摘　　要：提出了基于角度传感器检测量程与游标原理算法检测量程为周期的分段函数算法。与传统非接触式方向盘转角传感器游标原理算法进行了对比分析,并对其角度检测范围与分辨率等方向盘转角传感器指标进行了验证。搭建了角度试验台架以及相应的方向盘转角传感器样机。台架试验表明:该算法提高了方向盘转角传感器的检测精度,实现了其检测量程与检测精度的解耦,为实现更高的控制精度与可靠性提供了可能。The piecewise function algorithm based on the cycle of angular sensor detection range and vernier principle algorithm detection range was proposed. The algorithm was compared with the traditionalnon-contact vernier algorithm, and the steering wheel angle sensor indicators of the angular velocity detection range, resolution and so on were verified. The experimental prototype of the steering wheel angle sensor was set up. The bench test shows that the piecewise function algorithm improves the detectionprecision of the steering wheel angle sensor, realizes the decoupling between the detection range and the detection precision, and makes it possible to realize higher control accuracy and reliability.
