中文摘要：

针对汽车底盘关键子系统对侧翻运动影响能力及有效作用区域的差异，综合考虑了车辆运动耦合及轮胎力耦合因素，建立了包含悬架、制动和转向系统的11自由度整车侧翻动力学模型。以主动前轮转向、独立制动及主动悬架等底盘典型控制系统为对象，以系统的控制输入为分析变量，选取各系统对车体产生的侧倾修正力矩为权重评价依据，定量地研究了其对侧翻控制的功能权重及有效作用范围。结果表明，这三个控制子系统都可以在不同程度上有效地控制侧翻运动。分析明确了各系统工作的有效工作区域和控制权重，为车辆侧翻控制策略的制定提供了依据。

英文摘要：

Based on the comprehensive consideration of vehicle lyses of the differences of vehicle chassis key subsystems＇ kinematic coupling and tire-force coupling, and the ana- influences on vehicle rollover motion and effective acting regions, an eleven-DOF vehicle-rollover dynamic model taking account of the systems of suspension, braking and steering was constructed. The function weight and effective working areas of the chassis subsystems such as active front steer, single wheel brake and active suspension were analyzed under the circumstances that the corrective roll moments generated by the subsystems were chosen as the bases for evaluation of the control weight, and the subsystems＇ control inputs as the analysis variables. The results show that all the three control subsystems can effectively control the rollover movement to a different extent, and the effective working areas and control weight of the subsystems are identified and they are the bases for making the rollover control strategy.
