US 6,182,508 B2 · Structure of angular rate sensor

Abstract

An angular rate sensor is provided which measures the angular rate of a moving object such as an automotive vehicle. The angular rate sensor includes an installation base and an oscillator. The oscillator is excited to oscillate in a preselected direction perpendicular to an axis of rotation of the moving object and provides a signal indicative thereof. The installation base is used for installation of the sensor on the moving object and has an improved orientation structure for orienting the oscillator relative to the installation base during installation of the oscillator on the installation base so that the oscillator may oscillate in the preselected direction. The angular rate sensor is disposed within a casing through improved vibration isolators for absorbing unwanted vibrations impinging upon an operation of the sensor.

Dependent claims

An angular rate sensor apparatus for determining an angular rate of a moving object comprising:

a mounting member for mounting the angular rate sensor on the moving object;
a sensor unit including a base and an oscillator, the oscillator being mounted on said base and excited to oscillate so as to output a signal indicating an angular rate when subjected to rotation about a given axis;
and
a vibration isolator system isolating said sensor unit from vibration transmitted from said mounting member, said vibration isolator system connecting said mounting member and said sensor unit so that an elastic center associated with said vibration isolator system coincides with the center of gravity of said sensor unit, whereby vibration-induced elastic moments about the center of gravity of the sensor unit are essentially avoided.
