6.1.10. Incorporated sensor of management of dynamic stability

The sensor of angular speed of roving and the sensor of a lateral overload are incorporated.
The incorporated sensor is established on the left side of the lever of the parking brake (model with the left arrangement of a steering) or on the right side of the lever of the parking brake (model with the right arrangement of a steering) and defines angular speed of roving of the car (angular speed of the car in turn) and longitudinal acceleration. The sensor transmits a signal to DSC HU/CM system.
Target tension of the incorporated sensor 2.5 in when the car is motionless) changes according to angular speed of roving and size of longitudinal acceleration.
Angular speed of roving is defined, when the sensor defines Koriolis's proportional to speed of rotation the strength.
The size of longitudinal acceleration is defined, when the sensor defines the force of inertia proportional to longitudinal acceleration, operating on a silicon sensitive element.

NOTE
Sil Koriolis.
When the object located on a rotating disk, moves to its center, the force directed at right angle to the trajectory of moving of object is generated.
This leads to that the direction of moving of object remains invariable concerning a starting point, and the object does not reach the center.
This force rejecting object from the center, is called as Koriolis's strength, and the actual moving of object is rectilinear.
