The invention relates to a hybrid electric vehicle starting oil injection control system and method capable of giving consideration to emission. The system comprises an EHC heating circuit and a hybrid heating circuit. The EHC heating circuit comprises a bypass valve, an EHC, a TWC, a GPF and DeNOx which are connected in sequence, and the DeNOx is connected with the outside atmosphere; the mixed heating circuit comprises a bypass valve, a DOC, an EHC, a TWC, a GPF and DeNOx which are connected in sequence, and the DeNOx is connected with the outside atmosphere; a temperature sensor T1 is arranged at the EHC inlet, a temperature sensor T2 is arranged at the TWC inlet, and a temperature sensor T3 is arranged at the DeNOx inlet; the system further comprises a hybrid power control unit and a starting control unit. The bypass valve is connected with an engine, and switching of pneumatic working modes is achieved through opening and closing of the bypass valve. Compared with the prior art, the hybrid electric vehicle can reach the optimal starting state in a short time under the low-temperature and feed environment, emission in the engine starting process is effectively reduced, and meanwhile the dynamic property and economical efficiency of the vehicle are considered.
