    • A method and an apparatus for estimating behaviors of a vehicle are provided. At least two GPS antennas are located along a longitudinal axis of a vehicle so that speed vectors at the positions where the GPS antennas are located can be determined based on GPS signals received by the GPS antennas. The speed vectors are known to be estimated with high accuracy based on the GPS signals. The positions of the GPS antennas on the local coordinate system are estimated based on such highly accurate speed vectors, so that the estimated positions may also have high accuracy. Based on a line connecting these highly accurate positions of the GPS antennas, an inclination of the longitudinal axis of the vehicle is estimated. Use of the high-accuracy speed vectors enables high-accuracy estimation on the positions of the GPS antennas and the vehicle direction on the local coordinate system.

    • Each of three light receiving sections has a P-type well having a P+-type layer and an N-type layer formed therein. The P+-type layer is diffused from substrate surface to depth d1. A PN junction forming portion of the N-type layer is diffused from depth d1 to depth d2 which is greater than depth d1 so as to form, with the P-type well, a PN junction of a photodiode at depth d2. Depths d1 as well as depths d2 of the three light receiving sections are different from each other. The N-type layer has a charge output portion which is diffused from the PN junction to the substrate surface, and which is coupled by circuit coupling to a MOS transistor for reading out charge. This allows each light receiving section to have spectral characteristics, thereby providing a solid state imaging element and a solid state imaging device without using color filters.
    • 三个光接收部分中的每一个具有P型阱,其中形成有P +型层和N型层。 P +型层从衬底表面扩散到深度d1。 N型层的PN结形成部分从深度d1扩散到深度d2,深度d1大于深度d1,以便与P型阱形成深度为d2的光电二极管的PN结。 三个光接收部的深度d1以及深度d2彼此不同。 N型层具有从PN结扩散到衬底表面的电荷输出部分,其通过电路耦合耦合到用于读出电荷的MOS晶体管。 这允许每个光接收部分具有光谱特性,从而提供固态成像元件和固态成像器件而不使用滤色器。

    • In an imaging device having an all-pixel read mode for reading signals from all pixels and a pixel downsampling read mode for reading signals by appropriately discarding pixels, adjacent ones of pixels use a floating diffusion capacitance, an amplifying transistor, a reset switch and a selection switch in common. In the pixel downsampling read mode, not only a primary capacitance but also a photodiode in each pixel to be discarded are used as capacitances for storing signal charges transferred from transfer switches. This makes it possible to lower the gate voltage of the amplifying transistor as compared with the case of using only the primary capacitance as a capacitance for storing signal charges transferred from a transfer switch to reduce the sensitivity of the pixels, thereby reducing the occurrence of flicker.
    • 在具有用于从所有像素读取信号的全像素读取模式和用于通过适当地丢弃像素来读取信号的像素下采样读取模式的成像装置中,相邻的像素使用浮动扩散电容,放大晶体管,复位开关和 选择开关共同。 在像素下采样读取模式中,不仅要将要丢弃的每个像素中的一次电容,而且还将光电二极管用作用于存储从转换开关传送的信号电荷的电容。 与仅使用一次电容作为用于存储从转换开关传送的信号电荷的电容的情况相比,可以降低放大晶体管的栅极电压,以降低像素的灵敏度,从而减少闪烁的发生 。

    • An image sensor includes a color filter array including a primary color pixel such as a green filter pixel for sensing a predetermined primary color, a first secondary color pixel such as a yellow filter pixel, and a second secondary color pixel such as a cyan filter pixel. The primary color pixel, the first secondary color pixel, and the second secondary color pixel form different area ratios in the color filter array. For example, the area ratio of the yellow filter pixel to the cyan filter pixel and the green filter pixel is 2:1:1 in the color filter array. In addition, the color filters of the pixels are compensated for crosstalk effect. Such an image sensor has enhanced color reproducibility and sensitivity.

    • In a state where a driver sees a region near a vehicle, a finally-requested output-shaft torque is set so that a response is hastened in a deceleration and slowed in an acceleration. Thereby, a vehicle takes a forward descending position in which the front end of the vehicle is descending, which gives a driver a sense of deceleration or a sense of turning. Further, this position causes a front wheel load acting on the ground to increase and a rear wheel load acting on the ground to decrease, in comparison to a normal position. This thereby makes it easier for the vehicle to decelerate when practically decelerating or turning, and further enables turning to slightly over-steer. A resultant vehicular kinetic characteristic becomes comparable with a sense that is expected by the driver.
    • 在驾驶员看到车辆附近的区域的状态下,设定最终请求的输出轴转矩,使得在减速中加速响应并且加速减速。 因此,车辆处于车辆前端下降的向前下降位置,这给了驾驶员减速感或转向感。 此外,与正常位置相比,该位置导致作用在地面上的前轮负载增加并且作用在地面上的后轮负载减小。 由此,在实际上减速或转动时车辆变得更容易减速,并且能够进一步转向稍微转向。 所得到的车辆动力特性与驾驶员预期的感觉相当。

    • Adjacent pixels in a pixel circuit of an imaging device use a primary capacitance, an amplifying transistor, a reset switch and a selection switch in common. Each pixel has a photodiode and a transfer switch having first and second gates provided on the photodiode side and the primary capacitance side, respectively. In a pixel downsampling read mode, the first and second gate voltages of each pixel to be discarded are brought to high level, and thereafter the first and second gate voltages of each pixel to be read are brought to high level, to transfer charge generated in the photodiode of the pixel to be read to the primary capacitance and the photodiode in each pixel to be discarded. This enables reduction of the potential of the primary capacitance, and hence reduction of the pixel sensitivity than using only the primary capacitance to store charge transferred from the transfer switch.
    • 成像装置的像素电路中的相邻像素共同使用一次电容,放大晶体管,复位开关和选择开关。 每个像素具有光电二极管和转移开关,分别具有设置在光电二极管侧和初级电容侧的第一和第二栅极。 在像素下采样读取模式中,要丢弃的每个像素的第一和第二栅极电压被提高到高电平,然后将要读取的每个像素的第一和第二栅极电压变为高电平, 要读取的像素的光电二极管和要丢弃的每个像素中的光电二极管。 这使得能够降低主电容的电位,并因此降低像素灵敏度,而不仅仅是使用一次电容来存储从转换开关传送的电荷。
