Description

Technical Field

[0001] This application relates to the field of power control technology, specifically to a vehicle power display method, device, and storage medium. Background Technology

[0002] Power output display is a crucial component of the instrument panel display in new energy vehicles, equivalent to the RPM display in traditional gasoline vehicles. It serves as a vital means for users to perceive the vehicle's current driving capability, current regenerative braking capability, and remaining driving and regenerative braking capabilities. Through this display function, users can understand the real-time status of the vehicle's power output and regenerative braking, thereby forming a basic judgment on the vehicle's subsequent power performance and providing important reference for driving operations.

[0003] Currently, power display has become a standard feature in new energy vehicles, and it is often presented as a percentage. This display method compares and converts instantaneous power with peak power to provide users with intuitive numerical feedback on the power status. The operation logic is simple and the presentation effect is direct, so it is widely used in various new energy vehicle models.

[0004] However, this percentage display method often fails to match the user's actual driving experience in real-world driving scenarios. This inconsistency can lead to a cognitive bias in the user's perception of the vehicle's current power level, making it difficult to accurately grasp the vehicle's actual power performance and consequently affecting the judgment and adjustment of driving operations. Summary of the Invention

[0005] In view of this, this application aims to provide a vehicle power display method, device and storage medium that can ensure that the power display information always accurately reflects the actual output capability of the current power system under different operating modes.

[0006] According to a first aspect of this application, a vehicle power display method is provided, comprising: acquiring the instantaneous power output and current operating mode of a target vehicle; the target vehicle being configured with at least two power sources; the current operating mode being used to characterize the operating state of each of the power sources; generating power display information based on the instantaneous power output and the mode peak power in the current operating mode; the power display information being used to compare and display the instantaneous power output and the mode peak power; the mode peak power being the peak power that the target vehicle can output in the current operating mode; and outputting the power display information. Thus, for a target vehicle configured with at least two power sources, power display information is generated based on the instantaneous power output and the mode peak power in the current operating mode to compare and display the instantaneous power output and the mode peak power. This ensures that the power display information always accurately reflects the actual output capability of the current power system under different operating modes, avoiding display deviations caused by using a fixed peak power as a benchmark. This makes the power meter display value highly consistent with the driver's operating intention. In particular, when the accelerator pedal or brake pedal reaches its maximum travel, the power display information can simultaneously reach 100% full scale display, thereby eliminating the user's misunderstanding that the vehicle's performance is limited and improving the user's driving experience.

[0007] Optionally, generating power display information based on the instantaneous power output and the peak power output in the current operating mode includes: acquiring the operating condition information of the target vehicle; the operating condition information representing the current operating condition of the target vehicle; determining the peak power output based on the operating condition information and the current operating mode; and calculating a first ratio of the instantaneous power output to the peak power output to obtain the power display information. This improves the consistency between the power display information and the actual operating state of the vehicle, allowing users to obtain accurate power status feedback under different operating conditions, avoiding display deviations caused by changes in operating conditions from affecting driving judgment, helping to enhance user trust in the power display information, and improving the user's driving experience.

[0008] Optionally, the operating condition information includes the slope information and vehicle speed information of the road where the target vehicle is located; determining the peak power of the mode based on the operating condition information and the current operating mode includes: determining the power reference value corresponding to the current operating mode; determining a first correction coefficient based on the slope information and the vehicle speed information; and correcting the power reference value based on the first correction coefficient to obtain the peak power of the mode. Thus, during driving, uphill and downhill driving will cause changes in the actual power demand at the wheel ends, but the first correction coefficient dynamically compensates for the influence of slope and vehicle speed on the power reference value, ensuring that the corrected power display information accurately reflects the actual available power level under the current operating conditions, eliminating display fluctuations caused by changes in road slope, ensuring the stability and reliability of the power display information under different road conditions, and avoiding misjudgments of the vehicle's power performance by the driver.

[0009] Optionally, generating power display information based on the instantaneous power and the peak power of the current operating mode includes: obtaining a second correction coefficient corresponding to the current operating mode; the second correction coefficient is the ratio of the vehicle peak power to the peak power of the mode; the vehicle peak power is the maximum power output of the target vehicle when all power sources work together; calculating a second ratio of the instantaneous power to the vehicle peak power; and calculating the product of the second ratio and the second correction coefficient to obtain the power display information. By introducing the second correction coefficient, the power display ratio calculated based on the vehicle peak power is corrected, so that the power display information accurately reflects the power output state in the current operating mode. Thus, while maintaining the original calculation logic, power display adaptation between different operating modes can be achieved simply by adjusting the coefficients, with minimal changes and a simple implementation method, thereby facilitating upgrades to existing vehicles.

[0010] Optionally, after outputting the power display information, the method further includes: acquiring the power request information of the target vehicle; determining whether a preset correction condition is met based on the matching degree between the power request information and the power display information; and adjusting the power display information according to the power request information if the preset correction condition is met. When the peak power of the mode is affected, through the above correction mechanism, even if the actual power fluctuates due to environmental factors, the power display information can still match the power request information, avoiding deviations between the display and operational intentions caused by changes in vehicle conditions. This ensures that users can accurately perceive the vehicle's power status based on the display information even under complex environmental conditions, enhancing control over vehicle performance and improving safety and trust during driving.

[0011] Optionally, the power request information includes accelerator pedal opening information and brake pedal opening information; determining whether a preset correction condition is met based on the matching degree between the power request information and the power display information includes: when the target vehicle is in motion and the accelerator pedal opening information or the brake pedal opening information reaches its maximum value, determining whether the preset correction condition is met based on whether the power display information reaches its maximum value. Therefore, by actively correcting potential power display distortion when the power request is strongest or an emergency braking demand occurs, the accuracy and reliability of the display under extreme conditions are significantly improved, ensuring a high degree of consistency between the power display information and the user's actual operating intentions, thereby effectively preventing driving misjudgments and enhancing the user's trust in the display system.

[0012] Optionally, adjusting the power display information based on the power request information includes: adjusting the gradient with a target, and adjusting the power display information based on the power request information; wherein the target adjustment gradient is determined based on the current driving mode and vehicle speed information of the target vehicle. This enables adaptive adjustment of the power display information change rate according to driving mode and vehicle speed information, making the display change rhythm more closely match the rhythm of actual dynamic power response, thus improving the user's driving experience.

[0013] According to a second aspect of this application, a vehicle power display device is provided, comprising: An acquisition module is used to acquire the instantaneous power output and current operating mode of a target vehicle; the target vehicle is equipped with at least two power sources; the current operating mode is used to characterize the operating status of each power source. The generation module is used to generate power display information based on the instantaneous power and the peak power in the current operating mode; the power display information is used to compare and display the instantaneous power and the peak power; the peak power is the peak power that the target vehicle can output in the current operating mode; The output module is used to output the power display information.

[0014] According to a third aspect of this application, an electronic device is provided, comprising: a processor; a memory for storing processor-executable instructions; the processor being configured to perform the method described in any of the above embodiments.

[0015] According to a fourth aspect of this application, a computer-readable storage medium is provided, the storage medium storing a computer program for performing the methods described in any of the above embodiments.

[0016] This application provides a vehicle power display method, device, and storage medium. The solution includes: acquiring the instantaneous power output and current operating mode of a target vehicle; the target vehicle is equipped with at least two power sources; the current operating mode characterizes the operating state of each power source; generating power display information based on the instantaneous power output and the peak power output under the current operating mode; comparing and displaying the instantaneous power output and the peak power output under the current operating mode; the peak power output is the peak power that the target vehicle can output under the current operating mode; and outputting the power display information. This ensures that the power display information accurately reflects the actual output capability of the current power system under different operating modes, avoiding display deviations caused by using a fixed peak power as a benchmark. It also ensures that the power meter display value is highly consistent with the driver's operating intentions, especially when the accelerator or brake pedal reaches its maximum travel, the power display information can simultaneously reach 100% full-scale display, thereby eliminating the user's misunderstanding of limited vehicle performance and improving the user's driving experience.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Application Overview Power display is an important component of the instrument panel display function of new energy vehicles. It is usually presented in the form of energy bar percentage or dial percentage. It is an important way for users to perceive the power output of the vehicle they are driving, and can intuitively reflect the current driving capacity or remaining driving capacity, current recovery capacity or remaining recovery capacity.

[0023] Figure 1 The diagram shown is a schematic representation of a power display provided in one embodiment of this application. Figure 1 As shown, the energy bar on the right displays the current driving power percentage; if the energy bar is on the left, it displays the current braking power; the instantaneous power percentage displays the real-time percentage value of the current driving or energy recovery status in digital form.

[0024] In real-world driving scenarios, the displayed power output often deviates from the user's driving experience. For example, when the vehicle is in pure electric drive mode, the displayed instantaneous drive power never reaches 100% of its full range; similarly, in single-axle energy recovery mode, the power meter's displayed instantaneous regenerative power also fails to reach 100% of its full range. A common user concern is: "Even when the accelerator or brake pedal is fully depressed, the instantaneous drive power or regenerative power display still doesn't reach 100%. Does this mean the vehicle's performance is limited?" Research has revealed that the calculation method for the power display percentage is based on the actual power output at the vehicle's wheel ends as the numerator and the maximum power output of the vehicle's powertrain as the denominator. However, hybrid vehicles' powertrains include multiple modes such as pure electric drive, series, parallel, and power split. The maximum available power output of the powertrain varies significantly across these modes, and the actual power output in some modes cannot reach the maximum available power output corresponding to that mode. Therefore, the power display percentage cannot reach 100%.

[0025] The power display includes two parts: drive power display and braking power display. Drive power display is calculated by using the actual drive power at the vehicle's wheels as the numerator and the maximum drive power of the vehicle's powertrain as the denominator. However, hybrid vehicles' powertrains include various modes such as pure electric drive, series, parallel, and power split. The maximum available drive power varies significantly across these modes, and the actual drive power in some modes may not reach the corresponding maximum available drive power, thus preventing the power display from reaching 100%. Braking power display is calculated by using the actual regenerative braking power at the vehicle's wheels as the numerator and the maximum regenerative power of the vehicle's regenerative braking system under the current operating conditions as the denominator. During braking, there are also various operating modes such as single-axle energy recovery and dual-axle energy recovery, causing the braking power display to typically be less than 100%.

[0026] To address the aforementioned issues, this application embodiment generates power display information based on the instantaneous power output and the peak power output under the current operating mode, comparing and displaying the instantaneous power output with the peak power output under the current operating mode. This significantly improves the matching degree between the power output display and the brake pedal opening and accelerator pedal opening under different operating modes. In particular, when the brake pedal opening and accelerator pedal opening reach 100%, the power output display also reaches its maximum value, achieving a high degree of consistency between the displayed data and the user's driving experience.

[0027] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] Exemplary methods Figure 2 This is a schematic flowchart of a vehicle power display method provided in one embodiment of this application. Figure 2 The method described is performed by the vehicle or a computing device located in the vehicle, but the embodiments of this application are not limited thereto. Figure 2 As shown, the method includes the following: Step S210: Obtain the instantaneous power output and current operating mode of the target vehicle; the target vehicle is equipped with at least two power sources; the current operating mode is used to characterize the operating state of each power source.

[0029] In this embodiment of the application, the target vehicle may be configured with two or more power sources, such as a hybrid vehicle or a pure electric vehicle with two or more electric motors.

[0030] In the embodiments of this application, the power source includes, but is not limited to, an engine, a drive motor, etc.

[0031] In this embodiment, the current operating mode is used to define the operating state of each power source. For hybrid vehicles, the current operating mode may include, but is not limited to, pure electric drive, series, parallel, and power split drive modes, as well as single-axis energy recovery and dual-axis energy recovery modes. For pure electric vehicles, the current operating mode may include single-motor drive mode, dual-motor drive mode, single-motor braking mode, and dual-motor braking mode. The cooperative working method of each power source is different under different operating modes, and each mode corresponds to a specific power source combination and power output logic.

[0032] In this embodiment of the application, the instantaneous power refers to the actual driving power or regenerative power output by the vehicle at the current moment.

[0033] Step S220: Generate power display information based on the instantaneous power and the peak power in the current operating mode; the power display information is used to compare and display the instantaneous power and the peak power; the peak power is the peak power that the target vehicle can output in the current operating mode.

[0034] The peak power of the mode is the maximum drive power or maximum regenerative power that the power system can provide in the current operating mode; the peak power of the mode can be determined based on the available power of the power source and the system control strategy. For example, in series mode, the peak power of the mode can be the rated generating power of the drive motor; in parallel mode, the peak power of the mode can be the sum of the engine direct drive power and the motor drive power. In pure electric mode, the peak power of the mode can be the minimum value between the maximum allowable discharge power of the power battery and the maximum power of the drive motor; in engine direct drive mode, the peak power of the mode can be the maximum output power of the engine.

[0035] In this embodiment of the application, the power display information may be the ratio of instantaneous power to mode peak power, specifically in the form of a percentage value, or an image rendered based on the ratio, such as an energy bar or dial pointer.

[0036] Step S230: Output the power display information.

[0037] In this embodiment of the application, the power display information is output through the vehicle's display terminal, which includes, but is not limited to, the instrument panel, the central control display screen, etc.

[0038] In this embodiment, for a target vehicle equipped with at least two power sources, power display information is generated based on the instantaneous power output and the peak power output in the current operating mode, and the instantaneous power output and peak power output are compared and displayed. This ensures that the power display information accurately reflects the actual output capability of the current power system under different operating modes, avoiding display deviations caused by using a fixed peak power as a benchmark. This ensures that the power meter display value is highly consistent with the driver's operating intentions, especially when the accelerator or brake pedal reaches its maximum travel, the power display information can simultaneously reach 100% full-scale display, thereby eliminating the user's misunderstanding of limited vehicle performance and improving the user's driving experience.

[0039] based on Figure 2 In addition to the method described in the embodiments of this specification, some specific implementation schemes of the method are also provided, which will be described below.

[0040] Optionally, generating power display information based on the instantaneous power and the peak power in the current operating mode includes: Obtain the operating condition information of the target vehicle; the operating condition information is used to represent the current operating condition of the target vehicle; Based on the operating condition information and the current operating mode, determine the peak power of the mode; The power display information is obtained by calculating the first ratio of the instantaneous power to the peak power of the mode.

[0041] In this embodiment, the operating condition information refers to parameter information that affects the peak power of the mode. Specifically, the operating condition information includes environmental information of the environment where the target vehicle is located, and / or, vehicle status information of the target vehicle. The vehicle status information includes vehicle parameters that affect the peak power of the mode, such as engine coolant temperature, battery charge (SOC), and battery state of health (SOH); the environmental information includes environmental parameters that affect the peak power of the mode, such as temperature, humidity, altitude, and road gradient.

[0042] Specifically, for engines, excessively high temperatures can lead to insufficient heat dissipation, potentially triggering thermal protection mechanisms to limit output and reduce peak power. Conversely, excessively low temperatures can affect fuel atomization efficiency or combustion completeness, similarly inhibiting peak power. High humidity increases the water vapor content in the air, potentially altering the intake air-fuel mixture concentration and affecting combustion efficiency, making it difficult for peak power to reach the baseline level for the current operating mode. Increased altitude reduces atmospheric pressure and air density, decreasing engine intake and resulting in insufficient oxygen supply during combustion, causing peak power to decline.

[0043] For electric motors, a low battery SOC directly limits the battery's discharge power, preventing the motor from receiving sufficient energy and thus reducing the peak power of the mode. Low temperatures increase the battery's internal resistance and decrease its discharge efficiency, indirectly affecting the motor's energy input and limiting its peak power. High temperatures trigger the battery's thermal protection mechanism, limiting discharge output to prevent battery damage, which also reduces the motor's peak power. At high altitudes, the reduced air density decreases the motor's air cooling efficiency, leading to temperature accumulation during prolonged operation and triggering the motor's own temperature protection logic, thereby reducing the peak power of the mode accordingly.

[0044] In this embodiment of the application, the peak power of the mode can be determined either by looking up the peak power of the mode based on the operating condition information and the current operating mode, or by calculating the peak power of the mode based on the reference value corresponding to the current operating mode and the correction coefficient determined by the operating condition information.

[0045] In this embodiment of the application, the first correction coefficient can be used to correct the peak power of the mode in combination with the current operating conditions, so that the corrected peak power of the mode is close to the actual maximum available power under the current vehicle conditions.

[0046] In this embodiment, the peak power of the mode is determined based on the operating condition information and the current operating mode, making the peak power of the mode close to the actual maximum usable power under the current vehicle conditions. A first ratio of the instantaneous power to the peak power of the mode is then calculated to obtain the power display information. This improves the consistency between the power display information and the actual operating state of the vehicle, allowing users to obtain accurate power status feedback under different operating conditions. It avoids display deviations caused by changes in operating conditions affecting driving judgment, helps enhance user trust in the power display information, and improves the user's driving experience.

[0047] Optionally, the operating condition information includes the slope information and vehicle speed information of the road where the target vehicle is located; Determining the peak power of the mode based on the operating condition information and the current operating mode includes: Determine the power reference value corresponding to the current operating mode; Based on the slope information and the vehicle speed information, a first correction coefficient is determined; The power reference value is corrected based on the first correction factor to obtain the peak power of the mode.

[0048] In this embodiment, the power reference value is the peak power that the vehicle power system can output under the preset standard slope and standard speed conditions in the current working mode. It is a basic reference value for subsequent correction based on working condition information.

[0049] In this embodiment of the application, the first correction coefficient is a parameter calculated based on the slope information and vehicle speed information. Its value is related to the steepness of the slope and the speed of the vehicle, and is used to quantitatively reflect the degree of influence of the current slope and vehicle speed on the peak power output of the vehicle.

[0050] In this embodiment, a first correction coefficient is determined based on the slope information and the vehicle speed information. The power reference value corresponding to the current operating mode is then corrected based on the first correction coefficient to obtain the power display information. During driving, going uphill or downhill can cause changes in the actual power demand at the wheel ends. However, by dynamically compensating for the influence of slope and vehicle speed on the power reference value through the first correction coefficient, the corrected power display information accurately reflects the actual available power level under the current operating conditions. This eliminates display fluctuations caused by changes in road slope, ensuring the stability and reliability of the power display information under different road conditions and preventing drivers from misjudging the vehicle's power performance.

[0051] Optionally, generating power display information based on the instantaneous power and the peak power in the current operating mode includes: Obtain the second correction coefficient corresponding to the current working mode; the second correction coefficient is the ratio of the vehicle peak power to the mode peak power; the vehicle peak power is the maximum power value that the target vehicle can output when all power sources work together; Calculate the second ratio of the instantaneous power to the vehicle's peak power; The power display information is obtained by calculating the product of the second ratio and the second correction coefficient.

[0052] In this embodiment of the application, the peak power of the vehicle is the maximum power value that the target vehicle can output when all power sources work together.

[0053] In this embodiment of the application, the second ratio is the ratio of instantaneous power to vehicle peak power, which is the power display ratio calculated directly based on vehicle peak power in related technologies.

[0054] In this embodiment of the application, the second correction coefficient can be used to convert the second ratio into power display information that adapts to the current operating mode.

[0055] In this embodiment, by introducing the second correction coefficient, the power display ratio calculated based on the vehicle's peak power is corrected, so that the power display information accurately reflects the power output status under the current operating mode. Therefore, while maintaining the original calculation logic, power display adaptation between different operating modes can be achieved simply by adjusting the coefficient. The modification is minor and the implementation is simple, thus facilitating upgrades to existing vehicles.

[0056] Optionally, after outputting the power display information, the method further includes: Obtain the power request information of the target vehicle; Based on the degree of matching between the power request information and the power display information, determine whether the preset correction conditions are met; If the preset correction conditions are met, the power display information is adjusted according to the power request information.

[0057] In this embodiment of the application, the power request information is used to characterize the intensity of the driver's power demand, such as the accelerator pedal opening, brake pedal opening, etc., and is expressed as a percentage or normalized value.

[0058] In this embodiment, the degree of matching between the power request information and the power display information can be characterized by the difference between the two. Considering the response delay of the vehicle powertrain system, such as engine speed increase and drive motor torque response, if this difference continues to exceed a certain range or fails to converge quickly, it may indicate a mismatch.

[0059] In this embodiment of the application, the preset correction condition may refer to whether the difference between the power request information and the power display information reaches a preset threshold.

[0060] In this embodiment, adjusting the power display information according to the power request information may include adjusting the power display information to match the power request information. For example, when the brake pedal opening is 80%, adjusting the power display information is also used to indicate that the current braking power is close to 80%.

[0061] In practical applications, the peak power of the mode is affected by the vehicle condition. For example, the engine is affected by altitude and engine coolant temperature, the motor is affected by battery temperature, battery charge and battery health, and the fuel cell is affected by ambient temperature.

[0062] In this embodiment of the application, when the peak power of the mode is affected, the above-mentioned correction mechanism ensures that even if the actual power fluctuates due to environmental factors, the power display information can still match the power request information. This avoids the deviation between the display and the operation intention caused by changes in vehicle conditions, and ensures that users can accurately perceive the vehicle's power status based on the display information under complex environmental conditions. This enhances the control over vehicle performance and improves the sense of security and trust during driving.

[0063] Optionally, the power request information includes accelerator pedal opening information and brake pedal opening information; the step of determining whether a preset correction condition is met based on the matching degree between the power request information and the power display information includes: When the target vehicle is in motion and the accelerator pedal opening information or the brake pedal opening information reaches its maximum value, it is determined whether the preset correction condition is met based on whether the power display information reaches its maximum value.

[0064] In this embodiment of the application, the driving state includes the state in which the vehicle is moving forward or backward and the driving speed is not zero.

[0065] In this embodiment of the application, the accelerator pedal opening information is obtained at its maximum value, which means that the accelerator pedal is fully depressed and the opening reaches 100%.

[0066] In this embodiment of the application, the maximum value of the brake pedal opening information refers to the state where the brake pedal is fully depressed and the opening reaches 100%.

[0067] In this embodiment, when the target vehicle is in motion and the accelerator pedal opening information or the brake pedal opening information reaches its maximum value, the power display information should also reach its maximum value. At this time, the user has the strongest operational expectation regarding the vehicle's power output or regenerative braking. If the power display information does not reach its maximum value, the user's perception will be particularly noticeable, requiring a correction mechanism to adjust the display information to match the operational intent.

[0068] In this embodiment, when the target vehicle is in motion and the accelerator pedal opening information or the brake pedal opening information reaches its maximum value, if the power display information does not reach its maximum value, the power display information is adjusted according to the power request information. By actively correcting potential power display distortion when the power request is strongest or an emergency braking demand occurs, the accuracy and reliability of the display under extreme conditions are significantly improved, ensuring a high degree of consistency between the power display information and the user's actual operating intentions. This effectively prevents driving misjudgments and enhances the user's trust in the display system.

[0069] Optionally, adjusting the power display information based on the power request information includes: The target adjustment gradient is used to adjust the power display information according to the power request information; wherein the target adjustment gradient is determined based on the current driving mode and vehicle speed information of the target vehicle.

[0070] In this embodiment of the application, the current driving mode is one of the vehicle's preset operating modes, such as economy mode, snow / mud / sand mode, standard mode, sport mode, etc. Different modes correspond to different power response strategies and output logic.

[0071] In this embodiment, the target adjustment gradient is the magnitude of change per unit time when adjusting the power display information, used to control the adjustment rate of the display information. The target adjustment gradient can be determined jointly by the current driving mode and vehicle speed information.

[0072] In this embodiment, the power response speed varies in different modes. To avoid frequent adjustments that may inconvenience the user, the adjustment process does not directly jump to the display value corresponding to the pedal opening. Instead, the target adjustment gradient is determined based on the power response characteristics of that mode. Generally, the more aggressive the driving mode, the larger the target adjustment gradient. At the same vehicle speed, the target adjustment gradient can increase sequentially from Eco mode, Snow / Sand mode, Standard mode, to Sport mode.

[0073] In this embodiment, the target adjustment gradient differs at different vehicle speeds. Generally, the higher the vehicle speed, the larger the target adjustment gradient. Of course, this does not mean that the gradient and vehicle speed have a strictly linear relationship. For example, by dividing the vehicle speed into intervals, the same target adjustment gradient is used within the same interval, while different intervals correspond to different target adjustment gradients.

[0074] In this embodiment, even if the speed and driving mode are the same under driving and braking conditions, the target adjustment gradient can remain consistent or differ. For example, in the 0-50km / h speed range, the target adjustment gradient under driving conditions can be set to zero. Within this speed range, the accelerator pedal opening is at its maximum, causing the vehicle to accelerate and quickly leave this speed range. At this time, there is no need to change the adjustment rate of the power display information through the target adjustment gradient. However, after the speed exceeds 50km / h, the target adjustment gradient under driving and braking conditions can be unified to the same value.

[0075] In this embodiment, the target adjustment gradient of the power display information is determined based on the current driving mode and vehicle speed information of the target vehicle. This allows for adaptive adjustment of the power display information change rate according to driving mode and vehicle speed information, making the display change rhythm more closely match the actual dynamic power response rhythm, thus improving the user's driving experience.
