The invention provides a cruise control method and device for a hybrid vehicle. The hybrid vehicle comprises a driving motor and an engine. The method comprises the following steps of acquiring driving state information and residual electric quantity of the hybrid vehicle; calculating a target acceleration of the hybrid vehicle according to the driving state information; when the residual electricquantity is greater than a preset threshold value and the target acceleration is a positive value, calculating a target torque of the hybrid vehicle according to the target acceleration; and comparing the target torque with a preset torque value, selecting at least one of the driving motor and the engine as driving equipment according to the comparison result, and driving the hybrid vehicle according to the driving equipment. According to the method, system control of self-adaptive cruise can be realized based on the driving mode and the residual electric quantity of the hybrid vehicle, and the fuel economy of the hybrid vehicle is improved.
