A sensor arrangement for a vehicle includes a holding device holding a sensor and a connection arrangement connecting a holding device to a vehicle component. The connection arrangement moves the holding device between an operating position and at least one protecting position. The connection arrangement includes at least one lever arrangement that moves the holding device from the operating position to the at least one protecting position in response to an application of a collision force against the vehicle such that the holding device moves in at least one spatial direction including a first spatial direction, which corresponds to a first force component of the collision force. The connection arrangement includes at least one restoring arrangement that generates a restoring force applied against the at least one lever arrangement to move the holding device from the protecting position back to the operating position.

Provided is an object recognition device including a temporary setting unit and an update processing unit. The temporary setting unit sets, based on specifications of an external information sensor that has detected an object, a position of at least one candidate point on the object. The update processing unit corrects a position of a detection point with respect to the external information sensor at a time when the external information sensor has detected the object based on the position of the candidate point on the object, and updates track data indicating a track of the object based on a position of the detection point with respect to the external information sensor after the correction.

An active radio-frequency (RF) sensing technology for determining the relative and/or absolute state (e.g., position, velocity, and/or acceleration) of a target object (e.g., a person, a car, a truck a lamp post, a utility pole, a building) is described. The sensors described herein operate in the Terahertz band (300 GHz to 3 THz). An active RF sensing device comprises a substrate and first and second semiconductor dies mounted on the substrate. The first semiconductor die has an RF transmit antenna array integrated thereon, and the transmit antenna array comprises a first plurality of RF antennas configured to generate an RF signals having frequency content in the 300 GHz-3 THz band. The second semiconductor die has an RF receive antenna array integrated thereon, and the receive antenna array comprises a second plurality of RF antennas configured to receive RF signals having frequency content in the 300 GHz-3 THz band.

A radar sensing system for a vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals. The received radio signals are transmitted radio signals that are reflected from an object. A processor is operable to process an output of the receivers. The radar sensor includes a printed circuit board having circuitry disposed thereat. The radar sensor includes a radome. At least some of the antennas are embedded or encapsulated in the radome.

In an external sensor attachment portion structure of the present invention, an external sensor includes: a sensor main body including a detection unit that detects external information; a sensor attachment bracket used to attach the sensor main body to a vehicle body frame member; and a sensor garnish including a window portion through which the detection unit is exposed in front view. The sensor garnish is provided on an outer side of the host vehicle so as to expose the detection unit of the external sensor and cover the sensor main body and the sensor attachment bracket excluding the detection unit. Small gaps are provided between the sensor main body and a window frame of the window portion in the sensor garnish. The window frame includes a noise suppression portion that suppresses wind noise due to airflow passing through the gaps along a rearward direction of the host vehicle.

An autonomous vehicle (AV) includes a radar sensor system and a computing system that computes velocities of an object in a driving environment of the AV based upon radar data that is representative of radar returns received by the radar sensor system. The AV can be configured to compute a first velocity of the object based upon first radar data that is representative of the radar return from a first time to a second time. The AV can further be configured to compute a second velocity of the object based upon second radar data that includes at least a portion of the first radar data and further includes additional radar data representative of a radar return received subsequent to the second time. The AV can further be configured to control one of a propulsion system, a steering system, or a braking system to effectuate motion of the AV based upon the computed velocities.
