The pedestrian protection system may also include an external airbag system that deploys an external airbag outside of the vehicle. In operation, a processor receives the first signal from the first sensor, processes the first signal to detect the hazard condition, and activates the external airbag system in response to the detected hazard condition to protect at least one of a pedestrian and the vehicle. ## Claims ### Claim 1 A pedestrian protection system, comprising: a first sensor configured to generate a first signal indicating an object is detected; an external airbag system comprising a first external airbag coupled to a vehicle on a first side of a wheel well, wherein the external airbag system is configured to deploy the first external airbag to block an object from entering the predicted tire path of movement between a surface below the vehicle tire and a bottom surface of the vehicle; and a processor configured to: receive the first signal from the first sensor, process the first signal to determine the object is in a predicted tire path of a tire of the vehicle, and in response to determining the object is in the predicted tire path of the tire of the vehicle, activate the external airbag system to move the object out of the predicted tire path of movement and/or block an object from entering the predicted tire path. ### Claim 2 (depends on 1) The system of claim 1, comprising a second external airbag coupled to the vehicle on a second side of the wheel well, wherein the first side and the second side are on opposites sides on the wheel well. ### Claim 3 (depends on 1) The system of claim 1, wherein the first sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor. ### Claim 4 (depends on 1) The system of claim 1, comprising a second sensor configured to generate a second signal indicating a hazard condition, wherein the processor cross-references the first signal and the second signal to verify the hazard condition. ### Claim 5 (depends on 4) The system of claim 4, wherein the second sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor. ### Claim 6 (depends on 1) The system of claim 1, wherein the external airbag system includes a first retraction system that retracts the first external airbag after deployment for reuse. ### Claim 7 A method for deploying a pedestrian protection system, the method being implemented by a processor configured to execute computer programs, and the method comprising: receiving a first signal from a first sensor, the first signal indicating an object is detected; processing the first signal to determine the object is in a first predicted tire path of a tire of a vehicle between a surface below the tire and a bottom surface of the vehicle; in response to determining the object is in a first predicted tire path of a tire of a vehicle between a surface below the tire and a bottom surface of the vehicle, activating an external airbag system to deploy a first external airbag on a first side of a wheel well to move the object out of the first predicted tire path of movement and/or block an object from entering the first predicted tire path of movement. ### Claim 8 (depends on 7) The method of claim 7, comprising a second external airbag coupled to the vehicle on a second side of the wheel well, wherein the first side and the second side are on opposites sides on the wheel well. ### Claim 9 (depends on 7) The method of claim 7, wherein the first predicted tire path of movement is in a forward direction of travel. ### Claim 10 (depends on 7) The method of claim 7, comprising receiving a second signal from a second sensor, the second signal indicating a hazard condition in the first predicted tire path of movement. ### Claim 11 (depends on 9) The method of claim 9, detecting the hazard condition in the first predicted tire path of movement in response to the second signal. ### Claim 12 (depends on 11) The method of claim 11, comprising cross-referencing the first signal and the second signal to verify the hazard condition. ### Claim 13 A vehicle pedestrian protection system, comprising: a vehicle; a first sensor configured to generate a first signal indicating an object is detected; an external airbag system comprising a first external airbag coupled to a vehicle on a first side of a wheel well, wherein the external airbag system is configured to deploy the first external airbag to block an object from entering the predicted tire path of movement between a surface below the vehicle tire and a bottom surface of the vehicle; and a processor configured to: receive the first signal from the first sensor, process the first signal to determine the object is in a predicted tire path of a tire of the vehicle, and in response to determining the object is in the predicted tire path of the tire of the vehicle, activate the external airbag system to move the object out of the predicted tire path of movement and/or block an object from entering the predicted tire path. ### Claim 14 (depends on 13) The system of claim 13, comprising a second external airbag coupled to the vehicle on a second side of the wheel well, wherein the first side and the second side are on opposites sides on the wheel well.
