Vehicle wheel speed and acceleration sensor and method for calculating the same |
摘要 |
Systems and/or methods for detecting a rotating wheel's speed and/or acceleration are provided. A sensor is attached to the rotating wheel. The sensor includes a circuit (e.g. a Wheatstone bridge circuit) having a plurality of resistors (e.g. 4 resistors). Each resistor includes a giant magnetoresistance (GMR) element and has a resistance changeable based at least in part on a change in magnetic field intensity with respect to an external magnetic field. The sensor generates a signal based at least in part on the resistors' resistances. A processor is operable to calculate the rotating wheel's speed and/or acceleration based at least in part on the signal.
