Photo: Quectel
The Proactive Security Solution for Intelligent Driving will enhance safety by supporting ADAS and driver monitoring systems (DMS). It integrates Quectel multi-mode LTE Cat 6 smart modules SC600Y/SC600T and an artificial intelligence (AI) algorithm from a third party to realize ADAS and DMS capabilities including monitoring irregular driving behaviors, conducting precise detection of vehicles and traffic signs, sending warnings of potential risks and more. For ADAS, it can precisely identify and locate vehicles, pedestrians, lanes and traffic signs and will send alerts to drivers if an imminent collision or an unintended lane departure is detected. The DMS supports facial recognition and detection, and is able to monitor driver attentiveness and measure eye blinks as well as head movements so that drivers will receive warnings of distractions, smoking, yawning or looking around.

The ZED-F9K GNSS and dead-reckoning module brings continuous lane-accurate positioning to challenging urban environments. Building on the F9 platform, the module offers both high-precision multi-band GNSS and inertial sensors. It combines the latest generation of GNSS receiver technology, signal processing algorithms and correction services to deliver down to decimeter-level accuracy within seconds. The real-time kinematic (RTK) receiver module receives GNSS signals from all orbiting constellations. The inertial sensors constantly monitor changes in the moving vehicle’s trajectory and continue to deliver lane-accurate positioning when satellite signals are obstructed, such as in parking garages, tunnels, urban canyons or forested areas. The module’s accuracy and low latency make it suitable for automotive OEMs and Tier 1 automakers developing V2X (vehicle-to-everything) communication systems. By continuously sharing their location, V2X systems help increase overall road safety and reduce congestion.
