[0043] Those skilled in the art can understand that Figure 1 the structure shown in

Figure 1As shown in the figure, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a driving mode adaptive adjustment program.

The driving mode adaptive adjustment device calls the driving mode adaptive adjustment program stored in the memory 1005 through the processor 1001 and executes the driving mode adaptive adjustment method provided by the embodiments of the present invention.

[0046] The embodiments of the present invention provide a driving mode adaptive adjustment method. Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of the driving mode adaptive adjustment method of the present invention.

[0047] In this embodiment, the driving mode adaptive adjustment method includes:

[0048] Step S10: Obtain the real-time vehicle driving state, and determine the driving road condition according to the real-time vehicle driving state.

[0049] It should be noted that the real-time vehicle driving state here refers to the vehicle speed, as well as the mileage, time, and navigation information within a certain period of time to obtain the driving state at the current moment. The system will determine the current driving road condition according to the driving conditions during this period. The determination of the driving road condition includes calculating the average speed using the driving mileage and time, and combining the navigation information to confirm the road conditions, etc. The determination of the driving conditions will provide a basis for the subsequent adjustment of the vehicle driving mode.

[0050] It should be understood that, according to a certain mileage or a certain time as a limit, the average speed of the vehicle at the current moment in the past period of time can be calculated. If the average speed is higher than the preset speed threshold, it can be considered that the road is unobstructed, and when the average speed is lower than the preset speed threshold, it can be considered that the road is congested. However, it should be noted that the two judgments here should not be judged with the same value. For example, when a vehicle is driving on an expressway or a national highway, because the road is relatively open and the vehicle vision is good over a long distance, the vehicle speed can generally reach 80 to 90 kilometers per hour. At this time, the road condition recognition result is definitely a clear section, and the speed of the clear section can be judged as The cutoff value is set to a specific value within the range or a slightly lower value, for example, the judgment threshold is set to 70 kilometers per hour. However, at this time, if the previous judgment threshold is applied to the judgment of whether there is congestion, it will be inappropriate. Due to congested road conditions, it is generally believed that the speed of the vehicle is far less than 70 kilometers per hour. Usually, the average speed of congested sections will be lower, about only 20 kilometers per hour. At this time, it can be found that the speed values ​​for judging congestion and judging smooth traffic should be set separately. Therefore, in fact, compared with congested sections and smooth sections, there will be some transition sections between the two situations on the actual driving road. In these sections, the system will not deliberately change the driving mode.

[0051] It is understandable that, generally speaking, the degree of road congestion in a small range is similar. That is to say, within a relatively small judgment time period, if the judgment result is congestion, then it can be considered that the road conditions within a certain distance are the same. Similarly, when the judgment result is unobstructed, the road conditions within a certain distance should also be unobstructed.

[0052] Step S20: Changing the driving mode of the vehicle based on the current vehicle parameters and the driving road conditions.

[0053] It can be understood that the main judgment factors required for changing the vehicle's driving mode include real-time vehicle driving status, current vehicle parameters, driving road conditions and remaining power, for example, the vehicle driving status can be determined based on parameters such as vehicle speed, acceleration, braking force, and whether the driving mode needs to be adjusted. In terms of current vehicle parameters, the vehicle's current power, temperature, humidity, air pressure and other parameters can be obtained to determine whether the vehicle needs to be adjusted. In terms of driving conditions, navigation information, real-time road condition data, etc. can be used to determine the current road conditions and congestion conditions based on the vehicle's location and driving conditions to determine whether the driving mode needs to be adjusted. In terms of remaining power, the vehicle's current power level and the remaining mileage need to be obtained in real time to determine whether adjustments are needed. The application of specific parameters needs to be selected according to actual conditions.

[0054] It should be noted that the current driving state of the vehicle is determined by monitoring the real-time parameters of the vehicle, such as vehicle speed, acceleration, braking force, etc. For example, if the vehicle speed is high and the acceleration is large, it may indicate that the vehicle is in a fast driving state and may need to be adjusted to the sport mode. On the contrary, if the vehicle speed is low and the acceleration is small, it may indicate that the vehicle is in an economic driving state and may need to be adjusted to the economic mode.

[0055] It can be understood that when the remaining power is not enough to support the completion of the remaining mileage, the driving distance should be given priority. Therefore, as long as the mileage that can be traveled by the current battery power is less than the remaining mileage to the destination, the driving mode should be adjusted to the economic mode.

[0056] Step S30: Adjust the throttle pedal curve of the vehicle according to the driving mode, and the vehicle is driven with the throttle pedal curve.

[0057] It can be understood that in the economic mode, the power output and acceleration performance of the vehicle usually decrease relatively to reduce energy consumption and extend the cruising range. The vehicle will limit the maximum power output and adjust the throttle pedal curve to make the response of the throttle pedal smoother, so as to encourage the driver to operate the throttle more gently. On the other hand, the vehicle may optimize the power consumption of the air conditioning system and other auxiliary devices. For example, reduce the operating power of the air conditioner and optimize the energy consumption of seat heating or cooling to reduce the overall energy consumption and battery consumption.

[0058] It can be understood that in the sport mode, the vehicle usually adjusts the power output to provide higher acceleration performance and power response, which may include increasing the maximum power output and optimizing the throttle pedal response curve to make the throttle response more rapid and agile. On the other hand, in the sport mode, the transmission logic of the vehicle may change to adapt to more aggressive driving needs. This may include increasing the shift timing and speed to better utilize the engine performance and keep it matched with the power output.

[0059] It can be understood that in the comfort mode, the throttle pedal curve is usually adjusted to provide a more gentle and smooth acceleration feeling, which means that when the throttle pedal is depressed, the power output will be more smooth and linear to avoid sudden power shocks and overly aggressive acceleration. Specifically, the throttle pedal curve in the comfort mode may adjust the relationship between the movement of the throttle pedal and the power output, and the slope of the curve will be relatively gentle, so that when the throttle is depressed, the increase in power output will be more gradual and linear. The effect of this throttle pedal curve adjustment is to ensure that the driver can more easily control the vehicle acceleration and provide a more stable and predictable power response. This helps to reduce unnecessary shocks or vibrations and provide a more comfortable driving and riding experience.

[0060] In this embodiment, by obtaining the real-time vehicle driving state, including speed, mileage, time, navigation information, etc., to determine the current driving road conditions. According to the driving road conditions and vehicle parameters, such as battery power and navigation information, etc., it can be determined whether it is necessary to adjust the driving mode of the vehicle. According to the determination of the driving mode, the throttle pedal curve can be adjusted accordingly to control the power output and acceleration performance, achieving the flexible selection of a suitable driving mode according to different driving states and requirements to achieve a better driving experience and energy utilization efficiency.

[0061] Refer to Figure 3 , Figure 3 which is a schematic flowchart of the second embodiment of the driving mode adaptive adjustment method of the present invention.

[0062] Based on the above first embodiment, in the driving mode adaptive adjustment method of this embodiment, the step S10 includes:

[0063] Step S101: Obtain the driving mileage within a preset time period at the current moment, and calculate the average speed of the vehicle within this time period.

[0064] It can be understood that taking the current moment as the reference, if the duration of the preset time period is set to one minute, then the driving mileage at this time refers to the driving mileage of the vehicle within one minute before the current moment. The speed result is calculated based on the driving mileage and the duration of the time period, and this is used as the average speed of the vehicle.

[0065] It should be understood that the preset time period should be appropriate, neither too short nor too long. If the time period is too long, the change of the average speed is not timely, and it is easy to have a lag for the vehicle to adjust according to the speed feedback. If the time period is too short, the average speed changes rapidly within a short time, and it is easy for the vehicle to frequently change the driving mode, which will have a certain impact on the performance, safety and lifespan of the vehicle. For example, frequently changing the driving mode may cause the vehicle's components to switch and work more frequently, delivering more energy and heat. This may increase the vehicle's loss, cause the components to wear out or fail faster, and thus shorten the lifespan of the vehicle.

[0066] Step S102: Obtain the navigation information, and confirm the current driving road conditions according to the navigation information and the average speed.

[0067] It should be noted that in practical applications, there are usually some transition sections between congested sections and unobstructed sections. The speed in these transition sections will be between the thresholds of congestion and unobstructed. In these transition sections, the system will not deliberately change the driving mode to avoid frequent mode switching and unnecessary interference. On the contrary, within these transition intervals, the system will maintain the current driving mode until the vehicle enters a clearly congested or unobstructed section.

[0068] It is understandable that in addition to the average speed calculated in real time, navigation information can be introduced to judge the road conditions. Specifically, the navigation information can provide additional information about the road conditions to help judge the current driving road conditions. For example, the navigation system may provide real-time updates on road traffic conditions, accidents, construction, etc. These information can be used in combination with the average speed of the vehicle to more accurately determine the driving road conditions of the current road.

[0069] Furthermore, when the average speed is higher than the first vehicle speed threshold, the preset driving road condition at the current moment is a smooth road condition.

[0070] It is understandable that the average speed here can refer to either the average speed within a period of time or the average speed within a certain mileage. If the average speed exceeds the first vehicle speed threshold, the current road is considered smooth, and the system can accordingly adjust the driving mode of the vehicle to obtain better performance and efficiency.

[0071] Furthermore, when the average speed is lower than the second vehicle speed threshold, the preset driving road condition at the current moment is a congested road condition, and the second vehicle speed threshold is less than the first vehicle speed threshold.

[0072] It is understandable that if the average speed is lower than the second vehicle speed threshold, the road is considered to be in a congested road condition. The second vehicle speed threshold here is a lower speed threshold and should be much lower than the first vehicle speed threshold. This is to distinguish between the two situations of the road being sufficiently congested and sufficiently smooth. Therefore, when the road is identified as a congested road condition, the system will accelerate the response so that the driver can better control the vehicle.

[0073] Furthermore, obtain the navigation information, correct the preset driving road condition according to the navigation information, and use the correction result as the driving road condition at the current moment.

[0074] It is understandable that when judging the current driving road condition, the system can comprehensively consider factors such as navigation information and average speed. If the average speed is higher than the first vehicle speed threshold and the navigation information shows that the road condition is good, then the system can judge that the road is in a smooth road condition. If the average speed is lower than the second vehicle speed threshold and the navigation information shows that there is congestion on the road, then the system can judge that the road is in a congested road condition. If the source of the navigation information is relatively timely and reliable, the road condition information of the navigation information can be used as the judgment result of the road condition information directly.

[0075] In this embodiment, by obtaining the driving mileage at the current moment, calculating the average speed of the vehicle, and combining navigation information to confirm the driving conditions, specifically including determining the approximate road conditions based on the speed thresholds for congestion judgment and the speed thresholds for smooth traffic judgment, and then correcting the recognized road conditions according to the navigation information, the current driving conditions can be judged more accurately, so as to change the throttle pedal curve of the vehicle in the subsequent process, thereby optimizing the driving experience and energy utilization efficiency.

[0076] Refer to Figure 4 , Figure 4 which is a schematic flowchart of the third embodiment of the driving mode adaptive adjustment method of the present invention.

[0077] Based on the above first embodiment, in the driving mode adaptive adjustment method of this embodiment, the step S20 includes:

[0078] Step S201: Obtain the remaining power at the current moment and determine the maximum driving mileage that the remaining power can support.

[0079] It can be understood that the remaining power can be obtained through the battery management system or the display on the electric vehicle dashboard, and the maximum driving mileage that the remaining power can support needs to be calculated based on the remaining power and the energy consumption parameters of the vehicle. The energy consumption parameters of the vehicle can include the efficiency of the motor, the air resistance of the vehicle, the rolling resistance, the energy recovery, etc. By combining the remaining power with the energy consumption parameters, the maximum mileage that the electric vehicle can travel based on the current remaining power can be estimated.

[0080] It should be noted that the energy consumption of the vehicle is a dynamic parameter and will be affected by actual driving conditions, such as driving speed, road conditions, temperature and other factors. Therefore, when calculating, the maximum driving mileage that the remaining power can support can be estimated based on empirical values or historical data. Generally speaking, high-speed driving will result in higher energy utilization efficiency, while low-speed driving has low energy utilization efficiency. That is to say, for the same amount of electricity, the overall mileage is different under different vehicle speeds.

[0081] Step S202: Obtain the remaining mileage of the vehicle to reach the destination at the current moment.

[0082] It can be understood that by using the in-vehicle navigation system, the system can automatically calculate the remaining mileage corresponding to the best route to reach the destination according to factors such as the input destination information, the current vehicle position, and the real-time traffic information.

[0083] Step S203: Based on the remaining power at the current moment, change the driving mode of the vehicle according to the driving conditions and the remaining mileage.

[0084] It is understandable that adjusting the driving mode of the vehicle according to the remaining battery power and driving conditions of the vehicle helps to optimize energy utilization to the greatest extent, extend the driving range, and provide a better driving experience.

[0085] It should be noted that the change of the driving mode can be achieved by controlling the vehicle's power system, throttle response speed, and energy utilization strategy to meet the requirements of energy efficiency and performance under different driving conditions. Specifically, the vehicle's ECU (Electronic Control Unit) is a computer responsible for managing and controlling various systems of the vehicle. Through the vehicle's ECU, the response speed of the throttle pedal input can be adjusted. The ECU can adjust the mapping curve between the throttle pedal input and the engine output to achieve different engine outputs corresponding to different throttle positions. By adjusting the slope and response degree of the mapping curve, the throttle response speed can be changed. On the other hand, after receiving the throttle pedal input, the ECU can output the corresponding command to the engine after a slight delay, which can also change the throttle response speed.

[0086] Furthermore, when the remaining battery power at the current moment is lower than the first battery power threshold, the driving mode of the vehicle is set to the economy mode, and the throttle pedal response speed of the economy mode is slower than that of the comfort mode and the sport mode.

[0087] It is understandable that the throttle pedal response speed of the economy mode is relatively slow to reduce power output, thereby extending the driving range and ensuring that the destination can be safely reached when the battery power is insufficient.

[0088] It should be noted that the original intention of setting the first threshold is mainly to remind the driver that when the battery power drops to a certain level, the driving range of the vehicle may be limited, and at this time, power and power-consuming devices should be used carefully to ensure that the destination can be safely reached or a charging facility can be found. For example, when the first battery power threshold is set to 20%, it can be considered that the battery power is relatively low at this time. In order to complete the mileage, no risky behavior should occur. Therefore, when the first battery power threshold is reached and other factors are not considered, the current driving mode is directly adjusted to the economy mode.

[0089] Furthermore, when the remaining battery power at the current moment is higher than the second battery power threshold and the driving condition is a smooth driving condition, the driving mode of the vehicle is set to the sport mode, and the second battery power threshold is greater than the first battery power threshold.

[0090] It can be understood that when the remaining power is higher than the second power threshold, for example, when the second power threshold is set to 80%, it indicates that the vehicle has sufficient power to support the driving force system to use power and acceleration performance more freely. Therefore, adjusting the driving mode to the sport mode can provide a more aggressive throttle pedal response and power output, providing stronger acceleration performance to meet the needs of the driver for rapid acceleration or overtaking.

[0091] It should be noted that another prerequisite for adjusting the driving mode to the sport mode is that the driving road condition is unobstructed. The driving mode can only be adjusted to the sport mode under unobstructed road conditions. When the two conditions cannot be met simultaneously, it can be considered that the driving mode of the vehicle can be adjusted to the sport mode at this time.

[0092] Furthermore, when the remaining power at the current moment is higher than the second power threshold and the driving road condition is a congested road condition, the driving mode of the vehicle is set to the comfort mode, and the throttle pedal response speed of the comfort mode is slower than that of the sport mode.

[0093] It can be understood that when the driving road condition is congested, the vehicle usually needs to stop frequently and drive slowly, and the opportunities for acceleration and overtaking are relatively few, which will increase the pressure and inconvenience of the driver, because frequent stops and slow driving will prolong the commuting time and increase the waiting and patience of users. In addition, in a crowded road condition, the driver needs to be vigilant at all times, and frequent braking and acceleration may cause fatigue and discomfort. In this case, setting the driving mode to the comfort mode helps to achieve a smoother and more comfortable driving experience.

[0094] It should be noted that the throttle pedal response speed in the comfort mode is relatively slow, making the vehicle's power output more gentle, reducing the overly sensitive response in congested road conditions, helping the driver to better control the vehicle speed, and also reducing energy consumption.

[0095] In this embodiment, by calculating the maximum mileage that the electric vehicle can travel based on the remaining power at the current moment and the energy consumption parameters, and then adjusting the driving mode of the vehicle based on this to meet the user's needs in different situations. When it is congested but the power is sufficient, it is adjusted to the comfort mode to reduce the impact of the congested section on the user experience. When it is unobstructed but the power is sufficient, it is adjusted to the sport mode, and the user can experience a more aggressive driving feeling. When the power is low to the judgment threshold, on the premise of giving priority to reaching the destination, the driving mode of the vehicle is adjusted to the economy mode, adapting to the needs of customers in multiple aspects.
