Warning indicator system and related methods
A method for warning approaching vehicles of an autonomous vehicle includes sensing a stopped condition of the autonomous vehicle, activating a warning indicator of the autonomous vehicle based on the stopped condition, sensing a start condition of the autonomous vehicle, and deactivating the warning indicator of the autonomous vehicle based on the start condition. The warning indicator includes a plurality of LEDs or an LED panel coupled to or formed within a sensor pod coupled to the autonomous vehicle.
1. A method for warning approaching vehicles of an autonomous vehicle, the method comprising:
sensing a stopped condition of the autonomous vehicle;
activating a warning indicator of the autonomous vehicle based on the stopped condition;
sensing a start condition of the autonomous vehicle; and
deactivating the warning indicator of the autonomous vehicle based on the start condition,
wherein the warning indicator comprises a plurality of LEDs or an LED panel coupled to or formed within a sensor pod coupled to the autonomous vehicle,
wherein activating the warning indicator comprises causing the plurality of LEDs or the LED panel to display one or more caret arrows oriented in a direction facing outward from the autonomous vehicle, and
wherein the one or more caret arrows comprises a plurality of caret arrows that increase in a size along a connecting assembly coupling the sensor pod to the autonomous vehicle and along a width of the sensor pod housing, wherein a first caret arrow at a location nearest to the autonomous vehicle is the smallest of all of the plurality of caret arrows and a second caret arrow at a location farthest from the autonomous vehicle is the largest of all of the plurality of caret arrows.
2. The method of claim 1 , wherein sensing a stopped condition of the autonomous vehicle comprises sensing the autonomous vehicle is stopped and is not driving, the sensing providing by one or more sensors associated with the sensor pod.
3. The method of claim 1 , wherein the sensor pod comprises a driver side sensor pod and a passenger side sensor pod, and wherein the warning indicator comprises a driver side warning indicator associated with the driver side sensor pod and a passenger side warning indicator associated with the passenger side sensor pod.
4. The method of claim 3 , wherein activating the warning indicator comprises simultaneously activating both the driver side warning indicator and the passenger side warning indicator.
5. The method of claim 3 , wherein deactivating the warning indicator comprises simultaneously deactivating both the driver side warning indicator and the passenger side warning indicator.
6. The method of claim 1 , wherein activating the warning indicator is continuous through an entirety of the stopped condition.
7. The method of claim 1 , wherein activating the warning indicator comprises activating a warning indicator on the sensor pod and on a connecting assembly coupling the sensor pod to the autonomous vehicle.
8. The method of claim 1 , wherein activating the warning indicator comprises turning on the plurality of LEDs or the LED panel.
9. The method of claim 1 , wherein deactivating the warning indicator comprises turning off the plurality of LEDs or the LED panel.
10. The method of claim 1 , wherein activating the warning indicator comprises causing the one or more caret arrows to progressively flash, to flash between on and off, to flash between different colors, to be constantly on, or any combination thereof.
11. The method of claim 1 , wherein activating the warning indicator comprises causing the one or more caret arrows to have a predetermined color pattern and a predetermined light effect, and wherein the predetermined color pattern and the predetermined light effect are based on a combination of the stopped condition of the autonomous vehicle and a sensed condition approaching traffic.
12. The method of claim 1 , wherein the one or more caret arrows comprises a plurality of caret arrows that are constant in size along a connecting assembly coupling the sensor pod to the autonomous vehicle and increase in a size along a width of the sensor pod housing.
13. The method of claim 1 , wherein the one or more caret arrows comprises a plurality of caret arrows that are constant in size along a connecting assembly coupling the sensor pod to the autonomous vehicle and along the sensor pod housing.
14. The method of claim 1 , wherein activating the warning indicator comprises causing the one or more caret arrows to progressively flash from a location nearest to the autonomous vehicle to a location farthest from the autonomous vehicle.
15. The method of claim 1 , wherein activating the warning indicator comprises causing the warning indicator to progressively flash, to flash between on and off, to flash between different colors, to be constantly on, or any combination thereof.
16. The method of claim 15 , wherein the warning indicator is configurated to have a predetermined color pattern and a predetermined light effect, and wherein the predetermined color pattern and the predetermined light effect are based on a combination of the stopped condition of the autonomous vehicle and the other vehicles and persons.
17. The method of claim 1 , further comprising sensing a location of approaching traffic or approaching persons with respect to the stopped autonomous vehicle.
18. The method of claim 17 , wherein the warning indicator comprises a plurality of warning indicators, the method further comprising selectively activating one or more of the plurality of warning indicators based on the sensed location of approaching traffic or approaching persons.
19. The method of claim 17 , wherein the sensor pod comprises a driver side sensor pod and a passenger side sensor pod, and wherein the warning indicator comprises a driver side warning indicator associated with the driver side sensor pod and a passenger side warning indicator associated with the passenger side sensor pod.
20. The method of claim 19 , wherein sensing determines the locating of approaching traffic or approaching persons is on the right, and the passenger side warning indicator is activated.
21. The method of claim 19 , wherein sensing determines the locating of approaching traffic or approaching persons is on the left, and the driver side warning indicator is activated.
22. The method of claim 19 , wherein sensing determines the locating of approaching traffic or approaching persons is on both the right and the left, and both the passenger side warning indicator and the driver side warning indicator are simultaneously activated.
23. The method of claim 17 , wherein the sensing the location of approaching traffic or approaching persons is continuous through an entirety of the stopped condition.
