Abstract
Systems and methods for controlling audio output in a telematics system are provided. In on method a telematics device determines that a parameter has exceeded a first threshold and sends an automatic volume control trigger message to an audio output device. The telematics device determines that a second parameter has exceeded a second threshold and sends an alert message to the audio output device. The audio output device performs an automatic volume control procedure then plays back and audible alert message.
Claims16
A method in a telematics device coupled to a vehicle, the method comprising:
- determining that a first parameter of a first type exceeds a first threshold;
- in response to determining that the first parameter exceeds the first threshold, sending an automatic volume control trigger message to an audio output device coupled to the telematics device;
- determining that a second parameter of a second type exceeds a second threshold;
- in response to determining that the second parameter of the second type exceeds the second threshold, reading a second instance of the first parameter for determining that the first parameter has not dropped below the first threshold;
- and
- in response to determining that the second parameter exceeds the second threshold and determining that the first parameter has not dropped below the first threshold, sending an alert message to the audio output device;
- wherein sending the automatic volume control trigger message comprises sending a message that causes the audio output device to power up a plurality of audio components for detecting ambient noise.

A telematics device, comprising:
- a) a controller;
- b) an asset interface coupled to the controller;
- and
- c) a memory coupled to the controller, the memory storing machine-executable instructions which, when executed by the controller, configure the telematics device to:
- i. determine that a first parameter of a first type exceeds a first threshold;
- ii. in response to determining that the first parameter exceeds the first threshold, send an automatic volume control trigger message to an audio output device coupled to the telematics device;
- iii. determine that a second parameter of a second type exceeds a second threshold;
- iv. in response to determining that the second parameter of the second type exceeds the second threshold, read a second instance of the first parameter to determine that the first parameter has not dropped below the first threshold;
- and
- v. in response to determining that the second parameter exceeds the second threshold and determining that the first parameter has not dropped below the first threshold, send an alert message to the audio output device;
- wherein the machine-executable instructions which configure the telematics device to send the automatic volume control trigger message comprise machine-executable instructions which configure the telematics device to send a message that causes the audio output device to power up a plurality of audio components for detecting ambient noise.

A method in a telematics system including a telematics device and an audio output device coupled to the telematics device, the method comprising:
- determining, by the telematics device, that a first parameter of a first type exceeds a first threshold;
- in response to determining that the first parameter exceeds the first threshold, sending, by the telematics device, an automatic volume control trigger message to the audio output device;
- receiving the automatic volume control trigger message at the audio output device;
- invoking, at the audio output device, an automatic volume control procedure in response to receiving the automatic volume control trigger message;
- determining, by the telematics device, that a second parameter of a second type exceeds a second threshold;
- in response to determining that the second parameter exceeds the second threshold, read a second instance of the first parameter to determine that the first parameter has not dropped below the first threshold;
- and
- in response to determining that the second parameter exceeds the second threshold and determining that the first parameter has not dropped below the first threshold, sending, by the telematics device, an alert message to the audio output device;
- receiving the alert message at the audio output device;
- and
- playing, by the audio output device, an audible alert message based on the alert message;
- wherein invoking the automatic volume control procedure comprises powering up a microphone for detecting ambient noise and adjusting an audio output level of the audio output device based on the ambient noise.
