Abstract
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.
Claims20
A computer-implemented method when executed by data processing hardware of a vehicle causes the data processing hardware to perform operations comprising:
- receiving radar data from a radar;
- receiving image data from an imager;
- receiving light data from an ambient light sensor;
- determining an exposure differential of the image data and a light differential of the light data;
- determining a preliminary tunnel detection indication based on the radar data, the exposure differential, and the light differential;
- receiving, from a navigation database of a server, one or more tunnel locations corresponding to a current location of the vehicle;
- based on the one or more tunnel locations, confirming the preliminary tunnel detection indication to identify a tunnel;
- and
- sending, to the server, an update indicating the identified tunnel for use by one or more third-party vehicles.
