Problems solved by technology

Also, since the output of high-frequency oscillators that can be used in vehicles is limited by law, it is not possible to increase the output of oscillators
As a result, the distance that can be monitored by radar is shortened

Embodiment Construction

[0037] figure 1 It is a simplified side view showing a vehicle 1 according to an exemplary embodiment of the present invention. The vehicle 1 is a passenger vehicle and includes a vehicle-mounted radar device 11 (hereinafter referred to as "radar device").

[0038] The radar device 11 is used for collision avoidance, driving assistance, automatic driving, and the like. The radar device 11 is mounted on the inner surface of the front windshield 12 of the vehicle 1 and is located in the vehicle cabin 13 . The vehicle compartment 13 does not need to be a space completely isolated from the outside, and the ceiling may be opened, for example. The radar device 11 is located in front of a rearview mirror 14 attached to a front windshield 12 . The vehicle 1 includes a drive mechanism 15 that moves the vehicle body 10 . The drive mechanism 15 is composed of an engine, a steering mechanism, a power transmission mechanism, wheels, and the like.

[0039] The front windshield 12 is fi...

Abstract

An on-vehicle radar device includes a mount and an antenna configured to transmit a transmission wave from an inner side of laminated glass, which includes an innermost glass layer, an outermost glass layer, and an intermediate resin layer, and receive a reflected wave. The antenna includes a transmitting antenna. When the mount is mounted on a bracket, the incident angle of the transmission wave on the innermost glass layer is greater than a Brewster angle on the inner surface of the innermost glass layer, and the incident angle of the transmission wave on the outermost glass layer is less than or equal to a Brewster angle between the outermost glass layer and the intermediate resin layer.

Description

technical field [0001] The present invention relates to a vehicle-mounted radar device and a vehicle. Background technique [0002] In recent years, research into collision avoidance, assisted driving, and autonomous driving has been conducted using a technology that uses radar to detect objects around the vehicle. For a long time, radar has been installed in the front of the car. The high-frequency oscillator needs to be placed near the antenna. In order to avoid wind and rain, it is necessary to take waterproof and weather-resistant measures such as protection with a radome. On the other hand, more sophisticated detection technologies have been developed using both detection by radar and camera images. [0003] In the specification of US Pat. No. 8,604,968, a radar camera sensor is proposed in which a radar and a camera are accommodated in a housing. The radar camera sensor is installed on the front windshield at a position in front of the car's rearview mirror. Radar ...
