Embodiment Construction

[0031] Hereinafter, the structure of the external sensor attachment part according to the embodiment of the present invention will be described in detail with reference to the drawings.

[0032] In addition, in the drawings shown below, in principle, the same reference numerals are assigned between components having the same function or between components having functions corresponding to each other. In addition, for convenience of description, the size and shape of components may be schematically shown in a deformed or exaggerated manner.

[0033] In addition, in the following description, the up-down direction, the vehicle width direction, and the front-rear direction are directions based on the state where the host vehicle 11 is placed horizontally.

[0034] [Schematic structure of the own vehicle 11 to which the structure of the external sensor mounting part according to the embodiment of the present invention is applied]

[0035] First, properly refer to figure 1 , Fi...

Abstract

The invention provides an external sensor attachment portion structure. In an external sensor attachment portion structure of the present invention, an external sensor (25) includes: a sensor main body (33) including a detection unit that detects external information; a sensor attachment bracket (35) used to attach the sensor main body to a vehicle body frame member; and a sensor garnish (37) 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 externalsensor 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 inthe 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.

Description

technical field [0001] The present invention relates to an external sensor attachment structure used when an external sensor (external sensor) is mounted on a vehicle body structure of an own vehicle, wherein the external sensor detects external information on objects existing around the own vehicle. Background technique [0002] Recently, a so-called self-driving vehicle that detects external information related to objects existing around the own vehicle through an external sensor such as a radar ranging sensor, and performs A so-called self-driving vehicle that controls the autonomous driving of the own vehicle including steering, acceleration and deceleration. [0003] For example, Patent Document 1 describes a technical solution of a vehicle-mounted radar device, which has a transceiver unit, a detection unit, and a cover member, wherein the transceiver unit transmits electromagnetic waves and receives reflected waves; The reflected wave of the electromagnetic wave of t...
