摘要
在履带车辆行驶稳定性能的研究中,对比传统履带车辆结构形式,串联混合动力履带车辆的结构系统存在非线性特点,稳定性能很难保证。为了优化串联混合动力履带车辆的直驶稳定性能和转向性能,提出转矩调节控制策略;建立了驾驶员模型(包括加速踏板模型、制动踏板模型、方向盘模型)和整车动力学模型。根据驾驶员模型和整车动力学模型,采用转矩调节控制策略,在直驶加速、转向等工况下,进行了计算机仿真,结果表明转矩调节控制策略能有效的满足串联混合动力履带车辆的动力学需求。
The configuration of series hybrid electric tracked vehicle was analyzed.Compared with traditional tracked vehicle,the new configuration had new problem.In order to optimize the stability of linearly running and the steering performance of series hybrid electric tracked vehicle,the torque control strategy was proposed.The driver model（acceleration pedal model,decelerator model,steering wheel model） and dynamic mathematic model of the vehicle were established.Based on the analysis and simulation of the driver model and mathematic model of total control strategy,using torque control strategy,the tests of 0-32km/h acceleration,steering and a compound work station of the SHEV were done,and the performance curves were drawn.As a conclusion,the strategy is exact and effective.
