6.1.10. Integrated sensor of management of dynamic stability

The sensor of angular speed of roving and the sensor of a side overload are integrated.

The integrated sensor is installed on the left side of the lever of the parking brake (model with the left arrangement of steering) or on the right side of the lever of the parking brake (model with the right arrangement of steering) and determines the angular speed of roving of the car (angular speed of the car in turn) and longitudinal acceleration. The sensor transmits a signal to the DSC HU/CM system.

The output tension of the integrated sensor 2.5 in when the car is not mobile) changes according to the angular speed of roving and size of longitudinal acceleration.

Angular speed of roving is defined when the sensor determines Coriolis's strength proportional to rotation speed.

The size of longitudinal acceleration is defined when the sensor determines the inertia force proportional to the longitudinal acceleration operating on a silicon sensitive element.

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