The four-salient-pole double-coil eddy current braking device for the vehicle is characterized in that double stators are arranged on the outer side of a connecting shaft of the braking device, the double stators comprise an inner stator and an outer stator, a four-salient-pole rotor is arranged between the inner stator and the outer stator, a supporting reinforcing rib is arranged in the middle of the position between the inner stator and the outer stator, and the four-salient-pole rotor is connected with the supporting reinforcing rib. Water channels are arranged in the inner stator and the outer stator, coils are arranged on the two sides of the supporting reinforcing ribs, four-salient-pole rotors are arranged on the outer sides of the coils, the coils, the four-salient-pole rotors and the connecting shaft are concentric and coaxial, a double-stator four-salient-pole structure is adopted, water channels are arranged in the stators corresponding to the four salient-pole rotors, and a double-coil structure is adopted. The excitation efficiency is high, the brake torque of the retarder in unit volume is improved, manufacturing and assembling are easy, stepless adjustment of the brake torque is easy to achieve, and intelligent control and cruise control are easy to achieve due to the fact that a CAN bus is adopted to be connected with a vehicle control unit.
