Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular, to a system for regulating a vehicle's power retention mode, a method for regulating a vehicle's power retention mode, a vehicle applying the regulation system, a computer device for implementing the regulation method, and a computer-readable storage medium for executing the regulation method. Background Art

[0002] A hybrid vehicle (HEV) is a vehicle whose propulsion system consists of two or more separate propulsion systems that can operate simultaneously. The vehicle's driving power is provided by the individual propulsion systems individually or in combination, depending on the actual driving conditions. Hybrid vehicles typically have three driving modes: hybrid, electric, and e-save. In hybrid mode, the powertrain first uses the battery, then adds engine power. Hybrid mode is suitable for a variety of road conditions, but requires higher energy consumption. In electric mode, the powertrain uses the battery for power and only switches to the engine when the battery is low or when greater power is needed. This is suitable for everyday urban commuting, offering a smoother ride and lowering emissions, but is not suitable for long driving range requirements. In e-save mode, the powertrain prioritizes engine power and maintains the battery charge at a certain level, using the engine to recharge the battery, thereby conserving energy for later use. This allows the driver to switch to electric mode when driving in urban or mountainous areas, using the energy saved in e-save mode to extend the vehicle's range.

[0003] Currently, it is often necessary to manually select the battery-sustaining mode while driving. However, in battery-sustaining mode, the engine is required to charge the battery. Therefore, inappropriately enabling battery-sustaining mode may reduce the vehicle's fuel efficiency and increase its energy consumption. Therefore, it is necessary to provide a vehicle battery-sustaining mode adjustment system to adjust the on and off of battery-sustaining mode. Summary of the Invention

[0031] The making and using of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and are not intended to limit the scope of the invention.

[0032] In addition, the flowcharts and block diagrams in the accompanying drawings illustrate possible implementations of the architecture, functionality, and operations of the methods and systems according to various embodiments of the present invention. It should be noted that the functions noted in the blocks may occur in a different order than that noted in the accompanying drawings. For example, two blocks shown in succession may actually be executed substantially in parallel, or they may sometimes be executed in the opposite order, depending on the functions involved.

[0033] The charge-sustaining mode of a hybrid vehicle can maintain the battery charge at a certain level while the vehicle is in motion. During this time, the engine consumes its own fuel to recharge the battery, reserving power for subsequent use. Currently, the charge-sustaining mode is typically enabled and disabled by the driver manually selecting the e-Save button on the vehicle's control panel. The inventors have discovered that if the charge-sustaining mode is enabled when the vehicle's fuel efficiency is low, the engine consumes more fuel, resulting in increased fuel consumption.

[0034] Reference Figure 1 , Figure 1A schematic diagram of a regulating system for a charge-maintaining mode of a vehicle according to an embodiment of the present invention is shown.

[0035] The vehicle charge retention mode adjustment system according to the present invention includes an acquisition module 110, a judgment module 120, and an adjustment module 130. The acquisition module 110 is used to acquire engine parameter information, and the acquisition module 110 includes, for example, an engine control unit (ECU). The judgment module 120 is used to receive the engine parameter information from the acquisition module 110 and determine the engine's thermal efficiency status information based on the engine parameter information. The judgment module 120 is also used to determine whether the determined thermal efficiency status information is within a preset thermal efficiency range. The adjustment module 130 is used to receive the judgment result from the judgment module 120 and activate the charge retention mode if the thermal efficiency status information is within the preset thermal efficiency range, and deactivate the charge retention mode if the thermal efficiency status information is not within the preset thermal efficiency range. Additionally, the preset thermal efficiency range can be a high thermal efficiency range of the engine, for example, 30% to 50%, preferably 30% to 40%.

[0036] Engine thermal efficiency, also known as engine effective efficiency, refers to the ratio of the thermal equivalent of the engine's effective power to the calorific value of the fuel consumed per unit time. Thermal efficiency reflects the economy of the engine as a heat engine, that is, the ratio of the energy generated by fuel combustion to the vehicle's driving force. Therefore, the adjustment system 100 adjusts the power preservation mode on or off by judging the engine's thermal efficiency. When the engine is within a preset thermal efficiency range, that is, when the engine is in a high thermal efficiency state, the power preservation mode is automatically turned on. When the engine is not in a high thermal efficiency state, that is, when the engine's thermal efficiency is low, the power preservation mode is automatically turned off, allowing the engine to charge the battery while consuming less fuel. By intelligently adjusting energy use based on the engine's thermal efficiency, the vehicle can more effectively manage the use of fuel and battery power to maximize overall fuel efficiency. This adjustment method does not require manual operation by the driver, thereby improving the driving experience.

[0037] Reference Figure 2 , Figure 2 A universal characteristic curve of an engine of a vehicle according to one embodiment of the present invention is shown.

[0038] In certain embodiments, the engine parameter information may include real-time engine motion information and universal characteristic curve information. The real-time engine motion information may, for example, include the real-time engine speed and real-time torque. The engine speed and engine torque may be obtained by an engine control unit. Specifically, the engine control unit obtains real-time speed and torque data by connecting to a speed sensor and a torque sensor for respectively measuring the engine speed and torque. Universal characteristic curve (also known as engine characteristic curve) information is a chart describing engine performance. This curve information is typically derived by engine manufacturers through experiments and tests and then published in the engine's technical specifications or technical manuals. Therefore, the universal characteristic curve information can be accessed based on the engine model.

[0039] like Figure 2 As shown in the figure, the horizontal axis of the universal characteristic curve of the engine is the engine speed, and the vertical axis is the engine torque. Figure 2 The universal characteristic curves shown in the figure usually include the fuel consumption rate curve ( Figure 2 The fuel consumption rate reflects how much output energy is converted per gram of fuel, that is, the fuel conversion efficiency, and the engine thermal efficiency is inversely proportional to the fuel consumption rate, that is, the lower the fuel consumption rate, the higher the engine thermal efficiency. Therefore, the low fuel consumption rate range can be obtained through the universal characteristic curve, which is the high thermal efficiency range of the engine. Figure 2 The medium and high thermal efficiency range is approximately within the range of the curve with a fuel consumption rate of 250g / kwh, that is, Figure 2 The gray area in the figure indicates that the engine thermal efficiency is above approximately 30%. By acquiring real-time engine speed and torque, we can determine whether the engine's current thermal efficiency is within the high thermal efficiency range, which is used to adjust the on / off state of charge retention mode.

[0040] In some embodiments, the adjustment module 130 can turn on the power retention mode when the thermal efficiency of the engine remains within the preset thermal efficiency range for a preset time. In some embodiments, the preset time can be in the range of 30s to 120s, for example, 60s or 90s. In this way, it is possible to avoid turning on the power retention mode when the current thermal efficiency of the engine is within the high thermal efficiency range for only, for example, 10s, thereby increasing the fuel consumption rate of the vehicle, preventing the power retention mode from being frequently turned on and off, and also preventing the vehicle's battery from frequently switching between charging and discharging, thereby extending the battery life. It is understandable that the value range of the preset time is not limited to this and can be changed as needed.

[0041] In some embodiments, the acquisition module 110 can also obtain the driver's adjustment needs. The acquisition module 110 includes, for example, the vehicle's infotainment system. The driver can choose to authorize or not authorize the automatic adjustment of the power preservation mode through the infotainment system. When the driver authorizes the automatic adjustment of the power preservation mode, the adjustment system 100 will be enabled to perform the automatic adjustment process. When the driver does not authorize the automatic adjustment of the power preservation mode, the adjustment system 100 will be disabled. At this time, the vehicle's energy management system (EMS) will select whether to drive the vehicle in hybrid mode or pure electric mode based on the vehicle's current battery power, fuel consumption and other data. In this way, more driver control is provided. The driver can choose whether to turn on the automatic adjustment of the power preservation mode according to his or her driving preferences and needs, thereby improving the overall driving experience. The vehicle's energy management system can also record and analyze the driver's adjustment needs so that it can more accurately adapt to the driver's adjustment intentions, thereby helping to improve overall driving efficiency.

[0042] Reference Figure 3 , Figure 3 A relationship diagram between the driving time and speed of a vehicle in an urban road area and a suburban road area according to an embodiment of the present invention is shown.

[0043] In the following, the European New Car Emissions Test Cycle (NEDC) will be taken as an example to illustrate the adjustment process of the adjustment system of the present invention. The NEDC cycle mainly includes two test conditions, urban conditions and suburban conditions. The urban condition mainly simulates the state of urban driving, including frequent starts and stops, sudden acceleration, sudden deceleration, low-speed driving, etc. The suburban condition simulates the state of driving in the surrounding areas of the city, including operations such as cruise control and braking. When the vehicle is driving in an urban road area, the vehicle does not need to have a high cruising range. At this time, the speed of the vehicle changes frequently. The vehicle can be driven in pure electric mode, and the driver will disable the adjustment system 100, that is, the automatic adjustment of the power maintenance mode is not granted. When the vehicle is traveling in a suburban road area, the vehicle's speed changes are relatively stable, mainly in the uniform acceleration and cruise control stages. The driver can activate the adjustment system 100. The acquisition module 110 of the adjustment system 100 will obtain the current speed and torque of the vehicle engine and the engine's universal characteristic curve information. The judgment module 120 will determine the thermal efficiency status information based on the engine's speed and torque, and judge whether the thermal efficiency status information is within the preset thermal efficiency range of the universal characteristic curve. If the thermal efficiency status information is within the preset thermal efficiency range, the adjustment module 130 will start the power maintenance mode. Figure 3For example, the speed of the vehicle is constant during line segments A-A1, B-B1, and C-C1. At this time, the vehicle is in the cruise control stage. During cruise control, the engine operates in a relatively stable working condition and does not need to frequently adjust the output power or speed, which helps to improve combustion efficiency and mechanical efficiency. Based on the engine parameter information, it is determined whether the current thermal efficiency of the engine is within the preset thermal efficiency range, that is, within the high thermal efficiency range. Then, it is determined whether the duration of the thermal efficiency of the engine within the high thermal efficiency range reaches a preset time. When the preset time is reached, the adjustment system 100 will turn on the power maintenance mode. In this way, the adjustment system 100 can turn on the power maintenance mode according to the driver's adjustment needs and when the thermal efficiency of the engine is within the high thermal efficiency range, so that the vehicle's energy use can be managed more accurately, which helps to maximize driving efficiency.

[0044] In addition, the judgment module 120 may also determine multiple driving states of the vehicle in response to whether the thermal efficiency state information is within a preset thermal efficiency range within a preset time. In some embodiments, the multiple driving states may be, for example, an urban road driving state and a suburban road driving state. The adjustment module 130 may adjust the on and off of the power preservation mode based on the driving state determined by the judgment module 120. For example, the adjustment module 130 may maintain the power preservation mode off in the urban road driving state and maintain the power preservation mode on in the suburban road driving state, so as to more efficiently charge the battery in the power preservation mode. The power preservation mode may be automatically turned on or off according to the driving state, thereby providing a more seamless and intelligent driving experience, allowing the vehicle to intelligently select the energy usage mode that best suits the current driving environment.
