The invention provides a switching control method and device for the working modes of a blade electric vehicle. According to preset working mode deciding rules, the current working mode of the vehicle is determined. The working modes comprise the advancing mode, the energy recycling mode, the anti-slip mode, the peristaltic mode and the abrupt slope preventing mode. Switching rules between the advancing mode and other modes are preset, so that the vehicle is switched more smoothly between the advancing mode and other modes. According to the preset switching rules, when current running parameters meet the switching conditions, the vehicle is controlled to be switched to the target working mode from the current working mode, the problem that the torque fluctuates greatly in the switching process of the advancing mode and other modes, so that a driver feels uncomfortable is solved, the smoothness of the switching process is guaranteed, and the driving experience of the driver is improved.
