    • A headlight optical axis control unit of a vehicle capable of reducing cost, improving accuracy and ensuring safety is provided. An inclination angle detecting sensor placed in the front of a vehicle is connected to a control unit, and includes two transceivers of ultrasonic sensors. The two transceivers obtain the levels at their locations from the phase differences between the emitted waves and the reflected waves from a road surface, and measure the inclination angle from the level differences. The inclination angle is continuously detected during running of the vehicle. The measured values of the inclination angle are subjected to the cumulative sum and cumulative averaging. According to the average value, the control unit adjusts the angle of the optical axis of the headlights via headlight optical axis control sections.
    • 提供了能够降低成本,提高精度并确保安全性的车辆的前照灯光轴控制单元。 放置在车辆前部的倾斜角检测传感器连接到控制单元,并且包括两个超声波传感器的收发器。 两个收发器从发射波和路面反射波之间的相位差获取其位置处的电平,并从电平差测量倾斜角。 在车辆行驶期间连续检测到倾斜角度。 对倾斜角度的测量值进行累加和累积平均。 根据平均值,控制单元通过头灯光轴控制部调节前照灯的光轴的角度。

    • A wheel slip ratio correction apparatus is disclosed which includes a calculation unit for calculating a slip ratio of each wheel when the brakes are not applied to either a front wheel or a rear wheel of a mobile vehicle such as a motorcycle. The calculation unit calculates a difference between a front wheel slip ratio and a rear wheel slip ratio, and changes in the slip ratio difference, which occur within a predetermined time period, are monitored by detecting if the slip ratio difference is stable and is within a predetermined range for a predetermined period of time. If the slip ratio difference is stable and is within the predetermined range for the predetermined period of time, a correction value, dependent upon the slip ratio difference, is subtracted from the greater of the front wheel slip ratio and rear wheel slip ratio so that any undesirable difference between the front and rear wheel slip ratios may be eliminated.

    • An estimated vehicle speed detection apparatus for motorcycles calculates an estimated vehicle speed based on a front wheel speed and a rear wheel speed and applies antilock brake control to each of front and rear wheels based on a calculated estimated vehicle speed. The apparatus includes a memory for storing the estimated vehicle speed at the time an application of antilock brake control to either the front or rear wheel is started, or an application of brakes to either the front or rear wheel starts. The apparatus further includes a calculation unit for comparing the front wheel speed and the rear wheel speed to calculate the estimated vehicle speed based on the higher of the front wheel speed or the rear wheel speed, while antilock brake control is applied to the front or rear wheel or either a front brake or a rear brake is applied. In this case, the rear wheel speed does not exceed the estimated vehicle speed previously stored in the memory.
    • 用于摩托车的估计车速检测装置基于前轮速度和后轮速度计算估计车速,并且基于所计算的估计车速对前后轮中的每一个进行防抱死制动控制。 该装置包括用于在对前轮或后轮施加防抱死制动控制或者向前轮或后轮施加制动器时存储估计车速的存储器。 该装置还包括:计算单元,用于比较前轮速度和后轮速度,以基于前轮速度或后轮速度的较高者来计算估计车速,同时防抱死制动控制被施加到前侧或后侧 车轮或前制动器或后制动器。 在这种情况下,后轮速度不超过预先存储在存储器中的估计车速。
