A driving analysis server may be configured to receive vehicle operation data from vehicle sensors, and may use the data to identify a potentially high-risk or unsafe driving event by the vehicle. The driving analysis server also may receive corresponding image data, video, or object proximity data from the vehicle or one or more other data sources, and may use the image, video, or proximity data to analyze the potentially high-risk or unsafe driving event. A driver score for the vehicle or driver may be calculated or adjusted based on the analysis of the data and the determination of one or more causes of the driving event. |

1. A driving analysis device comprising:
a processing unit comprising a processor; and a memory unit storing computer-executable instructions, which when executed by the processing unit, cause the driving analysis device to:
receive a driver score associated with a driver of a first vehicle;receive first vehicle driving data collected by vehicle operation sensors within the first vehicle, wherein the driving analysis device is located on the first vehicle;identify an occurrence of sudden braking by the first vehicle, swerving by the first vehicle, or an impact by the first vehicle, based on the first vehicle driving data;in response to identifying the occurrence of sudden braking, swerving, or impact, analyze at least one of image data, video data, or object proximity data associated with the occurrence of sudden braking, swerving, or impact by the first vehicle; andidentify at least two causes of the occurrence of sudden braking, swerving, or impact by the first vehicle, wherein identifying the at least two causes comprises:
attempting to identify at least two external causes of the occurrence of sudden braking, swerving, or impact by the first vehicle by analyzing at least one of the image data, video data, or object proximity data;if at least two external causes can be identified:
identifying a first external cause and a second external cause;based on the analysis of the at least one of image data, video data, or object proximity data associated with the occurrence of sudden braking, swerving, or impact by the first vehicle, determining a percentage of cause associated with each of the first external cause and the second external cause;evaluating the determined percentage of cause of the first external cause and the second external cause to identify one of the first external cause and the second external cause as a primary cause, the primary cause being the cause having a percentage greater than a predetermined event cause threshold;determining whether the primary cause was unsafe or high-risk driving;responsive to determining that the primary cause was unsafe or high-risk driving, adjusting the driver score;responsive to determining that the primary cause was not unsafe or high-risk driving, maintaining the driver score based on the occurrence of sudden braking, swerving or impact by the first vehicle; andif at least two external causes cannot be identified, determining that high-risk or unsafe driving by the driver of the first vehicle was the cause of the occurrence of sudden braking, swerving, or impact by the first vehicle and adjusting the driver score based on the at least two external causes not being identified. |
