Abstract
An apparatus on a vehicle comprises one or more sensors, one or more nozzles that output fluid to clean the respective one or more sensors, and a compressor that generates fluid such as compressed air. The compressor is in fluid communication with the one or more nozzles. The apparatus further comprises one or more processors, and a memory storing instructions that, when executed by the one or more processors, cause the system to determine information of an acoustic emission from the compressor and to counteract the acoustic emission based on the determined information.
Claims17
An apparatus, comprising:
- a compressor configured to generate fluid, the compressor being in fluid communication with one or more nozzles;
- a reservoir disposed downstream of the compressor and fluidly connected to the compressor, the reservoir configured to store the fluid;
- one or more valves disposed downstream of the reservoir and fluidly connected to the reservoir, the one or more valves configured to regulate flow of the fluid;
- and
- the one or more nozzles disposed downstream of the one or more valves and fluidly connected to the one or more valves, the one or more nozzles configured to output the fluid to clean one or more sensors, and the one or more valves configured to open in response to an interior pressure inside the reservoir being within a threshold range and the one or more valves configured to close in response to the interior pressure being outside of the threshold range.
A method of controlling an operation of a compressor, comprising:
- generating, by a compressor, a fluid;
- storing, by a reservoir, the fluid generated by the compressor, wherein the reservoir is disposed downstream of the compressor and fluidly connected to the compressor;
- determining an interior pressure inside a reservoir and an expected pressure loss between the reservoir and one or more nozzles, wherein the one or more nozzles are disposed downstream of the reservoir;
- determining a first operation of a first valve disposed downstream of the reservoir and upstream of the nozzles, based on the interior pressure and an expected pressure loss between the reservoir and the nozzles;
- performing the first operation on the first valve;
- and
- controlling a second operation of a second valve based on an air quality index (AQI) at one of the one or more nozzles.
A method of controlling an operation of a compressor, comprising:
- generating, by a compressor, a fluid;
- storing, by a reservoir, the fluid generated by the compressor, wherein the reservoir is disposed downstream of the compressor and fluidly connected to the compressor;
- determining an interior pressure inside a reservoir and an expected pressure loss between the reservoir and one or more nozzles, wherein the nozzles are disposed downstream of the reservoir;
- determining an operation of a first valve disposed downstream of the reservoir and upstream of the nozzles, based on the interior pressure and an expected pressure loss between the reservoir and the nozzles, wherein the operation comprises opening the first valve in response to the interior pressure being within a threshold range and closing the first valve in response to the interior pressure being outside of the threshold range;
- and
- performing the operation on the first valve.
