| Abstract: | In order to achieve pressure fine regulation for integrated chassis control,the operating mechanism principle of hydraulic brake system and the regulating characteristics of wheel cylinder pressure were analyzed.Pressurization and decompression experiments were carried out on the hydraulic test platform.A hydraulic brake pressure estimation based on 3-D data sheet was suggested.Comparison experiments verified this method with a satisfactory exactitude on both open-loop and closed-loop conditions. |
