The present invention provides a driving system for an electric vehicle which solves a problem of transmission shock, and a control method thereof. The driving system for an electric vehicle comprises: a motor; a transmission module configured to receive power of the motor and implement a plurality of transmission stages by using a plurality of circumscribed external gear pairs; a clutch installed to intermittently supply the power of the motor to the transmission module; a transmission lever provided to sequentially select a plurality of designated positions which are discontinuously disposed; a position detection sensor installed to detect a displacement in which the transmission lever sequentially moves the designated positions as a continuous change in physical quantity; a clutch actuator provided to drive the clutch; a transmission actuator installed to implement transmission of the transmission module; and a controller receiving a signal from the position detection sensor and controlling the clutch actuator, the transmission actuator and the motor to perform the transmission.
