Control method and device for dual-fuel vehicle

The invention discloses a control method and device for a dual-fuel vehicle, and belongs to the field of vehicle electronic control. The control method comprises the following steps that a terminal determines current fuel of an engine in the dual-fuel vehicle through an ECU; according to the current fuel, a control signal corresponding to the current fuel is acquired from the corresponding relation between a fuel identifier and a control signal, and the control signal comprises at least one of the injection amount, the ignition angle and the torque of the current fuel; the self-learning coefficient of the control signal is obtained from storage space of the ECU; and according to the control signal and the self-learning coefficient of the control signal, the engine is controlled to work according to the control signal and the self-learning coefficient of the control signal. According to the control method and device, the terminal can identify the current fuel, so that the control signalcorresponding to the cur
