Abstract: A method and a system for detecting the state of a two-wheel balance vehicle are provided. The method comprises the following steps: S1, detecting pressure output by pedals of the two-wheel balance vehicle in real time after starting; S2, judging if the pressure increases; S3, if the pressure increase is greater than a predetermined half-load threshold value, switching into half-loaded state; and if the pressure increase is greater than a predetermined full-load threshold value, switching into fully-loaded state. Through the method and the system, getting on and off the vehicle becomes more convenient, effectively improving safety for drivers.
