    • A signal indicating an estimated body deceleration and a deceleration indicated by a detection signal from a G sensor are pass through first and second filters having different filter constants. Based on a resulting difference in response speeds thereof, it is determined whether sudden braking, i.e., quick depression, is being performed. If quick depression is determined, then even if an upper limit of a W/C pressure to rear wheels is set in order to prevent rear wheel locking precedent to front wheel locking, the W/C pressure is increased so as to exceed such an upper limit. Thus, a greater deceleration can be achieved than when the W/C pressure at the set upper limit is generated.
    • 表示来自G传感器的检测信号所表示的估计身体减速度和减速度的信号通过具有不同滤波器常数的第一和第二滤波器。 基于其响应速度的差异,确定是否正在执行突然制动,即快速按压。 如果确定快速按压,则即使设定了后轮W / C压力的上限,以防止后轮锁定的前轮锁定,则W / C压力增加以超过这种上限 限制。 因此,与产生设定上限的W / C压力相比,可以实现更大的减速度。

    • A magnetic rotation detector includes a magnetic rotor having magnetic bodies, a detecting body that detects a change in magnetic flux that is caused by the magnetic bodies as the magnetic rotor rotates; and an abnormality determination portion that monitors an apparent fluctuation in rotational speed of the magnetic rotor based on a result detected by the detecting body and that determines that the magnetic rotor is in an abnormal state if the fluctuation occurs at a specific position of the magnetic rotor. The abnormality determination portion detects the occurrence of the fluctuation at the specific position of the magnetic rotor by making a determination on a distance between apparent positions of the magnetic bodies which correspond to the apparent fluctuation in rotational speed and calculates the distance on the basis of a product of an interval of generation of noise in an output signal detected by the detecting body and a rotational speed of the magnetic rotor at the time of generation of noise.
    • 磁旋转检测器包括具有磁体的磁转子,检测体,其随着磁转子旋转而检测由磁体引起的磁通量的变化; 以及异常判定部,其基于由所述检测体检测出的结果来监视所述磁转子的转速的明显波动,并且如果在所述磁转子的特定位置发生变动,则所述异常判定部判定为所述磁转子处于异常状态 。 异常判定部通过对与旋转速度的明显波动对应的磁体的表观位置之间的距离进行判定来检测磁转子的特定位置处的波动的发生,并基于 由检测体检测到的输出信号中产生噪声的间隔的乘积和产生噪声时的磁转子的旋转速度的乘积。
