For example, the ambient temperature, battery cell temperature and accelerator pedal opening involved in this application are all obtained with full authorization.

[0061] Please refer to Figure 1 , which shows a schematic diagram of the implementation environment of the driving control method of a hybrid vehicle shown in an exemplary embodiment of the present application. The implementation environment includes a hybrid vehicle 101, and the hybrid vehicle 101 is a hybrid electric vehicle (HEV) or a plug-in hybrid electric vehicle (PHEV). In addition, the hybrid vehicle 101 is equipped with a vehicle controller, an engine, a generator, a drive motor and a battery; the function of the vehicle controller is to control the generator, the generator and the drive motor. The function of the engine is to drive the engine to generate electricity; and the engine does not directly drive the wheels, but generates electricity by driving the generator. The function of the generator is to convert the mechanical energy generated by the engine into electrical energy, and provide the generated electrical energy to the drive motor or charge the battery. The drive motor is the power output device of the hybrid vehicle, and the function of the drive motor is to directly drive the wheels; and the drive motor can obtain electrical energy from the battery or obtain electrical energy through the generator to provide power.

[0062] Please refer to Figure 2, which shows a flow chart of a driving control method of a hybrid vehicle shown in an exemplary embodiment of the present application. Figure 2 , the method comprising:

[0063] Step 201: When the hybrid vehicle is powered on, the vehicle controller determines the ambient temperature of the environment in which the hybrid vehicle is located.

[0064] When the hybrid vehicle is powered on, the hybrid vehicle will enter the Ready state, that is, the hybrid vehicle is about to start and drive. At this time, the vehicle controller determines the ambient temperature through the temperature sensor of the hybrid vehicle. In one possible implementation, when the hybrid vehicle is powered on, the vehicle controller determines the ambient temperature of the environment in which the hybrid vehicle is located, thereby improving the driving control efficiency. In another possible implementation, when the hybrid vehicle is powered on, the vehicle controller determines the locking time of the hybrid vehicle; when the locking time of the hybrid vehicle is greater than the first preset time, it means that the hybrid vehicle has not been started for a long time, and the battery temperature of the hybrid vehicle will be low. At this time, the ambient temperature of the environment in which the hybrid vehicle is located is determined; when the locking time of the hybrid vehicle is not greater than the first preset time, it means that the hybrid vehicle has just been started, and the battery temperature of the hybrid vehicle is often not very low. At this time, it is not necessary to determine the ambient temperature of the environment in which the hybrid vehicle is located, and the hybrid vehicle can be driven directly based on the driving motor of the hybrid vehicle.

[0065] In another possible implementation, in cold areas (ambient temperature is lower than the third preset temperature), it is necessary to control driving according to the method provided in the embodiment of the present application; in warm areas (ambient temperature is higher than the third preset temperature), the hybrid vehicle can be driven directly based on the drive motor of the hybrid vehicle; and after the hybrid vehicle enters the cold area, the vehicle controller will store the area type; accordingly, step 201 can be: when the hybrid vehicle is powered on, the vehicle controller determines the type of area where the hybrid vehicle is located, and when the area type is a cold area, determines the ambient temperature of the environment where the hybrid vehicle is located.

[0066] The vehicle controller determines the sum of the ambient temperatures and determines whether the ambient temperature is lower than the first preset temperature; if the ambient temperature is lower than the first preset temperature, step 202 is executed; if the ambient temperature is not lower than the first preset temperature, the hybrid vehicle is driven directly based on the drive motor of the hybrid vehicle. The first preset temperature can be set and changed as needed. In the embodiment of the present application, the first preset temperature is not specifically limited; for example, the first preset temperature can be -15°C, -20°C or -25°C, etc.

[0067] Step 202: When the ambient temperature is lower than the first preset temperature, the vehicle controller starts the engine of the hybrid vehicle to charge the battery of the hybrid vehicle through the engine, and turns on the air conditioner of the hybrid vehicle to heat the battery and the cockpit of the hybrid vehicle through the air conditioner.

[0068] Because in low temperature environment, the battery's discharge capacity is weak (discharge power drops drastically), the battery is not only responsible for driving but also for heating the battery and the cockpit. If the engine is not started to replenish power, the hybrid car's driving power is weak and it is easy to run out of power. Therefore, when the ambient temperature is lower than the first preset temperature, the hybrid car's engine is started immediately to charge the hybrid car's battery through the engine; and the battery and the cockpit are heated by the air conditioner to restore the battery's discharge power as soon as possible.

[0069] Step 203: The vehicle controller determines the battery cell temperature of the battery; when the battery cell temperature is lower than the second preset temperature, determines a target speed value matching the battery cell temperature based on the battery cell temperature; and controls the engine speed value to be controlled at the target speed value.

[0070] In a possible implementation, when the battery cell temperature is lower than the second preset temperature, the vehicle controller will control the engine speed value to be controlled at the target speed value, that is, the engine speed does not change with the accelerator pedal opening, and only the engine torque changes with the acceleration demand; and because the battery is heated, the battery cell temperature will gradually increase, and the vehicle controller will detect the battery cell temperature in real time; when the battery cell temperature is higher than the second preset temperature, the vehicle controller will release the engine speed value limit, and at this time both the engine and the torque will change with the acceleration demand, for example, please refer to Figure 3 , the cell temperature is -35℃, Figure 3 Also shown is a curve showing a change in the accelerator pedal opening, a curve showing a change in the engine speed, and a curve showing a change in the vehicle speed during the driving process of the hybrid vehicle (specifically, the starting phase).

[0071] In one possible implementation, the vehicle controller stores the correspondence between the battery cell temperature and the speed value in advance, that is, one battery cell temperature corresponds to one speed value; accordingly, the step of the vehicle controller determining the target speed value matching the battery cell temperature based on the battery cell temperature may be: the vehicle controller obtains the target speed value corresponding to the battery cell temperature from the correspondence between the battery cell temperature and the speed value based on the battery cell temperature.

[0072] In another possible implementation, the vehicle controller implements and stores the correspondence between the battery cell temperature range and the speed value, that is, one battery cell temperature range corresponds to one speed value; accordingly, the step of the vehicle controller determining the target speed value matching the battery cell temperature based on the battery cell temperature may be: the vehicle controller determines the battery cell temperature range to which the battery cell temperature belongs, and based on the battery cell temperature range, obtains the target speed value corresponding to the battery cell temperature range from the correspondence between the battery cell temperature range and the speed value.

[0073] In the embodiment of the present application, in an ultra-low temperature environment, in order to improve the driving efficiency of the hybrid vehicle, the vehicle controller maps different engine speeds based on different battery cell temperature ranges and fixes the engine speed. The reason for fixing the engine speed is that the hybrid vehicle uses a speed control mode in the extended range working mode (the working mode of starting the engine).

[0074] The second preset temperature can be set and changed as needed. In the embodiment of the present application, the second preset temperature is not specifically limited; for example, the second preset temperature can be -25°C or -30°C, etc.

[0075] Step 204: The vehicle controller determines the accelerator pedal opening of the hybrid vehicle, and determines the actual driving power of the driving motor of the hybrid vehicle based on the accelerator pedal opening.

[0076] The actual driving power of the drive motor is positively correlated with the accelerator pedal opening, that is, the larger the accelerator pedal opening, the larger the actual driving power of the drive motor, and the smaller the accelerator pedal opening, the smaller the actual driving power of the drive motor. In a possible implementation, the vehicle controller stores the corresponding relationship between the accelerator pedal opening and the driving power in advance, that is, one accelerator pedal opening corresponds to one driving power; accordingly, the step of the vehicle controller determining the actual driving power of the drive motor of the hybrid vehicle based on the accelerator pedal opening can be: the vehicle controller obtains the actual driving power of the drive motor from the corresponding relationship between the accelerator pedal opening and the driving power based on the accelerator pedal opening.

[0077] In another possible implementation, the vehicle controller stores in advance the correspondence between the accelerator pedal opening range and the driving power, that is, one accelerator pedal opening range corresponds to one driving power; accordingly, the step for the vehicle controller to determine the actual driving power of the drive motor of the hybrid vehicle based on the accelerator pedal opening may be: the vehicle controller determines the accelerator pedal opening range to which the accelerator pedal opening belongs based on the accelerator pedal opening, and based on the accelerator pedal opening range, obtains the actual driving power of the drive motor from the correspondence between the accelerator pedal opening range and the driving power.

[0078] In another possible implementation, the vehicle controller directly reads the actual driving power of the driving motor. Accordingly, the step in which the vehicle controller determines the actual driving power of the driving motor of the hybrid vehicle based on the accelerator pedal opening may be: the vehicle controller reads the actual driving power of the driving motor when the accelerator pedal is opened.

[0079] Step 205: The vehicle controller determines the first available power of the generator of the hybrid vehicle based on the actual driving power of the driving motor, controls the generator to generate electricity based on the first available power, and stores the electric energy generated by the generator into the battery.

[0080] The step of determining the first available power of the generator of the hybrid vehicle based on the actual driving power of the driving motor by the vehicle controller can be implemented by the following steps (1) to (3), including:

[0081] (1) The vehicle controller determines the battery peak charging power and battery continuous discharge power.

[0082] Battery charging power: Battery charging power is used to indicate the recovery or motor charging capacity; therefore, the battery peak charging power is used to indicate the recovery or motor maximum charging capacity. In a possible implementation, the battery peak charging power is fixed and stored in the vehicle controller; accordingly, the step of the vehicle controller determining the battery peak charging power of the battery may be: the vehicle controller obtains the stored battery peak charging power.

[0083] In another possible implementation, the vehicle controller determines the battery peak charging power based on the battery charging power in a recent period of time; accordingly, the step for the vehicle controller to determine the battery peak charging power of the battery may be: the vehicle controller obtains the battery charging power of the battery within a second preset time period before the current time, and based on the battery charging power of the battery within the second preset time period, determines the maximum value of the battery charging power to obtain the battery peak charging power.

[0084] In another possible implementation, different ambient temperatures correspond to different battery peak charging powers, and the vehicle controller obtains the battery peak charging power under the current environment; accordingly, the step for the vehicle controller to determine the battery peak charging power of the battery may be: the vehicle controller obtains the battery peak charging power corresponding to the ambient temperature from the corresponding relationship between the ambient temperature and the peak charging power based on the ambient temperature.

[0085] In another possible implementation, different battery cell temperatures correspond to different battery peak charging powers, and the vehicle controller obtains the battery peak charging power corresponding to the current battery cell temperature; accordingly, the step for the vehicle controller to determine the battery peak charging power of the battery may be: the vehicle controller obtains the battery peak charging power corresponding to the battery cell temperature from the correspondence between the battery cell temperature and the peak charging power based on the battery cell temperature.

[0086] Battery discharge power: Battery discharge power is used to indicate the driving capability of the generator; therefore, the battery continuous discharge power is used to indicate the continuous driving capability of the generator. In a possible implementation, the battery continuous discharge power is fixed and stored in the vehicle controller; accordingly, the step of the vehicle controller determining the battery continuous discharge power of the battery may be: the vehicle controller obtains the stored battery continuous discharge power.

[0087] In another possible implementation, the vehicle controller determines the battery continuous discharge power based on the battery charging power in the recent period; accordingly, the step of the vehicle controller determining the battery continuous discharge power of the battery may be: the vehicle controller obtains the battery discharge power of the battery within the third preset time before the current time, and determines the battery continuous discharge power based on the battery discharge power of the battery within the third preset time. For example, the third preset time includes multiple sampling times, and the step of the vehicle controller determining the battery continuous discharge power based on the battery discharge power of the battery within the third preset time may be: the vehicle controller determines the average value of the battery discharge power of multiple sampling times to obtain the battery continuous discharge power.

[0088] In another possible implementation, different ambient temperatures correspond to different continuous discharge powers of the battery, and the vehicle controller obtains the continuous discharge power of the battery under the current environment; accordingly, the step for the vehicle controller to determine the continuous discharge power of the battery may be: the vehicle controller obtains the continuous discharge power of the battery corresponding to the ambient temperature from the corresponding relationship between the ambient temperature and the continuous discharge power based on the ambient temperature.

[0089] In another possible implementation, different battery cell temperatures correspond to different battery continuous discharge powers, and the vehicle controller obtains the battery continuous discharge power corresponding to the current battery cell temperature; accordingly, the step for the vehicle controller to determine the battery continuous discharge power of the battery may be: the vehicle controller obtains the battery continuous discharge power corresponding to the battery cell temperature from the correspondence between the battery cell temperature and the continuous discharge power based on the battery cell temperature.

[0090] It should be noted that the battery continuous discharge power can also be replaced by the battery peak discharge power, which is used to indicate the maximum driving capacity of the generator; for example, please continue to refer to Figure 3, the curves of the battery peak charging power and the battery peak discharging power during the driving process of a hybrid vehicle (specifically the starting stage).

[0091] (2) The vehicle controller determines the available power of the air conditioner based on the accelerator pedal opening, battery peak charging power, and battery continuous discharge power.

[0092] When the accelerator pedal opening is less than the preset opening, the vehicle controller determines the minimum power between the battery peak charging power and the preset power, and determines the minimum power as the available power of the air conditioner; when the accelerator pedal opening is not less than the preset opening, the vehicle controller determines the minimum power between the battery continuous discharge power and the preset power, and determines the minimum power as the available power of the air conditioner.

[0093] The preset opening and the preset power can be set and changed as needed. In the embodiment of the present application, the preset opening and the preset power are not specifically limited; for example, the preset opening is 10%, and the preset power is 8800W; then the available power of the air conditioner can be expressed by the following expression:

[0094] When the accelerator pedal opening is less than 10%, Min (battery peak discharge power, 8800W) = available power of the air conditioner; when the accelerator pedal opening is greater than 10%, Min (battery continuous discharge power, 8800W) = available power of the air conditioner.

[0095] In the embodiment of the present application, the vehicle controller utilizes the battery capacity to provide the air conditioner with the maximum possible available power, thereby improving the heating efficiency of the air conditioner and shortening the battery heating time in an ultra-low temperature environment.

[0096] (3) The vehicle controller determines the first available power of the generator based on the available power of the air conditioner, the peak charging power of the battery, and the actual driving power of the driving motor.

[0097] In one possible implementation, the vehicle controller determines the sum of the available power of the air conditioner, the peak charging power of the battery, and the actual driving power of the drive motor to obtain the first available power of the generator. In another possible implementation, the vehicle controller performs a weighted summation of the available power of the air conditioner, the peak charging power of the battery, and the actual driving power of the drive motor to obtain the first available power of the generator.

[0098] The step of the vehicle controller controlling the generator to generate electricity based on the first available power may be: the vehicle controller determines the allowable power generation of the engine based on the first available power; and controls the generator to generate electricity based on the allowable power generation of the engine, wherein the allowable power generation is less than the first available power.

[0099] The vehicle controller monitors the water temperature of the engine in real time; when the water temperature of the engine is greater than the fourth preset temperature, the vehicle controller switches the battery heating and the passenger compartment heating to the engine water heating, which can not only improve the driving comfort but also reduce the energy consumption of the hybrid vehicle.

[0100] In a possible implementation, the step of determining the allowable power generation power of the engine based on the first available power by the vehicle controller can be implemented by the following steps (4) to (6), including:

[0101] (4) The vehicle controller determines the driving power required for the hybrid vehicle based on the accelerator pedal opening.

[0102] In one possible implementation, the vehicle controller stores in advance the correspondence between the accelerator pedal opening and the driving demand power, that is, one accelerator pedal opening corresponds to one driving demand power; accordingly, the step for the vehicle controller to determine the driving demand power of the hybrid vehicle based on the accelerator pedal opening may be: the vehicle controller obtains the driving demand power corresponding to the accelerator pedal opening from the correspondence between the accelerator pedal opening and the driving demand power based on the accelerator pedal opening.

[0103] In another possible implementation, the vehicle controller stores in advance the correspondence between the throttle pedal opening range and the driving demand power, that is, one throttle pedal opening range corresponds to one driving demand power; accordingly, the step for the vehicle controller to determine the driving demand power of the hybrid vehicle based on the throttle pedal opening may be: the vehicle controller determines the throttle pedal opening range to which the throttle pedal opening belongs based on the throttle pedal opening, and based on the throttle pedal opening range, obtains the driving demand power corresponding to the throttle pedal opening range from the correspondence between the throttle pedal opening range and the driving demand power.

[0104] (5) The vehicle controller determines the original power generation of the generator based on the driving demand power.

[0105] In one possible implementation, the vehicle controller implements storage of the correspondence between the driving demand power and the original generated power, that is, one driving demand power corresponds to one original generated power; accordingly, the step of determining the original generated power of the generator based on the driving demand power by the vehicle controller may be: the vehicle controller obtains the original generated power corresponding to the driving demand power from the correspondence between the driving demand power and the original generated power based on the driving demand power.

[0106] In another possible implementation, the vehicle controller implements storage of the correspondence between the driving demand power range and the original power generation power, that is, one driving demand power range corresponds to one original power generation power; accordingly, the step of determining the original power generation power of the generator based on the driving demand power by the vehicle controller may be: the vehicle controller determines the driving demand power range to which the driving demand power belongs based on the driving demand power, and based on the driving demand power range, obtains the original power generation power corresponding to the driving demand power range from the correspondence between the driving demand power range and the original power generation power.

[0107] (6) The vehicle controller determines the allowable power generation of the engine based on the original power generation and the first available power.

[0108] When the original power generation is greater than the first available power, the vehicle controller determines the allowable power generation of the engine to be the first available power; when the original power generation is not greater than the first available power, the vehicle controller determines the allowable power generation of the engine to be the original power generation.

[0109] In an embodiment of the present application, the driving demand power is mapped to an original power generation power; in an ultra-low temperature environment, the original power generation power is constrained by the first available power, and the allowed power generation power is output, thereby avoiding the problem of battery overcharging in an ultra-low temperature environment, thereby extending the battery life.

[0110] Step 206: The vehicle controller determines the actual power generation of the generator, determines the second available power of the drive motor based on the actual power generation of the generator, and outputs the second available power to the drive motor, so that the drive motor drives the hybrid vehicle based on the second available power.

[0111] The steps for the vehicle controller to determine the second available power of the drive motor based on the actual power generation power of the generator may be: the vehicle controller determines the peak discharge power of the battery and the actual power of the air conditioner; determines the second available power of the drive motor based on the peak discharge power of the battery, the actual power of the air conditioner and the actual power generation power of the generator; for example, the vehicle controller determines the sum of the peak discharge power of the battery and the actual power generation power of the engine to obtain the first power, determines the difference between the first power and the actual power of the air conditioner to obtain the second available power.

[0112] It should be noted that steps 204-206 are a cyclic execution process, that is, by cyclically executing steps 204-206, the driving ability of the driving motor and the power generation ability of the generator can be improved; from the product dimension, the geographical range of hybrid vehicle use can be improved; for example, hybrid vehicles can be driven in ultra-low temperature geographical ranges; from the customer dimension, it can be achieved that the vehicle can be driven as soon as the vehicle is in the vehicle, without having to wait for an empty vehicle, thereby improving vehicle user satisfaction.

[0113] In an embodiment of the present application, in an ultra-low temperature environment, by fixing the engine speed value, the actual driving power of the drive motor increases with the increase of the accelerator pedal opening; and the increase in the actual power of the drive motor will cause the first available power of the generator to increase, and the increase in the first available power of the generator will cause the actual power generation power of the generator to increase, and the increase in the actual power generation power of the generator will cause the second available power of the drive motor to increase, so that in the ultra-low temperature environment, the second available power of the drive motor and the first available power of the generator change steadily, and the stable second available power and first available power can enable the hybrid vehicle to maintain a certain vehicle speed and move forward steadily in the ultra-low temperature environment, so that from the product dimension, the geographical range of hybrid vehicle use can be improved; for example, hybrid vehicles can travel in ultra-low temperature geographical ranges; from the customer dimension, it can be achieved that the vehicle can be driven as soon as it is in the vehicle, without waiting for an empty vehicle, thereby improving vehicle user satisfaction.

[0114] Please refer to Figure 4 , which shows a flow chart of a driving control method of a hybrid vehicle shown in an exemplary embodiment of the present application. Figure 4 , the method comprising:

[0115] Step 401: When the hybrid vehicle is powered on, the vehicle controller determines the ambient temperature of the environment in which the hybrid vehicle is located.

[0116] In some embodiments, this step is the same as step 201 and will not be repeated here.

[0117] Step 402: When the ambient temperature is lower than the first preset temperature, the vehicle controller starts the engine of the hybrid vehicle to charge the battery of the hybrid vehicle through the engine, and turns on the air conditioner of the hybrid vehicle to heat the battery and the cockpit of the hybrid vehicle through the air conditioner.

[0118] In some embodiments, this step is the same as step 202 and will not be repeated here.

[0119] Step 403: The vehicle controller determines the battery cell temperature of the battery; when the battery cell temperature is lower than the second preset temperature, determines a target speed value matching the battery cell temperature based on the battery cell temperature; and controls the engine speed value to be controlled at the target speed value.

[0120] In some embodiments, this step is the same as step 203 and will not be repeated here.

[0121] Step 404: The vehicle controller determines the accelerator pedal opening of the hybrid vehicle, and determines the actual driving power of the driving motor of the hybrid vehicle based on the accelerator pedal opening.

[0122] In some embodiments, this step is the same as step 204 and will not be repeated here.

[0123] Step 405: The vehicle controller determines the first available power of the generator of the hybrid vehicle based on the actual driving power of the driving motor, determines the allowable power generation power of the engine based on the first available power, controls the generator to generate electricity based on the allowable power generation power of the engine, and stores the electric energy generated by the generator into the battery.

[0124] In some embodiments, this step is the same as step 205 and will not be repeated here.

[0125] Step 406: The vehicle controller determines the original torque of the engine based on the allowed power generation and the target speed value of the engine; determines the allowable maximum torque of the drive motor and the allowable minimum torque of the generator; determines the requested torque of the engine based on the original torque, the allowable maximum torque and the allowable minimum torque; and controls the engine based on the requested torque of the engine.

[0126] For example, please refer to Figure 3 ,exist Figure 3 2 shows a curve of the change in the requested torque of the engine during the driving process of the hybrid vehicle (specifically, the starting phase).

[0127] The vehicle controller determines the initial torque of the engine based on the allowed power generation and the target speed value of the engine. The vehicle controller determines the initial torque of the engine based on the following formula 1:

[0128] Formula 1: Allowable power generation = 2π*torque*speed.

[0129] The step of determining the original torque of the engine based on the allowed power generation and the target speed value of the engine by the vehicle controller can be implemented by the following steps (1) to (3), including:

[0130] (1) The vehicle controller determines the motor efficiency table and motor speed of the generator.

[0131] The motor efficiency table is used to indicate the energy conversion efficiency of the motor; the motor speed is the current speed of the generator.

[0132] (2) The vehicle controller determines the allowable maximum torque of the drive motor based on the second available power, the motor efficiency table and the motor speed.

[0133] The maximum allowable torque of the drive motor is used to constrain the torque of the drive motor so that the torque of the drive motor cannot exceed the maximum allowable torque. In one possible implementation, the vehicle controller determines the sum of the second available power, the motor efficiency table, and the motor speed to obtain the maximum allowable torque of the drive motor. In another possible implementation, the vehicle controller performs a weighted summation of the second available power, the motor efficiency table, and the motor speed to obtain the maximum allowable torque of the drive motor.

[0134] (3) The vehicle controller determines the allowable minimum torque of the generator based on the first available power, the motor efficiency table and the motor speed.

[0135] The minimum allowable torque of the generator is used to constrain the torque of the generator so that the torque of the generator cannot be lower than the minimum allowable torque. In one possible implementation, the vehicle controller determines the sum of the first available power, the motor efficiency table, and the motor speed to obtain the minimum allowable torque of the generator. In another possible implementation, the vehicle controller performs a weighted summation of the first available power, the motor efficiency table, and the motor speed to obtain the minimum allowable torque of the generator. For example, please continue to refer to Figure 3 ,exist Figure 3 2 shows the variation curve of the maximum allowable torque and the variation curve of the minimum allowable torque during the driving process of the hybrid vehicle (specifically, the starting phase).

[0136] Among them, the vehicle controller determines the requested torque of the engine based on the original torque, the allowable maximum torque and the allowable minimum torque in the steps as follows: when the original torque is greater than the allowable minimum torque and less than the allowable maximum torque, the vehicle controller determines the requested torque of the engine to be the original torque; when the original torque is greater than the allowable maximum torque, the vehicle controller determines the requested torque of the engine to be the allowable maximum torque; when the original torque is less than the allowable minimum torque, the vehicle controller determines the requested torque of the engine to be the allowable minimum torque.

[0137] Step 407: The vehicle controller determines the actual power generation of the generator, determines the second available power of the drive motor based on the actual power generation of the generator, and outputs the second available power to the drive motor, so that the drive motor drives the hybrid vehicle based on the second available power.

[0138] In some embodiments, this step is the same as step 206 and will not be repeated here.

[0139] One point that needs to be explained is that, when the user is driving a hybrid vehicle (especially in the initial stage of the hybrid vehicle), the accelerator pedal opening of the hybrid vehicle is a process of gradually increasing. At this time, the actual driving power of the drive motor will also gradually increase. The increase in the actual driving power of the drive motor will cause the first available power of the engine to gradually increase. The increase in the first available power will cause the allowable minimum torque and the allowable power generation of the engine to gradually increase. The allowable power generation increases while the engine speed remains unchanged. Under the constraints of the allowable maximum torque and the allowable minimum torque of the engine, the requested torque of the engine will also increase. The increase in the actual torque of the engine will cause the second available power of the drive motor to increase. Based on the above discussion, it can be seen that the above steps 403-407 will cause the second available power of the drive motor and the first available power of the generator to change steadily. The stable second available power and first available power can enable the hybrid vehicle to maintain a certain vehicle speed and move forward steadily in an ultra-low temperature environment.

[0140] The power distribution method in an ultra-low temperature environment provided in the embodiment of the present application utilizes spiral control to enhance both the driving capability of the drive motor and the power generation capability of the generator; from a product perspective, the geographical range of hybrid vehicle use can be increased; for example, hybrid vehicles can be driven in an ultra-low temperature geographical range; from a customer perspective, customers can get on the vehicle and drive without having to wait for an empty vehicle, thereby improving vehicle user satisfaction.
