Drivers' acceptance of trajectory type in trajectory-driven Haptic Shared Control

Haptic shared control is a driving assistance system that allows for continuous communication between the driver and the automation through the steering wheel. Previous research has proposed the Four-Design-Choice-Architecture, a control system with a feedforward loop that opens possiblities for personalisation to the driver. The goal of this research is to understand how changing the reference trajectory and the feedforward gain influences the acceptance of the HSC. This investigation consists of an offline simulation platform and a human-in-the-loop experiment. The results showed that complete personalisation consistently leads to the lowest conflict times and torques for all drivers, however, drivers that adapt their driving style also reach low conflict values for the class-average guidance of their own class. The results also showed that a high feedforward gain of 0.92 is beneficial as it reduces conflicts up to 86.91% and is rated consistently higher in the CARS and Van der Laan questionnaires.
