Abstract

The invention relates to a control system and a control method for a vehicular active stabilizing bar. The control system comprises a lateral acceleration sensor, a piston displacement sensor, an inclinometer, a control unit and a signal output executing mechanism, wherein the signal output executing mechanism comprises a hydraulic unit and a piston. The control method comprises the following steps: confirming a series of control rules according to the following three control parameters: lateral acceleration, piston displacement and heeling angle, and then implanting the control rules into the control unit; acquiring a specific vehicle driving state by the control unit according to the combination of the three control parameters; selecting corresponding confirmed control rules according to different driving states; and confirming if changing the piston displacement and confirming the volume of the changed piston displacement. An active stabilizing bar control system adopting the control method provided by the invention has simpler structure, is suitable for all vehicles and is used for ensuring the safer and more comfortable driving of the vehicle.

Description

technical field [0001] The invention relates to a control system and a control method of an active stabilizer bar for a vehicle, belonging to the technical field of vehicle electronics. Background technique [0002] The control law of the vehicle active stabilizer bar system refers to the law that the piston displacement changes with the parameters at all times. The main research is to choose what parameter to control and when to change the piston displacement. [0003] At present, there are no automobile companies in China that manufacture active stabilizer bar systems, and they do not have the ability to independently develop them. The stabilizer bars of domestic cars are generally passive, and the ability of this type of stabilizer bar in anti-roll is very limited, especially for For off-road vehicles with a large degree of roll, the passive stabilizer bar is even more difficult. Therefore, in terms of safety and comfort, it is far from meeting the requirements of active...
