The invention discloses a hydraulic retarder control device and method based on a switch type electromagnetic valve. The device comprises two air inlet electromagnetic valves, two exhaust electromagnetic valves, a safety electromagnetic valve, an air pressure sensor and a control handle. The air inlet ends of the two air inlet electromagnetic valves are connected with an air source, and the air outlet ends are connected with the hydrodynamic retarder; the air inlet ends of the two exhaust electromagnetic valves are connected with the air outlet ends of the two air inlet electromagnetic valves through air paths; the air inlet end of the safety electromagnetic valve is connected with the air outlet ends of the two air inlet electromagnetic valves through air paths and connected with the air inlet ends of the two exhaust electromagnetic valves at the same time. Pressure sensors are arranged between the hydraulic retarder and the two air inlet electromagnetic valves and between the hydraulic retarder and the two air outlet electromagnetic valves; the two air inlet electromagnetic valves, the two exhaust electromagnetic valves and the control handle are all connected with the hydraulic retarder controller through connectors; and the air pressure sensor is connected with the hydraulic retarder controller. The invention has the advantages of fast response, low cost, high control precision, long service life, safety, stability and reliability.
