Abstract
A sensor system includes a pump, a valve supplied from the pump, a sensor fixed relative to the pump, a nozzle supplied from the valve and aimed at the sensor, and a computer communicatively coupled to the pump, the valve, and the sensor. The computer is programmed to instruct the pump to operate; while the pump is operating, instruct the valve to close; receive data from the sensor while the pump is operating and the valve is instructed to be closed; and set a flag upon determining, based on the data received from the sensor, that the nozzle is outputting fluid onto the sensor.
Claims20
A system comprising:
- a pump;
- a valve supplied from the pump;
- a sensor fixed relative to the pump;
- a nozzle supplied from the valve and aimed at the sensor;
- and
- a computer communicatively coupled to the pump, the valve, and the sensor;
- wherein the computer is programmed to:
- instruct the pump to operate;
- while the pump is operating, instruct the valve to close;
- receive data from the sensor while the pump is operating and the valve is instructed to be closed;
- and
- set a flag upon determining, based on the data received from the sensor, that the nozzle is outputting fluid onto the sensor.
A computer comprising a processor and a memory storing instructions executable by the processor to:
- instruct a pump to operate;
- while the pump is operating, instruct a valve supplied from the pump to close;
- receive data from a sensor while the pump is operating and the valve is instructed to be closed;
- and
- set a flag upon determining, based on the data received from the sensor, that a nozzle supplied from the valve is outputting fluid onto the sensor.
A method comprising:
- instructing a pump to operate;
- while the pump is operating, instructing a valve supplied by the pump to close;
- receiving data from a sensor while the pump is operating and the valve is instructed to be closed;
- and
- setting a flag upon determining, based on the data received from the sensor, that a nozzle supplied from the valve is outputting fluid onto the sensor.
