。Changes in the magnetic field during the rotation of a permanent magnet connected to a shaft that is synchronized with the rotation of the drive shaft in a vehicle
By applying another two-terminal voltage, a change in resistance value at the junction of at least one pair of magnetoresistive elements located near the permanent magnet is captured as a voltage change, and based on this voltage change, the permanent magnet is In a vehicle speed sensor that detects the rotational speed of a magnet, one comparator is used to detect the voltage change at the junction point of the pair of magnetoresistive elements, and the side input of this comparator is used to compare the voltage change with the comparator output. A vehicle speed sensor characterized in that the voltage change is passed through a first-order lag element and inputted to one side input of the comparator.
