1. An electric four-wheel drive (4WD) system for a front wheel drive vehicle including an active roll control apparatus, the electric 4WD system comprising:
- a driving module configured to generate a rotational power using electrical energy and to supply the rotational power to rear wheels; and
a hydraulic generator, which is connected with the driving module, configured to generate a hydraulic pressure using the rotational power of the driving module and to supply the hydraulic pressure to the active roll control apparatus;
wherein the hydraulic generator comprises a pump connected to the driving module, and wherein the pump comprises;
a pump body of which a pump chamber is formed therein;
a rotation shaft rotatably mounted to the pump body, the rotation shaft receiving an output of the driving module; and
an impeller connected to the rotation shaft, the impeller generating a hydraulic pressure within the pump chamber.
