Cars with antiblocking system can be equipped by electronic system of stabilisation also. By means of stabilisation system the control over dynamics of the car in limiting modes is carried out, for example at overcoming of turns on high speed. Danger of a pulling down or car drift essentially reduces ся at all possible conditions of a road covering.
Usually the stabilisation system always is included. Only in certain unusual cases when proslipping of wheels is desirable to switch off preferably system.
Action of electronic system of stabilisation
In electronic system of stabilisation are integrated antiblocking system and both противобуксовочные systems. Except that information which is necessary for these systems for the block of management of electronic system of stabilisation the additional data which is required is delivered by high-sensitivity sensor controls. Sizes of accelerations are measured in a cross-section plane, pressure in system of a drive of brakes and an angle of rotation of operated wheels speed of moving of a body round a vertical axis of the car.
On the basis of the data about an angle of rotation of operated wheels and speed of the car that direction in which is defined the driver of the car intends to move and it is constantly compared with actual behaviour of the car. At inconsistency of these factors when the pulling down or car drift begins, the stabilisation system automatically brakes a certain wheel.
By means of those forces which arise at притормаживании the necessary wheel, the car comes back in a condition of dynamic stability. At superfluous поворачиваемости the car (aspiration) braking influence is put to drift of a back part of the car to forward, external in relation to turn to a wheel, at insufficient поворачиваемости (the aspiration to a pulling down of a forward part of the car кнаружи turn) is braked a back internal wheel. |
