Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to an energy control method, device and vehicle. Background Art

[0002] In the prior art, the energy control strategy of the extended-range electric vehicle requires that a portion of the available power be reserved from the total available power to ensure that the total available power will not be reduced due to the start-up of the range extender during driving, thereby resulting in insufficient energy to drive the vehicle. The reserved available power is also required to drive the generator control device GCU (Generator Control Unit) to ensure that the power battery can be charged when the remaining power SOC (State of Charge) of the vehicle battery is low, to prevent the vehicle SOC from continuously decreasing due to reasons such as intense driving, resulting in a further reduction in available power. However, in the actual driving process, when the range extender is started, there is a situation where the instantaneous power is too large. When the instantaneous power exceeds the reserved available power, it may cause the user to have insufficient power when driving and accelerating, thereby posing a certain driving risk. However, the existing energy control strategy cannot predict the energy consumed by the vehicle on the road to be driven, nor can it avoid the generation of driving risks. It can only use the above-mentioned reserved power method to greatly reduce the use space of the actual available power and cannot give full play to the vehicle's power. Summary of the invention

[0003] In view of this, the embodiments of the present application provide an energy control method, device and vehicle to solve the problem in the prior art that a portion of the vehicle's total energy is reserved for starting the range extender, resulting in the inability to fully utilize the vehicle's power.

[0005] Obtaining the vehicle's navigation information, the vehicle's remaining total energy at the navigation starting point, and historical driving habit information. The navigation information includes the navigation starting point, navigation end point, and driving path;

[0006] Based on navigation information, remaining total energy and historical driving habit information, the remaining energy curve of the vehicle is predicted. The remaining energy curve is used to represent the corresponding relationship between the position of the vehicle in the driving path and the remaining energy of the vehicle.

[0007] Determine the coordinate point of the vehicle in the driving path corresponding to the remaining energy curve when the energy threshold is turned on, and use the coordinate point as the turning-on position;

[0008] When the vehicle drives to the on position, the vehicle's range extender is turned on.

According to the energy control method provided in the present application, the remaining energy can be used as the energy to drive the vehicle, thereby improving the power of the vehicle, and according to the predicted remaining energy curve, turning on the range extender when the vehicle drives to the turning-on position, so as to eliminate the driving risk caused by the excessive instantaneous power when the range extender is turned on during driving, which exceeds the reserved power, thereby improving the safety of the extended-range vehicle.

[0021] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0022] An energy control method and device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0023] Figure 1 is a flow chart of an energy control method provided in an embodiment of the present application. Figure 1 As shown, the energy control method comprises the following steps:

[0024] S101, obtaining navigation information of the vehicle, the remaining total energy of the vehicle at the navigation starting point, and historical driving habit information of the vehicle;

[0025] S102, predicting a remaining energy curve of the vehicle based on the navigation information, the remaining total energy and the historical driving habit information;

[0026] S103, determining a coordinate point of the vehicle in the driving path corresponding to the remaining energy curve when the energy threshold is turned on, and using the coordinate point as the turn-on position;

[0027] S104, when the vehicle reaches the on position, the range extender of the vehicle is turned on.

[0028] In some embodiments, the vehicle navigation information set by the user is obtained, and the navigation information includes specific navigation information such as the driving route selected by the user, the navigation starting point, and the navigation end point, and the remaining total energy and historical driving habit information of the vehicle at the navigation starting point are obtained at the same time. The historical driving habit information includes driving habit information such as historical average energy consumption and historical average vehicle speed.

[0029] The vehicle's remaining energy curve is predicted based on navigation information, remaining total energy and historical driving habit information, where the remaining energy curve is composed of the driving power consumption required for each road section category corresponding to the predicted vehicle's driving path, and the driving power consumption required for each road section category corresponding to the vehicle's driving path is obtained based on big data statistics.

[0030] The energy remaining curve is used to characterize the corresponding relationship between the vehicle's position in the driving path and the vehicle's remaining energy. The predicted energy remaining curve can be drawn with the position in the driving path as the horizontal axis and the remaining energy as the vertical axis, or with the position in the driving path as the vertical axis and the remaining energy as the horizontal axis.

[0031] Determine the coordinate point of the corresponding vehicle in the driving path when the remaining energy of the remaining energy curve is equal to the start-up energy threshold, and use the coordinate point as the start-up position. When the vehicle travels to the start-up position, turn on the vehicle's range extender.

[0032] In the energy control method provided in the present application, turning on the range extender in the first position based on the predicted total energy consumption can eliminate the driving risks caused by excessive instantaneous power when the range extender is turned on during driving, which may exceed the reserved power, thereby improving the safety of the extended-range vehicle.

[0033] In some embodiments, determining the coordinate point of the vehicle in the driving path when the remaining energy curve is at the opening energy threshold, and before using the coordinate point as the opening position, further includes:

[0034] Determine whether the remaining energy corresponding to the navigation end point on the remaining energy curve is less than the minimum energy threshold;

[0035] If so, the step of determining the coordinate point of the vehicle in the driving path when the remaining energy curve is at the opening energy threshold and using the coordinate point as the opening position is performed.

[0036] Determine the remaining energy corresponding to the navigation end point on the remaining energy curve, compare the remaining energy corresponding to the navigation end point with the minimum energy threshold, and if the comparison result is that the remaining energy corresponding to the navigation end point is less than the minimum energy threshold, determine the coordinate point of the vehicle in the driving path when the remaining energy is equal to the start-up energy threshold. If the comparison result is that the remaining energy corresponding to the navigation end point is not less than the minimum energy threshold, the start-up coordinates are not determined, and the range extender is kept off.

[0037] The minimum energy threshold is the minimum energy required to drive the vehicle.

[0038] In the energy control method provided in the present application, it is determined whether the range extender needs to be turned on based on the remaining energy curve and the remaining energy corresponding to the navigation end point, so that the remaining energy of the entire vehicle can provide energy for driving the vehicle as much as possible, without causing energy waste, so as to improve the economic applicability of the vehicle.

[0039] In some embodiments, before determining whether the remaining energy corresponding to the navigation end point on the remaining energy curve is less than a minimum energy threshold, the method further includes:

[0040] A minimum energy threshold is determined based on the current user-selected driving mode.

[0041] In an exemplary embodiment of the present application, if the navigation information does not include a location for charging the vehicle, the minimum energy threshold is determined based on the driving mode currently selected by the user. That is, when the two sides of the road on the driving route do not include a charging station or a home address, or when the navigation destination is not a charging station or a home address, or when it is determined based on the user's historical behavior data that the user has a low probability of charging the vehicle while driving, it is determined that the navigation information does not include a location for charging the vehicle, and the minimum energy threshold is determined based on the driving mode currently selected by the user.

[0042] In another exemplary embodiment of the present application, if the navigation information includes a location for charging the vehicle, the minimum energy threshold is determined according to the driving mode currently selected by the user. When the user has not selected the driving mode, the minimum energy threshold is a preset value, for example, the minimum energy threshold is 5%. Among them, the location for charging the vehicle included in the navigation information includes a charging station or a home address, that is, if the navigation end point is a charging station or a home address, or a charging station or a home address is included in the process from the navigation start point to the navigation end point, or it is determined based on the user's historical behavior data that the user has a high probability of charging the vehicle when passing a certain point, then it is determined that the navigation information includes a location for charging the vehicle. When the user has selected a driving mode, the minimum energy threshold is determined according to the minimum energy threshold corresponding to the driving mode.

[0043] According to the technical solution provided in the embodiment of the present application, the activation conditions of the range extender can be determined as much as possible while driving to the location where the vehicle is charged, so as to increase the pure electric driving mileage, thereby reducing fuel consumption, improving the economy of vehicle use, and protecting the environment.

[0044] In some embodiments, after determining whether the remaining energy corresponding to the navigation end point on the remaining energy curve is less than the minimum energy threshold, the method further includes:

[0045] Obtain starting energy for the range extender;

[0046] The sum of the startup energy and the minimum energy threshold is determined as the start-up energy threshold.

[0047] Get the starting energy of the range extender. The starting energy is pre-saved in the vehicle's configuration file. The starting energy is the energy required to start the range extender. Get the starting energy and calculate the sum of the starting energy and the minimum energy threshold as the start-up energy threshold. For example, if the starting energy is 3% of the vehicle's total energy and the minimum energy threshold is 5% of the vehicle's total energy, then the start-up energy threshold is 8%.

[0048] In the energy control method provided in the present application, if the remaining energy corresponding to the navigation end point on the remaining energy curve is less than the minimum energy threshold, the corresponding start-up energy threshold is determined, so that when the vehicle needs to turn on the range extender, the corresponding starting energy is reserved for turning on the range extender, while avoiding driving safety problems that may be caused by excessive instantaneous energy consumption when turning on the range extender, thereby improving the safety of driving the vehicle.

[0049] In some embodiments, it also includes:

[0050] When the navigation information includes a location for charging the vehicle, and the remaining energy corresponding to the navigation end point on the remaining energy curve is less than the minimum energy threshold, a prompt message is sent, and the prompt message is used to prompt the vehicle to charge;

[0051] If it is detected that the vehicle is charged, the remaining energy curve is corrected based on the remaining total energy after charging, navigation information and historical driving habit information, and the historical driving habit information includes historical average energy consumption and historical average vehicle speed.

[0052] In an exemplary embodiment of the present application, when the navigation information includes a location for charging the vehicle and the remaining energy corresponding to the navigation end point is less than a minimum energy threshold, a prompt message is sent to prompt the user to charge the vehicle and turn on the vehicle's range extender in the open position.

[0053] The vehicle's remaining total energy is detected in real time. If it is detected that the vehicle has been charged or is being charged, the remaining energy curve is corrected according to the total remaining energy after charging, navigation information and current historical driving habits. The current historical driving habit information is the historical driving habit information with the starting point of this navigation as the starting time, including the historical average energy consumption, the historical average vehicle speed and the historical consumed energy.

[0054] At the same time, if the user charges the vehicle before the vehicle reaches the opening position, the remaining energy corresponding to the navigation end point on the updated remaining energy curve is re-determined to be less than the minimum energy threshold. If so, the opening position is updated. If the vehicle has reached the opening position and has not been charged, the range extender is turned on at the opening position, and after charging is detected, the remaining energy curve and the opening position are updated according to the remaining total energy after charging.

[0055] According to the technical solution provided in the embodiment of the present application, the activation conditions of the range extender can be determined when the vehicle is traveling to a location where the vehicle can be charged, so as to increase the pure electric mileage, thereby reducing fuel consumption, improving the economy of vehicle use, and protecting the environment.

[0056] In some embodiments, based on the navigation information, the remaining total energy and the historical driving habit information, predicting the remaining energy curve of the vehicle includes:

[0057] Taking the remaining total energy as the starting point, the remaining energy curve of the vehicle is predicted based on each road section category appearing in the navigation information and the historical energy consumption corresponding to each road section category in the historical driving habit information.

[0058] The driving path of a vehicle from the navigation starting point to the navigation end point is composed of multiple road sections, and the multiple road sections are distinguished according to the driving route and the road section category. The road section category is a classification result of the multiple road sections. Among them, the road section category can be, for example, cement road section, asphalt road section, uphill mountain road section, downhill mountain road section, expressway section and other different road section categories.

[0059] The road characteristics of the driving route are obtained according to the navigation information, and the driving route is divided into multiple sections according to the comparison results between the pre-set road characteristics and combination rules and the road characteristics of the driving route. Each section has a corresponding section category, and the proportion of the distance corresponding to each section category in the total distance is determined.

[0060] The road section categories may be, for example, cement road sections, asphalt road sections, uphill mountain road sections, downhill mountain road sections, expressway sections, and other different road section categories.

[0061] Based on all road segment categories, the proportion of the distance corresponding to each road segment category in the total distance in the navigation information, and the historical energy consumption corresponding to each road segment category in the historical driving habit information of the vehicle, the remaining total energy corresponding to the navigation starting point is used as the starting point to predict the remaining energy curve of the vehicle. Among them, the historical driving habit information is the average energy consumption and average vehicle speed corresponding to all driving records of the vehicle.

[0062] In an exemplary embodiment of the present disclosure, the total distance of the navigation information is 100 km (kilometers), the driving route includes an uphill mountain road section, a downhill mountain road section and an asphalt road section, the distance corresponding to the uphill mountain road section is 20 km, the distance corresponding to the downhill mountain road section is 30 km, and the distance corresponding to the asphalt road section is 50 km. For example, an exemplary description is given:

[0063] The energy required for the vehicle to travel on each kilometer of uphill mountain road multiplied by the distance of the uphill mountain road (20KM) is used as the historical energy consumption of the vehicle in traveling on the uphill mountain road. The energy required for the vehicle to travel on each kilometer of downhill mountain road multiplied by the distance of the downhill mountain road (30KM) is used as the historical energy consumption of the vehicle in traveling on the downhill mountain road. The energy required for the vehicle to travel on each kilometer of asphalt road multiplied by the distance of the asphalt road (50KM) is used as the historical energy consumption of the vehicle in traveling on the asphalt road.

[0064] The energy required for the vehicle to travel on each unit road section is determined based on the statistical results of big data, and is the historical energy consumption corresponding to the case where the range extender is not turned on. The remaining energy curve of the vehicle is predicted based on the historical energy consumption of each road section category corresponding to the navigation information and historical driving habit information.

[0065] In the energy control method provided by the present application, the driving path included in the navigation information is divided into multiple sections according to the road section category, and the remaining energy curve is predicted according to the big data results of the historical energy consumption corresponding to each road section category in the historical driving habit information. The historical energy consumption determined according to the big data results can have a more accurate control of the total energy that the vehicle is about to consume. Combined with the historical driving habit information, the remaining energy curve can be more in line with the current user's driving habits, improve the user's driving experience, and meet the user's personalized needs.

[0066] In some embodiments, it also includes:

[0067] Obtain the real-time energy consumption of the vehicle when driving according to navigation information;

[0068] Based on the real-time energy consumption and the road section category corresponding to the real-time energy consumption, the remaining energy curve is corrected.

[0069] The navigation information can obtain the vehicle position in real time, and determine that the vehicle has traveled through the current section based on the navigation information, that is, the driving path of the vehicle from the starting point of a section to the end point corresponding to the section is taken as the traveled section, and the energy consumption corresponding to the traveled section is obtained, and the remaining energy curve is corrected based on the consumed energy.

[0070] In an exemplary embodiment of the present disclosure, a driving route includes an uphill mountain road section, a downhill mountain road section and an asphalt road section, the distance corresponding to the uphill mountain road section is 20KM, the distance corresponding to the downhill mountain road section is 30KM, and the distance corresponding to the asphalt road section is 50KM, and the order of the sections is section ① asphalt road 20KM, section ② uphill mountain road 10KM, section ③ asphalt road 5KM, section ④ uphill mountain road 5KM, section ⑤ downhill mountain road 10KM, section ⑥ asphalt road 15KM, section ⑦ uphill mountain road 5KM, section ⑧ downhill mountain road 20KM, section ⑨ asphalt road 15KM, for example, an exemplary description is given:

[0071] The remaining energy curve has been determined, and the vehicle is currently traveling on section ①. When the vehicle travels in the order of section ①, section ②, ... section ⑨, and has traveled 20 km, that is, it has finished traveling on section ① and started traveling on section ②, the energy consumed by the vehicle on section ① is obtained and recorded. Based on the energy consumed by the vehicle on section ① and the distance of section ①, the energy consumed per unit of the vehicle on the asphalt road is determined, and the part of the section where the vehicle has not traveled is corrected based on the energy consumed, that is, the energy consumed corresponding to sections ③, ⑥, and ⑨ is corrected to correct the remaining energy curve.

[0072] Similarly, when section ② is regarded as a traveled section, the remaining energy curve is corrected according to the above correction method, and the energy consumed by the vehicle traveling on section ② is recorded.

[0073] Each time the vehicle travels through a single road section corresponding to a road section category, the remaining energy curve is corrected once.

[0074] In the energy control method provided in the present application, the remaining energy curve is corrected once after each road section is traveled according to the order of appearance of the road section categories. The remaining energy curve can be corrected in real time according to the data obtained during this navigation process, thereby improving the real-time and accuracy of the remaining energy curve, thereby more accurately controlling the remaining energy of the vehicle.

[0075] In some embodiments, after the range extender is turned on, the method further includes:

[0076] If the current remaining energy is greater than the first energy threshold, the range extender is turned off;

[0077] If the current remaining energy is less than the second energy threshold, the power generation power of the range extender is increased.

[0078] The first energy threshold is greater than the minimum energy threshold, and the second energy threshold is less than the minimum energy threshold.

[0079] After the range extender is turned on, the remaining battery power is maintained within a range from a first energy threshold to a second energy threshold, wherein the first energy threshold is greater than a minimum energy threshold and the second energy threshold is less than the minimum energy threshold.

[0080] In an exemplary embodiment of the present disclosure, taking the case where the navigation information includes a location for charging the vehicle and the user has not selected a driving mode, the minimum energy threshold is 5% of the total battery power, the first energy threshold is 3% of the total battery power, and the second energy threshold is 7% of the total battery power as an example, it can be seen that the first energy threshold and the second energy threshold fluctuate by 2% based on the minimum energy threshold. If the remaining energy corresponding to the navigation end point on the remaining energy curve is less than 5%, a prompt message is sent to prompt the user that charging is required, and the remaining energy curve is corrected in real time during driving. If the remaining energy corresponding to the navigation end point on the remaining energy curve during the driving route is still less than 5%, the coordinate point of the vehicle in the driving path corresponding to the corrected remaining energy curve when the energy threshold is turned on is determined based on the corrected remaining energy curve and the turn-on energy threshold, the coordinate point is used as the turn-on position, and the range extender is turned on at the turn-on position.

[0081] After starting the range extender, the remaining energy corresponding to the navigation end point on the remaining energy curve is kept floating between 3% and 7%, and the range extender is controlled to generate electricity according to the corrected remaining energy curve and the actual power to drive the vehicle. When the remaining energy corresponding to the navigation end point on the remaining energy curve is greater than 7%, the range extender is turned off. When the remaining energy corresponding to the navigation end point on the remaining energy curve is less than 3%, the power generation power of the range extender is increased.

[0082] According to the technical solution provided in the embodiment of the present application, the activation conditions of the range extender can be determined as much as possible while driving to the location where the vehicle is charged, so as to increase the pure electric driving mileage, thereby reducing fuel consumption, improving the economy of vehicle use, and protecting the environment.

[0083] In another exemplary embodiment of the present disclosure, the navigation information does not include a location for charging the vehicle, or the navigation information includes a location for charging the vehicle and the user selects a driving mode, and the minimum energy threshold corresponding to the driving mode selected by the user is 8% of the total battery power, the first energy threshold is 6% of the total battery power, and the second energy threshold is 10% of the total battery power. For example, it can be seen that the first energy threshold and the second energy threshold fluctuate by 2% based on the minimum energy threshold. If the remaining energy corresponding to the navigation end point on the remaining energy curve is less than 8%, it is determined that the energy corresponding to the navigation end point on the remaining energy curve is less than the minimum energy threshold, the start position is determined, and the remaining energy curve is corrected in real time during driving. If the remaining energy corresponding to the navigation end point on the remaining energy curve during driving is still less than 8%, then according to the corrected remaining energy curve and the start energy threshold, the corrected remaining energy curve is determined at the start energy threshold, and the coordinate point of the vehicle corresponding to the corrected remaining energy curve at the start energy threshold in the driving path is determined, and the coordinate point is used as the start position, and the range extender is turned on at the start position.

[0084] After starting the range extender, the remaining energy corresponding to the navigation end point on the remaining energy curve is kept floating between 6% and 10%, and the range extender is controlled to generate electricity according to the corrected remaining energy curve and the actual power to drive the vehicle. When the remaining energy corresponding to the navigation end point on the remaining energy curve is greater than 10%, the range extender is turned off. When the remaining energy corresponding to the navigation end point on the remaining energy curve is less than 6%, the power generation power of the range extender is increased.

[0085] According to the technical solution provided in the embodiment of the present application, the activation conditions of the range extender can be determined during driving according to the driving mode selected by the user, so as to increase the pure electric mileage, thereby reducing fuel consumption, improving the economy of vehicle use, and protecting the environment.

[0086] In an exemplary embodiment of the present disclosure, if the navigation information set by the user is not obtained, it is determined that the user has not set the navigation information, and the remaining energy is obtained in real time. When the remaining energy is greater than a preset threshold, it is determined that the vehicle has strong power, indicating that the danger of the vehicle power decreasing is high, so more power is reserved, and the reserved power is used to start the range extender. When the remaining energy is not greater than the preset threshold, it is determined that the vehicle has weak power, indicating that the danger of the vehicle power decreasing is low, so less power is reserved, and the reserved power is used to start the range extender. The purpose of taking into account both power and safety can be achieved.
