The invention discloses an emergency control hydraulic system of an automatic transmission. Normal close solenoid valves and a normal open solenoid valve are used by the system to form the combinationlogic together, under the normal electric control gear shift condition, the solenoid valves are controlled to be on and off through the gear shift logic, and clutch oil cylinders corresponding to thenormal close solenoid valves and the normal open solenoid valve are subjected to oil filling or oil drainage. Under the condition that an electric control system or the solenoid valves are abnormal,corresponding control oil ways achieve oil drainage through the normal close solenoid valves, and oil supply of the corresponding clutch oil cylinder is achieved through the normal open solenoid valve. Shuttle valves are used for isolating solenoid valve control ways under the normal condition and an emergency oil way under the emergency condition and executing the OR logic, any one in the solenoid valve control ways under the normal condition and the emergency oil way under the emergency condition is filled with oil, and the corresponding clutch oil cylinder is filled with oil. According to the system, under the special condition that the electric control system or the solenoid valves of the automatic transmission fail, the state of the hydraulic system is manually switched, and a forwardgear, a neutral gear and a reverse gear are selected so as to achieve the gear shift running function.
