Self-driving car solutions company QCraft has unveiled the third generation of its Driven-by-QCraft hardware solution. It includes high-precision sensors with all-round visibility without blind spots, a computing platform, power and communication subsystems. System performance meets real-time requirements, and high reliability is ensured by redundancy of all components, including sensors.
The next generation Driven-by-QCraft is based on the Nvidia Drive Orin SoC. QCraft hopes that this will help accelerate the development and commercialization of a solution capable of reaching the L4 autonomous driving level.
The above complex of sensors can be easily installed and upgraded due to the modular design. It includes two main long-range lidars, three short-range lidars to cover blind spots (from 10 cm), four millimeter-wave radars, nine cameras and a combined inertial sensor.
The sensors are grouped into three groups. Even if one or two of them fail, the autonomous driving system can still ensure normal operation and allow the vehicle to stop safely.
The cameras operate in temperatures from -40 ° C to 125 ° C, and their lenses have a self-cleaning function that automatically removes condensation, dust and other contaminants.
The Driven-by-QCraft computing platform includes a central computing unit, a redundant computing unit and an on-board computing unit, which also allows you to safely park on the side of the road or brake even in an emergency situation.
QCraft currently has a fleet of approximately 100 autonomous vehicles of ten types, all equipped with the same hardware solution. These cars travel to ten cities in the United States and China. They are said to be able to autonomously cope with a variety of scenarios, including urban congestion, tunnels, difficult weather conditions, etc. In particular, in the Chinese cities of Suzhou, Shenzhen, Beijing, Wuhan, Wuxi and Chongqing, Longzhou ONE buses, the first model of robotic QCraft buses for public roads, making up the largest fleet of its kind in China.
