摘要： A radar apparatus of the present invention is provided with at least one horn antenna for radiating and receiving linearly-polarized radio waves. The inner circumferential surface of the horn antenna has a top surface and a bottom surface, and a right side surface and a left side surface facing each other, the top surface and the bottom surface being perpendicular to a direction of the electrical field and facing each other. The top surface and the bottom surface define a first steeply-widened portion having a first rate of a widening rate, and define a first gently-widened portion having a second rate of a widening rate, the second rate being lower than the first rate. High-order modes can be generated within the horn antenna by the first steeply-widened portion and the first gently-widened portion to reduce sidelobes in the elevation angle direction.

摘要： In a vehicle-mounted image recognition apparatus, a resolution of an image projected on an imaging plane of an image sensor is different at a position away from a center between a circumferential direction and a radial direction. To make a circumferential resolution higher than a radial resolution, at least a lower half of the imaging plane is located closer to a circumferential focus than a middle of a radial focus and the circumferential focus at a position off the optical axis center of the image projected on the image sensor through the image-forming optical system. This is achieved by adjusting the position of the imaging plane when manufacturing or by selecting a lens with high circumferential resolution. This apparatus improves recognition accuracy in recognizing traffic lanes without using an expensive lens exhibiting high resolution both in the circumferential direction and in the radial direction.
摘要翻译：在车载图像识别装置中，投射在图像传感器的成像面上的图像的分辨率在远离圆周方向和径向方向的中心的位置不同。为了使圆周分辨率高于径向分辨率，成像平面的至少下半部分位于比径向聚焦的中间更靠近周围的焦点，并且在远离图像的光轴中心的位置处的周向聚焦在图像传感器上通过图像形成光学系统。这是通过在制造时选择成像平面的位置或通过选择具有高周向分辨率的透镜来实现的。该装置在不使用在圆周方向和径向方向上表现出高分辨率的昂贵透镜的情况下，提高了识别行车道的识别精度。

摘要： A radar apparatus of the present invention includes an antenna member capable of emitting or receiving microwaves; a feed unit including a plurality of waveguides each having one end connected to a base portion of the antenna member; a radio frequency circuit in contact with the feed unit; an information-processing circuit; a signal line connecting the radio frequency circuit and the information-processing circuit; and a common board equipped with the radio frequency circuit and the information-processing circuit. Since planar positions of the information-processing circuit and the radio frequency circuit on the common board do not overlap with each other, it is possible to downsize the radar apparatus. The common board includes a closed foil made of conductive material and surrounding the radio frequency circuit, and the closed foil made of conductive material is grounded.

摘要： A motor control device includes an inverter circuit to convert a DC power source voltage into a three-phase AC voltage and supply the three-phase AC voltage to the three-phase motor and a controller to generate three-phase PWM signals based on three-phase duty command values updated at a predetermined updating cycle and control the inverter circuit based on the three-phase PWM signals. The controller is configured or programmed to shift, when duty command values of at least two phases of the three-phase duty command values updated at a first update timing are the same, the duty command value of one phase of the duty command values of the two phases by a predetermined shift amount and shifts a duty command value of the one phase of the three-phase duty command values updated at a second update timing which is an update timing next to the first update timing by the shift amount in a direction opposite to a shift direction at the first update timing.
