Description

Technical Field

[0001] The present application relates to the field of vehicle power control, and in particular, to a method, system, device, equipment and medium for coordinating vehicle power control with air conditioning. Background Art

[0002] With the continued growth of vehicle ownership, more and more users are choosing cars as their essential means of transportation. Currently, sudden acceleration to overtake is a common occurrence during driving. However, with users' increasing focus on vehicle dynamics, the responsiveness and dynamics of a vehicle during overtaking have become particularly important. Due to insufficient dynamics, some users' vehicles are unable to quickly increase speed when overtaking, resulting in inability to overtake and even accidents.

[0003] When the driver quickly depresses the accelerator pedal in existing vehicles, such as when overtaking, making an emergency evasive maneuver, or triggering Kick Down mode, the engine / motor needs to output high power instantaneously. The air conditioning system, particularly the electric compressor and PTC heater, can consume 10-30kW of power, resulting in delayed acceleration response and limited peak torque. Furthermore, the larger space in some buses and coaches necessitates the installation of additional compressors or PTCs. This results in significant power consumption by the PTCs and compressors during driving, preventing the vehicle from delivering the required power to the motor, hindering its ability to achieve faster speeds and acceleration.

[0004] Therefore, how to realize the process of coordinated vehicle power control of air conditioning is a technical problem that needs to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0030] First, some of the terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0031] Kick down mode is a forced downshift function in the vehicle's automatic transmission. It is mainly used to increase power output by triggering downshifting by deeply pressing the accelerator during sudden acceleration or overtaking.

[0032] PTC heating element is also called PTC heater, which is composed of PTC ceramic heating element and aluminum tube. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heater. The outstanding feature is safety performance. Under any application, it will not produce the "reddening" phenomenon of the surface of electric heating tube heaters. This application is applied to the scenario of coordinated control of vehicle air conditioning and power. The specific scenario is to adjust the power of the air conditioner according to the vehicle power demand and user demand, and then provide reasonable power for the vehicle power system.

[0033] With the continued growth of vehicle ownership, more and more users are choosing cars as their essential means of transportation. Currently, sudden acceleration to overtake is a common occurrence during driving. However, with users' increasing focus on vehicle dynamics, the responsiveness and dynamics of a vehicle during overtaking have become particularly important. Due to insufficient dynamics, some users' vehicles are unable to quickly increase speed when overtaking, resulting in inability to overtake and even accidents.

[0034] When the driver quickly depresses the accelerator pedal in existing vehicles, such as when overtaking, making an emergency evasive maneuver, or triggering Kick Down mode, the engine / motor needs to output high power instantaneously. The air conditioning system, particularly the electric compressor and PTC heater, can consume 10-30kW of power, resulting in delayed acceleration response and limited peak torque. Furthermore, the larger space in some buses and coaches necessitates the installation of additional compressors or PTCs. This results in significant power consumption by the PTCs and compressors during driving, preventing the vehicle from delivering the required power to the motor, hindering its ability to achieve faster speeds and acceleration.

[0035] To this end, this application switches the vehicle's driving mode based on the brake pedal's opening while the vehicle is in motion. The driving modes include forced downshift and non-forced downshift. When the vehicle is in forced downshift, the air conditioner is controlled to operate in low-power mode. When the vehicle is in non-forced downshift, it identifies whether the road ahead requires acceleration. When acceleration is detected, the air conditioner is controlled to operate in low-power mode. By determining the pedal opening and whether acceleration is required, the air conditioner's power can be controlled to avoid excessive power consumption by accessories when the vehicle needs to accelerate rapidly, limiting the power consumption of accessories. This method enables coordinated vehicle power control of the air conditioner.

[0036] In the embodiment of the present application, the executing entity can be the cooperative vehicle power control air-conditioning equipment in the cooperative vehicle power control air-conditioning system. In actual applications, the cooperative vehicle power control air-conditioning equipment can be electronic devices such as terminal devices and servers, and there is no restriction here.

[0037] The following combination Figure 1 The method of controlling air conditioning in coordination with vehicle power in an embodiment of the present application is described in detail.

[0038] Please see Figure 1 , Figure 1 A flow chart of a method for controlling air conditioning in coordination with vehicle power provided in an embodiment of the present application is shown as follows: Figure 1 The method for controlling air conditioning in coordination with vehicle power includes: Step 110: Switch the vehicle driving mode according to the opening degree of the brake pedal in the vehicle driving state.

[0039] The driving mode includes a forced downshift mode and a non-forced downshift mode.

[0040] In some embodiments of the present application, before switching the vehicle driving mode according to the opening of the brake pedal in the vehicle driving state, Figure 1 The method shown also includes: synchronizing the air conditioning power to the power of the charging pile according to the power of the charging pile in the charging state when the vehicle is not in the driving state.

[0041] In the above process, the present application can directly control the air conditioner through the charging pile when the vehicle is charging, and can provide users with a better air conditioning experience without starting the vehicle.

[0042] Among them, the synchronous air conditioning power is the power of the charging pile, and the vehicle air conditioning can be directly provided with power through the charging pile.

[0043] For example, the vehicle controller determines the vehicle's operating state, such as charging, driving, or stationary. Based on the operating state, the vehicle's energy source is determined. When the vehicle is charging, the vehicle's energy primarily comes from the charging station, ensuring that the power of the vehicle's accessories does not exceed the maximum available power of the charging station.

[0044] In some embodiments of the present application, the vehicle driving mode is switched according to the opening of the brake pedal in the vehicle driving state, including: when the opening of the brake pedal is greater than or equal to the preset opening, the vehicle driving mode is switched to the forced downshift mode; when the opening of the brake pedal is less than the preset opening, the vehicle driving mode is switched to the non-forced downshift mode.

[0045] In the above process, the present application determines the driving mode by the opening degree of the dynamic pedal, and then the air conditioner can be accurately controlled according to the driving mode.

[0046] The preset opening can be set according to demand, such as 95% opening.

[0047] For example, detecting pedal position: The electronic accelerator pedal position sensor converts pedal position information into an electrical signal and transmits it to the vehicle controller. Generally, when the throttle opening is greater than 95% and a downshift is requested, the vehicle controller determines that kickdown (forced downshift mode) may be necessary. However, different vehicle models may set different throttle opening thresholds to trigger the kickdown function based on their design and tuning. Calculating the throttle opening rate of change: The vehicle controller calculates the throttle opening rate of change based on the collected throttle opening signal. When the throttle opening rate of change exceeds the maximum value for the current throttle opening, it indicates that the driver has rapidly stepped on the throttle, generating a downshift acceleration request, which is also a key indicator for determining kickdown. If the accelerator pedal is pressed quickly in a short period of time, resulting in a large opening rate of change, the controller will consider other factors to determine whether to activate the kickdown function. In some embodiments of the present application, after the vehicle driving mode is switched according to the opening of the brake pedal in the vehicle driving state, Figure 1 The method shown further includes: when the opening of the brake pedal is within a preset opening range, controlling the air conditioner to operate at rated power.

[0048] In the above process, the present application can control the power of the air conditioner by setting a preset opening range.

[0049] Among them, the preset opening range and rated power can be one or more, all of which are set according to demand. Different preset opening ranges correspond to a rated power. For example, the rated power is not set for the 0-80% brake pedal opening, and the air conditioning power can be set according to the driving mode and acceleration requirements; a rated power can be set for 80%-90%, 90%-95% and 95%-100% respectively.

[0050] Step 120: When the vehicle driving mode is the forced downshift mode, control the air conditioner to operate in a low power mode.

[0051] Among them, the low-power operation mode can be switched automatically, and the corresponding air-conditioning power is set to a low value. The specific setting value can be set according to needs. The low-power operation mode includes multiple gears, wind speeds, temperature and other parameters. The specific parameter adjustment can be set according to actual needs.

[0052] Step 130: When the vehicle driving mode is the non-forced downshift mode, identify whether there is an acceleration demand on the road ahead.

[0053] In some embodiments of the present application, when the vehicle driving mode is a non-forced downshift mode, identifying whether there is an acceleration demand on the road ahead includes: when the vehicle driving mode is a non-forced downshift mode, a remote sensing image of the road ahead of the vehicle, and determining whether there is an acceleration demand based on the road condition analysis results; or analyzing historical driving data and road acceleration conditions to determine whether there is an acceleration demand on the road ahead.

[0054] During the above process, the present application can determine whether there is a need for acceleration through analysis of remote sensing images or historical data, and then accurately adjust the air conditioner to provide more sufficient power for the vehicle.

[0055] Remote sensing image recognition can be achieved by capturing images of the vehicle ahead while the user is in motion using satellites or radar. Remote sensing images can be identified using an image recognition model to identify road conditions. This model can be trained using historical remote sensing images captured by multiple vehicles while driving. Different road conditions correspond to different acceleration requirements. For example, uphill and straight roads require different acceleration requirements. High-power acceleration is required for uphill driving, while medium-power acceleration is required for straight roads. The air conditioning power should be lower when driving uphill than when driving on straight roads. The specific value can be set based on actual needs.

[0056] For example, when the vehicle is in motion, the vehicle's energy source is the power battery. When the vehicle is in motion, it obtains the accelerator pedal signal collected by the accelerator pedal sensor, analyzes the acceleration demand of historical sections, and uses the collected relevant signals, after processing by the vehicle controller, to indicate the driver's intention and whether there is a need for sudden acceleration. Based on the driver's acceleration demand signal, it is used to indicate the level of vehicle acceleration, such as KickDown or normal overtaking acceleration demand. When the vehicle is in KickDown or sudden acceleration demand, the power of the air conditioner is limited by graded gradient power to give priority to providing reasonable power demand for the vehicle.

[0057] Another example is the calculation of air conditioning power requirements under different operating conditions, with air conditioning power limits applied based on different brake pedal openings. When the accelerator pedal opening is at a low position (defined as a low position requiring vehicle calibration), the vehicle's power consumption is low, and air conditioning power limitation is not required. However, a sudden acceleration request is required. If the driver's intention perception layer identifies a driver acceleration request on the road ahead based on historical data or real-time traffic analysis, components critical to drivability or passenger cabin comfort, such as the battery and heater water temperature, can be pre-cooled or pre-heated. This eliminates the need to use excess power to heat or cool the battery during sudden acceleration. The heater water temperature can also be raised or lowered as much as possible so that the driver doesn't notice the temperature increase due to power limitations when accelerating. If the driver holds the accelerator pedal deeply for an extended period, accessory power can be limited on models with a large number of accessories to ensure the vehicle reaches the design speed, limiting the maximum available air conditioning power.

[0058] Step 140: Identify that there is an acceleration demand on the road ahead and control the air conditioner to operate in low power mode.

[0059] For example, when the vehicle is not charging, the system monitors the brake pedal position while driving. When the vehicle enters KickDown mode, the air conditioner's power is limited to its minimum value for X seconds, then returns to the rated power limit. During power limiting, the compressor takes priority because battery cooling takes precedence. When the vehicle is not in KickDown mode, the system checks the brake pedal position. No power limit is applied between 0-80% (calibration varies for different vehicles). A predictive acceleration algorithm identifies acceleration requirements within X kilometers ahead. If acceleration is detected, the air conditioner temperature is raised or lowered in advance to prevent a rapid decrease or increase in temperature during power limiting. When the brake pedal position is between 90-95%, the system limits the power to X% of the rated value (based on actual vehicle calibration). This reduces the air conditioner's power consumption, resulting in more power available for acceleration, better acceleration performance, and a higher maximum speed. Similarly, at higher brake pedal positions, the air conditioner's power is limited to Y% of the rated value (based on actual vehicle calibration). In the above Figure 1 In the illustrated process, the present application switches the vehicle's driving mode based on the brake pedal's opening while the vehicle is in motion. The driving modes include forced downshift and non-forced downshift. When the vehicle's driving mode is forced downshift, the air conditioner is controlled to operate in low-power mode. When the vehicle's driving mode is non-forced downshift, it identifies whether the road ahead requires acceleration. Upon identifying the need for acceleration, the air conditioner is controlled to operate in low-power mode. By determining the pedal opening and whether acceleration is necessary, the air conditioner's power can be controlled to avoid excessive power consumption by accessories when the vehicle requires rapid acceleration, thereby limiting the power consumption of the accessories. This method enables coordinated vehicle power control of the air conditioner.

[0060] The following combination Figure 2 The system for coordinating vehicle power and controlling air conditioning in an embodiment of the present application is described in detail.

[0061] Please see Figure 2 , Figure 2 A schematic block diagram of a system for coordinating vehicle power control of air conditioning provided in an embodiment of the present application is shown in FIG. Figure 2 The system for collaborative vehicle power control of air conditioning shown includes: a driver intention perception layer, a power demand decision layer, an air conditioning dynamic adjustment layer and a comfort compensation layer; the driver intention perception layer is used to identify the driver's acceleration driving needs under different vehicle operating conditions; the power demand decision layer is used to determine whether to adjust the air conditioning mode and operating power based on the acceleration driving needs and the road conditions ahead; the air conditioning dynamic adjustment layer is used to adjust the air conditioning mode and operating power; the comfort compensation layer is used to analyze historical driving data and navigation data, predict the driver's driving needs, and control the air conditioning power within a preset time in advance.

[0062] The dynamic air conditioning adjustment layer dynamically controls the air conditioning based on the power limits of the power decision layer. This ensures key functions, such as maintaining battery cooling or heating, while also minimizing the impact on the driver during power limits. The comfort compensation layer identifies the driver's acceleration needs based on previous driving or navigation data. Because power limits are higher at larger pedal openings, the air conditioning temperature is pre-emptively raised or lowered by 1-2 degrees Celsius if acceleration is predicted within X kilometers. This prevents drastic cabin temperature fluctuations caused by a significant reduction in air conditioning capacity under larger power limits, ensuring both high-speed and high-responsiveness for the driver and overall comfort.

[0063] Optionally, the system further includes: The vehicle controller includes a processor and a memory, which are used for storing and processing vehicle data respectively.

[0064] Optionally, the system also includes: an acquisition module, which is used to obtain relevant opening and pedaling speed signals collected by the accelerator pedal sensor under different working conditions of the vehicle. The accelerator pedal signal is processed by the acquisition module and used to indicate the driver's demand for acceleration.

[0065] also, Figure 2 The specific methods and steps performed by the system shown can be found in Figure 1 The method shown here will not be described in detail.

[0066] The following combination Figure 3 The implementation method of cooperative vehicle power control air conditioning in an embodiment of the present application is described in detail.

[0067] Please see Figure 3 , Figure 3 A high voltage system framework diagram is provided in an embodiment of the present application, wherein the high voltage system framework executes Figure 1 Methods for controlling air conditioning in coordination with vehicle power, such as Figure 3 The high voltage system block diagram shown includes: Accelerator pedal sensor, VCU, ATC, BMS, DCDC, other controllers, air conditioners, power batteries, DC-DC converters, high-voltage systems, CAN bus and other modules, etc.

[0068] The VCU (Vehicle Control Unit) is a system that uses the accelerator pedal sensor to identify the driver's intention, distribute energy throughout the vehicle, and limit air conditioning power. The ATC (Air Conditioning Controller) automatically adjusts the air conditioning system's cooling, heating, ventilation, and air circulation modes based on feedback from the vehicle's temperature sensor (other sensors may include humidity sensors), maintaining a constant and comfortable temperature inside the vehicle. Dynamic adjustments are also made based on factors such as ambient temperature and sunlight intensity, providing a comfortable interior climate for drivers and passengers. This optimizes energy efficiency, reducing air conditioning system energy consumption to a certain extent, improving vehicle fuel economy and extending the range of new energy vehicles. The BMS (Battery Management System) monitors key battery parameters such as voltage, current, and temperature in real time, accurately estimating the battery's remaining charge (SOC) and state of health (SOH). It also manages battery charge and discharge, optimizes the charging process, prevents abnormalities such as overcharging and over-discharging, balances the performance of individual cells within the battery pack, extends battery life, and ensures safe and stable operation of the battery system. Furthermore, by interacting with other vehicle systems, it enhances the overall performance and user experience of new energy vehicles. The DC-DC converter provides power to the DC-DC converter, converting the DC power from the high-voltage battery system into DC power of varying voltage levels. This provides stable power to multiple low-voltage devices on the vehicle, such as lights, instrument panels, and entertainment systems, ensuring their normal operation. Furthermore, during braking energy recovery, the DC-DC converter converts the electric energy fed back by the motor into a voltage that matches the charging requirements of the power battery, improving energy utilization efficiency and optimizing the battery's charge and discharge processes, extending the power battery's lifespan and ultimately enhancing the overall performance and range of new energy vehicles. These modules can be connected to the high-voltage system via the CAN bus.
