Abstract
A system includes a processor and a memory. The memory stores instructions executable by the processor to, upon determining that a first fluid level in a vehicle container is below a threshold based on fluid level sensor data, determine a second fluid level based on a fluid consumption signal and the fluid level sensor, and to navigate the vehicle based on the determined second fluid level.
Claims10
A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- upon determining that a first fluid level in a vehicle container is below a threshold based on fluid level sensor data,
- determine a leak in the container upon simultaneously determining a lack of fluid consumption and determining that the first fluid level in the container has changed from a first value above the threshold to a second value below the threshold and that a request for cleaning is deactivated;
- and
- navigate the vehicle based on the determined leak.
