Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to a vehicle control method and a vehicle. Background Technology

[0002] Currently, with increasingly stringent national regulations on vehicle fuel consumption and emission standards, and the continuous development of electrification systems, achieving energy conservation and emission reduction has become an important goal and development direction for the automotive industry. Against this backdrop, hybrid vehicles, with their significant advantages in energy conservation and emission reduction, are considered key to achieving this goal.

[0003] In hybrid systems, start-stop, hybrid drive, and pure electric drive functions play a crucial role in the normal operation of the vehicle. However, improper handling of the various state switching operations, such as enabling and disabling, of key components like the engine and motor in a hybrid system can lead to vehicle safety and reliability issues. Therefore, determining the state of the hybrid system and controlling the vehicle to improve its safety and reliability has become an urgent technical problem to be solved. Summary of the Invention

Detailed Implementation

[0015] 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.

[0016] 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.

[0017] It should be understood that the steps described in the method embodiments of this disclosure may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. 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. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0019] 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".

[0020] In hybrid systems, functions such as start-stop, hybrid drive, and pure electric drive typically play a crucial role in the normal operation of the vehicle. For example... Figure 2 As shown, the hybrid power system has three modes: pure electric mode, series mode, and parallel mode. In pure electric mode, the P2 motor drives the wheels; in series mode, the C0 clutch is not engaged, the engine charges the battery through the P1 motor, and the P2 motor drives the wheels; in parallel mode, the C0 clutch is engaged, and the engine directly drives the wheels. However, improper handling of the various state switching operations, such as enabling and disabling, of key components in the hybrid power system, including the engine and motor, can lead to vehicle safety and reliability issues. Therefore, determining the state of the hybrid power system to control the vehicle and improve its safety and reliability has become an urgent technical problem to be solved. To address this problem, this disclosure provides a vehicle control method, which will be described below with reference to specific embodiments.

[0021] Figure 1 This is a flowchart of a vehicle control method provided in an embodiment of the present disclosure. The method can be executed by a vehicle control device, which can be implemented in software and / or hardware. The vehicle control device can be configured in an electronic device, such as a server or terminal, wherein the terminal specifically includes a mobile phone, computer or tablet computer, etc.

[0022] like Figure 1 As shown, the vehicle control method provided in this disclosure can be applied to hybrid vehicles. The vehicle control method may include the following steps.

[0023] S110. When the vehicle is detected to be powered on, obtain the vehicle's current operating status information.

[0024] In this embodiment of the disclosure, the vehicle being in a powered-on state can be understood as the vehicle having entered an operable power-on preparation phase, that is, the state machine of the vehicle's hybrid power system has been activated, and it begins to monitor and judge all enabling conditions in real time, preparing for the intelligent switching and response of the power mode. The state machine can be understood as a set of rule logic for switching the power state of the vehicle's hybrid power system.

[0025] In this embodiment of the disclosure, the current operating condition information of the vehicle may include hybrid system request information, engine speed, number of cylinders with fuel cut-off, engine start permission signal, anti-lock braking system status information, gear information, vehicle speed, actual driving direction of the vehicle, clutch status information, vehicle fault information, motor control mode, driving cycle status information, door status information, seat belt status information, etc., without limitation.

[0026] In some embodiments of this disclosure, the electronic device can detect the position of the vehicle's key switch in real time. When the position of the vehicle's key switch is detected to be greater than or equal to 2, it determines that the vehicle is in a powered-on state, and then obtains the vehicle's current operating status information in real time through the vehicle's sensors and the vehicle's bus network.

[0027] In other embodiments of this disclosure, the electronic device can detect the ignition switch position signal or the trigger state of the smart start button in real time. When it detects that the ignition switch position signal is in the open state, or when it detects that the smart start button is triggered, it determines that the vehicle is powered on, and then obtains the vehicle's current operating status information in real time through the vehicle's sensors and the vehicle's bus network.

[0028] It should be noted that the method for monitoring whether a vehicle is powered on varies depending on the actual application scenario and the vehicle model. The specific method should be determined based on the actual situation and is not limited here.

[0029] S120. Based on the vehicle's current operating condition information, determine the vehicle's engine status, motor status, and vehicle power-off status respectively.

[0030] In this embodiment of the disclosure, the engine state may include a stopped state, a running state, a stopped state, a starting state, and an abnormal stopped state.

[0031] Motor status can be understood as the enabled and disabled states of each motor, specifically including the status of the rear axle drive motor, the status of the front axle drive motor, and the status of the target motor.

[0032] The vehicle's power-off state can include being in an enabled state or being in an activated state.

[0033] Specifically, after acquiring the vehicle's current operating condition information, the electronic device further determines the vehicle's engine status, motor status, and vehicle power-off status based on the vehicle's current operating condition information and preset engine status judgment conditions, motor status judgment conditions, and vehicle power-off status judgment conditions.

[0034] S130: The power state of the vehicle's hybrid system is switched based on the engine state, motor state, and vehicle power-off state.

[0035] In this embodiment of the disclosure, the power state of the hybrid system may include a wake-up state, a vehicle power-on state, a start-up request state, a start-up state, an engine start state, a pure electric drive state, a power-off state, a driving start state, and a remote start state.

[0036] Specifically, after acquiring the vehicle's engine status, motor status, and vehicle power-off status, the electronic equipment determines the target power status of the matching hybrid power system based on these statuses. It then sends the target power status signal to the bus network to switch the power status of the hybrid power system, ensuring the accuracy and rationality of the power status switching.

[0037] In this embodiment, when the vehicle is detected to be powered on, the current operating condition information of the vehicle can be obtained. After obtaining the current operating condition information, the engine state, motor state, and vehicle power-off state of the vehicle are determined based on the current operating condition information. Then, the power state of the hybrid power system is switched based on the engine state, motor state, and vehicle power-off state. Therefore, the state of each power source of the vehicle (i.e., engine state and motor state) can be determined according to the real-time operating condition information of the vehicle. Based on the state of each power source and the vehicle power-off state, the power state switching of the hybrid power system is performed. This takes into account the enabling and disabling of each power source under different operating conditions and the vehicle power-off state when performing the power state switching of the hybrid power system, improving the accuracy and rationality of the power state switching of the hybrid power system, thereby improving the safety and reliability of the vehicle.

[0038] In some embodiments of this disclosure, the vehicle's current operating condition information may include hybrid power system request information, engine speed, and number of cylinders with fuel cut-off.

[0039] Electronic devices can determine the vehicle's engine status based on the hybrid system request information, engine speed, and number of cylinders with fuel cut-off from the current operating condition information. The following will combine... Figure 3 A detailed introduction will be provided.

[0040] Figure 3 This is a flowchart of an engine state determination method provided in an embodiment of this disclosure, such as... Figure 3 As shown, based on the vehicle's current operating condition information, the engine status of the vehicle is determined, which may specifically include the following steps: S310. Determine whether the hybrid power system request information includes an engine start request.

[0041] In this embodiment of the disclosure, the engine start request is a request to start the engine.

[0042] In this embodiment of the disclosure, step S320 is executed when there is no engine start request; when there is an engine start request, the engine state is determined based on the number of cylinders cut off and the engine speed, and steps S330 to S360 are executed.

[0043] S320. If the hybrid power system request information does not include an engine start request, determine that the engine status is that the engine is in a stopped state.

[0044] S330. When the hybrid system request information includes an engine start request, calculate the ratio of the number of cylinders with fuel cut-off to the total number of cylinders in the vehicle, determine the ratio as the current fuel cut-off coefficient of the vehicle, and compare the engine speed with the first speed threshold and the second speed threshold respectively.

[0045] In this embodiment of the disclosure, the first speed threshold is greater than the second speed threshold. The first speed threshold includes the speed threshold corresponding to engine startup and the speed threshold during normal engine operation.

[0046] The second speed threshold is the speed threshold used to characterize the engine stoppage.

[0047] S340. If the duration of the engine speed being greater than the first speed threshold is greater than the first preset duration threshold, and the current fuel cut-off coefficient is lower than the preset coefficient threshold, the engine state is determined to be in the running state.

[0048] S350: If the duration of the engine speed being less than the second speed threshold is greater than the second preset duration threshold, the engine state is determined to be that the engine is in a stopped state.

[0049] S360: When the engine speed is less than or equal to the first speed threshold and the current fuel cut-off coefficient is higher than or equal to the preset coefficient threshold, the engine status is determined to be that the engine is in a shutdown state.

[0050] In this embodiment, the system's control intent can be determined by the engine start request, and the engine speed directly reflects the actual movement of the crankshaft. At the same time, the current fuel cut-off coefficient is determined by the number of fuel-cut cylinders, which reveals the internal combustion and control state of the engine in depth. It can effectively identify special operating conditions such as "stalling" and "limp-out". This not only avoids the problem of misjudgment of a single signal, but also accurately captures the complete transient process from start-up, operation to shutdown, providing a reliable state foundation for the mode switching of the hybrid power system, thereby significantly improving the system's control accuracy, response speed and overall robustness.

[0051] In other embodiments of this disclosure, the vehicle's current operating condition information includes hybrid system request information, engine start permission signal, and anti-lock braking system status information. Electronic devices can further determine the engine's status based on the hybrid system request information, engine start permission signal, and anti-lock braking system status information to determine if an abnormal shutdown has occurred. The following will combine... Figure 4 A detailed introduction will be provided.

[0052] Figure 4 This is a flowchart of another engine state determination method provided in this disclosure embodiment, such as... Figure 4 As shown, based on the vehicle's current operating condition information, the engine status of the vehicle is determined, which may specifically include the following steps: S410. Determine whether the hybrid power system request information includes an engine start request and a rapid stop request.

[0053] In this embodiment of the disclosure, a rapid shutdown request can be understood as a request for the engine to stop running immediately. This can achieve purposes such as handling emergency situations, ensuring safety, and preventing component damage.

[0054] S420. If the hybrid power system request information includes an engine start request but does not include a rapid stop request, determine whether the engine start permission signal allows the electric motor or starter to start the engine and whether the anti-lock braking system status is that the anti-lock braking system is in an active state.

[0055] In this embodiment of the disclosure, allowing the motor to start the engine can be understood as allowing the target motor to... Figure 2 The P1 motor in the diagram starts the engine. Allowing the starter motor to start the engine can be understood as allowing the engine to be started using a 12V starting method.

[0056] In this embodiment of the disclosure, the electronic device can determine whether the anti-lock braking system is active based on the activation flag of the anti-lock braking system.

[0057] S430. When the engine start permission signal allows the motor or starter to start the engine, and the anti-lock braking system is in the active state, the engine state is determined to be the engine starting state.

[0058] S440. If the hybrid power system request information includes a rapid shutdown request, determine that the engine is in an abnormal shutdown state.

[0059] In this embodiment of the disclosure, the abnormal shutdown state is the stall state.

[0060] In this embodiment of the disclosure, when the electronic device determines that the hybrid power system request information includes a rapid shutdown request, it further determines whether the conditions for entering an abnormal shutdown state are met. If it is determined that any one or more of the conditions for entering an abnormal shutdown state are met, the engine is determined to be in an abnormal shutdown state, and the abnormal shutdown state flag is set.

[0061] In this embodiment of the disclosure, before determining whether the hybrid power system request information contains a rapid shutdown request, the vehicle control method may further include: determining whether to trigger a rapid shutdown request based on one or more of the engine operating status information, engine speed changes, and hybrid power system request information.

[0062] The engine's operating status information includes information characterizing the engine's current operating status and / or start-up status. For example, the engine's operating status information may include whether the engine is running, the engine start-up time, and whether the engine has started successfully.

[0063] The hybrid power system request information includes information indicating that the engine, electric motor, and starter motor are requesting to start. For example, the hybrid power system request information may include an engine start-prevention request, an engine shutdown request, an electric motor start-prevention signal, and a starter motor start-prevention signal.

[0064] Specifically, a fast shutdown request is triggered if one or more of the following examples are met.

[0065] In some examples, it is determined whether the engine is running and whether the engine speed drops below a target speed threshold within a preset time period; if the engine is running and the engine speed drops below the target speed threshold within a preset time period, a rapid shutdown request is triggered.

[0066] In other examples, it is determined whether the engine start time exceeds a preset time threshold; if the engine start time exceeds the preset time threshold, a rapid shutdown request is triggered.

[0067] In some other examples, it is determined whether the hybrid power system request information contains an engine start-prevention request or an engine shutdown request; if the hybrid power system request information contains an engine start-prevention request or an engine shutdown request, it is determined to trigger a rapid shutdown request.

[0068] In some other examples, it is determined whether the operating condition information contains a motor start-prohibition signal or a starter start-prohibition signal; if the operating condition information contains a motor start-prohibition signal or a starter start-prohibition signal, a rapid shutdown request is triggered.

[0069] Furthermore, in the event of an abnormal engine shutdown, the electronic equipment further determines whether to enter a vehicle power-down state, meaning that automatic engine restart is no longer allowed and the engine can only be started manually by the driver.

[0070] In this embodiment of the disclosure, the conditions for determining whether the engine should remain in an abnormal stop state until the driver manually starts the engine after the engine enters an abnormal stop state are as follows: the number of times the engine enters an abnormal stop state during automatic start-up is greater than a preset number threshold, the duration of entering an abnormal stop state is greater than a target preset duration threshold, the vehicle speed is greater than a preset vehicle speed threshold, the driver's corresponding seat belt status is unfastened, the start-stop function is in the off state, and the coolant temperature is lower than a preset temperature threshold.

[0071] In this embodiment of the disclosure, the abnormal shutdown state recovery conditions include the engine speed being zero, i.e., the engine completely stopping, the transmission disengaging, or the accelerator pedal opening being greater than a preset pedal opening threshold, and the vehicle not entering an abnormal shutdown and power-off state; or, the abnormal shutdown state recovery condition is in response to the driver's key turning operation.

[0072] In this embodiment of the disclosure, when an engine start request is triggered, a transmission engagement request should also be triggered simultaneously; that is, a transmission engagement request or a transmission disengagement request is generated in conjunction with the engine start request. If the hybrid system request information does not include a rapid shutdown request, and engine shutdown is required, the following conditions must be met: vehicle speed is less than a preset vehicle speed threshold, the drivetrain is disengaged, the requested crankshaft torque is less than a preset crankshaft torque threshold, the engine speed is less than a preset speed threshold, or the engine shutdown request has been in effect for a preset duration. Only then is an engine shutdown request triggered.

[0073] In this embodiment of the disclosure, when there is an engine running request and other modules request the transmission to engage, and the current vehicle speed is greater than a first vehicle speed threshold or the engine is already running, the transmission can be requested to engage; when there is no transmission engagement request but there is an engine running request, the transmission can be requested to enter neutral mode; when the vehicle speed is lower than a second vehicle speed threshold (i.e., indicating that the vehicle has stopped), the transmission can also be requested to enter neutral mode.

[0074] The required torque can only be allocated to the engine after the transmission power transmission path is enabled. For example, in pure electric mode, the crankshaft power transmission path will always be disabled. The crankshaft power transmission path can only be enabled if the following conditions are met: there is an engine operation request and a request for transmission engagement (i.e., the vehicle is in drive (D) or reverse (R) gear), or there is an engine operation request, but the gear is in park (P) or neutral (N) gear; power propulsion is permitted; the engine is running; the transmission is engaged or responding to engagement, or the gear is in park (P) or neutral (N) gear, or neutral (N) gear is disabled.

[0075] In this embodiment of the disclosure, after determining the engine state, the flag corresponding to the engine state is set to a bit position.

[0076] In this embodiment, by comprehensively analyzing the control intent (start / stop request), enabling conditions (start permission), and vehicle safety status (ABS status), the system can deeply bind the engine's physical state (such as speed) with the upper-level control logic and the vehicle safety boundary. This not only ensures a high degree of consistency between the state judgment and the system command, avoiding logical conflicts that may be caused by relying solely on physical sensors, but more importantly, it directly embeds safety logic (such as rapid shutdown to deal with risks) into the core conditions of state machine transitions, thereby achieving seamless connection from power control to safety response, significantly improving the reliability, robustness, and overall vehicle safety level of the system decision-making.

[0077] In this embodiment, the motor status may include the rear axle drive motor status, the front axle drive motor status, and the target motor status. The vehicle's current operating condition information includes hybrid system request information, gear information, vehicle speed, actual vehicle direction, and clutch status information.

[0078] In this embodiment of the disclosure, the motor status of the vehicle is determined based on the current operating condition information of the vehicle. Specifically, this may include: determining whether the motor is in an active state based on whether the hybrid power system request information contains one or more of the following: information used to characterize the operation of the motor, gear information, and motor fault information; if the motor is determined to be in an active state, the motor status is determined based on whether the hybrid power system request information contains a clutch engagement request, gear information, and clutch status information.

[0079] The motor status includes enabled state, disabled state, and standby state.

[0080] The motor may include a rear axle drive motor, a front axle drive motor, and a target motor for starting the engine and generating electricity.

[0081] The following will combine Figure 5The specific implementation method for determining the state of the rear axle drive motor is described in detail.

[0082] Figure 5 This is a flowchart of a method for determining the state of a rear axle drive motor according to an embodiment of this disclosure, such as... Figure 5 As shown, based on the vehicle's current operating condition information, the motor status of the vehicle is determined, which may specifically include the following steps: S510. Determine whether the hybrid power system request information includes an engine operation request or an electric motor activation request.

[0083] In this embodiment of the disclosure, the motor activation request can be understood as a request from other modules in the vehicle to activate the rear axle drive motor. For example, when a large torque is needed, the rear axle drive motor is requested to drive the rear axle drive motor; when the torque requirement at idle is very small, the rear axle drive motor is requested to provide torque; and in four-wheel drive mode, the rear axle drive motor is needed to drive the rear axle.

[0084] S520. If the hybrid system request information does not include an engine operation request or includes an electric motor activation request, determine whether the target driving direction corresponding to the gear information is consistent with the actual driving direction of the vehicle, and whether the vehicle speed is less than the target vehicle speed threshold.

[0085] In this embodiment of the disclosure, the target vehicle speed threshold is the maximum vehicle speed allowed by the rear axle drive motor.

[0086] Among them, whether the target driving direction corresponding to the gear information is consistent with the actual driving direction of the vehicle can be understood as whether the vehicle is moving in the expected direction, such as whether the vehicle moves forward when in forward gear and whether the vehicle moves backward when in reverse gear.

[0087] S530. When the target driving direction is consistent with the actual driving direction of the vehicle and the vehicle speed is less than the target vehicle speed threshold, it is determined that the rear axle drive motor of the vehicle is in an active state.

[0088] S540. When the rear axle drive motor of the vehicle is in an active state, determine whether the hybrid system request information includes a rear axle drive motor clutch engagement request, and whether the clutch status corresponding to the rear axle drive motor in the clutch status information is in an engaged state.

[0089] In this embodiment of the disclosure, when the rear axle drive motor of the vehicle is in an active state, and the hybrid system is allowed to propel the vehicle while the diagnostic module allows the rear axle drive motor to output torque, a rear axle drive motor clutch engagement request can be generated.

[0090] S550: If the hybrid power system request information includes a request for engagement of the rear axle drive motor clutch, and the clutch status corresponding to the rear axle drive motor is engaged, then the rear axle drive motor is determined to be in an enabled state.

[0091] In this embodiment of the disclosure, if the hybrid power system request information includes a rear axle drive motor clutch engagement request and the clutch state corresponding to the rear axle drive motor is in an engaged state, the rear axle drive motor enters a torque control mode, thereby determining that the rear axle drive motor is in an enabled state.

[0092] S560. If the hybrid system request information does not include a request for engagement of the rear axle drive motor clutch, and the clutch status corresponding to the rear axle drive motor is in a disengaged state, it is determined that the rear axle drive motor is in an inactive state.

[0093] In this embodiment of the disclosure, if the hybrid power system request information does not include a request for engagement of the rear axle drive motor clutch and the clutch state corresponding to the rear axle drive motor is in a disengaged state, the rear axle drive motor enters a speed control mode, thereby determining that the rear axle drive motor is in a disabled state.

[0094] S570. If the hybrid system request information does not include a request for engagement of the rear axle drive motor clutch, and the clutch status corresponding to the rear axle drive motor is engaged, then the rear axle drive motor is determined to be in standby mode.

[0095] In this embodiment of the disclosure, after determining the state of the rear axle drive motor, the flag corresponding to the state of the rear axle drive motor is set to a new position.

[0096] In this embodiment, by judging power requests (engine / other module requests), it is ensured that the motor is only activated when the system truly needs additional torque or a specific driving mode, avoiding unnecessary energy consumption. By verifying the consistency between the gear position and the actual driving direction, the risk of reverse drive caused by signal errors or misoperation is fundamentally eliminated, ensuring mechanical safety and accurate execution of driving intentions. The introduction of a vehicle speed threshold limits the inefficient operation of the motor in the high-speed range, protecting both the motor and transmission components while optimizing the system's energy distribution. This multi-condition coupled judgment strategy maximizes the unity of safety protection and energy efficiency management while meeting power requirements, thereby further improving the accuracy of power state switching in the hybrid system.

[0097] The following will combine Figure 6 A detailed explanation of the status judgment of the front axle drive motor is provided.

[0098] Figure 6 This is a flowchart of a method for determining the state of a front axle drive motor provided in an embodiment of this disclosure, as follows: Figure 6 As shown, based on the vehicle's current operating condition information, the motor status of the vehicle is determined, which may specifically include the following steps: S610, determine whether the hybrid system request information includes a front axle drive motor torque request, and determine whether the front axle drive motor is in a fault state based on vehicle fault information.

[0099] S620: If the hybrid system request information includes a front axle drive motor torque request and the front axle drive motor is not in a fault state, determine that the front axle drive motor is in an active state.

[0100] S630: When the front axle drive motor is active, determine whether the vehicle is in first gear based on the gear information.

[0101] In this embodiment of the disclosure, the first gear may include forward gear (D) and reverse gear (R).

[0102] S640. When the vehicle is in first gear, ensure that the front axle drive motor is enabled.

[0103] In this embodiment of the disclosure, after determining that the front axle drive motor is in an enabled state, the enable flag corresponding to the front axle drive motor is set to a specific position.

[0104] The following will combine Figure 7 The specific methods for determining the state of the target motor are described in detail.

[0105] Figure 7 This is a flowchart of a method for determining the state of a target motor provided in an embodiment of this disclosure, as follows: Figure 7 As shown, based on the vehicle's current operating condition information, the motor status of the vehicle is determined, which may specifically include the following steps: S710 determines whether the hybrid system request information includes a target motor torque request, and determines whether the target motor is in a fault state based on vehicle fault information.

[0106] In this embodiment of the disclosure, the target motor is a motor used for starting the engine and generating electricity. For example... Figure 2 The P1 motor is shown.

[0107] S720: If the hybrid power system request information includes a target motor torque request and the target motor is not in a fault state, determine that the target motor is in an active state.

[0108] S730: When the target motor is in an active state, determine whether the target motor is in torque control mode based on the motor control mode.

[0109] S740. When the target motor is in torque control mode, determine that the target motor is in an enabled state.

[0110] In this embodiment, detecting torque requests ensures that the motor is only activated when the system actually needs to drive or generate electricity, achieving energy efficiency optimization through on-demand operation. By incorporating fault diagnosis information in real time, the motor can be immediately disabled or isolated when an abnormality occurs, fundamentally preventing fault propagation and secondary damage, and ensuring the safety of the core powertrain. Simultaneously, combined with the verification of the D / R gear signal, it ensures that the motor's operating logic strictly conforms to the vehicle's driving intention, avoiding malfunctions in non-driving states such as P / N gears. This multi-dimensional coupled judgment mechanism accurately responds to power demands while maximizing the balance between system safety, functional integrity, and energy efficiency.

[0111] In this embodiment, the vehicle's current operating condition information includes hybrid system request information, driving cycle status information, door status information, seat belt status information, gear information, vehicle speed, and engine speed. Electronic devices can determine the vehicle's power-down state based on this current operating condition information. The following will combine... Figure 8 The specific methods for determining the power-off status of the entire vehicle are described in detail.

[0112] Figure 8 This is a flowchart of a method for determining the power-off state of a vehicle according to an embodiment of this disclosure, as follows: Figure 8 As shown, based on the vehicle's current operating condition information, determining the vehicle's power-off state can specifically include the following steps: S810, determine whether the hybrid system request information includes an engine start request, determine whether the vehicle's driving cycle state is active based on the driving cycle state information, whether the vehicle speed is less than the target preset vehicle speed threshold, and whether the engine speed is less than the third speed threshold.

[0113] In this embodiment of the disclosure, the third speed threshold may be a speed threshold used to characterize that the vehicle engine is in a stopped state.

[0114] S820. If the hybrid system request information does not include an engine start request, the vehicle's driving cycle is active, the vehicle speed is less than the target preset speed threshold, and the engine speed is less than the third speed threshold, then the vehicle is determined to be in a vehicle power-off enabled state.

[0115] In this embodiment of the disclosure, the driving cycle state of the vehicle being in an active state can be understood as allowing the powertrain to output power, and there is an engine start request, while the starter, engine, motor and other states are all ready; after the engine has started, the flag is also set, at which point it is determined that the driving cycle state is in an active state.

[0116] S830. When the vehicle is in a vehicle power-off enabled state, determine whether the vehicle meets the preset power-off trigger conditions.

[0117] In this embodiment of the disclosure, the preset power-down trigger conditions include at least one of the following: the door status information is that the door corresponding to the driver is in an open state, the gear information is that the gear is in the second gear, and the seat belt status information is that the seat belt is unfastened (i.e., the driver has left); the duration of the gear information being in the second gear and the seat belt being unfastened is greater than a third preset duration threshold (i.e., the driver has left); the start-stop function is in a disabled state; the engine starting is in a disabled state; and the transmission control system is in a fault state.

[0118] S840. If the vehicle meets any one or more of the preset trigger conditions, determine that the vehicle is in the vehicle power-off activation state.

[0119] In this embodiment, by verifying the driving cycle, vehicle speed, and engine speed, it is ensured that the power-down process is only allowed to start when the vehicle is safely stationary and the power source is in a steady state, laying a physical foundation for safe power-down. Furthermore, using events such as driver departure, disabling of critical functions, or system malfunction as direct triggers for power-down enables the mechanism to respond instantly to various safety risks and abnormal operating conditions. This ensures that when personnel leave the site, the system fails, or potential dangers exist, the vehicle can proactively and reliably enter a safe power-down state that cannot be accidentally driven. This design, with its "strict control over enabling conditions and broad coverage of triggering conditions," maximizes the safety of personnel and the vehicle while avoiding accidental power-down during normal use, achieving an optimal balance between safety and availability.

[0120] In some embodiments of this disclosure, switching the power state of the vehicle's hybrid system based on engine state, motor state, and vehicle power-off state may specifically include: determining whether the motor state is enabled and whether the vehicle power-off state is active; if the vehicle power-off state is inactive and the motor state is disabled, switching the power state of the vehicle's hybrid system based on the engine state; if the vehicle power-off state is inactive and the engine state is stopped, switching the power state of the vehicle's hybrid system based on the engine stop type and motor state; if the vehicle power-off state is active, switching the power state of the vehicle's hybrid system to the power-off state.

[0121] Specifically, when it is determined that the vehicle is in an inactive state when it is powered down and the motor is in an enabled state, the power state of the vehicle's hybrid system is switched based on the engine state. This can specifically include: when the engine is in a stopped state, switching the power state of the vehicle's hybrid system to a powered-on state; when the engine is in a starting state, switching the power state of the vehicle's hybrid system to a starting state; and when the engine is in a running state, switching the power state of the vehicle's hybrid system to an engine-starting state.

[0122] When it is determined that the vehicle is in an inactive state and the engine is in a stopped state, the power state of the vehicle's hybrid system is switched based on the engine stop type and the motor state. Specifically, this may include: when the engine stop type is "already stopped" and the motor state is "motor enabled", switching the power state of the vehicle's hybrid system to pure electric drive state; when the engine stop type is "abnormal stop" and the motor state is "at least one motor enabled", switching the power state of the vehicle's hybrid system to "awakened state".

[0123] When it is determined that the vehicle's power-off state is active, the power state of the vehicle's hybrid system is switched to the power-off state. Specifically, this may include: when the engine is in an abnormal shutdown state and the motor is in an inactive state, switching the power state of the vehicle's hybrid system to the power-off state; when the engine is running and at least one motor is in an enabled state, performing motor de-enabling and engine shutdown operations, and after the engine stops and both motors are in an inactive state, switching the power state of the vehicle's hybrid system to the power-off state.

[0124] In this embodiment, by coupling the operating states of the engine and motor in real time, it is ensured that the current power demand and source capacity can be accurately matched, and seamless switching between pure electric, series, and parallel modes can be achieved to maximize energy efficiency and ensure power smoothness. At the same time, combined with the vehicle's power-off state, the system not only manages the energy distribution during driving, but also actively plans the shutdown process. This not only improves the economy and responsiveness of daily driving, but also extends the life of components and ensures the system's safety and reliability under all operating conditions.

[0125] In other embodiments of this disclosure, before switching the power state of the vehicle's hybrid system based on engine state, motor state, and vehicle power-off state, the start-stop function state of the vehicle is determined based on the vehicle's current operating condition information; the power state of the vehicle's hybrid system is switched based on the vehicle's start-stop function state, engine state, motor state, and vehicle power-off state.

[0126] In this embodiment, determining the vehicle's start-stop function status based on the vehicle's current operating condition information may specifically include: determining whether the anti-lock braking system (ABS) is active, whether the braking system allows start-stop, whether the gear signal corresponding to the gear position information is normal, whether the vehicle's driving mode is in economy mode, whether the driver's door is closed and the seatbelt is fastened, whether the transmission control system is faulty, whether the hybrid system request information includes a request to prohibit start-stop, whether the hood is closed, and whether the vehicle's driving mode allows start-stop. If the ABS is active, the braking system allows start-stop, the gear signal is normal, the driving mode is economy, the driver's door is closed and the seatbelt is fastened, the transmission control system is normal, the hybrid system request information does not include a request to prohibit start-stop, the hood is closed, and the driving mode allows start-stop, then the vehicle's start-stop function is enabled. Otherwise, the vehicle's start-stop function is disabled.

[0127] Furthermore, when the vehicle's engine is in the starting state and the vehicle's start-stop function is enabled, the electronic equipment determines the power state of the hybrid system as the driving start state.

[0128] In this embodiment, the system can intelligently determine whether the engine should be shut down at idle to save fuel based on the vehicle's start-stop function status. By comprehensively considering the real-time operating status of the engine and motor, the system can precisely allocate or switch power sources, ensuring smooth and efficient power output. Furthermore, by incorporating the vehicle's power-off status, the system can proactively manage the shutdown process and optimize energy storage as the vehicle is about to shut down, preparing for the next start-up. This collaborative control strategy, based on the top-level system status, ensures that power mode switching is not only timely and smooth but also achieves overall system optimization in terms of energy consumption, safety, and durability.

[0129] In this embodiment of the disclosure, the electronic device can also determine that the power state of the vehicle's hybrid system is in a remote start state when the vehicle receives a remote start request. This allows for adaptation to different vehicle start methods and improves the flexibility of switching the power state of the vehicle's hybrid system.

[0130] In this embodiment of the disclosure, when the position of the vehicle's key switch is less than 2 and there is no wake-up request, it is determined that the power state of the vehicle's hybrid system is in the power-off state, i.e., the normal engine-off state; when the hybrid system request information includes a wake-up request, it is determined that the power state of the vehicle's hybrid system is in the wake-up state.

[0131] Figure 9 This is a schematic diagram of the structure of a vehicle control device provided in an embodiment of this disclosure.

[0132] In this embodiment, the vehicle 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 mobile phones, computers, or tablet computers, etc., without limitation.

[0133] like Figure 9 As shown, the vehicle control device 900 may include an information acquisition module 910, a status determination module 920, and a vehicle control module 930.

[0134] The information acquisition module 910 can be used to acquire the current operating status information of the vehicle when the vehicle is detected to be powered on. The status determination module 920 can be used to determine the vehicle's engine status, motor status, and vehicle power-off status based on the vehicle's current operating condition information. The vehicle control module 930 can be used to switch the power state of the vehicle's hybrid system based on engine status, motor status, and vehicle power-off status.

[0135] In this embodiment, when the vehicle is detected to be powered on, the current operating condition information of the vehicle can be obtained. After obtaining the current operating condition information, the engine state, motor state, and vehicle power-off state of the vehicle are determined based on the current operating condition information. Then, the power state of the hybrid power system is switched based on the engine state, motor state, and vehicle power-off state. Therefore, the state of each power source of the vehicle (i.e., engine state and motor state) can be determined according to the real-time operating condition information of the vehicle. Based on the state of each power source and the vehicle power-off state, the power state switching of the hybrid power system is performed. This takes into account the enabling and disabling of each power source under different operating conditions and the vehicle power-off state when performing the power state switching of the hybrid power system, improving the accuracy and rationality of the power state switching of the hybrid power system, thereby improving the safety and reliability of the vehicle.

[0136] In some embodiments of this disclosure, the vehicle's current operating condition information includes hybrid power system request information, engine speed, and number of cylinders with fuel cut-off.

[0137] The status determination module 920 can be specifically used to determine the engine status as the engine is in a stopped state when the hybrid power system request information does not contain an engine start request. If the hybrid system request information includes an engine start request, the engine status is determined based on the number of cylinders cut off and the engine speed.

[0138] In some embodiments of this disclosure, the state determination module 920 may also be specifically used to determine the current fuel cut-off coefficient of the vehicle based on the number of fuel cut-off cylinders; If the duration of the engine speed being greater than the first speed threshold is greater than the first preset duration threshold, and the current fuel cut-off coefficient is lower than the preset coefficient threshold, the engine status is determined to be that the engine is in operation. If the duration of the engine speed being less than the second speed threshold is greater than the second preset duration threshold, the engine state is determined to be that the engine is in a stopped state, and the first speed threshold is greater than the second speed threshold. If the engine speed is less than or equal to the first speed threshold and the current fuel cut-off coefficient is higher than or equal to the preset coefficient threshold, the engine status is determined to be that the engine is in a shutdown state.

[0139] In some embodiments of this disclosure, the vehicle's current operating condition information includes hybrid power system request information, engine start permission signal, and anti-lock braking system status information.

[0140] The status determination module 920 can also be used to determine whether the engine start permission signal allows the motor or starter to start the engine and whether the anti-lock braking system status is active when the hybrid power system request information includes an engine start request but does not include a rapid stop request. If the engine start permission signal allows the motor or starter to start the engine, and the anti-lock braking system is in the active state, then the engine state is determined to be the engine starting state. If the hybrid power system request message includes a rapid shutdown request, it is determined that the engine is in an abnormal shutdown state.

[0141] In some embodiments of this disclosure, the vehicle control device 900 may further include a rapid stop request triggering judgment module.

[0142] The rapid shutdown request triggering judgment module can be used to determine whether to trigger a rapid shutdown request based on one or more of the engine's operating status information, engine speed changes, and the hybrid system request information before determining whether the hybrid system request information contains a rapid shutdown request. The engine's operating status information includes information that characterizes the engine's current operating status and / or start-up status; the hybrid system request information includes information that characterizes the engine, motor, and starter motor's request to start.

[0143] In some embodiments of this disclosure, the vehicle's current operating condition information includes hybrid power system request information, gear information, motor fault information, and clutch status information.

[0144] The status determination module 920 can also be used to determine whether the motor is in an active state based on whether the hybrid power system request information contains one or more of the following: information used to characterize the operation of the control motor, gear information, and motor fault information. If the motor is determined to be in an active state, the motor state is determined based on whether the hybrid power system request information contains a clutch engagement request, gear information, and clutch status information. The motor state includes an enabled state, an disabled state, and a standby state.

[0145] In some embodiments of this disclosure, the vehicle's current operating condition information includes hybrid power system request information, driving cycle status information, door status information, seat belt status information, gear information, vehicle speed, and engine speed.

[0146] The state determination module 920 can also be used to determine that the vehicle is in a vehicle power-off enabled state when the hybrid system request information does not include an engine start request, the vehicle's driving cycle state is active, the vehicle speed is less than the target preset vehicle speed threshold, and the engine speed is less than the third speed threshold. When the vehicle is in a power-off enabled state, determine whether the vehicle meets the preset power-off trigger conditions. The preset power-off trigger conditions include: the door status information is that the driver's door is open, the gear information is that the gear is in the second gear, the seat belt status information is that the seat belt is unfastened, the duration of the gear information being in the second gear and the seat belt being unfastened is greater than a third preset duration threshold, the start-stop function is disabled, the engine starting is disabled, and the transmission control system is in a fault state. If the vehicle meets any one or more of the preset trigger conditions, the vehicle is determined to be in a power-off activated state.

[0147] In some embodiments of this disclosure, the engine state includes a stopped state, a running state, a stopped state, a starting state, and an abnormal stopped state.

[0148] The vehicle control module 930 can be specifically used to determine whether the motor is in an enabled state and whether the vehicle is in an activated state when powered down; when it is determined that the vehicle is in an inactive state when powered down and the motor is in an enabled state, the power state of the vehicle's hybrid system is switched based on the engine state. When it is determined that the vehicle is in an inactive state when the power is off and the engine is in a stopped state, the power state of the vehicle's hybrid system is switched based on the engine stop type and the motor state. Once it is determined that the vehicle is in an active state when it is powered off, the power state of the vehicle's hybrid system is switched to the powered-off state.

[0149] In some embodiments of this disclosure, the vehicle control device 900 may further include a start-stop function status determination module.

[0150] The start-stop function status determination module can be used to determine the start-stop function status of the vehicle based on the vehicle's current operating condition information before switching the power status of the vehicle's hybrid system based on the engine status, motor status, and vehicle power-off status.

[0151] The vehicle control module 930 can also be used to switch the power state of the vehicle's hybrid system based on the vehicle's start-stop function status, engine status, motor status, and vehicle power-off status.
