Abstract
Devices 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.
Claims17
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 is 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;
- and
- in response to determining that the second parameter exceeds the second 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 is greater than 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;
- and
- iv. in response to determining that the second parameter exceeds the second threshold, send an alert message to the audio output device;
- wherein the automatic volume control trigger message comprises 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, 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 plurality of audio components for detecting ambient noise;
- and
- adjusting an audio output level of the audio output device based on the ambient noise.
