B. YAW RATE SENSOR

(YRS)

WORKING PRINCIPLE

A yaw rate sensor is a gyroscopic device that

measures a vehicle’s angular velocity around its

vertical axis. The output is usually in degrees per

second or radians per second. The angle between

the vehicle's heading and vehicle actual

movement direction is called slip angle, which is

related to the yaw rate. The measurement is

based on the Coriolis Effect. The

Coriolis Effect

is an apparent deflection of moving objects when

they are viewed from a rotating reference frame.

This Sensor is used to measure the physical

effects of yawing, lateral and longitudinal

acceleration. In order to achieve this, the Sensor

features both a sensor element for yaw rate and

one or two sensor elements for acceleration.

The communication between Sensor and the ECU

is done by a CAN-Interface.
