The most sophisticated full self-driving computer produced by Tesla, Hardware 4 (HW4), has been cloaked in secrecy since its debut. Further information regarding HW4 has been revealed by renowned Tesla hacker @greentheonly, also known as Green, giving us important knowledge about its technology.
Camera Layouts with the 2-SOC Version
The shipping version of HW4, also known as the 2-SOC (System on a Chip) version, was found thanks to Green’s investigation of firmware samples. The present camera configuration and an enlarged one with additional surround-view cameras, such as a front bumper camera and two more side cameras, are both supported by this version. These cameras have a resolution of 2880×1876 and a frame rate of up to 45 fps. The vendor for the primary and backup cameras has not yet been chosen, and each has distinct specs.
According to reports, the Teseo V platform underpins the new Global Navigation Satellite System (GNSS), while the radar system links through Ethernet and uses the internal IP address 192.168.90.110 to function.
New cameras and first HW4 camera connectors
Green first unveiled HW4 with 12 camera ports, and it was anticipated that HW4 cars would use new cameras. The Model S and Model X, which were the first vehicles to use HW4, feature the new hardware but not the new cameras. The bumper will get a new camera, and there will be one more on either side of the car, as previously mentioned in the Project Highland story.
The 3-SOC Version and two HW4 setups
Two HW4 configurations are depicted in Green’s most recent research: one with extra cameras, the other without. Moreover, Green’s research of the firmware has revealed that a 3-SOC version is in existence and under development. The core deserializing routing for this version is different, but the camera layouts are the same. It’s possible that the GPU in HW4 has been constrained by increased heat production. The 3-SOC version might be able to solve this problem by enabling new hardware or by providing greater heat dissipation. At this point, it’s unclear exactly why the 3-SOC version was created or how it functions.
Discoveries Associated with Tesla Semi Trucks
Another noteworthy revelation involved information connected to Tesla’s truck, with the battery-management system (BMS) and all three subpacks reachable via an internal ethernet network, which was disclosed through Green’s firmware research.
These findings by @greentheonly offer a thorough comprehension of the cutting-edge technology underlying Tesla’s HW4. Its prospective uses and capabilities are surely interesting for the car industry and customers as the most sophisticated fully autonomous computer on the market.
It is critical to address concerns about the technology’s safety, functionality, and interoperability with current systems as Tesla keeps working to create and improve its full self-driving technology. The cutting-edge HW4 and the automated driving environment it promises to provide are eagerly awaited by the world.
