The invention discloses a calibration method and device for a brake pedal travel sensor, the calibration method for the brake pedal travel sensor can be applied to the technical field of vehicle braking, and the method comprises the steps that in response to an ignition instruction, offset data of the brake pedal travel sensor are obtained; first state information is obtained in the driving process of the vehicle, and when the first state information meets a first preset self-learning condition, dynamic self-learning is carried out with an offset parameter as a target based on the offset data and the first travel related data, and a dynamic learning result is obtained; in response to the flameout instruction, obtaining second state information; when the second state information meets a second preset self-learning condition, performing static self-learning by taking the offset parameter as a target based on the second travel related data to obtain a static learning result; and determining a target learning result based on the dynamic learning result and the static learning result, and updating the offset data. The accuracy of the offset data of the brake pedal travel sensor is improved.
