The invention provides a downhill retarder control device of a dual-power gearbox. The device comprises an air storage cylinder, a three-position two-way foot valve, a brake switch, a signal switch converter and two sets of air cylinders, the three-position two-way foot valve is installed in a cab, an air inlet of the three-position two-way foot valve is communicated with the air storage cylinder, a working port is communicated with air inlets of two air cylinders through a tee joint, an exhaust port of the three-position two-way foot valve is connected with an exhaust pipe, the brake switch and the signal switch converter are sequentially arranged on a connecting pipeline of the three-position two-way foot valve and the air cylinders, the brake switch is connected with a vehicle central control system, the signal switch converter is connected with a vehicle ABS system, and the output ends of the two air cylinders are respectively connected with a retarder executing mechanism on the dual-power gearbox. The downhill retarder control device of the dual-power gearbox is simple in pipeline connection and convenient to operate by a user, and the braking efficiency of a downhill retarder can be exerted to the maximum extent.
