    • PROBLEM TO BE SOLVED: To enable control over the power consumption of the light of the luminous quantity controller to control the luminous quantity of the light, which is mounted on the vehicle, without degrading the visibility as much as possible.SOLUTION: The luminous quantity computing unit 10 acquires the position of an own vehicle (S120) and acquires the traffic congestion information including the information on a certain position and the information about the existence or non-existence of the traffic congestion in that position (S130). Addiitonally, when it specifies (S160) whether the own vehicle is congested based on the traffic congestion information and the position of the own vehicle while the own vehicle is congested, and the luminous quantity of the light is usually decreased (S180 as compared with the normal time). In such a luminous quantity computing unit 10, the own vehicle is congested and it is the time when it cannot run at a quick speed and when the driver of the own vehicle does not need to visual contact with a large area (distant place) so much, the luminous quantity of the light is decreased. Therefore, the power consumption by the light can be controlled without degrading the visibility as much as possible.
    • 要解决的问题:为了能够控制发光量控制器的光的功率消耗来控制安装在车辆上的光的发光量,而不会尽可能地降低可视性。

      解决方案:发光量计算单元10获取自身车辆的位置(S120),并且获取包括关于某个位置的信息的交通拥堵信息以及关于该交通拥堵的存在或不存在的信息 位置(S130)。 另外,当在本车辆拥堵时,当根据交通拥堵信息和本车辆的位置指定(S160)本车辆是否拥塞时,通常减少光的发光量(S180与 正常时间)。 在这样的发光量计算单元10中,本车辆拥挤,并且是不能以快速运行的时间,并且当本车辆的驾驶员不需要与大面积(遥远的地方)进行视觉接触时 很多,光的发光量减少了。 因此,可以控制光的功率消耗,而不会尽可能地降低可视性。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a technology in which a position of light sources is detected using an image picked up by an in-vehicle camera, and a direction of the illumination of an own vehicle headlight tracks the detected position, and the control of the reliability of the direction of illumination is enhanced by improving determination whether or not the direction of illumination tracks the detected light source.SOLUTION: An image of the vehicle surroundings is picked up, light sources are detected using this image that has thus been picked up, and from an image sensor that outputs the position information of the detected light sources, the position information of the light sources is acquired (step 110). Whether or not a light source is in the range of the advance of the vehicle which has been determined in accordance with the detection value of the steering angle or a yaw rate of the vehicle is then determined (step 120) using the position information of the light sources that has been thus acquired. If the result of this determination is positive, control is performed (step 140) to track the direction of the illumination of the headlights in the direction of the light source. If the result of the determination is negative, the headlights are controlled independently of the position of the light source (steps 150, 155).
