Abstract: A vehicle pedal stroke detection apparatus acquires a first value based on a physical amount regarding a magnetic flux of a magnet that is output from a stroke sensor. The first value is a physical amount regarding a magnitude of a magnetic flux density of the magnet with respect to a displacement of a push rod. Then, the vehicle pedal stroke detection apparatus compares the first value and a second value. The second value is a preset physical amount regarding the magnitude of the magnetic flux density of the magnet with respect to the displacement of the push rod.
