Embodiment Construction
[0036] figure 1 It is a schematic flowchart of a control method for a range-extending vehicle according to an embodiment of the present invention, which is used to respond to the control requirements of the vehicle controller for the range-extender, wherein the range-extender includes an engine and a generator, Control methods may include:
[0037] S100. Power-on step: power on the range extender controller and make it self-test, and power on the engine controller and generator controller after the self-test of the range extender controller is correct;
[0038] S200. Starting step: the range extender controller starts the engine after receiving the start enabling request from the vehicle controller for the range extender;
[0039] S300. Shutdown step: when the vehicle controller issues a no-start enabling request for the range extender, and the vehicle controller has no power request, the engine stops working;
[0040] S400. Power off step: the range extender controller rece...

The invention provides a control method and system used for an extended-range vehicle, and the vehicle. The control method for the extended-range vehicle is used for responding to the control requirement of a whole vehicle controller to a range extender. The range extender comprises an engine and a power generator, the control method comprises the steps of powering on, starting, shutting down, andpowering off; as for the powering on step, an extended-range controller is powered on to make the extended-range controller conduct self-inspect, an engine controller and a power generator controllerare powered on after self-inspect is conducted and no error exists; as for the starting step, after the extended-range controller receives the starting enabling request of the whole vehicle controller to the range extender, the engine is started; as for the shutting down step, the whole vehicle controller issues a non-starting enabling request on the range extender, and when the whole vehicle controller has no power request, the engine stops working; and as for the powering off step, the extended-range controller receives a high voltage power-off instruction so as to cut off the high voltageaccording to the state of the range extender and control the high voltage of the engine controller and the power generator controller to switch into low-voltage power. According to the control methodand system used for the extended-range vehicle, and the vehicle, the problem that in the prior art, an extended-range vehicle only has three working states which cannot make the extended-range vehiclein an optimal working state is solved.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method, a control system and a vehicle for an extended-range vehicle. Background technique [0002] With the promotion of electric vehicles, the mileage of electric vehicles has become the focus of researchers. However, the high cost and short life of batteries have seriously hindered the development of electric vehicles. mileage issue. [0003] The range-extended electric vehicle refers to a pure electric drive electric vehicle equipped with ground charging and on-board power supply functions. Traditional range-extended vehicles usually only have three working states: start, power generation and shutdown, which obviously cannot meet the requirements of the extended-range vehicle. Requirements for good working conditions. Contents of the invention [0004] An object of the present invention is to provide a control method, control system and vehicle for a ran...
