[0013] FIG. 2 is a flowchart of a control method for vehicle driving mode provided by an embodiment of the present application. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0015] Embodiments of the present application provide a vehicle driving mode control method. Please refer to FIG. 1, which shows a schematic diagram of a method implementation environment provided by embodiments of the present application. The implementation environment can include a mobile phone APP (Application) 11, an ICC 12, an FLZCU 13, an HCU (Engine control unit) 14, an ECU 15, a BMS (Battery Management System) 16, an MCU (Motor Control Unit) 17, a screen of a center console 18, an EPS (Electronic Power Steering) 19, an ASU (Active Suspension Unit) 20, and an ONEBOX (line control hydraulic control system) 21.

[0016] Optionally, a passenger can set a driving mode through the mobile phone APP 11. The mobile phone APP 11 sends driving mode setting information to the ICC 12, and the ICC 12 sends the driving mode setting information to the FLZCU 13. The driving mode setting information is used to set the driving mode. The FLZCU 13 determines first power mode information and 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. The HCU 14 controls an internal combustion engine through the ECU 15, controls a power battery through the BMS 16, and controls an electric motor through the MCU 17 based on a first power mode corresponding to 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 a first power saving mode corresponding to the first power saving mode information.

[0017] For example, after the setting of the driving mode of the vehicle is completed, the HCU 14 transmits first information to the FLZCU 13, the FLZCU 13 forwards the first information to the ICC 12, and the ICC 12 displays the first information on the screen 18 of the center console. The first information is information indicating that the setting of the driving mode is completed. The mobile phone APP 11, the ICC 12, the FLZCU 13, the HCU 14, the ECU 15, the BMS 16, the MCU 17, the screen 18 of the center console, the EPS 19, the ASU 20, and the ONEBOX 21 are communicatively connected through a wired or wireless network.

[0018] Based on the implementation environment shown in FIG. 1, embodiments of the present application provide a vehicle driving mode control method as shown in FIG. 2. Taking the method applied to a vehicle driving mode control system as an example, the method includes steps 201-204.

[0019] In step 201, in response to receiving the driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, the driving mode setting information being used for setting the driving mode.

[0020] For example, the passenger can set the driving mode through a mobile phone APP, wherein the mobile phone used for setting the driving mode needs to be connected with the ICC, or connected to the same wireless network as the ICC, and the mobile phone used for setting the driving mode is connected with the ICC through Bluetooth. Alternatively, after the setting of the driving mode is completed, the mobile phone APP sends the driving mode setting information to the ICC through Bluetooth or a wireless network, the driving mode setting information being used for setting the driving mode. Alternatively, the driving mode includes a pure electric priority mode, an extreme pure electric mode, an energy-saving hybrid mode, a comfortable hybrid mode, a rain and snow mode, and a sports mode.

[0021] For example, in response to receiving the driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, including: the ICC sends the driving mode setting information to the FLZCU through a bus, wherein the bus can be a CAN (Controller Area Network) bus. Alternatively, the driving mode setting information contains control information of the driving mode to be switched by the vehicle.

[0022] In a possible implementation, the user can also click the driving mode setting switch of the ICC, and in response to the driving mode switch of the ICC being clicked, the ICC sends the driving mode setting information corresponding to the driving mode switch to the FLZCU. Alternatively, different driving mode setting switches correspond to different driving mode setting information, and clicking any driving mode setting switch can complete the setting of the corresponding driving mode. After the setting of the driving mode is completed, the ICC sends the driving mode setting information to the FLZCU.

[0023] In step 202, in response to receiving the driving mode setting information, the FLZCU determines first power mode information and first power saving mode information corresponding to the driving mode setting information, the driving mode setting information being sent by the ICC.

[0024] Exemplarily, 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 power saving mode information corresponding to the driving mode setting information, including: in response to the driving mode corresponding to the driving mode setting information being the pure electric priority mode, determining that the first power mode information is to set the power mode of the vehicle to the electric mode or the hybrid mode, and the electric motor driving priority, and the first power saving mode information is to set the power saving mode of the vehicle to the first level power saving mode; in response to the driving mode corresponding to the driving mode setting information being the extreme pure electric mode, determining that the first power mode information is to set the power mode of the vehicle to the electric mode, and the first power saving mode information is to set the power saving mode of the vehicle to the first level power saving mode; in response to the driving mode corresponding to the driving mode setting information being the energy saving hybrid mode, the comfortable hybrid mode, the rain and snow mode or the sports mode, determining that the first power mode information is to set the power mode of the vehicle to the hybrid mode, and the internal combustion engine driving priority, and the first power saving mode information is to set the power saving mode of the vehicle to the second level power saving mode, and the minimum power threshold of the power battery in the second level power saving mode is less than the minimum power threshold of the power battery in the first level power saving mode.

[0025] In a 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 the pure electric priority mode, it is determined that the first power mode corresponding to the first power mode information is the electric mode or the hybrid mode, and the electric motor driving priority. And it is determined that the first power saving mode corresponding to the first power saving mode information is the first level power saving mode, wherein the first level power saving mode is the initial power saving mode of the vehicle. Optionally, the control information contained in the driving mode setting information is to switch the driving mode of the vehicle to which driving mode, and the driving mode corresponding to the driving mode setting information is the driving mode.

[0026] Exemplarily, if the driving mode corresponding to the driving mode setting information is the extreme pure electric mode, it is determined that the first power mode corresponding to the first power mode information is the electric mode. And it is determined that the first power saving mode corresponding to the first power saving mode information is the first level power saving mode.

[0027] Optionally, if the driving mode corresponding to the driving mode setting information is the energy saving hybrid mode, the comfortable hybrid mode, the rain and snow mode or the sports mode, it is determined that the first power mode corresponding to the first power mode information is the hybrid mode. And it is determined that the first power saving mode corresponding to the first power saving mode information is the second level power saving mode, wherein the second level power saving mode is the intelligent power saving mode, and the minimum power threshold of the power battery in the second level power saving mode is less than the minimum power threshold of the power battery in the first level power saving mode. In a possible implementation, the minimum power threshold of the power battery in the second level power saving mode and the minimum power threshold of the power battery in the first level power saving mode can be set according to experience.

[0028] In a possible implementation, if the driving mode corresponding to the driving mode setting information is any one of the pure-electric priority mode, the pure-electric extreme mode, the energy-saving hybrid mode, the comfortable hybrid mode, or the rain and snow mode, the FLZCU determines that the mode of the steering system is the comfortable mode, the suspension mode is the comfortable mode, and the brake mode is the comfortable mode. If the driving mode corresponding to the driving mode setting information is the sports mode, the FLZCU determines that the mode of the steering system is the sports mode, the suspension mode is the sports mode, and the brake mode is the sports mode.

[0029] For example, the steering system in the sports mode provides more direct and agile steering response, increases the driver's control of the vehicle, and thus meets the requirements of the sports mode; the steering system in the comfortable mode provides a lighter steering feel, and thus makes the driver more relaxed when driving in the non-sports mode. Alternatively, the suspension mode in the sports mode is set to be more rigid, the shock absorber responds more quickly, provides more accurate control, and reduces body roll, and thus meets the requirements of the sports mode; the suspension mode in the comfortable mode is softer, and absorbs more road vibrations, and thus makes the driver more comfortable.

[0030] In a possible implementation, the brake mode in the sports mode responds more sensitively, and the braking force is output more directly and quickly, and can provide stronger braking force, and thus meets the requirements of high-speed driving or emergency braking in the sports mode; the brake mode in the comfortable mode reduces the initial response of the brake pedal, and makes the braking process more gentle, and avoids the discomfort caused by the excessive braking force.

[0031] In step 203, the FLZCU transmits the first power mode information and the first power preservation mode information to the HCU.

[0032] For example, after determining the first power mode information and the first power preservation mode information, the FLZCU transmits the first power mode information and the first power preservation mode information to the HCU, including: the FLZCU transmits the first power mode information and the first power preservation mode information to the HCU through the CAN bus.

[0033] In a possible implementation, after determining the mode of the steering system, the suspension mode, and the brake mode, the FLZCU sends the mode information of the steering system to the EPS through the CAN bus, sends the suspension mode information to the ASU through the CAN bus, and sends the brake mode information to the ONEBOX through the CAN bus.

[0034] In step 204, in response to receiving the first power mode information and the first power conservation 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 conservation mode corresponding to the first power conservation mode information, so that the vehicle is in the set driving mode.

[0035] Optionally, after the FLZCU transmits the first power mode information and the first power conservation mode information to the HCU, in response to receiving the first power mode information and the first power conservation 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 conservation mode corresponding to the first power conservation mode information, including: the HCU controls the power battery, the internal combustion engine and the motor of the vehicle according to the first power mode corresponding to the first power mode information, so that the power mode of the vehicle conforms to the currently set driving mode; the HCU controls the power battery, the internal combustion engine and the motor of the vehicle according to the first power conservation mode corresponding to the first power conservation mode information, so that the power conservation mode of the vehicle conforms to the currently set driving mode, so that the vehicle is in the set driving mode.

[0036] Illustratively, the HCU controls the power battery, the internal combustion engine and the motor of the vehicle 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 motor through the MCU according to the first power mode.

[0037] In a possible implementation, the HCU controls the power battery, the internal combustion engine and the motor of the vehicle according to the first power conservation mode corresponding to the first power conservation mode information, including: the HCU controls the internal combustion engine through the ECU, controls the power battery through the BMS, and controls the motor through the MCU according to the first power conservation mode.

[0038] Illustratively, after the setting of the driving mode of the vehicle is completed, the HCU transmits first information to the FLZCU, the first information being information that the setting of the driving mode is completed; in response to receiving the first information, the FLZCU forwards the first information to the ICC; the ICC displays the first information.

[0039] In a possible implementation, after the setting of the driving mode of the vehicle is completed, the HCU transmits the first information to the FLZCU through the CAN bus, and after receiving the first information, the FLZCU forwards the first information to the ICC through the CAN bus. After receiving the first information, the ICC displays the first information in the following manner, including but not limited to: displaying the set driving mode through the screen of the vehicle center console.

[0040] Exemplarily, if the set driving mode is the pure electric priority mode, the HCU acquires a first detection result in a case where the vehicle is in the pure electric priority mode, the first detection result being used to indicate whether the power amount of the power battery is greater than the electric amount; in response to the first detection result indicating that the power amount of the power battery is greater than the electric amount, the HCU sends a first signal to the FLZCU, the first signal being a signal allowing switching to the extreme pure electric mode; in response to receiving the first signal and setting information of the extreme pure electric mode, the FLZCU transmits second power mode information and second power conservation mode information corresponding to the extreme pure electric mode to the HCU, the setting information of the extreme pure electric mode being sent by the ICC; in response to receiving the second power mode information and the second power conservation mode information, the HCU controls the operation of the vehicle based on a second power mode corresponding to the second power mode information and a second power conservation mode corresponding to the second power conservation mode information.

[0041] Optionally, the HCU acquires the first detection result, including: the HCU acquires the power amount of the power battery from the BMS through the CAN bus, and then compares the power amount of the power battery with the electric amount. If the power amount of the power battery is greater than the electric amount, the first detection result indicates that the power amount of the power battery is greater than the electric amount; if the power amount of the power battery is less than or equal to the electric amount, the first detection result indicates that the power amount of the power battery is less than or equal to the electric amount.

[0042] In a possible implementation, after determining that the first detection result indicates that the power amount of the power battery is greater than the electric amount, the HCU sends a first signal to the FLZCU, and the FLZCU sends the first signal to the ICC. After receiving the first signal, the extreme pure electric mode setting switch of the ICC is in a state that can be clicked.

[0043] Exemplarily, if the first detection result indicates that the power amount of the power battery is less than or equal to the preset electric amount, the HCU sends a second signal to the FLZCU, the second signal being a signal that does not satisfy the extreme pure electric mode. The FLZCU sends the second signal to the ICC. Optionally, after receiving the second signal, the extreme pure electric mode setting switch of the ICC is grayed out, that is, in a state that cannot be clicked.

[0044] Optionally, the passenger can set the extreme pure electric mode by clicking the extreme pure electric mode setting switch, and can also set the extreme pure electric mode through a mobile phone APP. In response to receiving the setting information of the extreme pure electric mode, the ICC sends the setting information of the extreme pure electric mode to the FLZCU.

[0045] Exemplarily, in response to receiving the first signal and the setting information of the pure electric mode, the FLZCU transmits second power mode information and second power conservation mode information corresponding to the pure electric mode to the HCU, including: the FLZCU determining the second power mode information and the second power conservation mode information corresponding to the setting information of the pure electric mode, and the FLZCU transmitting the second power mode information and the second power conservation mode information to the HCU through the CAN bus.

[0046] In a possible implementation, in response to receiving the second power mode information and the second power conservation mode information, the HCU controls the operation of the vehicle based on a second power mode corresponding to the second power mode information and a second power conservation mode corresponding to the second power conservation mode information, including: the HCU controlling the power battery, the internal combustion engine and the motor of the vehicle according to the second power mode corresponding to the second power mode information, so that the power mode of the vehicle conforms to the pure electric mode; and the HCU controlling the power battery, the internal combustion engine and the motor of the vehicle according to the second power conservation mode corresponding to the second power conservation mode information, so that the power conservation mode of the vehicle conforms to the pure electric mode, thereby making the vehicle in the pure electric mode.

[0047] Optionally, after the vehicle is in the pure electric mode, the HCU continuously acquires the first detection result; in response to the first detection result indicating that the power of the power battery is less than or equal to the power, the HCU sends a second signal to the FLZCU; in response to receiving the second signal, the FLZCU transmits third power mode information and third power conservation mode information corresponding to the pure electric priority mode to the HCU; and in response to receiving the third power mode information and the third power conservation mode information, the HCU controls the operation of the vehicle based on a third power mode corresponding to the third power mode information and a third power conservation mode corresponding to the third power conservation mode information.

[0048] Exemplarily, after the vehicle is in the pure electric mode, the HCU continuously acquires the power of the power battery through the BMS, and if the first detection result indicates that the power of the power battery is less than or equal to the power, the HCU sends a second signal to the FLZCU. Optionally, in response to receiving the second signal, the FLZCU transmits third power mode information and third power conservation 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 conservation mode information corresponding to the setting information of the pure electric priority mode, and the FLZCU transmitting the third power mode information and the third power conservation mode information to the HCU through the CAN bus.

[0049] In a possible implementation, in response to receiving the third power mode information and the third power conservation 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 conservation mode corresponding to the third power conservation mode information, including: the HCU controls the power battery, the internal combustion engine and the motor of the vehicle according to the third power mode corresponding to the third power mode information, so that the power mode of the vehicle conforms to the pure electric priority mode; and controls the power battery, the internal combustion engine and the motor of the vehicle according to the third power conservation mode corresponding to the third power conservation mode information, so that the power conservation mode of the vehicle conforms to the pure electric priority mode, so that the vehicle is in the pure electric priority mode.

[0050] For example, when the driving mode is the pure electric priority mode, the energy-saving hybrid mode, the comfortable hybrid mode, the rain and snow mode or the sports mode, in response to the power supply state of the vehicle being turned off and then turned on again, the driving state of the vehicle is set to the pure electric priority mode when the power supply state is turned on again; when the driving mode is the pure electric priority mode, in response to the power supply state of the vehicle being turned off and then turned on again, the driving state of the vehicle is set to the pure electric priority mode when the power supply state is turned on again.

[0051] In a possible implementation, when the driving mode is the pure electric priority mode, the energy-saving hybrid mode, the comfortable hybrid mode, the rain and snow mode or the sports mode, if the power supply state of the vehicle is turned off and then turned on again, the driving mode of the vehicle is set to the pure electric priority mode by default. When the driving mode is the pure electric priority mode, if the power supply state of the vehicle is turned off and then turned on again, the driving mode of the vehicle is set to the pure electric priority mode by default.

[0052] Optionally, the target battery capacity of the power battery can also be set through the mobile phone APP. For example, setting the target battery capacity of the power battery includes: in response to receiving the second information, the ICC sends the second information to the FLZCU, the second information being the setting information of the target battery capacity; in response to receiving the second information, the FLZCU forwards the second information to the HCU; and in response to receiving the second information, the HCU controls the capacity of the power battery of the vehicle to be maintained within the range of the target battery capacity.

[0053] In a possible implementation, after the passenger sets the target capacity of the battery through the mobile phone APP, the mobile phone APP sends the second information to the ICC through Bluetooth or a wireless network. After receiving the second information, the ICC sends the second information to the FLZCU through the CAN bus. After receiving the second information, the FLZCU forwards the second information to the HCU through the CAN bus. After receiving the second information, the HCU controls the capacity of the power battery of the vehicle to be maintained within the range of the target battery capacity through the BMS. Optionally, the range of the target battery capacity can be set according to experience.

[0054] Optionally, after the HCU controls the power battery of the vehicle to maintain the power of the power battery within the range of the target battery power, in response to the power of the power battery exceeding the range of the target battery power, the HCU transmits third information to the FLZCU, the third information being information that the power of the power battery exceeds the range of the target battery power; in response to receiving the third information, the FLZCU forwards the third information to the ICC; and the ICC displays the third information.

[0055] Exemplarily, after the setting of the target battery power is completed, the HCU continues to monitor the power of the power battery through the BMS, and if the power of the power battery exceeds the range of the target battery power, the HCU transmits third information to the FLZCU through the CAN bus. After receiving the third information, the FLZCU forwards the third information to the ICC through the CAN bus. After receiving the third information, the ICC displays the third information in a manner including but not limited to displaying that the power of the power battery exceeds the range of the target battery power on a screen of a center console of the vehicle.

[0056] In a possible implementation, the passenger can also set a personalized driving mode through a mobile phone APP, for example, the passenger can autonomously set the power mode to the hybrid mode and the power preservation mode to the forced power preservation mode through the mobile phone. In response to receiving the fourth information, the ICC sends the fourth information to the FLZCU, the fourth information being personalized driving mode setting information; in response to receiving the fourth information, the FLZCU determines fourth power mode information and fourth power preservation mode information corresponding to the fourth information; the FLZCU transmits the fourth power mode information and the fourth power preservation mode information to the HCU; in response to receiving the fourth power mode information and the fourth power preservation mode information, the HCU controls the operation of the vehicle based on a fourth power mode corresponding to the fourth power mode information and a fourth power preservation mode corresponding to the fourth power preservation mode information, so that the vehicle is in the personalized driving mode. The minimum power threshold of the power battery in the forced power preservation mode is less than the minimum power threshold of the power battery in the second power preservation mode.

[0057] In the embodiments of the present application, after receiving the driving mode setting information, the ICC sends the driving mode setting information to the FLZCU, so as to facilitate the FLZCU to switch the driving mode; when receiving the driving mode setting information, the FLZCU determines the first power mode information and the first power saving mode information corresponding to the driving mode setting information, and determines the power mode and the power saving mode corresponding to the set driving mode, so as to facilitate the control of the power mode and the power saving mode of the vehicle according to the set driving mode; the FLZCU further 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, so as to control the vehicle to be in the set driving mode, and realize the control of the power mode and the power saving mode of the vehicle according to the set driving mode, so that the power mode and the power saving mode of the vehicle meet the required state in the set driving mode, and the energy efficiency of the vehicle is improved, the performance of the vehicle is optimized, and the safety of driving is improved.

[0058] In the example embodiments, a vehicle driving mode control system is also provided, which includes an ICC, a FLZCU and an HCU, and is configured to perform any of the above vehicle driving mode control methods.
