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 any inventive step, are within the scope of the present invention.

An embodiment of the present invention provides a driving visual field enhancement method in a rainy day, which is a flowchart of a preferred embodiment of the driving visual field enhancement method in a rainy day, shown in fig. 1, and includes steps S11 to S14:

step S11, when the first sensor detects rain, the second sensor detects the light brightness of the external environment of the vehicle in real time;

step S12, judging the light change of the external environment according to the currently detected first light brightness and the last detected second light brightness;

step S13, when the light change meets the preset change condition, judging whether the working mode of the wiper blade of the vehicle is an intermittent wiping mode;

and step S14, if the working mode is the intermittent wiping mode, controlling the wiper blade to execute the wiper action.

Specifically, when rain is detected by a first sensor (such as a rainfall sensor), the light brightness of the external environment of the vehicle is detected in real time by a second sensor (such as a light sensor) and recorded; judging the light change condition of the external environment of the vehicle according to the currently detected first light brightness and the recorded last detected second light brightness; when the light change of the external environment of the vehicle meets the preset change condition, the wiper system of the vehicle is in a normal working state due to the fact that rain is detected by the first sensor, and whether the working mode of a wiper blade in the wiper system is an intermittent wiping mode is further judged; if the working mode of the wiper blade is judged to be the intermittent wiping mode, the wiper blade is controlled to execute the wiper action once through the wiper motor so as to eliminate raindrops on the glass of the vehicle.

It can be understood that if the working mode of the wiper blade is not determined to be the intermittent wiping mode, the working mode of the wiper blade can be adjusted to be the intermittent wiping mode, and then the wiper blade is controlled by the wiper motor to execute the wiper motion once.

According to the driving visual field enhancing method in the rainy period, when the rainy period is detected and the light change of the external environment of the vehicle meets the preset change condition, the wiper blade in the intermittent wiping mode is controlled to execute the wiper action once, so that raindrops on the glass of the vehicle can be eliminated, the interference of the raindrops on the driving visual field of the vehicle can be reduced when the ambient light changes obviously, the driving safety is improved, and the driving experience of a user is improved.

In another preferred embodiment, the variation condition is specifically:

the brightness difference value of the first light brightness and the second light brightness is out of a preset brightness threshold range; wherein the first light brightness is less than the second light brightness.

Specifically, with reference to the foregoing embodiment, the preset change condition is that the detected luminance difference between the first light luminance and the second light luminance is outside the preset luminance threshold range, which indicates that the ambient light is obviously changed; and the first light brightness is less than the second light brightness, which indicates that the change condition of the light brightness of the external environment of the vehicle is from bright to dark (for example, the vehicle enters a tunnel, a garage, a bridge and other light and dark environments from a bright environment), therefore, when the light change of the external environment of the vehicle is judged to meet the change condition, and the working mode of the wiper blade is further judged to be an intermittent wiping mode, the wiper blade is controlled to execute the wiper action once, raindrops on the glass of the vehicle can be eliminated, and the interference of the raindrops on the driving visual field of the vehicle can be reduced when the ambient light is from bright to dark.

It should be noted that, when it is determined that the vehicle enters the bright environment from the dark environment, since the requirement of human eyes for the sight line is weakened, whether to control the wiper blade to perform the wiper action once can be selected according to the actual requirement.

In a further preferred embodiment, the method determines whether the operating mode is an intermittent scraping mode by:

detecting a motion state of the wiper blade by a wiper system of a vehicle;

and judging whether the working mode is an intermittent scraping mode or not according to the motion state of the wiper blade.

Specifically, in combination with the above embodiment, since the wiper blade is in different operating modes, and the moving states of the wiper action are different, the operating mode of the wiper blade can be directly determined by the wiper system of the vehicle, that is, the moving state of the wiper blade is directly detected by the wiper system, so as to determine whether the operating mode of the wiper blade is the intermittent wiping mode according to the moving state of the wiper blade.

In a further preferred embodiment, the method determines whether the operating mode is an intermittent scraping mode by:

judging the rainfall level according to the rainfall detected by the first sensor;

and judging whether the working mode is an intermittent scraping mode or not according to the rainfall level.

Specifically, in combination with the above embodiment, when the working mode of the wiper blade is controlled by matching the real-time detected rainfall amount, the rainfall amount grade can be judged according to the rainfall amount detected by the first sensor, so as to judge whether the working mode of the wiper blade is the intermittent wiping mode according to the rainfall amount grade.

As an improvement of the above scheme, the working modes at least comprise an intermittent scraping mode, a low-speed continuous scraping mode and a high-speed continuous scraping mode; the rainfall levels comprise at least a first level, a second level and a third level; then, the determining whether the working mode is an intermittent scraping mode according to the rainfall level specifically includes:

and when the rainfall level is the first level, judging that the working mode is an intermittent scraping mode.

Specifically, in combination with the above embodiment, the working modes of the wiper blade at least include an intermittent wiping mode, a low-speed continuous wiping mode and a high-speed continuous wiping mode, the rain amount can be classified according to the rain amount, the classified rain amount grades at least include a first grade, a second grade and a third grade, and different rain amount grades correspond to different working modes, for example, the first grade corresponds to light rain, and the working mode of the wiper blade can be controlled to be the intermittent wiping mode by the wiper motor; the second level corresponds to medium rain, and the working mode of the wiper blade can be controlled to be a low-speed continuous wiping mode through the wiper motor; the third level corresponds to heavy rain or heavy rain, and the working mode of the wiper blade can be controlled to be a high-speed continuous wiping mode through the wiper motor, so that when the rainfall level detected by the first sensor is judged to be the first level, the working mode of the wiper blade can be judged to be an intermittent wiping mode, correspondingly, when the rainfall level detected by the first sensor is judged to be the second level or the third level, the working mode of the wiper blade can be judged to be a low-speed continuous wiping mode or a high-speed continuous wiping mode, namely, the working mode of the wiper blade is judged not to be the intermittent wiping mode.

It is understood that the operating mode of the wiper blade may further include a stop mode, the rain level may further include a fourth level, the fourth level corresponds to no rain, the operating mode of the wiper blade may be controlled to be the stop mode by the wiper motor, that is, the wiper blade stops, and when the rain level is determined to be the fourth level according to the magnitude of the rain detected by the first sensor, the operating mode of the wiper blade may be determined to be the stop mode, that is, not to be the intermittent wiping mode.

The embodiment of the present invention further provides a driving visual field enhancement device during raining, which can implement all the processes of the driving visual field enhancement method during raining described in any one of the above embodiments, and the functions and implemented technical effects of each module and unit in the device are respectively the same as those of the driving visual field enhancement method during raining described in the above embodiment, and are not described herein again.
