The invention provides a vehicle acceleration pedal signal intervention control system and method, and belongs to the technical field of vehicle hard line signal processing. A control unit collects an original signal of an accelerator pedal and receives a state request signal from an automatic clutch control unit. By above information to judge control mode, the original signal is processed by a control strategy according to the corresponding control mode and then is virtually output to an engine management system to be used. The vehicle acceleration pedal signal intervention control system and the method have the advantages that a CAN communication function is conducted, can receive the states of an engine and a vehicle, and can receive the state of the automatic clutch; and the engine control logic does not respond to the torque demand of the automatic clutch, by controlling the accelerator pedal, the engine torque demand is achieved, cost is low, the technology is advanced and can be compatible with a plurality of vehicle models, and the industrialization is achieved easily.
