Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle lamp design, and in particular relates to a vehicle lamp defrosting and deicing control method, device, equipment and medium. Background Art

[0002] As people pay more and more attention to safety, vehicle lighting requirements are getting higher and higher. In winter when the temperature is low, the surface of the headlights will be covered with a layer of frost or ice, which seriously affects the vehicle lighting and has a great impact on safe driving. After being blocked or scattered by frost, the light cannot illuminate the front view as designed. At present, most vehicles defrost and de-ice the headlights by waiting for the headlights to be turned on, and then defrost and de-ice with fans, or do not configure fans and directly rely on the headlights to heat themselves for defrosting and de-icing.

[0003] These two methods take a long time to complete defrosting and defrosting. Basically, defrosting and defrosting will not start until the driver turns on the lights. At this time, the lighting required by the driver cannot be provided in time, affecting safe driving. Moreover, for many vehicles, the defrosting and defrosting fans start working as soon as the lights are turned on, without considering whether they are needed at the moment, thus causing energy waste and shortening the working life of the fans. Summary of the invention

[0004] The purpose of the present invention is to provide a method, device, equipment and medium for controlling defrosting and deicing of vehicle lights. By collecting the external ambient temperature, external light intensity and door lock status, the resistance wire and fan are controlled to perform defrosting and deicing according to different working conditions, thereby solving the technical problems in the prior art that the defrosting and deicing time of vehicle lights is long, affecting the safe driving of the vehicle, and the lack of targeted work under different working conditions, thus causing energy waste.

Before the vehicle is driven, by collecting the external ambient temperature, light intensity and door unlocking signal, it is predicted in advance whether the defrosting and deicing function needs to be turned on, providing the driver with full lighting escort, avoiding the situation where the driver needs the vehicle lamp to be illuminated, but the frost and ice on the vehicle lamp have not been completely removed.

[0048] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0050] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0051] In order to solve the technical problems in the prior art that the long defrosting and deicing time of the headlights affects the safe driving of the vehicle and the energy waste is caused by not combining targeted work with different working conditions, the present invention provides a headlight defrosting and deicing control method, which can realize defrosting and deicing when the headlights are not turned on. By collecting signals such as the external environment temperature, the external environment light intensity, and the door lock status, it is determined whether it is necessary to immediately turn on the defrosting and deicing, and the driver's needs are predicted in advance. Defrosting and deicing are turned on in advance. When the driver turns on the lights to drive the vehicle, the vehicle has completed defrosting and deicing, ensuring that the vehicle provides complete lighting throughout the driving process. In addition, considering that the driver needs the headlights for lighting during the day, when the driver turns on the lights during the day, the front combination headlight control module controls the heating resistor and the fan to work at full power to shorten the defrosting and deicing time as soon as possible. In addition, considering that the headlights themselves generate more heat after being turned on, when a certain thermal balance is reached, the heating resistor stops working to reduce energy consumption and make full use of the headlights' own heat for defrosting and deicing. Please refer to Figure 1 As shown, the vehicle lamp defrosting and deicing control method comprises the following steps:

[0052] S100: Obtain the current door lock status of the vehicle;

[0053] S200: When the vehicle door lock is in an unlocked state, obtaining the current ambient light intensity and ambient temperature of the vehicle;

[0054] S300: Determine the time period in which the vehicle is currently located according to the ambient light intensity;

[0055] S400: Determine the resistance wire heating power, the fan speed, the resistance wire working time and the fan working time according to the ambient temperature and the time period;

[0056] S500: Controlling the resistance wire and the fan to defrost and de-ice the headlights according to the heating power of the resistance wire, the speed of the fan, the working time of the resistance wire and the working time of the fan.

[0057] The steps of the above-mentioned vehicle lamp defrosting and deicing control method will be discussed in detail below.

[0058] In an exemplary embodiment of the present application, a vehicle light defrost and de-icing control system is composed of a vehicle lock, an ambient light sensor ALS (Ambient Light Sensor), an ambient temperature sensor ATS (Air Temperature Sensor), a light switch, a front combination headlight control module HCM (Headlamp Control Module), a heating resistor, a fan and LED matrix headlights.

[0059] First, step S100 is executed to obtain the current door lock state of the vehicle.

[0060] In an exemplary embodiment of the present application, when the vehicle is powered on, the vehicle locker obtains the current door lock state of the vehicle and sends an unlock signal to the front combination headlight control module HCM. It should be noted that in this embodiment, the vehicle power-on method includes but is not limited to unlocking with an electric key, opening the door, etc.

[0061] Next, step S200 is executed, that is, when the vehicle door lock is in the unlocked state, the current ambient light intensity and ambient temperature of the vehicle are obtained.

[0062] Specifically, the front combination headlight control module HCM receives the unlocking signal provided by the vehicle lock, and determines whether to turn on the defrosting and deicing function of the lights according to the unlocking signal. When the door lock is in the locked state, the defrosting and deicing function of the lights is turned off; when the door lock is in the unlocked state, the defrosting and deicing function of the lights is turned on, and the current ambient light intensity of the vehicle is obtained through the ambient light sensor ALS and the current ambient temperature of the vehicle is obtained through the ambient temperature sensor ATS, and the current ambient light intensity signal and ambient temperature signal of the vehicle are sent to the front combination headlight control module HCM for processing. It should be noted that, in the present embodiment, the setting positions of the ambient light intensity sensor ALS and the ambient temperature sensor ATS on the vehicle include but are not limited to setting them on the lights, doors, etc. In addition, the setting number of the ambient light intensity sensor ALS and the ambient temperature sensor ATS can be one or more.

[0063] Next, step S300 is executed, that is, the time period in which the vehicle is currently located is determined according to the ambient light intensity.

[0064] In an exemplary embodiment of the present application, determining the time period in which the vehicle is currently located according to the ambient light intensity further includes the following steps:

[0065] S301: Determine whether the ambient light intensity is higher than a preset ambient light intensity threshold;

[0066] S302: If yes, the vehicle is currently in daytime;

[0067] S303: If no, the vehicle is currently in the evening.

[0068] Specifically, the front combination headlight control module HCM receives the ambient light intensity signal sent by the ambient light intensity sensor ALS, and compares it according to a preset ambient light intensity threshold. When the current ambient light intensity of the vehicle is greater than the preset light intensity threshold, it is determined that the vehicle is currently in the daytime time period; when the current ambient light intensity of the vehicle is less than or equal to the preset light intensity threshold, it is determined that the vehicle is currently in the night time period. It should be noted that if there are multiple ambient light intensity sensors ALS, the ambient light intensity data collected by the multiple ambient light intensity sensors ALS are fused to obtain fused light intensity data, and the vehicle's current time period is determined based on the fused light intensity data and the preset ambient light intensity threshold.

[0069] Next, step S400 is executed, that is, the resistance wire heating power, the fan speed, the resistance wire working time and the fan working time are determined according to the ambient temperature and the time period.

[0070] Specifically, if the vehicle is currently in the evening and the ambient temperature is lower than the preset ambient temperature threshold, the resistance wire heating power, the fan speed, the resistance wire working time and the fan working time are calculated according to the vehicle's current ambient temperature. If the vehicle is currently in the daytime, the vehicle's current light switch state is obtained. When the vehicle's current lights are on and the ambient temperature is lower than the preset ambient temperature threshold, the resistance wire heating power and the fan speed are controlled to be the maximum value, and the resistance wire working time and the fan working time are calculated according to the vehicle's current ambient temperature, wherein the resistance wire working time is less than the fan working time.

[0071] Finally, step S500 is executed, that is, the resistance wire and the fan are controlled to defrost and de-ice the lamp according to the heating power of the resistance wire, the speed of the fan, the working time of the resistance wire and the working time of the fan.

[0072] The following will explain in detail the control logic of defrosting and deicing of car lights:

[0073] When the vehicle is powered on for the first time, the ambient light intensity sensor ALS detects the current ambient light intensity of the vehicle, thereby determining whether the vehicle is currently in daytime or nighttime. At the same time, the ambient temperature sensor ATS detects the current ambient temperature of the vehicle. If the detection result is that it is currently nighttime and the ambient temperature is lower than the preset ambient temperature threshold W0, the front combination headlight control module HCM receives the above signal, and after the vehicle interlock sends an unlock signal, the front combination headlight control module HCM immediately controls the heating resistor and the fan to work. Under this condition, the working logic of the fan and the heating resistor is as follows:

[0074] The front combination headlight control module HCM calculates the heating time t required for the current ambient temperature, the output power P corresponding to the heating resistor, and the fan speed n according to the ambient temperature detected by the ambient temperature sensor ATS and the preset logic algorithm, and controls the heating resistor and the fan working duration t according to the above calculated parameters.

[0075] It should be noted that, under this working condition, the time t required for heating the current external environment temperature, that is, the defrosting and defrosting time of the heating resistor and the fan, is equal to the working time of the heating resistor and the fan.

[0076] The relationship between the current external environment temperature, the resistance wire, and the fan working time is shown in the following formula. For the relationship curve, please refer to Figure 2 As shown:

[0077]

[0078] Among them, k 1 , k 2 , k 3 is the correction factor, a 1 is the exponential base, and a 1 >1, t is the working time of the resistance wire and the fan, w is the ambient temperature, and w<0.

[0079] See also Figure 2 As shown, when the ambient temperature is W1, the heating resistor and the fan work for t1; when the ambient temperature is W4, the heating resistor and the fan work for t4. It is worth noting that the X-axis direction is the direction of decreasing ambient temperature.

[0080] The relationship between the current ambient temperature and the resistance wire heating power P is shown in the following formula. For the relationship curve, please refer to Figure 3 shown.

[0081]

[0082] Among them, k 4 , k 5 , k 6 is the correction factor, a 2 is the logarithm base, and a 2 >1, P is the heating power of the resistance wire, w is the ambient temperature, and w<0.

[0083] See also Figure 3 As shown, when the external environment temperature is lower than W0, the resistance wire starts to heat up. For example, when the external environment temperature is W1, the power of the heating resistance wire is P1; when the external environment temperature is W3, the power of the heating resistance wire is P3.

[0084] The relationship between the current ambient temperature and the fan speed n is shown in the following formula. For the relationship curve, please refer to Figure 4 shown.

[0085]

[0086] Among them, k 7 , k 8 , k 9 is the correction factor, a 3 is the logarithm base, and a 3 >1, n is the fan speed, w is the ambient temperature, and w<0.

[0087] See also Figure 4 As shown, when the external environment temperature is lower than W0, the fan starts to work. For example, when the external environment temperature is W1, the fan speed is n1, and when the external environment temperature is W3, the fan speed is n3.

[0088] Among them, the correction coefficient k 1 , k 2 , k 3 , k 4 , k 5 , k 6 , k 7 , k 8 , k 9 All of them are calculated through calibration and function fitting, and finally the above correction coefficients are determined within the allowed time (90% of the time from unlocking to driving the vehicle) to ensure that defrosting and deicing are completed, with the goal of minimizing the energy consumption of the resistance wire heating and the fan and maximizing the working life. It should be noted that when the vehicle is in an extremely low temperature environment (for example, below minus 50°C), the working time of the headlight defrosting and deicing will exceed the allowed time (even if the heating resistance wire and the fan are running at full power at this time). Of course, based on different vehicles, due to differences in headlight structure, shape and other differences, the above correction coefficients are also different.

[0089] If the ambient light sensor ALS detects that the current vehicle time period is daytime and the ambient temperature sensor ATS detects that the current ambient temperature is lower than the preset ambient temperature threshold W0, and the user turns on the headlights, the front combination headlight control module HCM immediately controls the heating resistor and the fan to work. Under this condition, the working logic of the heating resistor and the fan is as follows:

[0090] The heating resistor and the fan operate at maximum power for a first preset time t a After that, the heating resistor stops working, and the fan still runs at full power until the second preset time t b After that, the fan also stops working. The time t a ,t bis not a constant, they are logarithmically related to the ambient temperature, and t a <t b .

[0091] For details, please refer to Figure 5 As shown in the figure, the working time of the heating resistor is shorter than that of the fan. This is mainly because after the headlight is turned on, the headlight itself is also generating heat. When the headlight itself reaches thermal equilibrium, the heating resistor can stop working and use the heat automatically generated by the headlight and the fan to achieve the purpose of defrosting and deicing, thus fully saving energy. For example, when the external environment temperature is W1, the corresponding working time of the heating resistor is t a1 , the fan working time is t b1 , under the current external environment temperature, the heating resistance wire working time reaches t a1 When the headlight stops working, the heat generated by the headlight itself can meet the requirements of defrosting and deicing. At the same time, the fan still needs to work (t b1 -t a1 )time.

[0092] In summary, the present invention provides a vehicle lamp defrosting and deicing control method, by obtaining the current door lock state of the vehicle, when the door lock is in the unlocked state, obtaining the current ambient light intensity and ambient temperature of the vehicle, determining the current time period of the vehicle according to the ambient light intensity, determining the resistance wire heating power, fan speed, resistance wire working time and fan working time according to the ambient temperature and the time period, and controlling the resistance wire and fan to defrost and deicer the vehicle lamp according to the resistance wire heating power, fan speed, resistance wire working time and fan working time. The vehicle lamp defrosting and deicing control method, by collecting the external environment temperature, light intensity and door unlocking signal, predicts in advance whether the defrosting and deicing function needs to be turned on, provides the driver with full lighting escort, and avoids the driver needing the vehicle lamp lighting, but the frost and ice on the vehicle lamp have not been completely removed. Through the calibration and calculation of various working conditions, the curve relationship between the external environment temperature and the defrosting and deicing working time, the resistance wire heating power and the fan speed is summarized, so as to ensure that energy is saved as much as possible and the working life of the resistance wire and the fan is guaranteed under the premise of achieving a relatively satisfactory defrosting and deicing effect. In addition, for working conditions where lights need to be turned on during the day, another curve function relationship between the external ambient temperature and the working time of the heating resistor and the fan is proposed. On the premise of ensuring defrosting and deicing as soon as possible, the heat generated by the lamp itself is fully utilized based on the relationship between the heat generation and heat dissipation of the lamp itself, which not only saves unnecessary energy of the heating resistor, but also increases the working life of the heating resistor.
