The invention provides a vehicle suspension control method and a vehicle suspension controller. The vehicle suspension control method comprises the following steps that whether a vehicle is in an impact working condition or not is judged; if yes, obtaining a single impact damping force and a damping correction coefficient when the front axle shock absorber passes through the impact position, and calculating to obtain a rear axle pre-control damping force through the single impact damping force and the damping correction coefficient; the driving mileage of the vehicle is obtained; judging whether the driving mileage exceeds a threshold value or not; and if yes, the damping force of a rear axle shock absorber is controlled to be the rear axle pre-control damping force. According to the method, the complex road working condition can be considered in inter-axle predictive control, it is guaranteed that the vehicle can pass through the impact working condition in the optimal state, and the driving comfort and controllability are greatly improved.
本发明提供一种车辆悬架控制方法及车辆悬架控制器,包括如下步骤:判断车辆是否处于冲击工况;若为是,获取前轴减振器通过冲击位置时的单项冲击阻尼力和阻尼修正系数,并通过所述单项冲击阻尼力和所述阻尼修正系数计算得到后轴预控阻尼力;获取车辆的行驶里程;判断所述行驶里程是否超过阈值;若为是,将后轴减振器的阻尼力控制为所述后轴预控阻尼力。该方法能够在轴间预测性控制中考虑复杂的道路工况,保证车辆能够以最优状态通过冲击工况,大幅提升驾驶的舒适性和操控性。
