Automated vehicle control strategy for pedestrian crowds
A system for operating an automated vehicle in a crowd of pedestrians includes an object-detector, optionally, a signal detector, and a controller. The object-detector detects pedestrians proximate to a host-vehicle. The signal-detector detects a signal-state displayed by a traffic-signal that displays a stop-state that indicates when the host-vehicle should stop so the pedestrians can cross in front of the host-vehicle, and displays a go-state that indicates when the pedestrians should stop passing in front of the host-vehicle so that the host-vehicle can go forward. The controller is in control of movement of the host-vehicle and in communication with the object-detector and the signal-detector. The controller operates the host-vehicle to stop the host-vehicle when the stop-state is displayed, and operates the host-vehicle to creep-forward after a wait-interval after the traffic-signal changes to the go-state when the pedestrians fail to stop passing in front of the host-vehicle.
1. A system for operating an automated vehicle in a crowd of pedestrians, said system comprising:
an object-detector that detects pedestrians proximate to a host-vehicle; and
a controller in control of movement of the host-vehicle and in communication with the object-detector, said controller operates the host-vehicle to stop the host-vehicle when pedestrians pass in front of the host-vehicle, and operates the host-vehicle to creep-forward after a wait-interval when the pedestrians continue to pass in front of the host-vehicle.
2. The system in accordance with claim 1 , wherein the system includes a warning-device detectable by the pedestrians, said warning-device activated when the controller operates the host-vehicle to creep-forward.
3. The system in accordance with claim 2 , wherein the warning-device is an acoustic-transducer that emits an audible beep when activated.
4. The system in accordance with claim 2 , wherein the warning-device is a light-source that emits a flashing-light when activated.
5. A system for operating an automated vehicle in a crowd of pedestrians, said system comprising:
an object-detector that detects pedestrians proximate to a host-vehicle;
a signal-detector that detects a signal-state displayed by a traffic-signal, wherein the traffic-signal displays a stop-state that indicates when the host-vehicle should stop so the pedestrians can cross in front of the host-vehicle, and displays a go-state that indicates when the pedestrians should stop passing in front of the host-vehicle so that the host-vehicle can go forward on a path that is free from pedestrians; and
a controller in control of movement of the host-vehicle and in communication with the object-detector and the signal-detector, said controller operates the host-vehicle to stop the host-vehicle when the stop-state is displayed, and operates the host-vehicle to creep-forward after a wait-interval after the traffic-signal changes to the go-state when the pedestrians fail to stop passing in front of the host-vehicle.
6. The system in accordance with claim 5 , wherein the system includes a warning-device detectable by the pedestrians, said warning-device activated when the controller operates the host-vehicle to creep-forward.
7. The system in accordance with claim 6 , wherein the warning-device is an acoustic-transducer that emits an audible beep when activated.
8. The system in accordance with claim 6 , wherein the warning-device is a light-source that emits a flashing-light when activated.
