Advancing the future.

Sensor Fusion in Autonomous Vehicles


Autonomous vehicles require precise synchronized timing for perception, localization and failsafe operation and control of critical subsystems

Sensor Fusion for Intelligent Control

  • Sensor fusion enables reliable and safe 360◦ sensing in autonomous vehicles

  • Advanced Driver Assistance System (ADAS) relies on precise synchronization for proper operation

  • Data from various sensors, video cameras and LIDAR/RADAR must be precisely timestamped


Precise in-vehicle synchronization makes it easier to meet Automotive Safety Integrity Level (ASIL-D) requirements


Complete In-vehicle Synchronization

  • GNSS-synchronized Time Base Master functions as a time reference to a time sub-domain in vehicles

  • Timing slaves that are embedded in Electronic Control Units (ECUs) enable precise time stamping of sensor data

  • Boundary Clocks serve as timing gateways between sub-domains

Enabling V2X Technology

  • Multiple, redundant synchronization options for continuous V2X communication in GNSS-challenged locations

  • Patented, self-healing algorithms augmented with standards-based protocols

Protempis products meet critical synchronization needs in autonomous vehicles

  • Time Sensitive Networks (TSN) ready

  • Protempis Grand Master for redundant fault tolerant time sync inside the vehicle

  • Resilient time sources in case of GNSS jamming
