1. A method performed by a control unit for handling safe stop mode of a vehicle in autonomous mode, wherein the method comprises:
obtaining, from an inside input device being activated by a user, wherein the inside input device is located inside the vehicle, an activation request for activating the safe stop mode, wherein the vehicle cannot perform autonomous driving when the safe stop mode is activated, and wherein the autonomous mode is enabled at the same time as the safe stop mode is activated;
when the activation request has been obtained, verifying that all safety conditions of the vehicle are fulfilled, wherein the fulfilled safety conditions indicates that the vehicle cannot move;
activating the safe stop mode when the activation request has been obtained and when all safety conditions are fulfilled, wherein the activating the safe stop mode comprises disconnection of communication between the vehicle and an autonomous system comprised in the vehicle;
triggering at least one light source located on the outside of the vehicle to be turned on when all safety conditions are fulfilled;
after the safe stop mode has been activated, obtaining, from an outside input device being activated by the user, an inactivation request for inactivating the safe stop mode of the vehicle, wherein the outside input device is located on the outside of the vehicle; and
inactivating the safe stop mode of the vehicle when the inactivation request has been obtained, wherein the vehicle can perform autonomous driving when the safe stop mode is inactivated.
