According to the technical scheme, whether the vehicle is in the first state requiring execution of the defogging operation mode or not can be automatically judged through the operation state of the wiper system, the defogging operation mode is automatically executed after the vehicle enters the first state, the driving experience is effectively improved, meanwhile, compared with the prior art that the additional sensor is adopted for analysis and identification, the judgment can be realized through the operation parameters of the existing wiper system of the current vehicle, the accuracy of whether the wiper system is started due to rain is further improved in the judging process, the accuracy of the state that the front windshield glass of the current vehicle is easy to form a fog layer is further improved, and the actual judging and executing effects are greatly improved.

In some embodiments, after the demisting operation mode is performed if the first state is the first state, the method includes the following steps:

and if the closing signal of the defogging function switch is obtained, the defogging working mode is exited, and the judgment of the first state is shielded within a second set time or before the engine is closed.

Through the scheme, under the scene that only the wiper is needed, but the defogging working mode is not needed to be executed, the personnel in the vehicle can be closed after the defogging working mode is automatically opened, and the defogging working mode is not automatically entered according to the working state of the wiper system in a future period or in the driving process, so that the intelligent degree in practical application is improved.

In some embodiments, if the off signal of the defogging operation mode is obtained, the step of exiting the defogging operation mode after the defogging operation mode does not determine whether the vehicle is in the first state within the second set time or in the subsequent process includes the following steps:

and if the starting signal of the defogging function switch is obtained, executing a defogging working mode, and recovering the judgment of the first state in the subsequent stage.

Through the scheme, the first-state judging process is shielded by the driver, but after the defogging working mode is automatically opened according to the requirement, the shielded first-state judging process and the defogging working mode automatic executing process can be recovered, so that the defogging working mode can be automatically carried out in the follow-up driving process when the requirement is met.

In some embodiments, the first state, if present, performs a defogging mode of operation,

and executing the defogging sub-mode corresponding to the working state of the wiper system according to the preset corresponding relation between the working state of the wiper system and a plurality of defogging sub-modes in the defogging working modes.

Through the scheme, after the vehicle is judged to be in the first state, different defogging sub-modes can be further controlled to be executed according to the subdivision working state of the wiper system, and then different environmental conditions are adapted, for example, when the wiper operation speed of the wiper system is higher, the external environment rainfall is higher, the humidity is higher, the speed or the area of forming a fog layer corresponding to glass in the vehicle is higher, the sub-mode with the strongest defogging in the defogging sub-modes can be executed at the moment, and finally the defogging working mode can be correspondingly adjusted according to the working state of the wiper system, so that the defogging effect or the energy-saving effect when the defogging working mode is executed is improved under different environmental conditions.

In some embodiments, the defogging sub-mode corresponding to the working state of the wiper system is executed according to the preset corresponding relation between the working state of different wiper systems and a plurality of defogging sub-modes in the defogging working modes,

the sub-modes of the defogging mode of operation are related to the operational speed and/or period of the wiper blade.

Through the scheme, the fact that a certain defogging sub-mode in the defogging working modes can be judged by only utilizing the running speed and/or the running period of the wiper is achieved, the analysis process is rapid and efficient, the accuracy of reflecting external environment information is high, and the practical effect is high.

In some embodiments, if the wiper system is turned off, the defogging operation mode is exited, or after a third set time, the defogging operation mode is exited, or after a turn-off signal of the defogging function switch is obtained, the defogging operation mode is exited.

Through the scheme, after the vehicle stops raining, the vehicle is still likely to have higher humidity, at this moment, the defogging operation mode is kept until the third set time is finished or the closing signal of the defogging function switch is obtained, and then the defogging operation mode is exited, so that the defogging effect on the glass in the vehicle can be effectively ensured in a certain time after the raining is stopped, and the driving experience is optimized.

and adjusting the vehicle to a target working mode set before the defogging working mode is closed.

By the scheme, when the vehicle exits the defogging working mode, the related equipment in the vehicle can be restored to the working mode before the defogging working mode is started, or the target working mode is adjusted to be new in the defogging working mode, wherein the new target working mode is manually set by personnel in the vehicle or automatically set by a system strategy. For example, in the embodiment in which the vehicle-mounted air conditioner executes the defogging operation mode, if the vehicle-mounted air conditioner is not manually adjusted to a target operation mode by a person or automatically adjusted by a system policy during the execution of the defogging operation mode, the vehicle-mounted air conditioner will resume the operation mode before entering the defogging operation mode when the defogging operation mode exits; if the vehicle-mounted air conditioner is manually adjusted to a target working mode by personnel in the vehicle or automatically adjusted to the target working mode by a system strategy in the execution process of the defogging working mode, when the defogging working mode exits, the vehicle-mounted air conditioner is adjusted to the set target working mode. Finally, interaction between the defogging working mode at the further optimization position and the overall running state of the vehicle when the execution is finished is realized, and driving or riding experience of personnel in the vehicle is further improved.

In some embodiments, when entering the defogging operation mode, if the air conditioner of the vehicle is in an operation state, the air conditioner of the vehicle is switched between a defogging operation and an execution operation before entering the defogging operation mode, or the air conditioner of the vehicle is switched between the defogging operation and a latest operation state of the air conditioner of the vehicle at intervals;

if the vehicle air conditioner is in a closed state, the vehicle air conditioner is maintained in a defogging operation or the defogging operation is performed at intervals.

By means of the scheme, in the embodiment that the air conditioner of the vehicle participates in the defogging operation mode, different operation modes are correspondingly executed by the air conditioner according to the operation state of the air conditioner when the defogging operation mode is entered. When the vehicle enters a defogging working mode, the air conditioner is started, so that the air conditioner has the need of refrigerating or supplying air to the internal environment, and the air conditioner is switched between defogging actions and executing actions before entering the defogging working mode at intervals, so that the defogging and refrigerating/supplying air needs are met; when the vehicle enters the defogging mode, the air conditioner is not started, and the fact that other work is not needed to be executed by the air conditioner in the vehicle at the moment is indicated, so that the vehicle only needs to maintain defogging actions or execute defogging actions according to the required interval of the defogging sub-mode in the defogging mode. The method and the device realize further optimization of the operation effect of the air conditioner when the air conditioner participates in the execution of the defogging operation mode, so that the air conditioner can give consideration to the air conditioner refrigeration/air supply target in the vehicle and the defogging target in the defogging operation mode according to the requirements.

In some embodiments, when it is determined that the defogging mode of operation needs to be exited,

if the air conditioner is in the defogging action, after the defogging action is completed, exiting the defogging working mode;

and if the air conditioner is not in the defogging action, exiting the defogging working mode.

This is easily the case in high numbers such as in rainy days. The common treatment mode during fogging is to adjust the air conditioner to a defrosting mode, and simultaneously start the refrigerating function of the air conditioner, blow dry air flow against the front windshield glass, and volatilize the fog. In the related art, the internal environment state of the vehicle is often judged through signals of additional sensors such as a humidity sensor and a temperature sensor, so that whether the vehicle needs defogging at present is judged, the cost is high, and the vehicle needs to be further improved.

The processor 1001 may call an automatic defogging program of the automobile glass stored in the memory 1005, and execute the automatic defogging method of the automobile glass provided by the embodiment of the application.

In a second aspect, an embodiment of the present application provides an automatic defogging method for automotive glass.

Referring to fig. 2, an automatic defogging method for an automobile glass, comprising:

s100, judging whether the vehicle is in a first state according to the working state of the wiper system; the first state at least corresponds to the state that a washer in the wiper system is in a closed state, and the continuous working time of the wiper motor is longer than a first set time;

and S200, executing a defogging operation mode if the first state is adopted.

In this embodiment, when the washer in the wiper system is not in the working state and the duration of the wiper motor is longer than the first set time, it may be determined that the vehicle is in the first state. Specifically, when the washer is in a working state, it is indicated that the vehicle user is in a working mode in which the vehicle window glass is normally required to be cleaned, but not in a rainy day environment with high humidity, so that the first step of judgment can be performed through the working state of the washer; when the wiper motor is turned off at a time when the on time does not exceed the first set time, the high probability means that the vehicle user erroneously touches the turn signal lamp as the wiper on, and in this state, the user turns off the wiper in a short time, and the situation can be discharged through the continuous working time of the wiper.

In other embodiments, the judgment may be further performed according to the running speed or the running period of the wiper, for example, when the running speed or the running period of the wiper meets a certain value, the rainfall in the environment is larger, that is, the air humidity is larger, the probability of forming a fog layer on the glass in the vehicle is larger, and the defogging working mode may be executed. Therefore, it should be clear that, for the two determination results that the vehicle is in the first state or the vehicle is not in the first state, at least one different operation state can be respectively corresponding, that is, in a certain operation state range of the wiper, whether the wiper is in the first state can be distinguished, and in other embodiments, the correspondence between the different operation states of the wiper system and the different determination results can be set in advance according to different vehicles, different regions or different driving habits, which is not limited by the embodiment of the present application.

In addition, in executing the defogging operation mode, the defogging operation mode may be executed by different vehicle-mounted devices in different embodiments, for example, the vehicle-mounted air conditioner, the vehicle-mounted fresh air device or the drying device may be controlled to execute, which is not limited.

The application can realize judgment only through the working parameters of the existing wiper system of the current vehicle, and the judgment process is limited by the closing state of the washer and the running time of the wiper motor, thereby further improving the accuracy of whether the wiper system is opened due to rain or not, further improving the accuracy of judging the state of easily forming a fog layer of the front windshield glass of the current vehicle, and greatly improving the actual judgment and execution effect.

In some embodiments, if in the first state, after executing the defogging operation mode, the step S200 includes the following steps:

and S300, if a closing signal of the defogging function switch is obtained, exiting the defogging working mode and shielding the judgment of the first state in a second set time or before the engine is closed.

By the arrangement, under the scene that only the wiper is needed, but the defogging working mode is not needed to be executed, the personnel in the vehicle can be closed after the defogging working mode is automatically opened, and the defogging working mode is not automatically entered according to the working state of the wiper system in a future period or in the driving process, so that the intelligent degree in practical application is improved.

In some embodiments, if the off signal of the defogging operation mode is obtained, the step of exiting the defogging operation mode after the defogging operation mode does not determine whether the vehicle is in the first state within the second set time or in the subsequent process includes the following steps:

and S400, if the start signal of the defogging function switch is acquired, executing a defogging working mode, and recovering the judgment of the first state in the subsequent stage.

The setting realizes that the judgment process of the first state is shielded by the driver, but after the defogging working mode is automatically opened according to the requirement, the shielded judgment process of the first state and the automatic execution process of the defogging working mode can be recovered, so that the defogging working mode can be automatically carried out when the driver needs in the subsequent driving process.

Further, in some preferred embodiments, step S200, if in the first state, performs a defogging operation mode,

and executing the defogging sub-mode corresponding to the working state of the wiper system according to the preset corresponding relation between the working state of the wiper system and a plurality of defogging sub-modes in the defogging working modes.

Specifically, after the vehicle is in the first state, different demisting sub-modes can be further controlled and executed according to the subdivision working state of the wiper system, so that different environmental conditions can be adapted, for example, when the wiper running speed of the wiper system is high, the external environment rainfall is high, the humidity is high, the speed or the area of forming a fog layer corresponding to the glass in the vehicle is high, and the sub-mode with the strongest demisting in the demisting sub-modes can be executed. In different embodiments, the wiper system may correspond to different demisting sub-modes through different ranges of parameters such as the operating speed or operating period of the wiper, and in other embodiments, operating parameters of other devices in the wiper system may also be employed.

The defogging mode can be adjusted according to the working state of the wiper system, and defogging effect or energy-saving effect is improved when the defogging mode is executed under different environmental states.

Further, in some embodiments, in step S200, according to the preset correspondence between the working states of different wiper systems and the plurality of defogging sub-modes in the defogging working modes, the defogging sub-modes corresponding to the working states of the wiper systems are executed,

the sub-modes of the defogging mode of operation are related to operational parameters of the wiper blade.

By means of the arrangement, a certain defogging sub-mode in the defogging work modes can be judged only by utilizing the operation parameters of the wiper, the analysis process is rapid and efficient, the accuracy of the external environment information is high, and the practical effect is high.

Further, in this embodiment, the sub-mode of the defogging mode of operation is related to the operating speed and period of the wiper blade operating parameters.

Specifically, when a defogging operation mode is performed by a defogging function of an air conditioner, each defogging sub-mode of the air conditioner is performed by the following different conditions:

defogging every a1 minute and blowing glass b1 minute under the V5 speed/no intermittent mode of the wiper;

the wiper demists once every a2 minutes under the V4 speed/no intermittent mode, and blows glass for b2 minutes;

the windscreen wiper demists once every a3 minutes in a short-time intermittent mode of V3 speed/t 1 intermittent duration, and blows glass for b3 minutes;

the windscreen wiper demists once every a4 minutes in a short-time intermittent mode of V2 speed/t 2 intermittent duration, and blows glass for b4 minutes;

the wiper demists every a5 minutes and blows glass for b5 minutes in a long-time intermittent mode of V1 speed/t 3 intermittent duration.

Wherein V5-V1 decrease in turn, t 1-t 3 increase in turn, a 1-a 5 increase in turn, and b 1-b 2 have the same value.

In addition, in other embodiments, the judging indexes of the running speed and the cycle time of the wiper may be different, for example, V1, V2, V3 are uniformly smaller than the running speed of the wiper in the national standard, and may be equal, and the values of b1 to b2 may be different. The above-described embodiments are merely preferred embodiments of the present embodiment, and are not limited thereto.

Further, in some embodiments, if the wiper system is turned off, the defogging operation mode is exited, or after a third set time, or after a turn-off signal of the defogging function switch is obtained, the defogging operation mode is exited.

In this arrangement, the vehicle interior may still have a high humidity after the vehicle exterior stops raining, at which time by continuing to maintain the defogging operation mode until the third set time is over or the off signal of the defogging function switch is obtained, and the defogging working mode is exited, so that defogging effect on glass in the vehicle can be effectively guaranteed within a certain time after the rain is stopped, and driving experience is optimized.

Further, in some preferred embodiments, if the defogging mode of operation is exited and the vehicle is restored to the pre-defogging mode of operation, or,

and adjusting the vehicle to a target working mode set before the defogging working mode is closed.

Specifically, when the vehicle exits the defogging working mode, the related equipment in the vehicle can be restored to the working mode before the defogging working mode is started, or the target working mode is adjusted to a new target working mode which is manually set by personnel in the vehicle or automatically set by a system strategy in the defogging working mode. For example, in the embodiment in which the vehicle-mounted air conditioner executes the defogging operation mode, if the vehicle-mounted air conditioner is not manually adjusted to a target operation mode by a person or automatically adjusted by a system policy during the execution of the defogging operation mode, the vehicle-mounted air conditioner will resume the operation mode before entering the defogging operation mode when the defogging operation mode exits; if the vehicle-mounted air conditioner is manually adjusted to a target working mode by personnel in the vehicle or automatically adjusted to the target working mode by a system strategy in the execution process of the defogging working mode, when the defogging working mode exits, the vehicle-mounted air conditioner is adjusted to the set target working mode.

By the arrangement, interaction between the defogging working mode at the further optimization position and the overall running state of the vehicle when the execution is finished is realized, and driving or riding experience of personnel in the vehicle is further improved.

Further, when entering the defogging operation mode, if the air conditioner of the vehicle is in an operation state, the vehicle air conditioner is switched between the defogging operation and the execution operation before entering the defogging operation mode, or the vehicle air conditioner is switched between the defogging operation and the latest operation state of the vehicle air conditioner at intervals;

if the vehicle air conditioner is in a closed state, the vehicle air conditioner is maintained in a defogging operation or the defogging operation is performed at intervals.

Specifically, in the embodiment where the air conditioner of the vehicle participates in the defogging operation mode, different operation modes of the air conditioner are controlled correspondingly according to the operation state of the air conditioner when the defogging operation mode is entered. When the vehicle enters a defogging working mode, the air conditioner is started, so that the air conditioner has the need of refrigerating or supplying air to the internal environment, and the air conditioner is switched between defogging actions and executing actions before entering the defogging working mode at intervals, so that the defogging and refrigerating/supplying air needs are met; when the vehicle enters the defogging mode, the air conditioner is not started, and the fact that other work is not needed to be executed by the air conditioner in the vehicle at the moment is indicated, so that the vehicle only needs to maintain defogging actions or execute defogging actions according to the required interval of the defogging sub-mode in the defogging mode.

The device is arranged in such a way, the operation effect of the air conditioner when the air conditioner participates in the execution of the defogging operation mode is further optimized, and the air conditioner refrigeration/air supply target in the vehicle and the defogging target in the defogging operation mode can be considered according to the requirements.

Further, in some preferred embodiments, in different ones of the demisting sub-modes, the vehicle air conditioner has a different duration of interval between adjacent demisting actions.

By the arrangement, the defogging operation of the vehicle glass is carried out in different defogging sub-modes at a proper frequency according to different working states of the wiper system.

Specifically, for specific parameters of different interval durations between demisting actions in different demisting sub-modes, the correspondence setting may be performed in advance, which is not limited herein.

Further, in some preferred embodiments, when it is determined that the defogging mode of operation needs to be exited,

if the air conditioner is in the defogging action, after the defogging action is completed, exiting the defogging working mode;

and if the air conditioner is not in the defogging action, exiting the defogging working mode.

By the arrangement, when the demisting working mode is exited, the air conditioner participating in executing the demisting working mode can exit the demisting working mode more smoothly.
