This paper presents an advanced integrated control system comprising the benefits of anti-lock brake system (ABS) and slow-active suspension system. A linear optimization technique is followed to improve the ride dynamics in terms of suspension working space, body vertical acceleration and tire dynamic normal load. The ABS controller regulates theapplied barking pressure to maintain the tire skid ratio within the desired range. The presented investigation is applied to a quarter car model embracing an idealized limited bandwidth actuator in series with a suspension spring. This combination is further integrated with hydraulic circuit to modulate the braking pressure. The mathematical derivation isnumerically solved using MATLAB package. Several simulation results are carried out considering typical performance measures such as stopping time, stopping distance and body vertical acceleration. The proposed design of the slow active suspension controller is suitable for both the ride vibration and brake performance which are widely applied in modernvehicles. |
