Problems solved by technology

However, in the case of sharp horizontal directivity, such as Image 6 As shown, near the vehicle 2, there is a dead angle 1b
Therefore, radar 1 cannot detect objects located near vehicle 2

Embodiment approach 1

[0036] Hereinafter, a method of mounting a radar for a vehicle and an embodiment of the radar for a vehicle according to the present invention will be described with reference to the drawings. figure 1 It is a side view showing a state in which the vehicle radar 11 according to Embodiment 1 is mounted on a vehicle. The transmitting antenna 14 of the vehicle radar 11 is installed in the bumper of the vehicle 12 [height H from the road surface 13 1 (e.g. 0.5m) position]. In addition, the vehicle radar 11 is installed so that the axis of the directional radiation pattern of the antenna faces upward at an angle θ1 with respect to the horizontal direction. In addition, 11 a in the figure shows a vertical directional radiation pattern of the transmitting antenna 14 of the vehicle radar 11 .

[0037] figure 2 It is a schematic diagram showing a state in which vehicle radar 11 is mounted on vehicle 12 such that the axis of the vertical directional radiation pattern of transmittin...

Embodiment approach 2

[0058] Next, the vehicle radar 11 according to Embodiment 2 will be described. In Embodiment 2, mounting members used when mounting the vehicle radar 11 on the vehicle 12 will be described in detail. In addition, the same components as in Embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted.

[0059] FIG. 11 is a side view showing a bracket 100 (mounting member) used when mounting the vehicle radar 11 according to Embodiment 1 to a vehicle 12 . FIG. 11( a ) is a side view of the bracket 100 when the bottom plate 105 of the bracket 100 is brought into contact with a flat surface. FIG. 11( b ) shows the bracket 100 viewed from the direction of arrow XIB in FIG. 11( a ). The bracket 100 has side panels 101 , side panels 102 and a bottom panel 105 . The side plate 101 and the side plate 102 stand substantially vertically from the bottom plate 105 . The side plate 101 and the side plate 102 each have two protruding pieces 103a, 103b prot...

Embodiment approach 3

[0068] Next, a vehicle radar according to Embodiment 3 will be described. image 3 It is a schematic diagram showing a state in which vehicle radar 21 is mounted on vehicle 22 such that the normal line of the radio wave emitting surface of vehicle radar 21 in Embodiment 3 is parallel to the horizontal direction of road surface 23 . The transmitting antenna (not shown) of vehicle radar 21 is installed in the bumper of vehicle 22 [from the height H of road surface 23 1 (e.g. 0.5m) position]. In addition, the vehicle radar 21 is configured such that the vertical directional radiation pattern of the antenna is asymmetrical with respect to the directional axis X. As shown in FIG. 21 a in the figure shows the directional radiation pattern in the vertical plane of the antenna of the vehicle radar 21 . An electrical inclination is provided in advance to the transmitting antenna of the vehicle radar 21 . Therefore, the angle between the directional axis X and the horizontal directio...

Abstract

An attachment method attaches a bracket to a vehicle, and attaches a radar to the bracket so that an axis of a directivity pattern of an antenna directs upward with respect to a horizontal direction. The antenna of the radar has an asymmetric vertical directivity pattern with respect to the axis of the directivity pattern.

Description

technical field [0001] The present invention relates to a vehicle radar (Radar: Radio detecting and ranging) installation method and the vehicle radar. More specifically, it relates to a mounting method and a vehicle radar for appropriately mounting a vehicle radar for monitoring the front, rear, etc. of a vehicle to the vehicle. Background technique [0002] In conventional systems that support the operation of vehicles, radar is used to measure the inter-vehicle distance and relative speed between the own vehicle and the preceding vehicle. In addition, the conventional support system controls the vehicle so as to maintain the inter-vehicle distance between the own vehicle and the preceding vehicle based on the above-mentioned measured value. [0003] Figure 5 It is a schematic diagram showing a state in which a conventional vehicle radar is used. 1 in the figure shows a vehicle radar. An antenna (not shown) of the vehicle radar 1 is attached to the vicinity of a radiat...
