    • In an accelerator slip control device for a motor vehicle of the present invention, when the opening .theta. mw of a main throttle valve 8 has exceeded a standby starting opening .theta. sb at which the occurrence of acceleration slip is predicted, the opening .theta. sn of a sub-throttle valve 12 is set to a standby opening .theta. ss. These standby starting opening .theta. sb and standby opening .theta. ss are learned and updated on the basis of the driving torque of an internal combustion engine 2 when the acceleration slip is being controlled at an optimum value by acceleration slip control executed in the past, thereby enabling preventing the occurrence of excessive acceleration slip. Furthermore, when the occurrence of the acceleration slip is predicted, even before the occurrence of the acceleration slip, it is possible to reduce the time required to drive the sub-throttle valve 12 to a target opening of the acceleration slip control, at the time of occurrence of the acceleration slip, because the opening of the sub-throttle valve 12 is preset to the standby opening .theta. ss which is suitable for restraining the acceleration slip.

    • A travel support apparatus sets a travel locus of a vehicle based on a gaze point of a driver of the vehicle. By utilizing the gaze point, the travel locus is calculated and set for the travel control of the vehicle, especially for a curved portion of a road, in a matching manner that the calculated travel locus approximates the travel locus created by the steering operation of the driver. The above locus calculation scheme generates a natural travel locus because the driver of the vehicle usually gazes at an exit of the curved portion of the road when he/she steers the vehicle on the road. The natural travel locus calculated and set by the travel support apparatus prevents the driver from having discomfort and/or unsafe feeling while the travel of the vehicle is controlled by the apparatus.
    • 旅行支援装置基于车辆的驾驶员的凝视点来设定车辆的行驶轨迹。 通过利用目视点,对于车辆的行驶控制,特别是对于道路的弯曲部分,以与计算出的行驶轨迹近似于由转向操作所产生的行驶轨迹的匹配方式来计算和设定行驶轨迹 司机。 上述轨迹计算方案产生自然旅行轨迹,因为当他/她在道路上驾驶车辆时,车辆的司机通常在道路的弯曲部分的出口处凝视。 由旅行支持装置计算和设置的自然行驶轨迹防止驾驶员在车辆的行驶由该装置控制的同时具有不适和/或不安全的感觉。

    • A stereophonic sound production system is provided which outputs audio signals in the form of sound through, for example, speakers to create virtual sound sources at desired locations in a three-dimensional space around a listener to develop a three-dimensional sound field. The virtual sound sources includes a direct sound source which produce a direct sound heard directly by the listener and Nth order reflected sound sources which produce Nth order reflected sounds resulting from reflection of the direct sound. The stereophonic sound production system produces audio signals to localize the Nth order reflected sound sources of the same order to the desired locations, as specified around a source-to-listener line extending from the direct sound source to the listener, thereby giving the listener a three-dimensional spatial perspective.
    • 提供了一种立体声产生系统,其通过例如扬声器以声音的形式输出音频信号,以在收听者周围的三维空间中的期望位置处产生虚拟声源,以形成三维声场。 虚拟声源包括直接声源,其产生听众直接听到的直接声音和产生由直接声音的反射产生的第N级反射声的第N级反射声源。 立体声声音产生系统产生音频信号,以将相同次序的第N阶反射声源定位到期望的位置,如围绕从直接声源延伸到听者的源到收听者线指定的,从而给收听者一个 三维空间视角。

    • 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.
