The invention relates to a vehicle steering characteristic adjusting method and system, and the method comprises the following steps: obtaining the wheel load data of a vehicle, and calculating the current steering characteristic of the vehicle through the wheel load data; the target steering characteristic of the vehicle is obtained, the current steering characteristic is compared with the target steering characteristic, and the target load transfer amount W is obtained; according to the corresponding relation between the load transfer amount and the rigidity of the anti-roll bar, the target rigidity of the anti-roll bar is calculated; and the rigidity of the anti-roll bar is adjusted based on the target rigidity, so that the transferred load capacity is the load transfer capacity W. Compared with the prior art, the method has the advantages that the wheel load data serve as input, the front and rear axle load ratio parameter is adjusted by adjusting the rigidity of the anti-roll bar to control the steering characteristics of the vehicle, a new control strategy is provided, wheel load input is more direct, and the motion characteristics of the vehicle can be better reflected.
本发明涉及一种车辆转向特性调节方法及系统,方法包括以下步骤:获取车辆轮荷数据,利用所述轮荷数据计算车辆的当前转向特性;获取车辆的目标转向特性,将当前转向特性与目标转向特性进行比较,得到目标的载荷转移量W;根据载荷转移量与防倾杆刚度的对应关系,计算防倾杆的目标刚度;基于目标刚度调整防倾杆的刚度使得转移的载荷量为载荷转移量W。与现有技术相比,本发明利用轮荷数据作为输入,通过调整防倾杆刚度调整前后轴载荷比参数控制车辆的转向特性,提出了一种较新的控制策略,且轮荷输入更为直接,更能反应车辆的运动特性。
