Inaudible sound signals are generated by one or more speakers disposed in a vehicle. Inaudible sound signals reflected from a driver or occupant of the vehicle are received by one or more microphones disposed in the vehicle. A behavior-induced acoustic pattern is detected based on the reflected ultrasonic signal. The behavior-inducing acoustic pattern is analyzed to identify a behavior of a driver or occupant of the vehicle. A response or alert is generated based on the identified driver or passenger behavior in the vehicle.
听不见的声音信号由设置在车辆中的一个或多个扬声器生成。从车辆的驾驶员或乘客反射的听不见的声音信号由设置在车辆中的一个或多个麦克风接收。基于反射的超声信号检测行为诱发声学模式。分析行为诱发声学模式以识别车辆的驾驶员或乘客的行为。根据所识别的、车辆中的驾驶员或乘客行为来生成响应或警报。
