A yaw-rate sensor is a gyroscopic device that measures a vehicle's yaw rate, its angular velocity around its vertical axis. The angle between the vehicle's heading and velocity is called its slip angle , which is related to the yaw rate.
The output signal is proportional to the angular rate due to internal integration that occurs inside of the sensing element. The cutoff frequency for measurements can be as low as 0.005 Hz. A DC-sensitive angular rate sensor or gyroscope has a more complex design and uses measurement of Coriolis acceleration to determine angular rate..
A rate gyro is a type of gyroscope, which rather than indicating direction, indicates the rate of change of angle with time.If a gyro has only one gimbal ring, with consequently only one plane of freedom, it can be adapted for use as a rate gyro to measure a rate of angular movement.
A rate sensor is a sensor that measures a rate (or rate of change). It may refer to: Angular rate sensor. Rate gyro; Yaw-rate sensor; Heart rate sensor; Breath rate sensor; Oxygen transmission rate sensors; Moisture vapor transmission rate sensors
A longitudinal acceleration sensor that is similar to the lateral acceleration sensor in design, but provides additional information about road pitch, as well as being another sensor for vehicle acceleration and speed. A roll rate sensor that is similar to the yaw rate sensor in design, but improves the fidelity of the controller's vehicle ...
With sensor fusion, drift from the gyroscopes integration is compensated for by reference vectors, namely gravity, and the Earth's magnetic field. [3] This results in a drift-free orientation, making an AHRS a more cost effective solution than conventional high-grade IMUs that only integrate gyroscopes and rely on a high bias stability of the ...
For measuring speed or direction, a device uses multiple detectors and calculates the speed from the relative distances to particulates in the air or water. To measure tank or channel liquid level , and also sea level ( tide gauge ), the sensor measures the distance ( ranging ) to the surface of the fluid.
This correction enables a larger maximum permissible air gap at the speed sensor. On a module m = 1 target wheel these new sensors can tolerate an air gap of 1.4 mm, which is wider than that for conventional speed sensors on module m = 2 target wheels. On a module m = 2 target wheel the new speed sensors can tolerate gap of as much as 2.2 mm.
