[0003] At present, the engine control of extended-range vehicles and traditional vehicles is very different. Among them, the engine control of extended-range vehicles is controlled by the VCU (Vehicle Control Unit, vehicle controller) strategy, and there is little human intervention, and even the engine cannot be directly controlled. , the situation that the engine cannot be started when you want to start the engine is not conducive to the maintenance of the car range extender

The invention discloses an electric vehicle and a method and a system for maintenance control of a range extender in the electric vehicle. The method includes steps: acquiring an engine compartment cover state and a current gear position of the electric vehicle, and acquiring accelerator pedal information and brake pedal information of the electric vehicle; when an engine compartment cover of the electric vehicle is in an open state and the electric vehicle is in a neutral gear position currently, judging whether the range extender enters a maintenance control mode or not according to the accelerator pedal information and brake pedal information of the electric vehicle; if the range extender enters the maintenance control mode, controlling an engine and a power generator in the range extender to start the engine, and controlling the engine to operate under different conditions, so that detection and maintenance of the range extender are realized. The electric vehicle and the method and the system for maintenance control of the range extender in the electric vehicle have advantages that difficulty in maintenance of the range extender is effectively lowered, possibility that the range extender enters the maintenance control mode due to misoperation of a user can be lowered, and safety of the vehicle is guaranteed beneficially.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a maintenance control method for a range extender in an electric vehicle, a maintenance control system for a range extender in an electric vehicle, and an electric vehicle. Background technique [0002] In the existing range-extended vehicles, the control technology of the range extender focuses more on the start-stop and working condition control of the vehicle during normal operation, and does not consider how the maintenance personnel operate the engine during later engine maintenance. [0003] At present, the engine control of extended-range vehicles and traditional vehicles is very different. Among them, the engine control of extended-range vehicles is controlled by the VCU (Vehicle Control Unit, vehicle controller) strategy, and there is little human intervention, and even the engine cannot be directly controlled. , When you want to start the engine, you can’t sta...
