    • An adaptive vehicle speed control system includes a vehicle speed sensor detecting a vehicle speed of a host vehicle which is subjected to adaptive vehicle speed control including preceding vehicle following control and vehicle speed control, and an inter-vehicle distance sensor detecting an inter-vehicle distance between the host vehicle and a preceding vehicle. A man-machine interface is provided for setting a set vehicle speed. Also provided is an adaptive vehicle speed controller which includes a desired inter-vehicle distance arithmetic-processing section calculating a desired inter-vehicle distance based on at least the host vehicle speed, a following control section determining a desired speed of the host vehicle based on the host vehicle speed and the inter-vehicle distance so that the inter-vehicle distance is brought closer to the desired inter-vehicle distance in presence of detection of the preceding vehicle, and a vehicle-speed adjustment device which adjusts the host vehicle speed to the desired speed. The adaptive vehicle speed controller includes a vehicle speed setting section which sets the desired speed to a speed value higher than a low-speed threshold value when the adaptive vehicle speed control function is engaged under a specified condition where the host vehicle speed is below the low-speed threshold value.

    • A light source 165 of a projection unit 16 AM modulates an electric current supplied to a built-in LED. The projection unit 16 projects the modulated light on a projection screen. A photoreceiver 171 receives, with a time lag, a reflected portion of the modulated light from the screen, which corresponds to a time required for the light to travel from its projection to its reception. A calculation unit 173 acquires a phase difference between the projected light and its reflection at a respective one of a plurality of points on the screen, acquires a distance from the projector to the respective one of the plurality of points on the screen, and then acquires an inclination angle of the screen. Because the distance from the projector to a respective one of the plurality of points on the screen is acquired based on the corresponding phase difference, the measurement accuracy is improved compared to the triangular distance measuring method. The projector requires no distance measurement-only light source, thereby reducing the size of the projector.
    • 投影单元16AM的光源165调制供给内置LED的电流。 投影单元16将调制光投射在投影屏幕上。 光接收器171在时间上接收来自屏幕的调制光的反射部分,其对应于光从其投影到其接收所需的时间。 计算单元173获取投影光与其在屏幕上的多个点中的各个点上的反射之间的相位差,获取从投影仪到屏幕上的多个点中的相应一个点的距离,然后获取 屏幕的倾斜角度。 由于基于对应的相位差获取投影仪到屏幕上的多个点中的相应一个点的距离,所以与三角距离测量方法相比,提高了测量精度。 投影机不需要距离测量光源,从而减小投影机的尺寸。
