[0020] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] In the related art, in traditional hybrid vehicles, the switching of driving modes is mainly carried out automatically based on vehicle speed and driving needs. For example, in snow mode, when the vehicle speed exceeds 30 km / h, the direct drive mode is usually adopted, that is, the engine directly drives the vehicle; and when the vehicle speed is lower than 30 km / h, it switches to Eidle mode, that is, the engine idles, the clutch is open, and the front and rear motors provide pure electric drive. Although this mode switching can cope with different road conditions, there are some defects in actual use. In winter snow mode, if the vehicle is driven at a low speed for a long time, the vehicle will continue to be in Eidle mode, which will cause continuous power consumption, thereby affecting the vehicle's endurance. In this case, users may feel inconvenienced by frequent low-battery warnings, causing customer complaints. In traditional systems, the application scenarios of low-speed direct drive are limited and can only be started at a specific vehicle speed, which limits the application of direct drive mode under low-speed conditions and reduces the flexibility and adaptability of driving.

[0023] Based on the above problems, the applicant found that: in response to determining that the current driving mode of the vehicle is the target driving mode, the vehicle's operating data is obtained; in response to determining that the operating data meets the slip-friction direct drive condition, it is determined whether the current vehicle speed is within the target vehicle speed range; in response to determining that the vehicle speed is within the target vehicle speed range, the vehicle's clutch is controlled to switch from the current state to the slip-friction state. It is possible to expand the speed range of direct drive, reduce the reliance on pure electric driving, and simplify the switching process between modes, so as to improve the performance of the vehicle in snow mode and user satisfaction.

[0024] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] The present application provides a vehicle control method, such as Figure 1As shown, in some embodiments, the method is executed by a vehicle controller or a data processor independently provided by the vehicle controller. The subsequent embodiments are all illustrated by taking the vehicle controller as an example; the method includes:

[0026] S101, in response to determining that the current driving mode of the vehicle is the target driving mode, acquiring operation data of the vehicle;

[0027] During specific implementation, the driving mode in which the vehicle is set is detected and confirmed, such as economic mode, sports mode, snow mode, etc. Different driving modes may require different control strategies and parameter settings. Once the vehicle's driving mode is determined to be the target driving mode (for example, snow mode), the vehicle's operating data is obtained. The operating data may include but is not limited to vehicle speed, engine speed, power battery power, activation status of the vehicle's electronic stability system, etc. The operating data will be used to evaluate the current operating status of the vehicle and serve as a basis for decision-making.

[0028] S102, in response to determining that the operating data satisfies the sliding friction direct drive condition, determining whether the current vehicle speed is within a target vehicle speed range;

[0029] In specific implementation, the operating data usually includes the power of the vehicle's power battery and the activation status of the vehicle's electronic stability system. If it is determined that the power of the vehicle's power battery is less than or equal to the preset power (for example, the preset power is set to 40%), it indicates that the vehicle's power is too low and the power battery cannot provide power for a long time; and the vehicle's electronic stability system is in an inactive state, indicating that the vehicle is in a relatively stable driving state, and the current driving conditions allow some adjustments to the power transmission mode. Therefore, it can be determined that the operating data meets the sliding direct drive condition, then it is determined whether the vehicle's current speed is within the target speed range, and the target The target speed range is pre-set and defines the speed range in which the slipping direct drive mode can operate effectively. When the vehicle speed is below the upper limit of the target speed range, the vehicle switches to motor-driven vehicle, consuming power from the power battery. When the vehicle's clutch is controlled to switch from the current state to the slipping state, the vehicle is driven by the engine to save more power. When the clutch is in the slipping state, the minimum speed to ensure normal driving of the vehicle is the lower limit of the target speed range. Usually the target speed range is between 15 and 30 kilometers per hour. When it is determined that the operating data meets the slipping direct drive conditions, it will be checked whether the current speed is within this range.

[0030] S103: In response to determining that the vehicle speed is within the target vehicle speed range, control the clutch of the vehicle to switch from a current state to a slipping state.

[0031] In specific implementation, when it is determined that the vehicle speed is within the target speed range (for example, the target speed range can be set to 15 to 30 kilometers per hour), the clutch of the vehicle is controlled to switch from the current state to the slip state. The slip state is a special clutch working state, in which the clutch is neither fully engaged nor fully disconnected, but is in a state that allows the clutch disc to slide slightly. This state allows partial torque to be transmitted between the engine and the drive wheel, while also absorbing some vibrations and noise during the power transmission process, thereby providing a smoother acceleration feeling and a more comfortable driving experience. The process of controlling the clutch to switch to the slip state usually involves sending a control signal according to the real-time data of the vehicle and the preset parameters, adjusting the working state of the clutch, and also accurately adjusting the pressure of the clutch to ensure that the clutch is in the correct slip position, neither fully engaged nor fully separated. By setting the clutch in the slip state, the speed range of the vehicle driven by the engine can be expanded, the dependence on pure electric driving can be reduced, and the vehicle's endurance and user satisfaction in the snow mode can be improved. At the same time, a smoother and more powerful driving experience is provided.

[0032] In this embodiment, when it is determined that the operating data meets the slipping direct drive condition and the vehicle speed is within the target speed range, the clutch of the vehicle is controlled to switch from the current state to the slipping state. In the slipping state, the clutch allows partial torque transmission between the engine and the drive system. This partial torque transmission helps the vehicle to drive safely on slippery roads, while reducing battery consumption, especially when the battery power is low, the engine power can be effectively utilized to extend the battery life and the vehicle's driving distance. The slipping state can provide a smoother acceleration experience. Since the clutch is not fully engaged, it can absorb part of the vibration and noise in the power transmission process while transmitting torque, thereby reducing the bumps and noise during driving and making driving more comfortable.

[0033] In some embodiments, controlling the clutch of the vehicle to switch from a current state to a slipping state includes:

[0034] In response to determining that the current state is the disconnected state, controlling the clutch of the vehicle to switch from the disconnected state to the slipping state;

[0035] In specific implementation, it is first necessary to identify the current state of the clutch, and if it is determined that the current state is the disconnected state, the clutch of the vehicle is controlled to switch from the disconnected state to the slipping state. The disconnected state of the clutch indicates that the clutch is completely separated, which usually occurs when the vehicle is stopped or in certain driving modes, such as in pure electric drive mode, where there is no direct physical connection between the engine and the drive system. When it is confirmed that the clutch is in the disconnected state, the clutch is controlled to switch from the disconnected state to the slipping state. In the slipping state, the clutch allows a certain degree of torque transmission, which helps to reduce battery consumption.

[0036] In response to determining that the current state is the engaged state, determining a current drive mode of the vehicle;

[0037] In a specific implementation, the current state is determined to be the engaged state, indicating that the clutch is fully engaged. In this state, the vehicle is usually in a conventional direct drive mode or a series mode. In the direct drive mode, the engine directly drives the vehicle, while in the series mode, such as Figure 2 As shown, the engine will drive the front motor to generate electricity, and the rear motor will drive the vehicle. If the current state is determined to be the engaged state, it is necessary to further determine the current driving mode of the vehicle. If the vehicle is in direct drive mode, the clutch can be directly switched from the engaged state to the slipping state. However, if the vehicle is switched to the slipping direct drive mode in the series mode, it is necessary to control the clutch of the vehicle to switch from the engaged state to the disconnected state, and then control the clutch to switch from the disconnected state to the slipping state. Therefore, when it is determined that the current state is the engaged state, it is necessary to determine the current driving mode of the vehicle.

[0038] In response to determining that the current driving mode is the direct drive mode, controlling a clutch of the vehicle to switch from the engaged state to a slipping state;

[0039] In specific implementation, when it is determined that the current driving mode is the direct drive mode, it indicates that the vehicle mainly relies on the engine to provide power, and the clutch is in a fully engaged state, ensuring that the power of the engine can be directly transmitted to the drive wheels. At this time, the clutch can be directly adjusted from the engaged state to the slipping state. The slipping state is an intermediate state, where the clutch is neither fully engaged nor fully disengaged, allowing the clutch to produce a slight slip during rotation, which can help to smoothly adjust the torque output, help the vehicle to drive safely at low speeds on slippery roads, and reduce battery consumption.

[0040] In response to determining that the current driving mode is the series mode, the clutch of the vehicle is controlled to switch from the engaged state to the disconnected state, and then the clutch is controlled to switch from the disconnected state to the slipping state, so that the driving mode of the vehicle is switched to the slipping direct drive mode.

[0041] In specific implementation, in series mode, the engine usually does not directly drive the wheels, but drives the motor to generate electricity. The clutch is usually in a coupled state in this mode to ensure that the engine can effectively transmit power for power generation. At this time, it is necessary to switch the clutch from the coupled state to the fully disconnected state, and then control the clutch to switch from the disconnected state to the slipping state, so that the vehicle's drive mode is switched to the slipping direct drive mode. This helps the vehicle to drive safely at low speed on slippery roads, while reducing battery consumption.

[0042] In this embodiment, adjusting the clutch from the engaged state to the slipping state can help to smoothly adjust the torque output and reduce the bumps and vibrations that may occur during the driving process. In the slipping state, the clutch allows slight sliding, which can provide better control on wet or uneven roads, reduce the risk of slipping, and enhance driving safety. In the series mode, switching the clutch from the engaged state to the disconnected state and then to the slipping state can ensure that the vehicle can safely and smoothly switch the drive mode to the slipping direct drive mode. This helps the vehicle to drive safely at low speed on wet roads and can reduce battery consumption.

[0043] In some embodiments, after controlling the clutch of the vehicle to switch from the current state to the slip state, the method further includes:

[0044] In response to receiving a switching instruction to switch the vehicle to the series mode, the clutch is switched from the slip state to the disconnected state, and then the clutch is switched from the disconnected state to the engaged state, so that the vehicle is in the series mode.

[0045] In specific implementation, when a switching instruction to switch the vehicle to the series mode is received, the clutch is first adjusted from the slipping state to the completely disconnected state. In the slipping state, the clutch is partially engaged, allowing a certain degree of torque transmission and slipping. In the series mode, the engine usually does not directly drive the wheels, but is used to provide power to the motor or charge the battery. After the clutch is completely disconnected, the clutch is further controlled to transition from the disconnected state to the fully engaged state, and the vehicle is thus switched from the slipping direct drive mode to the series mode. The engine can directly transfer power to the motor through the clutch for power generation, thereby realizing the working principle of the series mode. If the slipping state is directly switched to the engaged state, since the engine generates a large torque in the series mode, and the clutch cannot be switched to the engaged state (overpressure state) in time, causing the engine to spin fast, so the clutch of the vehicle is first controlled to switch from the slipping state to the disconnected state, and then the clutch is controlled to switch from the disconnected state to the engaged state, which can ensure that the vehicle safely and smoothly switches the drive mode to the series mode.

[0046] In this embodiment, by first switching the clutch from the slipping state to the disconnected state and then switching it to the engaged state, the possible engine runaway caused by switching directly from the slipping state to the engaged state can be avoided. This gradual transition helps to smoothly adjust the power system and reduce the pressure and potential damage to mechanical components. In the slipping state, the clutch is not completely disconnected. If it is directly switched to the engaged state, the engine may run away due to sudden load changes, which will not only cause damage to the engine and clutch, but also may cause instability in vehicle control. By disconnecting the clutch first, it can be ensured that the engine smoothly transitions to the engaged state without load. Ensuring that the clutch state is switched correctly can avoid vehicle loss of control due to sudden changes in the power system during driving. This is crucial to ensure the safety of drivers and passengers.

[0047] In some embodiments, after controlling the clutch of the vehicle to switch from the current state to the slip state, the method further includes:

[0048] In response to determining that the vehicle speed is outside the target vehicle speed interval, the clutch is controlled to switch from the slipping state to a disengaged state or an engaged state according to the vehicle speed.

[0049] In specific implementation, after the clutch of the vehicle is controlled to switch from the current state to the slipping state, the real-time speed of the vehicle is still monitored. When it is determined that the vehicle speed is outside the target speed range, if the clutch is still in the slipping state, it may cause insufficient vehicle power or other driving problems. Therefore, when it is determined that the vehicle speed is outside the target speed range, the clutch is controlled to switch from the slipping state to the disconnected state or the engaged state according to the vehicle speed to ensure more stable and continuous power output and adapt to new driving needs.

[0050] In this embodiment, when the vehicle speed exceeds the target speed range of the predetermined slip-friction direct drive mode, maintaining the clutch in the slip-friction state may result in insufficient or excessive power transmission efficiency, thereby affecting the acceleration performance and fuel efficiency of the vehicle. Timely adjustment of the clutch to the engaged state or the disengaged state can ensure that the output of the engine and the motor better matches the current speed requirements, thereby improving the overall driving responsiveness and power efficiency. Proper clutch control can reduce the bumps and instability that may be caused by using the slip-friction state at an inappropriate vehicle speed. For example, when driving at high speed, if the clutch is still in the slip-friction state, it may cause the vehicle to accelerate discontinuously, affecting the driving experience and safety. Inappropriate clutch state not only affects power efficiency, but also may increase the wear of the clutch and related transmission system components. By adjusting the clutch state in time according to the vehicle speed, unnecessary wear caused by state mismatch can be reduced and the life of the vehicle can be extended.

[0051] In some embodiments, controlling the clutch to switch from the slipping state to the disconnected state or the engaged state according to the vehicle speed includes:

[0052] In response to determining that the vehicle speed is greater than an upper limit vehicle speed of the target vehicle speed interval, switching the clutch from the slipping state to an engaged state;

[0053] In specific implementation, when it is determined that the vehicle speed exceeds the upper limit speed of the target speed range, it indicates that the vehicle speed is high. When driving at high speed, a fully engaged clutch can provide more stable and continuous power transmission, so the clutch is switched from the slipping state to the engaged state; the fully engaged clutch ensures that the engine power can be transmitted to the drive wheels without loss, providing the necessary power and acceleration capability.

[0054] In response to determining that the vehicle speed is less than a lower limit vehicle speed of the target vehicle speed interval, the clutch is switched from the slipping state to a disengaged state.

[0055] In specific implementation, when it is determined that the vehicle speed is less than the lower limit speed of the target speed range, it indicates that the vehicle speed is low. At a lower speed, completely disconnecting the clutch can completely stop the power output of the engine, allowing the vehicle to be driven by the electric motor, thereby adapting to the current driving speed and driving conditions. When driving at low speeds, by disconnecting the clutch and stopping the power output of the engine, fuel consumption and emissions can also be significantly reduced, especially in urban traffic congestion or frequent stop-start conditions. When driving at low speeds, the smooth and quiet driving experience provided by the electric motor is usually better than that of the engine, improving driving comfort.

[0056] In this embodiment, when the vehicle speed is higher than the upper limit of the target speed range, switching the clutch to the engaged state can ensure that the power of the engine is directly and losslessly transmitted to the drive wheels, which can provide continuous and stable power output, ensure the vehicle's acceleration performance and stability at high speeds, and optimize fuel efficiency. When the vehicle speed is lower than the lower limit of the target speed range, switching the clutch to the disengaged state can completely stop the power output of the engine, allowing the vehicle to be driven entirely by the electric motor, which usually provides a smoother and quieter driving experience than the engine. The ability to flexibly switch the clutch state according to the vehicle speed allows the vehicle to better adapt to different driving conditions and speed requirements.

[0057] In some embodiments, the operating data includes the power level of the vehicle power battery and the activation state of the vehicle electronic stability system; and determining that the operating data meets the sliding friction direct drive condition includes:

[0058] In response to determining that the power level of the vehicle power battery is less than or equal to a preset power level and the vehicle electronic stability system is in an inactive state, it is determined that the operating data meets a sliding direct drive condition.

[0059] In specific implementation, it is determined that the power of the vehicle power battery is less than or equal to the preset power (for example, the preset power can be set to 40%), indicating that the vehicle power is too low and the power battery cannot provide power for a long time; the electronic stability system is an important safety feature in modern vehicles for enhancing vehicle stability and preventing slippage. In the inactive state, it indicates that the current driving conditions allow some adjustments to the power transmission mode because the vehicle is in a relatively stable driving state. Therefore, when it is determined that the power of the vehicle power battery is less than or equal to the preset power, and the vehicle electronic stability system is in the inactive state, it is determined that the operating data meets the slip-and-grind direct drive condition, and the clutch of the vehicle can be controlled to switch from the current state to the slip-and-grind state. In the slip-and-grind state, the clutch allows partial torque transmission between the engine and the drive system. This partial torque transmission helps the vehicle to drive safely on slippery roads, and can reduce battery consumption, especially when the battery power is low, it can effectively utilize the power of the engine, extend the battery life and the driving distance of the vehicle.

[0060] In this embodiment, when the power battery is low, relying on pure electric mode to drive may cause the battery to be exhausted quickly, especially when a higher power output is required. Through the clutch slip state, the power of the engine can be reasonably utilized, thereby reducing the burden on the battery, extending the battery life and improving overall energy efficiency. When the electronic stability system is not activated, the introduction of the slip state can allow torque transfer between the engine and the motor while ensuring vehicle stability, providing a smoother acceleration and deceleration experience, and reducing vehicle shaking or sliding caused by inconsistent power output.

[0061] In some embodiments, after controlling the clutch of the vehicle to switch from the current state to the slip state, the method further includes:

[0062] determining the intervention torque sent by the transmission control unit as the engine fast-path torque;

[0063] In specific implementation, the transmission control unit is responsible for monitoring and adjusting the behavior of the transmission to ensure that the engine speed matches the vehicle speed. The engine fast-path torque refers to the torque output of the engine at high speeds. The engine fast-path torque can be adjusted quickly in response to the transmission control unit signal. After the vehicle's clutch switches to the slip state, the clutch plate and the flywheel are not fully engaged, but partially in contact, so that the engine speed cannot be completely and directly converted into the rotation of the drive wheel, resulting in incoherent engine torque transmission, which causes speed fluctuations. The transmission control unit adjusts the engine output by sending intervention torque, which helps to maintain the stability of the engine speed during the speed change process. In speed changes or other situations where torque needs to be adjusted quickly, the fast-path torque can be adjusted quickly to help stabilize the engine speed. The engine's fast-path torque is determined by the intervention torque sent by the transmission control unit, with the aim of stabilizing the engine speed under various driving conditions, thereby optimizing the overall performance and efficiency of the vehicle.

[0064] A gas circuit torque request value is determined, and the gas circuit torque request value is compared with an engine maximum torque limit value sent by a transmission control unit to determine a minimum value between the gas circuit torque request value and the engine maximum torque limit value as the engine slow circuit torque.

[0065] In specific implementation, the gas circuit torque request value is usually calculated based on the driver's accelerator pedal input, the current speed of the vehicle, and other operating conditions. The gas circuit torque request value indicates how much torque the engine needs to provide to meet the current driving demand. The transmission control unit sends an engine maximum torque limit value based on the engine's capabilities, the state of the transmission, and possible environmental and mechanical limitations. The maximum torque limit value is the maximum torque that the engine can safely provide without damaging the transmission and other vehicle components. Slow-road torque refers to the torque generated by the engine at low speeds. At low speeds, the engine's torque output is higher, and the slow-road torque cannot be adjusted quickly to respond to the transmission control unit signal. It is usually used for smoother torque changes and is suitable for non-emergency normal driving conditions. The gas circuit torque request value is compared with the engine maximum torque limit value sent by the transmission control unit, and the minimum of the two is taken as the engine's slow-road torque. Ensure that the engine does not output torque exceeding the mechanical safety regulations and stabilize the engine speed as much as possible. By accurately controlling the engine torque output, it is possible to ensure vehicle performance while avoiding excessive load on the engine and transmission.

[0066] In this embodiment, the engine fast-path torque allows the torque output to be quickly adjusted to adapt to changes in speed changes or other driving conditions, thereby improving the responsiveness of the vehicle. By precisely controlling the torque output, the engine can operate in a more economical and environmentally friendly state. Slow-path torque helps the engine maintain its optimal operating range through smooth torque changes, thereby improving fuel efficiency and reducing emissions. By comparing the gas path torque request value with the engine maximum torque limit value, it ensures that the engine does not output more torque than the transmission and other vehicle components can safely handle. It helps to reduce mechanical wear and potential failures caused by excessive torque and extend the service life of the transmission system. Precise torque control can provide a smoother driving experience, especially during speed changes, avoiding engine speed jitter caused by sudden changes in torque.

[0067] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
