The invention provides a single-motor hybrid vehicle engine torque control strategy and system, and belongs to the technical field of hybrid vehicles. The problems that in the prior art, after the required torque is increased to be larger than the target torque of an engine in the last control period, fuel consumption of a power assembly is large, and fuel economy is low are solved. The single-motor hybrid vehicle engine torque control strategy comprises the following steps: A, setting a control mode; b, activating the control mode; c, obtaining a current target torque; d, calculating motor torque. The single-motor hybrid vehicle engine torque control system comprises a vehicle control unit, the vehicle control unit is connected with an engine controller used for sending the state of an engine and the actual torque of the engine, and the vehicle control unit is further connected with a motor controller, a gearbox controller, an accelerator opening degree sensor and a vehicle speed sensor. The fuel economy of the power assembly is high while the required torque response speed of the vehicle can be guaranteed.
