[0032] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] As mentioned above, how to intelligently plan and control vehicle power and fuel levels during travel has become an important research issue.

[0035] Based on the above description, if Figure 1 As shown, the vehicle control method proposed in this embodiment is applied to the vehicle side and is suitable for hybrid vehicles. The method includes:

[0036] Step 101: Obtain the remaining battery power and / or the remaining fuel level in the fuel tank.

[0037] In specific implementations, the remaining battery charge is the current remaining charge of the vehicle's battery pack, and the remaining fuel level is the current remaining fuel level in the vehicle's fuel tank. The remaining battery charge and / or remaining fuel level in the fuel tank are obtained in real time.

[0038] For example, the current power status and / or fuel status are acquired in real time through sensors to obtain the remaining battery power and / or the remaining fuel tank capacity.

[0039] The process of obtaining the remaining battery power can also be as follows: the vehicle hybrid system controller (Vehicle Control Unit, VCU) calculates the remaining battery power of the power battery pack (Battery Management System, BMS) in real time to obtain the remaining battery power.

[0040] Step 102 : Calculate the electric driving range of the vehicle in pure electric mode based on the remaining battery power.

[0041] In pure electric mode, the engine is not running, and the power battery is fed into the P2 motor, which then drives the wheels via the transmission, final drive, and differential. This is primarily suitable for vehicle start-up and low- to medium-speed urban driving conditions.

[0042] Pure electric mode relies solely on the power battery to propel the vehicle. The vehicle's electric range in pure electric mode is calculated based on the remaining battery charge, the power consumption per 100 kilometers, and a preset reserve charge. The electric range is the vehicle's range in pure electric mode, determined based on the remaining battery charge.

[0043] Step 103 , calculating the extended range of the vehicle in the direct drive mode of the engine according to the remaining fuel amount in the fuel tank.

[0044] In specific implementation, engine direct drive mode means the engine is running, the clutch is engaged, and the engine power drives the wheels through the transmission, final drive, and differential, with the engine operating at high efficiency. This is mainly suitable for high-speed driving.

[0045] Direct engine drive mode relies solely on the engine to propel the vehicle. The extended range in direct engine drive mode is calculated based on the remaining fuel in the tank and fuel consumption per 100 kilometers. The extended range is the vehicle's range in direct engine drive mode, determined based on the remaining fuel in the tank.

[0046] Step 104 : determining a vehicle cruising state based on the electric cruising range and the extended-range cruising range, and controlling the vehicle using a corresponding strategy based on the vehicle cruising state during the vehicle's travel.

[0047] In specific implementations, the vehicle's cruising state is determined based on the electric cruising range and the extended range. The vehicle's cruising state is the total cruising range, which is the sum of the electric cruising range in pure electric mode and the extended range in engine direct drive mode.

[0048] While the vehicle is in motion, the total mileage of the vehicle's journey is obtained. For example, during a camping trip, the total mileage of the camping trip is obtained. Based on the vehicle's endurance status and the total mileage of the camping trip, it is determined whether the vehicle can normally complete the round trip. Based on the different vehicle endurance statuses, corresponding vehicle control strategies are implemented, such as switching drive modes or reducing energy consumption through energy recovery, and reminding the user to charge or refuel the vehicle to avoid the vehicle being unable to complete the round trip due to low battery or fuel tank levels.

[0049] Step 105 , determining that the vehicle has arrived at the destination, starting the smart energy management mode, and calculating the safe power of the smart energy management mode.

[0050] During specific implementation, after the vehicle arrives at the destination, the vehicle starts the smart energy management mode and calculates the safe power of the smart energy management mode. For example, when the vehicle is camping, the smart energy management mode is the camping mode. When the vehicle arrives at the camping destination, the vehicle starts the camping mode and calculates the safe power of camping. The camping mode is a mode that the vehicle starts when the user is tired of camping at the destination and takes a rest in the car, allowing the user to take a rest for camping. After receiving the camping mode start instruction, the central electronic control module (CEM) on the vehicle side determines the parking status and determines whether the engine range extender is started. If it is determined that the engine range extender is not started, the vehicle hybrid system controller VCU calculates the camping safety power of the battery pack in real time, and the system starts the camping mode normally.

[0051] When camping mode is on, the vehicle system performs the following actions to enable the vehicle to operate at the lowest energy consumption. The actions performed by the vehicle system in camping mode are: (1) The front seat backrests fold backward and connect with the rear seat, while the seat cushions are raised to eliminate the step; the rear seat backrests fold backward to the maximum, connecting the front and rear seats to form a large bed mode for rest in the vehicle; (2) The windows are closed and the four doors are locked; (3) The headlights automatically turn off after a 30-second delay (adjustable); (4) The multimedia screen turns off and the music is turned off; (5) The air conditioner operates at the lowest energy consumption to ensure the indoor temperature is 26°C (adjustable between 24-28°C according to individual needs).

[0052] Step 106 : In response to determining that the safety power level is lower than a preset first power threshold, exit the smart energy management mode.

[0053] In specific implementation, when the safety power level is lower than the preset first power threshold, in order to ensure that there is sufficient power to return, the system prompts that the safety power level is insufficient and exits the smart energy management mode.

[0054] In the above embodiment, the electric cruising range of the vehicle in pure electric mode is calculated based on the remaining battery charge. The extended-range cruising range of the vehicle in engine direct drive mode is calculated based on the remaining fuel in the fuel tank. The vehicle's cruising range is determined based on the electric cruising range and the extended-range cruising range, and a corresponding strategy is adopted to control the vehicle according to the vehicle's cruising range during the vehicle's driving journey. Intelligent planning and control of the vehicle's battery and fuel levels can be achieved, allowing users to promptly understand the vehicle's remaining battery and fuel levels. In addition, the vehicle is controlled using a corresponding strategy based on the vehicle's cruising range to avoid excessive consumption of the vehicle's battery and fuel levels that affects the user's driving experience. When the vehicle arrives at its destination, the smart energy management mode is activated, and the safety power level of the smart energy management mode is calculated. In response to determining that the safety power level is lower than a preset first power threshold, the smart energy management mode is exited. When the safety power level is exhausted, the smart energy management mode is promptly exited to avoid the problem of insufficient power reserve for the return trip.

[0055] In some embodiments, step 102 includes:

[0056] Step 1021: Determine the route type.

[0057] In specific implementations, the vehicle's electric range in pure electric mode is calculated. Before calculating the electric range, the type of journey is determined. These journey types include normal and complex road sections. Different journey types have different power consumption per 100 kilometers. The journey can consist entirely of normal or complex road sections, or a mixture of normal and complex road sections. Different calculation methods are used for different journey types.

[0058] Step 1022, in response to determining that the route type is a normal road section, a first electric cruising range is obtained by calculating based on the remaining battery power, the preset reserved power and the power consumption per 100 kilometers.

[0059] In a specific implementation, when the route type is a normal road section, a first electric cruising range is obtained, wherein the first electric cruising range is the electric cruising range of the vehicle when traveling on a normal road section in pure electric mode.

[0060] The calculation process for the first electric cruising range is: First Electric Cruising Range = (Battery Remaining Charge - Preset Reserve Charge) ÷ Electricity Consumption per 100 km. The preset reserve charge is the amount of power reserved for user rest. For example, if the preset reserve charge is 50% of the total battery charge, then the First Electric Cruising Range = (Battery Remaining Charge - 50% × Total Battery Charge) ÷ Electricity Consumption per 100 km.

[0061] Step 1023 : In response to determining that the route type is a complex road section, a second electric cruising range is calculated based on the first electric cruising range and a preset power consumption coefficient.

[0062] In a specific implementation, when the route type is a complex road section, a second electric cruising range is obtained. The second electric cruising range is the electric cruising range of the vehicle traveling on the complex road section in pure electric mode. Complex roads include mountainous roads. Due to the complex outdoor rugged road conditions such as uphill and downhill sections, the power consumption per 100 kilometers on complex roads is higher than that per 100 kilometers on normal roads. The power consumption per 100 kilometers on complex roads is calculated as a preset multiple of the power consumption per 100 kilometers on normal roads, where the preset multiple is a preset power consumption coefficient.

[0063] The second electric cruising range is calculated as follows: Second electric cruising range = (remaining battery charge - preset reserve charge) ÷ (preset power consumption coefficient × power consumption per 100 kilometers) = First electric cruising range ÷ preset power consumption coefficient. For example, if the preset power consumption coefficient is 1.5, then the second electric cruising range = First electric cruising range ÷ 1.5.

[0064] In the above solution, the electric range in pure electric mode is calculated, allowing users to promptly understand the remaining battery charge and the electric range that can be traveled with the remaining battery charge. Because the power consumption per 100 kilometers on complex roads differs from that on normal roads, different methods are used to calculate the electric range based on the type of journey, ensuring that the calculated electric range is more accurate and in line with actual conditions.

[0065] In some embodiments, step 103 includes:

[0066] Step 1031: Determine the route type.

[0067] In specific implementations, the vehicle's extended range in direct engine drive mode is calculated. Before calculating the extended range, the type of journey is determined. These journey types include normal and complex road sections. Different journey types have different fuel consumption per 100 kilometers. The journey can be entirely normal, entirely complex, or partially normal and partially complex. Different calculation methods are used for different journey types.

[0068] Step 1032 : In response to determining that the route type is a normal road section, a first extended-range mileage is obtained by performing calculation based on the remaining fuel amount in the fuel tank and the fuel consumption per 100 kilometers.

[0069] In a specific implementation, when the route type is a normal road section, a first extended-range cruising range is obtained, wherein the first extended-range cruising range is the extended-range cruising range of the vehicle traveling on a normal road section in the engine direct drive mode.

[0070] The calculation process of the first extended-range cruising range is: first extended-range cruising range = remaining fuel in the tank ÷ fuel consumption per 100 kilometers.

[0071] Step 1033 : In response to determining that the route type is a complex road section, a second extended-range cruising range is calculated based on the first extended-range cruising range and a preset fuel consumption coefficient.

[0072] In a specific implementation, when the route type is a complex road section, a second extended-range cruising range is obtained. The second extended-range cruising range is the extended-range cruising range of the vehicle traveling on the complex road section in engine direct drive mode. Complex roads include mountainous sections. Due to the complex outdoor rugged conditions such as uphill and downhill sections, the fuel consumption per 100 kilometers on complex roads is higher than that on normal roads. The fuel consumption per 100 kilometers on complex roads is calculated as a preset multiple of the fuel consumption per 100 kilometers on normal roads, where the preset multiple is a preset fuel consumption coefficient.

[0073] The calculation process for the second extended-range range is: Second extended-range range = Remaining fuel in the tank / (Preset fuel consumption coefficient × Fuel consumption per 100 kilometers) = First extended-range range / Preset fuel consumption coefficient. For example, if the preset fuel consumption coefficient is 1.5, then the second extended-range range = First extended-range range / 1.5.

[0074] In the above solution, the extended-range range in direct-drive mode is calculated, allowing users to promptly understand the remaining fuel in the vehicle's tank and the extended-range range that can be traveled with that remaining fuel. Because fuel consumption per 100 kilometers on complex roads differs from that on normal roads, different extended-range range calculation methods are used based on the type of journey, ensuring more accurate and realistic calculations.

[0075] In some embodiments, step 104 includes:

[0076] Step 1041 , in response to determining that the electric cruising range is less than or equal to a preset electric cruising range threshold, exit the pure electric mode, start the engine direct drive mode, control the engine range extender to start and perform energy recovery.

[0077] In specific implementations, the total round-trip distance of the vehicle is obtained during driving. Based on the vehicle's cruising status and the total round-trip distance, it is determined whether the vehicle can complete the normal round-trip distance. Vehicle control strategies are then implemented based on the different cruising statuses.

[0078] When the electric range is less than or equal to the preset electric range threshold, the vehicle is determined to be unable to control driving in pure electric mode and is controlled to switch to engine direct drive mode. For example, when the electric range is less than or equal to 0 kilometers, the vehicle hybrid system controller (VCU) controls the engine range extender to start, activates engine direct drive mode, and exits pure electric mode. In addition, energy recovery is activated to charge the battery pack at maximum recovery efficiency.

[0079] Step 1042 , in response to determining that the electric cruising range is greater than a preset electric cruising range threshold, and the vehicle cruising state is greater than or equal to the total round-trip distance, controlling the vehicle according to the hybrid power strategy.

[0080] In specific implementations, when the electric range is greater than a preset electric range threshold and the vehicle's range status is greater than or equal to the total round-trip distance, the vehicle's remaining battery charge and fuel tank capacity are determined to be sufficient to complete the round-trip distance, and the vehicle is controlled according to the existing hybrid strategy. The vehicle's range status is the sum of the electric range and the extended-range range. For example, when the electric range is greater than 0 kilometers and the sum of the electric range and the extended-range range is greater than or equal to the total round-trip distance, the vehicle is controlled according to the existing hybrid strategy.

[0081] Step 1043, in response to determining that the electric cruising range is greater than a preset electric cruising range threshold and the vehicle cruising state is less than the total round-trip distance, a prompt is issued when the vehicle travels to a preset distance range from a gas station or a charging station.

[0082] In specific implementations, when the electric range exceeds a preset electric range threshold but the vehicle's range status is less than the total round-trip distance, the system determines that the vehicle can be controlled in pure electric mode, but the remaining battery charge and fuel tank level are insufficient to complete the round-trip distance. A notification is displayed when the vehicle is within a preset distance range from a gas station or charging station. The vehicle's range status is the sum of the electric range and the extended-range range. For example, if the electric range is greater than 0 kilometers but the sum of the electric range and the extended-range range is less than the total round-trip distance, the system calculates the distance between the vehicle and the gas station or charging station. When the vehicle is within the preset distance range from the gas station or charging station, a notification is displayed, reminding the user to refuel or charge.

[0083] In this solution, the vehicle's range, determined by the electric range and extended range, is controlled using corresponding strategies based on the vehicle's range. This allows for intelligent planning and control of the vehicle's battery and fuel levels, preventing the vehicle from completing a normal round trip due to low battery or fuel levels, and preventing excessive battery and fuel consumption that could impact the user's travel experience.

[0084] In some embodiments, further comprising:

[0085] Step 107 : Calculate the duration of the smart energy management mode based on the safe power level, and use the duration as the rest time.

[0086] In specific implementations, the duration of the Smart Energy Management mode is calculated based on the safety power level, and this duration is used as the rest time. The rest time calculation process is: Rest time = Safety power level / Smart Energy Management mode power consumption per minute. In addition, users can also set the rest time according to their needs.

[0087] Step 108 : Perform vehicle control in the smart energy management mode during the rest time.

[0088] In specific implementation, after the smart energy management mode is turned on, during rest time, the vehicle system performs the following actions to enable the vehicle to operate at the lowest energy consumption. The actions performed by the vehicle system in the smart energy management mode include: (1) the front seat backrests are folded back and connected to the rear seat, and the seat cushions are raised to eliminate the step; the rear seat backrests are folded back to the maximum, and the front and rear seats are connected to form a large bed mode, which is convenient for resting in the car; (2) the windows are closed and the four door locks are locked; (3) the headlights are automatically turned off after a delay of 30 seconds (which can be set); (4) the multimedia screen is turned off and the music is turned off; (5) the air conditioner operates at the lowest energy consumption to ensure the indoor temperature is 26℃ (which can be adjusted between 24-28℃ according to personal needs).

[0089] Step 109 : In response to determining that the rest time is over, exit the smart energy management mode.

[0090] In specific implementation, when the vehicle is in the smart energy management mode, it will exit the smart energy management mode when the safety power level is lower than the preset first power threshold, and will also exit the smart energy management mode at the end of the rest time.

[0091] When users are camping, the smart energy management mode is the camping mode, and the rest time is the camping time.

[0092] Exiting camping mode automatically occurs when the calculated or user-set camping time expires. To ensure a pleasant user experience when exiting camping mode, the multimedia interface includes beautiful music, allowing users to select a music playback mode: sequential, loop, or random. After playing a preset duration of beautiful music according to the user-set music playback mode, camping mode automatically exits. For example, after playing a one-minute random music playback, camping mode automatically exits.

[0093] The process for exiting camping mode when the camping safety battery level falls below the first battery threshold is as follows: When the camping safety battery level falls below the preset first battery threshold, to ensure sufficient battery for return flight, the system will issue a voice prompt notifying you of the low safety battery level and exit camping mode. For example, if the preset first battery threshold is 0, camping mode will be exited when the camping safety battery level falls below 0.

[0094] In the above solution, the smart energy management mode can be exited when the rest period ends or when the safety power level drops below the preset first power threshold. This allows users to set the smart energy management time according to their needs while ensuring sufficient power for return flight.

[0095] In some embodiments, step 105 includes:

[0096] Step 105A: Obtain a first distance between the vehicle and the charging station.

[0097] Step 105B: Calculate the safe power level based on the remaining battery power, the first distance, and the power consumption per 100 kilometers.

[0098] In practice, before calculating the safety charge, the extended range and return distance are first determined. If the extended range is greater than the return distance, the vehicle can complete the return trip in direct engine drive mode, and the safety charge calculation does not require the initial distance between the vehicle and the charging station.

[0099] To ensure the vehicle has enough remaining battery power to reach the nearest charging station on the return trip, calculate the vehicle's safety power. The safety power calculation process is: Safety power = remaining battery power - first distance × power consumption per 100 kilometers.

[0100] Step 105a: Obtain the total battery power.

[0101] Step 105b: Calculate the safe power according to the total power of the battery and a preset safety factor.

[0102] In specific implementation, when the vehicle can complete the return trip in direct engine drive mode, a safety capacity is calculated to ensure normal operation of the vehicle's battery pack. The safety capacity calculation process is: Safety capacity = total battery capacity × preset safety factor. For example, a preset safety factor of 10% ensures that the remaining battery capacity is at least 10% of the total battery capacity to ensure normal operation of the battery pack and avoid loss of battery life. In this case, the safety capacity = total battery capacity × 10%.

[0103] In the above solution, the safe power level is calculated based on the first distance between the vehicle and the charging station or a preset safety factor. This improves the user's experience of the smart energy management mode while ensuring that the user has sufficient power to charge at the charging station.

[0104] In some embodiments, after step 101, the method further includes:

[0105] Step 101A: In response to determining that the remaining battery power is less than or equal to a preset second power threshold, controlling the vehicle to enter a power saving mode.

[0106] In specific implementation, after the vehicle is powered on and driving, the vehicle hybrid system controller (VCU) calculates the remaining battery capacity of the power battery pack in real time. When the remaining battery capacity is less than or equal to a preset second capacity threshold, the vehicle is controlled to enter power saving mode. For example, the preset second capacity threshold is 50% of the total battery pack capacity. When the remaining battery capacity is less than or equal to 50% of the total battery pack capacity, the vehicle is controlled to enter power saving mode.

[0107] The actions performed by the vehicle system in power saving mode include: (1) the multimedia music and video functions in the vehicle cabin are turned off, and the vehicle screen is adjusted to power saving mode except for navigation needs; (2) the air conditioner is turned on or off according to the indoor temperature. When the indoor temperature is between 23℃ and 28℃, the air conditioner is kept running at the lowest energy consumption, and the air conditioner is switched to automatic mode (i.e., AUTO mode), and the air volume, temperature, and mode are all operated at the lowest energy consumption; when the indoor temperature is not between 23℃ and 28℃, the air conditioner is kept in the current on state; (3) the lights in the car (such as reading lights, wall lights, and ambient lights) are turned off; (4) the seat comfort functions of each seat in the cabin are turned off, such as seat heating, massage, and ventilation functions.

[0108] In the above solution, when the remaining battery charge calculated by the vehicle hybrid system controller (VCU) is less than or equal to a preset second charge threshold, the vehicle is controlled to enter power saving mode. This reduces power consumption and ensures that the vehicle has sufficient power to support the round trip and to enter smart energy management mode for rest after reaching the destination.

[0109] In the above embodiment, the electric cruising range of the vehicle in pure electric mode is calculated based on the remaining battery charge. The extended-range cruising range of the vehicle in engine direct drive mode is calculated based on the remaining fuel in the fuel tank. The vehicle's cruising range is determined based on the electric cruising range and the extended-range cruising range, and a corresponding strategy is adopted to control the vehicle according to the vehicle's cruising range during the vehicle's driving journey. Intelligent planning and control of the vehicle's battery and fuel levels can be achieved, allowing users to promptly understand the vehicle's remaining battery and fuel levels. In addition, the vehicle is controlled using a corresponding strategy based on the vehicle's cruising range to avoid excessive consumption of the vehicle's battery and fuel levels that affects the user's driving experience. When the vehicle arrives at its destination, the smart energy management mode is activated, and the safety power level of the smart energy management mode is calculated. In response to determining that the safety power level is lower than a preset first power threshold, the smart energy management mode is exited. When the safety power level is exhausted, the smart energy management mode is promptly exited to avoid the problem of insufficient power reserve for the return trip.

[0110] It should be noted that the embodiments of the present disclosure may be further described in the following manner:

[0111] The system obtains user camping requirements through navigation destination information. The multimedia system provides voice reminders to indicate whether camping mode is enabled. The driver can also proactively request to enable camping mode. After the driver confirms, the function is enabled. The following strategies are mainly implemented:

[0112] Scenario 1: After the vehicle is powered on and running, the vehicle hybrid system controller VCU starts to calculate the power of the power battery pack (BMS).

[0113] like Figure 2A As shown, Figure 2A This is a schematic diagram of the principle of the vehicle power saving mode according to an embodiment of the present disclosure.

[0114] ① When the battery pack power is ≤50%, the vehicle-related system performs the following actions:

[0115] The Head Unit (HUT) controls the in-car multimedia music and video functions, and adjusts the screen brightness to power-saving mode (except for navigation). The HVAC (Heating Ventilation and Air Conditioning) controller determines the air conditioning status (on or off) based on the current indoor temperature. When the indoor temperature is between 23°C and 28°C, the air conditioning is maintained at the lowest energy consumption and switches to automatic mode (i.e., AUTO mode), with air volume, temperature, and mode all operating at the lowest energy consumption. If the indoor temperature is not between 23°C and 28°C, the air conditioning remains on. The Central Electronic Control Module (CEM) turns off interior lights (such as reading lights, wall lights, and ambient lighting). The Seat Control Unit (SCU) turns off individual seat comfort features, such as seat heating, ventilation, and massage. The vehicle's hybrid system controller (VCU) monitors the remaining battery charge in the power battery pack (BMS) in real time and adjusts the hybrid mode. If the battery charge is less than 50%, the engine control unit (ECU) sends a signal to the engine control unit (ECU). The ECM turns on the engine, outputs to the Drive Motor Control Unit (DMCU), turns off the pure electric drive motor, and recovers energy in maximum recovery mode.

[0116] ② Based on the destination and route information in the navigation software, the system calculates the distance to the camping destination. Combined with the distance to the charging station along the way, the vehicle hybrid system controller (VCU) intelligently adjusts the power mode. The main strategies are as follows:

[0117] a. Figure 2B As shown, Figure 2B This is a schematic diagram of navigation path distances in an embodiment of the present disclosure. The system defines the distance to the camping destination as AE, identifies the distance to complex, uphill, and rough outdoor road conditions as CD, and the distance between the current location and the charging station and gas station as AB. Due to the complex outdoor conditions such as mountainous terrain, the fuel and electricity consumption on the CD section is calculated at 1.5 times the normal data.

[0118] b. For sections AC and DE:

[0119] (Battery remaining power - 0.5 × total battery power) ÷ Electricity consumption per 100 kilometers = First electric range Fuel tank remaining fuel ÷ Fuel consumption per 100 kilometers = First extended range

[0120] ① When the electric cruising range is less than 0 kilometers, the vehicle hybrid system controller will give priority to controlling the engine range extender to start, start the engine direct drive mode, exit the EV pure electric mode, and start energy recovery to charge the battery with maximum recovery efficiency. Figure 2C As shown, Figure 2C The schematic diagram of the principle of the hybrid system pure electric mode of the embodiment of the present disclosure is shown in FIG. When the battery pack power is less than 50%, the EV pure electric mode is turned off. Figure 2D As shown, Figure 2D The schematic diagram of the principle of the hybrid system engine direct drive mode of the embodiment of the present disclosure is shown in FIG. When the battery pack power is less than 50%, the engine direct drive mode is turned on. Figure 2E As shown, Figure 2E This is a schematic diagram of the principle of the hybrid system energy recovery mode of the embodiment of the present disclosure. When the battery pack power is less than 50%, energy recovery is enabled and recovered at maximum efficiency.

[0121] ② When the electric cruising range is greater than 0 kilometers and the electric cruising range + extended range is greater than 2*AE, it means that the vehicle has sufficient power and fuel to support the round trip and can be executed according to the original hybrid strategy.

[0122] ③ When the electric cruising range is greater than 0 km and the electric cruising range + extended range range is less than 2*AE, the system will start broadcasting refueling / charging reminders when (EV mode cruising range + EV mode cruising range) - AB ≤ 30 km.

[0123] c. For sections CD, fuel and electricity consumption are calculated at 1.5 times the normal figures, taking into account the special outdoor route. That is, the first electric range and the first extended-range range are both divided by 1.5. The remaining power mode adjustments and navigation reminder refueling and charging strategies are the same as for sections AC and DE.

[0124] d. The vehicle hybrid system controller (VCU) calculates the battery pack charge every 10 seconds, repeatedly determines the operating conditions of ①, ②, and ③, and performs intelligent control according to the above strategy.

[0125] Scenario 2: After arriving at the camping destination, you need to rest in the car due to the fatigue of camping. You can turn on the camping mode with one click to rest. The execution strategies of each system are as follows:

[0126] The central electronic control module (CEM) determines the vehicle is parked and the engine range extender is not activated. The vehicle hybrid system controller (VCU) calculates the battery pack's safe camping power. The system then enters camping rest mode, performing the following actions:

[0127] ① The multimedia controller HUT calculates the longest "camping mode" duration based on the current remaining pure electric power of the vehicle. You can freely choose the duration of the "camping mode" according to your needs.

[0128] The main calculation strategies are as follows:

[0129] a. Camping safety charge = remaining battery charge - initial distance between vehicle and charging station x power consumption per 100 kilometers (this may be disregarded if extended range mileage meets requirements);

[0130] b. Camping safety power = total battery power × 10%;

[0131] c. Camping safety power / air conditioner energy-saving mode power = maximum duration of camping mode (i.e. camping time).

[0132] ② After the camping rest mode is turned on, the vehicle system performs the following actions to enable the vehicle to operate with the lowest energy consumption.

[0133] a. The front seatbacks fold backward and connect to the rear seats, while the seat cushions lift up to eliminate the step. The rear seatbacks fold fully backward, connecting the front and rear seats to form a large bed for comfortable rest in the vehicle.

[0134] b. The windows are closed and all four doors are locked;

[0135] c. The lights will automatically turn off after 30 seconds (settable);

[0136] d. The multimedia screen goes off and the music is turned off;

[0137] e. The air conditioner operates at the lowest energy consumption to ensure an indoor temperature of 26°C (adjustable between 24-28°C according to individual needs);

[0138] Case 3: Exit camping mode.

[0139] After the rest time set in camping mode ends or the camping safety power is less than 0, the camping mode will be automatically exited.

[0140] ①After the set time is up, the camping mode will be automatically exited to ensure a comfortable exit. There are 10 soft music tracks set inside the multimedia. Users can choose single play, loop play, and random play mode. The system will automatically exit after one minute of play.

[0141] ② When the battery level for safe camping is less than 0, the voice system will prompt that the battery level is low to ensure sufficient power for return. To ensure the comfort and personal safety of the people in the car, the camping mode will be exited.

[0142] In the above embodiment, the intelligent power conservation camping mode can be conveniently turned on with one button, linked to the intelligent control of related systems, and the optimal power consumption strategy is calculated as a whole. The process calculation is accurate, eliminating the user's anxiety about power during the camping process, and avoiding the problem of being unable to return due to ignoring the power and fuel reservation for the return trip of camping for various reasons. It not only provides users with a convenient camping mode, but also achieves full energy saving, solving users' worries.
