The system includes a processor configured to measure first, second, and third phase differences between the sound waves received from the source by the first and second microphones, the second and third microphones, and the third and first microphones; receive the first, second, and third phase difference maps from the memory; and identify a location of the source of the sound waves based on the first, second, and third phase differences and the first, second, and third phase difference maps for the first and second microphones, the second and third microphones, and the third and first microphones.

A vehicle intercom system is provided. The system includes one or more housings. Each housing includes a speaker, a microphone, and a lighting element. At least one housing is secured to the exterior of a vehicle via a fastener. In one embodiment, the exterior housing is adjacent to the vehicle mirrors. At least one housing is securable within the vehicle's cabin via a fastener. The speakers are operably connected to the microphone. The one or more housings are in wireless communication with one another and all housings are in wireless communication with an actuator. The actuator is securable to an internal surface of the vehicle cabin. The actuator is configured to activate the speaker and the microphone on each housing to enable two-way audible communication, allowing the driver or passengers to easily communicate with individuals located outside of the vehicle.

A microphone assembly includes a shaft element that is configured to be received in an opening defined by a base substrate layer of a headliner. The shaft element defines an air path. The microphone assembly includes a microphone element mounted on a circuit board within a housing. The microphone element is aligned with the air path such that the air path directs sound from the cabin to the microphone element. A vehicle cabin side of the headliner is covered by an acoustically transparent layer such that the microphone assembly is not visible within the vehicle cabin.

A system and method for accurately estimating engine noise at a virtual microphone location, such as an occupant's ear position, in an acoustic space in order to enhance performance of an Engine Order Cancellation (EOC) system is provided. A set of weights and transfer functions that are dependent on various vehicle parameters, such as frequency, load, and speed, may be employed to estimate noise at a position where there are no physical microphones present. The accurate estimation of engine noise at virtual location, such as an occupant's ear position, may be achieved using a frequency dependent weighted sum of filtered and unfiltered error signals measured at microphones mounted at various locations inside an acoustic space, such as a vehicle cabin, which may not be located near virtual location.

The present invention provides a vehicle mountable universal driver assistance device. This device includes a housing unit encasing a common module on which are mounted a first camera module, a second camera module, different from the first camera module, and a ranging module. The common module may be moved along an axis to adjust the viewing angle of the first camera, second camera and ranging module. The device can be mounted on windshield of any vehicle and can be calibrated accordingly. The intensity and frequency of the warning alert from the warning display device are based on the ambient noise level of the driver.

A vehicle having one or more cameras, configured to record one or more images of a driver of the vehicle. The camera(s) can be configured to send biometric image data derived from the image(s). The vehicle can include a computing system configured to receive the biometric data and to determine a risk score of the driver based on the received biometric data and an AI technique, such as an ANN or a decision tree. The received biometric data or a derivative thereof can be input for the AI technique. The computing system can also be configured to transmit the risk score of the driver to the customer so that the customer can decide whether to book the vehicle for a ride.

An agent device includes a microphone configured to collect a speech sound inside a vehicle cabin, a speaker configured to output a speech sound inside the vehicle cabin, and a plurality of agent function elements having different functions. Each of the plurality of agent function elements generates a speech sound of an agent that speaks to an occupant of a vehicle on the basis of a meaning of the speech sound collected by the microphone, causes the speaker to output the generated speech sound of the agent. The agent function element serving as a main agent that has a dialogue with the occupant is switched on the basis of content of the speech sound collected by the microphone.

A vehicle occupant detection system includes a housing. A microprocessor is mounted in the housing and is programmed to detect an engine engagement status of a vehicle. A camera is mounted on the housing and is directed forward of the housing. The camera electrically coupled to the microprocessor is programmed with facial recognition software to compare facial images against images captured by the camera. A motion sensor mounted on the housing detects motion forward of the housing. The camera captures an image when the motion sensor detects motion. A first condition is defined when the motion sensor detects motion, the camera captures an image prompting a facial recognition match and the microprocessor detects the vehicle is parked. A sound emitter is mounted on the housing and is electrically coupled to the microprocessor and emit a low decibel sound when the first condition is first attained.

A microphone apparatus for attachment to an exterior portion of a vehicle, the apparatus may include a housing maintaining a printed circuit board (PCB) and a microphone element positioned on the PCB, a sealing element arranged on one side of the housing and defining at least one housing opening, and a cover extending over the sealing element and defining a cover opening configured to align in an open state with the housing opening to enable ambient sound external to the vehicle to be transmitted to the microphone element, the cover configured to block the housing opening in a closed state to protect the microphone element.

Adaptive operations of a first noise control system and a second noise control system may include a speaker that outputs noise cancellation sound, a microphone that detects an error signal, an auxiliary filter that generates, from a noise signal, a correction signal that corrects the error signal so that a difference in a position between the microphone and a noise cancellation position is compensated, and an adaptive filter that performs an adaptive operation using the corrected error signal to generate the noise cancellation sound from the noise signal are alternately performed. A transfer function learned in a state in which the second noise control system is stopped is set in the auxiliary filter of the first noise control system, and a transfer function learned in a state in which the adaptive operation of the first noise control system is stopped is set in the auxiliary filter of the second noise control system.
