侧风作用下货车驾驶员反应行为模型

Model of Driving Behavior of Truck Driver Under Crosswind

摘要:

为建立侧风作用下驾驶员反应行为模型，基于8自由度驾驶模拟器，构建了风-车-桥耦合作用下大跨桥梁驾驶模拟平台。招募了32名职业货车驾驶员进行了侧风作用下驾驶模拟实验，采集了驾驶员行为及车辆动态响应数据，通过相关性分析选取了关键因素，建立了侧风作用下两阶段驾驶员反应行为模型。研究结果表明：方向盘反馈力矩是影响侧风作用下驾驶员反应行为的关键因素之一；考虑方向盘反馈力矩在内的两阶段模型能够较好的反映侧风作用下驾驶员的反应行为。

Abstract:

In order to establish the driver behavior model under the action of crosswinds, a driving simulation platform for long-span bridge under the action of wind-vehicle-bridge coupling was built based on the 8-dof driving simulator. Thirty-two professional truck drivers were recruited to conduct driving simulation experiments under crosswinds. Driver behavior and vehicle dynamic response data were collected and a two-level driver behavior model was established under crosswind. The results show that the steering wheel torque feedback is one of the key factors affecting the driver behavior under crosswind. Considering the steering wheel torque feedback, the two-level model can better reflect the driver behavior under the action of crosswind.
