Systems and methods for controlling an autonomous vehicle. One system includes an electronic processor and a memory configured to store a multi-layer grid and a multi-instanceable sensor plugin. The multi-layer grid includes information associated with positions in the environment. A plurality of sensors are configured to output sensor information. The electronic processor is configured to, for each of the plurality of sensors, determine a modality of the sensor and generate an instance of the sensor plugin based on the modality. The electronic processor receives, processes, and determines a plausibility of the sensor information. In response to determining that the sensor information is plausible, the electronic processor integrates the sensor information to the multi-layer grid. The electronic processor controls vehicle movement based on the multi-layer grid.

Sensor plugin architecture for grid map

Systems and methods for controlling an autonomous vehicle. One system includes an electronic processor and a sensor configured to detect a dynamic object in an environment. The electronic processor is configured to generate a dynamic object list including dynamic object information associated with the detected dynamic object. The electronic processor is also configured to receive a static occupancy grid including a plurality of cells storing occupancy information and occupancy probabilities associated with a static object in the environment. The electronic processor is further configured to superimpose the dynamic object information on the static occupancy grid, determine an overlap of the detected dynamic object and the static object, determine a dynamic object existence probability associated with the detected dynamic object based on the overlap, and classify the detected dynamic object as a ghost object based on the dynamic object existence probability.

Using static grid map to cross-check dynamic objects

Systems and methods for controlling an autonomous vehicle. One system includes an electronic processor and a memory configured to store an occupancy grid map. The occupancy grid map includes a set of cells associated with respective positions in an environment. A sensor is configured to output sensed occupancy information associated with positions in the environment. The electronic processor is configured to determine a position of the autonomous vehicle within the environment, and receive, from a server, a high density map. The high density map contains occupancy information. The electronic processor initializes the cells with occupancy information based on the high density map. The electronic processor confirms, based on the sensed occupancy information, a state of the set of the cells of the occupancy grid map, and controls vehicle movement based on the occupancy grid map.

Use of high density map in occupancy grid

Methods and systems for multi-hypothesis object tracking for automated driving systems. One system includes an electronic processor configured to receive environment information and generate pseudo-measurement data associated with an object within an environment of the vehicle. The electronic processor is also configured to determine, based on the environment information and the pseudo-measurement data, a set of association hypotheses regarding the object. The electronic processor is also configured to determine, based on the set of association hypotheses, an object state of the object. The electronic processor is also configured to control the vehicle based on the determined object state.

Multi-hypothesis object tracking for automated driving systems

A system for a reliability of objects for a driver assistance or automated driving of a vehicle includes a plurality of sensors that include one or more sensor modalities for providing sensor data for the objects. An electronic tracking unit is configured to receive the sensor data to determine a detection probability (p_D) for each of the plurality of sensors for each of the objects, to determine an existence probability (p_ex) for each of the plurality of sensors for each of the objects, and to provide vectors for each of the objects based on the existence probability (p_ex) for each contributing one of the plurality of sensors for the specific object. The vectors are provided by the electronic tracking unit for display as an object interface on a display device. The vectors are independent from the sensor data from the plurality of sensors.

Redundancy information for object interface for highly and fully automated driving

Redundant environment perception tracking for automated driving systems. One example embodiment provides a surveillance system, the system including a plurality of sensors, a memory, and an electronic processor. The electronic processor is configured to receive, from the plurality of sensors, environmental information of a common field of view, generate, based on the environmental information, a plurality of hypotheses regarding an object within the common field of view, the plurality of hypotheses including at least one set of hypotheses excluding the environmental information from at least one sensor of a first sensor type, determine, based on a subset of the plurality of hypotheses, an object state of the object, wherein the subset includes the at least one set of hypotheses excluding the environmental information from the at least one sensor of the first sensor type, and track the object based on the object state that is determined.

Methods and systems for controlling an autonomous vehicle. The method includes receiving sensor data from a plurality of sensors, determining, a plurality of probability hypotheses based upon the sensor data, and receiving metadata from at least one sensor of the plurality of sensors. An integrity level of at least one of the plurality of probability hypotheses is determined based upon the received metadata and at least one action is determined based upon the determined integrity level and at least one probability hypothesis of the plurality of probability hypotheses.
