Assignee: HITACHI ASTEMO, LTD.
Field: Measurement (Instruments)
Classification: CPC B  G | IPC B  G

Claim 0:
1. A vehicle pedal stroke detection apparatus comprising:
a magnet configured to be displaced in an axial direction according to a movement of a rod that moves in the axial direction based on an operation on a pedal;
a stroke sensor configured to detect a physical amount regarding a magnetic flux of the magnet; and
a control unit,
wherein the control unit
acquires the physical amount regarding the magnetic flux of the magnet that is output from the stroke sensor, and acquires a first value based on the acquired physical amount regarding the magnetic flux of the magnet, the first value being a physical amount regarding a magnitude of a magnetic flux density of the magnet with respect to the displacement of the rod, and
compares the first value and a second value, the second value being a physical amount regarding the magnitude of the magnetic flux density of the magnet with respect to the displacement of the rod, the magnitude of the magnetic flux density of the magnet with respect to the displacement of the rod for the second value being preset.
