Validation methodology of different driver monitoring systems using a modular motion drive simulator

In India, Driver Drowsiness and Attention Warning (DDAW) system market is increasing due to anticipation on mandatory regulation for DDAW. However, readiness of the solution to introduce to Indian consumer can be challenging as the validations to meet standard (Automotive Industry Standard 184) for the system are complex and sometimes subjective in nature. Furthermore, the evaluation procedure to map the system accuracy with the Karolinska sleepiness scale (KSS) requirement involves manual interpretation which can lead to false reading. In certain scenarios, KSS validation may entail to fatal risks also. Currently, there is no effective mechanism so far available to compare the performance of different DDAW systems which are coming up in Indian market. This lack of comparative investigation channel can be concerning factor for the automotive manufactures as well as for the end-customers. In this paper, a robust validation setup using motion drive simulator with 3 degree of freedom (DOF) is proposed to overcome shortcoming of existing KSS validation procedure. Moreover, designing and testing methodology are explained in stage-by-stage approach. In addition, this study details on integration of multiple DDAW technologies and real time testing of those solutions under simulated road scenario. Thereby, data of multiple driving behavior are fetched to analyze drowsiness pattern and performance comparison study.
