A vehicle has a prime mover to propel the vehicle, and a fluid circuit that defines a fluid passage and contains a coolant. The fluid circuit in thermal communication with the prime mover. A camera is positioned to image coolant within the fluid passage. A controller is configured to receive image data from the camera, process the image data to determine a state of the coolant in the fluid circuit, and output an indication to a user regarding the state of the coolant. A method of monitoring a fluid circuit in a vehicle is also provided.

A communication system for vehicles allowing occupants of an interior cab of the vehicle to orally communicate with persons outside the vehicle while all windows and doors of the vehicle are closed. The system employs an internal communications component in operative communication with an exterior communications component to communicate voice communications to and from both the person outside the vehicle and the occupants of the sealed interior cab of the vehicle.

Systems and methods for a transducer assembly for a vehicle having a resonating surface. The transducer assembly comprising a housing, a spacer connected to the housing, and a piezoelectric assembly disposed between the spacer and the housing. The spacer is configured to connect to the resonating surface to form an air gap between the resonating surface and the piezoelectric assembly.

An abnormal noise determination apparatus including a microphone array disposed inside a vehicle and an electronic control unit including a microprocessor. The microprocessor is configured to perform acquiring an abnormal noise data on an abnormal noise generated by a sound source disposed in a predetermined position inside the vehicle, the abnormal noise data including an information on a strength and a generation direction of the abnormal noise collected by the microphone array in advance or assumed to be collected by the microphone array; acquiring a traveling noise data including an information on a strength and a generation direction of a traveling noise collected by the microphone array during traveling of the vehicle; and determining whether the abnormal noise is included in the traveling noise of the vehicle, based on the abnormal noise data acquired and the traveling noise data acquired.

According to one aspect, a method for detecting a location from which at least one sound signal originates, includes obtaining, on a microphone array of a vehicle, the at least one sound signal from a sound source, the sound source being external to the vehicle, the vehicle having a plurality of sides. The method also includes identifying, based on at least one measure associated with the at least one sound signal as obtained on the microphone array, at least a first side of the plurality of sides as being closest to the sound source.

A microphone assembly for a vehicle headliner includes a housing arranged to be received within a substrate layer of the headliner and having an upper portion and a lower portion. A circuit board is mounted in the upper portion and has a microphone element coupled thereto. An insert bracket includes a base and a shaft member extending upwardly therefrom, the base having a plurality of apertures aligned with the shaft member, wherein the shaft member engages the lower portion to connect the insert bracket to the housing. A sealing gasket having at least one channel defining an air path extending therethrough is arranged to be received within the shaft member and extend between the base and the upper portion, providing acoustic sealing between the insert bracket and the housing such that the air path directs sound from a cabin of the vehicle through the apertures to the microphone element.

A transportation system is disclosed. The transportation system includes a vehicle, a plurality of seating assemblies positioned within a passenger compartment of the vehicle and defining an arrangement, a plurality of actuators that effect movement of various components of the plurality of seating assemblies, a plurality of sensors, and a controller. Specific examples of pre-set or pre-programmed arrangements are disclosed, as well as the ability to customize the arrangement. Additionally, exemplary methods are disclosed that illustrate transitions between a variety of the pre-set or pre-programmed arrangements.

Methods and systems for a vehicle headliner is provided. In one example, the headliner is a layered assembly, including a base substrate layer and a skin and is configured with a bracket inserted into the base substrate layer. The bracket has a top plate co-planar with a first surface of the base substrate layer and a continuous wall coupled to the top plate. The bracket is positioned in the base substrate layer such that the base substrate layer does not protrude into the skin.

Included are a first obtainer which obtains a first signal output from a first microphone, a second obtainer which obtains a second signal output from a second microphone installed in a position different from a position where first microphone is installed, a delayer which delays the second signal, a mixed sounds estimator which estimates noises mixed in the first signal on the basis of the second signal delayed by the delayer, and an eraser which erases the noises from the first signal, the noises being estimated by the mixed sounds estimator.
