The invention discloses a brake pedal displacement detection device and a brake pedal displacement detection method. The detection device comprises a pedal feeling simulation unit and a pedal displacement detection unit; the pedal feeling simulation unit comprises a pedal, an input rod, a booster, a piston, a cylinder body, a first spring, a second spring, a flow guide pipe and a pressure sensor,the middle of the pedal is connected with one end of the input rod, the upper end of the pedal is connected with the piston, the booster is connected with the other end of the input rod, the piston isarranged in the cylinder body, the two ends of the piston are connected with the two ends of the cylinder body through the first spring and the second spring respectively, and the pressure sensor isinstalled on the flow guide pipe; the pedal displacement detection unit comprises an oil tank and a weighing sensor, and the weighing sensor is arranged at the bottom of the oil tank; and one end of the cylinder communicates with the oil tank through the flow guide pipe. The device is mounted outside the booster, so that a mechanical structure coupled with the booster can be simplified; and pedaldisplacement can be obtained indirectly to control vehicle dynamics.
