Electronic Active Suspension System Development with Driverīs Motion Analysis
In recent years, vehicle attitude control is one of the main issues in vehicle stability and safety sides of views. Active stabilizer system, control vehicle roll angle by an actuator, is known as a major system and is widely used. The actuator is mounted in the same axis of stabilizer and it leads the stabilizer to twist for the control.
The objective of the report is to introduce future development of rotary type electric active suspension that provides a way for directional control of vehicle roll, pitch, and bounce. The system allows controlling vehicle motion and gives driving comfort by inertial inputs controlling and skyhook controlling at every road input.
The actuator developed based on active stabilizer system actuator. The required performance was calculated by estimating effects for vehicle performance and response of actuator. The resulted performance was tested by actual vehicle and it was satisfied.
For the control system, low energy consumption with driving comfort was achieved by re-sets skyhook control and examines insured logic for actuator delay.
Driverīs dynamic characteristic is another important issue to be concentrated. The effects of vehicle motion control for drivers were investigated and vehicle attitude control based on human characteristic was also investigated.
