Karma’s new L4 E-Flex Van is powered by the NVIDIA DRIVE AGX Pegasus™ autonomous vehicle computing platform, which achieves an unprecedented 320 trillion operations per second of deep learning. It’s built on a scalable architecture, with two NVIDIA Xavier™ processors and two Tensor Core GPUs. This energy-efficient, high-performance AI computer runs an array of deep neural networks simultaneously for safe, highly automated and fully autonomous driving. The L4 van’s software platform and sensors suite are supported by WeRide, which covers full 360-degree FoV (Field of View) and provides precise, real-time localizations powered by multiple sensors including LiDar, radar, camera, GNSS and INS.
The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries.
In North America, GM EVs will be powered by rectangular, pouch-style battery packs that are simple, lightweight and space-efficient.
GM’s ability to stack batteries vertically is unique in the industry and it allows for a flat cabin floor and more interior room than comparable EVs that use cylindrical battery packs.
The pack also allows engineers to deliver vehicles with an optimized weight distribution and a lower center of gravity to improve ride and handling.
The basic aim of DHT technology for cost-effective PHEVs is to permit the design of very compact automatic transmissions with an integrated high-voltage electric motor on the output side of the transmission. The Vitesco Technologies cost-effective PHEV prototype offers the driver the same standard of comfortable driving and shifting that until now has been associated with plug-in hybrids equipped with a conventional 6-speed automatic transmission. And yet a DHT transmission with Vitesco technology has only four mechanical gears and has no mechanical synchromesh systems, auxiliary hydraulics or start clutch. Moving off (in 1st and 2nd gear) and reversing are handled by the electric drive motor, while synchronization is performed by a starter-alternator that also provides fast and smooth starting of the internal combustion engine.
Drivers can use this technology to adjust seven performance features including the maximum torque output of the motor, ignition, acceleration and deceleration abilities, regenerative braking capacity, maximum speed limit, responsiveness, and energy use on climate control.
The application provides optimized settings for a designated destination by analyzing the remaining distance and electric energy requirement. It can also accommodate sportier driving by recommending tailored performance settings.
