Description

Technical Field

[0001] The present invention belongs to the technical field of automobile intelligent control, and specifically relates to a plug-in hybrid vehicle driving mode conversion method and system. Background Art

[0002] In many modern car designs, the driving mode selection function has become one of the key features to enhance driving experience and vehicle performance. This function allows the driver to flexibly adjust the vehicle's driving state according to the current road conditions, driving purpose and personal preferences. Conventional models usually provide three basic driving modes: "Comfort", "Sport" and "Economy".

[0003] Sport mode: Designed to maximize the vehicle's power output, providing the driver with a more aggressive acceleration experience and higher handling responsiveness. This mode is particularly suitable for open, sparsely populated highways or scenarios that require frequent and fast overtaking, and can fully satisfy the driver's pursuit of speed and passion. Economy mode Eco: In this mode, the vehicle system will give priority to energy efficiency, significantly reducing fuel consumption by adjusting engine power output, optimizing shifting logic, and encouraging the use of electric energy (in hybrid or electric vehicles). It is very suitable for long-distance travel, highway cruising, or driving on mountain roads where energy conservation and emission reduction are required, helping drivers achieve more economical driving costs and environmentally friendly travel. Comfort mode Comfort: This mode emphasizes the smoothness of the ride and the ease of driving, and provides passengers with a more quiet and comfortable journey experience by softening the suspension settings, slowing down the throttle response, and reducing engine noise. It is very suitable for daily commuting, family outings, or drivers who have high requirements for driving smoothness.

[0004] However, although these driving modes cover a variety of driving needs, they often ignore the "power mode" selection that is directly related to the power source, that is, the ability to switch between pure electric drive, hybrid drive or pure fuel drive, which is particularly important for new energy vehicles, especially hybrid and electric vehicles.

[0005] Chinese patent CN112644502A proposes a control method for switching driving modes of new energy commercial vehicles. The method defines three basic modes: the pure electric priority ECO mode, the comfortable hybrid Normal mode, and the sporty Sport mode. However, it still does not cover the selection of power modes, that is, it does not fully consider how to intelligently switch between pure electric, hybrid and possible fuel power according to specific driving conditions and driving needs, and the method for adjusting the driving mode is single. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a plug-in hybrid vehicle driving mode conversion method and system, which can allow users to independently select the required driving experience and required energy consumption mode, meet the use of plug-in hybrid vehicles in various driving scenarios, and achieve the purposes of energy saving, comfort and power conservation.

[0007] In order to achieve the above object, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for switching a driving mode of a plug-in hybrid vehicle, comprising the following steps: The information computing center ICC receives a driving mode selection signal; The information computing center ICC sends a corresponding driving mode setting signal to the body domain controller ZCU based on the received driving mode selection signal; The body domain controller ZCU realizes the conversion of driving mode according to the received driving mode setting signal; The driving modes include pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, rain and snow mode, sports mode, extreme pure electric mode and custom mode.

[0008] A further improvement of the present invention is that the driving modes include pure electric priority mode, energy-saving hybrid mode, comfortable hybrid mode, rain and snow mode, sports mode and extreme pure electric mode.

[0009] A further improvement of the present invention is that, in the rain and snow mode, the body domain controller ZCU sends a driving mode setting signal to the intelligent driving computing center ADCC, and the intelligent driving computing center ADCC suppresses the intelligent driving function according to the received setting signal.

[0010] A further improvement of the present invention is that after receiving the driving mode selection signal input by the user, the information computing center ICC sends a corresponding driving mode setting signal to the body domain controller ZCU, and updates the current driving mode on the vehicle information display system according to the driving mode status signal fed back by the body domain controller ZCU.

[0011] A further improvement of the present invention is that after receiving the driving mode setting signal sent by the information computing center ICC, the body domain controller ZCU sends corresponding control signals to the hybrid control unit HCU, the electric power steering module EPS, the automatic suspension control module ASU and the brake controller ONEBOX according to different driving modes, so as to adjust the battery management mode, power mode, steering mode, suspension damping and braking mode.

[0012] A further improvement of the present invention is that the driving mode conversion method also includes realizing the conversion of the driving mode through a hard button on the steering wheel. When the hard button is short pressed, the information computing center ICC switches the driving mode according to a preset cycle sequence. When the hard button is long pressed, the information computing center ICC directly switches to the sports mode.

[0013] A further improvement of the present invention is that the preset cycle order is pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, sports mode, rain and snow mode and custom mode.

[0014] A further improvement of the present invention is that the driving mode conversion method also includes a cold start recovery mode. When the vehicle power state is switched from off to on, if the vehicle is currently in extreme pure electric mode, sports mode or rain and snow mode, the driving mode is automatically converted to pure electric priority mode; if the vehicle is currently in pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode or custom mode, the driving mode is restored to the last memorized driving mode.

[0015] In a second aspect, the present invention further provides a plug-in hybrid vehicle driving mode conversion system, comprising the following modules: A signal receiving module, used for an information computing center ICC to receive a driving mode selection signal; A signal sending module is used for the information computing center ICC to send a corresponding driving mode setting signal to the body domain controller ZCU according to the received driving mode selection signal; The mode conversion module is used by the body domain controller ZCU to realize the conversion of driving mode according to the received driving mode setting signal.

[0016] In a third aspect, the present invention further provides a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the above-mentioned plug-in hybrid vehicle driving mode conversion method when executing the computer program.

[0017] In a fourth aspect, the present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned plug-in hybrid vehicle driving mode conversion method are implemented.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a plug-in hybrid vehicle driving mode conversion method, which provides a variety of driving modes such as pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, rain and snow mode, sports mode, extreme pure electric mode and custom mode, and can meet the personalized needs of different drivers and driving conditions under different road conditions; through the coordinated work of the information computing center ICC, the body domain controller ZCU and various subsystems, intelligent conversion and parameter adjustment of driving modes are realized. This design makes the entire driving mode conversion system highly integrated, and the various components communicate through standardized signals, thereby improving the overall efficiency and reliability of the system; at the same time, the modular design also makes the system easy to maintain and upgrade, reducing the subsequent maintenance costs.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1 As shown, in one embodiment of the present invention, a method for switching driving modes of a plug-in hybrid vehicle is provided, comprising the following steps: S1, the information computing center ICC receives a driving mode selection signal; Table 1 shows the driving scenario modes.

[0028] As shown in Table 1, the driving modes of the present invention include pure electric priority mode, energy-saving hybrid mode, comfortable hybrid mode, rain and snow mode, sports mode, extreme pure electric mode and custom mode. The driving mode can be selected through the large screen or through the hard buttons on the steering wheel. The driving mode is switched by the hard buttons on the steering wheel. When the hard buttons are short pressed, the information computing center ICC switches the driving mode according to a preset cycle sequence. When the hard buttons are long pressed, the information computing center ICC directly switches to the sports mode. The preset cycle sequence is as follows: Figure 2 Shown are pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, sports mode, rain and snow mode and custom mode.

[0029] Compared with the three traditional driving modes, this solution combines the characteristics of plug-in hybrid vehicles (PHEVs) to subdivide the traditional pure electric priority ECO mode into an extreme energy-saving mode, increasing the discharge depth. If the battery level is lower than a lower value, it will be forced to jump back to the pure electric priority ECO mode even when power is fed back.

[0030] Pure electric priority ECO mode, in this mode, pure electric driving is forced. When the battery level is lower than a fixed value (such as the battery level is lower than 13%), the engine is started and the vehicle gives priority to using the battery power. When the battery level is higher than 13%, electric drive is used. When the battery level is lower than 13%, the fuel engine generates electricity and starts. In this mode, the battery management mode enters pure electric priority, the power mode is comfort mode, the steering system enters comfort mode, the suspension mode is comfort mode, and the braking mode is comfort mode. This mode can be used in daily charging conditions when charging conditions are convenient, which ensures driving comfort and reduces fuel consumption and impact on the environment.

[0031] Extreme pure electric mode, this mode needs to be entered under the premise of pure electric priority to maximize the pure electric endurance, but many power-related functions such as acceleration will be restricted. When the power is lower than 8%, it jumps to the pure electric priority mode. In this mode, the power is set to enter the forced electric vehicle EV mode. In this mode, the discharge depth is increased to provide longer pure electric endurance, the power mode enters the economic mode, the steering system enters the comfort mode, the suspension mode is comfort, and the braking mode is comfort.

[0032] Energy-saving hybrid mode, the battery management mode enters fuel priority, the power mode is economic mode, the steering system enters comfort mode, the suspension mode is comfort mode, and the brake mode is comfort mode. This mode gives priority to battery drive, and the engine provides power generation and drive in the most economical state. This mode is suitable for long-distance driving, high-speed or mountain road conditions; Comfort hybrid mode, set the battery management mode to fuel priority, the power mode to comfort mode, the steering system to comfort, the suspension mode to comfort, and the brake mode to comfort. This mode gives priority to battery drive, and the engine intervenes in power generation and driving in a quiet state to improve comfort. The fuel consumption in this mode is relatively high.

[0033] Rain and snow mode, the power mode enters the rain and snow mode, focusing on coping with slippery roads in rainy days, shallow snow, thin snow road conditions and icy road conditions. When encountering slippery icy and snowy road conditions, it can improve grip by reasonably adjusting the front and rear axle torque and power output to ensure that the vehicle does not slip. In addition, the battery management mode will be set to fuel priority, the steering system will enter comfort, the suspension mode will be comfort, the braking mode will be comfort, and the related functions of the intelligent driving itself will be suppressed.

[0034] Sport mode, set the battery management mode to fuel priority, the power mode to sport mode, the steering system to sport, the suspension mode to sport, and the brake mode to sport. In this mode, power is prioritized, and the engine intervenes more actively according to power requirements to provide the vehicle with maximum driving force capability. Compared with other driving mode solutions, this solution provides a strategy of long pressing the MFS driving mode button on the multi-function steering wheel switch to enter the sport mode. Research has found that users like to enter the sport mode on the highway. This design makes it convenient for users to enter the driving mode without operating the display screen.

[0035] Custom mode, battery management mode enters power retention. Compared with common driving modes, this solution provides a way to freely combine driving modes. In this mode, you can freely combine vehicle parameters such as power mode, steering system, suspension damping and brake pedal feel to adjust to the set state. The car's power is maintained at the target power setting SOC value. It is suitable for those who still need to use battery power after using the car or have the need to discharge power for camping. This mode can be used to reserve enough power in advance.

[0036] When the power mode is ON, the user enters the driving settings page and clicks the pure electric priority soft switch. The information computing center ICC sends a driving mode setting signal to the body domain controller ZCU to set it to pure electric priority ECO mode. According to the driving mode status feedback signal pure electric priority returned by the body domain controller ZCU, the system will display that the current driving mode is pure electric priority mode.

[0037] When the power mode is ON, if the information computing center ICC receives a signal from the hybrid control unit HCU that meets the conditions for forced electric vehicle switching, and the user enters the driving settings page and clicks the pure electric priority soft switch, the secondary menu will expand. After the user clicks the extreme pure electric mode switch in the secondary menu, the information computing center ICC will send an extreme pure electric switch signal to the body domain controller ZCU; it will be turned on according to the extreme pure electric state returned by the body domain controller ZCU, and the system will display that the current driving mode is the extreme pure electric mode; if the information computing center ICC receives a signal from the hybrid control unit HCU that does not meet the conditions for forced electric vehicle switching, the extreme pure electric soft switch will turn gray and cannot be operated.

[0038] When the power mode is ON, the user enters the driving setting page and clicks the soft switch of energy-saving hybrid mode, comfort hybrid mode, sports mode or rain and snow mode. The information computing center ICC will send the corresponding driving mode setting signal to the body domain controller ZCU respectively; according to the driving mode status feedback signal returned by the body domain controller ZCU, the system will display the current driving mode as energy-saving hybrid mode, comfort hybrid mode, sports mode or rain and snow mode.

[0039] When the power mode is ON, the user enters the driving setting page and clicks the custom mode soft switch. The information computing center ICC will send a driving mode setting signal to the body domain controller ZCU. According to the driving mode status feedback signal returned by the body domain controller ZCU, the system will display that the current driving mode is the custom mode.

[0040] When selecting Custom mode, users can set the power mode, target battery level, steering mode, suspension mode and braking mode separately: There are four custom power modes: Economy, Comfort, Sport, and Rain and Snow. After selection, the Information Computing Center ICC will send the corresponding custom power mode setting signal to the body domain controller ZCU, and display the power mode status in the current custom setting according to the custom power mode status feedback returned by the body domain controller ZCU; When the information computing center ICC receives the battery management information signal value of maintaining power, the user can set the target battery power SOC in the custom settings, ranging from 30% to 80%. After clicking, the information computing center ICC will send a target battery power setting signal to the body domain controller ZCU. According to the battery power status feedback returned by the body domain controller ZCU, the system will display the current battery power setting information; The customized steering mode has two options: comfort and sport, the suspension mode has two options: comfort and sport, and the braking mode has two options: comfort and sport. After selection, the information computing center ICC will send the corresponding steering mode, suspension mode and braking mode setting signals to the body domain controller ZCU, and display the steering mode, suspension damping and brake pedal feel status in the current customized settings based on the customized steering mode, suspension damping and brake pedal feel status feedback returned by the body domain controller ZCU.

[0041] S2, the information computing center ICC sends a corresponding driving mode setting signal to the body domain controller ZCU according to the received driving mode selection signal; like Figure 3As shown, after receiving the driving mode selection signal input by the user, the information computing center ICC will send a corresponding driving mode setting signal to the body domain controller ZCU, and update the current driving mode on the vehicle information display system according to the driving mode status signal fed back by the body domain controller ZCU.

[0042] When the power mode is ON, the body domain controller ZCU adjusts the vehicle's settings according to the driving mode setting signal sent by the information computing center ICC. The following are the specific adjustments under different driving modes: 1. Pure electric priority ECO mode: After the body domain controller ZCU receives the pure electric priority start signal from the information computing center ICC, it immediately sends a battery management mode setting signal to the hybrid control unit HCU to "ECO"; The hybrid control unit HCU sends a power mode setting signal to "Normal" to ensure that the vehicle operates in normal power mode; The steering system is set to "light" on the electric power steering module EPS, the suspension damping is set to "soft" on the automatic suspension control module ASU, and the brake pedal is set to "comfortable" on the brake controller ONEBOX to improve driving ease and ride comfort; The body domain controller ZCU feeds back the driving mode status as "ECO" to the information computing center ICC, confirming that the current driving mode is the pure electric priority mode.

[0043] 2. Ultimate pure electric mode: After the body domain controller ZCU receives the ultimate pure electric start signal from the information computing center ICC, it forwards it to the hybrid control unit HCU; If the hybrid control unit HCU feeds back a mandatory electric vehicle EV signal, the body domain controller ZCU sets the battery management mode to "ECO" and adjusts the power mode to "ECO", and at the same time adjusts the steering system, suspension damping and brake pedal settings to the same as the pure electric priority mode; If the mandatory electric vehicle (EV) switching conditions are not met, the driving mode will switch to pure electric priority mode and exit the extreme pure electric mode.

[0044] 3. Energy-saving hybrid mode: After the body domain controller ZCU receives the energy-saving hybrid start signal from the information computing center ICC, it sends a battery management mode setting signal to "fuel priority" and a power mode setting signal to "ECO" to the hybrid control unit HCU to achieve energy saving effects; The settings of the steering system, suspension damping and brake pedal are the same as those in the pure electric priority mode; The body domain controller ZCU feeds back the driving mode status as "energy-saving hybrid" to the information computing center ICC.

[0045] 4. Comfort hybrid mode: After the body domain controller ZCU receives the comfort hybrid start signal from the information computing center ICC, the settings of the battery management mode, power mode, steering system, suspension damping and brake pedal are the same as those of the energy-saving hybrid mode, but the power mode is set to "Normal" to provide a more comfortable driving experience; The body domain controller ZCU feeds back the driving mode status as "Normal" to the information computing center ICC.

[0046] 5. Rain and snow mode: After the body domain controller ZCU receives the rain and snow mode start signal from the information computing center ICC, it sends a battery management mode setting signal to the hybrid control unit HCU to set it to "fuel priority" to ensure that the engine can intervene more actively on slippery roads; The power mode is set to "RainSnow", the steering system is set to "Light" to EPS, the suspension damping is set to "Soft" to ASU, and the brake pedal is set to "Comfort" to ONEBOX to improve safety and comfort; The body domain controller ZCU forwards the driving mode setting signal to ADCC to suppress its own intelligent driving function to ensure safe driving of the vehicle in rainy and snowy weather.

[0047] 6. Sports mode: After receiving the sport mode start signal from the information computing center ICC, the body domain controller ZCU sends a battery management mode setting signal to "fuel priority" and a power mode setting signal to "Sport" to the hybrid control unit HCU to provide stronger power output and faster acceleration response; The steering system is set to "Heavy" to EPS, the suspension damping is set to "Hard" to ASU, and the brake pedal is set to "Sport" to ONEBOX to improve handling stability and braking performance; The body domain controller ZCU feeds back the driving mode status as "Sport" to the information computing center ICC.

[0048] In summary, the body domain controller ZCU will adjust the vehicle's battery management, power mode, steering system, suspension damping, brake pedal and other settings according to different driving mode setting signals to ensure the vehicle's performance and comfort in different driving modes.

[0049] When the vehicle is currently in Extreme Pure Electric Mode / Sports Mode / Rain and Snow Mode, if the power status is switched from ON to Off / Comfortable and then to ON, the driving mode will automatically switch to Pure Electric Priority Mode. This is to ensure that after the power is restarted, the vehicle can start and run in the most energy-saving and environmentally friendly way.

[0050] When the vehicle is in pure electric priority mode, energy-saving hybrid mode, comfortable hybrid mode or custom mode, if the power state is switched from ON to Off / Comfortable and then to ON, the vehicle will remember the last vehicle mode and restore it to that mode. This is to provide the driver with a more personalized driving experience and maintain the continuity of the driving mode.

[0051] S3, the body domain controller ZCU realizes the conversion of driving mode according to the received driving mode setting signal; After receiving the driving mode setting signal sent by the information computing center ICC, the body domain controller ZCU sends corresponding control signals to the hybrid control unit HCU, the electric power steering module EPS, the automatic suspension control module ASU and the brake controller ONEBOX according to different driving modes to adjust the battery management mode, power mode, steering mode, suspension damping and braking mode.

[0052] When the hybrid control unit HCU receives the battery management mode setting signal sent by the body domain controller ZCU to pure electric priority and the power mode to comfort hybrid, the hybrid control unit HCU will feedback the battery management information to the information computing center ICC as pure electric priority, and at the same time feedback the current power mode status to the ZCU as "Normal". In addition, the hybrid control unit HCU will control itself to enter the pure electric priority mode.

[0053] The hybrid control unit HCU needs to send a signal to the ICC in real time to indicate whether the conditions for forced electric vehicle EV switching are met.

[0054] When the power mode is ON, when the hybrid control unit HCU receives the "ultimate pure electric" signal sent by the ICC and forwarded by the body domain controller ZCU, the hybrid control unit HCU will feedback the "forced electric vehicle EV signal" to the ICC through the body domain controller ZCU routing.

[0055] When the hybrid control unit HCU receives the battery management mode setting signal as fuel priority and the power mode setting signal as energy-saving hybrid sent by the body domain controller ZCU, the hybrid control unit HCU will feedback the battery management information as fuel priority to the ICC, and at the same time feedback the current power mode status as "ECO" to the body domain controller ZCU; in addition, the hybrid control unit HCU will control itself to enter the energy-saving hybrid mode.

[0058] When the electric power steering module EPS receives the steering system setting signal as light / heavy from the body domain controller ZCU, the electric power steering module EPS adjusts the steering assist to lighter or heavier according to the value of the setting signal.

[0059] When the automatic suspension control module ASU receives the suspension damping setting signal sent by the body domain controller ZCU domain control unit as soft / hard, the automatic suspension control module ASU adjusts the suspension damping according to the value of the setting signal. If the received value is soft, the suspension damping is adjusted to softer; if the received value is hard, the suspension damping is adjusted to harder.

[0060] When the brake controller ONEBOX receives the brake pedal feel (brake system) setting signal of comfort / sport sent by the body domain controller ZCU, the brake controller ONEBOX adjusts the brake pedal feel according to the value of the setting signal. If the signal is comfort, the brake pedal feel will be adjusted to comfort; if the signal is sport, the brake pedal feel will be adjusted to strong.
