[0049] To make the objectives, technical solutions, and advantages of the present disclosure more clearly understood, the following further describes the present disclosure in detail with reference to specific embodiments and the accompanying drawings.

[0050] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second", and similar terms used in the embodiments of the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different components. The terms "including" or "comprising" and the like mean that the elements or items appearing before this term cover the elements or items listed after this term and their equivalents, without excluding other elements or items. The terms "connected" or "coupled" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0051] Based on the description of the background art, for a pure electric vehicle, when in the launch mode, the vehicle outputs the maximum torque / power at the start to achieve the maximum acceleration and move forward, giving users an ultimate driving experience and driving pleasure. However, in the long run, for high-performance users, if the launch mode is frequently used for starting, the long-term and multiple outputs of the maximum torque will inevitably shorten the service life of the battery and even affect the vehicle's cruising range; for the electric drive system, the instantaneous peak torque will increase the pressure on the drive shaft and the reducer. After exceeding a certain limit number of times, or even in severe cases, it is easy to cause the drive shaft to break or the differential to be damaged.

[0052] When the vehicle is in a launch start, a large amount of energy needs to be released in a very short time, resulting in a sharp rise in the battery temperature. Therefore, frequent large-current discharges accelerate battery aging, thereby reducing the total number of battery cycles. For the electric drive system, the frequent output of the maximum torque and power causes the temperature of the motor winding to rise and overheat. When the maximum torque is output in a short time, the peak torque is transmitted to the wheels through the drive shaft. Limited by the mechanical stress of the drive shaft, frequent large-torque impacts will cause microscopic cracks to appear inside the material of the drive shaft under high-intensity loads. In the case of gradual accumulation, it will cause the risk of fatigue failure, excessive bending, or even fracture of the drive shaft. During the launch start process, the differential not only needs to transmit the powerful driving torque from the motor but also coordinate the different rotational speed requirements of the left and right wheels. Being under the peak torque for a long time is prone to structural damage, such as cracking of the housing.

[0053] As described above, how to avoid affecting the power system due to the long-term and frequent use of the launch start function has become an important research issue.

[0054] Based on the above description, as Figure 1 shown, for the vehicle control method proposed in this embodiment, the method includes:

[0055] Step 101, after the launch start function is activated, obtain the number of launch starts, and compare the number of launch starts with a preset number threshold.

[0056] Specifically, the number of launch starts is the number of times the vehicle controls the launch start according to the maximum power parameter within the time range from the factory to the current moment.

[0057] When the vehicle meets the starting conditions and receives the maximum power parameter, the launch start function is activated. To avoid affecting the power system due to long-term frequent control of the vehicle's launch start according to the maximum power parameter, by determining whether the number of launch starts reaches the preset number threshold, it is possible to accurately determine whether the vehicle's launch start function has reached the frequent use times, and thus accurately determine whether controlling the vehicle's launch start according to the maximum power parameter will affect the vehicle's power system.

[0058] For example, the preset number threshold is 500 times. After the launch start function is activated, obtain the number of launch starts and determine whether the number of launch starts reaches 500 times. When the number of launch starts is less than 500 times, it means that controlling the vehicle's launch start according to the maximum power parameter will not affect the vehicle's power system. When the number of launch starts is greater than or equal to 500 times, it means that controlling the vehicle's launch start according to the maximum power parameter will affect the vehicle's power system.

[0059] Step 102, in response to determining that the number of launch starts is less than the preset number threshold, control the vehicle's launch start according to the first power parameter.

[0060] Specifically, the number threshold is the critical number of launch starts that is preset to have an impact on the vehicle's power system. The first power parameter is the maximum power parameter that the motor can output. Among them, the first power parameter can be the maximum power or the maximum torque that the motor can output.

[0061] When the number of launch starts is less than the preset number threshold, it means that controlling the vehicle's launch start according to the maximum power parameter will not affect the vehicle's power system. In this scenario, to ensure the user's driving requirement for controlling the vehicle's launch start, control the vehicle's launch start according to the first power parameter (i.e., the maximum power parameter).

[0062] For example, the first power parameter (maximum power) is 200 kW, the preset number threshold is 500 times. When the number of catapult starts is 350 times, the vehicle catapult start is controlled according to the first power parameter of 200 kW. Another example, the first power parameter (maximum torque) is 340 N·m, the preset number threshold is 500 times. When the number of catapult starts is 350 times, the vehicle catapult start is controlled according to the first power parameter of 340 N·m.

[0063] Step 103, in response to determining that the number of catapult starts is greater than or equal to the preset number threshold, control the vehicle to start according to the second power parameter; wherein, both the first power parameter and the second power parameter are parameters for controlling the motor drive, and the second power parameter is less than the first power parameter.

[0064] In specific implementation, the second power parameter is less than the first power parameter. In order to control the vehicle to start according to the second power parameter without affecting the vehicle's power system and at the same time maximizing the user's driving demand for controlling the vehicle to start with greater power, the difference between the second power parameter and the first power parameter is a preset value.

[0065] For example, the first power parameter (maximum power) is 200 kW, the preset value is 10 kW, then the second power parameter is 190 kW. Another example, the first power parameter (maximum torque) is 340 N·m, the preset value is 10 N·m, then the second power parameter is 330 N·m.

[0066] When the number of catapult starts is greater than or equal to the preset number threshold, it means that controlling the vehicle catapult start according to the maximum power parameter will affect the vehicle's power system. In this scenario, in order not to affect the vehicle's power system and at the same time maximizing the user's driving demand for controlling the vehicle to start with greater power, the vehicle start is controlled according to the second power parameter which is less than the maximum power parameter.

[0067] For example, the second power parameter (second power) is 190 kW, the preset number threshold is 500 times. When the number of catapult starts is 500 times, the vehicle start is controlled according to the second power parameter of 190 kW. Another example, the second power parameter (second torque) is 330 N·m, the preset number threshold is 500 times. When the number of catapult starts is 500 times, the vehicle start is controlled according to the second power parameter of 330 N·m.

[0068] Through the above embodiments, after the launch start function is activated, the number of launch starts is obtained, and the number of launch starts is compared with a preset number threshold. When the number of launch starts is less than the preset number threshold, the vehicle launch start is controlled according to the first power parameter, and the motor drive is controlled according to the first power parameter, which can ensure the normal use of the launch start function by the user. When the number of launch starts is greater than or equal to the preset number threshold, the vehicle start is controlled according to the second power parameter; wherein, both the first power parameter and the second power parameter are parameters for controlling the motor drive, and the second power parameter is less than the first power parameter. In this way, when the number of launch starts reaches the preset number threshold, the motor drive is controlled according to the second power parameter that is less than the first power parameter, which can control the vehicle to start with a greater driving force, and at the same time can avoid the situation of overheating of the power system caused by long-term frequent use of the first power parameter to control the motor drive, realizing the protection of the power system.

[0069] In some embodiments, step 102 includes:

[0070] Step 1021, in response to determining that the number of launch starts is less than the preset number threshold, obtain the first motor characteristic curve.

[0071] Step 1022, determine the first power parameter corresponding to the current motor speed according to the first motor characteristic curve, and control the vehicle launch start according to the first power parameter.

[0072] Specifically, the first motor characteristic curve is a relationship curve between the motor speed and the power parameter in the launch start mode. Among them, the first motor characteristic curve can be a relationship curve between the motor speed and the power in the launch start mode, or a relationship curve between the motor speed and the torque in the launch start mode.

[0073] For example, when the first motor characteristic curve is a relationship curve between the motor speed and the power in the launch start mode, when the number of launch starts is less than the preset number threshold, obtain the first motor characteristic curve, determine the first power (maximum power) corresponding to the current motor speed according to the first motor characteristic curve, and control the vehicle launch start according to the first power.

[0074] Another example is that when the first motor characteristic curve is a relationship curve between the motor speed and the torque in the launch start mode, when the number of launch starts is less than the preset number threshold, obtain the first motor characteristic curve, determine the first torque (maximum torque) corresponding to the current motor speed according to the first motor characteristic curve, and control the vehicle launch start according to the first torque.

[0075] Through the above solution, the first motor characteristic curve is the relationship curve between the motor speed and the power parameter in the catapult start mode. In this way, when the number of catapult starts is less than the preset number threshold, the first power parameter (maximum power parameter) can be accurately obtained according to the first motor characteristic curve, so that the vehicle catapult start can be controlled according to the first power parameter, thus meeting the driving needs of users to control the vehicle catapult start.

[0076] In some embodiments, step 1022 includes:

[0077] Step 1022A, determining a first motor speed threshold based on the first motor characteristic curve, and comparing the current motor speed with the first motor speed threshold.

[0078] Step 1022B, in response to determining that the current motor speed is less than or equal to the first motor speed threshold, taking a first preset torque as the first power parameter.

[0079] Step 1022C, in response to determining that the current motor speed is greater than the first motor speed threshold, taking the first torque value corresponding to the current motor speed in the first motor characteristic curve as the first power parameter.

[0080] Step 1022D, controlling the motor based on the first power parameter to control the vehicle catapult start.

[0081] Specifically, Figure 2 is a schematic diagram of the motor characteristic curve of the embodiment of the present disclosure. As Figure 2 shown, Figure 2 the curve 1 in

[0082] is the first motor characteristic curve, where the abscissa is the motor speed and the ordinate is the power parameter (torque). Figure 2 In the curve 1 of

[0083] With the above solution, when the current motor speed is less than or equal to the first motor speed threshold, the first preset torque is used as the first power parameter; when the current motor speed is greater than the first motor speed threshold, the first torque value corresponding to the current motor speed in the first motor characteristic curve is used as the first power parameter. In this way, when the number of catapult starts is less than the preset number threshold, the first power parameter can be accurately obtained according to the first motor characteristic curve, and the motor is controlled based on the first power parameter, so as to realize the catapult start of the vehicle.

[0084] In some embodiments, step 103 includes:

[0085] Step 1031, in response to determining that the number of catapult starts is greater than or equal to the preset number threshold, obtain the second motor characteristic curve.

[0086] Step 1032, determine the second power parameter corresponding to the current motor speed according to the second motor characteristic curve, and control the vehicle to start according to the second power parameter.

[0087] Specifically, the second motor characteristic curve is the relationship curve between the motor speed and the power parameter in the large-power start mode. Among them, the second motor characteristic curve can be the relationship curve between the motor speed and the power in the large-power start mode, or the relationship curve between the motor speed and the torque in the large-power start mode.

[0088] For example, when the second motor characteristic curve is the relationship curve between the motor speed and the power in the large-power start mode, when the number of catapult starts is greater than or equal to the preset number threshold, obtain the second motor characteristic curve, determine the second power (less than the first power) corresponding to the current motor speed according to the second motor characteristic curve, and control the vehicle to start with a large power according to the second power.

[0089] Another example is that when the second motor characteristic curve is the relationship curve between the motor speed and the torque in the large-power start mode, when the number of catapult starts is greater than or equal to the preset number threshold, obtain the second motor characteristic curve, determine the second torque (less than the first torque) corresponding to the current motor speed according to the second motor characteristic curve, and control the vehicle to start with a large power according to the second torque.

[0090] With the above solution, the second motor characteristic curve is the relationship curve between the motor speed and the power parameter in the large-power start mode. In this way, when the number of catapult starts is greater than or equal to the preset number threshold, the second power parameter (less than the first power parameter) can be accurately obtained according to the second motor characteristic curve, so that the vehicle can be controlled to start with a large power according to the second power parameter, which can not only not affect the vehicle's power system, but also maximally meet the user's driving demand for controlling the vehicle to start with a large power.

[0091] In some embodiments, step 1032 includes:

[0092] Step 1032A, determining a second motor speed threshold based on the second motor characteristic curve and comparing the current motor speed with the second motor speed threshold.

[0093] Step 1032B, in response to determining that the current motor speed is less than or equal to the second motor speed threshold, taking a second preset torque as the second power parameter.

[0094] Step 1032C, in response to determining that the current motor speed is greater than the second motor speed threshold, taking the second torque value corresponding to the current motor speed in the second motor characteristic curve as the second power parameter.

[0095] Step 1032D, controlling the motor based on the second power parameter to control the vehicle to start.

[0096] Specifically, when implemented, Figure 2 is a schematic diagram of the motor characteristic curve of an embodiment of the present disclosure. As Figure 2 shown, Figure 2 Curve 2 in is the second motor characteristic curve, where the abscissa is the motor speed and the ordinate is the power parameter (torque).

[0097] In Figure 2 Curve 2 of, the second motor speed threshold is the motor speed N2. When the current motor speed is less than or equal to the motor speed N2, the second preset torque Tmax2 is taken as the second power parameter (second torque). When the current motor speed is greater than the motor speed N2, the second torque value corresponding to the current motor speed on curve 2 is taken as the second power parameter (second torque). The second power parameter (second torque) is output to the motor, and the motor is controlled based on the second power parameter (second torque) to achieve the start of the vehicle.

[0098] In addition, it can be seen from Figure 2 that when the current motor speeds are the same, the first power parameter corresponding to the first motor characteristic curve is less than the second power parameter corresponding to the second motor characteristic curve. In this way, when the number of catapult starts is less than the preset number threshold, the first power parameter (maximum power parameter) can be determined according to the first motor characteristic curve, and the vehicle can be controlled to perform a catapult start according to the first power parameter, meeting the driving needs of the user to control the vehicle to perform a catapult start; when the number of catapult starts is greater than or equal to the preset number threshold, the second power parameter (less than the first power parameter) can be determined according to the second motor characteristic curve, and the vehicle can be controlled to start according to the second power parameter, while not affecting the vehicle power system, maximizing the driving needs of the user to control the vehicle to start with a relatively large power.

[0099] With the above solution, when the current motor speed is less than or equal to the second motor speed threshold, the second preset torque is used as the second power parameter; when the current motor speed is greater than the second motor speed threshold, the second torque value corresponding to the current motor speed in the second motor characteristic curve is used as the second power parameter. In this way, when the number of catapult starts is greater than or equal to the preset number threshold, the second power parameter can be accurately obtained according to the second motor characteristic curve, and the motor is controlled based on the second power parameter, so as to realize the vehicle starting with greater power.

[0100] In some embodiments, after step 102, it further includes:

[0101] Step 102A, record this catapult start.

[0102] Step 102B, perform superposition processing on the number of catapult starts and this catapult start to obtain the superimposed number of catapult starts, and store the superimposed number of catapult starts.

[0103] Specifically, in order to accurately judge whether the vehicle has been frequently using the catapult start function for a long time, record and store the number of times of controlling the vehicle's catapult start from the vehicle's factory to the current moment, so as to judge whether the vehicle has been frequently using the catapult start function according to the number of catapult starts.

[0104] After controlling the vehicle's catapult start according to the first power parameter, record this catapult start. Perform superposition processing on the number of catapult starts and this catapult start to obtain the superimposed number of catapult starts, and store the superimposed number of catapult starts.

[0105] For example, the number of catapult starts is 350 times. After controlling the vehicle's catapult start according to the first power parameter, record one catapult start. Superimpose one catapult start on the basis of the number of catapult starts to obtain the superimposed number of catapult starts as 351 times, and update the stored number of catapult starts from 350 times to 351 times.

[0106] Through the above solution, after controlling the vehicle's catapult start according to the first power parameter, performing superposition processing on the number of catapult starts and this catapult start can obtain the superimposed number of catapult starts, and can update the stored number of catapult starts, so as to accurately judge whether the vehicle has been frequently using the catapult start function according to the number of catapult starts.

[0107] In some embodiments, the process of activating the catapult start function includes:

[0108] Step 1011, obtain the status information and gear information of the vehicle.

[0109] Step 1012, in response to determining that the status information is the stationary state and the gear position information is the drive gear position, obtain the braking force and the accelerator pedal opening of the vehicle.

[0110] Step 1013, in response to determining that the braking force is greater than a preset braking force threshold and the accelerator pedal opening is greater than a preset opening threshold, obtain the steering wheel angle.

[0111] Step 1014, in response to determining that the steering wheel angle is less than a preset angle threshold, compare the received power parameter with a preset power threshold.

[0112] Step 1015, in response to determining that the received power parameter is greater than the preset power threshold, activate the launch control function.

[0113] In specific implementation, the launch control system includes: a vehicle information acquisition module, a vehicle controller, a battery management system, and a motor control module. Among them, the vehicle information acquisition module acquires vehicle information and sends the vehicle information to the vehicle controller. The vehicle information includes: the status information, gear position information, braking force, accelerator pedal opening, and steering wheel angle of the vehicle. The vehicle controller includes launch control, storage of the number of launch controls, and vehicle controller torque request. The battery management system includes power control.

[0114] When the status information of the vehicle is the stationary state, the gear position information is the drive gear position, the braking force is greater than a preset braking force threshold, the accelerator pedal opening is greater than a preset opening threshold, and the steering wheel angle is less than a preset angle threshold, it is determined that the vehicle is in the starting state.

[0115] After determining that the vehicle is in the starting state, determine whether the start request is a launch control request. When the start request is a launch control request, activate the launch control function. Specifically, when the power system has no fault, compare the received power parameter with a preset power threshold. When the received power parameter is greater than the preset power threshold, it is determined that the start request is a launch control request, and the launch control function is activated.

[0116] In addition, in order to more accurately determine whether the start request is a launch control request, the specific determination process of the launch control request includes: obtaining the original power parameter sent by the battery management system and the target power parameter received by the vehicle controller; comparing the original power parameter with a preset first power threshold, and comparing the target power parameter with a preset second power threshold; in response to determining that the original power parameter is greater than or equal to the preset first power threshold and the target power parameter is greater than or equal to the preset second power threshold, it is determined that the start request is a launch control request, and the launch control function is activated.

[0117] Among them, the preset first power threshold is greater than the preset second power threshold. For example, the preset first power threshold is 200 N·m, and the preset second power threshold is 195 N·m. When the original power parameter sent by the battery management system is 200 N·m and the target power parameter received by the vehicle control unit is 196200 N·m, the launch control function is activated.

[0118] Through the above solution, when the state information of the vehicle is the stationary state, the gear information is the drive gear, the braking force is greater than the preset braking force threshold, the accelerator pedal opening is greater than the preset opening threshold, and the steering wheel angle is less than the preset angle threshold, it can be accurately determined that the vehicle is in the starting state. After determining that the vehicle is in the starting state, when the received power parameter is greater than the preset power threshold, it can be accurately determined that the starting request is a launch control request, thereby activating the launch control function.

[0119] Through the above embodiments, after the launch control function is activated, the number of launch controls is obtained, and the number of launch controls is compared with the preset number threshold. When the number of launch controls is less than the preset number threshold, the vehicle is controlled to perform a launch control according to the first power parameter, and the motor drive is controlled according to the first power parameter, which can ensure the normal use of the launch control function by the user. When the number of launch controls is greater than or equal to the preset number threshold, the vehicle is controlled to start according to the second power parameter; among them, both the first power parameter and the second power parameter are parameters for controlling the motor drive, and the second power parameter is less than the first power parameter. In this way, when the number of launch controls reaches the preset number threshold, the motor drive is controlled according to the second power parameter that is less than the first power parameter, which can control the vehicle to start with a larger driving force, and at the same time can avoid the situation of overheating of the power system caused by long-term and frequent use of the first power parameter to control the motor drive, realizing the protection of the power system.

[0120] It should be noted that the embodiments of the present disclosure can also be further described in the following manner:

[0121] Figure 3 is a schematic structural diagram of the launch control system according to the embodiment of the present disclosure. As Figure 3 shown, the launch control system includes: a vehicle information acquisition module, a vehicle control unit (abbreviated as VCU), a battery management system (abbreviated as BMS), and a motor control module.

[0122] Specifically, the vehicle information collected by the vehicle information collection module includes: vehicle speed information, gear position information, accelerator pedal status, brake pedal status, steering wheel angle, and powertrain failure. Power control mainly calculates the charge and discharge power of the battery system by the battery management system BMS based on the terminal voltage and current of the battery. The launch control module mainly controls the launch function by the vehicle control unit VCU according to the vehicle information collection signal and the BMS power. The storage of the number of launch starts mainly counts the vehicle after leaving the factory and stores the number of launch starts during the entire life cycle. The VCU torque request module calculates the VCU torque request and sends it to the motor control module through the CAN bus. The motor torque command makes the drive device operate, and a reduction gear with a fixed speed ratio is used between the motor and the drive wheels.

[0123] Figure 4 This is a flowchart of the launch control method according to an embodiment of the present disclosure. As Figure 4 shown, according to the collected vehicle information, it is determined that the vehicle is in a stationary state, in a drive gear, the brake pedal is depressed, the braking force is greater than a set braking force threshold (for example, 3500 N·m), at the same time the accelerator pedal is depressed, the accelerator pedal opening is greater than a set opening threshold (for example, 85%), and the steering wheel angle is small enough, there is no system failure and the powertrain performance reaches the maximum (calculated according to the battery charge and discharge power), then: activate the launch function. If the accelerator pedal is released within a set time (for example, 10 s) and the total number of launch starts is less than a set number threshold (for example, 500 times, the number threshold is calibrated according to the durability test of the powertrain experiment and the motor life evaluation), then the motor accelerates the vehicle according to the external characteristic curve 1 ( Figure 2 the curve 1 in Figure 2 ), such as: 200 KW / 340 Nm; if the total number of launch starts is greater than the set number threshold, the motor executes according to the external characteristic curve 2 (

[0124] the curve 2 in Figure 2 ), such as: 190 KW / 330 Nm. The external characteristic curve 1 of the motor sets the limit on the number of launches. After exceeding the number limit, it accelerates according to the external characteristic curve 2 of the motor. For the powertrain, the external characteristic curve 2 of the motor can ensure that the powertrain does not overheat and the key components such as the drive shaft and differential are within the effective protection range during long-term use of the launch start. Therefore, during the entire life cycle of the vehicle, by controlling the powertrain to execute different peak torques and peak powers, the purpose of not limiting the number of launch starts is achieved.

[0124] Specifically, in Figure 2In curve 1, the first motor speed threshold is the motor speed N1. When the current motor speed is less than or equal to the motor speed N1, the first preset torque Tmax1 is used as the first power parameter (first torque). When the current motor speed is greater than the motor speed N1, the first torque value corresponding to the current motor speed on curve 1 is used as the first power parameter (first torque). The first power parameter (first torque) is output to the motor, and the motor is controlled based on the first power parameter (first torque) to achieve the catapult start of the vehicle.

[0125] In Figure 2 In curve 2, the second motor speed threshold is the motor speed N2. When the current motor speed is less than or equal to the motor speed N2, the second preset torque Tmax2 is used as the second power parameter (second torque). When the current motor speed is greater than the motor speed N2, the second torque value corresponding to the current motor speed on curve 2 is used as the second power parameter (second torque). The second power parameter (second torque) is output to the motor, and the motor is controlled based on the second power parameter (second torque) to achieve the start of the vehicle.

[0126] In addition, it can be seen that Figure 2 when the current motor speeds are the same, the first power parameter corresponding to the first motor characteristic curve is less than the second power parameter corresponding to the second motor characteristic curve. In this way, when the number of catapult starts is less than the preset number threshold, the first power parameter (maximum power parameter) can be determined according to the first motor characteristic curve, and the vehicle is controlled to perform a catapult start according to the first power parameter, meeting the driving demand of the user to control the vehicle's catapult start; when the number of catapult starts is greater than or equal to the preset number threshold, the second power parameter (less than the first power parameter) can be determined according to the second motor characteristic curve, and the vehicle is controlled to start according to the second power parameter, while not affecting the vehicle's power system, maximizing the driving demand of the user to control the vehicle to start with a relatively large power.

[0127] Figure 5 This is a flowchart of the method for storing the number of catapult starts in an embodiment of the present disclosure. As Figure 5 shown, each time the catapult start is activated once, the number of catapult starts will be incremented by one, and so on. During the entire driving cycle of the vehicle, the number of catapult starts will be incrementally calculated, and the total number of catapult starts will be stored each time before the vehicle goes into hibernation. Therefore, starting from when the vehicle leaves the factory, the number of catapult starts will be counted and stored. By memorizing the number of catapult starts, the motor of the power system is then controlled to execute different external characteristic curves, realizing the protection of the power system.

[0128] Through the above embodiments, by storing and memorizing the number of times of performing a catapult start for a vehicle, setting a number threshold (for example, 500 times), within and outside the set threshold number of times, the torque peak and power of the electric drive system are executed according to different external characteristic curves, and the battery management system executes according to different powers respectively, enabling the user to frequently use the catapult start function, while realizing the protection of the power system, effectively enhancing the driving experience and driving pleasure of the vehicle, and meeting the requirements of high-performance vehicle owners.

[0129] It should be noted that the method of the embodiments of the present disclosure can be executed by a single device, such as a computer or a server, etc. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In such a distributed scenario, one of these multiple devices can only execute one or more steps of the method of the embodiments of the present disclosure, and these multiple devices will interact with each other to complete the described method.
