Abstract: A disclosure is presented for estimating height of an object using ultrasonic sensors carried onboard a vehicle. The height may be estimated by generating ultrasonic distance measurements based on a time of flight associated with ultrasonic reflections detected with the ultrasonic sensors, generating a three-dimensional (3D) occupancy grid to volumetrically represent at least a portion of an environment within field of view of the ultrasonic sensors, the 3D occupancy grid including a plurality of volumetric pixels (voxels), assigning a count value to each of the voxels based on the distance measurements, and estimating the height according to a relative spatial relationship between the vehicle and the voxel having the count value with a greatest value.

Abstract: Vehicles and methods for augmenting rearview displays for vehicles are provided. An exemplary method is provided for augmenting a rearview display for a vehicle having a gate moveable between a closed configuration and an opened configuration. The method includes collecting dynamic pixel images of an area behind the vehicle using a camera connected to the vehicle. Further, the method includes, in response to a command, displaying graphical overlays to the collected dynamic pixel images on a display screen, via a processor, wherein the graphical overlays depict an outline of the gate and/or projected path of the gate in the opened configuration.

Abstract: An ultrasonic transducer includes a transducer case and an ultrasonic element. The transducer case is formed into a bottomed, cylindrical shape having a side plate portion and a bottom plate portion that seals one end side of the side plate portion in an axial direction to configure a diaphragm. The ultrasonic element is fixedly supported to the bottom plate portion to face an interior space surrounded by the side plate portion and the bottom plate portion. The ultrasonic element is arranged in a position being offset in an in-plane direction orthogonal to the axial direction relative to a center position of the diaphragm in the in-plane direction to be capable of generating a first transmission wave having first directivity characteristics and a second transmission wave having second directivity characteristics that are directivity characteristics differing from the first directivity characteristics and in which sound pressure in the axial direction is decreased.

Abstract: A retainer member is equipped with a microphone facing portion, a drain path, and a stamped wall portion. The microphone facing portion is formed in a cylindrical shape matching an ultrasonic microphone is disposed outside the ultrasonic microphone in a radial direction extending radially from a longitudinal center line. The microphone facing portion extends from a body retaining portion toward a base side in an axial direction. The drain path extends through the microphone facing portion in the radial direction and is capable of discharging water from an inner space in the microphone facing portion. The stamped wall portion is formed in the microphone facing portion and faces the drain path through the longitudinal center line.

Abstract: An ultrasonic sensor includes an ultrasonic element and an element accommodation case. A side wall portion of the element accommodation case has a tubular shape surrounding a directional central axis. A bottom wall portion and a top wall portion of the element accommodation case cover ends of the side wall portion in a direction along the directional central axis. The top wall portion has a diaphragm portion. The bottom wall portion supports the ultrasonic element. For example, the ultrasonic element is opposed to the diaphragm portion across a gap defining an interval corresponding to an integral multiple of half of a wavelength of ultrasonic vibration. Alternatively, the diaphragm portion is formed of a material having an acoustic impedance of 50×105 Pa·s/m or more and 5000×105 Pa·s/m or less, and has a thickness of 1 mm or less.

Abstract: A filtering device includes a filtering circuit that connects a voltage source to a sensor and a switching circuit connected in parallel with the filtering circuit that allows current from the voltage source to bypass the filtering circuit and flow through the switching circuit. The switching circuit receives a mode signal from the sensor that indicates whether the sensor is in a high current or a low current mode, the switching circuit closes when the sensor is in the high current mode, and the switching circuit is opens when the sensor is in the low current mode.

Abstract: A sensor mounting state determination device includes distance measurement section that measures a distance to a road surface based on time from transmission of a transmission wave to reception of a reflection wave by an ultrasonic sensor that is mounted to a vehicle to transmit a transmission wave toward a road surface and receive a reflection wave reflected off the road surface. There is further provided a determination section configured to determine not only that the ultrasonic sensor is correctly mounted when the distance measured by the distance measurement section is identical to a predetermined distance, but also that the ultrasonic sensor is incorrectly mounted when the distance measured by the distance measurement section is not identical to the predetermined distance.
