Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method and system for controlling vehicle driving modes. Background Technology

[0002] With the development of new energy vehicles, three main types of new energy vehicles have emerged: PHEV (Hybrid Electric Vehicle), BEV (Battery Electric Vehicle), and REEV (Range Extended Electric Vehicle). Different types of new energy vehicles include different driving modes, each corresponding to a different power mode and a battery-saving mode. Therefore, controlling the vehicle's power mode and battery-saving mode according to the driving mode, ensuring that these modes match the vehicle's state under the corresponding driving conditions, is crucial for improving vehicle energy efficiency, optimizing vehicle performance, and ensuring driving safety. Summary of the Invention

[0003] This application provides a method and system for controlling vehicle driving modes, which can be used to improve vehicle energy efficiency, optimize vehicle performance, and ensure driving safety. The technical solution is as follows:

[0004] On one hand, embodiments of this application provide a method for controlling a vehicle driving mode. This method is executed by a vehicle driving mode control system, which includes an ICC (Integrated Adaptive Cruise Control), an FLZCU (Front Left Zone Control Unit), and an HCU (Hybrid Control Unit). The method includes:

[0005] In response to receiving driving mode setting information, the ICC sends the driving mode setting information to the FLZCU;

[0006] In response to receiving the driving mode setting information sent by the ICC, the FLZCU determines the first power mode information and the first power preservation mode information corresponding to the driving mode setting information;

[0007] The FLZCU transmits the first power mode information and the first power preservation mode information to the HCU.

[0008] In response to receiving the first power mode information and the first power-saving mode information, the HCU controls the operation of the vehicle based on the first power mode corresponding to the first power mode information and the first power-saving mode corresponding to the first power-saving mode information, so that the vehicle is in the set driving mode.

[0009] On the other hand, a control system for a vehicle driving mode is provided, the system comprising: ICC, FLZCU and HCU, the system being used to execute the control method for any of the vehicle driving modes described above.

[0010] The technical solution provided in this application brings at least the following beneficial effects:

[0011] In this application, after receiving the driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, facilitating the FLZCU to switch driving modes. Upon receiving the driving mode setting information from the ICC, the FLZCU determines the first power mode information and the first power protection mode information corresponding to the driving mode setting information, thus determining the power mode and power protection mode corresponding to the set driving mode. This facilitates the control of the vehicle's power mode and power protection mode according to the set driving mode. The FLZCU transmits the first power mode information and the first power protection mode information to the HCU.

[0012] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Figure 1 This is a schematic diagram of an implementation environment provided in an embodiment of this application;

[0014] Figure 2 This is a flowchart of a vehicle driving mode control method provided in an embodiment of this application. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0016] This application provides a method for controlling vehicle driving modes. Please refer to... Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: a mobile application (APP) 11, an ICC 12, an FLZCU 13, an HCU (Engine control unit) 14, an ECU 15, a BMS (Battery Management System) 16, a MCU (Motor Control Unit) 17, a center console screen 18, an EPS (Electronic Power Steering) system 19, an ASU (Active Suspension Unit) 20, and an ONEBOX (Hydraulic-by-wire control system) 21.

[0017] Optionally, passengers can set the driving mode via a mobile app 11. The mobile app 11 sends the driving mode setting information to the ICC 12, which then sends the driving mode setting information to the FLZCU 13. The FLZCU 13 determines the first power mode information and the first power-saving mode information corresponding to the driving mode setting information, and then transmits the first power mode information and the first power-saving mode information to the HCU 14. Based on the first power mode information, the HCU 14 controls the internal combustion engine through the ECU 15, controls the power battery through the BMS 16, and controls the electric motor through the MCU 17. Based on the first power mode information, the HCU 14 controls the internal combustion engine through the ECU 15, controls the power battery through the BMS 16, and controls the electric motor through the MCU 17.

[0018] For example, after the vehicle's driving mode is set, HCU14 transmits the driving mode setting completion information to FLZCU13, FLZCU13 forwards the driving mode setting completion information to ICC12, and ICC12 displays the set driving mode through the center console screen 18. The mobile app 11, ICC12, FLZCU13, HCU14, ECU15, BMS16, MCU17, center console screen 18, EPS19, ASU20, and ONEBOX21 establish communication connections via wired or wireless networks.

[0019] Based on the above Figure 1The implementation environment shown in this application provides a method for controlling a vehicle driving mode, such as... Figure 2 As shown, taking the application of this method to a vehicle driving mode control system as an example, the method includes steps 201-204.

[0020] In step 201, in response to receiving driving mode setting information for setting the driving mode, the ICC sends the driving mode setting information to the FLZCU.

[0021] For example, passengers can set the driving mode via a mobile app. The mobile phone used to set the driving mode needs to be connected to the ICC via Bluetooth or connected to the same Wi-Fi network as the ICC. Optionally, after the passenger completes the driving mode setting via the mobile app, the mobile app sends the driving mode setting information to the ICC via Bluetooth or Wi-Fi. Optionally, the driving modes include pure electric priority mode, ultimate pure electric mode, energy-saving hybrid mode, comfort hybrid mode, rain / snow mode, and sport mode.

[0022] For example, in response to receiving driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, including: the ICC sending the driving mode setting information to the FLZCU via a bus, wherein the bus can be a CAN (Controller Area Network) bus. Optionally, the driving mode setting information includes control information on which driving mode the vehicle will switch to.

[0023] In one possible implementation, the user can also click the ICC's driving mode setting switch. In response to the click, the ICC sends the driving mode setting information corresponding to the selected driving mode to the FLZCU. Optionally, different driving mode setting switches correspond to different driving modes, and clicking any driving mode setting switch will complete the setting of the corresponding driving mode. After completing the driving mode setting, the ICC sends the driving mode setting information to the FLZCU.

[0024] In step 202, in response to receiving the driving mode setting information sent by the ICC, the FLZCU determines the first power mode information and the first power preservation mode information corresponding to the driving mode setting information.

[0025] For example, after the ICC sends the driving mode setting information to the FLZCU, in response to receiving the driving mode setting information sent by the ICC, the FLZCU determines the first power mode information and the first battery protection mode information corresponding to the driving mode setting information, including: in response to the driving mode corresponding to the driving mode setting information being a pure electric priority mode, the first power mode information sets the vehicle's power mode to electric mode or hybrid mode, with electric motor drive taking priority, and the first battery protection mode information sets the vehicle's battery protection mode to a first-level battery protection mode; in response to the driving mode setting information being a pure electric mode, the first power mode information sets the vehicle's power mode to electric mode, and the first battery protection mode information sets the vehicle's battery protection mode to a first-level battery protection mode; in response to the driving mode setting information being an energy-saving hybrid mode, a comfort hybrid mode, a rain / snow mode, or a sport mode, the first power mode information sets the vehicle's power mode to hybrid mode, with internal combustion engine drive taking priority, and the first battery protection mode information sets the vehicle's battery protection mode to a second-level battery protection mode, wherein the minimum charge threshold of the power battery in the second-level battery protection mode is less than the minimum charge threshold of the power battery in the first-level battery protection mode.

[0026] In one possible implementation, after the FLZCU receives the driving mode setting information sent by the ICC, if the driving mode corresponding to the driving mode setting information is a pure electric priority mode, then the first power mode corresponding to the first power mode information is determined to be an electric mode or a hybrid mode, with electric motor drive taking priority. Furthermore, the first power preservation mode corresponding to the first power preservation mode information is determined to be a first-level power preservation mode, where the first-level power preservation mode is the vehicle's initial power preservation mode. Optionally, if the control information included in the driving mode setting information specifies which driving mode the vehicle will switch to, then the driving mode corresponding to the driving mode setting information is that driving mode.

[0027] For example, if the driving mode setting information corresponds to the ultimate pure electric mode, then the first power mode corresponding to the first power mode information is determined to be the electric mode. Furthermore, the first power reserve mode corresponding to the first power reserve mode information is determined to be the first-level power reserve mode.

[0028] Optionally, if the driving mode setting information corresponds to an energy-saving hybrid mode, a comfort hybrid mode, a rain / snow mode, or a sport mode, then the first power mode corresponding to the first power mode information is determined to be a hybrid mode. Furthermore, the first power protection mode corresponding to the first power protection mode information is determined to be a secondary power protection mode, wherein the secondary power protection mode is an intelligent power protection mode, and the minimum battery charge threshold in the secondary power protection mode is lower than the minimum battery charge threshold in the primary power protection mode. In one possible implementation, the minimum battery charge threshold in the secondary power protection mode and the minimum battery charge threshold in the primary power protection mode can be set empirically.

[0029] In one possible implementation, if the driving mode setting information corresponds to any one of the following driving modes: pure electric priority mode, ultimate pure electric mode, energy-saving hybrid mode, comfort hybrid mode, or rain / snow mode, then the FLZCU determines the steering system mode, suspension mode, and braking mode as comfort mode. If the driving mode setting information corresponds to the driving mode, then the FLZCU determines the steering system mode, suspension mode, and braking mode as sport mode.

[0030] For example, in Sport mode, the steering system provides a more direct and agile steering response, increasing the driver's sense of control over the vehicle, thus adapting to the needs of Sport mode; in Comfort mode, the steering system provides a lighter steering feel, making driving easier for the driver in non-Sport mode. Optionally, in Sport mode, the suspension is set to be firmer, the shock absorbers respond more quickly, providing more precise handling and reducing body roll, thus adapting to the needs of Sport mode; in Comfort mode, the suspension is softer, absorbing more road vibrations, thus making the driver more comfortable.

[0031] In one possible implementation, the braking mode in Sport mode will be more responsive, with a more direct and rapid braking force output, providing stronger braking power to meet the needs of high-speed driving or emergency braking in Sport mode; the braking mode in Comfort mode will reduce the initial response force of the brake pedal, making the braking process smoother and avoiding driving discomfort caused by excessive braking force.

[0032] In step 203, the FLZCU transmits the first power mode information and the first power-saving mode information to the HCU.

[0033] For example, after determining the first power mode information and the first power-saving mode information, the FLZCU transmits the first power mode information and the first power-saving mode information to the HCU, including: the FLZCU transmits the first power mode information and the first power-saving mode information to the HCU via the CAN bus.

[0034] In one possible implementation, after determining the steering system mode, suspension mode, and braking mode, the FLZCU sends the steering system mode information to the EPS via the CAN bus, the suspension mode information to the ASU via the CAN bus, and the braking mode information to the ONEBOX via the CAN bus.

[0035] In step 204, in response to receiving the first power mode information and the first power protection mode information, the HCU controls the operation of the vehicle based on the first power mode corresponding to the first power mode information and the first power protection mode corresponding to the first power protection mode information, so that the vehicle is in the set driving mode.

[0036] Optionally, after the FLZCU transmits the first power mode information and the first power-saving mode information to the HCU, in response to receiving the first power mode information and the first power-saving mode information, the HCU controls the operation of the vehicle based on the first power mode corresponding to the first power mode information and the first power-saving mode corresponding to the first power-saving mode information. This includes: the HCU controlling the vehicle's power battery, internal combustion engine, and electric motor according to the first power mode corresponding to the first power mode information, so that the vehicle's power mode conforms to the currently set driving mode; and the HCU controlling the vehicle's power battery, internal combustion engine, and electric motor according to the first power-saving mode corresponding to the first power-saving mode information, so that the vehicle's power-saving mode conforms to the currently set driving mode, thereby putting the vehicle in the set driving mode.

[0037] For example, the HCU controls the vehicle's power battery, internal combustion engine, and electric motor according to the first power mode corresponding to the first power mode information, including: the HCU controls the internal combustion engine through the ECU, controls the power battery through the BMS, and controls the electric motor through the MCU according to the first power mode.

[0038] In one possible implementation, the HCU controls the vehicle's power battery, internal combustion engine, and electric motor according to the first power protection mode corresponding to the first power protection mode information. This includes: the HCU controlling the internal combustion engine through the ECU, controlling the power battery through the BMS, and controlling the electric motor through the MCU according to the first power protection mode.

[0039] For example, after setting the vehicle's driving mode, the HCU transmits the driving mode setting completion information to the FLZCU; in response to receiving the driving mode setting completion information, the FLZCU forwards the driving mode setting completion information to the ICC; the ICC displays the driving mode setting completion information. In one possible implementation, after setting the vehicle's driving mode, the HCU transmits the driving mode setting completion information to the FLZCU via the CAN bus, and upon receiving the driving mode setting completion information, the FLZCU forwards the driving mode setting completion information to the ICC via the CAN bus. The ICC displays the driving mode setting completion information after receiving it, including but not limited to: displaying the set driving mode on the vehicle's center console screen.

[0040] For example, if the driving mode is set to pure electric priority mode, when the vehicle is in pure electric priority mode, the HCU obtains a first detection result, which indicates whether the power battery charge is greater than a preset charge. In response to the first detection result indicating that the power battery charge is greater than the preset charge, the HCU sends a signal to the FLZCU allowing switching to the ultimate pure electric mode. In response to receiving the signal from the HCU allowing switching to the ultimate pure electric mode and the setting information of the ultimate pure electric mode sent by the ICC, the FLZCU transmits the second power mode information and the second power reserve mode information corresponding to the ultimate pure electric mode to the HCU. In response to receiving the second power mode information and the second power reserve mode information, the HCU controls the operation of the vehicle based on the second power mode corresponding to the second power mode information and the second power reserve mode corresponding to the second power reserve mode information.

[0041] In one possible implementation, the HCU acquires a first detection result, including: the HCU obtains the power battery's charge level from the BMS via the CAN bus, and then compares the power battery's charge level with a preset charge level. If the power battery's charge level is greater than the preset charge level, the first detection result indicates that the power battery's charge level is greater than the preset charge level; if the power battery's charge level is less than or equal to the preset charge level, the first detection result indicates that the power battery's charge level is less than or equal to the preset charge level.

[0042] For example, after determining that the first detection result indicates that the battery charge is greater than a preset charge, the HCU sends a signal to the FLZCU allowing switching to the ultimate pure electric mode. The FLZCU then sends the signal allowing switching to the ultimate pure electric mode to the ICC. If the first detection result indicates that the battery charge is less than or equal to the preset charge, the HCU sends a signal to the FLZCU disallowing switching to the ultimate pure electric mode. The FLZCU then sends the signal disallowing switching to the ultimate pure electric mode to the ICC. Optionally, in response to receiving a signal allowing switching to the ultimate pure electric mode, the ICC's ultimate pure electric mode setting switch is in a clickable state; in response to receiving a signal disallowing switching to the ultimate pure electric mode, the ICC's ultimate pure electric mode setting switch is grayed out and is in an unclickable state.

[0043] Optionally, passengers can set the ultimate pure electric mode via a mobile app or by clicking the ultimate pure electric mode setting switch. Upon receiving the ultimate pure electric mode setting information, the ICC will send the setting information to the FLZCU.

[0044] For example, in response to receiving a signal from the HCU allowing switching to the ultimate pure electric mode, and the setting information of the ultimate pure electric mode sent by the ICC, the FLZCU transmits the second power mode information and the second power reserve mode information corresponding to the ultimate pure electric mode to the HCU, including: the FLZCU determining the second power mode information and the second power reserve mode information corresponding to the setting information of the ultimate pure electric mode, and the FLZCU transmitting the second power mode information and the second power reserve mode information to the HCU via the CAN bus.

[0045] In one possible implementation, in response to receiving second power mode information and second power-saving mode information, the HCU controls the vehicle's operation based on the second power mode corresponding to the second power mode information and the second power-saving mode corresponding to the second power-saving mode information. This includes: the HCU controlling the vehicle's power battery, internal combustion engine, and electric motor according to the second power mode corresponding to the second power mode information, so that the vehicle's power mode conforms to the ultimate pure electric mode; and controlling the vehicle's power battery, internal combustion engine, and electric motor according to the second power-saving mode corresponding to the second power-saving mode information, so that the vehicle's power-saving mode conforms to the ultimate pure electric mode, thereby putting the vehicle in the ultimate pure electric mode.

[0046] Optionally, after the vehicle is in the ultimate pure electric mode, the HCU continuously acquires the first detection result; in response to the first detection result indicating that the power battery charge is less than or equal to the preset charge, the HCU sends a signal to the FLZCU that the ultimate pure electric mode is not met; in response to receiving the signal that the ultimate pure electric mode is not met, the FLZCU transmits the third power mode information and the third power reserve mode information corresponding to the pure electric priority mode to the HCU; in response to receiving the third power mode information and the third power reserve mode information, the HCU controls the operation of the vehicle based on the third power mode corresponding to the third power mode information and the third power reserve mode corresponding to the third power reserve mode information.

[0047] For example, after the vehicle enters the ultimate pure electric mode, the HCU continuously obtains the battery charge level through the BMS. If the first detection result indicates that the battery charge level is less than or equal to a preset charge level, the HCU sends a signal to the FLZCU that switching to the ultimate pure electric mode is not allowed. Optionally, in response to receiving a signal that the ultimate pure electric mode is not satisfied, the FLZCU transmits the third power mode information and the third power reserve mode information corresponding to the pure electric priority mode to the HCU, including: the FLZCU determining the third power mode information and the third power reserve mode information corresponding to the pure electric priority mode setting information, and the FLZCU transmitting the third power mode information and the third power reserve mode information to the HCU via the CAN bus.

[0048] In one possible implementation, in response to receiving third power mode information and third power-saving mode information, the HCU controls the vehicle's operation based on the third power mode corresponding to the third power mode information and the third power-saving mode corresponding to the third power-saving mode information. This includes: the HCU controlling the vehicle's power battery, internal combustion engine, and electric motor according to the third power mode corresponding to the third power mode information, so that the vehicle's power mode conforms to the pure electric priority mode; and controlling the vehicle's power battery, internal combustion engine, and electric motor according to the third power-saving mode corresponding to the third power-saving mode information, so that the vehicle's power-saving mode conforms to the pure electric priority mode, thereby putting the vehicle in the pure electric priority mode.

[0049] For example, when the driving mode is pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, rain / snow mode or sport mode, in response to the vehicle's power state being turned off and then on again, the vehicle's driving state when the power state is turned on again is pure electric priority mode; when the driving mode is ultimate pure electric mode, in response to the vehicle's power state being turned off and then on again, the vehicle's driving state when the power state is turned on again is ultimate pure electric mode.

[0050] In one possible implementation, when the driving mode is set to pure electric priority mode, energy-saving hybrid mode, comfort hybrid mode, rain / snow mode, or sport mode, if the vehicle's power is turned off and then on again, the default driving mode will be set to pure electric priority mode. Similarly, when the driving mode is set to ultimate pure electric mode, if the vehicle's power is turned off and then on again, the default driving mode will be set to ultimate pure electric mode.

[0051] Optionally, the target battery charge level can also be set via a mobile app. For example, setting the target battery charge level includes: in response to receiving target battery charge level setting information, the ICC sends the target battery charge level setting information to the FLZCU; in response to receiving the target battery charge level setting information, the FLZCU forwards the target battery charge level setting information to the HCU; and in response to receiving the target battery charge level setting information, the HCU controls the vehicle's battery charge level to remain within the preset range of the target battery charge level.

[0052] In one possible implementation, after the passenger sets the target battery charge level via a mobile app, the app sends the target charge level information to the ICC (Integrated Circuit Control Center) via Bluetooth or a wireless network. Upon receiving the target charge level setting information, the ICC transmits it to the FLZCU (Fuel Cell Control Unit) via the CAN bus. The FLZCU then forwards the target charge level setting information to the HCU (Hardware Control Unit) via the CAN bus. Upon receiving the target charge level setting information, the HCU uses the BMS (Battery Management System) to maintain the vehicle's battery charge level within the preset target range. Optionally, the preset range can be set based on experience.

[0053] For example, after the HCU controls the power battery of the vehicle to maintain the power battery charge within a preset range of the target power battery charge, in response to the power battery charge exceeding the preset range of the target power battery charge, the HCU transmits the information that the power battery charge exceeds the preset range of the target power battery charge to the FLZCU; in response to receiving the information that the power battery charge exceeds the preset range of the target power battery charge, the FLZCU forwards the information that the power battery charge exceeds the preset range of the target power battery charge to the ICC; the ICC displays the information that the power battery charge exceeds the preset range of the target power battery charge.

[0054] Optionally, after setting the target battery level, the HCU continuously monitors the battery level via the BMS. If the battery level exceeds the preset range of the target battery level, the HCU transmits this information to the FLZCU via the CAN bus. Upon receiving this information, the FLZCU forwards it to the ICC via the CAN bus. The ICC then displays this information via various means, including but not limited to displaying it on the vehicle's center console screen.

[0055] In one possible implementation, passengers can also set personalized driving modes via a mobile app. For example, passengers can manually set the power mode to hybrid mode and the battery protection mode to forced battery protection mode. Upon receiving personalized driving mode setting information, the ICC sends the personalized driving mode setting information to the FLZCU; upon receiving the personalized driving mode setting information, the FLZCU determines the fourth power mode information and the fourth battery protection mode information corresponding to the personalized driving mode setting information; the FLZCU transmits the fourth power mode information and the fourth battery protection mode information to the HCU; upon receiving the first power mode information and the fourth battery protection mode information, the HCU controls the vehicle's operation based on the fourth power mode corresponding to the fourth power mode information and the fourth battery protection mode corresponding to the fourth battery protection mode information, thus putting the vehicle in personalized driving mode. In the forced battery protection mode, the minimum battery charge threshold is lower than the minimum battery charge threshold in the secondary battery protection mode.

[0056] In this embodiment, after receiving the driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, facilitating the FLZCU to switch driving modes. Upon receiving the driving mode setting information from the ICC, the FLZCU determines the first power mode information and the first power reserve mode information corresponding to the driving mode setting information, thus determining the power mode and power reserve mode corresponding to the set driving mode. This facilitates the control of the vehicle's power mode and power reserve mode according to the set driving mode. The FLZCU transmits the first power mode information and the first power reserve mode information to the HCU. In response to receiving the first power mode information and the first power reserve mode information, the HCU controls the vehicle's operation based on the first power mode and the first power reserve mode information, thereby placing the vehicle in the set driving mode. This achieves control of the vehicle's power mode and power reserve mode according to the set driving mode, ensuring that the vehicle's power mode and power reserve mode meet the required state under the set driving mode, improving vehicle energy efficiency, optimizing vehicle performance, and enhancing driving safety.
