Abstract
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.
Claims21
A vehicle comprising:
- speakers positioned to play sound to an area external to the vehicle;
- a sensor not part of an acoustic vehicle alerting system;
- and
- the acoustic vehicle alerting system including a processor configured to:
- play a frequency on the speakers;
- evaluate feedback from the sensor to determine whether there is an error in the acoustic vehicle alerting system;
- and
- when there is the error, display an alert.
A vehicle comprising:
- speakers positioned to play sound to an area external to the vehicle;
- a wireless communication module to communicate with an external object that has a microphone;
- and
- an acoustic vehicle alerting system including a processor configured to:
- play a test frequency on the speakers;
- evaluate feedback from the external object to determine whether there is an error in the acoustic vehicle alerting system;
- and
- when there is the error, increase a volume of sound played by the speakers.
A vehicle comprising:
- speakers positioned to play sound to an area external to the vehicle;
- sensors not part of an acoustic vehicle alerting system;
- a dedicated short range communication module to communicate with an external object that has a microphone;
- and
- the acoustic vehicle alerting system including a processor configured to:
- play a test frequency on the speakers;
- receive feedback from the sensors and the external object;
- determine there is an error in the acoustic vehicle alerting system based on a majority of the feedback indicating that there is the error;
- and
- when there is the error, activate a diagnostic light.
