Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of whole vehicle power balance, and particularly relates to a range-extending vehicle power generation method, system and equipment based on a scenario mode. BACKGROUND

[0002] As a new energy vehicle type with unique advantages, the power generation scene of the range-extender electric vehicle mainly concentrates on the driving process. In this stage, the power generation system takes the realization of the lowest energy consumption, the best NVH (noise, vibration and harshness) performance and the satisfaction of the required power of the driver as the core target. Specifically, in the driving process of the vehicle, the system will detect the current power of the vehicle and the required power of the driver in real time, and when the power is insufficient or the driving power cannot meet the demand, the range-extender system will start to supply power to the battery or directly to the driving motor.

[0003] At present, the range-extender vehicle generally adopts the power following or uses the fixed speed point power generation strategy in the driving process. The power following strategy can adjust the power generation power in real time according to the required power of the driver, and the fixed speed point power generation strategy is to generate power at a specific engine speed. In the power generation process, the influence of the engine speed on the NVH is fully considered. For example, when the vehicle is in a low speed state, a lower engine speed is used to reduce the noise and vibration and improve the riding comfort; and in the high speed case, a higher engine speed is used to ensure the sufficient supply of the power generation power. This scheme can effectively supplement the power for the entire driving trip to a certain extent and ensure the normal driving of the vehicle.

[0004] However, in the entire driving cycle, the existing technology needs to comprehensively balance the NVH influence and the power generation efficiency, and there is a contradiction between the two that is difficult to reconcile. As a subjective feeling, the NVH has a crucial influence on the driving experience of the driver. In order to reduce the NVH, it is often necessary to limit the speed and power output of the engine, but this will lead to the decrease of the power generation efficiency, because the engine cannot be in the best efficiency range in the low speed or power following condition, thereby reducing the power generation efficiency.

[0005] Due to the difficulty in finding a perfect balance point between the NVH and the power generation efficiency, the NVH will inevitably have a certain influence on the driver in the entire driving process. For example, in some working conditions, in order to ensure the power generation efficiency, the engine speed is increased, which may cause the increase of the in-vehicle noise and vibration and the decrease of the riding comfort. At the same time, the low power generation efficiency in some working conditions will directly affect the fuel consumption performance. The range-extender needs to consume fuel in the power generation process, and if the power generation efficiency is low, it means that more fuel needs to be consumed to generate the same power, thereby increasing the use cost of the vehicle and not meeting the development trend of energy saving and emission reduction.

[0006] In summary, the existing power generation control strategy is relatively fixed, lacks a dynamic optimization mechanism according to real-time road conditions, and cannot timely and accurately adjust the power generation state and power generation effect of the vehicle. SUMMARY

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] As a new energy vehicle type with unique advantages, the extended-range electric vehicle mainly focuses on the power generation scene in the driving process. In this stage, the power generation system aims to achieve the lowest energy consumption, the best NVH (Noise, Vibration and Harshness) performance and the power required by the driver. Specifically, during the driving process, the system will detect the current power of the vehicle and the power required by the driver in real time. When the power is insufficient or the driving power cannot meet the demand, the extended-range system will start to charge the battery or directly power the drive motor.

[0060] At present, the extended-range vehicle generally adopts power following or uses a fixed speed point power generation strategy during driving. The power following strategy can adjust the power generation power in real time according to the demand power of the driver, while the fixed speed point power generation strategy generates power at a specific engine speed. In the power generation process, the influence of engine speed on NVH is fully considered. For example, when the vehicle is in a low speed state, a lower engine speed is used to reduce noise and vibration and improve ride comfort; while in high speed conditions, a higher engine speed is used to ensure sufficient supply of power generation power. To some extent, this scheme can effectively supplement the power for the entire driving trip and ensure the normal driving of the vehicle.

[0061] However, in the entire driving cycle, the existing technology needs to balance the NVH influence and the power generation efficiency, which are difficult to reconcile. NVH, as a subjective feeling, has a crucial influence on the driving experience of the driver. In order to reduce NVH, the engine speed and power output are often limited, but this will lead to a decrease in power generation efficiency, because the engine cannot be in the best efficiency range under low speed or power following conditions, thereby reducing the power generation efficiency.

[0062] Due to the difficulty in finding a perfect balance point between NVH and power generation efficiency, NVH inevitably affects the driver during the entire trip. For example, in some working conditions, in order to ensure the power generation efficiency, the engine speed is increased, which may cause the increase of noise and vibration in the vehicle, 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 extended-range device needs to consume 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 power, thereby increasing the use cost of the vehicle and not meeting the development trend of energy saving and emission reduction.

[0063] In summary, the existing power generation control strategy is relatively fixed and lacks a dynamic optimization mechanism according to real-time road conditions, which cannot timely and accurately adjust the power generation state and effect of the vehicle.

[0064] In order to solve the above technical defects, the inventors provide an extended-range vehicle power generation method, system and device based on scenario mode.

[0065] The application will be described in further detail below with reference to the drawings:

[0066] In a first aspect, an embodiment of the application provides a range-extending vehicle power generation method based on a scenario mode, as shown in the following formula (I): Figure 1 The method comprises the following steps:

[0067] S101, preset a travel scenario mode, formulate a power generation scheme for the vehicle under the scenario mode, and use the power generation scheme to make the vehicle generate power; for example, the travel scenario mode of the vehicle is preset based on the user's travel demand. From the perspective of travel, it can include a daily travel scenario mode and a single travel scenario mode; the daily travel scenario mode is mainly for the user's daily two-way route travel scenario from the user's own residence to the company location or from the company location to the user's own residence; in this daily travel scenario mode, the specific departure time point or time interval of the user's daily commuting route, as well as the specific location of the departure and destination, can be preset, and the parking location of the vehicle departure point and destination is a garage or an outdoor parking lot.

[0068] In the above presetting step, the daily travel scenario mode is designed for the user's daily two-way commuting route, accurately covering the main travel scenarios of most commuters. By presetting the route from the residence to the workplace and vice versa, the power generation scheme can be planned in advance, taking into account various factors such as road conditions, traffic flow, etc. during the commute, ensuring that the vehicle has sufficient power during the commute to meet daily driving needs, greatly improving the convenience and reliability of the user's commute. By presetting the specific departure time point or time interval, as well as the specific location of the departure and destination (including the parking location as a garage or an outdoor parking lot), the power generation scheme is more tailored to the user's actual travel arrangements. For example, the battery state and power generation power can be adjusted in advance according to the departure time to cope with traffic conditions and power demand at different times; understanding the parking location information helps to plan charging or energy management strategies after the vehicle arrives at the destination.

[0069] During the above steps, the user only needs to preset the travel scenario mode, which can automatically match the corresponding power generation scheme without the user manually setting up complex settings. This simplified operation process reduces the user's threshold for use and improves the convenience of operation, allowing users to enjoy the travel convenience brought by the range-extending vehicle more easily. In addition, intelligent reminders and guidance can be provided in advance based on the preset departure time and route information; for example, reminding the user of the vehicle's power state and whether it needs to be charged in advance before departure; displaying the remaining power and estimated arrival time in real time during the journey, giving the user a clearer understanding of the journey.

[0070] Moreover, a reasonable power generation scheme can ensure that the vehicle always maintains stable power supply during driving, avoiding power decline or electronic device failure due to insufficient power, which is crucial for improving the performance and reliability of the vehicle, especially in long-distance commuting or complex road conditions. Stable power supply can ensure the safe driving of the vehicle.

[0071] When the above information preset is completed, the required power of the vehicle in the travel scenario mode is calculated using the preset vehicle travel scenario mode. Specifically, the total mileage, driving time, road congestion, and specific time of arrival at the destination of the two-way route can be obtained from the information, so as to calculate the required power of 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 required power of the vehicle in the 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 the offset. Through the above steps, the required power of the vehicle to complete the two-way route can be accurately calculated. This accurate power estimation avoids the problem of insufficient power leading to interrupted travel or excessive power causing energy waste, making the vehicle energy management more scientific and reasonable. Secondly, comparing the required power of the vehicle in the travel scenario mode with the vehicle power consumption and the current remaining power can help to understand the power supply and demand situation of the vehicle in real time. According to the comparison result, the current power generation demand of the vehicle is calculated and the offset is set, which can dynamically adjust the power generation power and time to ensure that the power demand of the vehicle can be met in different driving stages, improving the energy utilization efficiency.

[0072] In terms of vehicle driving experience, since the user performs daily commuting, the vehicle has accurately calculated the required power and power generation demand according to the preset information, so the user does not need to worry about the problem of insufficient power, enhancing the confidence and safety of travel. Secondly, the power calculation and related data recording in each travel scenario mode accumulate rich travel data for the vehicle, including driving mileage, power consumption, power generation demand, etc., which is of great significance for analyzing the energy consumption characteristics and performance of the vehicle, and can further improve the intelligent level of the vehicle. The offset of the power generation demand reserves a certain amount of power space to deal with unexpected situations. For example, when encountering unexpected situations such as traffic control, road construction, etc., which cause the driving time to be prolonged or the power consumption to be increased, the offset can ensure that the vehicle has enough power to complete the journey, improving the ability of the vehicle to deal with unexpected situations. In the actual driving process, the 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, these changes can be flexibly adapted, the power generation strategy can be adjusted in time, and the vehicle can always be in the best power state to ensure the smooth progress of the journey.

[0073] The single travel scenario mode is mainly for the single route travel scenario of the user, and the single route specifically refers to a one-way route or a single trip route. For example, it can be a single trip route from the preset starting point to the destination when the user goes on a self-driving tour, or a single trip route from the preset starting point to the destination when the user temporarily goes out. In this single route travel scenario, the specific departure time point or interval, the specific location of the starting point and the destination, and the specific parking location of the vehicle at the starting point and the destination are set, which are the garage or outdoor parking lot. Then, according to the preset single route travel scenario information, the total mileage, driving time, road congestion situation and specific time of reaching the destination of the single route are obtained, so as to calculate the required power for the vehicle to drive the single route, and the vehicle power consumption and the current remaining power of the vehicle are counted. The required power for the vehicle to drive in this travel scenario mode is compared with the vehicle power consumption and the current remaining power of the vehicle, and the current power generation demand of the vehicle is calculated and an offset is set.

[0074] In the above steps, the single route travel scenario mode covers various one-way travel scenarios such as self-driving tour and temporary outing. Whether it is a long self-driving tour planned for a long time or a short outing decided temporarily, the user can preset this mode to let the vehicle plan the power generation scheme in advance to meet different travel needs and increase the flexibility and applicability of the vehicle. Specifically, the user can set the specific departure time point or interval, and the specific location of the starting point and the destination (including the parking location) for each different single route travel. This personalized setting enables the power generation scheme to accurately match the actual situation of each trip and provides more considerate travel services for the user.

[0075] Further, after the above two travel scenario modes are preset, the required power for the entire driving process is calculated based on the global positioning system according to the distance between the starting point and the destination set by the user and the predicted congestion time provided by the map. The required power generation amount is calculated in combination with the total vehicle power consumption and the current power, and an offset is set. For example:

[0076] Whether it is the daily travel scenario mode or the single travel scenario mode, the total mileage of the travel route is 50km, the real-time traffic condition of the travel route is normal road condition without congestion, the total capacity of the vehicle battery is 40kwh, and the current remaining power of the vehicle is 20% of the total power. For the SOC below 90%, the target power generation amount of the vehicle can be calculated by the following formula:

[0077] Target power generation = min{ (SOE of 90% SOC - SOE of actual SOC), [min(SOE of actual SOC - SOE of 50% SOC) + kwh of power needed for the trip - kwh of power corresponding to current actual SOC]}, if the average power consumption of the vehicle is 16 kwh / 100km, then the power generation needed = 8 kwh + offset, the initial value of offset is 1 kw, after the engine starts to generate power, the remaining power generation time is looked up to be calibrated.

[0078] SOC: State of Charge, battery state of charge, range 0-100%

[0079] SOE: State of Energy, energy state

[0080] It is worth noting that if the target power generation of the vehicle is calculated to be negative, it is taken as 0, indicating that the engine does not need to start power generation.

[0081] Further, according to the user's set departure time, 15-30 (min) is taken as the end time of power generation, and the start time of power generation is obtained according to the number of power generations and the longest time of single power generation. When the start time of power generation is reached, the VCU (Vehicle Control Unit, vehicle controller) is responsible for waking up the vehicle and controlling the start of the engine to generate power; for example, if the user's departure time is 8:00 am, the travel distance is 50km, the normal road condition is no congestion, the total capacity of the battery is 40kwh, the current remaining power of the vehicle is 20% of the total power, the average power consumption of the vehicle is 16kwh / 100km, the calculated power generation is 9kwh, the power generation power is calculated according to the open environment as 33kw, the power generation time is about 14min, which is less than 15min, and there is no need to pause and wait for the surrounding environment to improve and the temperature inside the front engine compartment to drop during the process. According to the half hour in advance to complete the power generation, this scenario mode needs to wake up at about 7:16, the VCU controls the vehicle to generate power at 33kw, and when no abnormality is monitored in the middle, the power generation is completed at 7:30.

[0082] In the above steps, according to the user's departure time, the end time of power generation is set 15-30 minutes in advance, and the start time of power generation is accurately calculated, which can ensure that the vehicle has enough power at the time of departure to meet the driving needs. At the same time, by accurately calculating the power generation and power generation time, the energy waste caused by excessive power generation is avoided, and the energy utilization efficiency is improved. VCU is responsible for waking up the vehicle when the power generation start time arrives, so that each system of the vehicle can enter the working state in advance, which can reduce the delay when the vehicle starts and improve the response speed of the vehicle, so that the user can quickly drive the vehicle on the road when leaving, saving waiting time and improving travel efficiency. By planning the power generation time and power in advance, VCU can quickly control the start of engine power generation without complex settings and adjustments at the time of departure. This fast response mechanism ensures that the vehicle completes the power generation preparation in a short time and provides convenience for the user's travel.

[0083] During power generation, VCU will monitor the power generation state in real time to ensure that the power generation process is normal. Once an abnormal situation is detected, VCU can take timely measures such as adjusting the power generation power or stopping power generation to ensure the safety and stability of the power generation process and avoid affecting the normal use of the vehicle due to power generation failure.

[0084] Finally, in the preset process of the above two travel scenario modes, mobile terminals or vehicle-mounted computers can be used for operation. Mobile terminals can be one of mobile phones, tablet computers, smart watches or smart bracelets. Mobile phones are commonly used devices that people carry with them every day, with powerful functions and convenient operation interfaces. Users can quickly preset the vehicle travel scenario mode at any time and in any place through the mobile phone.

[0085] Tablet computers have larger screens and more comfortable operation experience, making them suitable for detailed scenario mode settings in relatively fixed places such as homes or offices. Users can more intuitively view vehicle parameters, map information, etc. on the tablet computer and make more detailed adjustments, such as planning complex travel routes and setting multiple waypoints. Smart watches and smart bracelets have portability and real-time features, allowing users to quickly preset or switch scenario modes without having to take out their phones and perform simple operations on the watch or bracelet. Finally, different users have different habits when using mobile devices, and providing multiple mobile terminal options can cover a wider range of user groups. Young users may prefer to use mobile phones or smart watches for operation, while some business people or older users may be more accustomed to using tablet computers. This diverse selection can meet the individual needs of different users and improve their acceptance and frequency of use of the vehicle system.

[0086] Secondly, these mobile terminals can be synchronized with the vehicle's on-board computer in real time, for example, the map application on the mobile phone or tablet can transmit real-time traffic information to the vehicle system, and the vehicle system can adjust the power generation scheme and driving route according to the information.

[0087] S102, real-time sensing of environmental information and gas information of the position where the vehicle is located during power generation, and dynamically adjusting the vehicle power generation strategy based on the environmental information and gas information; for example, in order to ensure that the vehicle has no influence on the surrounding environment and pedestrians during power generation, based on the vehicle's own intelligent driving technology and various types of sensors and cameras installed on the vehicle body, and the engine speed and power generation power during vehicle power generation are preset; for example: according to the engine external characteristic curve, the best power generation torque (power) corresponding to the speed is selected, such as within a distance of 3 meters from the vehicle and 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 capacity and the best power generation power of the engine, the power generation time is calculated. If the power generation time is greater than 30 minutes, the power generation frequency needs to be calculated according to the parking position. The indoor parking lot is stopped once every 15 minutes, and the engine is started again after 5 minutes; the outdoor parking lot is stopped once every 30 minutes, and the engine is started again after 5 minutes. The specific time can be calibrated. During the vehicle power generation process, when the sensors and cameras on the vehicle body sense that pedestrians are approaching, the vehicle actively reduces the speed, which has realized the reduction of power generation noise; specifically, considering the characteristics of the relatively closed space and limited ventilation conditions of the indoor parking lot, the power generation strategy of stopping once every 15 minutes and starting again after 5 minutes is specified. This strategy can effectively control the running time and heat accumulation of the engine in a relatively small space, reduce the safety hazards that may be caused by long-time power generation, such as the risk of fire caused by high temperature, and is also conducive to reducing indoor noise levels.

[0088] For outdoor parking lots, considering the good ventilation conditions, the strategy of stopping once every 30 minutes and starting again after 5 minutes is adopted, which not only ensures the power generation efficiency, but also reasonably utilizes the outdoor environment advantages, reduces the influence on the surrounding environment, and avoids the excessive wear and tear of the engine caused by frequent start-stop.

[0089] If power generation is carried out at night, if the noise of the vehicle power generation exceeds the specified standard, the power generation is automatically stopped.

[0090] Meanwhile, in terms of gas information sensing, the AQS sensing on the vehicle body can monitor the carbon dioxide concentration value and nitrogen oxide pollutant concentration value in the location where the vehicle is located in real time, and can quickly issue a warning when the concentration of these harmful gases exceeds the safety standard. For example, if the carbon dioxide concentration increases due to poor ventilation during the vehicle power generation process, or the nitrogen oxide pollutant leaks from the power generation equipment, the AQS can timely discover and remind and then stop power generation to avoid safety accidents. At the same time, if the AQS monitors that the nitrogen oxide pollutant concentration in the location where the vehicle is located 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 suspending the power generation, to avoid excessive power generation in a bad gas environment and reduce damage to the power generation equipment, while also helping to reduce the further impact of pollutant emissions on the environment.

[0091] When the vehicle stops power generation, the vehicle body transmits the generated power (available endurance) to the mobile terminal to remind the user, so that the user can know the power situation of the vehicle no matter where he is, and the user can conveniently plan the subsequent travel or use arrangement in advance.
