Obviously, the drawings described below are only embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] With the continuous advancement of technology, the engine start-stop control of extended-range vehicles will pursue more precision and efficiency, and improve the driving experience and vehicle performance. Among them, the engine start process control strategy is particularly important. The success or failure of the start directly affects the subsequent power generation of the range extender, thereby affecting the endurance of the entire vehicle.

[0047] Range-extended vehicles need to judge whether the range extender is successfully started and can enter the idle or power generation mode based on the status of the engine and generator. In the prior art, judging whether the range extender is successfully started requires judging based on the generator torque. Currently, the range extender uses a variety of engine fuel forms and displacement sizes, the engine status is different, and the torque is not accurate when the generator has a low torque. Using the above method to judge whether the start is successful will result in inaccurate judgment, resulting in the failure of the range extender to start. Therefore, a solution that can more accurately judge whether the range extender is successfully started is urgently needed.

[0048] The range extender control method, device, electronic device, vehicle and storage medium provided in the embodiment of the present invention monitor the high-voltage direct current of the generator controller and the generator speed; and determine that the range extender is started successfully when the high-voltage direct current of the generator controller is negative, the duration of the high-voltage direct current of the generator controller is greater than the preset threshold, and the generator speed is higher than the target speed. Since the current collected by the generator controller is accurate, the engine will generate a large torque to drag the generator after fuel injection and ignition, so that the generator generates a negative current. Combined with the current generator speed as a condition for judging the success of the engine start, the accuracy of judging the success of the engine start can be improved, and the risk of failure to start the range extender can be reduced.

[0049] Exemplary Implementation Environment

[0050] Please refer to Figure 1 , Figure 1 It is a schematic diagram of an implementation environment involved in the present invention.

[0051] like Figure 1 As shown, an embodiment of the present invention relates to an extended-range electric vehicle, which includes a vehicle controller, a range extender, a range extender controller, a generator, a generator controller, an engine, and an engine controller. When the vehicle controller recognizes a request to start the range extender, it enters the range extender start mode, the engine controller controls the engine to generate mechanical energy by burning fuel, and the output shaft of the engine is connected to the generator, which drives the generator to generate electricity through rotational motion. The generator controller can detect the output current in the range extender start mode and send it to the range extender controller.

[0052] Exemplary Methods

[0053] Figure 2 This is a flow chart of a range extender control method provided by an embodiment of the present invention. Figure 2 In an exemplary embodiment, a range extender control method is provided, and the method may include:

[0054] S210: In response to the range extender start instruction, monitor the operating parameters of the generator controller.

[0055] During the range extender startup process, after the engine is started, the engine drives the generator to start running and generate electricity. The operating parameters include the high-voltage DC current of the generator controller and the generator speed.

[0056] S230: If the high-voltage direct current of the generator controller is negative, and the duration of the high-voltage direct current of the generator controller is greater than a preset threshold, and the generator speed is higher than the target speed, it is determined that the range extender is started successfully.

[0057] It should be noted that the preset threshold can be determined according to the type of generator. For example, the duration of the high-voltage DC current of the generator controller can be 0.5 seconds. The vehicle controller can determine that the engine is started successfully, and the range extender exits the start mode and enters the idle or power generation mode.

[0058] The range extender control method provided by the embodiment of the present invention can determine whether the engine is started successfully by detecting the high-voltage DC current of the generator controller, because the engine will generate a large torque to drag the generator after fuel injection and ignition, so that the generator generates a negative current. Since the current signal output by the generator controller is more accurate, the range extender control method provided by the embodiment of the present invention can more accurately determine whether the range extender is started successfully.

[0059] In one embodiment, the method may further include:

[0060] Get the engine idle speed;

[0061] Based on the engine idle speed, a target speed of the generator is determined.

[0062] The engine idle speed can be determined by experiment or simulation, for example, using computer-aided design (CAD) software or dedicated power system simulation software to simulate the engine's operating state at different speeds. A mathematical model of the engine is established, and the performance of the engine under different working conditions is analyzed through simulation. The design parameters of the engine are adjusted according to the simulation results to optimize the idle speed. The target speed is generally a preset multiple of the idle speed, for example: 1.1 to 1.2 times. The target speed of the engine can be determined based on the engine idle speed, and the target speed of the generator can be set to be the same as the target speed of the engine. When the speed of the generator is higher than the target speed, it can be determined that the generator is operating normally and can provide power to the battery or vehicle.

[0063] In one embodiment, before responding to the range extender start instruction, the method further includes:

[0064] Get the current SOC value of the vehicle;

[0065] If the SOC value is lower than the preset SOC value, the range extender is controlled to enter the start mode.

[0066] The preset SOC value is set according to the design requirements of the vehicle manufacturer and actual usage, and is generally between 20% and 30%. The preset SOC value may not be fixed, but may be dynamically adjusted according to factors such as the vehicle's current operating conditions, driving habits, and environmental conditions.

[0067] The range extender is started to effectively extend the vehicle's cruising range. When the vehicle's SOC value is lower than the preset SOC value, the BMS sends instructions to the vehicle controller through the on-board network (such as the CAN bus). The vehicle controller (such as the ECU) receives the request instruction from the BMS. The controller starts the range extender according to the received instruction and controls the range extender to enter the start mode.

[0068] In one embodiment, after obtaining the current SOC value of the vehicle, the method further includes:

[0069] If the SOC value is greater than the preset SOC value, the vehicle operation scenario is obtained;

[0070] When the vehicle's operating scenario is the preset scenario, a range extender start command is sent.

[0071] In actual applications, preset scenarios can include long-range driving scenarios, high-load scenarios, and emergency handling scenarios. When the vehicle's operating mode is in the preset scenario, the range extender can be started. In long-range driving scenarios, the vehicle may not be able to find a charging station in time. The range extender can start to enter the power generation mode when necessary to extend the cruising range. In high-load scenarios, the vehicle is driving under high-load conditions (such as climbing, high-speed driving, etc.), and the battery power is consumed quickly, so the range extender needs to be turned on. For example: When a vehicle is driving on a mountain road, it needs to accelerate and climb frequently. In an emergency handling scenario, the vehicle suddenly encounters a battery failure or a sharp drop in power, and the range extender needs to be started urgently. For example: The vehicle is driving on a highway and suddenly finds that the battery power is rapidly dropping.

[0072] In one embodiment, after determining that the range extender is successfully started, the method further includes:

[0073] If the SOC value is higher than the preset SOC value, the range extender is controlled to enter the idle mode.

[0074] In the range extender start mode, the engine can be operated at a first idle speed to ensure that the generator can quickly start to generate electricity effectively. Once the engine is running stably and the generator starts to generate electricity effectively, the engine can adjust the speed to a second idle speed, which is lower than the first idle speed, to maintain a higher fuel efficiency until the SOC value is higher than the preset SOC value.
