摘要： Systems and techniques for detecting and locating low impact collisions, such as relatively low energy impact collisions involving an autonomous vehicle, are disclosed herein. Sensor data from audio sensors configured on a vehicle may be used to determine whether a threshold number of such sensors have detected sounds associated with a collision. Scores determined for the sensors based on audio energy and confidence values can be used to determine a location estimate for the detected collision.

摘要： Techniques for cleaning and calibrating a microphone are discussed herein. For example, a computing device can implement a microphone component to operate a speaker adjacent to a microphone to cause removal of an obstruction (e.g., rain, mud, dirt, dust, snow, ice, animal droppings, etc.) on or near the microphone. The microphone component can also or instead cause the speaker to output a frequency for testing operation of the microphone. By implementing the cleaning and/or calibrating techniques described herein, foreign particle(s) of varying size and type can be dislodged from an area near the microphone to improve performance of the microphone.

摘要： A vehicle computing system may implement techniques to emit warning sounds from a vehicle to notify other entities in an environment with the vehicle of the vehicle operation. A vehicle computing system may be configured to emit warning sounds based on a speed associated with the vehicle. The vehicle computing system may determine a planned vehicle trajectory and that a speed corresponding to the planned vehicle trajectory is associated with the warning sound emission. The vehicle computing system may determine a time that the vehicle will be at the speed and may emit the warning sound substantially at the time. In some examples, the vehicle computing system may emit a different sound prior to the time and may transition to the warning sound associated with the speed at the time. By warning other entities of the vehicle operation, the warning sound emission system may improve the safety of vehicle operation.
