Scenario aware perception system for an automated vehicle
A scenario aware perception system suitable for use on an automated vehicle includes a traffic-scenario detector, an object-detection device, and a controller. The traffic-scenario detector is used to detect a present-scenario experienced by a host-vehicle. The object-detection device is used to detect an object proximate to the host-vehicle. The controller is in communication with the traffic-scenario detector and the object-detection device. The controller configured to determine a preferred-algorithm used to identify the object. The preferred-algorithm is determined based on the present-scenario.
1. A scenario aware perception system suitable for use on an automated vehicle, said system comprising:
a traffic-scenario detector used to detect a present-scenario experienced by a host-vehicle;
an object-detection device that outputs a signal used to detect an object proximate to the host-vehicle; and
a controller in communication with the traffic-scenario detector and the object-detection device, said controller configured to select a preferred-algorithm from a plurality of optimized-algorithms, said preferred-algorithm used to process the signal from the object-detection device to identify the object, wherein the preferred-algorithm is selected based on the present-scenario.
2. The system in accordance with claim 1 , wherein the traffic-scenario detector includes a location-indicator, and the present-scenario is determined based on a map-location of the host-vehicle on a digital-map indicated by the location-indicator.
3. The system in accordance with claim 1 , wherein the traffic-scenario detector includes one or more of a camera, a lidar-unit, and a radar-sensor, and the present-scenario is determined based on a signal from the traffic-scenario detector.
4. The system in accordance with claim 1 , wherein the system includes a memory, and the controller is configured to select the present-scenario from a plurality of possible-scenarios stored in the memory.
5. The system in accordance with claim 1 , wherein the object-detection device includes one or more of a camera, a lidar-unit, and a radar-sensor, and the object is detected based on a signal from the object-detection device.
6. The system in accordance with claim 1 , wherein the controller is configured to further determine the preferred-algorithm based on an expected-direction of motion of the object relative to the host-vehicle indicated by the present-scenario.
