An adaptive Control strategy for hybrid control logic of a quarter-car is proposed in this paper, which makes better compliance between the handling and ride comfort. An algorithm for identifying road unevenness is abstracted via RMS of the suspension travel under variable road input and vehicle speed firstly, and then all optimal control parameters under different driving conditions are optimized off line by the H2 optimization. At last, the optimal control parameters are applied on an online control system, which demonstrates that the Adaptive Hybrid Control Strategy can improve the ride comfort in "soft" driving mode and handling stability in "sport" driving mode effectively.
