    • An automotive lane deviation prevention (LDP) apparatus includes a control unit connected to a yawing-motion control actuator for LDP control purposes. The control unit determines, based on information regarding a lane marking line detected based on a picture image in front of a host vehicle, whether the host vehicle is in a state FLD≠0 where there is an increased tendency for the host vehicle to deviate from the driving lane. The control unit executes, based on a state Fdw≠0 where the host vehicle is traveling on predetermined irregularities formed on or close to the lane marking line and the information regarding the lane marking line, vehicle yawing motion control by which the host vehicle returns to a central position of the driving lane, in a lane-marking non-detecting state Fcamready=0 where the lane marking line is out of an image pick-up enabling area.

    • Radio resources are utilized efficiently and the communication quality is improved by flexibly adapting to the state of radio waves at a base station varying every moment or the topology of the distribution area of contents in multicast communication. The base station (100) stores information including the flow distribution starting time, the error rate measuring period, the threshold in an intra-base station flow management table. When detecting that it becomes the time before the error rate measuring period from the flow distribution starting time, the reception quality of radio terminals in the communication area of the base station (100) is measured. A base station (100-b) where the reception quality exceeds the threshold redundantly transmits multicast data assigned to a plurality of radio resources (800-b1, 800-b3, 800-b5). A base station (100-a) where the reception quality does not exceed the threshold transmits multicast data assigned to a single radio resource (800-a1).
    • 无线资源被有效地利用,并且通过灵活地适应于每一时刻变化的基站的无线电波的状态或多播通信中的内容分布区域的拓扑来改善通信质量。 基站(100)在基站内流量管理表中存储包括流量分配开始时间,错误率测量周期,阈值的信息。 当检测到从流量分配开始时刻到达错误率测量期间之前的时间时,测量基站(100)的通信区域中的无线终端的接收质量。 接收质量超过阈值的基站(100-b)冗余地发送分配给多个无线电资源(800-b1,800-b3,800-b5)的多播数据。 接收质量不超过阈值的基站(100-a)发送分配给单个无线资源(800-a1)的多播数据。

    • An automotive lane deviation prevention apparatus sets and determines a yaw moment allotted amount corresponding to a yaw-moment-control lane-deviation-avoidance (LDA) controlled variable used to avoid a host vehicle's lane deviation by yaw moment control and a deceleration rate allotted amount corresponding to a deceleration-control LDA controlled variable used to avoid the host vehicle's lane deviation by deceleration control, based on a host vehicle's yaw angle, when the host vehicle has a tendency to deviate from a driving lane. A desired yaw moment is calculated based on the yaw moment allotted amount so that a yaw moment is produced in a direction in which the host vehicle's lane-deviation tendency is avoided. A controlled variable for deceleration control is calculated based on the deceleration rate allotted amount. A braking force of each individual road wheel is controlled based on the desired yaw moment and the controlled variable for deceleration control.
