The invention discloses a control method of an electric automobile and a control system; the control method includes steps of acquiring vehicle status and judging if the vehicle status meets the starting requirement; if the vehicle can start, sending a warning notice; acquiring the vehicle driving information, and judging if it meets the gear shifting requirement; if it is, sending a shifting request; otherwise, sending a voice notice; acquiring the shifting request and checking if it meets the shifting request; if it is, executing the shifting request; otherwise, sending the voice prompt. The control system comprises a vehicle starting module, a shifting judging request module, and a shifting verifying executing module. On the one hand, the method acquires the vehicle status before starting and judges if the vehicle meets the starting requirement, thus the vehicle driving safety is improved; on the other hand, the method acquires the vehicle driving information and judges if it reaches the shifting requirement during the driving process; meanwhile, the shifting requirement is verified so as to guarantee the shifting stability; the method and system are good for improving the shifting stability and reducing the power consumption in shifting.
