Abstract
Systems, methods, and other embodiments described herein relate to sensing ingress of water in a vehicle. In one embodiment, a method includes acquiring, from a radar of a vehicle, radar data about a passenger cabin of the vehicle. The method includes determining a current state of the passenger cabin according to the radar data. The method includes, responsive to identifying that the current state indicates an ingress of water into the passenger cabin, generating a response to the ingress of the water.
Claims17
A monitoring system for improving safety of passengers by sensing an ingress of water into a vehicle, comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to:
- acquire, from a radar of the vehicle, radar data about a passenger cabin of the vehicle;
- determine a current state of the passenger cabin according to the radar data, including determining a height of water in the passenger cabin when present according to the radar data by identifying a presence of the water according to a signature embodied in the radar data and an extent of coverage of the water within the passenger cabin, the signature indicating a difference in density of a volume of the passenger cabin;
- and
- responsive to identifying that the current state indicates an ingress of the water into the passenger cabin, generate a response to the ingress of the water.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:
- acquire, from a radar of a vehicle, radar data about a passenger cabin of the vehicle;
- determine a current state of the passenger cabin according to the radar data, including determining a height of water in the passenger cabin when present according to the radar data by identifying a presence of the water according to a signature embodied in the radar data and an extent of coverage of the water within the passenger cabin, the signature indicating a difference in density of a volume of the passenger cabin;
- and
- responsive to identifying that the current state indicates an ingress of the water into the passenger cabin, generate a response to the ingress of the water.
