The invention discloses a vehicle driving comfort improving method and system. The method comprises the following steps that the longitudinal acceleration in the vehicle driving process is obtained; according to the obtained longitudinal acceleration, the expected point rising working condition in front of the vehicle is obtained; and for the expected point-up working condition in front of the vehicle, the point-up of the vehicle is restrained by adjusting the rigidity of the active suspension. According to the vehicle driving comfort improving method provided by the invention, the point head-up working condition in the vehicle driving process is restrained by controlling the rigidity of the suspension, the influence of the hardness of the suspension is avoided, and the vehicle driving comfort is effectively improved; the method is suitable for point and head raising control in the driving process of vehicles with suspension systems of different hardness degrees. Under the braking working condition, vehicle deceleration does not need to be changed or braking pressure does not need to be increased, and the vehicle braking stroke is not affected.
本申请公开了车辆驾驶舒适性提升方法及系统,所述方法包括如下步骤:获取车辆行驶中纵向加速度;根据获取的纵向加速度,获取车辆前方预期出现的点抬头工况;针对车辆前方预期出现的点抬头工况,通过调整主动悬架的刚度抑制车辆的点抬头。本申请提供的车辆驾驶舒适性提升方法,通过控制悬架刚性大小抑制车辆驾驶中点抬头工况,不受悬架软硬影响,有效提升车辆驾驶舒适性;适用于不同软硬程度的悬架系统的车辆进行驾驶过程中的点抬头控制;制动工况下,无需改变车辆减速度或增加制动压力,不影响车辆制动行程。
