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.

The first distance calculation unit sets a braking force corresponding to a braking operation member operation amount as a reference braking force, estimates vehicle longitudinal acceleration based on the reference braking force, and calculates a braking force reference distance estimating a moving distance until the vehicle stops based on the longitudinal acceleration. The second distance calculation unit calculates a wheel reference distance estimating the vehicle moving distance based on a detection signal of the sensor and a wheel diameter. The braking control unit executes feedback control for controlling the vehicle braking force so that a difference between the braking force reference distance and the wheel reference distance decreases.
