Automatic variable radio volume control system
First Claim
1. An automatic variable radio volume control system for a vehicle, they system comprising:
- at least one module including microprocessor means for controlling and monitoring a utility of the vehicle and sending informational signals about the controlling of said utility;
a vehicle multiplex bus coupled to said at least one module for transferring said informational signals over said multiplex bus;
programmable computer means coupled to said multiplex bus and responsive to said informational signals for deciding a radio volume by a predetermined algorithm and for sending a volume message on said multiplex bus; and
an audio unit coupled to said multiplex bus, said audio unit including means responsive to said volume message for controlling sound output from said audio unit in accordance with said volume message.

Abstract
A multiplex bus that is corrected to an AM/FM/CD radio. The multiplex bus couples communicating microprocessors in modules, including a body computer, an engine controller, a transmission controller, and other functional components of an automobile. The radio includes components for audio amplified clipping detection and remote control of the volume. The computer controls the volume and clipping features via the multiplex bus. These features, and the programming of the computer with respect to the features are controllable by diagnostic tools external to the system, which may by hooked up to the bus in an assembly plant or an automobile service center. So programmed, the body computer is be able to read the vehicle speed, rpm, transmission gear, and acceleration and decide, in accordance with a predetermined algorithm or programmed instructions, whether to increase or decrease the radio volume. The decision depends on the vehicle characteristics and/or the preference of the prime listener.

8. A method of controlling radio volume to the preference of a prime listener in a vehicle having a plurality of modules for controlling and monitoring utilities of the vehicle, said modules being coupled by a multiplex bus to a programmable body computer and to a radio installed in the vehicle, the method comprising the steps of:
-
accessing said bus with a electronic diagnostic tool; controlling said modules with said diagnostic tool using said bus while increasing and decreasing the radio volume to the preference of said prime listener to correlate, in steps, signals associated with levels of the control of said modules with levels of the radio volume; and programming said body computer with instructions to increase and decrease the volume of the radio in accordance with correlated levels of the control of said modules. - View Dependent Claims (9)
