Vertaling van "angular velocity detection" in Chinees
角速度检测
By using such configurations as described above, the vibration gyro element 20 achieves downsizing and improvement of the angular velocity detection sensitivity.
通过采用这些结构，从而使振动陀螺元件20实现了小型化及角速度检测灵敏度的提高。
The gyro sensor 74 constitutes an angular velocity detection part and generates angular velocity data.
陀螺传感器74构成角速度检测部分并产生角速度数据。
Furthermore, according to the gyro sensor, by generating the feedback signal using the constant voltage source, an angular velocity detection signal unaffected by variations in supply voltage can be obtained.
又，陀螺传感器中，通过以定电压源生成反馈信号，可获得不受电源电压变动的影响的角速度检测信号。
In the above gyro sensor 100, since the synchronous detection is performed by using the digital signal that is converted from the detection signal V9 by the delta-sigma modulator 70, errors can be prevented from occurring in the angular velocity detection signal V28 due to harmonics induced by such factors as periodic external mechanical vibrations, etc. Furthermore, since the detection is performed by using the switching of the first switch 63, there is also offered the advantage that the entire gyro sensor 100 can be implemented in CMOS.
上述陀螺传感器100中，进行同步检波时，通过Δ∑调制器70，采用将检波信号V9转为数字信号后的信号进行同步检波，因此能防止由于高次谐波，例如，来自外部的周期性的机械振动原因等造成的角速度检测信号V28中产生误差。
Specifically, the magnitude of the vibration leakage component has a correlation with the angular velocity detection sensitivity, and the presence or absence of failure of the gyro sensor element 100 can be determined by monitoring the magnitude of the vibration leakage component.
即，振动泄漏分量的大小与角速度的检测灵敏度之间存在相关性，通过对振动泄漏分量的大小进行监视，从而能够对陀螺传感器元件100有无故障进行判断。
f1. In rare cases, although a gyro sensor is designed with f2=f1, in this case, detection sensitivity may increase, but it is disadvantageous that it is difficult to secure a sufficient angular velocity detection band.
虽然在极少的情况下，有时会以f2＝f1的形式设计陀螺传感器，但是存在如下的缺点，即，虽然检测灵敏度增大，但无法保证所检测的角速度的频带。
Further, according to the above-described second embodiment, description has been given for a case where the cellular phone 101 serving as a cellular phone having a navigation function is made up with the GPS processing unit 21 or position calculation unit 25 serving as a measuring unit, the Y-axis gyro sensor 5 serving as a horizontal angular velocity detection unit, the correction value generating unit 40 serving as a correction value generating unit, the offset correction unit 42 serving as a correction unit, the inclination information generating unit 43 serving as the inclination information generating unit, the navigation unit 26 serving as a map position calculation unit, and a cellular phone unit 110 serving as a cellular phone.
另外，根据上述的第二实施例，描述了这样一种情况： 其中， 用作具有导航功能的蜂窝电话的蜂窝电话101由用作测量单元的GPS处理单元21或位置计算单元25、用作水平轴角速度检测单元的Y轴陀螺传感器5、用作校正值产生单元的校正值产生单元40、用作校正单元的偏移校正单元42、用作倾斜信息产生单元的倾斜信息产生单元43、用作地图位置计算单元的导航单元26和用作蜂窝电话的蜂窝电话单元110构成。
