The invention provides an electric power steering system control method and a vehicle, and relates to the technical field of vehicles. The electric power steering system control method comprises the steps that the road surface type of a vehicle traveling path is recognized; when the road surface type is a characteristic road surface, determining assistance current according to the road surface type; and when the distance between the vehicle and the characteristic road surface is smaller than a corresponding preset distance threshold value, steering control is conducted according to the assistance current. Before the vehicle runs on the characteristic road surface, the road surface type of the vehicle traveling path can be pre-recognized, when the road surface type is the characteristic road surface, the power-assisted current is determined according to the road surface type recognized in advance, and when the distance between the vehicle and the corresponding characteristic road surface is smaller than the preset distance threshold value, steering control is conducted according to the power-assisted current. When a vehicle enters a characteristic road surface, instant vibration/impact cannot be caused, and the control comfort and safety of a driver are improved.

    本发明提供了一种电动助力转向系统控制方法及车辆,涉及车辆技术领域。本发明所述的电动助力转向系统控制方法,包括:识别车辆行进路径的路面类型;当所述路面类型为特征路面时,根据所述路面类型确定助力电流;当所述车辆与所述特征路面的距离小于对应的预设距离阈值时,根据所述助力电流进行转向控制。本发明可以在车辆开上特征路面之前,对车辆行进路径的路面类型进行预识别,当路面类型为特征路面时,根据提前识别的路面类型确定助力电流,当车辆与对应特征路面的距离小于预设距离阈值时,根据助力电流进行转向控制,使得车辆在进入特征路面时不会造成瞬间的振动/冲击,增加驾驶员操控舒适性和安全性。
