Vehicle control method and device, storage medium and hybrid vehicle

Abstract

The invention relates to a vehicle control method and device, a storage medium and a hybrid vehicle. The method comprises the steps that if a high-voltage interlocking fault is detected, whether a high-voltage contactor is in a closed state or not is detected, and when an engine does not work, the engine is controlled to be started; if the high-voltage contactor is in the closed state, whether the high-voltage contactor is disconnected or not is judged at least according to the current running state of the hybrid power vehicle, and the current running state is one of the starting state and the running state; and if the high-voltage contactor is determined to be disconnected, controlling the high-voltage contactor to be disconnected. Therefore, the probability of vehicle power failure caused by a high-voltage interlocking fault can be reduced, and traffic accidents and traffic jams caused by sudden power failure and parking can be reduced. In addition, when the vehicle has the high-voltage interlocking fault, if the engine does not work, the engine is controlled to be started. Therefore, when the vehicle is powered off, the vehicle can still be driven by the engine to run, so that the basic running function of the vehicle is ensured, and the public traffic safety is prevented from being influenced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a vehicle control method, device, storage medium, and hybrid vehicle. Background technique [0002] The high-voltage interlock function of a hybrid vehicle can be used to detect the integrity of its high-voltage system. When the vehicle interlock circuit is disconnected, the vehicle will detect a high-voltage interlock fault. When a high-voltage interlock fault occurs in the vehicle, if the high voltage is connected (that is, the high-voltage contactor is in a closed state), the high-voltage contactor is directly disconnected, or a fault prompt is given when the vehicle is running at high speed, and the high-voltage contactor is disconnected when the vehicle is running at a low speed . When the engine is not working: If the high-voltage contactor is directly disconnected, the vehicle may stop due to a sudden power failure and cause a traffic accident; if the vehic...

Problems solved by technology

When the engine is not working: If the high-voltage contactor is directly disconnected, the vehicle may stop due to a sudden power failure and cause a traffic accident; if the vehicle is running at an intersection or at a traffic light at a low speed, a sudden power failure may cause traffic jams
