PROBLEM TO BE SOLVED: To provide a travel control device which reduces a power loss and a generated heat amount by electric motors when an electric vehicle is turned.SOLUTION: A travel control device is applied to an electric vehicle in which right and left drive wheels are driven by respective electric motors. The travel control device of the electric vehicle, when a preset condition is satisfied S60, feedback-controls the electric motors such that actual rotation speeds of the electric motors becomes target rotation speeds based on a drive operation amount by a driver S100. The travel control device, when the preset condition is satisfied S60 and the electric vehicle is in a turning state S80, controls the electric motors so that the rotation speeds of the electric motors of the turing outer side wheels become the target rotation speeds and controls the electric motors so that drive torque of the turning inside wheels becomes target drive torque based on the actual drive torque of the electric motors of the turing outer side wheels S110-S130.SELECTED DRAWING: Figure 2
