Automakers have become more interested in developing autonomous cars. The acceptance rate of autonomous vehicles by customers is, however, limited. In view of the confidence that consumers embrace the autonomous cars is one of the key determinants. This paper therefore introduces Autocarreq. Mereq, an automated tool to generate trust requirements for self-sufficient cars. This automated tool uses the TReAC library to support capturing and checking accuracy occurring in autonomous car requirements. Autacarreq.Mereq tool which runs in table and mobile support, is compatible to minimise time for on-site capture and elicitation of trust requirements. This paper describes the Autocarreq.Mereq approach and demonstrates its use to capture and elicited trust requirements of autonomous car. © BEIESP.
