[0060] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. 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, which 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 for a hybrid vehicle according to 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 a hybrid vehicle is powered on, it enters the Ready state, meaning it is about to start driving. At this point, the vehicle controller determines the ambient temperature using the vehicle's temperature sensor. In one possible implementation, the vehicle controller determines the ambient temperature of the hybrid vehicle's environment when the hybrid vehicle is powered on, thereby improving driving control efficiency. In another possible implementation, the vehicle controller determines the hybrid vehicle's lock time when the hybrid vehicle is powered on. If the hybrid vehicle's lock time is longer than a first preset time, it indicates that the hybrid vehicle has not been started for a long time, and the hybrid vehicle's battery temperature is likely low. In this case, the ambient temperature of the hybrid vehicle's environment is determined. If the hybrid vehicle's lock time is less than the first preset time, it indicates that the hybrid vehicle has just been started, and the battery temperature is often not very low. In this case, the ambient temperature of the hybrid vehicle's environment does not need to be determined, and the hybrid vehicle can be driven directly based on the hybrid vehicle's drive motor.
[0065] In another possible implementation, in cold areas (where the ambient temperature is lower than a third preset temperature), driving needs to be controlled according to the method provided in the embodiment of the present application; whereas in warm areas (where the ambient temperature is higher than the third preset temperature), the hybrid vehicle can be driven directly by 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 may be: when the hybrid vehicle is powered on, the vehicle controller determines the area type of the hybrid vehicle, and if the area type is a cold area, determines the ambient temperature of the environment in which the hybrid vehicle is located.
[0066] The vehicle controller determines the sum of the ambient temperatures and whether the ambient temperature is below a first preset temperature. If the ambient temperature is below the first preset temperature, step 202 is executed. If the ambient temperature is not below the first preset temperature, the hybrid vehicle is driven directly by the hybrid vehicle's drive motor. The first preset temperature can be set and modified as needed. In the present embodiment, the first preset temperature is not specifically limited. For example, the first preset temperature can be -15°C, -20°C, or -25°C.
[0067] Step 202: In the case that the ambient temperature is lower than the first preset temperature, the vehicle controller starts the engine of the hybrid vehicle, charges the battery of the hybrid vehicle through the engine, and starts the air conditioner of the hybrid vehicle to heat the battery and the cabin of the hybrid vehicle.
[0068] Because the discharge capacity of the battery is weak (the discharge power has a cliff drop) in a low-temperature environment, the battery not only needs to drive but also needs to heat the battery and the cabin. If the engine is not started to charge the battery, the driving power of the hybrid vehicle is weak and the hybrid vehicle is prone to power loss. Therefore, in the case that the ambient temperature is lower than the first preset temperature, the engine of the hybrid vehicle is immediately started to charge the battery of the hybrid vehicle through the engine; and the battery and the cabin are heated through the air conditioner to restore the discharge power of the battery as soon as possible.
[0069] Step 203: The vehicle controller determines the temperature of the battery cell; in the case that the temperature of the battery cell is lower than the second preset temperature, a target speed value matched with the temperature of the battery cell is determined based on the temperature of the battery cell; and the speed value of the engine is controlled to be the target speed value.
[0070] In a possible implementation, in the case that the temperature of the battery cell is lower than the second preset temperature, the vehicle controller controls the speed value of the engine to be the target speed value, that is, the speed of the engine does not change with the opening degree of the accelerator pedal, and only the torque of the engine changes with the acceleration demand; because the battery is heated, the temperature of the battery cell gradually increases, and the vehicle controller detects the temperature of the battery cell in real time; in the case that the temperature of the battery cell is higher than the second preset temperature, the vehicle controller releases the limitation of the speed value of the engine, and at this time, the engine and the torque both change with the acceleration demand, for example, please refer to Figure 3 , the temperature of the battery cell is -35℃, and in Figure 3 , the change curve of the opening degree of the accelerator pedal, the change curve of the speed of the engine, and the change curve of the vehicle speed during the driving process (specifically, the starting stage) of the hybrid vehicle are also shown.
[0071] In a possible implementation, the vehicle controller stores the corresponding relationship between the temperature of the battery cell and the speed value in advance, that is, one temperature of the battery cell corresponds to one speed value; correspondingly, the step of determining, by the vehicle controller, the target speed value matched with the temperature of the battery cell based on the temperature of the battery cell can be that the vehicle controller obtains the target speed value corresponding to the temperature of the battery cell from the corresponding relationship between the temperature of the battery cell and the speed value based on the temperature of the battery cell.
[0072] In another possible implementation, the vehicle controller implements the corresponding relationship between the storage cell temperature range and the speed value, that is, one cell temperature range corresponds to one speed value; accordingly, the step of the vehicle controller determining the target speed value that matches the cell temperature based on the cell temperature may be: the vehicle controller determines the cell temperature range to which the cell temperature belongs, and based on the cell temperature range, obtains the target speed value corresponding to the cell temperature range from the corresponding relationship between the cell temperature range and the speed value.
[0073] In this embodiment, to improve the hybrid vehicle's overall driving efficiency in ultra-low temperature environments, the vehicle controller maps different engine speeds based on different battery cell temperature ranges and maintains a fixed engine speed. This fixed engine speed is due to the hybrid vehicle's engine operating in range-extended mode (engine start mode) using speed control.
[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. Specifically, the greater the accelerator pedal opening, the greater the actual driving power of the drive motor, while the smaller the accelerator pedal opening, the smaller the actual driving power of the drive motor. In one possible implementation, the vehicle controller pre-stores a correspondence between accelerator pedal opening and driving power, where each accelerator pedal opening corresponds to a driving power. Accordingly, the step of determining the actual driving power of the hybrid vehicle's drive motor based on the accelerator pedal opening by the vehicle controller may include: the vehicle controller, based on the accelerator pedal opening, obtains the actual driving power of the drive motor from the correspondence between the accelerator pedal opening and driving power.
[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 hybrid vehicle's drive motor 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 drive motor. Accordingly, the step in which the vehicle controller determines the actual driving power of the drive motor of the hybrid vehicle based on the accelerator pedal opening may be: the vehicle controller reads the actual driving power of the drive motor at the accelerator pedal opening.
[0079] Step 205: The vehicle controller determines a 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 electricity generated by the generator in 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 achieved by the following steps (1) to (3), including:
[0081] (1) The vehicle controller determines the battery's peak charging power and battery continuous discharge power.
[0082] Battery Charging Power: Battery charging power is used to indicate the regenerative or motor charging capacity; therefore, the battery peak charging power is used to indicate the maximum regenerative or motor charging capacity. In one possible implementation, the battery peak charging power is fixed and stored in the vehicle controller. Accordingly, the vehicle controller may determine the battery peak charging power by: obtaining 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 the recent period; 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 can be: the vehicle controller obtains the battery peak charging power corresponding to the ambient temperature from the correspondence 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 can 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 generator's driving capability; therefore, the battery continuous discharge power is used to indicate the generator's continuous driving capability. In one possible implementation, the battery continuous discharge power is fixed and stored in the vehicle controller. Accordingly, the vehicle controller may determine the battery continuous discharge power by: obtaining the stored battery continuous discharge power.
[0087] In another possible implementation, the vehicle controller determines the battery's continuous discharge power based on the battery's charging power during a recent period. Accordingly, the vehicle controller may determine the battery's continuous discharge power by obtaining the battery's discharge power during a third preset time period before the current time, and determining the battery's continuous discharge power based on the battery's discharge power during the third preset time period. For example, if the third preset time period includes multiple sampling times, the vehicle controller may determine the battery's continuous discharge power based on the battery's discharge power during the third preset time period by determining the battery's continuous discharge power by averaging the battery's discharge power during the multiple sampling times to obtain the battery's 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 can be: the vehicle controller obtains the continuous discharge power of the battery corresponding to the ambient temperature from the correspondence 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 battery peak discharging power during the hybrid vehicle driving process (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 preset power can be set and changed as needed. In the embodiment of the present application, there is no specific limitation on the preset opening and preset power. For example, the preset opening is 10% and the preset power is 8800W. The available power of the air conditioner can be expressed as follows:
[0094] When the accelerator pedal opening is less than 10%, Min (battery peak discharge power, 8800W) = the available power of the air conditioner. When the accelerator pedal opening is greater than 10%, Min (battery continuous discharge power, 8800W) = the 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 air conditioner's available power, the battery's peak charging power, and the actual drive power of the drive motor to obtain the generator's first available power. In another possible implementation, the vehicle controller performs a weighted sum of the air conditioner's available power, the battery's peak charging power, and the actual drive power of the drive motor to obtain the generator's first available power.
[0098] The step of the vehicle controller controlling the generator to generate electricity based on the first available power may include: the vehicle controller determining an allowable power generation capacity of the engine based on the first available power; and controlling the generator to generate electricity based on the allowable power generation capacity of the engine, wherein the allowable power generation capacity is less than the first available power.
[0099] The vehicle controller monitors the engine water temperature in real time; when the engine water temperature is greater than a fourth preset temperature, the vehicle controller switches battery heating and passenger compartment heating to engine water heating, which not only improves driving comfort but also reduces the energy consumption of hybrid vehicles.
[0100] In one 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 requirement of 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 accelerator pedal opening range and the driving demand power, that is, one accelerator 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 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 driving demand power corresponding to the accelerator pedal opening range from the correspondence between the accelerator 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 stores 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 the vehicle controller determining the original generated power of the generator based on the driving demand power can 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 generated power, that is, one driving demand power range corresponds to one original generated power; accordingly, the step of the vehicle controller determining the original generated power of the generator based on the driving demand power 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 generated power corresponding to the driving demand power range from the correspondence between the driving demand power range and the original generated power.
[0107] (6) The vehicle controller determines the allowable power generation of the engine based on the original power generation power and the first available power.
[0108] When the original generated power is greater than the first available power, the vehicle controller determines the allowable generated power of the engine to be the first available power; when the original generated power is not greater than the first available power, the vehicle controller determines the allowable generated power of the engine to be the original generated power.
[0109] In an embodiment of the present application, the driving demand power is mapped to an original generated power; in an ultra-low temperature environment, the original generated power is constrained by the first available power, and the allowed generated 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 generated by the generator, determines the second available power of the drive motor based on the actual power generated by 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 drive motor and the power generation capacity of the generator can be improved; from the product dimension, the geographical range of hybrid vehicle use can be increased; for example, hybrid vehicles can be driven in ultra-low temperature geographical ranges; from the customer dimension, it is possible to get in the vehicle and drive away without having to wait for an empty vehicle, thereby improving vehicle user satisfaction.
[0113] In the embodiment of the present application, in an ultra-low temperature environment, by fixing the speed value of the engine, the actual driving power of the driving motor is increased with the increase of the accelerator pedal opening degree; the increase of the actual power of the driving motor leads to the increase of the first available power of the generator, the increase of the first available power of the generator leads to the increase of the actual power generation of the generator, and the increase of the actual power generation of the generator leads to the increase of the second available power of the driving motor, so that in an ultra-low temperature environment, the second available power of the driving motor and the first available power of the generator change steadily, and the stable second available power and first available power can make the hybrid vehicle maintain a certain vehicle speed to move steadily in an ultra-low temperature environment, thereby improving the geographical range of the hybrid vehicle from the product dimension; for example, the hybrid vehicle can travel in an ultra-low temperature geographical range; from the customer dimension, the vehicle can be driven as soon as it is boarded, without the need for empty vehicle waiting, thereby improving the vehicle satisfaction.
[0114] Please refer to Figure 4 which shows a flowchart of a driving control method of a hybrid vehicle according to an example embodiment of the present application. Please refer to Figure 4 The method comprises the following steps.
[0115] Step 401: When the hybrid vehicle is powered on, the vehicle controller determines the ambient temperature of the environment where the hybrid vehicle is located.
[0116] In some embodiments, this step is the same as step 201, which 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, charges 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.
[0118] In some embodiments, this step is the same as step 202, which will not be repeated here.
[0119] Step 403: The vehicle controller determines the battery cell temperature; when the cell temperature is lower than the second preset temperature, a target speed value matched with the cell temperature is determined based on the cell temperature; and the speed value of the engine is controlled at the target speed value.
[0120] In some embodiments, this step is the same as step 203, which will not be repeated here.
[0121] Step 404: The vehicle controller determines the accelerator pedal opening degree of the hybrid vehicle, and determines the actual driving power of the driving motor of the hybrid vehicle based on the accelerator pedal opening degree.
[0122] In some embodiments, this step is the same as step 204, which 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 in 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 of the engine's requested torque during the driving process of the hybrid vehicle (specifically, the starting phase).
[0127] The vehicle controller may determine the initial torque of the engine based on the allowed power generation and the target speed of the engine. The vehicle controller may determine 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 achieved 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 sum 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 a variation curve of the maximum allowable torque and a variation curve of the minimum allowable torque during the driving process of the hybrid vehicle (specifically, the starting phase).
[0136] Among them, the steps for the vehicle controller to determine the requested torque of the engine based on the original torque, the allowable maximum torque and the allowable minimum torque may be: when the original torque is greater than the allowable minimum torque and less than the allowable maximum torque, the vehicle controller determines that the requested torque of the engine is the original torque; when the original torque is greater than the allowable maximum torque, the vehicle controller determines that the requested torque of the engine is the allowable maximum torque; when the original torque is less than the allowable minimum torque, the vehicle controller determines that the requested torque of the engine is the allowable minimum torque.
[0137] Step 407: The vehicle controller determines the actual power generated by the generator, determines the second available power of the drive motor based on the actual power generated by 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 a user is driving a hybrid vehicle (especially in the initial stage of the hybrid vehicle), the accelerator pedal opening of the hybrid vehicle is 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 allowable power generation of the engine to gradually increase. The allowable power generation power increases while the engine speed value remains unchanged. Under the constraints of the allowable maximum torque and 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 through the above steps 403-407, the second available power of the drive motor and the first available power of the generator will 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 by 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, it can increase the geographical range of hybrid vehicle use; for example, hybrid vehicles can be driven in an ultra-low temperature geographical range; from a customer perspective, 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.
