The utility model discloses an operation control system of a pure-electric road-rail car. The system comprises a master control CPU, an energy supply and storage device, a cab control unit, an AC/DC bidirectional inverter, a voltage and current sensor and a rotating speed sensor, wherein the AC/DC bidirectional inverter and the voltage and current sensor are mounted on front and rear road-rail wheel pair motor assemblies. The beneficial effects of the invention are that the super capacitor with high power ratio is introduced as an auxiliary power supply to adapt to the working condition characteristics of high-power discharge and braking high-power recovery of heavy-load climbing when the road-rail car runs on a road; the power generation state operation of the traction motor in the railway mode is used for supplementing electric energy, so that the problem of low vehicle utilization rate caused by long-time standing charging of a traditional road-rail dual-purpose vehicle is solved, and the conversion between the railway operation mode and the road operation mode is realized by adopting the road-rail wheel pair motor assembly and the assistance of the axle changing box and the hydraulic lifting box.
