Abstract
A system for safely operating an automated vehicle includes a first network including a sensor set comprising a plurality of sensors configured to detect the surroundings of the vehicle. The sensor set is coupled to a high-performance electronic control unit (ECU) configured to process the signals of the sensors for orientation, control, and collision avoidance. The system further includes a secure motion-control ECU redundantly coupled to at least one drive element via at least two control signals for controlling the vehicle. The high-performance ECU is configured to output an object recognition indicator signal for orientation, control, and collision avoidance to the motion-control ECU. The system also includes a second, hierarchical, redundant network for safely operating the vehicle. The motion-control ECU is designed to securely evaluate the signals of a human/remote-machine interface (HMI/RMI), a ground truth sensing device, and a perception-safety ECU for the recognition of an emergency state.
