Diagnosis of an acoustic vehicle alerting system (AVAS) based on existing sensors

摘要

Method and apparatus are disclosed for an acoustic vehicle altering system (AVAS) based on existing sensors. An example vehicle includes speakers, sensors, and an acoustic vehicle alerting system. The speakers are positioned to play sound to an area external to the vehicle. The sensor is not part of an acoustic vehicle alerting system. Additionally, the acoustic vehicle alerting system plays a test frequency on the speakers, evaluates feedback from the sensor to determine whether there is an error in the acoustic vehicle alerting system, and when there is an error, displays an alert.
