轮速估计系统和方法
摘要：
一种估计通过机械地耦合到在车辆(10)上的至少一个车轮以便旋转所说的一个或多个车轮的直流马达(14)推动的车辆(10)的轮速的系统和方法。至少一个电流检测器被构造成测量在每个直流马达(14)中的场电流和电枢电流并形成与所说的电流成比例的信号和电压检测器被构造成测量施加到每个直流马达(14)的电压并形成与所说的电压成比例的信号。处理器被构造成确定作为所测量的电流和电压的函数的转速并被构造成将校正系数应用到所确定的转速中以获得经校正的转速。
摘要（英）：

A system for estimating wheel speed consists of current detector for measuring field current and armature current of each DC motor and forming signal in proportion to said current, voltage detector for measuring voltage exerting on each DC motor and forming signal in proportion to said voltage, processor for confirming rotary speed as function of measured voltage and current and applying calibration coefficient on confirmed rotary speed to obtain calibrated rotary speed.
