AB - Three different control cases in control air suspensions using air springs controlled (ASC), (2) using the damper controlled (DC), and (3) using both ASC and DC (ASDC) are proposed to ameliorate both riding quality and friendliness-road surface of heavy vehicle based on the heavy vehicle’s dynamic model and fuzzy logic control with its control rules optimized by genetic algorithm. The riding quality and friendliness-road surface are assessed through the root-mean-square cabin accelerations (awzc and awϕc) and coefficient of the dynamics load (CDLn) at wheel axles. Research shows that the vehicle’s riding quality and friendliness-road surface are strongly affected by the moving speed and road surface roughness. The awzc, awϕc, and CDLn of the control air suspensions are strongly decreased compared to passive air suspensions, particularly with ASDC. Additionally, awzc and awϕc of DC are smaller than that of ASC whereas the maximum CDLn with DC is higher than that of ASC. Thus, DC could be used for improving vehicle’s riding quality, ASC should be applied for ameliorating vehicle’s friendliness-road surface, and ASDC should be applied for ameliorating both riding quality and friendliness-road surface of heavy vehicles.
