Abstract: Aiming at the problems of vehicle active stabilizer in structure design, power drive and control strategy, the working principle of active stabilizer was summarized and analyzed, the research status of active stabilizer at home and abroad was expounded in depth, and a summary with theoretical guiding significance was given. Firstly, the structural forms of active stabilizer bars at home and abroad were analyzed, and the applicable occasions of different types of active stabilizer bars were summarized. Secondly, the lightweight of active stabilizer bars was analyzed, and the research progress and application of lightweight of active stabilizer bars at home and abroad were discussed. Finally, a detailed overview of the active stabilizer bar was given, and the existing problems in the research of the active stabilizer bar and the direction to be further studied were summarized. The results show that the research on the lightweight design of active stabilizer rod, the optimization of control strategy and the improvement of system robustness are still valuable.
