The invention discloses a hybrid electric vehicle and a control method and system thereof. The hybrid electric vehicle comprises an engine, a power motor, a power battery and a DC-DC converter, and anauxiliary motor connected with the engine. The control method comprises the following steps that when the engine and the power motor are both in a fault state, whether the hybrid electric vehicle receives a maintenance failure mode instruction or not is judged; and if the maintenance failure mode instruction is received, the hybrid electric vehicle is controlled to enter a maintenance failure control mode when the auxiliary motor does not break down, so that the hybrid electric vehicle is independently driven to operate through the auxiliary motor. According to the embodiment of the invention, the probability that a trailer must be called when the engine and the power motor fail at the same time and the hybrid electric vehicle cannot be driven can be effectively reduced, meanwhile, when the vehicle cannot be normally driven, a solution capable of driving the vehicle to the nearest maintenance shop for maintenance is provided for a user, many troubles are saved for the user, and the user experience is improved.
Description
Technical field [0001] The present invention relates to the technical field of automobiles, in particular to a control method of a hybrid electric vehicle, a non-temporary computer-readable storage medium, a control system of a hybrid electric vehicle and a hybrid electric vehicle. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. Hybrid electric vehicles, as one of the new energy vehicles, are driven by engines and / or electric motors. [0003] However, in related technologies, when the engine and power motor of the hybrid electric vehicle fail to drive at the same time, the tow truck can only be used to tow the hybrid electric vehicle to the nearest repair shop, which is not only costly, low maintenance efficiency, but also easy to be blocked on the road. Traffic affects traffic safety. Summary of the invention [0004] The present invention aims to solve one of the technic...
