Methods to Enable A Driver Messenger System for Lane Change Assistance Application

  • Driver messenger system (DMS) conveys scenario-specific messages to nearby vehicles
  • Offers safer driving by assisting connected and autonomous vehicles in situational awareness
  • Flexible application designed to run in various computer system environments without compromising any major functionality


Researchers at the University of Central Florida and Honda Research Institute, USA have developed a communication technology that can help drivers avoid road accidents and improve their short-term and long-term driving decisions. With the new point-to-point Driver Messenger System (DMS), connected and autonomous vehicles can communicate with each other, assisting with situational awareness and a safer driving experience. The system maintains a local object map of a host vehicle (HV) and uses it to convey scenario-specific, personalized messages to nearby identified target vehicles (TVs) based on a list of pre-defined common traffic scenarios. Example scenarios include lane changes, slow traffic ahead, tailgating and curved roads. Personalized messages based on vehicle connectivity can be used to connect drivers and avoid potential on-road misunderstandings and conflicts, thereby directly or indirectly improving road safety.

Technical Details

The DMS invention is a computer device with at least one processor and one memory device. It comprises four main modules: local object map, automatic scenario detection, target recognition, and Vehicle-to-Everything (V2X) communications. Associated with a host vehicle (HV), the device is programmed to do the following:
Receive sensor information from one or more sensors (such as front and back radars and cameras) associated with the HV
Build and update a local object map of the HV surroundings based on the sensor information and Basic Safety Messages received from nearby vehicles
Detect a driving scenario (pre-defined) based on the local object map
Determine target vehicles (TVs) that will be affected by the detected driving scenario
Transmit one or more personalized Driver Intent Messages (DIMs) to the target vehicle(s) about the detected driving scenario
In one example application, the invention framework is embedded within a vehicle’s onboard unit (OBU) to inform TVs about the HV’s intentions, such as a lane change.

Stage of Development

Prototype available.



  • DMS framework can act as an advanced safety feature/warning system by providing extra time for headway and overall distance measurement between the HV and TVs.
  • Can be used in real-life straight and curved roads on highways and urban roads

Potential Applications

  • Automotive industry
