Example 1

FIG. 1 is a first flow chart of a method for controlling an anti-glare rearview mirror according to an embodiment of the present application. Exemplarily, the anti-glare rearview mirror control method includes:

Step S110, when it is night time and the current temperature is lower than the preset minimum temperature, it is detected whether the anti-glare pre-starting condition is satisfied.

In this embodiment, the anti-glare rearview mirror mainly includes a lens with an electrochromic structure, a heating element, a temperature sensor, a front light intensity sensor facing the front of the vehicle, and a rear light intensity sensor facing the rear of the vehicle. Among them, the electrochromic structure is used to realize the anti-glare function of the rearview mirror, the heating element is used to heat the lens of the rearview mirror, and the front and rear light intensity sensors are used to obtain the light intensity in the corresponding direction; among them, it is judged whether the current vehicle is In the night time, you can set the ambient light sensor separately, or use the existing front light sensor to detect the ambient light intensity. For example, when the ambient light intensity is detected to be lower than a certain value, it can be considered that the environment where the vehicle is located It is already in the night time period; or, it can also be judged whether the current vehicle is in the night time through local time, networking, and the user directly selecting the night time period. The temperature sensor can have one or more temperature sensors used to collect the temperature of the rearview mirror and the temperature of the external environment. Wherein, the acquisition method of the external environment temperature may be collected by a separate temperature sensor, or may be local temperature obtained by network communication or the like. In addition, in some cases, such as when the vehicle has not been heated for a long time or when the vehicle is just started, the ambient temperature can also be taken as the temperature of the rearview mirror when the vehicle is started, or it can be obtained by measuring the curve of the temperature of the rearview mirror and taking The average number of several minimum temperature points in the curve is used as the ambient temperature, etc., which is not limited here.

When the vehicle is in a cold and low temperature night, if the temperature is too low, the anti-glare rearview mirror may change color slowly at this time, and it is difficult to realize the anti-glare effect in time, which may cause driving risks to the driver. Therefore, heating is required. However, when heating, this embodiment needs to detect the anti-glare pre-starting condition under the premise of satisfying the low temperature, and then start the pre-heating of the rearview mirror, so as to achieve the purpose of energy saving.

Wherein, the current temperature may be the collected temperature of the rearview mirror, or may be the temperature of the external environment. For example, the above-mentioned preset minimum temperature may be about -10°C, which may also be adjusted adaptively according to actual needs.

The aforementioned anti-glare pre-starting condition refers to the starting condition of the pre-heating operation before starting the anti-glare. In this embodiment, the degree of difference in light intensity between the front and rear of the vehicle can be used to determine whether glare is about to occur. It can be understood that when there is a car approaching behind the car, if the rear car turns on the headlights, the rear light intensity sensor of the vehicle will detect that the rear light intensity in the direction of the rear of the vehicle is getting stronger and stronger, that is, the front and rear light intensity of the vehicle The difference will gradually increase. For this reason, two light intensity difference values of different sizes can be set here, wherein the first preset light intensity difference value is smaller than the second preset light intensity difference value, and when the first preset light intensity difference value is reached, it indicates that a short time In the event of glare, the mirrors are heated in advance to ensure that they can change color quickly if required. And when the second preset light intensity difference value is reached, it means that the condition of glare is met, and at this time, a discoloration operation is required to prevent glare.

In another case, if the vehicle coming from the side and rear is in the blind spot, it is likely that the vehicle behind the side will leave the blind spot and enter the field of view of the rearview mirror due to the acceleration of the vehicle or the deceleration or lane change of the vehicle behind the side. The glare of the rearview mirror of the car is rapidly caused, and if in this case, the glare is still predicted based on the above-mentioned difference in light intensity and then preheated, the antiglare rearview mirror may not be preheated in time. For this, this embodiment The blind spot detector (BSD) can also be used to detect whether there is a vehicle in the blind spot. When there is a vehicle in the blind spot, the blind spot detector can send a signal that there is a vehicle in the blind spot. At this time, the rearview mirror will be heated in advance to ensure that the rearview mirror can be used when needed rapid color change.

In one embodiment, if any one of the following situations is detected, it can be determined that the above-mentioned anti-glare pre-starting condition is met, which may include but not limited to: when it is detected that the front light intensity in the direction of the vehicle is When the light intensity difference value between the rear light intensities in the tail direction is greater than or equal to the first preset light intensity difference value; or, when receiving a signal that there is a vehicle in the blind area of the field of vision, etc.

For example, the above light intensity difference value can be the light intensity ratio between the front light intensity and the rear light intensity in the direction of the front of the vehicle. Of course, it can also be other parameters that can be used to indicate the difference between the front and rear light intensities, such as The difference between the light intensity and the back light intensity, or the logarithmic ratio of the front light intensity and the back light intensity, etc., are not limited here. It can be understood that the preset light intensity difference value in this embodiment can be selected according to the actual light intensity difference value. In addition, in order to improve the judgment accuracy, the light intensity difference value in this embodiment can compare multiple data collected continuously, and determine the final light intensity difference value according to the results of multiple comparisons, which can reduce the probability of misjudgment.

In this embodiment, under the premise of low temperature at night, it is judged whether glare is about to occur through the difference in light intensity between front and rear, vehicle detection in blind spots, etc., and when it is judged that glare is about to occur, the rearview mirror is preheated in advance so that it can quickly change color when needed .

Step S120, when the anti-glare pre-starting condition is satisfied, start the heating operation of the rearview mirror until the heating reaches the target temperature under the current environment.

Wherein, the above-mentioned target temperature refers to a temperature point that is conducive to the subsequent rapid discoloration of the rearview mirror. It is worth noting that the target temperature in this embodiment may not be a constant value, and may also be related to the ambient temperature at that time, specifically, it may be determined in real time according to a preset relationship between the target temperature and the ambient temperature.

For the above target temperature, all possible ambient temperature values are divided into multiple temperature ranges. When the ambient temperature is in different temperature ranges, the target temperature is determined in different ways. For example, in one embodiment, it can be divided into three intervals, namely the first to third preset temperature intervals, wherein the first preset temperature interval, the second preset temperature interval and the third preset temperature interval The temperature increases sequentially, that is, the temperature in the second preset temperature range is not lower than the temperature in the first preset temperature range, and the temperature in the third preset temperature range is not lower than the temperature in the second preset temperature range . For example, in one embodiment, the maximum value of the second preset temperature range may be set as the aforementioned preset minimum temperature or the like. It can be understood that the first preset temperature range is a color-changing temperature range, the second preset temperature range is a transition temperature range, and the third preset temperature range is a suitable color-changing temperature range. Preheat the rearview mirror. In addition, it can also be divided into two temperature ranges, four temperature ranges, etc., which can be adaptively adjusted according to actual needs.

Based on the above three interval divisions, exemplary, the preset relationship between the two temperatures can be described as:

When the ambient temperature is in the first preset temperature range, the target temperature is set as a first temperature value; when the ambient temperature is in the second preset temperature range, the target temperature and the ambient temperature satisfy a preset function. For example, taking the case where the first preset temperature range is less than -40°C, the second preset temperature range is -40°C to 0°C, and the third preset temperature range is greater than 0°C, in a preset In the relationship, as shown in FIG. 2a, the above-mentioned first temperature value can be set as a fixed value, which can be selected according to actual needs. Optionally, the value range can be -16°C to -20°C. At this time, the second preset temperature interval includes two sub-intervals, namely the first sub-interval [-40°C to -20°C) and the second sub-interval [-20°C to 0°C), correspondingly, as a piecewise function The preset function of has a different expression in each subinterval. Wherein, the target temperature in the first sub-interval can be set as a fixed value, and its value range can refer to the selection of the first temperature value in the first preset temperature interval, and the slope at this time is 0; in the second sub-interval, the target The temperature is linearly related to the ambient temperature with a slope of 1. At this time, in the third preset temperature range, because it is suitable for the discoloration temperature range, for example, the target temperature can be set as the ambient temperature, so that if the vehicle is currently in the current temperature range, the anti-glare rearview mirror will not be triggered in advance. Heating operation.

Optionally, it may also be set as the second preset relationship as shown in FIG. 2b, or the third preset relationship as shown in FIG. 2c. The difference between the above preset relationships mainly lies in that the division of the sub-intervals of the second preset temperature range is different, and correspondingly, the expressions of the preset functions are also different.

Specifically, in the second preset relationship, the second preset temperature interval is also divided into two sub-intervals, namely the first sub-interval [-40°C ~ -30°C) and the second sub-interval [-30°C ~ 0℃), wherein, in the sub-interval [-40℃～-30℃), the target temperature can be set as a fixed value, such as -20℃, etc., and in the sub-interval [-30℃～0℃), the target temperature It is positively correlated with the ambient temperature and the slope of the tangent line is not greater than 1. In the third preset relationship, the second preset temperature range includes only one range [-20° C.˜0° C.), and the preset function at this time is a linear function with a slope less than 1 and not passing through the origin.

It can be understood that the relationship curves between the above several target temperatures and the ambient temperature are only some examples, and are not intended to be the only limitation. In this embodiment, energy can be saved by setting different heating strategies in different ambient temperature zones. For example, when it is in the temperature range suitable for discoloration, the target temperature is set to the ambient temperature, so that no heating is required; when it is in the temperature range where discoloration cannot be achieved, the target temperature can be set as the transition temperature point, so as to heat more to ensure performance; When it is in the transition temperature range, the target temperature can be set to increase with the increase of the ambient temperature. Compared with the temperature range where the color cannot be changed, it can be heated less.

Exemplarily, when any one of the above-mentioned anti-glare pre-starting conditions is detected, it indicates that rearview mirror glare may occur subsequently. Therefore, this embodiment will start the preheating operation for the rearview mirror until It is heated to the target temperature corresponding to the current ambient temperature to ensure that the rearview mirror can quickly respond to the color change when the anti-glare needs to be activated. Further optionally, after heating to the target temperature, the heating can be stopped according to actual needs, or maintained at around the target temperature (ie heat preservation operation), etc.

Optionally, the heating element of the rearview mirror in this embodiment can be provided with different heating gears, including the first power gear and the second power gear, and the heating power of the second power gear will be higher than The heating power of the first power gear. For example, when the anti-glare pre-start condition is met or the anti-glare function is turned on, the second power gear can be selected to perform a strong heating operation on the rearview mirror; The power level heats the mirrors.

Alternatively, only one heating power gear can be set, specifically, when the rearview mirror needs to be heated, the rearview mirror can be heated, and when the target temperature is reached or the temperature is maintained, the heating can be started intermittently , so that the temperature is always kept near the current temperature or the target temperature. It can be understood that for heating elements with different heating gears, the rearview mirror can be kept at the current temperature or near the target temperature by starting the heating intermittently.

Further, as shown in Figure 3, the anti-glare rearview mirror control method also includes:

Step S130, during the heating operation, continuously acquire the light intensity difference value between the front light intensity in the direction of the front of the vehicle and the rear light intensity in the direction of the rear of the vehicle.

Step S140, detecting whether the real-time updated light intensity difference value is greater than or equal to a second preset light intensity difference value. It can be understood that the second preset light intensity difference value is greater than the above-mentioned first preset light intensity difference value.

Exemplarily, during the heating process, the rearview mirror will continuously collect the light intensity difference value, and immediately execute the anti-glare function when it detects that the updated light intensity difference value is greater than or equal to the second preset light intensity difference value.

Step S150, if it is greater than or equal to the second preset light intensity difference value, start the color changing operation.

Exemplarily, the electrochromic structure in the rearview mirror can be pressurized to adjust the light transmittance of the electrochromic structure, and by dimming the rearview mirror, the reflection of the rearview mirror can be reduced when the car coming from behind Light intensity, to avoid too dazzling reflected light, to ensure driving safety, etc.

For example, in one situation, when the temperature is low at night, the vehicle coming from behind gradually drives towards the vehicle and keeps following the vehicle, causing the front-to-rear light intensity ratio of the vehicle to gradually increase, and then maintain a higher light intensity ratio. Intensity ratio, when the rearview mirror detects that the front and rear light intensity ratio is higher than the first preset light intensity ratio, it will start the preheating of the rearview mirror until it reaches the target temperature and maintain the temperature; then, when the front and rear light intensity ratio increases When the second preset light intensity ratio corresponding to the color change of the anti-glare rearview mirror is triggered, the rearview mirror is controlled to start to change color; when the color change is completed, the rearview mirror already has the anti-glare effect, and the vehicle behind has been driving with the car. Since the transmittance of the anti-glare rearview mirror is already lower than the preset transmittance, the vehicle does not need to continue heating at this time, so the heating power can be reduced, or intermittently heated, or directly stopped.

As an optional solution, if it is detected that the rearview mirror has completed the color changing operation, that is, when the current transmittance of the rearview mirror is lower than the preset transmittance, considering that the subsequent rearview mirror may need to further adjust the transmittance rate to achieve fading operation, etc., in order to quickly respond to subsequent adjustment operations, after discoloration, maintain the rearview mirror at the current heating temperature.

For the above step S140, optionally, if it is detected that the continuously updated light intensity difference value does not reach the second preset light intensity difference value, but is still greater than the first preset light intensity difference value, the detection can be continued, and heating is maintained. When the current temperature or the target temperature is near, no other operations can be performed at this time. Further optionally, if it is detected that the continuously updated light intensity difference value is smaller than the first preset light intensity difference value again, it indicates that no glare will occur in a short period of time, and step S160 is executed at this time.

Step S160, if it is less than the first preset light intensity difference value, stop the heating operation of the rearview mirror or maintain the current heating temperature.

Exemplarily, if it is detected that glare will not occur for a short period of time, the heating operation can be stopped directly at this time, and the temperature reached during the current heating can also be maintained. For example, the current heating temperature can be the temperature before the target temperature is reached. The temperature may be a temperature near the attained target temperature or the like.

Further, as shown in Figure 4, the anti-glare rearview mirror control method also includes:

Step S170, during the heating operation, continuously detect whether there is a vehicle in the blind area of vision.

Step S180, when it is detected that there is no vehicle in the blind spot, stop the current heating operation or maintain the current heating temperature.

Exemplarily, when it is detected that there is no vehicle in the blind spot, it indicates that there is no vehicle in the blind spot that may soon enter the sight area of the rearview mirror, and glare will not occur temporarily. Therefore, the heating operation may be stopped or maintained at the current heating temperature or the like.

As another optional solution, the heating function for anti-glare in this embodiment can also be combined with weather conditions such as rain, snow, and freezing rain; for example, when it is raining, the anti-glare rear view The heating of the mirror makes the rearview mirror at the temperature of the rain removal mode, so that the rainwater evaporates quickly, avoiding the problem of poor vision of the rearview mirror caused by raindrops attached to the mirror surface. When it snows, snowflakes are easy to adhere to the rearview mirror, and it is easy to form ice on the mirror in freezing rain. These weathers will affect the clarity of the rearview mirror. Therefore, in the above situations, you can use After the rearview mirror is heated, it is maintained at a temperature that is anti-snow and anti-freeze, so as to realize the effects of anti-glare, anti-rain/snow/freezing rain, etc. at the same time.

The anti-glare rearview mirror control method of this embodiment hardly needs to change the existing structure and materials of the rearview mirror. In the case of low temperature at night, it can be judged whether it is Glare is about to occur, and when it is judged that glare is about to occur, preheat the rearview mirror in advance, on the one hand, it can quickly change color when needed, on the other hand, compared with the traditional solution of constant heating, it can save energy, and because the rearview mirror It does not need to be in a high-temperature heating state for a long time, which prolongs the service life of the anti-glare rearview mirror.
