Vehicle fog lights, typically comprising a front fog light and a rear fog light, are mounted at the front and rear of the vehicle, respectively, for illuminating the road during driving in rainy and foggy weather. The front fog lamp is slightly lower than the front lamp, and generally emits bright yellow light, because the visibility of the fog lamp is low, the sight of a driver is limited, and the penetration of the yellow light is strong, so that the visibility of the driver can be improved. The rear fog lamp emits strong red light, and is mainly used for enabling a driver in a rear vehicle to find a front vehicle in time in environments with low visibility such as fog, snow, rain or dust diffusion.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for a vehicle fog lamp according to an embodiment of the present invention.
The control method of the vehicle fog lamp provided by the embodiment of the invention comprises the following steps S11 to S13:
step S11, when the whole vehicle is electrified and the light gear is in the automatic gear, the rainfall and air particle concentration acquisition operation is executed: acquiring current rainfall and current air particle concentration; wherein the current rainfall is acquired by a rainfall sensor mounted on the vehicle, and the current air particle concentration is acquired by an air particle concentration sensor mounted on the vehicle.
Step S12, when detecting that the current rainfall meets a rainfall threshold condition and detecting that the current air particle concentration meets an air particle concentration threshold condition, acquiring current weather information through a network; and the current weather information comprises a current rainfall network value and a current visibility network value.
And S13, controlling the vehicle fog lamp to be turned on when the current weather information meets the fog lamp turning-on condition.
The control method of the vehicle fog lamp provided by the embodiment of the invention comprises the steps of acquiring the current rainfall acquired by a rainfall sensor and the current particle concentration acquired by an air particle concentration sensor when the whole vehicle is detected to be powered on and the light gear is in an automatic gear, further acquiring the current weather information through a network when the current rainfall is detected to meet the rainfall threshold condition and the current air particle concentration is detected to meet the air particle concentration threshold condition, and controlling the vehicle fog lamp to be turned on when the current weather information meets the fog lamp turning-on condition.
In the embodiment of the invention, the current driving environment can be preliminarily judged by acquiring the current rainfall acquired by the rainfall sensor and the air particle concentration acquired by the air particle concentration sensor, and then the current weather information is acquired through the network so as to further judge whether the fog lamp needs to be started. In the specific implementation, when it is detected that the current rainfall meets the rainfall threshold condition and the current air particle concentration meets the air particle concentration threshold condition, it may be considered that the current rainfall is large and the current air particle concentration is high, and since the rainy day and the haze do not occur at the same time in actual life, the reason for the occurrence may be that a rain sensor or an air particle concentration sensor fails, at this time, in order to accurately determine the current weather condition, in the embodiment of the present invention, when it is detected that the current rainfall meets the rainfall threshold condition and the current air particle concentration meets the air particle concentration threshold condition, it is necessary to further obtain weather forecast information of a network, and determine whether the current weather information meets a fog lamp turn-on condition according to a current rainfall network value and a current visibility network value in the weather forecast, and when it is detected that the current weather information meets the fog lamp turn-on condition, so that the fog lamp can be turned on accurately, and the safety of a driver can be further ensured.
In an embodiment of the invention, the execution subject of the control method of the vehicle fog lamp can be a vehicle Body Controller (BCM), and the vehicle body controller is respectively connected with the rain sensor and the air particle concentration sensor, so that the vehicle body controller can communicate with the rain sensor and the air particle concentration sensor and receive signals output by the rain sensor and the air particle concentration sensor. The rainfall sensor is used for detecting the grade of the current rainfall, and the air particle concentration sensor is used for detecting the grade of the current air particle concentration. The rainfall sensor can be an optical rainfall sensor or a capacitance rainfall sensor. The present invention is not particularly limited thereto.
In an embodiment of the present invention, the signal output by the rainfall sensor is a signal indicating a rainfall level, for example, when the current rainfall collected by the rainfall sensor is less than 10, the rainfall sensor outputs "a"; when the current rainfall collected by the rainfall sensor is 10-20, the rainfall sensor outputs B; when the current rainfall collected by the rainfall sensor is more than 20, the rainfall sensor outputs 'C'; similarly, the signal output by the air particle concentration sensor is also a signal indicating the level of the air particle concentration, for example, when the current air particle concentration collected by the air particle concentration sensor is less than 115, the air particle concentration sensor outputs "a", and when the current air particle concentration collected by the air particle concentration sensor is 115 to 125, the air particle concentration sensor outputs "B"; when the current air particle concentration collected by the air particle concentration sensor is greater than 125, the air particle concentration sensor outputs "C". When the output of the rainfall sensor is B or C, the current rainfall can be considered to belong to a high rainfall level; when the air particle sensor output is "B" or "C", the current air particle concentration may be considered to be in the high concentration level.
In the embodiment of the present invention, the current weather information includes the current rainfall network value and the current visibility network value, and the current rainfall network value and the current visibility network value are weather forecast data acquired through a network. In specific implementation, the specific position of the current vehicle may be obtained first, and then the current weather information of the location where the specific position of the current vehicle is located may be obtained through the network. For example, after the specific position of the current vehicle is obtained, networking through TBOX and calling weather forecast information in weather application software, so as to obtain the current weather information; or after the specific position of the current vehicle is obtained, the weather forecast information of the weather application software is called through the mobile phone WIFI network to obtain the current weather information.
Based on the solution provided by the foregoing embodiment, in an optional implementation manner, that the current rainfall satisfies the rainfall threshold condition means that the current rainfall level is a high rainfall level; wherein the level of the current rainfall is determined according to the magnitude of the current rainfall. For example, when it is detected that the current rainfall is "B" or "C", the level of the current rainfall is considered as the high rainfall level.
Based on the solutions provided in the above examples, in an alternative implementation, that the current air particle concentration satisfies the air particle concentration threshold condition means that the level of the current air particle concentration is a high concentration level; wherein the level of the current air particle concentration is determined according to the magnitude of the current air particle concentration. For example, when the current air particle concentration is detected as "B" or "C", the current air particle concentration may be considered to belong to the high concentration class.
In an optional implementation manner, the fact that the current weather information meets the fog lamp turning-on condition means that the current rainfall network value is greater than or equal to a preset rainfall threshold, or the current visibility network value is greater than or equal to a preset visibility threshold.
In the embodiment of the invention, the current rainfall network value and the current visibility network value are both in numerical representation forms, and the preset rainfall threshold value is compared with the current rainfall network value to judge whether the magnitude of the current rainfall is greater than or equal to the preset rainfall threshold value, if the current rainfall network value is greater than or equal to the preset rainfall threshold value, the current rainfall can be considered to be greater, the driving sight of a driver is limited, and therefore, a fog light needs to be turned on. Similarly, whether the current weather information meets the fog lamp starting condition or not can be judged by carrying out similar judgment logics on the current visibility network value. In a specific implementation, the obtained current rainfall network value may be preferentially compared with a preset rainfall threshold, and when it is detected that the current rainfall network value is greater than or equal to the preset rainfall threshold, it may be determined that the current weather information satisfies a fog lamp turning-on condition, without further comparing the current visibility network value with the preset visibility threshold. Of course, the current visibility network value may be compared with a preset visibility threshold value, and when it is detected that the current visibility network value is greater than or equal to the preset visibility threshold value, it is determined that the current weather information satisfies the fog lamp turning-on condition, without further comparing the current rainfall network value with the preset rainfall threshold value.
In another optional embodiment, that the current weather information satisfies the fog light turn-on condition means that the current weather information satisfies the following condition:
k 1 r+k 2 v≥b
wherein b is a preset threshold value, k 1 Is the rain proportional coefficient, k 2 And the ratio coefficient is the air particle concentration ratio coefficient, r is the current rainfall network value, and v is the current visibility network value.
In the embodiment of the invention, the fog lamp starting condition can be judged by constructing a combined function of the current rainfall network value and the current visibility network value and according to the result of the combined function of the current rainfall network value and the current visibility network value.
In an optional embodiment, after the step S12 "when it is detected that the current rainfall satisfies the rainfall threshold condition and it is detected that the current air particle concentration satisfies the air particle concentration threshold condition, obtaining the current weather information through the network" further includes:
and when the current weather information does not meet the fog lamp starting condition, returning to the operation of acquiring the rainfall and the air particle concentration.
In the embodiment of the invention, when it is detected that the current rainfall meets the rainfall threshold condition and the current air particle concentration meets the air particle concentration threshold condition, the level of the current rainfall is considered to be higher, and the level of the current air particle concentration is also higher. In order to avoid the misjudgment of the control logic for automatically turning on the fog lamp due to the failure of the rainfall sensor or the air particle concentration sensor, the control logic for automatically turning on the fog lamp needs to be further judged by combining the current weather information in the network weather forecast. Specifically, when it is detected that the current weather information does not satisfy the fog lamp turning-on condition, that is, the current driving environment is considered to be poor, the driving sight of the driver is limited, and therefore the fog lamp of the vehicle is controlled to be turned on.
In an alternative embodiment, in step S11", when it is detected that the entire vehicle is powered on and the light gear is in the automatic gear, the rainfall and air particle concentration obtaining operation is performed: after acquiring the current rainfall and the current air particle concentration ", the method further comprises the following steps:
when the current rainfall is detected to meet the rainfall threshold condition and the current air particle concentration is detected not to meet the air particle concentration threshold condition, controlling the vehicle fog lamp to be turned on;
and controlling the vehicle fog light to be turned on when the current rainfall is detected not to meet the rainfall threshold condition and the current air particle concentration is detected to meet the air particle concentration threshold condition.
In the embodiment of the invention, when it is detected that the current rainfall meets the rainfall threshold condition or the current particle concentration meets the air particle concentration threshold condition, the current rainfall is considered to be larger, or the current air particle concentration is higher, which already influences the driving sight of the driver, so that the operation of controlling the fog lamp of the vehicle to be turned on is executed.
In an alternative embodiment, in step S11", when it is detected that the entire vehicle is powered on and the light gear is in the automatic gear, the rainfall and air particle concentration obtaining operation is performed: after obtaining the current rainfall and the current air particle concentration ", the method further comprises the following steps:
when detecting that the current rainfall does not meet the rainfall threshold condition and detecting that the current air particle concentration does not meet the air particle concentration threshold condition, acquiring current weather information through a network;
when the current weather information does not meet the fog lamp starting condition, returning to the operation of acquiring the rainfall and the air particle concentration;
and when the current weather information meets the fog lamp starting condition, controlling the vehicle fog lamp to be started.
In the embodiment of the present invention, when it is detected that the current rainfall does not satisfy the rainfall threshold condition and the current air particle concentration does not satisfy the air particle concentration threshold condition, it may be determined that the current rainfall level is low and the current air particle concentration is low, and at this time, in order to more accurately determine the current driving environment, it is necessary to further obtain the current weather information through a network, and control the vehicle fog lamp to be turned on or off according to the current weather information.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of a control method for a vehicle fog lamp provided by the invention. In this embodiment, the control method of the vehicle fog lamp includes steps S1 to S4:
step S1, when the whole vehicle is electrified and the light gear is in the automatic gear, executing step S2;

if the grade of the current rainfall is smaller than B, judging whether the grade of the current air particle concentration is larger than or equal to B, and if the grade of the current air particle concentration is larger than or equal to B, executing a step S4; if the level of the current air particle concentration is smaller than B, further judging whether the current weather information meets the fog lamp starting condition, and if the current weather information meets the fog lamp starting condition, executing the step S4; if the current weather information does not meet the fog lamp starting condition, returning to the step S2;
