Description

Technical Field

[0001] This application relates to the field of hybrid vehicle control technology, and in particular to a vehicle parking and charging control method, device, computer equipment, and storage medium. Background Technology

[0002] Hybrid electric vehicles are an important branch of development in the current automotive field. Hybrid electric vehicles have the function of generating electricity using the engine. When the power battery in the hybrid electric vehicle is low, it can be recharged during parking time. Therefore, parking and charging is a typical working scenario for hybrid electric vehicles.

[0003] However, existing methods for charging hybrid vehicles while parked have the problem of battery depletion when the engine is used to charge the battery. Summary of the Invention

[0004] Therefore, it is necessary to provide a vehicle parking charging control method, device, computer equipment, and storage medium that can prevent the power battery from being depleted when the vehicle is parked and charging, in order to address the above-mentioned technical problems.

[0005] Firstly, this application provides a vehicle parking charging control method, applied to a P2 configuration hybrid electric vehicle. The method includes:

[0006] If any of the preset parking and charging conditions are met, the vehicle is controlled to enter the parking and charging state. The preset parking and charging conditions include the power battery charge in the vehicle being lower than a preset power charge threshold, receiving a handbrake command from the driver, the vehicle's gearbox being in neutral, and the vehicle's current speed being a preset speed threshold.

[0007] The preset parking and charging steps are executed sequentially, and the cumulative number of parking and charging failures is obtained in real time during the execution of the preset parking and charging steps. The initial value of the cumulative number is 0. The preset parking and charging steps are divided into clutch engagement stage, engine start stage, engine speed adjustment stage, motor torque adjustment stage and normal power generation stage.

[0008] If the cumulative number of times obtained in real time exceeds the preset threshold, the execution of the preset parking and charging steps will be interrupted, and the stage of the interruption node will be recorded.

[0009] In one embodiment, the execution process of the clutch engagement phase includes:

[0010] The clutch between the car engine and the car motor is controlled to engage within a preset engagement time by the vehicle controller or the transmission controller.

[0011] If the clutch fails to engage within the preset engagement time, the preset parking and charging steps are executed again sequentially, and the cumulative count is incremented by 1; if the clutch engages within the preset engagement time, the engine start phase continues.

[0012] In one embodiment, the execution process of the engine start-up phase includes:

[0013] The vehicle controller or the transmission controller controls the vehicle motor to adjust the vehicle engine to idle speed within a preset start-up time, so that the vehicle engine injects fuel to complete the engine start-up phase.

[0014] If the clutch slips, the clutch disengages, or the vehicle engine fails to reach the idle speed state within the preset start-up time, the preset parking and charging steps are executed again sequentially, and the cumulative count is incremented by 1; if the vehicle engine reaches the idle speed state within the preset start-up time, the engine speed adjustment phase continues.

[0015] In one embodiment, the execution process of the engine speed regulation phase includes:

[0016] The clutch controls the car motor to drive the car engine to reach the target power generation speed threshold within a preset speed adjustment time, and controls the torque of the car motor to be adjusted to a preset torque threshold.

[0017] If the clutch slips, the clutch disengages, the vehicle engine shuts down, or the vehicle engine fails to reach the target power generation speed threshold within the preset speed adjustment time, the preset parking and charging steps are executed again sequentially, and the cumulative number is incremented by 1; if the vehicle engine reaches the target power generation speed threshold within the preset speed adjustment time, the motor torque adjustment stage continues.

[0018] In one embodiment, the execution process of the motor torque adjustment phase includes:

[0019] The torque of the vehicle motor is controlled to reach the target power generation torque threshold within a preset torque adjustment time.

[0020] If the clutch slips, the clutch disengages, the vehicle engine shuts down, or the torque of the vehicle motor fails to reach the target power generation torque threshold within the preset torque adjustment time, the preset parking charging steps are executed again in sequence, and the cumulative number is incremented by 1; if the torque of the vehicle motor reaches the target power generation torque threshold within the preset torque adjustment time, the normal power generation phase continues.

[0021] In one embodiment, the execution process of the normal power generation phase includes:

[0022] The vehicle engine is controlled to generate electricity. If any of the preset conditions for stopping and charging are met, the vehicle engine is controlled to stop generating electricity. The preset conditions for stopping and charging include the power battery in the vehicle reaching a preset power generation completion threshold, receiving a driver's command to cancel the handbrake, and receiving a driver's command to select a gear.

[0023] If the clutch slips, the clutch disengages, or the vehicle engine shuts down, the preset parking and charging steps are executed again in sequence, and the cumulative number of times is incremented by 1.

[0024] Secondly, this application also provides a vehicle parking and charging control device for use in a P2 configuration hybrid vehicle. The device includes:

[0025] The status control module is used to control the car to enter the parking and charging state when any of the preset parking and charging conditions are met. The preset parking and charging conditions include the power battery charge in the car being lower than a preset power threshold, receiving a handbrake command from the driver, the car's gearbox being in neutral, and the car's current speed being a preset speed threshold.

[0026] The execution module is used to sequentially execute preset parking and charging steps, and during the sequential execution of the preset parking and charging steps, to obtain the cumulative number of parking and charging failures in real time. The initial value of the cumulative number is 0. The preset parking and charging steps are sequentially divided into clutch engagement stage, engine start stage, engine speed adjustment stage, motor torque adjustment stage and normal power generation stage.

[0027] The interrupt module is used to interrupt the execution of the preset parking and charging steps when the cumulative number of times obtained in real time exceeds a preset threshold, and to record the stage of the interrupted node.

[0028] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the steps of the methods in any of the above embodiments.

[0029] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, implements the steps of the methods in any of the above embodiments.

[0030] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, implements the steps of the methods in any of the above embodiments.

[0031] The aforementioned vehicle parking and charging control method, device, computer equipment, and storage medium control the vehicle to enter a parking and charging state when any of the preset parking and charging conditions are met, sequentially execute preset parking and charging steps, and during the sequential execution of the preset parking and charging steps, acquire the cumulative number of parking and charging failures in real time. If the cumulative number of failures exceeds a preset threshold, the execution of the preset parking and charging steps is interrupted, and the stage of the interruption is recorded. Compared with the problem of power battery depletion when the engine is used to charge the power battery in traditional technologies, this application ensures that each preset parking and charging step is completed sequentially by sequentially executing the preset parking and charging steps, which can prevent power battery depletion when the vehicle is parked and charging. When a preset parking and charging step fails to be executed successfully, the cumulative number of parking and charging failures is counted. If the cumulative number exceeds a preset threshold, the execution of the preset parking and charging steps can be interrupted to prevent energy waste caused by continuing to execute the preset parking and charging steps and avoid danger.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] This embodiment provides a vehicle parking and charging control method applied to a P2 configuration hybrid electric vehicle. This embodiment uses the application of this method to a computer device as an example for illustration. It is understood that this method can also be applied to a server, or to a system including a computer device and a server, and implemented through the interaction between the computer device and the server. Before describing the vehicle parking and charging control method in detail, let's first introduce the P2 configuration hybrid electric vehicle. A P2 configuration hybrid electric vehicle includes a vehicle engine, a clutch, a vehicle motor, a transmission, a vehicle control unit (VCU), and a transmission control unit (TCU). The clutch is located between the vehicle engine and the vehicle motor, the vehicle motor is connected to the transmission, and the VCU or TCU can control the vehicle engine, clutch, vehicle motor, and transmission.

[0038] Figure 1 This is a flowchart illustrating the vehicle parking and charging control method provided in this application embodiment. The method is applied in a computer device or server. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0039] S101, under any of the preset parking and charging conditions, control the car to enter the parking and charging state. The preset parking and charging conditions include the power battery charge in the car being lower than a preset charge threshold, receiving a handbrake command from the driver, the car's gearbox being in neutral, and the car's current speed being a preset speed threshold.

[0040] The preset power outage charging conditions are manually set conditions that allow the vehicle to charge while parked. The preset battery level threshold can also be manually set according to actual needs. The preset vehicle speed threshold is manually set and is usually set to 0.

[0041] S102, execute the preset parking charging steps in sequence, and during the execution of the preset parking charging steps, obtain the cumulative number of parking charging failures in real time. The initial value of the cumulative number is 0. The preset parking charging steps are divided into the clutch engagement stage, engine start stage, engine speed adjustment stage, motor torque adjustment stage and normal power generation stage in sequence.

[0042] The preset parking charging procedure is a set of steps for the vehicle to park and charge. This preset parking charging procedure is designed based on the structure of a P2 hybrid vehicle and ensures that it is executed sequentially to prevent the battery from being depleted while the vehicle is parked and charging.

[0043] S103, if the cumulative number of times obtained in real time is greater than the preset number threshold, the execution of the preset parking and charging steps will be interrupted, and the stage of the interrupted node will be recorded.

[0044] The vehicle parking charging control method provided in this embodiment controls the vehicle to enter a parking charging state when any of the preset parking charging conditions are met, and sequentially executes preset parking charging steps. During the sequential execution of the preset parking charging steps, the cumulative number of parking charging failures is acquired in real time. If the accumulated number exceeds a preset threshold, the execution of the preset parking charging steps is interrupted, and the stage of the interruption is recorded. Compared with the problem of power battery depletion when the engine is used to charge the power battery in traditional technology, this application ensures that each preset parking charging step is completed sequentially by executing the preset parking charging steps in sequence. This can prevent power battery depletion when the vehicle is parking and charging. When a preset parking charging step fails to be executed successfully, the cumulative number of parking charging failures is counted. If the cumulative number exceeds a preset threshold, the execution of the preset parking charging steps can be interrupted to prevent energy waste caused by continuing to execute the preset parking charging steps, avoid danger, protect the structural components inside the vehicle, and record the stage of the interruption so that the operator knows at which stage the interruption occurred.

[0045] In one embodiment, the execution process of the clutch engagement phase includes:

[0046] The clutch between the car engine and the car motor is controlled to engage within a preset engagement time by the vehicle controller or the transmission controller.

[0047] If the clutch fails to engage within the preset engagement time, the preset parking and charging steps will be executed again in sequence, and the cumulative number of times will be incremented by 1.

[0048] If the clutch engages within the preset engagement time, the engine start-up phase will continue.

[0049] The preset engagement time is set manually.

[0050] In this embodiment, clutch engagement enables the vehicle motor to subsequently drive the vehicle engine. After completing the engine start-up phase, if the clutch is still not engaged within a preset engagement time, it indicates that the vehicle is not suitable for entering the parking and charging state at this time, thus preventing the danger caused by continuing to engage the clutch.

[0051] In one embodiment, the execution process of the engine start-up phase includes:

[0052] The vehicle controller or transmission controller controls the car motor to adjust the car engine to idle speed within a preset start-up time, so that the car engine injects fuel to complete the engine start-up phase.

[0053] If the clutch slips, the clutch disengages, or the car engine fails to reach idle speed within the preset start-up time, the preset parking and charging steps will be executed again in sequence, and the cumulative number of times will be incremented by 1.

[0054] If the car engine reaches idle speed within the preset start-up time, the engine speed adjustment phase will continue.

[0055] The preset startup time is set manually.

[0056] In this embodiment, the car engine starts normally, ensuring that the subsequent engine speed adjustment stage is executed normally. If the car engine fails to start within the preset start time, it means that the car is not suitable for entering the parking charging state at this time. Furthermore, the failure to start the car engine indicates that parking charging cannot be achieved. Re-executing the preset parking charging steps can also avoid the dangers caused by forced parking charging.

[0057] In one embodiment, the execution process of the engine speed regulation phase includes:

[0058] The clutch controls the car motor to drive the car engine to reach the target power generation speed threshold within a preset speed adjustment time, and controls the torque of the car motor to be adjusted to the preset torque threshold.

[0059] If the clutch slips, the clutch disengages, the car engine stalls, or the car engine fails to reach the target power generation speed threshold within the preset speed adjustment time, the preset parking and charging steps will be executed again in sequence, and the cumulative number of times will be incremented by 1.

[0060] If the car engine reaches the target power generation speed threshold within the preset speed adjustment time, the motor torque adjustment phase will continue.

[0061] The preset speed adjustment duration is manually set. The target generator speed threshold is determined by the user based on the fuel consumption characteristics of the car engine and the efficiency characteristics of the car motor; it can be set as a single value or a range. The preset torque threshold is manually set and is usually set to 0.

[0062] In this embodiment, if the car engine does not reach the target power generation speed threshold within the preset speed adjustment time, energy may be wasted when the car is parked and charged. Reaching the target power generation speed threshold can prevent danger.

[0063] In one embodiment, the execution process of the motor torque adjustment phase includes:

[0064] Control the torque of the car motor to reach the target power generation torque threshold within a preset torque adjustment time;

[0065] If the clutch slips, the clutch disengages, the car engine shuts down, or the torque of the car motor fails to reach the target generating torque threshold within the preset torque adjustment time, the preset parking charging steps will be executed again in sequence, and the cumulative number of times will be incremented by 1.

[0066] If the torque of the car motor reaches the target power generation torque threshold within the preset torque adjustment time, the normal power generation phase will continue.

[0067] The preset torque adjustment duration is set manually. The target power generation torque threshold is determined by the user based on the fuel consumption characteristics of the car engine and the efficiency characteristics of the car motor; it can be set to a single value or a range.

[0068] In this embodiment, if the torque of the car motor does not reach the target power generation torque threshold within the preset torque adjustment time, energy may be wasted when the car is parked and charged. Reaching the target power generation torque threshold with the car motor can prevent danger.

[0069] In one embodiment, the execution process during the normal power generation phase includes:

[0070] Control the car engine to generate electricity. If any of the preset conditions for stopping and charging are met, control the car engine to stop generating electricity. The preset conditions for stopping and charging include the power battery in the car reaching the preset power generation completion threshold, receiving the driver's command to cancel the handbrake, and receiving the driver's command to select gears.

[0071] If the clutch slips, the clutch disengages, or the car engine stalls, the preset parking and charging steps will be executed again, and the accumulated number of times will be incremented by 1.

[0072] The preset power generation completion threshold can be set manually, according to actual needs.

[0073] In this embodiment, when the car engine is generating electricity, phenomena such as clutch slippage, clutch disengagement, and engine stalling may still occur. If the car fails to charge while parked, the preset parking charging steps must be executed again in sequence to avoid the danger of forced parking charging.

[0074] Here, the vehicle parking charging control method is described in detail with reference to a complete embodiment. See [link to documentation]. Figure 2 , Figure 2 A schematic diagram of a parking charging process for a vehicle is provided in one embodiment, including the following:

[0075] S201, if any of the preset parking and charging conditions are met, control the car to enter the parking and charging state.

[0076] S202, set a flag for the preset parking charging steps, and obtain the cumulative number of parking charging failures in real time. The initial value of the cumulative number is 0.

[0077] Specifically, the flag for the clutch engagement stage is set to 1, the flag for the engine start stage is set to 2, the flag for the engine speed adjustment stage is set to 3, the flag for the motor torque adjustment stage is set to 4, and the flag for the normal power generation stage is set to 5.

[0078] S203, clutch engagement phase.

[0079] In this embodiment, the clutch engagement phase is executed by controlling the clutch between the vehicle engine and the vehicle motor to engage within a preset engagement time through the vehicle controller or the transmission controller; if the clutch does not engage within the preset engagement time, step S203 is executed again and the cumulative count is incremented by 1; if the clutch engages within the preset engagement time, step S204 is executed again.

[0080] S204, Execute the engine start-up phase.

[0081] In this embodiment, the engine start-up phase is executed by controlling the vehicle controller or transmission controller to adjust the vehicle motor to idle speed within a preset start-up time, so that the vehicle engine injects fuel to complete the engine start-up phase. If the clutch slips, the clutch disengages, or the vehicle engine does not adjust to idle speed within the preset start-up time, step S203 is executed again, and the cumulative count is incremented by 1. If the vehicle engine reaches idle speed within the preset start-up time, step S205 is executed again.

[0082] S205, executing the engine speed regulation phase.

[0083] In this embodiment, the execution process of the engine speed adjustment stage is as follows: by using the clutch, the car motor drives the car engine to reach the target power generation speed threshold within a preset speed adjustment time, and the torque of the car motor is adjusted to the preset torque threshold. If the clutch slips, the clutch disengages, the car engine stalls, or the car engine fails to reach the target power generation speed threshold within the preset speed adjustment time, step S203 is executed again, and the cumulative count is incremented by 1. If the car engine reaches the target power generation speed threshold within the preset speed adjustment time, step S206 is executed again.

[0084] S206, execute the motor torque adjustment stage.

[0085] In this embodiment, the execution process of the motor torque adjustment stage is to control the torque of the car motor to reach the target power generation torque threshold within a preset torque adjustment time. If the clutch slips, the clutch disengages, the car engine shuts down, or the torque of the car motor does not reach the target power generation torque threshold within the preset torque adjustment time, then step S203 is executed again, and the cumulative count is incremented by 1. If the torque of the car motor reaches the target power generation torque threshold within the preset torque adjustment time, then step S207 is executed again.

[0086] S207, normal power generation phase.

[0087] In this embodiment, the execution process of the normal power generation phase is to control the car engine to generate electricity. If any of the preset stop charging conditions are met, the car engine is controlled to stop generating electricity. The preset stop charging conditions include the power of the car's internal power battery reaching a preset power generation completion threshold, receiving a driver's command to cancel the handbrake, and receiving a driver's command to select a gear. If the clutch slips, the clutch disengages, or the car engine shuts off, step S203 is executed again, and the accumulated count is incremented by 1.

[0088] S208, if the cumulative number of times obtained in real time is greater than the preset number threshold, the execution of the preset parking and charging steps will be interrupted, and the stage of the interrupted node will be recorded.

[0089] The vehicle parking charging control method provided in this embodiment ensures that each preset parking charging step is completed sequentially by executing preset parking charging steps in sequence. This prevents the power battery from being depleted when the vehicle is parked and charging. When a preset parking charging step is not successfully executed, the cumulative number of parking charging failures is counted. If the cumulative number exceeds a preset threshold, the execution of the preset parking charging step can be interrupted to prevent energy waste caused by continuing to execute the preset parking charging step, avoid danger, and protect the structural components inside the vehicle. The stage at which the interruption occurred is recorded so that the operator knows at which stage the interruption occurred. A flag bit for the preset parking charging step is set so that the corresponding stage can be known each time parking charging fails.

[0090] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0091] Based on the same inventive concept, this application also provides a vehicle parking and charging control device for implementing the vehicle parking and charging control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the vehicle parking and charging control device provided below can be found in the limitations of the vehicle parking and charging control method described above, and will not be repeated here.

[0092] See Figure 3 , Figure 3 This is a structural block diagram of a car parking and charging control device provided in an embodiment of this application. The device 300 is applied to a P2 configuration hybrid vehicle. The device 300 includes: a state control module 301, an execution module 302, and an interrupt module 303, wherein:

[0093] The state control module 301 is used to control the car to enter the parking and charging state when any of the preset parking and charging conditions are met. The preset parking and charging conditions include the power battery in the car being lower than a preset power threshold, receiving a handbrake command from the driver, the car's gearbox being in neutral, and the car's current speed being a preset speed threshold.

[0094] The execution module 302 is used to execute the preset parking charging steps in sequence, and during the process of executing the preset parking charging steps in sequence, the cumulative number of parking charging failures is obtained in real time. The initial value of the cumulative number is 0. The preset parking charging steps are divided into the clutch engagement stage, the engine start stage, the engine speed adjustment stage, the motor torque adjustment stage and the normal power generation stage in sequence.

[0095] The interrupt module 303 is used to interrupt the execution of the preset parking and charging steps and record the stage of the interrupted node when the cumulative number of times obtained in real time exceeds the preset number threshold.

[0096] The vehicle parking charging control device provided in this embodiment controls the vehicle to enter a parking charging state when any of the preset parking charging conditions are met, and sequentially executes preset parking charging steps. During the sequential execution of these steps, the device continuously monitors the cumulative number of parking charging failures. If the cumulative number exceeds a preset threshold, the execution of the preset parking charging steps is interrupted, and the stage of the interruption is recorded. Compared to traditional technologies where the power battery may become depleted when the engine charges the battery, this application ensures that each preset parking charging step is completed sequentially by executing the preset parking charging steps sequentially. This prevents the power battery from becoming depleted during vehicle parking charging. Furthermore, it counts the cumulative number of parking charging failures when a preset parking charging step fails. If the cumulative number exceeds a preset threshold, the execution of the preset parking charging steps is interrupted to prevent energy waste caused by continuing and to avoid potential danger.

[0097] Optionally, execution module 302 includes:

[0098] The clutch engagement stage execution unit is used to control the clutch between the vehicle engine and the vehicle motor to engage within a preset engagement time through the vehicle controller or the transmission controller; if the clutch does not engage within the preset engagement time, the preset parking and charging steps are executed again in sequence, and the cumulative count is incremented by 1; if the clutch engages within the preset engagement time, the engine start stage is executed again.

[0099] Optionally, execution module 302 includes:

[0100] The engine start-up stage execution unit is used to control the vehicle's electric motor to adjust the vehicle's engine to idle speed within a preset start-up time through the vehicle controller or transmission controller, so that the vehicle's engine injects fuel to complete the engine start-up stage; if the clutch slips, the clutch disengages, or the vehicle's engine fails to adjust to idle speed within the preset start-up time, the preset parking and charging steps are executed again in sequence, and the cumulative number is incremented by 1; if the vehicle's engine reaches idle speed within the preset start-up time, the engine speed adjustment stage continues.

[0101] Optionally, execution module 302 includes:

[0102] The engine speed regulation stage execution unit is used to control the car motor to drive the car engine to reach the target power generation speed threshold within a preset speed regulation time through the clutch, and to control the torque of the car motor to adjust to the preset torque threshold. If the clutch slips, the clutch disengages, the car engine stalls, or the car engine fails to reach the target power generation speed threshold within the preset speed regulation time, the preset parking and charging steps are executed again in sequence, and the cumulative number is incremented by 1. If the car engine reaches the target power generation speed threshold within the preset speed regulation time, the motor torque adjustment stage continues.

[0103] Optionally, execution module 302 includes:

[0104] The motor torque adjustment stage execution unit is used to control the torque of the car motor to reach the target power generation torque threshold within a preset torque adjustment time. If the clutch slips, the clutch disengages, the car engine shuts down, or the torque of the car motor fails to reach the target power generation torque threshold within the preset torque adjustment time, the preset parking charging steps are executed again in sequence, and the cumulative number is incremented by 1. If the torque of the car motor reaches the target power generation torque threshold within the preset torque adjustment time, the normal power generation stage continues.

[0105] Optionally, execution module 302 includes:

[0106] The normal power generation stage execution unit is used to control the car engine to generate electricity. If any of the preset stop charging conditions are met, the car engine will be controlled to stop generating electricity. The preset stop charging conditions include the power battery in the car reaching the preset power generation completion threshold, receiving the driver's command to cancel the handbrake, and receiving the driver's command to select gears. If the clutch slips, the clutch disengages, or the car engine shuts off, the preset stop charging steps will be executed again in sequence, and the cumulative number will be incremented by 1.

[0109] Those skilled in the art will understand that Figure 4 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0110] In one embodiment, a computer device is provided, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the steps of the vehicle parking and charging control method provided in the above embodiment.

[0111] If any of the preset parking and charging conditions are met, the vehicle is controlled to enter the parking and charging state. The preset parking and charging conditions include the power battery charge being lower than a preset charge threshold, receiving a handbrake command from the driver, the vehicle's gearbox being in neutral, and the vehicle's current speed being a preset speed threshold.

[0112] The preset parking charging steps are executed sequentially, and the cumulative number of parking charging failures is obtained in real time during the execution of the preset parking charging steps. The initial value of the cumulative number is 0. The preset parking charging steps are divided into clutch engagement stage, engine start stage, engine speed adjustment stage, motor torque adjustment stage and normal power generation stage.
