Vehicle stabilizer bar and its control method based on adjustable inertial mass

Abstract

The invention discloses an automotive horizontal stabilization rod based on adjustable inertia mass and a control method of the automotive horizontal stabilization rod. The automotive horizontal stabilization rod is characterized in that a damper capable of adjusting inertia quality is a cylinder, a left end cover and a right end cover are closed at two ends of a cylindrical shell to form the cylinder, the left end cover is fixedly connected with a left side rod, an output end of a center shaft of the damper convexly extends from the right end cover and is fixedly connected with a right side rod to form the automotive horizontal stabilization rod, torsion angles and damping force are generated between the left side rod and the right side rod by the damper when the left side rod and the right side rod twist, rotating output of an inertia mass adjusting mechanism in the damper provides driving force for a power generation mechanism and generates electric energy, attributes of magneto-rheological fluids are changed by the aid of semi-active control, output characteristics of the damper are adjusted, so that automotive horizontal stabilization rod performance is adjusted, torsion rigidity of the automotive horizontal stabilization rod can be adjusted, and tilting safety and comfort of an automobile can be improved.

Description

technical field [0001] The invention relates to an automobile lateral stabilizer bar based on adjustable inertial mass and a control method thereof, belonging to the technical field of vehicle safety and comfort. Background technique [0002] The stabilizer bar is an auxiliary elastic component in the automobile suspension system. Its function is to prevent the body from generating excessive roll angles when turning, the purpose is to prevent the car from laterally tipping, improve the driving safety of the car and improve the ride comfort. The single torsional stiffness of the traditional stabilizer bar makes the anti-roll adjustment range of the stabilizer bar limited, and it is often difficult to meet the requirements of various working conditions of the vehicle, and the anti-roll performance of the stabilizer bar cannot be adjusted according to the working conditions. Especially when the car is under the condition of large lateral acceleration, the large body roll angle...
