The invention relates to a power-assisted steering mode control system and method.The system comprises an EPS controller, a large-screen IVI controller, an ESC controller, a driving mode module and a CDC system, and steering mode switching, driving mode linkage switching, self-adaption and IVI large-screen custom setting can be achieved. The method comprises the following steps that a steering mode is preset, and when switching conditions are met, a flag bit signal representing whether switching can be conducted or not is set to be allowed to be switched; the driving mode is preset, the actual steering mode of the vehicle is completely switched along with the driving mode after the association with the driving mode is selected in the IVI large screen, and the conventional independent switching process is executed after the association with the driving mode is cancelled; automatic switching, namely self-adaption, is realized; and setting the IVI large screen in a user-defined manner. According to the invention, different preset modes can be independently switched according to personal requirements; switching associated with the driving mode can also be set, and the steering mode is automatically switched according to different road surface feedbacks; and the user-defined steering hand feeling is also supported.

    本发明涉及一种转向助力模式控制系统及方法,系统包括EPS控制器、大屏IVI控制器、ESC控制器、驾驶模式模块和CDC系统,能实现转向模式切换、与驾驶模式联动切换、自适应和IVI大屏自定义设置。方法包括以下步骤:转向模式预置,当切换条件均满足时,表征是否可切换的标志位信号置为允许切换;驾驶模式预置,在IVI大屏中选中与驾驶模式关联后,车辆实际转向模式完全跟随驾驶模式而切换,取消选择与驾驶模式关联后,则执行常规独立切换过程;自动切换,即自适应;IVI大屏自定义设置。本发明可根据个人需求独立切换预置的不同模式;也可设置与驾驶模式关联切换,根据不同的路面反馈自动切换转向模式;还支持用户自定义转向手感。
