[0002] In the field of hybrid electric vehicles, planetary gear sets are widely used due to their efficient energy conversion and flexible power distribution characteristics. However, in vehicles equipped with planetary gear sets, during engine start-up, when braking is applied to the second motor (in addition to the starter motor), the effect of applying counter-braking torque varies depending on the position of the second motor in the gear set.

[0017] In some embodiments of this disclosure, the engine start-up requirement determination module is also specifically used to determine whether the vehicle has a target high-voltage device in operation. If it is determined that there is no target high-voltage device and the battery discharge power is less than or equal to the preset power threshold, it is determined that the battery discharge power does not meet the power requirements of the vehicle.

If the battery discharge power is less than or equal to the second power, it is determined that the battery discharge power does not meet the vehicle's power requirements.

[0018] In some embodiments of this disclosure, the vehicle's operating status information includes vehicle speed and gear information.

[0019] The vehicle start control device also includes a vehicle status determination module.

[0020] The vehicle status determination module is used to determine whether the vehicle speed is less than or equal to a preset vehicle speed threshold, and whether the first gear corresponding to the gear information is the target gear, including parking gear and neutral gear; When the vehicle speed is less than or equal to the preset vehicle speed threshold and the first gear is the target gear, the vehicle is determined to be in the preset state.

[0030] The technical solution provided in this disclosure has the following advantages: The vehicle starting control method, device, and vehicle provided in this disclosure can acquire vehicle operating status information in response to the vehicle meeting engine starting requirements. After acquiring the vehicle operating status information, the vehicle state is determined based on the vehicle operating status information. If the vehicle state is in a preset state, a compensation torque value for braking the wheels is determined. The preset state is used to characterize the vehicle in a non-driving state. Braking operation is performed on the vehicle wheels based on the chassis system and the compensation torque value to perform engine starting control. Thus, by directly applying a torque compensation value to the vehicle wheels to control the wheel-end torque output, the rotational tendency of the planetary gear set internal reaction force transmitted to the gear ring when the motor used as a starter drives the engine can be directly offset, forming a closed-loop feedback control. This reduces energy loss and response delay in intermediate transmission links and avoids relying on the braking torque of other motors besides the starter motor to indirectly constrain the gear ring movement. Its effect is limited by the motor position, gear ratio, and torque distribution logic. If the compensation torque does not match the actual reaction force, it can easily lead to over-braking (causing vibration) or under-braking (wheel micro-movement). Furthermore, by applying compensating torque to the wheels, it is possible to more efficiently isolate disturbances during engine startup, improve startup smoothness and system stability, and solve the problem of vehicle movement or vibration during engine startup.

[0034] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0038] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0039] In the field of hybrid electric vehicles, planetary gear sets are widely used due to their efficient energy conversion and flexible power distribution characteristics. However, in vehicles equipped with planetary gear sets, when the engine starts, the readiness indicator light on the dashboard illuminates, and the vehicle is in either Park (P) or Neutral (N). If all parameters monitored by the hybrid electronic control unit (ECU) are normal, the ECU will connect high-voltage electricity to motor 1, which acts as the starter motor to start the engine. During this process, the sun gear generates a reaction force when the engine starts. This reaction force might cause the ring gear of motor 2 to rotate, thus driving the wheels. To prevent the reaction force of the sun gear from rotating the ring gear of motor 2 and driving the wheels, the ECU controls the energization of motor 2 so that the rotation direction of the ring gear is opposite to the rotation direction generated by the sun gear. This is equivalent to applying braking; this function is called "reaction control." After starting, the planetary carrier becomes the driving element, and the sun gear becomes the driven element (because the vehicle is stationary). The planetary carrier drives the sun gear, and the engine charges the battery. However, during actual vehicle startup, when motor 1 starts and drives the engine, although motor 2 applies counter-braking torque, the effect of this torque application varies depending on the position of motor 2 in the power structure, and the starting torque also changes in real time. If the compensation torque of motor 2 cannot keep up in real time, it may over-compensate or under-compensate. When over-compensated, a larger torque than required to counteract the reaction force of the sun gear will be applied. This excessive torque will act in the opposite direction on the planetary gear system and then be transmitted to the wheels through the planetary gear power structure, causing unnecessary rotation of the vehicle and thus causing the vehicle to move. When under-compensated, the compensation torque cannot completely counteract the reaction force generated by the sun gear. At this time, the reaction force of the sun gear will act on the ring gear, thereby driving the wheels to rotate. At the same time, insufficient compensation will cause the power transmission within the planetary gear system to be uneven, and the coordination between the motion of various components will deteriorate, causing the vehicle to vibrate. Therefore, there is a problem of vehicle movement or vibration during engine startup. To address this problem, this disclosure provides a vehicle startup control method, which will be described below with reference to specific embodiments.

[0040] Figure 1 This is a flowchart of a vehicle start control method provided in an embodiment of the present disclosure. The method can be executed by a vehicle start control device, which can be implemented in software and / or hardware. The vehicle start control device can be configured in an electronic device, such as a server or terminal, wherein the terminal specifically includes an in-vehicle terminal, a computer or a tablet computer, etc.

[0041] like Figure 1 As shown, the vehicle start-up control method provided in this embodiment includes the following steps.

[0042] S110: In response to the vehicle meeting the engine start requirement, obtain the vehicle's operating status information.

[0043] In this embodiment of the disclosure, the vehicle is a hybrid vehicle. A hybrid vehicle is a car equipped with both an engine and an electric motor as power sources. Hybrid vehicles can intelligently switch power modes, exhibiting significant advantages in energy conservation and emission reduction, driving performance, and ease of use. For example, when the vehicle's battery charge is insufficient (i.e., the state of charge is too low), and / or, in specific scenarios when the battery cannot meet high power demands, the hybrid vehicle will start the engine to provide power to the vehicle.

[0044] In this embodiment of the disclosure, the vehicle's operating status information can be understood as a collection of information reflecting various performance parameters and environmental conditions of the vehicle during operation. Specifically, the operating status information may include vehicle speed, gear information, engine speed, engine coolant temperature, battery status information, and the vehicle's driving mode.

[0045] In this embodiment of the disclosure, the electronic device can obtain the vehicle's operating status information by controlling preset sensors in the vehicle to collect vehicle status information in response to the vehicle meeting the engine start-up requirements.

[0046] S120. Determine the vehicle's state based on the vehicle's operating status information. If the vehicle's state is in a preset state, determine the compensation torque value used for braking the wheels.

[0047] In this embodiment of the disclosure, the preset state is used to characterize that the vehicle is in a non-driving state.

[0048] In this embodiment of the disclosure, the vehicle being in a non-driving state can be understood as the vehicle's drive system not currently actively outputting power.

[0049] In this embodiment of the disclosure, after the electronic device obtains the vehicle's operating status information, it judges the vehicle's status based on the vehicle's operating status information to determine whether the vehicle is in a preset state. If it is determined that the vehicle is in a preset state, it determines the compensation torque value for braking the wheels based on the vehicle's operating status information.

[0050] S130 performs braking operations on the vehicle's wheels based on the chassis system and compensated torque values ​​to control engine start-up.

[0051] In this embodiment, the chassis system is one of the core structures of a vehicle, responsible for supporting the body, transmitting power, controlling driving, and ensuring vehicle safety and handling. Specifically, it may include a transmission system, a running system, a steering system, and a braking system. The transmission system primarily transmits the power generated by the engine to the drive wheels, propelling the vehicle. This system has functions such as deceleration, gear shifting, reversing, power interruption, inter-wheel differential, and inter-axle differential, ensuring normal vehicle operation under various conditions. The running system primarily converts the torque from the transmission system into traction force from the ground, withstands various external forces and torques on the vehicle, reduces vibration, mitigates impacts, and ensures normal and smooth vehicle operation. The steering system ensures the vehicle travels in the direction selected by the driver. The braking system includes a service brake system and a parking brake system, whose main functions are to decelerate and stop the vehicle, and ensure reliable parking.

[0052] In this embodiment of the disclosure, the electronic device can perform wheel operation based on braking system (such as electronic parking brake), hydraulic braking, or other methods.

[0053] In this embodiment of the disclosure, after obtaining the compensation torque value for braking the wheels, the electronic device can control the chassis system to perform the vehicle braking operation, so that the chassis system performs the braking operation on the vehicle wheels based on the compensation torque value, and applies braking force to the wheels corresponding to the compensation torque value, so as to control the engine starting process and avoid the vehicle from shaking or moving during the engine starting process.

[0054] In this embodiment, the vehicle's operating status information is acquired in response to the vehicle meeting the engine start-up requirement. After acquiring the vehicle's operating status information, the vehicle's state is determined based on the operating status information. If the vehicle's state is in a preset state, a compensation torque value for braking the wheels is determined. The preset state is used to characterize the vehicle as being in a non-driving state. Braking operations are performed on the vehicle's wheels based on the chassis system and the compensation torque value to control engine start-up. Thus, by directly applying a torque compensation value to the vehicle's wheels to control the wheel-end torque output, the rotational tendency of the planetary gear set's internal reaction force transmitted to the ring gear when the motor used as a starter drives the engine can be directly offset, forming a closed-loop feedback control. This reduces energy loss and response delay in intermediate transmission links and avoids relying on the braking torque of motors other than the starter motor to indirectly constrain the ring gear movement. The effect of this method is limited by the motor position, gear ratio, and torque distribution logic. If the compensation torque does not match the actual reaction force, it can easily lead to problems such as over-braking or under-braking. Furthermore, by applying compensating torque to the wheels, it is possible to more efficiently isolate disturbances during engine startup, improve startup smoothness and system stability, and solve the problem of vehicle movement or vibration during engine startup.

[0055] Based on the above embodiments of this disclosure, the electronic device can periodically or in real time detect whether the vehicle meets the engine starting requirements, or, after receiving an engine starting requirement detection command, detect whether the vehicle meets the engine starting requirements based on the engine starting requirement detection command to determine whether the vehicle meets the engine starting requirements.

[0056] The following will combine Figure 2 The specific implementation methods for determining whether the engine starting requirements are met are described in detail.

[0057] Figure 2 This is a flowchart of a method for determining engine start-up requirements provided in an embodiment of this disclosure, such as... Figure 2 As shown, determining whether a vehicle meets the engine starting requirements can include the following steps: S210: Obtain vehicle driving mode and battery status information.

[0058] In this embodiment of the disclosure, the driving mode of a vehicle can be understood as a function of the vehicle to adapt to different driving scenarios and driver needs by adjusting parameters such as power output, shift logic, steering feel, and suspension stiffness. For example, the driving modes of a vehicle may include economy mode, comfort mode, sport mode, off-road mode, snow mode, etc., and are not limited thereto.

[0059] In this embodiment of the disclosure, battery status information can be understood as key data reflecting the current operating status and health of the battery. Specifically, battery status information may include information such as battery state of charge, battery discharge power, battery temperature, battery voltage, and battery internal resistance.

[0060] In this embodiment of the disclosure, the electronic device can obtain the vehicle's driving mode by one or more of the following methods: obtaining the vehicle driving mode identification information, the icon or light display status corresponding to the vehicle driving mode, the parameter configuration corresponding to the vehicle driving mode, and engaging in voice interaction with the vehicle.

[0061] In this embodiment of the disclosure, the electronic device can collect battery status parameters in real time through the vehicle's preset sensors, thereby obtaining battery status information; it can also receive and read data sent by the battery management system through bus communication and other means, thereby obtaining battery status information; and it can also obtain battery status information through other means, which are not limited here.

[0062] S220 determines whether the vehicle meets the engine start-up requirements based on the vehicle's driving mode and battery status information.

[0063] In this embodiment of the disclosure, determining whether the vehicle meets the engine starting requirements based on vehicle driving mode and battery status information may specifically include: determining whether the vehicle driving mode is a target driving mode, whether the battery state of charge is less than or equal to a preset state of charge threshold, and whether the battery discharge power meets the vehicle power requirements; if the vehicle driving mode is the target driving mode, the battery state of charge is less than or equal to the preset state of charge threshold, and the battery discharge power does not meet the vehicle power requirements, then the engine starting requirements are met; if the vehicle driving mode is a non-target driving mode, and / or the battery state of charge is greater than the preset state of charge threshold, and / or the battery discharge power meets the vehicle power requirements, then the engine starting requirements are not met.

[0064] In this embodiment of the disclosure, the target driving mode can be understood as the driving mode of the vehicle when power is required solely by the engine, or when power is required to be provided by the engine and electric motor working together. For example, the target driving mode may include Sport mode, Snow mode, Off-road mode, etc.

[0065] In this embodiment of the disclosure, the preset state of charge threshold can be understood as a pre-set state of charge threshold used to characterize the state of charge when the battery power is insufficient.

[0066] Specifically, after acquiring the vehicle's driving mode and battery status information, the electronic device determines whether the vehicle's driving mode is the target driving mode, whether the battery's state of charge is less than or equal to a preset state of charge threshold, and whether the battery's discharge power meets the vehicle's power requirements to determine whether the engine starting requirements are met.

[0067] In some embodiments of this disclosure, when the electronic device determines that the vehicle driving mode is the target driving mode, the battery state of charge is less than or equal to a preset state of charge threshold, and the battery discharge power does not meet the vehicle power requirements, it indicates that the vehicle needs to start the engine to provide power to the vehicle, and thus determines that the current state of the vehicle meets the engine starting requirements.

[0068] In other embodiments of this disclosure, the electronic device determines that the engine starting requirement is not met if any one or more of the following conditions are met: the vehicle driving mode is a non-target driving mode, the battery state of charge is greater than a preset state of charge threshold, or the battery discharge power meets the vehicle power requirements.

[0069] In this embodiment, the vehicle's driving mode, battery state of charge, and battery discharge power are comprehensively considered to determine whether the engine starting requirements are met. This improves the accuracy of engine starting timing and avoids power interruption caused by low battery state of charge or insufficient discharge power, ensuring vehicle performance and driving stability. Simultaneously, it prevents over-discharge of the battery, which could damage battery life. A balance is achieved between powertrain efficiency, driving experience, and component protection.

[0070] In this embodiment of the disclosure, determining whether the battery discharge power meets the vehicle power requirements may specifically include: determining whether the vehicle has a target high-voltage device in operation; if it is determined that there is no target high-voltage device and the battery discharge power is less than or equal to a preset power threshold, determining that the battery discharge power does not meet the vehicle power requirements; if it is determined that there is a target high-voltage device, obtaining a first power corresponding to the target high-voltage device, and determining a second power based on the first power and the preset power threshold; if the battery discharge power is less than or equal to the second power, determining that the battery discharge power does not meet the vehicle power requirements.

[0071] In this embodiment of the disclosure, the target high-voltage device can be understood as a device powered by high-voltage electricity. For example, the target high-voltage device may include an air conditioner, a heater, etc.

[0072] In this embodiment of the disclosure, the preset power threshold is a pre-set lower limit of power required to meet the power demand of the entire vehicle when no high-voltage devices are operating.

[0073] Specifically, if the electronic device does not have a target high-voltage device and the battery discharge power is less than or equal to a preset power threshold, it indicates that the battery discharge power cannot meet the vehicle's power requirements. If the battery discharge power is greater than the preset power threshold, it indicates that the battery discharge power can meet the vehicle's power requirements. If a target high-voltage device is present, the first power corresponding to the target high-voltage device is obtained. The first power is added to the preset power threshold to obtain a second power. The second power is compared with the battery discharge power. If the battery discharge power is less than or equal to the second power, it is determined that the battery discharge power does not meet the vehicle's power requirements. If the battery discharge power is greater than the second power, it is determined that the battery discharge power meets the vehicle's power requirements.

[0074] In this embodiment, when determining whether the battery discharge power meets the vehicle's power requirements, the operating high-voltage devices are taken into account. By monitoring the power consumption of each high-voltage device in real time, the current total load demand can be accurately calculated, avoiding the problem of underestimating the actual power, which could lead to over-discharge of the battery or insufficient power, thus affecting vehicle performance and causing misjudgment. Therefore, the accuracy of determining whether the battery discharge power meets the vehicle's power requirements is improved.

[0075] In this embodiment of the disclosure, the vehicle's speed and gear information can be used to determine whether the vehicle is in a preset state, thereby improving the accuracy of vehicle state determination.

[0076] In this embodiment of the disclosure, the vehicle's operating status information may include vehicle speed and gear information.

[0077] Determining whether the vehicle is in a preset state can specifically include: determining whether the vehicle speed is less than or equal to a preset speed threshold and whether the first gear corresponding to the gear information is the target gear; if the vehicle speed is less than or equal to the preset speed threshold and the first gear is the target gear, determining that the vehicle is in a preset state; if the vehicle speed is greater than the preset speed threshold and / or the first gear is not the target gear, determining that the vehicle is not in a preset state.

[0078] In this embodiment of the disclosure, the target gears include Park (P) and Neutral (N).

[0079] In this embodiment of the disclosure, the preset vehicle speed threshold can be understood as a vehicle speed threshold used to characterize a vehicle when it is stationary. For example, the preset vehicle speed threshold can be 2 kilometers per hour.

[0080] Specifically, after acquiring the vehicle's operating status information, the electronic device compares the vehicle speed with a preset speed threshold to determine whether the vehicle speed is less than or equal to the preset speed threshold. At the same time, it determines whether the first gear corresponding to the gear information is the target gear, i.e., whether it is P gear or N gear. If the vehicle speed is less than or equal to the preset speed threshold and the first gear is the target gear, then the vehicle is determined to be in a stationary state, i.e., the preset state. If the vehicle speed is greater than the preset speed threshold and / or the first gear is not the target gear, then the vehicle is determined to be not in the preset state.

[0081] In this embodiment, when the vehicle meets the engine starting requirements, it can determine whether the vehicle is in a preset state based on the vehicle speed and gear information. This ensures that the engine is started in a non-driving state, keeping the vehicle stationary during engine starting and guaranteeing engine starting safety. It also avoids power conflicts caused by misoperation during engine starting. Simultaneously, it allows the engine to operate at a low load initially, gradually warming up to its optimal operating temperature, thus extending engine life.

[0082] In this embodiment of the disclosure, determining the compensation torque value for braking the wheels may specifically include: acquiring engine status information; determining the target torque value applied to the target motor based on the engine status information; and determining the compensation torque value based on the target torque value and the transmission ratio.

[0083] In this embodiment of the disclosure, engine status information may include engine speed and engine coolant temperature.

[0084] In this embodiment of the disclosure, the target motor is a motor used to start the engine.

[0085] Specifically, when the vehicle is in a preset state, the electronic device can collect engine status information based on the target sensor, and then obtain the engine status information in real time, namely engine speed and engine coolant temperature. Based on the preset correspondence between engine speed and engine coolant temperature and torque, the target torque value applied to the target motor is determined, and the target torque value is multiplied by the transmission ratio to obtain the compensation torque value.

[0086] In this embodiment, the engine's real-time operating condition can be directly reflected based on the engine speed and engine coolant temperature. The motor torque value can then be dynamically adjusted based on the engine's real-time operating condition. By introducing a transmission ratio based on the motor torque value, the matching of torque output is ensured, preventing energy waste or mechanical shock caused by torque transmission mismatch. This optimizes the vehicle's energy efficiency, extends the life of the transmission system, and improves the vehicle's smoothness, economy, and reliability.

[0087] In this embodiment of the disclosure, after performing braking operations on the vehicle's wheels based on the chassis system and the compensation torque value, the vehicle start control method may further include: acquiring the vehicle's wheel braking force; and, if it is determined that the wheel braking force is greater than a preset braking force threshold, performing an engine start operation.

[0088] In this embodiment of the disclosure, the preset braking force threshold can be understood as a braking force threshold used to characterize the initial torque required to meet the engine starting requirements.

[0089] Specifically, the electronic device can collect the vehicle's wheel braking force in real time based on preset wheel braking force sensors, compare the wheel braking force with a preset braking force threshold, and execute the engine start operation if it is determined that the wheel braking force is greater than the preset braking force threshold.

[0090] In this embodiment of the disclosure, the engine start-up can be determined by the wheel braking force. That is, by accurately matching the braking demand with the power system status, the accuracy and smoothness of engine start-up are ensured. At the same time, by the intervention of the engine, part of the braking load is shared, reducing friction braking heat loss and extending the battery charging cycle.

[0091] In this embodiment of the disclosure, after the engine start operation is performed, the vehicle start control method may further include: obtaining the target speed corresponding to the engine, and / or the target gear information of the vehicle; when the target speed reaches a preset speed threshold and continues for a preset duration, and / or when the second gear corresponding to the target gear information is a non-target gear, setting the compensation torque value applied to the wheels to zero.

[0092] In this embodiment of the disclosure, the second gear may include forward gear, reverse gear, etc.

[0093] In this embodiment of the disclosure, the engine's target speed reaching a preset speed threshold and lasting for a preset duration can be understood as the engine being in an idling state, i.e., the engine has been started.

[0094] In this embodiment of the disclosure, when the engine speed reaches a stable operating range and a preset speed threshold is reached, and its own power output is sufficient to meet the driving requirements, canceling the compensation torque applied to the wheels can avoid excessive wheel torque caused by power superposition. At the same time, it can also reduce the energy loss caused by frequent motor intervention, extend the life of the motor and battery, and reduce the impact of sudden torque changes in the transmission system.

[0095] Figure 3 This is a flowchart of another vehicle start control method provided in this disclosure embodiment, such as... Figure 3 As shown, the vehicle start-up control method may include the following steps: S310: In response to the vehicle meeting the engine start requirement, obtain the vehicle's operating status information.

[0096] S320. Determine the vehicle's state based on the vehicle's operating status information. If the vehicle's state is in a preset state, determine the compensation torque value used for braking the wheels.

[0097] The S330 performs braking operations on the vehicle's wheels based on the chassis system and compensated torque values.

[0098] S340: Obtain the wheel braking force of the vehicle, and if it is determined that the wheel braking force is greater than the preset braking force threshold, execute the engine start operation.

[0099] S350: Obtain the target speed corresponding to the engine and / or the target gear information of the vehicle. When the target speed reaches the preset speed threshold and continues for a preset duration, and / or when the second gear corresponding to the target gear information is not the target gear, set the compensation torque value applied to the wheels to zero.

[0100] It should be noted that the specific implementation methods of steps S310 to S350 are similar to those of the relevant steps in the above embodiments of this disclosure, and will not be repeated here.

[0101] In this embodiment, the torque output at the wheel end can be controlled by directly applying a torque compensation value to the vehicle's wheels. This directly counteracts the rotational tendency of the planetary gear set's internal reaction force transmitted to the ring gear when the motor used as a starter drives the engine, forming a closed-loop feedback control. This reduces energy loss and response delay in intermediate transmission links and avoids relying on the braking torque of motors other than the starter motor to indirectly constrain the ring gear's movement. The effectiveness of this approach is limited by the motor position, gear ratio, and torque distribution logic. If the compensation torque does not match the actual reaction force, it can easily lead to over-braking or under-braking. Furthermore, applying compensation torque to the wheels can more efficiently isolate disturbances during engine startup, improving startup smoothness and system stability, and solving the problem of vehicle movement or vibration during engine startup. At the same time, by precisely matching braking demand and power system status, the accuracy and smoothness of engine startup are ensured. When the engine speed reaches a stable operating range, i.e., a preset speed threshold, and its own power output is sufficient to meet the driving demand, canceling the compensation torque applied to the wheels avoids excessive wheel torque caused by power superposition, ensuring smooth power response while improving system efficiency and reliability.

[0102] Figure 4 This is a schematic diagram of the structure of a vehicle start control device provided in an embodiment of this disclosure.

[0103] In this embodiment, the vehicle start control device can be housed within an electronic device and is understood as a functional module within the aforementioned electronic device. Specifically, the electronic device can be a server or a terminal, wherein the terminal specifically includes an in-vehicle terminal, a computer, or a tablet computer, etc., without limitation.

[0104] like Figure 4 As shown, the vehicle start control device 400 may include an information acquisition module 410, a compensation torque determination module 420, and an engine start control module 430.

[0105] The information acquisition module 410 can be used to acquire the vehicle's operating status information in response to the vehicle meeting the engine start-up requirements; The compensation torque determination module 420 can be used to determine the state of the vehicle based on the vehicle's operating state information. When the vehicle is in a preset state, it determines the compensation torque value for braking the wheels. The preset state is used to characterize the vehicle as being in a non-driving state. The engine start control module 430 can be used to perform braking operations on the vehicle's wheels based on the chassis system and the compensation torque value in order to control engine start.

[0106] In this embodiment, the vehicle's operating status information is acquired in response to the vehicle meeting the engine start-up requirement. After acquiring the vehicle's operating status information, the vehicle's state is determined based on the operating status information. If the vehicle's state is in a preset state, a compensation torque value for braking the wheels is determined. The preset state is used to characterize the vehicle as being in a non-driving state. Braking operations are performed on the vehicle's wheels based on the chassis system and the compensation torque value to control engine start-up. Thus, by directly applying a torque compensation value to the vehicle's wheels to control the wheel-end torque output, the rotational tendency of the planetary gear set's internal reaction force transmitted to the ring gear when the motor used as a starter drives the engine can be directly offset, forming a closed-loop feedback control. This reduces energy loss and response delay in intermediate transmission links and avoids relying on the braking torque of other motors besides the starter motor to indirectly constrain the ring gear movement. The effect of this is limited by the motor position, gear ratio, and torque distribution logic. If the compensation torque does not match the actual reaction force, it can easily lead to over-braking (causing vibration) or under-braking (wheel micro-movement). Furthermore, by applying compensating torque to the wheels, it is possible to more efficiently isolate disturbances during engine startup, improve startup smoothness and system stability, and solve the problem of vehicle movement or vibration during engine startup.

[0107] In some embodiments of this disclosure, the vehicle start control device 400 may further include an engine start demand determination module.

[0108] The engine start-up requirement determination module can be used to obtain vehicle driving mode and battery status information; The system determines whether the vehicle meets the requirements for starting the engine based on the vehicle's driving mode and battery status information.

[0109] In some embodiments of this disclosure, battery state information includes battery state of charge and battery discharge power.

[0110] The engine start demand determination module can be specifically used to determine whether the vehicle driving mode is the target driving mode, whether the battery state of charge is less than or equal to the preset state of charge threshold, and whether the battery discharge power meets the vehicle power requirements. When the vehicle driving mode is the target driving mode, the battery state of charge is less than or equal to the preset state of charge threshold, and the battery discharge power does not meet the vehicle power requirements, the engine starting requirements are determined to be met. If the vehicle driving mode is a non-target driving mode, and / or the battery state of charge is greater than the preset state of charge threshold, and / or the battery discharge power meets the vehicle power requirements, it is determined that the engine starting requirement is not met.

[0111] In some embodiments of this disclosure, the engine start-up requirement determination module may also be specifically used to determine whether the vehicle has a target high-voltage device in operation. If it is determined that there is no target high-voltage device and the battery discharge power is less than or equal to the preset power threshold, it is determined that the battery discharge power does not meet the power requirements of the vehicle. If the existence of a target high-voltage device is confirmed, the first power corresponding to the target high-voltage device is obtained, and the second power is determined based on the first power and a preset power threshold. If the battery discharge power is less than or equal to the second power, it is determined that the battery discharge power does not meet the vehicle's power requirements.

[0112] In some embodiments of this disclosure, the vehicle's operating status information includes vehicle speed and gear information.

[0113] The vehicle start control device 400 may also include a vehicle status determination module.

[0114] The vehicle status determination module can be used to determine whether the vehicle speed is less than or equal to a preset vehicle speed threshold, and whether the first gear corresponding to the gear information is the target gear, including parking gear and neutral gear; When the vehicle speed is less than or equal to the preset vehicle speed threshold and the first gear is the target gear, the vehicle is determined to be in the preset state. If the vehicle speed exceeds the preset speed threshold and / or the first gear is not the target gear, it is determined that the vehicle is not in the preset state.

[0115] In some embodiments of this disclosure, the compensation torque determination module 420 can be specifically used to obtain engine status information, including engine speed and engine coolant temperature. The target torque value applied to the target motor is determined based on the engine status information. The target motor is the motor used to start the engine. The compensation torque value is determined based on the target torque value and the transmission ratio.

[0116] In some embodiments of this disclosure, the vehicle start control device 400 may further include an engine start module.

[0117] The engine start module can be used to obtain the wheel braking force of the vehicle after braking operations are performed on the vehicle's wheels based on the chassis system and the compensation torque value. If the braking force of the wheels is determined to be greater than the preset braking force threshold, the engine is started.

[0118] In some embodiments of this disclosure, the vehicle start control device 400 may further include a torque compensation value adjustment module.

[0119] The torque compensation adjustment module can be used to obtain the target engine speed and / or the target gear information of the vehicle after the engine start operation is performed. When the target speed reaches the preset speed threshold and continues for a preset duration, and / or when the second gear corresponding to the target gear information is a non-target gear, the compensation torque value applied to the wheel will be set to zero.

[0120] It should be noted that, Figure 4 The vehicle start control device 400 shown can execute the various steps in the above method embodiments and achieve the various processes and effects in the above method embodiments, which will not be elaborated here.

[0122] In this embodiment of the disclosure, Figure 5 The electronic device shown can be a server or a terminal. Specifically, the terminal includes in-vehicle terminals, computers, or tablets, etc., without limitation.

[0123] like Figure 5 As shown, the electronic device may include a processor 510 and a memory 520 storing computer program instructions.

[0124] Specifically, the processor 510 may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits that can be configured to implement the embodiments of this disclosure.

[0125] Memory 520 may include a large-capacity storage device for information or instructions. For example, and not limitingly, memory 520 may include a hard disk drive (HDD), a floppy disk drive, flash memory, optical disk, magneto-optical disk, magnetic tape, or a Universal Serial Bus (USB) drive, or a combination of two or more of these. Where appropriate, memory 520 may include removable or non-removable (or fixed) media. Where appropriate, memory 520 may be internal or external to the integrated gateway device. In a particular embodiment, memory 520 is a non-volatile solid-state memory. In a particular embodiment, memory 520 includes read-only memory (ROM). Where appropriate, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (Electrically Programmable ROM, EPROM), an electrically erasable programmable PROM (EEPROM), an electrically alterable ROM (EAROM), or flash memory, or a combination of two or more of these.

[0126] The processor 510 reads and executes computer program instructions stored in the memory 520 to perform the steps of the vehicle start control method provided in this embodiment of the present disclosure.

[0127] In one example, the electronic device may also include a transceiver 530 and a bus 540. Wherein, as... Figure 5 As shown, the processor 510, memory 520 and transceiver 530 are connected via bus 540 and communicate with each other.

[0128] Bus 540 may include hardware, software, or both. For example, and not limitingly, the bus may include an Accelerated Graphics Port (AGP) or other graphics bus, an Extended Industry Standard Architecture (EISA) bus, a Front Side Bus (FSB), a Hyper Transport (HT) interconnect, an Industrial Standard Architecture (ISA) bus, an Infinite Bandwidth Interconnect, a Low Pin Count (LPC) bus, a memory bus, a MicroChannel Architecture (MCA) bus, a Peripheral Component Interconnect (PCI) bus, a PCI-Express (PCI-X) bus, a Serial Advanced Technology Attachment (SATA) bus, a Video Electronics Standards Association Local Bus (VLB) bus, or other suitable buses, or a combination of two or more of these. Where appropriate, bus 540 may include one or more buses.

[0129] This disclosure also provides a computer-readable storage medium that can store a computer program that, when executed by a processor, enables the processor to implement the vehicle start control method provided in this disclosure.

[0130] When the computer program is executed by the processor, the processor performs the following steps: in response to the vehicle meeting the engine start requirement, it acquires the vehicle's operating status information; based on the vehicle's operating status information, it determines the vehicle's state; if the vehicle's state is in a preset state, it determines the compensation torque value for braking the wheels, the preset state being used to characterize the vehicle being in a non-driving state; and based on the chassis system and the compensation torque value, it performs braking operations on the vehicle's wheels to control engine start.

[0131] The system can respond to the vehicle's engine starting requirements by acquiring the vehicle's operating status information. After acquiring this information, it determines the vehicle's state. If the vehicle is in a preset state, it determines a compensation torque value for braking the wheels. This preset state indicates the vehicle is in a non-drive state. Based on the chassis system and the compensation torque value, it performs braking operations on the vehicle's wheels to control engine starting. Therefore, by directly applying a torque compensation value to the vehicle's wheels to control the wheel-end torque output, it can directly counteract the rotational tendency of the planetary gear set's internal reaction force transmitted to the ring gear when the motor (acting as a starter) drives the engine. This forms a closed-loop feedback control, reducing energy loss and response delay in intermediate transmission links. It avoids relying on the braking torque of motors other than the starter motor to indirectly constrain the ring gear's movement. The effectiveness of this approach is limited by motor position, gear ratio, and torque distribution logic. If the compensation torque does not match the actual reaction force, it can easily lead to over-braking (causing vibration) or under-braking (wheel micro-movement). Furthermore, by applying compensating torque to the wheels, it is possible to more efficiently isolate disturbances during engine startup, improve startup smoothness and system stability, and solve the problem of vehicle movement or vibration during engine startup.
