| 摘 要： | 准确简单的线控转向系统动力学模型是研究线控转向的各种控制策略和参数匹配的基础.建立了线控转向系统的人-车-路闭环动力学模型,包括道路模型、驾驶员模型、控制器模型、转向盘总成模型、整车模型(包括车身模型、轮胎模型)及前轮转向总成模型等.基于以上模型,研究了驾驶员模型参数:驾驶员的补偿转向增益和认知时间延迟引起的死区时间变化对实际侧向偏移到目标侧向偏移的传递函数频率响应的影响.结果表明,选择不同的参数对线控转向系统的操纵稳定性影响较大,应合理选择相关参数.

| Abstract: | Accurate and simple steer-by-wire system dynamic model is the basis for researching each control strategy and parameter match. Driver-vehicle-road closed loop dynamic models of steer-by-wire system are built, including road model, driver model, controller model, steering wheel assembly model, full vehicle model comprising of chassis model and tyre model,and front wheel steering assembly model and so on. Based on above models, effects of driver model parameters such as steering compensation gain and deadtime... |
