Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0029] Example 1

[0030] Figure 1 This is a flowchart of a vehicle range extender power generation control method provided in Embodiment 1 of the present invention. This embodiment is applicable to controlling the power generation of a vehicle range extender. This method can be executed by a vehicle range extender power generation control device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0031] S101. Obtain road information corresponding to the road where the target vehicle is traveling.

[0032] The target vehicle can refer to a range-extended electric vehicle for which range extender power generation control is to be performed. Road information can refer to road condition information ahead of the road the target vehicle is traveling on. For example, road information may include, but is not limited to, road gradient information and road curvature information.

[0033] For example, the slope and curvature information of the road ahead can be obtained through map navigation using a Tbox (Telematics Box, remote communication terminal).

[0034] S102. Based on the driving database and the road information, determine the expected target power corresponding to the engine of the target vehicle.

[0035] The desired target power can refer to the driving power of the target vehicle at the lowest fuel consumption. The driving database records the target vehicle driving power corresponding to road information.

[0036] Specifically, the determined road information is compared and matched with a driving database to determine the expected target power of the engine of the target vehicle. For example, firstly, it is necessary to collect years of driving data from the CAN bus of the same vehicle model on the vehicle-to-everything (V2X) big data platform. This driving data needs to include at least the current slope and curvature of the road during vehicle operation, as well as the vehicle's speed, fuel consumption, engine speed, actual engine torque, and actual engine power. Using 100-meter intervals, the average value of data within 100 meters is taken as the current point's data to prevent abrupt changes in data values ​​between points. Then, according to the input information (slope, curvature), data with fuel consumption below a certain threshold is labeled as excellent, while data with fuel consumption above a certain value is not labeled. After training using a machine learning algorithm, a corresponding training model is obtained. Subsequently, when the vehicle is actually driving, its current and forward map information (slope, curvature) is collected, and the current fuel consumption is evaluated to determine whether it is excellent. If the current driving data is not excellent, the engine power corresponding to excellent fuel consumption based on the forward map data is given as the expected target power.

[0037] Optionally, the present invention provides another method for determining the desired target power. For example, determining the desired target power corresponding to the engine of the target vehicle based on the driving database and the road information includes: matching the road information with the driving database to determine an engine power range that matches the road information; and determining the desired target power corresponding to the engine of the target vehicle based on a driving state and power lookup table, according to the current driving state information of the target vehicle and the engine power range.

[0038] It should be noted that the driving database contains engine power ranges corresponding to various types of road information. The road information can be matched with the driving database to determine the engine power range that matches the road information. Based on the relationship between driving status information and power ranges in the driving status and power lookup table, the desired target power corresponding to the current driving status of the target vehicle's engine can be determined.

[0039] For example, determining the desired target power of the target vehicle based on the driving state and power lookup table, according to the current driving state information of the target vehicle and the engine power range, includes: determining the target reference sub-interval corresponding to the engine power range in the driving state and power lookup table; and performing matching processing between the current driving state information and the target reference sub-interval to determine the desired target power corresponding to the current driving state information.

[0040] The driving status and power comparison table includes at least one comparison sub-interval.

[0041] Specifically, based on the current driving status information, a target reference sub-interval corresponding to the engine power range is determined in the driving status and power lookup table. The current driving status information is input into the target reference sub-interval for matching processing to determine the desired target power corresponding to the current driving status information.

[0042] S103. Determine the target power generation power corresponding to the target vehicle range extender based on the desired target power and the road information.

[0043] The target power generation can refer to the optimal power generation corresponding to the target vehicle range extender.

[0044] Optionally, the total power required for the target vehicle to travel on the current road is determined based on road information. Based on the total power and the expected target power corresponding to the engine, the power value required to be provided by the target vehicle's electric motor is determined. Based on the power value required to be provided by the electric motor, the target power generation capacity corresponding to the target vehicle's range extender is determined.

[0045] S104. Based on the forward feedback control strategy, control the target vehicle range extender to generate electricity according to the target power generation.

[0046] Specifically, based on the feedback control strategy, the target vehicle range extender is controlled to generate electricity according to the target power output, so as to achieve closed-loop control of the target vehicle range extender.

[0047] The technical solution of this invention involves acquiring road information corresponding to the road where the target vehicle is traveling; determining the desired target power of the engine of the target vehicle based on a driving database and the road information; determining the target power generation of the range extender of the target vehicle based on the desired target power and the road information; and controlling the range extender of the target vehicle to generate electricity according to the target power generation based on a forward feedback control strategy. This approach enables more intelligent control of the range extender, while simultaneously improving its working efficiency and further optimizing the economics of the range extender vehicle.

[0048] Example 2

[0049] Figure 2 This is a flowchart of a vehicle range extender power generation control method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further refines the determination of the target power generation corresponding to the target vehicle range extender. For example... Figure 2 As shown, the method includes:

[0050] S201. Obtain road information corresponding to the road where the target vehicle is traveling.

[0051] S202. Based on the driving database and the road information, determine the expected target power corresponding to the engine of the target vehicle.

[0052] S203. Based on the universal characteristic curve and the desired target power, determine the desired operating speed of the target vehicle engine.

[0053] Specifically, the operating speed point corresponding to the desired target power is queried through the universal characteristic curve, and this point is determined as the desired operating speed of the target vehicle engine.

[0054] On the other hand, determining the desired operating speed of the target vehicle engine based on the universal characteristic curve and the desired target power may include: matching the desired target power with the universal characteristic curve to determine the desired operating speed that matches the desired target power.

[0055] Specifically, the desired target power is input into a universal characteristic curve comparison tool for matching processing to determine the desired operating speed that matches the desired target power.

[0056] S204. Based on the desired operating speed and the desired target power, determine the target engine torque corresponding to the target vehicle engine.

[0057] The target engine torque can refer to the engine torque based on the desired operating speed and desired target power.

[0058] Specifically, by substituting the desired operating speed and desired target power into the conventional torque calculation formula, the target engine torque corresponding to the target vehicle engine can be calculated.

[0059] S205. Based on the target engine torque and the road information, determine the target power generation corresponding to the target vehicle range extender.

[0060] For example, determining the target power generation corresponding to the target vehicle range extender based on the target engine torque and the road information includes: determining the target vehicle drive torque required for the target vehicle to travel on the current road; determining the torque difference between the target vehicle drive torque and the target generator torque, and determining the torque difference as the target motor torque; determining the target power consumption corresponding to the target vehicle motor based on the target motor torque and the motor speed; and determining the target power generation corresponding to the target vehicle range extender based on the target power consumption.

[0061] The target torque can refer to the total torque required for the target vehicle to travel on the current road.

[0062] Specifically, based on the road information corresponding to the currently traveled road, the target vehicle drive torque required for the target vehicle to travel on the current road is determined. The torque difference between the target vehicle drive torque and the target generator torque is determined. This torque difference is then determined as the target motor torque required by the target vehicle's electric motor. Based on the target motor torque and motor speed, the target power consumption corresponding to the target vehicle's electric motor is calculated. Based on the target power consumption and losses, the target power generation corresponding to the target vehicle's range extender can be determined.

[0063] For example, the target power consumption corresponding to the target vehicle motor is determined in the following manner:

[0064] P = T * N / C

[0065] Where P is the target power consumption, N is the motor speed, T is the target motor torque, and C is a constant. It should be noted that the specific value of the constant C depends on the unit. For example, when the target power consumption is in kW, the constant C is 9550; when the target power consumption is in W, the constant C is 9.55.

[0066] S206. Based on the forward feedback control strategy, control the target vehicle range extender to generate electricity according to the target power output.

[0067] The technical solution of this invention determines the desired operating speed of the target vehicle engine based on the universal characteristic curve and the desired target power; determines the target engine torque of the target vehicle engine based on the desired operating speed and the desired target power; and determines the target power generation of the target vehicle range extender based on the target engine torque and the road information. This allows for intelligent determination of the power generation of the new energy vehicle range extender, intelligent allocation of the range extender's operating strategy, and further improvement of the economic performance of the range extender vehicle.

[0073] The range extender control module 304 is used to control the target vehicle range extender to generate electricity according to the target power output based on a forward feedback control strategy.
