Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and particularly to a vehicle heating control system, method and storage medium that meet the demand of electrical balance. Background Art

[0002] In the era of vehicle electrification, the on-vehicle power supply device DCDC provides energy for all electrical devices during normal operation. Under certain extreme working conditions, such as on a rainy and snowy night in winter or a rainy night in summer, all electrical devices of the vehicle need to be turned on to meet the needs of users. Among them, the rear windshield and rearview mirror heating and defogging devices are one of the high-power electrical devices. Since the rear windshield and rearview mirror are generally turned on simultaneously, they share an enable and disable switch button. The activation time of the rear windshield and rearview mirror heating and defogging functions varies with the ambient temperature. The higher the ambient temperature, the shorter the heating time; the lower the ambient temperature, the relatively longer the heating time. Whether the power of DCDC can meet the demand for simultaneous activation of all high-power electrical devices under extreme working conditions is an important performance indicator for the electrical balance of the whole vehicle.

[0003] To meet the demand for electrical balance performance under the above extreme working conditions, when some vehicle manufacturers select the DCDC power supply device, they will select a DCDC device that matches it according to the power required to turn on all electrical devices under extreme working conditions. For example, under extreme working conditions, if the power of all electrical devices of the whole vehicle is 2.8KW, a DCDC power supply device with a high power of 3.0KW or 3.3KW can be selected.

[0004] Although the above technical solutions solve the problem of electrical balance performance, the cost of high-power DCDC is relatively high; at the same time, such extreme working conditions are not common or occur less frequently, so the energy consumption required under non-extreme working conditions is relatively small, and such a high-power DCDC seems to have excessive energy.

[0005] For some models with more functions, the number of high-power electrical devices also increases. If the power of the configured DCDC device cannot meet the requirements, the vehicle power demand can only be reduced by means of load shedding. Here, load shedding means that the central brain of the whole vehicle directly cuts off some high-power electrical devices, such as cutting off the rear windshield and rearview mirror heating and defogging functions.

[0006] The rear windshield and rearview mirror belong to the field of vehicle functional safety. Once the power supply of this function is directly cut off, it will pose a safety hazard to the driver's driving under poor external climate and conditions. Summary of the Invention

[0007] The purpose of this application is to solve the deficiencies of the above background art and provide a vehicle heating control system, method and storage medium that meet the demand of electrical balance.

[0008] The technical solution of this application is: An automotive heating control system that meets the electrical balance requirement, including,

[0009] A start time recording module, which is used to record the activation time of the rear windshield and rearview mirror heating and defogging functions;

[0010] An initial condition judgment module, which is used to make a judgment of meeting the initial conditions when the rear windshield and rearview mirror heating and defogging switch is pressed and the DCDC power is insufficient, otherwise it makes a judgment of not meeting the initial conditions;

[0011] A control module, which is used to compare the activation time with the set time after meeting the initial conditions and receiving an unloading request, and issue an instruction to continue activating the rear windshield and rearview mirror heating and defogging functions, pause activating the rear windshield and rearview mirror heating and defogging functions, or turn off the activation of the rear windshield and rearview mirror heating and defogging functions according to the comparison result.

[0012] According to an automotive heating control system that meets the electrical balance requirement provided by this application, the control module includes,

[0013] A first instruction module, which is used to issue an instruction to continue activating the rear windshield and rearview mirror heating and defogging functions when the activation time is less than the first preset time.

[0014] According to an automotive heating control system that meets the electrical balance requirement provided by this application, the control module includes,

[0015] A second instruction module, which is used to issue an instruction to pause activating the rear windshield and rearview mirror heating and defogging functions when the activation time is not less than the first preset time.

[0016] According to an automotive heating control system that meets the electrical balance requirement provided by this application, the control module further includes,

[0017] A pause time recording module, which is used to record the duration of the pause activation as the pause time;

[0018] A third instruction module, which is used to issue an instruction to reactivate the rear windshield and rearview mirror heating and defogging functions when the pause time is less than the second preset time and the unloading request is cancelled during the pause time, otherwise it issues an instruction to continue pausing the activation of the rear windshield and rearview mirror heating and defogging functions.

[0019] According to an automotive heating control system that meets the electrical balance requirement provided by this application, the control module further includes,

[0020] A fourth instruction module, which is used to issue an instruction to turn off the activated rear windshield and rearview mirror heating and defogging functions when the pause time is equal to the second preset time and the unloading request persists during the pause time.

[0021] According to an automotive heating control system that meets the electrical balance requirement provided by the present application, the first preset time is a preset time that is a times the default time; the default time is the time from the normal activation of the rear windshield and rearview mirror heating and defogging to the completion of defogging and shutdown; a is greater than 0 and less than 1.

[0022] According to an automotive heating control system that meets the electrical balance requirement provided by the present application, the control module further includes,

[0023] A fifth instruction module, which is used to turn off the activated rear windshield and rearview mirror heating and defogging functions when the activation time reaches the default time.

[0024] According to an automotive heating control system that meets the electrical balance requirement provided by the present application, the second preset time is 60s - 120s.

[0025] The present application also relates to an automotive heating control method that meets the electrical balance requirement, including,

[0026] Recording the activation time of the rear windshield and rearview mirror heating and defogging switch;

[0027] Judging whether the current state meets the initial condition that the rear windshield and rearview mirror heating and defogging switch is pressed and the DCDC power is insufficient;

[0028] If the initial condition is met and an unloading request is received, comparing the activation time with the set time;

[0029] If the activation time is less than the first preset time, continue to activate the rear windshield and rearview mirror heating and defogging functions, otherwise pause the activation of the rear windshield and rearview mirror heating and defogging functions;

[0030] If the activation is paused, record the pause time. If the pause time is less than the second preset time and the unloading request is cancelled during the pause time, reactivate the rear windshield and rearview mirror heating and defogging functions. If the pause time is equal to the second preset time, turn off the activated rear windshield and rearview mirror heating and defogging functions.

[0031] The present application also relates to a non-transitory computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the above-mentioned automotive heating control method that meets the electrical balance requirement are implemented.

[0032] The advantages of this application are as follows: 1. The vehicle heating control system of this application can fully consider the heating requirements of the rear windshield and rearview mirrors under extreme working conditions. On the one hand, it does not need to consider the power requirements of electrical equipment under extreme working conditions. Instead, it only needs to select a DCDC model with a moderate power by combining the calculated values of the power requirements of electrical equipment under relatively common working conditions, avoiding the blind use of high-power DCDC, reducing the vehicle cost, and at the same time ensuring the optimal energy utilization rate of DCDC. On the other hand, when there is an unloading request for the vehicle, when the control module still cannot meet the vehicle's electrical balance requirements after giving priority to turning off the functions of high-power electrical equipment with comfort attributes of the vehicle, the control module will then select some other large electrical equipment for unloading, that is, the rear windshield and rearview mirror heating and defogging functions can also support the vehicle's electrical balance under extreme working conditions, ensuring the safety of vehicle driving;

[0033] 2. When the activation time is less than the first preset time, this application will not immediately turn off or suspend the rear windshield and rearview mirror heating and defogging functions. This is because the current heating time is short. If the heating and defogging functions are directly turned off, it is very likely to cause safety accidents. Therefore, it is urgent to maintain the rear windshield and rearview mirror heating and defogging functions to ensure the safety of vehicle driving;

[0034] 3. When the activation time is not less than the first preset time and the unloading request still exists, it can be determined at this time that the activation time is long, that is, the rear windshield and rearview mirrors have been heated and defogged for a period of time and should have had a certain effect. If there is still an unloading request at this time, it proves that the pressure on the DCDC is relatively large at this time. The rear windshield and rearview mirror heating and defogging functions can be suspended to maintain the electrical balance of the DCDC without causing safety hazards;

[0035] 4. This application records the suspension time and compares it with the second preset time. If the unloading request is not required during the suspension period, it proves that the rear windshield and rearview mirror heating and defogging functions can be restored at present, so as to facilitate the timely heating and defogging of the rear windshield and rearview mirrors. Such a design has a rapid response, does not require the operation of the driver and passengers, and is simple and convenient;

[0036] 5. By comparing the suspension time with the second time, if the suspension time exceeds the second preset time and the unloading request still exists, it proves that the load pressure on the DCDC is very large at this time, and only the rear windshield and rearview mirror heating and defogging can be turned off to maintain the electrical balance of the DCDC, improving the stability of the vehicle's electrical load;

[0037] 6. The first preset time of this application is determined based on the default time. The default time is the time from the normal opening of the rear windshield and rearview mirror heating and defogging to the completion of defogging and closing. This can ensure that the running time of the heating and defrosting functions is appropriate, neither too long nor too short, within a proper range, and the subsequent control and adjustment are more reasonable;

[0038] 7. When the activation time of this application reaches the default time, regardless of whether this activation time is accumulated multiple times, as long as the default time is reached, the heating and defogging of the rear windshield and rearview mirror can be stopped. At this time, it is considered that the heating and defogging of the rear windshield and rearview mirror have been completed, avoiding further waste of energy and also being able to reduce the load pressure on the DCDC;

[0039] 8. This application sets the second preset time. By setting the second preset time, the time for pausing the activation of the heating and defogging of the rear windshield and rearview mirror can be limited, ensuring the electrical balance of the DCDC device and also facilitating subsequent further judgment on whether to turn off this function;

[0040] 9. This application also relates to an automobile heating control method that meets the electrical balance requirements. The control method of this application is simple and easy to operate, and can control the heating and defogging functions of the rear windshield and rearview mirror, which can not only ensure safety but also avoid the problem of damaging the DCDC electrical balance.

[0041] The control system of this application has a simple structure and is convenient to operate. It can reduce the cost of the whole vehicle and also ensure the optimal utilization rate of DCDC energy. The heating and defogging functions of the rear windshield and rearview mirror can also support the electrical balance of the whole vehicle under extreme working conditions, ensuring the driving safety of the vehicle and having great promotion value.

In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0046] The following further elaborates on this application in conjunction with the accompanying drawings and specific embodiments.

[0047] This application relates to an automotive heating control system that meets the demand for electrical balance. The heating control system of this application is mainly used to control the functions of heating and defogging the rear windshield and rearview mirrors. The functions of heating and defogging the rear windshield and rearview mirrors mainly utilize the heat generated after the heating wires installed in the rear windshield and rearview mirrors are electrified to remove rain, fog, ice, frost, etc. attached to the rear windshield and rearview mirrors. The power of heating and defogging the rear windshield and rearview mirrors is relatively large, and it belongs to high-power electrical equipment in the automotive power system. If in extreme weather conditions, such as on a rainy and snowy night in winter or a rainy night in summer, when all electrical equipment in the vehicle is turned on and all loads are in the maximum mode, such as the maximum blower speed, the lowest or highest air conditioning temperature, the maximum steering torque, the highest energy consumption of the braking system, etc., and the functions of heating and defogging the rear windshield and rearview mirrors are also in the maximum power on state, it may lead to insufficient DCDC power. In order to maintain electrical balance, it is necessary to turn off some high-power electrical equipment. This application is to explore a method for controlling the functions of heating and defogging the rear windshield and rearview mirrors. While ensuring the maximum degree of maintaining safe driving, maintain the electrical balance of the DCDC.

[0048] Specifically, a vehicle heating control system that meets the electrical balance requirement of the present application includes a startup time recording module, an initial condition judgment module, and a control module. The startup time recording module is used to record the activation time of the rear windshield and rearview mirror heating and defogging functions. The activation time refers to the duration after the rear windshield and rearview mirror heating and defogging functions are activated and turned on, that is, the actual operating time of the rear windshield and rearview mirror heating and defogging functions. The initial condition judgment module is used to make a judgment on whether the initial conditions are met when the rear windshield and rearview mirror heating and defogging switch is pressed and the DCDC power is insufficient; otherwise, it makes a judgment that the initial conditions are not met. The judgment of the initial conditions is to determine whether it is necessary to adjust the rear windshield and rearview mirror heating and defogging functions subsequently, whether the current situation is extreme, whether there is a problem of insufficient DCDC power, and whether it is necessary to adjust the rear windshield and rearview mirror heating and defogging functions to achieve the purpose of maintaining electrical balance. The control module is used to compare the activation time with the set time after the initial conditions are met and a unloading request is received, and issue an instruction to continue activating the rear windshield and rearview mirror heating and defogging functions, pause activating the rear windshield and rearview mirror heating and defogging functions, or turn off the activation of the rear windshield and rearview mirror heating and defogging functions according to the comparison result.

[0049] The adjustment of the rear windshield and rearview mirror heating and defogging functions includes multiple aspects: pausing activation, continuing activation, and turning off the activation of the rear windshield and rearview mirror heating and defogging functions. Continuing to activate the rear windshield and rearview mirror heating and defogging functions means maintaining the activation state of the rear windshield and rearview mirror heating and defogging functions, and the rear windshield and rearview mirror continue to be heated and defogged. This state is mainly considered because the heating and defogging time is short, and there may be a large amount of water mist and ice on the rear windshield and rearview mirror. If the heating and defrosting are stopped, there may be safety hazards. Therefore, it is necessary to continue to maintain the rear windshield and rearview mirror heating and defogging functions. Pausing the activation of the rear windshield and rearview mirror heating and defogging functions means that the on button for the rear windshield and rearview mirror heating and defogging functions is currently pressed, but the rear windshield and rearview mirror heating and defogging functions are paused, and the heating wires in the rear windshield and rearview mirror are not energized to generate heat. Whether further operations are required in the future needs further judgment. Turning off the activation of the rear windshield and rearview mirror heating and defogging functions means directly turning off the rear windshield and rearview mirror heating and defogging functions.

[0050] During actual control, as Figure 1 shown, the following method is adopted:

[0051] S1. Record the activation time of the rear windshield and rearview mirror heating and defogging switch;

[0052] S2. Determine whether the current state meets the initial conditions of the rear windshield and rearview mirror heating and defogging switch being pressed and the DCDC power being insufficient;

[0053] S3. If the initial conditions are met and an unloading request is received, compare the activation time with the set time, and based on the comparison result, issue an instruction to continue activating the rear windshield and rearview mirror heating and defogging functions, pause the activation of the rear windshield and rearview mirror heating and defogging functions, or turn off the activation of the rear windshield and rearview mirror heating and defogging functions.

[0054] In some embodiments of the present application, this embodiment optimizes the above control module. Specifically, the control module includes a first instruction module, and the first instruction module is used to issue an instruction to continue activating the rear windshield and rearview mirror heating and defogging functions when the activation time is less than the first preset time.

[0055] In this embodiment, when the activation time is less than the first preset time, that is, the activation time T0 < the first preset time T1, at this time, the duration of the rear windshield and rearview mirror heating and defogging functions is relatively short, and there may still be a lot of rain, fog, ice, and frost on the rear windshield and rearview mirror. If the rear windshield and rearview mirror heating and defogging functions are stopped at this time, it may cause relatively serious safety hazards. Therefore, when this situation occurs, although the DCDC already has a requirement to unload the load, the rear windshield and rearview mirror heating and defogging functions still need to be maintained at this time.

[0056] The first preset time T1 is a times the default time T a of the preset time, and the default time T a is the time from the normal start of the rear windshield and rearview mirror heating and defogging to the completion of defogging and closing. a is greater than 0 and less than 1. In this embodiment, a can be 0.5, and the default time T a can be 10 min, that is, the first preset time T1 is 5 min at this time. In actual applications, it is not limited to the above values and can be selected according to actual needs.

[0057] The default time T a is determined based on the current ambient temperature and refers to the time from the start of the rear windshield and rearview mirror heating and defogging functions to the rear windshield and rearview mirror reaching complete defrosting. This can be obtained through a calibration test, and the obtained comparison relationship table is stored in the controller for convenient calling at any time.

[0058] In some other embodiments of the present application, this embodiment further optimizes the above control module. Specifically, the control module includes a second instruction module, and the second instruction module is used to issue an instruction to pause the activation of the rear windshield and rearview mirror heating and defogging functions when the activation time is not less than the first preset time.

[0059] In this embodiment, when the activation time is not less than the first preset time, that is, the activation time T0 ≥ the first preset time T1 but < the default time T a , at this time, the duration of the rear windshield and rearview mirror heating and defogging functions is relatively long. Although it has not reached the default time T a, most of the rain, fog, ice and frost on the rear windshield and rearview mirror have been removed, which may not have a great impact on safe driving. At this time, the issue of electrical balance needs to be considered. Since there is no problem with safety hazards, the heating and defogging functions of the rear windshield and rearview mirror can be suspended. This suspension of activation does not completely turn off the heating and defogging functions of the rear windshield and rearview mirror. It just means that the heating wires on the rear windshield and rearview mirror are no longer powered and heated. Further judgment needs to be made based on subsequent situations, and there may be cases of reactivation or deactivation.

[0060] In a further embodiment of the present application, this embodiment further optimizes the above control module. Specifically, the control module further includes a pause time recording module, and the pause time recording module is used to record the duration of the suspension of activation as the pause time; the third instruction module is used to issue an instruction to reactivate the heating and defogging functions of the rear windshield and rearview mirror when the pause time is less than the second preset time and the unloading request is cancelled during the pause time, otherwise it issues an instruction to continue suspending the activation of the heating and defogging functions of the rear windshield and rearview mirror.

[0061] The pause time T2 refers to the duration of the suspension of activation of the heating and defogging functions of the rear windshield and rearview mirror, that is, the time from the start of the suspension of activation of the heating and defogging functions of the rear windshield and rearview mirror to the end of the suspension of activation of the heating and defogging functions of the rear windshield and rearview mirror. The second preset time T3 is a preset time set artificially, generally set to 60s - 120s. The second preset time T3 in this embodiment is 60s. It is set according to actual needs during actual application.

[0062] In this embodiment, if the pause time T2 < the second preset time T3, and at this time the vehicle control unit (VCU) continues to send an instruction to cancel power unloading to the control module through the CAN bus, it proves that the power consumption of the vehicle at this time meets the requirements, and there is no need to continue suspending the heating and defogging functions of the rear windshield and rearview mirror. In order to further improve driving safety, it is necessary to further heat and defog the rear windshield and rearview mirror. Therefore, it is necessary to reactivate the heating and defogging functions of the rear windshield and rearview mirror.

[0063] Of course, if the pause time T2 < the second preset time T3, and the vehicle control unit (VCU) continues to send an instruction for power unloading to the control module through the CAN bus, it proves that during this period, the power consumption of the vehicle is still too high, and the DCDC power still does not meet the requirements. It is still necessary to further maintain the suspension of activation of the heating and defogging functions of the rear windshield and rearview mirror.

[0064] In some preferred embodiments of the present application, this embodiment further optimizes the above control module. Specifically, the control module further includes a fourth instruction module, and the fourth instruction module is used to issue an instruction to turn off the activated rear windshield and rearview mirror heating and defogging functions when the pause time is equal to the second preset time and the unloading request persists during the pause time.

[0065] In this embodiment, if the pause time T2 = the second preset time T3, at this time, the vehicle control unit (VCU) continues to send an instruction for power unloading to the control module through the CAN bus, which proves that the power consumption of the vehicle is still not meeting the requirements during the pause activation period, and the rear windshield and rearview mirror heating and defogging functions still cannot be turned on. Otherwise, the power of the DCDC does not meet the requirements. Therefore, the rear windshield and rearview mirror heating and defogging functions can be directly turned off.

[0066] In some other embodiments of the present application, this embodiment continues to optimize the control module. Specifically, the control module of this embodiment further includes a fifth instruction module, and the fifth instruction module is used to turn off the activated rear windshield and rearview mirror heating and defogging functions when the activation time reaches the default time.

[0067] In this embodiment, the activation time T0 of this embodiment is the duration of the rear windshield and rearview mirror heating and defogging functions. After pressing the button for the rear windshield and rearview mirror heating and defogging functions, the control module directly calculates the duration of the rear windshield and rearview mirror heating and defogging functions regardless of how many times the activation is paused in the middle. If this activation time T0 reaches the default time T a , it is considered that the duration of the rear windshield and rearview mirror heating and defogging functions is sufficient to remove the rain, fog, ice, and frost on the rear windshield and rearview mirror. Therefore, the rear windshield and rearview mirror heating and defogging functions can be directly turned off at this time.

[0068] Specifically, as Figure 1 shown, the control method of the present application can be carried out according to the following steps:

[0069] Record the activation time of the rear windshield and rearview mirror heating and defogging switch;

[0070] Judge whether the current state meets the initial condition that the rear windshield and rearview mirror heating and defogging switch is pressed and the DCDC power is insufficient;

[0071] If the initial condition is met and an unloading request is received, compare the activation time T0 with the first preset time T1;

[0072] If the activation time T0 < the first preset time T1, continue to activate the rear windshield and rearview mirror heating and defogging functions. If the activation time T0 > the first preset time T1 and < the default time T a , then pause the activation of the rear windshield and rearview mirror heating and defogging functions;

[0073] If the activation is paused, record the pause time T2. If the pause time T2 < the second preset time T3 and the unloading request is cancelled during the pause time, the rear windshield and rearview mirror heating and defogging functions are reactivated after reactivation. If the pause time T2 = the second preset time T3, the rear windshield and rearview mirror heating and defogging functions after activation are turned off;

[0074] If the activation time T0 reaches the default time, the rear windshield and rearview mirror heating and defogging functions after activation are also turned off T a 。

[0075] An embodiment of the present invention also provides a non-transitory computer-readable storage medium.
