The invention relates to a predictive vehicle driving attitude control system based on an adjustable suspension and an intelligent driving system. The predictive vehicle driving attitude control system comprises an intelligent driving controller, a whole vehicle controller, a suspension height controller, a vehicle exterior environment information acquisition device, a vehicle running information acquisition device and a suspension adjusting device. The invention further relates to a vehicle predictive driving attitude control method based on the adjustable suspension and the intelligent driving system, and the method comprises a basic working condition predictive vehicle driving attitude adjustment strategy and a composite working condition predictive vehicle driving attitude adjustment strategy. The basic working conditions comprise a predictive uphill working condition vehicle driving attitude adjustment strategy, a predictive downhill working condition vehicle driving attitude adjustment strategy, a predictive left turning working condition vehicle driving attitude adjustment strategy, a predictive right turning working condition vehicle driving attitude adjustment strategy and a predictive acceleration working condition vehicle driving attitude adjustment strategy; a vehicle driving posture adjustment strategy under the predictive braking condition; the composite working condition is the superposition of two or more basic working conditions in time or space. The method is suitable for predictive active adjustment of the suspension of a vehicle equipped with an adjustable suspension and an intelligent driving system; the vertigo of passengers is relieved, and the driving comfort is improved; the vehicle stability is improved.

    本发明涉及基于可调悬架和智驾系统的预见性车辆行驶姿态控制系统,包含智驾控制器、整车控制器、悬架高度控制器、车外环境信息采集装置、车辆自身运行信息采集装置、悬架调节装置。本发明还涉及基于可调悬架和智驾系统的车辆预见性行驶姿态控制方法,包含基础工况预见性车辆行驶姿态调整策略和复合工况预见性车辆行驶姿态调整策略,基础工况包括预见性上坡工况车辆行驶姿态调整策略、预见性下坡工况车辆行驶姿态调整策略、预见性左转弯工况车辆行驶姿态调整策略、预见性右转弯工况车辆行驶姿态调整策略、预见性加速工况车辆行驶姿态调整策略、预见性制动工况车辆行驶姿态调整策略;复合工况为两种或两种以上的基础工况在时间或空间上的叠加。本发明适用于对装备有可调悬架和智驾系统的车辆进行悬架的预见性主动调节;减缓乘员眩晕感,提高驾乘舒适性;提高车辆稳定性。
