Abstract
A method of configuring an acoustics system of a convertible vehicle to receive speech from an occupant of the vehicle who is using hand-free technology. The position of the top of the convertible is first determined and based upon whether the top is up or down, an audio reception configuration is selected. The audio reception configuration includes a set of tuning parameters and a microphone arrangement. The acoustics system is then configured based upon the determination of whether the top is up or down.
Claims16
A method of configuring a hands-free acoustics system of a convertible vehicle, comprising the steps of:
- a) configuring a telematics unit in the convertible vehicle to determine a position of a top of a convertible vehicle, wherein the positions include a top-up position and a top-down position, wherein the hands-free acoustics system has at least two audio reception configurations for receiving speech from an occupant of the vehicle, wherein a first audio reception configuration is associated with the top-up position and a second audio reception configuration is associated with the top-down position;
- and then
- b) configuring the acoustics system to use the first audio reception configuration when the telematics unit determines the top of the convertible vehicle is in the top-up position and to use the second audio reception configuration when the telematics unit determines the top of the convertible vehicle is in the top-down position, wherein the configuration of step (b) includes speech recognition instructions and instructions associated with the first and second audio reception configurations, both of which are stored on vehicle memory and executable by a vehicle processor.
An acoustic system for a convertible vehicle, comprising:
- a) a vehicle user interface in the vehicle, wherein the vehicle user interface comprises a memory device and a processor, wherein the memory stores a first audio reception configuration and a second audio reception configuration, wherein each of the first and second audio reception configurations are predetermined and associated with a different position of a top of the convertible vehicle;
- b) at least one position sensor in the vehicle having a sensor input which is coupled to the top of the convertible vehicle and a sensor output which is coupled to the vehicle user interface, wherein the sensor input detects the position of the top of the convertible vehicle, wherein a first position is a top-up position and a second position is a top-down position;
- and
- c) a microphone system in the vehicle that includes at least one microphone and is coupled to the vehicle user interface,
- wherein the processor is configured using instructions stored on memory of the vehicle user interface to select one of the first or second audio reception configurations based on the sensor output.
A method of providing hands-free services using an acoustics system of a convertible vehicle, comprising the steps of:
- a) configuring a telematics unit in the convertible vehicle to determine a position of a top of the convertible vehicle,
- wherein the positions include a top-up position and a top-down position, wherein the acoustics system comprises at least two audio reception configurations that include a first audio reception configuration associated with the top-up position and a second audio reception configuration associated with the top-down position, wherein the first audio reception configuration includes a first set of tuning parameters for use with a uni-directional microphone in the convertible vehicle, wherein the second audio reception configuration includes a second set of tuning parameters for use with an omni-directional microphone in the convertible vehicle;
- and then
- b) providing hands-free services:
- using the uni-directional microphone, the first audio reception configuration, and the first set of tuning parameters when it is determined that the top of the vehicle is in the top-up position, or
- using the omni-directional microphone, the second audio reception configuration, and the second set of tuning parameters when it is determined that the top of the vehicle is in the top-down position.
