The invention discloses a vehicle manipulation stability intervention method and system with driving style adaptability, and belongs to the technical field of vehicle manipulation control. The method comprises the following steps: constructing a'vehicle front wheel steering angle-longitudinal speed 'steady-state reachable domain based on a vehicle dynamics model, linear/nonlinear critical lateral acceleration and road adhesion limit constraint; classifying vehicle lateral response styles based on the collected driving data, and extracting feature lateral acceleration maximum values of different styles after classification; taking the obtained characteristic lateral acceleration reflecting different driving styles as a constraint condition of a constructed steady-state reachable domain, solving a corrected steady-state reachable domain model, and obtaining a personalized steady-state reachable domain; a K-means method is adopted to construct a driving style recognition model, a steady-state reachable domain corresponding to the driving style is selected based on real-time driving data, and the stability of the vehicle under the driving style is judged online, so that the stability of the vehicle can be visually and quickly judged at an input end.
本申请公开了一种具有驾驶风格适应性的车辆操纵稳定性介入方法及系统,属于车辆操纵控制技术领域。该方法基于车辆动力学模型和线性/非线性临界侧向加速度、路面附着极限约束构建“车辆前轮转角‑纵向速度”稳态可达域;基于采集的驾驶数据对车辆侧向响应风格进行分类,并提取分类后的不同风格的特征侧向加速度最大值;将得到的反应不同驾驶风格的特征侧向加速度作为构建的稳态可达域的约束条件,求解修正后的稳态可达域模型,获得个性化稳态可达域;采用K‑means法构建驾驶风格识别模型,基于实时的驾驶数据选择对应驾驶风格的稳态可达域,在线判别此驾驶风格下车辆的稳定性,从而可以直观且快速的在输入端判断车辆稳定性。
