Electronic control separate type active anti-roll bar and anti-side-roll method

Abstract

The invention discloses an electronic control separate type active anti-roll bar and an anti-side-roll method. The active anti-roll bar comprises a left torsion bar, a right torsion bar, an active control module, a relative displacement sensor and a steering wheel angle sensor. The active control module comprises an ECU, a torque motor, a left drive straight gear, a right drive straight gear, a left drive bevel gear, a right drive bevel gear, a left driven bevel gear, a right driven bevel gear, a left torsion bar gear, a right torsion bar gear, a planetary gear, a left electromagnetic clutch, a planetary gear electromagnetic clutch and a right electromagnetic clutch. The running working conditions of a car are detected through the relative displacement sensor and the steering wheel angle sensor. The functions of unilateral active side roll prevention, double-side active side roll prevention and passive side roll prevention are achieved according to the side roll preventing requirements of the different running working conditions.

Description

Technical field [0001] The invention relates to the technical field of vehicle control, in particular to an electronically controlled separation type active anti-roll bar and an anti-roll method. Background technique [0002] The anti-roll bar is being used more and more as a vehicle driving safety auxiliary device, and the anti-roll capability it provides for automobiles has been well explored by people. However, the traditional anti-roll bar with a simple structure only uses its own torsion resistance to provide a reverse moment to the suspension to prevent roll, and the torsion resistance of the anti-roll bar becomes a relatively fixed one once installed on the car body. The size cannot reasonably adjust its own anti-roll capability according to the driving state of the vehicle. Anti-roll bars with too small torsional rigidity will cause excessive camber angles when cornering on an independent suspension car, reducing the tire contact area; anti-roll bars with too large torsi...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an electronically controlled separated active anti-roll bar and anti-roll The roll method changes the reverse torque of the left and right torsion bars of the anti-roll bar by controlling the voltage of the torque motor and the state of the electromagnetic clutch, so as to timely change the anti-roll capacity of the anti-roll bar and greatly improve the maneuverability of the car , stability and comfort
