Embodiment Construction

[0029] Referring specifically to the drawings, reference numeral 100 denotes a control system for the stability of the vehicle 1 .

[0030] As shown, a vehicle 1 has a vehicle body 2 and a plurality of wheels 3 which are the points of contact of the vehicle with the ground.

[0031] Preferably, the vehicle 1 has four wheels 3 .

[0032] The vehicle 1 also has a longitudinal extension axis x, a transverse extension axis y and a vertical extension axis z.

[0033] The vehicle 1 also comprises at least one semi-active shock absorber 4 for each wheel 3 equipped with the vehicle 1; since the semi-active shock absorber 4 is preferably technically identical for each wheel, for the sake of simplicity, hereinafter Only one shock absorber 4 is mentioned.

[0034] The shock absorber 4 is interposed between the respective wheel 3 and the vehicle body 2 and is configured to damp oscillations of the vehicle body 2 along the axis z of vertical extension of the vehicle 1 .

Abstract

A system (100) for controlling the stability of a vehicle (1) equipped with semi-active dampers (4) comprises: an actuator (5), a plurality of sensors (6C, 6D), a low-level control unit (8L), a high-level control unit (8H) and a mid-level control unit (8M) adapted to execute an algorithm (A) for calculating a damping level (C ref ).

Description

technical field [0001] The present invention relates to a system and method for controlling the stability of a vehicle, in particular a system and method for controlling the stability of a vehicle equipped with a semi-active suspension. Background technique [0002] The suspension system has a great influence on the drivability and safety of the vehicle, as well as the driver's comfort on uneven roads. [0003] Modern stability control systems primarily involve two types of suspensions: electro-pneumatic and semi-active. [0004] The difference between these two types of suspensions is that electropneumatic suspensions are active and are able to apply force, while semi-active suspensions are passive and the resistance of the suspension to retract and extend is adjustable. [0005] However, semi-active suspensions have the advantage of having a higher control frequency and being less bulky in terms of weight and space, and since they are passive they consume less energy. ...
