Challenges

Sensor Database for ADAS/AD Platform

Developing a sensor setup database for the ADAS/AD platform, reusable for various functions.

The main challenge was to build a sensor setup database that could be reused for different combinations of ADAS/AD functions ranging from SAE Level 0 to 4.

Requirements, Architectures, Database

Requirements, Architectures, Database

Define requirements, model architectures, create database. Our solution involved analyzing the previously created architecture for each function and defining the parameters affecting each function, such as braking distance or speed. Additionally, a series of calculations were performed, including reaction time and bus communication time between function elements (e.g., actuator, sensor), which contributed to the reaction time of the ego vehicle.

Concept Design & Idea Management

  • Analysis of the previously defined physical architecture for each function
  • Analysis of the functional and technical safety concept
  • Analysis of the hazard analysis and risk assessment

Implementation & Development

  • Creation and documentation of the Functional Architecture and Functional Requirements for the sensor setup
  • Creation and documentation of the Logical Architecture and Logical Requirements for the sensor setup
  • Creation and documentation of the Physical Architecture and Physical Requirements for the sensor setup
  • Creation and documentation of the Sensor Setup KPIs
  • Creation and documentation of various parameters affecting individual functions
  • Calculation and documentation of different parameters influencing each sensor
  • Calculation and documentation of different parameters influencing each sensor
  • Calculation and documentation of braking distance for each function
  • Creation of the sensor setup database

Results

Efficient Sensor Database for Driver Assistance Systems

Through our collaboration, we successfully created a sensor setup database where sensors can be selected based on the function or combination of functions being developed.

This approach enabled a high level of reusability for the sensor setup database and advanced research into extended driver assistance functions.
