An electric active stabilizer suspension system has been developed as a technology for controlling vehicle roll. This paper describes the design of the active stabilizer suspension system, focusing on the required actuator performance that was set based on real-world use conditions and reduction gear reverse efficiency. The roll angle was used as an evaluation index in the development of a vehicle equipped with the active suspension. Based on the results of roll attitude angle and a subjective evaluation, a target roll angle of 1 degree for a lateral acceleration of 5 m/s2 was set. The system includes various sensors that detect the vehicle's running state, and active stabilizer actuators that use electric motors and reduction gears to control roll. The electric stabilizer suspension system was compared with hydraulic stabilizer systems, and an investigation demonstrated the superiority of the developed system, which offers outstanding vehicle behavior, improved responsiveness and reduced energy consumption (including energy regeneration). Average energy consumption was reduced to 8.8 W, which is approximately 1/20 that of a hydraulic system.
