Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to the field of vehicle energy-saving technology, specifically to a vehicle energy-saving method, device, storage medium, and vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, the use of range-extended electric vehicles (REEVs) is becoming increasingly widespread. REEVs use a range extender to generate electricity to replenish the battery, increasing the driving range and alleviating range anxiety to some extent.

[0003] However, even if the generator and motor parameters are identical, the range extender's capability in existing range-extended electric vehicles is still limited by the engine's external characteristics. Furthermore, the range extender cannot automatically determine whether to activate energy-saving mode based on various vehicle operating parameters, leading to excessive energy consumption and increased operating costs. Summary of the Invention

[0004] This application provides a vehicle energy-saving method, device, storage medium, and vehicle to at least solve the problem of excessive energy consumption in range-extended electric vehicles in related technologies. The technical solution of this application is as follows: According to a first aspect of this application, a vehicle energy-saving method is provided, the method comprising: after the vehicle activates an energy-saving mode, acquiring the cumulative output power of the vehicle's range extender and the total vehicle power consumption during a first time period; the first time period being any time period after the vehicle enters the energy-saving mode; determining a target operating state of the range extender in a second time period based on the cumulative output power and the total vehicle power consumption; the second time period being after the first time period, the target operating state including an on state or an off state; and controlling the range extender to operate in the target operating state.

[0005] Based on the above technical means, real-time monitoring of the cumulative output power of the range extender and the total vehicle power consumption in the first period is realized when the vehicle is running in energy-saving mode. Based on the cumulative output power and the total vehicle power consumption, the target operating state of the range extender is determined, so that the range extender can flexibly switch operating modes to keep the vehicle running in a low-energy state and achieve the purpose of energy saving.

[0006] In one possible implementation, the target operating state of the range extender in the second time period is determined based on the cumulative output power and the vehicle power consumption, including: if the difference between the cumulative output power and the vehicle power consumption is greater than or equal to a preset difference threshold, the target operating state of the range extender in the second time period is determined to be the off state; if the difference between the cumulative output power and the vehicle power consumption is less than the preset difference threshold, the target operating state of the range extender in the second time period is determined to be the on state.

[0007] Based on the above technical means, the target operating state of the range extender is subject to conditional restrictions, so that the range extender stops operating when the difference between the cumulative output power and the vehicle power consumption is greater than or equal to a preset difference threshold; and continues to operate when the difference between the cumulative output power and the vehicle power consumption is less than the preset difference threshold, thereby achieving the purpose of energy saving.

[0008] In one possible implementation, before acquiring the total vehicle power consumption and the cumulative output power of the range extender during the first time period when the vehicle is in energy-saving mode, the method further includes: acquiring the vehicle's operating parameters and a first operation; the operating parameters include the vehicle's operating status and the vehicle's battery charge; and controlling the vehicle to activate the energy-saving mode when the vehicle's operating parameters meet a first preset condition and the first operation is used to indicate activating the energy-saving mode.

[0011] Based on the aforementioned technical means, specific restrictions have been placed on the conditions for the vehicle to operate in energy-saving mode. When the vehicle's operating parameters and activation information both meet the preset activation conditions, the energy-saving mode is allowed to operate, making the way to enter energy-saving mode safer.

[0012] In one possible implementation, the method further includes: acquiring vehicle operating parameters or a second operation; the vehicle operating parameters include the vehicle's operating state and the vehicle battery's charge level; when the vehicle's operating parameters meet a second preset condition, or when the second operation is used to indicate the shutdown of the energy-saving mode, controlling the vehicle to shut down the energy-saving mode; the second preset condition includes at least one of the following: the vehicle's operating state is a power-off operating state, the vehicle's operating state is a fault operating state, and the vehicle battery's charge level is less than or equal to a second preset charge level threshold.

[0013] Based on the aforementioned technical means, specific restrictions have been placed on the conditions for turning off the energy-saving mode of a vehicle. When the vehicle's operating parameters and activation / deactivation information both meet the preset conditions for turning off the energy-saving mode, the energy-saving mode can be turned off, making the method of turning off the energy-saving mode safer.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0030] For ease of understanding, the vehicle energy-saving method provided in this application will be described in detail below with reference to the accompanying drawings.

[0031] Figure 1 This is a schematic flowchart illustrating a vehicle energy-saving method according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps: S101. After the vehicle activates the energy-saving mode, obtain the cumulative output power of the vehicle's range extender and the total vehicle power consumption during the first time period.

[0032] It should be noted that this application uses range-extended electric vehicles as an example to specifically illustrate the implementation of the energy-saving mode. The embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0033] Figure 2This is a schematic diagram illustrating the connection relationship of an internal vehicle system according to an exemplary embodiment. For example... Figure 2 As shown, the vehicle internal system provided in this application includes a range extender, an engine, a generator, and a speed ratio connection mechanism (…). Figure 2 (not shown in the image) and electronic control unit (ECU).

[0034] Among them, the belt speed ratio connection mechanism matches a certain speed ratio according to the characteristics of the engine and generator, so that the high efficiency range of the engine and generator overlaps, thereby improving the oil-electric conversion efficiency of the range extender system.

[0035] like Figure 2 As shown, the engine, generator, and range extender are mechanically connected and communicate with the ECU. In addition, the ECU also communicates with other vehicle control systems to cooperate with each other, ultimately controlling the range extender to operate at a fixed high-efficiency operating point, reducing the dynamic changes of the range extender's operating conditions, minimizing fuel consumption, and achieving ultimate energy saving.

[0036] Other control systems for the vehicle mainly include the drive system and battery system, which primarily monitor relevant parameters for logical mode determination.

[0037] In some embodiments, when the range extender operates at its high-efficiency operating point, the output power of the range extender can essentially cover the power consumption of the entire vehicle.

[0038] In some embodiments, the operating point with the lowest fuel consumption (i.e., the high-efficiency operating point) can be obtained based on the universal characteristics of the selected engine and the generator efficiency. If the output power of the range extender cannot cover the total vehicle power consumption at the operating point with the lowest fuel consumption, the operating points with lower fuel consumption can be classified according to the power output, but in principle, no more than three levels.

[0039] In specific implementation, when the vehicle is cruising at a constant speed of 100 km / h, the power consumption is about 20 kW. This application takes a vehicle speed of less than 100 km / h (i.e., a speed ≤ 100 km / h) as the common speed of the vehicle as an example to specifically illustrate the implementation method of the energy-saving mode.

[0040] In some embodiments, when the vehicle is in motion but not in energy-saving mode, the range extender is in the default working state, that is, the off state or other working state. At this time, it can be determined whether the vehicle can run in energy-saving mode based on the vehicle's operating parameters and activation operation information.

[0041] Figure 3This is a schematic flowchart illustrating another vehicle energy-saving method according to an exemplary embodiment, used to determine whether the vehicle can operate in energy-saving mode when the vehicle is in motion but not in energy-saving mode. Figure 3 As shown, the method includes the following steps: S11. Obtain the vehicle's operating parameters and perform the first operation.

[0042] The vehicle's operating parameters include its operating status and battery charge. Operating status includes high-voltage operation, power-off operation, and fault operation.

[0043] Specifically, when the vehicle is in high-voltage operation mode, all high-voltage components and systems within the vehicle operate normally, and the vehicle can be driven safely. When the vehicle is in power-off operation mode, the vehicle is powered off, and all components and systems within the vehicle are in a dormant state, preventing the vehicle from moving. When the vehicle is in fault operation mode, components or systems within the vehicle may malfunction, and the vehicle cannot be driven safely.

[0044] In some embodiments, when the vehicle is in motion but not in energy-saving mode, it can be determined whether the vehicle can operate in energy-saving mode by acquiring the vehicle's operating parameters and a first operation.

[0045] S12. When the vehicle's operating parameters meet the first preset conditions and the first operation is used to indicate the activation of the energy-saving mode, control the vehicle to activate the energy-saving mode.

[0046] In some embodiments, the first preset conditions include the vehicle operating in a high-voltage operating state and the battery level being less than or equal to a first preset battery level threshold.

[0047] It should be noted that the first preset battery threshold is preset and stored in the memory by the vehicle manufacturer. Different vehicle manufacturers may set different first preset battery thresholds, and this application does not limit this.

[0048] Optionally, the first preset power threshold can be... .

[0049] For example, when the vehicle is operating in a high-voltage state and the vehicle battery charge is less than or equal to... Furthermore, when the driver's first operation is to indicate that the energy-saving mode is to be activated, the vehicle is controlled to operate in the energy-saving mode.

[0050] In some embodiments, when the vehicle is operating in energy-saving mode, the range extender operates at a preset power.

[0051] It should be noted that the preset power is preset and stored in the memory by the vehicle manufacturer. Different vehicle manufacturers may set different preset power, and this application does not limit this.

[0054] In some embodiments, when the vehicle is operating in energy-saving mode, the ECU monitors and calculates the cumulative output power of the range extender and the total vehicle power consumption during the first period in real time.

[0055] For example, when the vehicle is running in energy-saving mode, if the range extender has an operating power of 20KW and the corresponding engine speed is 2000rpm, then the engine specific fuel consumption at this operating point is 230g / KWH.

[0056] It should be noted that if different levels of fixed operating points are set in energy-saving mode, the vehicle's power consumption in the first time period should be monitored in real time, and the corresponding level of operating point should be selected according to the vehicle's power consumption.

[0057] The first time period refers to any time period after the vehicle enters energy-saving mode.

[0058] Optional, Figure 4 This is a schematic diagram of the operating phase of a range extender according to an exemplary embodiment, such as... Figure 4 As shown, The moment when the range extender starts operating. This is the moment when the range extender ends operation. The first time period can be a time interval (...). , ).

[0060] For example, when the vehicle is operating in energy-saving mode, the cumulative output power of the range extender is... (Right now Figure 4 Medium shaded area), first time period ( , Within ) the vehicle's total power consumption is .

[0061] Optionally, the cumulative output power is The calculation method is shown in formula (1): = Formula (1) in, This represents the cumulative duration of the first time period, expressed in hours (h). The calculation method is shown in formula (2): =( - ) / 3600 formula (2) S102. Determine the target operating state of the range extender in the second time period based on the cumulative output power and the total power consumption of the vehicle.

[0062] The second time period follows the first time period, and the target operating status includes the on state and the off state.

[0063] In some embodiments, when the vehicle's cumulative output power and total vehicle power consumption are obtained, the target operating state of the range extender in the second time period can be determined based on the cumulative output power and total vehicle power consumption.

[0064] Figure 5 This is a schematic flowchart illustrating another vehicle energy-saving method according to an exemplary embodiment, used to determine the target operating state of the range extender in a second time period. Figure 5 As shown, the method includes the following steps: S1021. If the difference between the cumulative output power and the vehicle power consumption is greater than or equal to a preset difference threshold, the target operating state of the range extender in the second time period is determined to be the off state.

[0065] It should be noted that the preset difference threshold is preset and stored in the memory by the vehicle manufacturer. Different vehicle manufacturers may set different preset difference thresholds, and this application does not limit this.

[0066] Optionally, the preset difference threshold can be... .

[0067] For example, when the cumulative output power With the total power consumption of the vehicle The difference between Greater than or equal to the preset difference threshold ,Right now ≥ At that time, the target operating state of the range extender in the second time period is determined to be the off state.

[0068] S1022. If the difference between the cumulative output power and the vehicle power consumption is less than the preset difference threshold, the target operating state of the range extender in the second time period is determined to be the on state.

[0069] For example, when the cumulative output power With the total power consumption of the vehicle The difference between Less than the preset difference threshold ,Right now < At that time, the target operating state of the range extender in the second time period is determined to be the on state.

[0070] S103, Control the range extender to operate in the target operating state.

[0071] In some embodiments, when it is determined that the target operating state of the range extender in the second time period is off, the range extender is controlled to stop working.

[0072] It should be noted that when the range extender stops working, the vehicle runs in pure electric mode.

[0073] In some embodiments, when it is determined that the target operating state of the range extender in the second time period is the on state, the range extender is controlled to continue operating.

[0074] Based on the aforementioned technical means, intelligent restrictions can be placed on the conditions for vehicles to enter the showroom mode, avoiding the risk of accidental activation during daily use and preventing unnecessary impacts. It also prevents safety issues arising from occupants activating the showroom mode without the permission of the vehicle's manager, thereby enhancing the product experience for exhibitors.

[0075] In some embodiments, when the vehicle is operating in energy-saving mode, it can be determined whether to exit energy-saving mode by the vehicle's operating parameters or a second operation.

[0078] It should be noted that the explanation of the vehicle's operating parameters is as described in step S11 above, and will not be repeated here.

[0079] S105. When the vehicle's operating parameters meet the second preset conditions, or when the second operation is used to indicate that the energy-saving mode should be turned off, control the vehicle to turn off the energy-saving mode.

[0080] The second preset condition includes at least one of the following: the vehicle is in a power-off state, the vehicle is in a fault state, or the vehicle battery charge is less than or equal to the second preset charge threshold.

[0081] It should be noted that the second preset battery threshold is preset and stored in the memory by the vehicle manufacturer. Different vehicle manufacturers may set different second preset battery thresholds, and this application does not limit this.

[0082] Optionally, the second preset power threshold can be... .

[0083] For example, when the vehicle is in a power-off operating state, the energy-saving mode is turned off.

[0084] Alternatively, when the vehicle is in a faulty operating state, control the vehicle to turn off the energy-saving mode.

[0085] Or, when the vehicle battery charge is less than or equal to At that time, control the vehicle to turn off the energy-saving mode.

[0086] Alternatively, the vehicle can be controlled to turn off the energy-saving mode when the driver presses the button to turn off the energy-saving mode.
