The invention provides an engineering truck, a double independent driving system and a control method of the double independent driving system. The double independent driving system comprises a first terminal retarding mechanism, a second terminal retarding mechanism, a first rigid gear shaft meshed with the gear of the first terminal retarding mechanism, a second rigid gear shaft meshed with the gear of the second terminal retarding mechanism, a clutch with two ends connected with the first rigid gear shaft and the second rigid gear shaft respectively, and a control component connected with the clutch and used for controlling the engaging and disengaging of the clutch. When the clutch is engaged, the terminals of the two driving systems of the double independent driving system are in rigid connection with each other; when the clutch is disengaged, the terminals of the two driving systems rotate independently, so as to ensure normal operation of the engineering truck, and prevent the engineering truck from de
