In-vehicle acoustic monitoring system for driver and passenger

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations of operating a vehicle, the operations comprising:

• generating sound signals using one or more speakers disposed within the vehicle, wherein the sound signals are not audible;
• receiving reflected sound signals from a driver or a passenger of the vehicle by one or more microphones disposed within the vehicle;
• detecting a behavior-induced acoustic pattern based on the reflected sound signals received by the microphones;
• analyzing the behavior-induced acoustic pattern to determine a behavior of the driver or the passenger of the vehicle;
• and
• generating an alert according to the behavior of the driver or the passenger of the vehicle in view of a set of one or more rules.

A data processing system, comprising:

• a processor;
• and
• a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations of operating a vehicle, the operations including
• generating sound signals using one or more speakers disposed within the vehicle, wherein the sound signals are not audible,
• receiving reflected sound signals from a driver or a passenger of the vehicle by one or more microphones disposed within the vehicle,
• detecting a behavior-induced acoustic pattern based on the reflected sound signals received by the microphones,
• analyzing the behavior-induced acoustic pattern to determine a behavior of the driver or the passenger of the vehicle, and
• generating an alert according to the behavior of the driver or the passenger of the vehicle in view of a set of one or more rules.
