Important results from the project
The project aimed at fulfilling the following goals: 1. Development of a high-integrity safety monitoring concept for the supervision of automated functions. 2. Application topic related to the safe and efficient coordination of automated vehicles in confined sites. 3. The development of an industrial PhD student as part of the project.
Expected long term effects
The results of the project can be summarized as: 1. A novel safety supervisor architecture and method that monitors the automated driving functions and can intervene when necessary to ensure the safety of the automated driving function. The method is general, meaning that it can be applied to different automated driving functions. 2. Optimization-based methods for the safe and efficient coordination of automated vehicles in confined sites. The contributions in 1. and 2. aim at bridging the practical application and implementation of automated driving functions.
Approach and implementation
The safety monitoring concept is design to function with different automated driving functions. In terms of architecture it is below the automated driving function, i.e., it receives the input to the vehicle from the automated drivign function and determines if that input leads to safe behavior. In the cases it does not, the concept overwrites the input to the vehicle. The optimization-based coordination algorithm takes as input the vehicle routes and provides velocity profiles that the vehicles should follow such that safe and efficient behavior is achieved.
