Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of intelligent control of automobiles, and particularly relates to a plug-in hybrid automobile driving mode conversion method and system. BACKGROUND

[0002] In many modern car designs, driving mode selection 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 purposes and personal preferences. Conventional models usually provide three basic driving modes: "comfort", "sport" and "economy".

[0003] Sport mode: This mode aims to maximize the vehicle's power output, providing a more aggressive acceleration experience and higher response to the driver's control. It is particularly suitable for open highways with few vehicles or scenes that require frequent and fast overtaking, fully meeting the driver's pursuit of speed and passion. Economy mode: In this mode, the vehicle system prioritizes energy efficiency by adjusting engine power output, optimizing shift logic, and encouraging the use of electric power (in hybrid or electric vehicles), significantly reducing fuel consumption. It is very suitable for long-distance travel, highway cruising or driving on mountain roads that require energy saving and emission reduction, helping the driver achieve more economical driving costs and environmentally friendly travel. Comfort mode: This mode emphasizes smoothness and ease of driving, providing a more peaceful and comfortable travel experience for passengers by softening suspension settings, slowing down 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 overlook the "power mode" selection directly related to the power source, i.e. 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 new energy commercial vehicle driving mode switching, which defines three basic modes: ECO mode for pure electric priority, Normal mode for comfortable hybrid, and Sport mode for sportiness. However, it still does not cover the selection of power mode, i.e. 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 of adjusting the driving mode is single. SUMMARY

[0006] The purpose of the present application is to overcome the above problems, provide a plug-in hybrid vehicle driving mode conversion method and system, which can enable users to autonomously select the required driving experience and the 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 preservation.

[0039] The present application will be described in further detail below in conjunction with the accompanying drawings:

[0040] As shown in the drawings, one embodiment of the present application provides a plug-in hybrid vehicle driving mode conversion method, comprising the following steps: Figure 1

[0041] S1, the information computing center ICC receives the driving mode selection signal;

[0042] Table 1 is a driving scene mode

[0043]

[0044] ​As shown in Table 1, the driving modes of the application include a pure electricity priority mode, an energy-saving hybrid mode, a comfortable hybrid mode, a rain and snow mode, a sports mode, an extreme pure electricity mode and a custom mode, which can be selected by a large screen or by a hard button on a steering wheel. The hard button on the steering wheel is used to switch the driving mode. When the hard button is pressed for a short time, the information computing center ICC switches the driving mode according to a preset cycle sequence. When the hard button is pressed for a long time, the information computing center ICC directly switches to the sports mode. The preset cycle sequence is shown in Table 1 as a pure electricity priority mode, an energy-saving hybrid mode, a comfortable hybrid mode, a sports mode, a rain and snow mode and a custom mode. Figure 2

[0045] Compared with the traditional three driving modes, the application combines the characteristics of a plug-in hybrid electric vehicle PHEV to subdivide a traditional pure electricity priority ECO mode into an extreme energy-saving mode, increase the discharge depth, and forcibly switch back to the pure electricity priority ECO mode if the power is lower than a lower value or even when power feeding.

[0046] The pure electricity priority ECO mode forcibly drives in pure electricity. When the power is lower than a fixed value (such as lower than 13%), the engine is started. The vehicle preferentially uses the battery power. When the power is higher than 13%, the electric power is used for driving. When the power is lower than 13%, the fuel engine generates power and starts. In this mode, the battery management mode enters pure electricity priority, the power mode is comfortable, the steering system enters comfort, the suspension mode is comfortable, and the braking mode is comfortable. This mode can be used in the case of convenient charging conditions, which guarantees the comfort of driving and reduces fuel consumption and the impact on the environment.

[0047] The extreme pure electricity mode needs to be entered on the premise of pure electricity priority to maximize the pure electricity endurance, but many power-related functions such as acceleration will be limited. When the power is lower than 8%, it is switched to the pure electricity priority mode. In this mode, the power is set to enter the forced electric vehicle EV mode. This mode increases the discharge depth to provide longer pure electricity endurance. The power mode enters the economy mode, the steering system enters comfort, the suspension mode is comfortable, and the braking mode is comfortable.

[0048] The energy-saving hybrid mode enters the fuel priority mode, the power mode is the economy mode, the steering system enters comfort, the suspension mode is comfortable, and the braking mode is comfortable. This mode preferentially uses the battery drive, and the engine provides power generation and driving in the most economical state, which is suitable for long-distance driving, high-speed or mountain working conditions.

[0049] ​Comfort hybrid mode, set battery management mode to fuel priority, power mode to comfort mode, steering system to comfort, suspension mode to comfort, brake mode to comfort, this mode preferentially uses battery driving, the engine intervenes in power generation and driving in a quiet state to improve comfort, and the fuel consumption is relatively high.

[0050] Snow mode, power mode enters snow mode, which focuses on dealing with wet and slippery roads in rainy days, shallow snow, thin snow road conditions and icy road conditions, and when encountering wet and slippery icy road conditions, it can improve the grip ability by reasonably adjusting the front and rear axle torque and power output to ensure that the vehicle does not slip, etc., in addition, the battery management mode is set to fuel priority, the steering system enters comfort, the suspension mode is comfort, the brake mode is comfort, and the intelligent driving related functions are inhibited.

[0051] Sport mode, set battery management mode to fuel priority, power mode to sport mode, steering system to sport, suspension mode to sport, brake mode to sport, this mode prioritizes power, the engine intervenes more actively according to power demand to provide maximum driving power for the vehicle; compared with other driving mode schemes, this scheme provides a strategy of entering sport mode by long pressing the multi-function steering wheel switch MFS driving mode key, research finds that users like to enter sport mode at high speed, and this design facilitates users to enter driving mode without operating the display screen.

[0052] Custom mode, battery management mode enters power preservation, compared with common driving modes, this scheme provides a way to freely combine driving modes, in which vehicle parameters such as power mode, steering system, suspension damping and brake pedal feeling adjustment can be freely combined to the set state, the car power is preserved at the target power setting SOC value, which is suitable for using battery power after use or camping power demand, and this mode can be used to reserve enough power in advance.

[0053] When the power mode is ON, the user enters the driving setting page and clicks the pure electric priority soft switch, the information calculation center ICC sends a driving mode setting signal to the vehicle body domain controller ZCU, and sets it to the pure electric priority ECO mode; according to the driving mode state feedback signal pure electric priority returned by the vehicle body domain controller ZCU, the system will display the current driving mode as pure electric priority mode.

[0054] When the power mode is ON, if the information computing center ICC receives a signal from the hybrid control unit HCU that meets the forced electric vehicle switching condition, and the user enters the driving setting page and clicks the pure electric priority soft switch, the secondary menu will be expanded. 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 vehicle body domain controller ZCU. According to the extreme pure electric state start returned by the vehicle body domain controller ZCU, 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 forced electric vehicle switching condition, the extreme pure electric soft switch will become gray and cannot be operated.

[0055] When the power mode is ON, the user enters the driving setting page and clicks the soft switch of the energy-saving hybrid mode, the comfortable hybrid mode, the sports mode, or the rain and snow mode, and the information computing center ICC will send a corresponding driving mode setting signal to the vehicle body domain controller ZCU. According to the driving mode state feedback signal returned by the vehicle body domain controller ZCU, the system will display that the current driving mode is the energy-saving hybrid mode, the comfortable hybrid mode, the sports mode, or the rain and snow mode.

[0056] When the power mode is ON, the user enters the driving setting page and clicks the self-defined mode soft switch, and the information computing center ICC will send a driving mode setting signal to the vehicle body domain controller ZCU. According to the driving mode state feedback signal returned by the vehicle body domain controller ZCU, the system will display that the current driving mode is the self-defined mode.

[0057] When the self-defined mode is selected, the user can set the power mode, target battery capacity, steering mode, suspension mode, and braking mode respectively.

[0058] The self-defined power mode has four options: economy, comfort, sports, and rain and snow. After selection, the information computing center ICC will send a corresponding self-defined power mode setting signal to the vehicle body domain controller ZCU, and according to the self-defined power mode state feedback returned by the vehicle body domain controller ZCU, the system will display the current power mode state in the self-defined setting;

[0059] When the information computing center ICC receives a battery management information signal value of maintaining the capacity, the user can set the target battery capacity SOC in the self-defined setting, with a range of 30% to 80%. After clicking, the information computing center ICC will send a target battery capacity setting signal to the vehicle body domain controller ZCU, and according to the battery capacity state feedback returned by the vehicle body domain controller ZCU, the system will display the current battery capacity setting information;

[0060] The steering mode, suspension mode and brake mode can be set to "Comfort" or "Sport" mode, and after the selection, the information computing center ICC sends the corresponding steering mode, suspension mode and brake mode setting signal to the vehicle body domain controller ZCU, and displays the steering mode, suspension damping and brake pedal feeling state in the current custom settings according to the custom steering mode, suspension damping and brake pedal feeling state feedback returned by the vehicle body domain controller ZCU.

[0061] S2, the information computing center ICC sends the corresponding driving mode setting signal to the vehicle body domain controller ZCU according to the received driving mode selection signal;

[0062] As shown in Figure 3 After receiving the driving mode selection signal input by the user, the information computing center ICC sends the corresponding driving mode setting signal to the vehicle body domain controller ZCU, and updates the current driving mode on the vehicle information display system according to the driving mode state signal feedback by the vehicle body domain controller ZCU.

[0063] When the power mode is ON, the vehicle body domain controller ZCU adjusts the settings of the vehicle according to the driving mode setting signal sent by the information computing center ICC, and the specific adjustment in different driving modes is as follows:

[0064] 1. ECO mode with priority to pure electricity:

[0065] After receiving the pure electricity priority opening signal from the information computing center ICC, the vehicle body domain controller ZCU immediately sends a battery management mode setting signal to the hybrid control unit HCU as "ECO";

[0066] The hybrid control unit HCU sends a power mode setting signal as "Normal" to ensure that the vehicle operates in normal power mode;

[0067] The steering system is set to "light" to the electric power steering module EPS, the suspension damping is set to "soft" to the automatic suspension control module ASU, and the brake pedal is set to "comfort" to the brake controller ONEBOX, so as to improve the ease of driving and riding comfort;

[0068] The vehicle body domain controller ZCU feeds back the driving mode state as "ECO" to the information computing center ICC, confirming that the current driving mode is the pure electricity priority mode.

[0069] 2. Pure electricity mode:

[0070] After receiving the pure electricity opening signal from the information computing center ICC, the vehicle body domain controller ZCU forwards it to the hybrid control unit HCU;

[0071] If the hybrid control unit HCU feedbacks the forced electric vehicle EV signal, the vehicle body domain controller ZCU sets the battery management mode as "ECO" and adjusts the power mode as "ECO", and adjusts the steering system, suspension damping and brake pedal settings as the same as the pure electric priority mode;

[0072] If the forced electric vehicle EV switching condition is not met, the driving mode will switch to the pure electric priority mode and exit the extreme pure electric mode.

[0073] 3. Energy-saving hybrid mode:

[0074] After receiving the energy-saving hybrid opening signal from the information computing center ICC, the vehicle body domain controller ZCU sends the battery management mode setting signal to the hybrid control unit HCU as "fuel priority" and the power mode setting signal as "ECO" to achieve energy-saving effect;

[0075] The settings of the steering system, suspension damping and brake pedal are the same as the pure electric priority mode;

[0076] The vehicle body domain controller ZCU feedbacks the driving mode state as "energy-saving hybrid" to the information computing center ICC.

[0077] 4. Comfortable hybrid mode:

[0078] After receiving the comfortable hybrid opening signal from the information computing center ICC, the vehicle body domain controller ZCU sets the battery management mode, power mode, steering system, suspension damping and brake pedal as the same as the energy-saving hybrid mode, but sets the power mode as "Normal" to provide a more comfortable driving experience;

[0079] The vehicle body domain controller ZCU feedbacks the driving mode state as "Normal" to the information computing center ICC.

[0080] 5. Rain and snow mode:

[0081] After receiving the rain and snow mode opening signal from the information computing center ICC, the vehicle body domain controller ZCU sends the battery management mode setting signal to the hybrid control unit HCU as "fuel priority" to ensure that the engine can intervene more actively on wet and slippery road surface;

[0082] The power mode is set as "RainSnow", the steering system is set as "light" to EPS, the suspension damping is set as "soft" to ASU, and the brake pedal is set as "comfortable" to ONEBOX to improve safety and comfort;

[0083] The vehicle body domain controller ZCU forwards the driving mode setting signal to the ADCC to suppress its own intelligent driving function, ensuring the safe driving of the vehicle in rainy and snowy weather.

[0084] 6. Sports mode:

[0085] Upon receiving the motion mode on signal from the information computing center ICC, the vehicle body domain controller ZCU sends a battery management mode setting signal to the hybrid control unit HCU as "fuel priority" and a power mode setting signal as "Sport" to provide stronger power output and faster acceleration response;

[0086] The steering system is set to "heavy" to the EPS, the suspension damping is set to "hard" to the ASU, and the brake pedal is set to "Sport" to the ONEBOX to improve handling stability and braking performance;

[0087] The vehicle body domain controller ZCU feeds back the driving mode status as "Sport" to the information computing center ICC.

[0088] In summary, the vehicle body domain controller ZCU adjusts the vehicle's battery management, power mode, steering system, suspension damping, and brake pedal settings according to different driving mode setting signals to ensure the vehicle's performance and comfort in different driving modes.

[0089] When the vehicle is currently in the extreme pure electric mode / sport mode / rain and snow mode, if the power state is switched from ON to Off / Comfortable and then to ON, the driving mode will automatically switch to the pure electric priority mode, which is to ensure that after the power is restarted, the vehicle can start and run in the most energy-saving and environmentally friendly way.

[0090] 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 to that mode. This is to provide drivers with a more personalized driving experience and maintain the continuity of the driving mode.

[0091] S3, the vehicle body domain controller ZCU realizes the conversion of the driving mode according to the received driving mode setting signal;

[0092] Upon receiving the driving mode setting signal sent by the information computing center ICC, the vehicle 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 realize the adjustment of the battery management mode, the power mode, the steering mode, the suspension damping, and the brake mode.

[0093] When the hybrid control unit HCU receives the battery management mode setting signal sent by the vehicle body domain controller ZCU as pure electricity priority and the power mode as comfortable hybrid, the hybrid control unit HCU will feedback the battery management information as pure electricity priority to the information calculation center ICC, and feedback the current power mode state as "Normal" to the ZCU, in addition, the hybrid control unit HCU will control itself into the pure electricity priority mode.

[0094] The hybrid control unit HCU needs to send a signal to the ICC in real time whether the forced electric vehicle EV switching condition is met.

[0095] In the state of the power supply mode as ON, when the hybrid control unit HCU receives the "extreme pure electricity" signal sent by the ICC forwarded by the vehicle body domain controller ZCU, the hybrid control unit HCU will feedback the "forced electric vehicle EV signal" to the ICC through the vehicle body domain controller ZCU.

[0096] When the hybrid control unit HCU receives the battery management mode setting signal sent by the vehicle body domain controller ZCU as fuel priority and the power mode setting signal as energy-saving hybrid, the hybrid control unit HCU will feedback the battery management information as fuel priority to the ICC, and feedback the current power mode state as "ECO" to the vehicle body domain controller ZCU; in addition, the hybrid control unit HCU will control itself into the energy-saving hybrid mode.

[0097] When the hybrid control unit HCU receives the battery management mode setting signal sent by the vehicle body domain controller ZCU as fuel priority and the power mode as "Normal", the hybrid control unit HCU will feedback the battery management information as "fuel priority" to the information calculation center ICC, and feedback the current power mode state as "Normal" to the vehicle body domain controller ZCU; in addition, the hybrid control unit HCU will control itself into the comfortable hybrid mode.

[0100] When the hybrid control unit HCU receives the battery management mode setting signal from the vehicle domain controller ZCU as power preservation and the target battery power setting signal after setting, it sends the battery power state feedback signal to the vehicle domain controller ZCU, and sends the battery management information as power preservation to the information calculation center ICC.

[0101] When the electric power steering module EPS receives the steering system setting signal from the vehicle domain controller ZCU as light / heavy, the electric power steering module EPS adjusts the steering assist to be lighter or heavier according to the value of the setting signal.

[0102] When the automatic suspension control module ASU receives the suspension damping setting signal from the vehicle domain controller ZCU 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 be softer, if the received value is hard, the suspension damping is adjusted to be harder.

[0103] When the brake controller ONEBOX receives the brake pedal feel (braking system) setting signal from the vehicle domain controller ZCU as comfortable / sporty, the brake controller ONEBOX adjusts the feeling of the brake pedal according to the value of the setting signal, if the signal is comfortable, the brake pedal feeling is adjusted to be comfortable, if the signal is sporty, the brake pedal feeling is adjusted to be strong.
