations outside the vehicle. This innovative technology aims to enhance communication with other road users and improve safety by detecting and responding to various traffic scenarios. The patent also covers the integration of acoustic insulation between the roof skin and a roof headliner to minimize sound transmission into the vehicle interior. The patent includes claims for different configurations of the roof module, including variations in the sound generation system and the use of vibration generators bonded under the roof skin, highlighting the versatility and adaptability of this technology for different vehicle types and applications.
