The invention belongs to the technical field of automobile electric control, and discloses a steering wheel corner signal output method which comprises the steps that a first signal and a second signal are obtained, the first signal is a corner signal of a steering motor rotor, and the second signal is a corner signal of a steering gear input shaft; judging whether the first signal is credible or not, and if yes, taking the first signal as a steering wheel angle signal and outputting the signal; and if not, continuing to judge whether the second signal is credible, if so, taking the second signal as a steering wheel angle signal and outputting, and if not, taking the previous frame of data of the current second signal as the steering wheel angle signal and outputting, and gradually reducing the subsequently output steering wheel angle signal to 0. The steering wheel angle signal output method provided by the invention is simple in steps, simplifies the component structure, effectively improves the reliability and accuracy of steering wheel angle signal output, and improves the driving safety.

    本发明属于汽车电控技术领域,公开了一种方向盘转角信号输出方法,其包括:获取第一信号和第二信号,第一信号为转向电机转子的转角信号,第二信号为转向器输入轴的转角信号;判断第一信号是否可信,若是,则以第一信号作为方向盘转角信号并输出;若否,则继续判断第二信号是否可信,若是,则以第二信号作为方向盘转角信号并输出,若否,则按照当前第二信号的前一帧数据作为方向盘转角信号并输出,且随后输出的方向盘转角信号逐渐减小到0。本发明提供的方向盘转角信号输出方法,步骤简单,简化部件结构,有效提升方向盘转角信号输出的可靠性和准确性,提升行车安全性。
