Abstract
In one example, a method performed by a processing system of an autonomous vehicle includes controlling a sonar system of the autonomous vehicle to emit a plurality of sonar beams into an environment surrounding the autonomous vehicle, detecting a change in conditions in the environment, and adjusting, in response to the change in conditions, at least one of: a temporal parameter of the plurality of sonar beams or a spectral parameter of the plurality of sonar beams.
Claims19
A method, comprising:
- controlling, by a processing system of an autonomous vehicle, a sonar system of the autonomous vehicle to emit a plurality of sonar beams into an environment surrounding the autonomous vehicle;
- detecting, by the processing system, a change in conditions in the environment;
- and
- adjusting, by the processing system in response to the change in conditions, at least one of:
- a temporal parameter of the plurality of sonar beams or a spectral parameter of the plurality of sonar beams, wherein the spectral parameter comprises a spectral frequency of the plurality of sonar beams, and wherein the adjusting of the spectral parameter comprises:
- changing the spectral frequency from a constant frequency to a modulated frequency, or changing the spectral frequency from a modulated frequency to a constant frequency.
A method, comprising:
- controlling, by a processing system of an autonomous vehicle, a sonar system of the autonomous vehicle to emit a plurality of sonar beams into an environment surrounding the autonomous vehicle;
- detecting, by the processing system, a change in an internal condition of the autonomous vehicle;
- and
- adjusting, by the processing system in response to the change in the internal condition, at least one of:
- a temporal parameter of the plurality of sonar beams or a spectral parameter of the plurality of sonar beams, wherein the spectral parameter comprises a spectral frequency of the plurality of sonar beams, and wherein the adjusting of the spectral parameter comprises:
- changing the spectral frequency from a constant frequency to a modulated frequency, or changing the spectral frequency from a modulated frequency to a constant frequency.
A non-transitory computer-readable medium storing instructions which, when executed by a processing system of an autonomous vehicle, cause the processing system to perform operations, the operations comprising:
- controlling a sonar system of the autonomous vehicle to emit a plurality of sonar beams into an environment surrounding the autonomous vehicle;
- detecting a change in at least one of:
- conditions in the environment or an operating parameter of the autonomous vehicle;
- and
- adjusting, in response to the change, at least one of:
- a temporal parameter of the plurality of sonar beams or a spectral parameter of the plurality of sonar beams, wherein the spectral parameter comprises a spectral frequency of the plurality of sonar beams, and wherein the adjusting of the spectral parameter comprises:
- changing the spectral frequency from a constant frequency to a modulated frequency, or changing the spectral frequency from a modulated frequency to a constant frequency.
