| 摘 要： | 以29自由度汽车动力学模型为基础,提出了保证线控汽车转向增益不变的稳态控制策略,使线控汽车转向特性不随车速和转向盘转角变化;提出了基于状态反馈的动态校正稳定性控制算法。仿真和驾驶模拟器实验表明,基于转向增益不变的稳态控制策略保证了汽车转向特性不变,减轻了驾驶员的负担,适合于更多的驾驶人群;基于状态反馈的动态校正稳定性控制算法有效提高了汽车的稳定性。

| Abstract: | Based on the 29-DOFs vehicle dynamic model,a steady-state control strategy based on constant steering gain and a dynamic correction stability control algorithm based on vehicle state feedback are proposed. The results of simulation and driving simulator test show that the steady-state control strategy can keep the steering gain of vehicle not change with vehicle speed and steering angle,hence reduce the driver's burden and is suitable for ordinary group of people;while the stability control algorithm can improve vehicle stability. |
