The invention relates to a cabin parameter optimization method and system for improving the sitting posture comfort of a driver, and relates to the technical field of automobile cabin comfort optimization. The minimum sum of distances between all driving sitting posture joint angles in a selected current group of comfortable joint angles and corresponding comfortable interval boundary values is used as an objective function; a set cabin parameter range is used as a constraint condition, a cabin parameter optimization model is constructed and solved, a cabin parameter optimal value is obtained, whether the corresponding driving sitting posture joint angle meets the comfort expectation or not is verified by using the cabin parameter optimal value in turn, cabin parameter adjustment amount optimization is performed, and while the cabin parameter adjustment amount is ensured to be as small as possible, the driving sitting posture joint angle can be accurately adjusted. According to the scheme, the number of the sitting posture joint angles of the driver in the comfort interval is as large as possible, a brand-new guidance optimization mode is provided for improving the sitting posture comfort of the driver, and compared with the current research on the driving sitting posture comfort only stays at the sitting posture comfort evaluation stage, the scheme more flexibly meets the actual requirements of automobile cabin development engineering.
本发明涉及一种提升驾驶员坐姿舒适性的座舱参数优化方法及系统,涉及汽车座舱舒适性优化的技术领域,以选定的当前组舒适关节角中所有驾驶坐姿关节角与其对应的舒适区间边界值的距离总和最小为目标函数,以设定的座舱参数范围为约束条件,构建座舱参数优化模型并求解,到座舱参数最优值,利用座舱参数最优值反过来校验其对应的驾驶坐姿关节角是否符合舒适预期,再进行座舱参数调整量优化,在保证座舱参数调整量尽可能小的同时,驾驶员坐姿关节角处于舒适区间的数量尽可能多,为提升驾驶员坐姿舒适性提供了全新的指导优化方式,相较于当前对驾驶坐姿舒适性的研究仅停留于坐姿舒适性评估阶段,本方案更加灵活地适配汽车座舱开发工程实际需求。
