The invention discloses a brake pedal strength analyzing system. The brake pedal strength analyzing system comprises a hydraulic cylinder, a pedal travel sensor, a pedal, an ECU (electronic control unit), a pressure sensor, an oil inlet electromagnetic valve, an oil outlet electromagnetic valve, a high-pressure accumulator and an oil cup. The working rod at one end of the hydraulic cylinder is connected with the pedal, and the other end of the hydraulic cylinder is connected with the oil inlet electromagnetic valve through a first branch; the oil inlet electromagnetic valve is connected with the oil cup through a third branch; the other end of the hydraulic cylinder is connected with the oil outlet electromagnetic valve through a second branch; the oil outlet electromagnetic valve is connected with the oil cup; the high-pressure accumulator is connected with the third branch; the pedal travel sensor is connected with the pedal; the ECU computes the internal reference pressure of the hydraulic cylinder according to the signals of the pedal travel sensor and the ideal relation curve between pedal force and pedal travel, and then compares the reference pressure with the practical measured value of the sensor so that the internal pressure of the hydraulic cylinder can automatically and rapidly trace change of reference values.
