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 method for controlling an automatic wiper function, which is a flowchart of a preferred embodiment of the method for controlling an automatic wiper function according to the present invention, as shown in fig. 1, and the method includes steps S11 to S14:

step S11, when the vehicle is powered on, activating the wiper sensor;

step S12, when the rain sensor detects rain, judging whether the gear of the wiper switch is in AUTO gear;

step S13, if the gear of the wiper switch is not in AUTO gear, the gear of the wiper switch is adjusted to AUTO gear, and the working mode of the wiper blade is controlled according to the rainfall detected by the wiper sensor;

and step S14, if the gear of the wiper switch is in AUTO gear, controlling the working mode of the wiper blade according to the rainfall detected by the wiper sensor.

Specifically, when a vehicle is powered on, a wiper sensor is directly activated, whether the external environment of the vehicle rains or not is detected in real time through the wiper sensor, when the rain is detected, whether the gear of a wiper switch of the vehicle is in an AUTO gear or not is judged, if the gear of the wiper switch is not in the AUTO gear, the gear of the wiper switch is adjusted to the AUTO gear, and the working mode of a wiper blade is controlled through a wiper motor according to the rain quantity detected by the wiper sensor in real time; if the gear of the wiper switch is in AUTO gear, the working mode of the wiper blade is directly controlled by the wiper motor according to the rainfall detected by the wiper sensor in real time.

It should be noted that the gears of the wiper switch at least include five gears of OFF, AUTO, intermittent, low speed and high speed, when the gears are in automatic gear, the wiper action of the wiper blade matches the magnitude of the rainfall detected by the wiper sensor in real time, when the gears are in non-automatic gear (i.e. any gear other than automatic gear), the wiper action of the wiper blade is driven and controlled by the wiper motor according to the actual gear of the wiper switch, wherein the gears of the wiper switch can be manually controlled by the driver, and other feasible control methods can also be implemented, and the embodiment of the invention is not particularly limited.

According to the control method for the automatic wiper function, provided by the embodiment of the invention, the related functions of the wiper sensor are activated when a vehicle is powered on, and when the rain is detected in real time by the wiper sensor and the gear of the wiper switch is in the AUTO gear, the working mode of the wiper blade is adjusted according to the rain amount detected in real time by the wiper sensor, so that the wiper action of the wiper blade can be matched with the current rain amount in time, the response time of the automatic wiper function can be saved, and the user experience is improved.

In another preferred embodiment, the operation modes include at least an intermittent wiping mode, a low-speed continuous wiping mode, and a high-speed continuous wiping mode.

Specifically, in combination with the above embodiment, the operation 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, which correspond to different magnitudes of the rainfall.

It will be appreciated that the operational modes of the wiper blade also include a stop mode, i.e. when no rain is detected (corresponding to the amount of rain being no rain), the wiper blade is controlled to stop by the wiper motor.

In a further preferred embodiment, the method controls the operating mode of the wiper blade in dependence on the magnitude of the rain detected by the wiper sensor by:

judging the rainfall level according to the rainfall detected by the wiper sensor; wherein the rainfall levels comprise at least a first level, a second level and a third level;

when the rainfall level is the first level, controlling the working mode of the wiper blade to be the intermittent wiping mode;

when the rainfall level is the second level, controlling the working mode of the wiper blade to be the low-speed continuous wiping mode;

and when the rainfall level is the third level, controlling the working mode of the wiper blade to be the high-speed continuous wiping mode.

Specifically, with reference to the above embodiment, the rainfall may be classified according to the magnitude of the rainfall, the classified rainfall classes at least include a first class, a second class and a third class (for example, the first class corresponds to light rain, the second class corresponds to medium rain, and the third class corresponds to heavy rain or heavy rain), and when the working mode of the wiper blade is adjusted according to the magnitude of the rainfall detected by the wiper sensor in real time, the corresponding rainfall class is determined according to the magnitude of the rainfall detected by the wiper sensor; when the rainfall level is judged to be a first level (light rain), the working mode of the wiper blade is controlled to be an intermittent wiping mode through the wiper motor; when the rainfall level is judged to be a second level (medium rain), the working mode of the wiper blade is controlled to be a low-speed continuous wiping mode through the wiper motor; when it is determined that the rainfall level is the third level (heavy rain or heavy rain), the operating mode of the wiper blade is controlled to be a high-speed continuous wiping mode by the wiper motor.

It is understood that the rain-out condition may be classified into a fourth level, and when it is determined that the rain amount level is the fourth level, the operation mode of the wiper blade is controlled to a stop mode, i.e., the wiper blade stops operating, by the wiper motor.

In yet another preferred embodiment, the method further comprises:

when the rain wiper sensor detects that the rain is not rained and the rain wiper action of the rain wiper blade exceeds a preset time threshold value, generating a corresponding dry-wiping alarm signal;

and controlling the wiper blade to stop the wiper action according to the dry-wiping alarm signal.

Specifically, with the above embodiment, when the external environment of the vehicle changes from rain to non-rain, the wiper motor may still control the wiper blade to perform the corresponding wiper action due to some reasons (e.g., the driver forgets to adjust the gear of the wiper switch to the OFF gear, the wiper control system of the vehicle fails, etc.), and at this time, the wiper blade may be dry-wiped (i.e., there is no wiper brush), and the dry-wiped has great damage to the wiper motor and the wiper blade, so when the non-rain is detected by the wiper sensor and the wiper action of the wiper blade exceeds the preset number threshold (e.g., the number of wiper actions after the rain stops is greater than 20), it is determined that the wiper blade is dry-wiped, and a corresponding dry-wiping alarm signal is generated, so that the wiper blade is controlled by the wiper motor to stop the wiper action according to the dry-wiping alarm signal.

According to the control method for the automatic wiper function provided by the embodiment of the invention, the dry wiping prevention operation can be used for preventing the dry wiping condition of the wiper blade when the wiper blade does not rain after the misoperation of a user or the failure of a wiper system, so that the damage to the wiper motor and the wiper blade can be effectively reduced.

In yet another preferred embodiment, the method further comprises:

and sending corresponding text alarm information to a vehicle instrument according to the dry scraping alarm signal.

Specifically, in combination with the above embodiment, when it is detected that the wiper blade is dry-scraped, the corresponding dry-scraping alarm signal is generated to control the wiper blade to stop operating, and the corresponding text alarm information can be generated and sent to the vehicle instrument to remind the driver to check the abnormality of the wiper system, and meanwhile, the corresponding fault code can be recorded to provide reference data for subsequent vehicle maintenance.
