Abstract
Systems and methods for detecting wheel speed are provided. An electric circuit for detecting a speed of a wheel may comprise: a transducer in electronic communication with an operational amplifier (OP-AMP), the transducer configured to output a variable signal in response to an angular velocity of a rotatable member of a wheel assembly; a constant voltage source in electronic communication with the OP-AMP; and a sensor in electronic communication with an output terminal of the OP-AMP configured to monitor an output signal of the OP-AMP, the output signal including a period; and a controller configured to receive the output signal and configured to calculate the speed of the wheel according to a pre-determined ratio of the wheel speed and the period. In various embodiments, the circuit may allow for slow wheel speed detection.
