TUNNEL DETECTION SYSTEM

A tunnel detection system includes an imager configured to capture image data and including a microcontroller, radar configured to capture radar data, and an ambient light sensor configured to capture light data. An electronic control unit (ECU) is communicatively coupled with each of the imager, the radar, and the ambient light sensor. The ECU includes data processing hardware that includes a tunnel detection application and a navigation application. The tunnel detection application is configured to compare an exposure value of the image data and a light value of the light data with the radar data to define tunnel data. The tunnel detection application is further configured to identify a tunnel based on the tunnel data.
