The invention discloses a virtual calculation method and device for a steering absolute angle of an electric steering engine and relates to the technical field of automobiles. In the invention, a virtual steering wheel absolute turning angle value is obtained through parameter interaction and calculation between a controller and a vehicle body stability controller; a steering wheel turning angle sensor is replaced; and a real-time absolute value of a collision angle of a steering wheel can be obtained without installing the steering wheel turning angle sensor in an automobile adopting the scheme, manufacturing cost of the whole automobile is saved, complexity of a whole system is reduced, and meanwhile an assembling space is saved.
本发明公开了一种电动转向机转向绝对角度虚拟计算方法及装置,涉及汽车技术领域,本发明通过向控制器和车身稳定控制器之间的参数交互及计算得到虚拟的方向盘绝对转角值,替代方向盘转角传感器,实施了该方案的车辆可以不安装方向盘转角传感器获取到方向盘撞角实时的绝对值,节约了整车制造成本,降低了整个系统的复杂度,同时节省了装配空间。
