Modern assistance systems and driver monitoring are to become cheaper, more energy-efficient and smaller. This is what the three companies Ambarella, Autobrains and Seeing Machines want to achieve with their cooperation.

Cameras are of central importance as sensors for the automation of driving functions and the driver monitoring that will be mandatory in the future. For reasons of cost and simplification, it makes sense to bundle as much of this technology as possible: for example cameras for monitoring the space in front of the vehicle, the camera for monitoring the driver's attention and the associated electronics. One challenge here is the heat generated by the current flow when the algorithms in the chips are doing their work.
Ambarella, Autobrains and Seeing Machines want to solve this problem together by combining special algorithms for artificial intelligence from Autobrains and Seeing Machines with hardware from Ambarella to create a very energy-saving system-on-chip. The entire system, according to Autobrains, completes its tasks with only a tenth of the computing power (and currents) that conventional solutions would require. So it saves energy, generates less heat and is smaller because less hardware power is required.
According to the companies, the front camera, the driver monitoring camera and the electronics can be housed together in one housing. That would be difficult with conventional systems because too much heat is produced in a small space. In addition, the system can also be placed in the two places that are actually predestined for it: on the dashboard or in the base of the interior mirror. In addition to the heat produced by the electronics itself, there is also solar radiation.
The joint development of the three companies includes Seeing Machines' e-DME (Driver Monitoring Engine) software stack, Autobrains' AI software stack and Ambarella's hardware: the Ambarella CV2FS/CV22FS AI Perception SoC, which the company claims to offer the highest AI performance per watt in the industry. The overall solution is both flexible and easily scalable and can therefore be adapted to different vehicles.
BMW i Ventures, VinFast, Continental and Knorr-Bremse, among others, are involved in the Israeli start-up Autobrains. Continental is already working with the US chip manufacturer Ambarella on the topic of autonomous driving.
