Crossfire SRT-6 V6-3.2L SC VIN N (2005)
Yaw Rate Sensor: Description and Operation
YAW RATE/LATERAL ACCELERATION SENSOR
DESCRIPTION
The Mark 259 Braking System uses a combined Yaw Rate and Acceleration Sensor. The Yaw Rate/Lateral Acceleration Sensor is a combined sensor
and is located under the center console behind the gear shifter assembly.
The yaw rate portion of the sensor is used to detect any swerving motion of the vehicle.
The lateral acceleration portion of the sensor is used to inform the ESP control module of the amount of lateral acceleration forces during cornering.
OPERATION
The Yaw Rate/Lateral Acceleration Sensor is a combined sensor.
The yaw rate portion of the sensor is used to measure the yaw rate of the vehicle. When the vehicle turns, acceleration forces are produced which
cause torsion. This torsion change within the sensor is proportional of the yaw rate of the vehicle.
The lateral acceleration portion of the sensor measures the amount of lateral acceleration during cornering. This sensor uses a spring/mass type
element to measure the amount of lateral acceleration. The lateral acceleration that occurs during cornering causes the spring/mass element to move
from its normal position to a position corresponding to the magnitude of the lateral acceleration. Every change in the spring/mass element position
changes the output voltage of the sensor.
