Research on four-wheel steering stability of hybrid electric vehicle based on elastic drive feedback adjustment

为解决目前混合动力汽车四轮转向操纵稳定性较差的问题,提出一种基于弹性驱动反馈调节的混合动力汽车四轮转向操纵稳定性控制方法。首先通过分布在传感网络中的传感器,采集混合动力汽车四轮转向物理参数,以采集参数为约束模型,构建汽车四轮转向的力平衡方程。然后在力平衡环境中,对混合动力汽车四轮转向的运动空间进行联合规划识别,构建四轮转向的运动状态模型。最后采用运动状态模型调节汽车四轮转向的刚体独立性,修正力学参数,获取四轮转向运动控制输出惯性力矩,结合模糊搜索方法进行混合动力汽车四轮转向的多模式驱动力学稳定性调节。实验结果表明,采用所提方法进行混合动力汽车四轮转向操纵的稳定性较好,转向的操纵误差修正能力较强,整体更具有应用优势。

Aiming at poor four-wheel steering stability of hybrid electric vehicle(HEV),it presents a four-wheel steering stability control method of hybrid electric vehicle(HEV)based on elastic drive feedback regulation.Using sensors distributed in sensor networks,it collects the four-wheel steering physical parameters of the hybrid vehicle,takes the parameters as the constraint model,and builds the force balance equation of the four-wheel steering of the automobile.Based on the joint planning and the motion state model of four-wheel steering,it identifies the force balance environment,the motion space of four-wheel steering of hybrid vehicle.It adopts the motion state model to adjust the independence of the rigid body of the four-wheel steering of the automobile,and corrects the mechanical parameters,acquires the output inertia moment of the four-wheel steering motion control,and realizes the multi-mode driving mechanical stability adjustment of the four-wheel steering of the hybrid vehicle with the fuzzy searching method.The results show that the proposed method has better stability for the four-wheel steering of hybrid vehicles,and the steering error correction ability is stronger,and the overall has application advantages.
