The invention relates to a vehicle range extending power system, a control method and a vehicle, relates to the technical field of vehicle power systems, and aims to solve the technical problem of low efficiency of a gas engine in related technologies. The vehicle range extending power system comprises a generator, a gas engine, a fuel supply device and a controller. And the controller is electrically connected with the gas engine and the electric control pressure regulating valve. The controller is configured to acquire a pressure value within the fuel supply. And under the condition that the pressure value meets the preset operation condition, whether the gas engine is started or not is determined. And under the condition that it is determined that the gas engine needs to be started, the target required torque is obtained. And according to the target demand torque, the gas flow of the fuel supply device is controlled. According to the vehicle range extending power system, the gas supply precision can be improved, so that the working state of the gas engine is accurately controlled, the combustion efficiency is improved, and the efficiency of the gas engine is improved.
