For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0030] Figure 1 The flowchart of the first embodiment of a control method of a range extender provided by the present application is shown, and the method is executed by a vehicle. Figure 1 As shown, the method comprises the following steps:

[0031] Step S110: If the downtime of the range extender exceeds a first preset time, obtaining the current vehicle speed;

[0032] Among them, the downtime duration of the range extender can be calculated by obtaining the difference between the current year, month and day and the year, month and day when the range extender was last shut down. The first preset duration can be 20 days, 30 days, etc., and the number of days in the first preset duration can be set according to actual conditions.

[0033] Step S120: starting the range extender according to the current vehicle speed.

[0034] Among them, at different vehicle speeds, the start-up method of the range extender is different. By obtaining the current vehicle speed, the start-up of the range extender is controlled according to the current vehicle speed, thereby achieving periodic start-up of the range extender to prevent the range extender from not starting for a long time, causing difficulty in starting the engine.

[0035] By obtaining the downtime of the range extender, if the downtime of the range extender exceeds a first preset time, the current vehicle speed is obtained, and the start of the range extender is controlled according to the current vehicle speed, so as to achieve periodic start of the range extender to prevent the engine from starting difficulty due to the long-term non-start of the range extender; if the engine has not been started for a long time, the lubricity of the engine oil may decrease after being left stationary for a long time, especially if the engine oil is close to the replacement cycle or the quality is poor, it may accelerate oxidation and deterioration, and lose effective protection for engine components. By periodically starting the range extender, the engine oil lubricates the engine components, thereby protecting the engine components. ; If the engine has not been started for a long time, the lubricating oil film on the crankshaft bearings, connecting rod bearings and other parts may be lost due to gravity, causing dry friction at the moment of starting, increasing the risk of wear. By periodically starting the range extender, the lubricating oil can lubricate the crankshaft bearings and connecting rod bearings and other parts to prevent dry friction between the crankshaft bearings and connecting rod bearings and other parts, thereby reducing the risk of wear. If the engine has not been started for a long time, incompletely burned substances remaining in the combustion chamber may form carbon deposits, affecting combustion efficiency and emission performance. By periodically starting the range extender, incompletely burned substances in the combustion chamber can be prevented from accumulating in the combustion chamber to form carbon deposits, thereby improving combustion efficiency and emission performance.

[0036] Figure 2 The flowchart of the second embodiment of the range extender control method provided by the present application is shown, and the method is executed by the vehicle. Figure 2 As shown, the start-up of the range extender is controlled according to the current vehicle speed, comprising the following steps:

[0037] Step S210: determining whether the current vehicle speed exceeds a preset vehicle speed threshold;

[0038] Among them, the start-up method of the range extender is different at different vehicle speeds. The start-up method of the controller range extender is determined by determining whether the current vehicle speed exceeds the preset vehicle speed threshold; the preset vehicle speed threshold can be set to 40km / h. The preset vehicle speed threshold can be set according to actual conditions, and the specific setting size is not limited here.

[0039] Step S221: if the current vehicle speed is less than or equal to a preset vehicle speed threshold, obtaining the current power value of the power battery;

[0040] Among them, if the current vehicle speed is less than or equal to the preset vehicle speed threshold, directly starting the range extender will charge the power battery. If the power battery has a high power level, starting the range extender will overcharge the power battery. The current power value of the power battery is obtained to determine whether starting the range extender will cause overcharging.

[0041] Step S231: If the power value of the power battery is less than a preset power threshold, the range extender is controlled to start.

[0042] Among them, if the power value of the power battery is less than the preset power threshold, it means that the power battery is not in a fully charged state, and the range extender can be started directly to prevent the range extender from being difficult to start due to long-term non-startup. The preset power threshold can be set to 80% of the total power of the power battery, and the specific value can be set according to the power generation capacity of each vehicle.

[0043] Step S222: If the current vehicle speed is greater than a preset vehicle speed threshold, the range extender is controlled to start.

[0044] Among them, if the range extender is controlled to start when the current vehicle speed is greater than the preset vehicle speed threshold, the vehicle speed rises to the preset vehicle speed threshold at this time, and the power battery is definitely not fully charged. After the range extender is started, power generation will not cause overcharging of the power battery. The range extender can be directly controlled to start to prevent the range extender from not starting for a long time, which causes difficulty in starting the range extender; and when the vehicle speed is greater than the preset vehicle speed threshold, the NVH (Noise, Vibration, Harshness) generated by the range extender will be less perceived by the user, giving the user a better experience. It should be noted that the selection of starting at a speed greater than the preset vehicle speed threshold or starting at a speed less than the preset vehicle speed threshold can set a selection prompt for the user to choose which start method.

[0045] Figure 3 The flowchart of the third embodiment of a control method of a range extender provided by the present application is shown, and the method is executed by a vehicle. Figure 3 As shown, after the range extender is started according to the current vehicle speed control, the following steps are further included:

[0046] Step S310: determining the operating time of the range extender;

[0047] After the range extender is started, the running time of the range extender is obtained to determine whether the lubricating oil in the range extender lubricates the inside of the engine and whether the target lubrication effect is achieved;

[0048] Step S321: if the operating time of the range extender is greater than a second preset time, obtaining the engine water temperature;

[0049] If the operating time of the range extender is greater than the second preset time, the engine water temperature is obtained again to further determine whether the lubricating oil in the engine sufficiently lubricates the interior of the engine.

[0050] It should be noted that the running time can be set to 180S, but the specific length is not limited here and can be set according to the actual engine type.

[0051] Step S322: If the operating time of the range extender is less than the second preset time, maintaining the range extender in the operating state;

[0052] Step S332: If the operating time of the range extender reaches the preset second preset time, the engine water temperature is obtained.

[0053] Among them, if the running time of the range extender is less than the second preset time, it means that the lubricating oil in the engine has not yet fully lubricated the inside of the engine, and the range extender is controlled to continue running until the range extender runs to the second running time, and then the water temperature is judged whether it meets the preset water temperature threshold. Even under high temperature conditions, the engine water temperature exceeds the preset water temperature threshold within the second preset time. By determining that the running time of the range extender is greater than the second preset time, the range extender will be controlled to shut down, which can ensure that the lubricating oil in the engine has fully lubricated the inside of the engine.

[0054] Step S331: determining whether the engine water temperature is greater than a preset water temperature threshold;

[0055] Among them, under severe cold conditions, even if the range extender runs for longer than the second preset time, since the engine water temperature does not reach the preset water temperature threshold, after the range extender runs for longer than the second preset time, it is determined whether the engine water temperature is greater than the preset water temperature threshold, and further determines whether the lubricating oil in the engine is sufficient to lubricate the engine. It should be noted that the range extender includes an engine and a generator, and the engine water temperature can be set to 70°C, but the specific temperature of the engine water temperature is not limited here and can be set according to actual conditions.

[0056] Step S341: If the engine water temperature is greater than the preset water temperature threshold, the range extender is controlled to shut down.

[0057] Among them, if the engine water temperature is greater than the preset water temperature threshold, it means that the lubricating oil in the engine has fully lubricated the inside of the engine, and the range extender is controlled to shut down to reduce the fuel consumption of the range extender. Compared with directly using the power of the power battery pack to drive the vehicle, it has better economy and NVH.

[0058] Step S342: If the engine water temperature is less than or equal to the preset water temperature threshold, the range extender is maintained in operation until the engine water temperature is greater than the preset water temperature threshold, and the range extender is controlled to shut down.

[0059] Among them, if the engine water temperature is less than or equal to the preset water temperature threshold, it means that sufficient combustion has not occurred in the engine and the lubricating oil in the engine has not reached the target lubrication state. The range extender is controlled to be in an operating state until the engine water temperature rises to a value greater than the preset water temperature threshold, that is, the lubricating oil in the engine has fully lubricated the engine, and then the range extender is controlled to shut down.

[0060] In another embodiment of the present application, after controlling the range extender to start according to the current vehicle speed, the method further includes: controlling the range extender to generate electricity according to a preset power generation power.

[0061] In this embodiment, the power generation power can be set to the minimum power generation power by controlling the range extender to generate power according to the preset power generation power. For example, the power generation power is set to 5kw. On the one hand, the range extender generates power according to the minimum power generation power, and the NVH generated is small, which is not easy for passengers to perceive, giving users a better experience. On the other hand, the range extender requires less fuel consumption to generate power according to the minimum power generation power, and uses more of the power of the power battery pack to drive the drive motor, which has good economy.
