The invention provides a steer-by-wire system auxiliary control strategy considering driver steering characteristics based on a steer-by-wire dual-motor system, thereby realizing personalized auxiliary driving by young green-hand drivers, young skilled drivers and old drivers, and keeping steering styles of the young green-hand drivers, the young skilled drivers and the old drivers in the steeringprocess. On the basis of driver model parameter identification, steering characteristic parameters of a driver are obtained and used for designing a personalized auxiliary strategy. On the one hand,a driver can be individually assisted in a path tracking experiment, so that the tracking precision is improved, the tracking error is reduced; on the other hand, the physiological and psychological burdens of the driver can be reduced through auxiliary control, so that the optimal performance of the man-vehicle system is achieved. The personalized auxiliary control strategy gives full play to thepotential that the steer-by-wire system serves as an intelligent driving platform, the safety of the system is greatly improved, the driving feeling of a driver is improved, the driving style of thedriver is embodied, and wide development prospects and application value are achieved.

    本发明基于线控转向双电机系统提出了一种考虑驾驶员转向特性的线控转向系统辅助控制策略,可以对年轻的新手驾驶员,年轻的熟练驾驶员,老年驾驶员三类驾驶员进行个性化辅助驾驶,并在转向过程中保持他们的转向风格。基于驾驶员模型参数识别,获得驾驶员的转向特性参数,用于个性化辅助策略的设计。一方面可以个性化的辅助驾驶员进行路径跟踪实验,提高跟踪的精度和减小跟踪的误差,另一方面可以通过辅助控制减轻驾驶员的生理和心理负担,从而实现人‑车系统性能的最佳。个性化辅助控制策略充分发挥线控转向系统作为智能驾驶平台的潜力,极大的提高了系统的安全性,改善了驾驶员的驾驶感受,体现了驾驶员的驾驶风格,具有广阔的发展前景和应用价值。
