Validation of critical maneuvers based on shared control

This paper presents the validation of shared control strategies for critical maneuvers in automated driving systems. Shared control involves collaboration between the driver and automation, allowing both parties to actively engage and cooperate at different levels of the driving task. The involvement of the driver adds complexity to the control loop, necessitating comprehensive validation methodologies. The proposed approach focuses on two critical maneuvers: overtaking in low visibility scenarios and lateral evasive actions. A modular architecture with an arbitration module and shared control algorithms is implemented, primarily focusing on the lateral control of the vehicle. The validation is conducted using a dynamic simulator, involving 8 real drivers interacting with a virtual environment. The results demonstrate improved safety and user acceptance, indicating the effectiveness of the shared control strategies in comparison with no shared-control support. Future work involves implementing shared control in drive-by-wire systems to enhance safety and driver comfort during critical maneuvers. Overall, this research contributes to the development and validation of shared control approaches in automated driving systems.
