Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure.

[0019] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.
[0020] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".
[0021] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.
[0022] In order to solve the above problems, the embodiment of the present disclosure provides a vehicle charging processing method, in which the power generated during regeneration is used efficiently, wherein carbon particles are generated during the engine fuel process, and carbon particles are particulate matter left over from insufficient mixing of air and fuel when the engine is working. The regeneration of the embodiment of the present disclosure includes parking regeneration, etc., wherein parking regeneration refers to an emission control system that requires the vehicle to stop and press the regeneration switch on the vehicle when the carbon load reaches a certain level during driving. This regeneration method requires the addition of an electronic control system and a catalyst, and the carbon soot adsorbed on the metal fiber felt particles is burned by combustion, and converted into harmless carbon dioxide and discharged into the atmosphere.
[0023] Among them, during the vehicle regeneration process, both diesel engines and gasoline engines meet the over-emission regulations, especially engines with parking regeneration or driving regeneration. In the case of parking regeneration, the engine speed will reach about 2500rpm or 3000rpm. At this time, the engine consumes more fuel, and in order to discharge the carbon particles in the particulate filter as soon as possible, the emission temperature needs to be raised to more than several hundred degrees. This part of the regeneration energy is relatively large. Therefore, in the technical solution disclosed in the present invention, the energy in the regeneration process is fully utilized and the generated power during regeneration is used efficiently to make the whole vehicle more energy-efficient.
[0024] The method is introduced below in conjunction with specific embodiments.
[0025] Figure 1 The present invention provides a flow chart of a vehicle charging processing method provided by an embodiment of the present invention. The method can be executed by a vehicle charging processing device, wherein the device can be implemented by software and / or hardware, and can generally be integrated in a vehicle control device, which can include a vehicle control unit (VCU), etc. Figure 1 As shown, the method includes:
[0026] Step 101, detecting whether the vehicle currently meets the preset regeneration conditions.
[0027] The preset regeneration condition may be at least one of the following, that is, the following embodiments may be used as a preset regeneration condition individually or in combination as preset regeneration conditions, etc. The examples are as follows:
[0028] In some possible examples, the power level of the vehicle's power battery is less than a first power level threshold, wherein the first power level threshold may be determined according to the specific configuration of the vehicle, etc. Generally, when the power level of the vehicle's power battery is less than the first power level threshold, the vehicle may switch to a hybrid mode to start the engine in a hybrid series mode to drive the generator to generate electricity and charge the power battery, so that when the power level of the vehicle's power battery is less than the first power level threshold, it is determined that the vehicle meets the preset regeneration condition.
[0029] In some possible embodiments, if the vehicle starts the preset off-vehicle discharge function, it is determined that the vehicle meets the preset regeneration condition when the preset off-vehicle discharge function is in operation. In some possible examples, the carbon emissions of the vehicle are greater than the preset emission threshold, wherein the preset emission threshold is the value at which the current carbon load reaches the limit value requiring regeneration and the regeneration is required, and the preset emission threshold can be set according to the configuration of the vehicle, etc.
[0030] In some possible examples, it is determined whether the last regeneration of the engine is completed. If it is in an incomplete state, it is determined that the corresponding preset regeneration conditions are met. For example, during the last cycle of the engine, the carbon emissions detected were greater than the preset emission threshold, thereby initiating regeneration. However, the user may have turned off the engine before the regeneration process was completed, resulting in an inability to regenerate the terminal, and thus, the regeneration was incomplete. In this case, the engine is always in a regeneration preparation state, and it is always considered that the preset regeneration conditions are met.
[0031] As mentioned above, the preset regeneration conditions in the above-mentioned examples can be implemented separately or in combination. For example, as a combined implementation, when the power of the vehicle's power battery is less than the first power threshold, if it is detected that the preset off-vehicle discharge function is started, that is, the preset off-vehicle discharge function is in operation, it is considered that the preset regeneration condition is met. Step 102, when the preset regeneration condition is met, it is determined whether the preset off-vehicle discharge function of the vehicle is in operation.
[0032] Among them, the preset vehicle to load (V2L) discharge function can be used for external discharge, which is convenient for customers to drive for picnics or use the power in the power battery through V2L in special circumstances for emergency use, such as boiling water, cooking, etc.
[0033] Since V2L consumes a lot of power, when the preset regeneration conditions are met, it is determined whether the preset off-vehicle discharge function of the vehicle is in operation so as to give priority to powering V2L.
[0034] Step 103, when the preset off-vehicle discharge function is in operation, control the engine to regenerate.
[0035] Step 104 , during regeneration, power is supplied to the preset off-vehicle discharge function according to the power generated by the engine.
[0036] In one embodiment of the present disclosure, when the preset off-vehicle discharge function is in operation, the engine is controlled to regenerate, and during the regeneration process, the preset off-vehicle discharge function is powered according to the engine's generated power. That is, in this embodiment, the regenerated generated power is directly used for power supply, and the power is preferentially provided to V2L for use. This eliminates the need for efficient conversion through charging and discharging of the power battery, and has a higher power utilization rate.
[0037] In one embodiment of the present disclosure, in order to enhance the sense of interaction, a regeneration charging notification message may be sent to a preset terminal device before powering the preset off-vehicle discharge function, wherein the preset terminal device includes a mobile phone, etc., and the regeneration charging notification message includes but is not limited to one or more of text, pattern, animation, voice, etc. The regeneration charging notification message is used to notify the user that regeneration charging can be performed at present, and the user can confirm the regeneration charging notification message on the terminal device, thereby obtaining the confirmation instruction of the regeneration charging notification message sent by the terminal device, and after obtaining the confirmation instruction, the preset off-vehicle discharge function is powered according to the power generation power of the engine. In this embodiment, the user can manually determine whether the current vehicle is suitable for regeneration according to the regeneration charging notification message, for example, in the parking regeneration scenario, whether the vehicle is parked, etc. If it is suitable for regeneration, the regeneration charging notification message is confirmed.
[0038] In one embodiment of the present disclosure, it is also possible to automatically determine whether the vehicle is suitable for regeneration. If it is suitable for regeneration, the preset off-vehicle discharge function is powered according to the power generation power of the engine when the vehicle is regenerating.
[0039] In this embodiment, multiple control elements associated with the vehicle and the parking mode can be determined, wherein the multiple control elements include a vehicle output shaft, an accelerator pedal, a handbrake, a transmission gear, a transmitter, a motor, a power battery, etc. In this embodiment, multiple element operating parameters corresponding to the multiple control elements are obtained, and it is determined that the vehicle meets the regeneration safety conditions based on the multiple element operating parameters.
[0040] When the vehicle meets the regeneration safety conditions, it is considered that the vehicle can be regenerated and charged, etc., wherein the above-mentioned component operating parameters correspond to the control unit. The following is an example of determining the preset regeneration safety conditions using the control components including the vehicle output shaft, accelerator pedal, handbrake, transmission gear, transmitter, motor, power battery, etc.: In this embodiment, the speed (component operating parameter) corresponding to the vehicle speed and the output shaft speed is obtained. When the speed corresponding to the vehicle speed and the output shaft speed is 0, and when it is determined that the vehicle speed signal sent by the output shaft speed sensor and the ABS control is valid, it is determined whether the accelerator pedal opening (component operating parameter) is 0 and the accelerator pedal signal is valid. If the accelerator pedal opening is 0, the state of the electronic parking system or the handbrake (component operating parameter) is further determined. When the vehicle is in the parking state, the current state (component operating parameters) of the motor or controller is further determined to be free of faults. If so, the vehicle's onboard charger or power battery is determined to be free of faults. If so, the vehicle meets the regeneration safety conditions.
[0041] In this embodiment, there is no need for the user to actively determine whether the vehicle can be regenerated. In this embodiment, in order to enhance the sense of interactivity, after determining that the vehicle meets the regeneration safety conditions, a regeneration charging prompt message can also be sent to the corresponding terminal device. For example, a prompt message of "parking regeneration power generation mode is in progress" is sent to the terminal device.
[0042] Among them, in this embodiment, it is possible to monitor in real time whether the vehicle meets the preset safety regeneration conditions. Once it is not met, a regeneration charging mode is proposed to ensure the safety of the vehicle and to ensure parking regeneration without faults.
[0043] In another embodiment of the present disclosure, after determining whether a preset off-vehicle discharge function of the vehicle is in operation, it is also possible to choose to charge the power battery to avoid wasting regenerative energy.
[0044] In this embodiment, if Figure 2 As shown, after determining whether the preset off-vehicle discharge function of the vehicle is in an operating state, it also includes:
[0045] Step 201, when the preset off-vehicle discharge function is not in operation, control the engine to regenerate.
[0046] Step 202, charging the power battery in the vehicle according to the power generated by the engine during regeneration.
[0047] In one embodiment of the present disclosure, before charging the power battery in the vehicle according to the power generation power of the engine during regeneration, a regeneration charging notification message may also be sent to a preset terminal device. After obtaining a confirmation instruction for the regeneration charging notification message sent by the terminal device, the power battery in the vehicle is charged based on the energy generated during the regeneration process.
[0048] In this embodiment, when the preset off-vehicle discharge function is not in operation, the engine is controlled to regenerate, and during regeneration, the power battery in the vehicle is charged according to the power generated by the engine, thereby recovering the energy generated during the regeneration process and improving the energy efficiency of the entire vehicle. In this embodiment, the charging function can be performed by closing the charging clutch or the like.
[0049] In one embodiment of the present disclosure, if the power battery is fully charged and the preset off-vehicle discharge function is not in operation, the charging function is stopped and only regeneration is performed. In this embodiment, the charging function can be stopped by disconnecting the charging clutch or the like.
[0050] In this embodiment, if the power battery is being charged and it is detected that the preset off-vehicle discharge function is in operation, the preset off-vehicle discharge function can be powered directly according to the power generation power of the engine during regeneration.
[0051] In one embodiment of the present disclosure, if it is detected that the preset off-vehicle discharge function is switched from the running state to the off state when the preset off-vehicle discharge function is powered, then in response to the preset off-vehicle discharge function being switched from the running state to the off state, the remaining power generation of the regeneration is calculated, for example, the regeneration speed, regeneration torque and remaining regeneration time of the engine can be obtained, wherein the remaining regeneration time can be obtained based on the total regeneration consumption time minus the regeneration execution time, and the preset charging efficiency is obtained, wherein the charging efficiency can be obtained by querying a database according to the vehicle model, etc., and the preset database contains the corresponding relationship between different vehicle signals and corresponding charging efficiencies, and then, the regeneration speed, regeneration torque, remaining regeneration time and charging efficiency are multiplied to obtain the remaining power generation, etc. The remaining power generation can be understood as the power generation available for parking regeneration.
[0052] After obtaining the remaining power generation, the current remaining power of the power battery is calculated. For example, the current remaining power can be detected by the VCU to determine whether the current remaining power is less than the first power threshold. When it is less than the first power threshold, the power battery is charged according to the remaining power generation. The first preset power threshold may correspond to the remaining power value of the power battery, or may correspond to the remaining power ratio of the power battery. For example, when the first preset power threshold corresponds to the remaining power ratio of the power battery, the first preset power threshold may be 56.4%. In some possible embodiments, if the estimated remaining power generation of the engine is 7.85 kwh, and the current remaining power of the power battery is less than 56.4% of the vehicle, the power battery is charged. Thus, the regenerated energy is further recovered and stored in the power battery, and parking regeneration at this time can prevent the power battery from being insufficient in the driving mode during driving, or the power battery is insufficient in the hybrid mode when driving at low speed, thereby reducing the driving experience of the hybrid vehicle, ensuring sufficient power during driving, and improving the energy saving effect of the vehicle.
[0053] In one embodiment of the present disclosure, if the current remaining power is not less than the first preset power threshold, it indicates that the normal power generation mode can be used for power generation, and the regenerative energy may not be recovered.
[0054] In other possible embodiments, when it is determined that the current remaining power is less than the first power threshold, it can be further determined whether the remaining power generation is greater than the second power threshold, wherein the second power threshold is a relatively small value. If the remaining power generation is not greater than the second power threshold, it indicates that it is not sufficient to charge the power battery to a power level greater than the first power threshold. Therefore, in this embodiment, when the remaining power generation is greater than the second power threshold, the power generation is utilized, and the power battery in the vehicle is charged according to the power generation power of the engine during regeneration.
[0055] In one embodiment of the present disclosure, when the current remaining power is not less than the first power threshold, it is considered that the power battery has sufficient power and there is no need to perform parking regeneration, so regeneration is performed instead of regenerative charging, etc.; or, when the current remaining power is less than the first power threshold, but the remaining power generation is not greater than the second power threshold, it is considered that the current remaining power generation is small and is not sufficient to charge the power battery to a power level greater than the first power threshold. At this time, the generator is driven to perform normal charging processing to ensure that the power of the power battery can reach above the first power threshold as soon as possible, etc., to avoid affecting the normal driving of the vehicle.
[0056] In one embodiment of the present disclosure, the opportunity can also be seized to pre-charge the power battery. For example, the average power generation of the power battery when using the V2L function can be detected, and the remaining time for the current power battery to reach the first power threshold can be determined based on the average power generation. If the remaining time is less than the preset time threshold, it is determined whether the carbon load at this time reaches the preset emission reference threshold, wherein the preset emission reference threshold is a relatively large value less than the preset emission threshold. If the carbon load at this time is greater than or equal to the preset emission reference threshold, it is determined that the preset regeneration condition is currently met, and the engine is controlled in advance to perform regenerative combustion of the carbon load, and during the regeneration process, the V2L is powered on, etc.
[0057] In summary, the vehicle charging processing method of the disclosed embodiment detects whether the vehicle currently meets the preset regeneration conditions. If the preset regeneration conditions are met, it determines whether the preset external discharge function of the vehicle is in operation. When the preset external discharge function is in operation, the engine is controlled to regenerate. When regenerating, the preset external discharge function is powered according to the power generated by the engine. In this technical solution, the power generated during regeneration is efficiently utilized to achieve energy saving of the entire vehicle.
