If the driver still does not show any reaction, the Cruising Chauffeur initiates the Minimum Risk Maneuver – which means that the computer either enters the emergency lane and brings the vehicle to a safe stop, or, if no emergency lane exists, it activates the hazard lights and stops where possible; if necessary it continues the ride at low (and decelerating) speed until it finds a suitable spot to stop.
The Minimum Risk Maneuver is also activated in the case of a technical failure. Towards this end, the software architecture provides for a monitoring level, the Safety Manager. This software identifies if one of the sensors fails and alerts the driver. In the meantime it can continue the driving task until the vehicle stops of the driver takes over. The Safety Manager software is based on the EB Tresos software framework from Elektrobit (EB).
