System for collaborative blind spot mitigation
A system for collaborative blind spot mitigation is provided. The system includes a first vehicle including one or more sensors configured to provide visibility coverage around the first vehicle such that no blind spots exist in the visibility coverage. The system includes a second vehicle including one or more sensors configured to provide at least partial visibility coverage around the second vehicle. If a blind spot exists in the visibility coverage around the first vehicle upon operation failure of the one or more sensors of the first vehicle, data is collected from the one or more sensors of the second vehicle corresponding with visibility of the blind spot in the visibility coverage around the first vehicle and is used to supplement the data from the one or more sensors of the first vehicle to ensure that no blind spots exist in the visibility coverage around the first vehicle.
