The invention provides an automobile eddy current retarder breaking heat energy recycling device and a control method, belonging to the field of automobile energy conservation and emission reduction technology. A large amount of low-grade heat energy produced in the braking process of a permanent-magnet retarder used in a heavy truck is recycled into electric energy by using organic Rankine cycle, the produced electric energy is used for catalytically reforming methanol aqueous solution, and the produced reformed gas is introduced into an intake pipe of a diesel engine and mixed with diesel oil for combustion. As the diesel engine is in idling and has poor combustion condition when an automobile uses a retarder; working medium exhaust gas produced after an expander does work is used in the invention to heat the inlet gas of the diesel engine so as to improve the combustion of the diesel engine and reduce emission. Through comprehensive effects of an organic Rankine cycle generating system, a methanol aqueous solution catalytic reforming device, a diesel engine inlet air heating device and a control system, the device and control method provided by the invention recycle the braking heat of the retarder, ensure reliable work of the retarder, improve the combustion and emission performance of the diesel engine in idling, and realize energy conservation and emission reduction of the diesel engine.
