There is disclosed a control system for an electric motor vehicle in which individual inverters (20A, 20B, 20C, 20D) are provided in association with a plurality of ac motors (31A, 31B, 31C, 31D) for driving the vehicle, respectively. Respective inverters includes common control units (29) for effecting linkage control of respective inverters, thus to carry out an optimum adhesion control on the basis of a speed instruction for the vehicle and detected wheel diamters.
