Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle electrical balance, and particularly relates to a range-extended vehicle power generation method, system and device based on a scenario mode. Background Art

[0002] As a type of new energy vehicle with unique advantages, the power generation scenario of a range-extended electric vehicle mainly focuses on the driving process. In this stage, the core objectives of the power generation system are to achieve the lowest energy consumption, the best NVH (noise, vibration, and harshness) performance, and to meet the power requirements of the driver. Specifically, during vehicle driving, the system will continuously detect the current battery level of the vehicle and the power required by the driver. When the battery level is insufficient or the driving power cannot meet the demand, the range-extended system will be activated to charge the battery or directly supply power to the drive motor.

[0003] Currently, range-extended vehicles generally adopt a power following or fixed-speed point power generation strategy during driving. The power following strategy can adjust the power generation power in real time according to the power required by the driver, while the fixed-speed point power generation strategy generates power at a specific engine speed. During power generation, the impact of engine speed on NVH is fully considered. For example, when the vehicle is in a low-speed state, a lower engine speed is adopted to reduce noise and vibration and improve the ride comfort; while in a high-speed situation, a higher engine speed is used to ensure sufficient power supply for power generation. This solution can effectively supplement the battery power for the entire driving journey to ensure the normal driving of the vehicle to a certain extent.

[0004] However, in the entire driving cycle, the existing technology needs to comprehensively balance the impact of NVH and power generation efficiency, and there is an irreconcilable contradiction between the two. As a subjective feeling, NVH has a crucial impact on the driver's driving experience. To reduce NVH, the engine speed and power output often need to be restricted, but this will lead to a decrease in power generation efficiency because the engine often cannot operate in the best efficiency range under low-speed or power following conditions, resulting in a reduction in power generation efficiency.

[0005] Since it is difficult to find a perfect balance between NVH and power generation efficiency, NVH will inevitably have a certain impact on the driver during the entire journey. For example, in some working conditions, increasing the engine speed to ensure power generation efficiency may lead to an increase in vehicle interior noise and vibration, reducing the ride comfort. At the same time, the low power generation efficiency in some working conditions will directly affect the fuel consumption performance. The range extender consumes fuel during power generation. If the power generation efficiency is low, it means that more fuel needs to be consumed to generate the same amount of electricity, increasing the vehicle's usage cost and not conforming to the development trend of energy conservation and emission reduction.

[0006] In summary, the existing power generation control strategies are relatively fixed, lacking a mechanism for dynamic optimization based on real-time road conditions, and unable to adjust the power generation state and effect of the vehicle in a timely and accurate manner.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0036] As a type of new energy vehicle with unique advantages, the power generation scenario of a range-extended electric vehicle mainly focuses on the driving process. In this stage, the power generation system aims to achieve the core goals of minimum energy consumption, the best NVH (Noise, Vibration, and Harshness) performance, and meeting the power demand of the driver. Specifically, during the vehicle driving process, the system will detect the current battery level and the power demand of the driver in real time. When the battery level is insufficient or the driving power cannot meet the demand, the range-extending system will be activated to charge the battery or directly supply power to the drive motor.

[0037] Currently, range-extended vehicles generally adopt a power-following or constant-speed-point power generation strategy during the driving process. The power-following strategy can adjust the power generation power in real time according to the driver's demand power, while the constant-speed-point power generation strategy generates power at a specific engine speed. During the power generation process, the impact of engine speed on NVH is fully considered. For example, when the vehicle is in a low-speed state, a lower engine speed is adopted to reduce noise and vibration and improve the ride comfort; while in a high-speed situation, a higher engine speed is used to ensure sufficient power generation power supply. This solution can effectively supplement the battery power for the entire driving journey to ensure the normal driving of the vehicle to a certain extent.

[0038] However, in the entire driving cycle, the prior art needs to comprehensively balance the impact of NVH and power generation efficiency, and there is an irreconcilable contradiction between the two. As a subjective feeling, NVH has a crucial impact on the driver's driving experience. In order to reduce NVH, the engine speed and power output often need to be restricted, but this will lead to a decrease in power generation efficiency because the engine often cannot operate in the best efficiency range under low-speed or power-following conditions, thus reducing the power generation efficiency.

[0039] Due to the difficulty in finding a perfect balance between NVH and power generation efficiency, NVH will inevitably have a certain impact on the driver throughout the journey. For example, in some working conditions, increasing the engine speed to ensure power generation efficiency may lead to an increase in vehicle interior noise and vibration, reducing the ride and handling comfort. At the same time, the low power generation efficiency in some working conditions will directly affect the fuel consumption performance. The range extender consumes fuel during power generation. If the power generation efficiency is low, it means that more fuel needs to be consumed to generate the same amount of electricity, thus increasing the vehicle's usage cost and not conforming to the development trend of energy conservation and emission reduction.

[0040] In summary, the existing power generation control strategies are relatively fixed, lacking a mechanism for dynamic optimization according to real-time road conditions, and unable to adjust the vehicle's power generation state and power generation effect in a timely and accurate manner.

[0041] To solve the above technical deficiencies, the inventor provides a range-extended vehicle power generation method, system, and device based on a scenario mode.

[0042] The following further describes the present invention in detail with reference to the accompanying drawings: In a first aspect, an embodiment of the present invention provides a range-extended vehicle power generation method based on a scenario mode, as Figure 1 shown, including: S101. Preset travel scenario modes, formulate a power generation plan for the vehicle in the scenario mode, and use the power generation plan to enable the vehicle to generate power; Exemplarily, this process is mainly based on the user's travel needs to preset the vehicle's travel scenario modes. From the perspective of travel, it can include daily travel scenario modes and single travel scenario modes; among them, the daily travel scenario mode is mainly the user's daily round-trip commuting route travel scenario. The round-trip route is specifically from the user's own residence to the company location for work, or from the work location to the user's own residence; in this daily travel scenario mode, the specific departure time point or departure time interval of the user's daily commuting route, as well as the specific locations of the departure place and the destination, can be preset, and specifically, the parking positions of the vehicle's departure point and destination are the garage or outdoor parking lot. In the above preset steps, the daily travel scenario mode is designed for the two-way routes of users' daily commuting to and from work, accurately covering the main travel scenarios of most office workers. By presetting the routes from the place of residence to the workplace and vice versa, it is possible to plan the power generation scheme in advance, fully considering various factors during the commute, such as road conditions and traffic flow, to ensure that the vehicle has sufficient battery power during the commute to meet the daily driving needs, greatly improving the convenience and reliability of users' commuting. Presetting the specific departure time point or time interval, as well as the specific locations of the departure and destination (including the parking location being a garage or outdoor parking lot), makes the power generation scheme more in line with the actual travel arrangements of users. For example, the battery state and power generation power can be adjusted in advance according to the departure time to cope with the traffic conditions and power consumption demands at different time periods; knowing the parking location information helps to plan the charging or energy management strategy after the vehicle arrives at the destination.

[0043] During the operation of the above steps, users only need to preset the travel scenario mode to automatically match the corresponding power generation scheme, without the need for users to manually perform complex settings. This simplified operation process reduces the user's usage threshold and improves the operation convenience, enabling users to more easily enjoy the travel convenience brought by range-extended vehicles. In addition, intelligent reminders and guidance can be provided to users in advance according to the preset departure time and route information; for example, reminding users of the vehicle's battery state and whether charging is required in advance before departure; displaying the remaining battery power and estimated arrival time in real time during the driving process, so that users have a clearer understanding of the journey.

[0044] Furthermore, a reasonable power generation scheme can ensure that the vehicle always maintains a stable power supply during driving, avoiding a decrease in vehicle power or electronic device failures caused by insufficient battery power, which is crucial for improving the vehicle's performance and reliability. Especially during long-distance commuting or in complex road conditions, a stable power supply can ensure the safe driving of the vehicle.

[0045] After the above information is preset, use the preset vehicle travel scenario mode to calculate the power required for the vehicle to travel in this travel scenario mode; specifically, the total mileage, travel time, road section congestion situation, and specific time to reach the destination of this two-way route can be obtained based on this information, so as to calculate the power required for the vehicle to complete the two-way route. Then, the vehicle power consumption and the current remaining power of the vehicle are counted, and the power required for the vehicle to travel in this travel scenario mode is compared with the vehicle power consumption and the current remaining power of the vehicle to calculate the current power generation demand of the vehicle and set an offset. Through the above steps, the power required for the vehicle to complete the two-way route can be accurately calculated. This accurate power estimation avoids the problems of itinerary interruption caused by insufficient power or energy waste caused by excessive power, making the vehicle energy management more scientific and reasonable; secondly, comparing the power required for the vehicle to travel in this travel scenario mode with the vehicle power consumption and the current remaining power can understand the power supply and demand status of the vehicle in real time. Calculating the current power generation demand of the vehicle and setting an offset based on the comparison result can dynamically adjust the power generation power and power generation time to ensure that the vehicle's power demand can be met in different driving stages and improve energy utilization efficiency.

[0046] In terms of vehicle driving experience, since the vehicle has accurately calculated the power required for travel and the power generation demand based on the preset information before the user's daily commute, the user does not need to worry about the problem of insufficient power, enhancing the confidence and sense of security of travel; secondly, the power calculation and related data recording in each travel scenario mode accumulate rich travel data for the vehicle, including travel mileage, power consumption, power generation demand, etc. These data are of great significance for analyzing the energy consumption characteristics and performance of the vehicle, and can also further improve the intelligent level of the vehicle. Setting an offset for the power generation demand reserves a certain amount of power space for emergencies. For example, when unexpected situations such as traffic control and road construction cause an extension of travel time or an increase in power consumption, the offset can ensure that the vehicle has enough power to complete the journey, improving the vehicle's ability to cope with emergencies. During actual driving, road conditions and driving conditions may change. By comparing the power demand and the remaining power in real time and adjusting in combination with the offset, it is possible to flexibly adapt to these changes, timely adjust the power generation strategy, ensure that the vehicle is always in the best power state, and ensure the smooth progress of the journey.

[0047] The single-trip travel scenario mode mainly refers to the single-route travel scenario for users. Here, the single route specifically refers to a one-way route or a single trip route. For example, it can be the one-way route from the preset departure place to the destination when the user is on a self-driving tour, or the one-way route from the preset departure place to the destination when the user goes out temporarily. In this single-route travel scenario, similar to the daily travel scenario mode, the specific departure time point or time interval, as well as the specific locations of the departure place and the destination, can also be set. Moreover, it is specific to the parking positions of the vehicle's starting point and destination, which can be a garage or an outdoor parking lot. Then, based on the preset single-route travel scenario information, the total mileage, driving time, road congestion situation of this single route, and the specific time to reach the destination are obtained, so as to calculate the power required for the vehicle to complete the single route, and the vehicle power consumption and the current remaining power of the vehicle are counted. The power required for the vehicle to travel in this travel scenario mode is compared with the vehicle power consumption and the current remaining power of the vehicle to calculate the current power generation requirement of the vehicle and set the offset.

[0048] In the above steps, the single-route travel scenario mode covers various one-way travel scenarios such as users' self-driving tours and temporary outings. Whether it is a long-planned long-distance self-driving tour or a short-distance trip for temporary business decided on the spur of the moment, users can preset this mode to let the vehicle plan the power generation plan in advance, meet different travel needs, and increase the flexibility and applicability of vehicle use. Specifically, for each different single-route travel, users can set the specific departure time point or interval, as well as the specific locations of the departure place and the destination (including the parking position). This personalized setting enables the power generation plan to accurately match the actual situation of each trip and provides more considerate travel services for users.

[0049] Furthermore, after the above two travel scenario modes are preset, based on the distance between the departure place and the destination set by the user and the predicted congestion time provided by the map, the power required for the entire driving process is calculated based on the global positioning system. Combining the vehicle's overall power consumption and the current power, the required power generation is calculated and the offset is set. For example: Whether it is the daily travel scenario mode or the single-trip travel scenario mode, the total mileage of the travel route is 50 km, the real-time traffic condition of this travel route is normal without congestion, the total battery capacity of the vehicle is 40 kWh, and the current remaining power of the vehicle is 20% of the total power. Considering the working conditions when the state of charge (SOC) is below 90% (power generation is not considered above 90%), the calculation formula for the target power generation of the vehicle can be: Target power generation = min{(SOE corresponding to 90% SOC minus SOE corresponding to actual SOC), [min(SOE corresponding to actual SOC minus SOE corresponding to 50% SOC) + electricity consumption required for the journey in kwh minus electricity corresponding to the current actual SOC in kwh)]}. If the average power consumption of the vehicle is 16 kwh / 100 km, then the required power generation = 8 kwh + offset. The initial value of offset is 1 kw. After the engine starts generating power, it can be calibrated by looking up the table based on the remaining power generation duration.

[0050] Where: SOC: State of Charge, the state of charge of the battery, ranging from 0 to 100% SOE: State of Energy, that is, the energy state It should be noted that if the calculated target power generation of the vehicle is negative, then take 0, indicating that the engine does not need to start generating power.

[0051] Furthermore, according to the departure time set by the user, 15 - 30 (min) in advance is used as the power generation end time. According to the number of power generations and the maximum power generation time per single time, the power generation start time can be obtained. When the power generation start time arrives, the VCU (Vehicle Control Unit) is responsible for waking up the vehicle and controlling the engine to start generating power; for example, if the user's departure time is 8 am, according to the travel distance of 50 km, normal road conditions without congestion, the total battery capacity is 40 kwh, the current remaining battery power of the vehicle is 20% of the total power, and the average power consumption of the vehicle is 16 kwh / 100 km, the calculated power generation is 9 kwh, and the power generation power is calculated to be 33 kw based on the open environment. The calculated power generation time is about 14 min, which is less than 15 min. There is no need to pause in the middle to wait for the surrounding environment to improve and the front engine compartment to cool down. If the power generation is completed half an hour in advance, then this scenario mode needs to be woken up at about 7:16. The VCU controls the whole vehicle to generate power at a power of 33 kw. When there is no abnormality monitored in the middle, the power generation is completed at 7:30.

[0052] In the above steps, according to the departure time set by the user, 15 - 30 minutes in advance is set as the power generation end time, and the power generation start time is accurately calculated, which can ensure that the vehicle has sufficient power when departing to meet the driving requirements. At the same time, by accurately calculating the power generation amount and power generation time, the energy waste caused by excessive power generation is avoided, and the energy utilization efficiency is improved. The VCU is responsible for waking up the vehicle when the power generation start time arrives, enabling each system of the vehicle to enter the working state in advance. This can reduce the delay when the vehicle starts, improve the response speed of the vehicle, allow the user to quickly drive the vehicle onto the road when departing, save the waiting time, and improve the travel efficiency. By planning the power generation time and power in advance, the VCU can quickly control the engine to start generating power without complex settings and adjustments when departing. This fast response mechanism ensures that the vehicle completes the power generation preparation in a short time, providing convenience for the user's travel.

[0053] During the power generation process, the VCU will monitor the power generation status in real time to ensure that there is no abnormality in the power generation process. Once an abnormal situation is detected, the VCU can take timely measures, such as adjusting the power generation power, stopping power generation, etc., to ensure the safety and stability of the power generation process and avoid affecting the normal use of the vehicle due to power generation failures.

[0054] Finally, during the preset process of the above two travel scenario modes, it can be specifically operated based on a mobile terminal or an in - vehicle computer. The mobile terminal can be one of a mobile phone, a tablet computer, a smart watch, or a smart bracelet. A mobile phone is a commonly used device that people carry with them daily, with powerful functions and a convenient operation interface. Users can quickly preset the vehicle travel scenario mode through the mobile phone at any time and any place.

[0055] The tablet computer has a larger screen and a more comfortable operation experience, and is suitable for detailed scenario mode settings in relatively fixed places such as at home or in the office. Users can more intuitively view vehicle parameters, map information, etc. on the tablet computer and make more refined adjustments, such as planning complex travel routes, setting multiple waypoints, etc. Smart watches and smart bracelets have the characteristics of portability and real - time performance. Users can quickly preset or switch the scenario mode through simple operations on the watch or bracelet without taking out their mobile phones. Finally, different users have different usage habits for mobile devices. Providing multiple mobile terminal options can cover a wider user group. Young users may be more inclined to use mobile phones or smart watches for operation, while some business people or elderly users may be more accustomed to using tablet computers. This diverse selection can meet the personalized needs of different users and improve the acceptance and usage frequency of users for the vehicle system.

[0056] Secondly, these mobile terminals can all perform real-time data synchronization with the vehicle's on-board computer via a network. For example, a map application on a mobile phone or tablet can transmit real-time road condition information to the on-board system, and the on-board system adjusts the power generation plan and driving route based on this information.

[0057] S102. Real-time sense the environmental information and gas information of the location where the vehicle is generating power, and dynamically adjust the vehicle's power generation strategy based on the environmental information and gas information. Exemplarily, to ensure that there is no impact on the surrounding environment and pedestrians during the vehicle's power generation process, based on the vehicle's own intelligent driving technology and various types of sensors and cameras installed on the vehicle body, and preset the engine speed and power generation power during the vehicle's power generation. For example: According to the engine's external characteristic curve, select the optimal power generation torque (power) corresponding to the speed. For example, within a distance of 3 meters from the vehicle and within a noise range of 80 decibels, the speed is 3200 rpm and the power generation power is 33 kw. The power generation speed and power can be calibrated according to the actual situation. According to the required power generation amount and the engine's optimal power generation power, calculate the required power generation duration. If the power generation duration is greater than 30 minutes, the number of power generation times needs to be calculated according to the parking position. Initially, in an indoor parking lot, there is a shutdown every 15 minutes, and the engine starts again after a 5-minute interval. In an outdoor parking lot, there is a shutdown every 30 minutes, and the engine starts again after a 5-minute interval. The specific time can be calibrated. During the vehicle's power generation process, when the sensors and cameras on the vehicle body sense that a pedestrian is approaching, the vehicle actively reduces the speed to reduce the power generation noise. Specifically, considering the relatively enclosed space and limited ventilation conditions in an indoor parking lot, a power generation strategy of shutting down every 15 minutes and starting again after a 5-minute interval is specified. This strategy can effectively control the running time and heat accumulation of the engine in a relatively small space, reduce potential safety hazards that may be caused by long-term power generation, such as the risk of fire caused by high temperature, and is also beneficial to reducing the indoor noise level.

[0058] For an outdoor parking lot, considering the better ventilation conditions, a strategy of shutting down every 30 minutes and starting again after a 5-minute interval is adopted. While ensuring the power generation efficiency, it reasonably utilizes the advantages of the outdoor environment, reduces the impact on the surrounding environment, and avoids excessive wear on the engine caused by frequent start-stop.

[0059] If power generation is carried out at night and the noise of the vehicle's power generation exceeds the specified standard, the power generation will automatically stop.

[0060] Meanwhile, in terms of gas information perception, the AQS perception on the vehicle body can monitor the carbon dioxide concentration value and nitrogen oxide pollutant concentration value at the location where the vehicle generates electricity in real time. When the concentration of these harmful gases exceeds the safety standard, it can quickly issue a warning. For example, during the vehicle's power generation process, if the carbon dioxide concentration increases due to poor ventilation or nitrogen oxide pollutants leak from the power generation equipment, AQS can detect it in time, remind and then stop the power generation to avoid safety accidents. At the same time, if AQS detects that the nitrogen oxide pollutant concentration at the vehicle's location is too high, it may mean that there is a potential pollution source or poor air quality in the area. At this time, the vehicle can adjust the power generation strategy, such as reducing the power generation power or pausing the power generation, to avoid excessive power generation in a bad gas environment, reduce damage to the power generation equipment, and also help reduce the further impact of pollutant emissions on the environment.

[0061] After the vehicle stops generating electricity, the vehicle body transmits a reminder of the generated power (available endurance) to the mobile terminal, enabling the user to have a clear understanding of the vehicle's power situation regardless of where they are, which is convenient for the user to plan subsequent trips or usage arrangements in advance.

[0063] In the third aspect, a mobile terminal is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned range-extended vehicle power generation method based on a scenario mode are implemented.

[0064] In the fourth aspect, a computer-readable storage medium is provided. The computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned range-extended vehicle power generation method based on a scenario mode are implemented.

[0065] In the fifth aspect, a computer program product is provided, including computer instructions, and the computer instructions direct a computing device to perform operations corresponding to the above-mentioned range-extended vehicle power generation method based on a scenario mode.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the scope of its protection.
