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.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. The cases of "target", "original", etc. are similar and will not be described in detail herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Before the embodiments of the present invention are described, an application scenario of the embodiments of the present invention is described as an example. For example, the vehicle Control method according to the embodiment of the present invention may be applied to an Electronic Control Unit (ECU), where the ECU is located in a vehicle Control system disposed on a target vehicle, and the vehicle Control system may further include a rainy day mode switch, a wiper module, a rearview mirror heating module, and a rear windshield heating module.

Fig. 1 is a flowchart of an automobile control method provided in an embodiment of the present invention. The present embodiment is applicable to a case where the field of view of the driver is enlarged, and particularly, to a case where the field of view of the front, rear, and both sides of the driver is enlarged. The method can be executed by the automobile control device provided by the embodiment of the invention, the device can be realized by software and/or hardware, and the device can be integrated on an ECU.

Referring to fig. 1, the method of the embodiment of the present invention specifically includes the following steps:

and S110, under the condition that the mode switch is in an on state in rainy days, controlling a wiper arranged on a front windshield of the target automobile to wipe through a wiper module.

In order to ensure the driving safety in the rain, the wiper arranged on the front windshield of the target automobile can be controlled by the wiper module to wipe and brush so as to reduce water drops on the front windshield, thereby expanding the visual field range in front of the driver, which is an important means for ensuring the driving safety.

And S120, heating the rearview mirror on the target automobile through a rearview mirror heating module.

In order to ensure driving safety to the maximum extent, the visual field range in front of the driver can be enlarged, and the visual field ranges behind and on two sides of the driver can be enlarged. For this reason, it is considered that a large amount of water drops easily appear on the rearview mirror of the target vehicle in driving in the rain, particularly in the case of driving in heavy rain, which reduces the visual field range on both sides of the driver, thereby causing the driver to be unable to see nearby vehicles when changing lanes. Therefore, in order to enlarge the visual field range of both sides of the driver, the rearview mirror can be heated by the rearview mirror heating module, so that water drops on the rearview mirror are reduced.

In practice, the rear view mirror here may alternatively be understood as an exterior rear view mirror arranged outside the target vehicle, as opposed to an interior rear view mirror arranged inside the target vehicle.

And S130, heating the rear windshield on the target automobile through the rear windshield heating module.

Wherein, similar with last step, appear a large amount of drops of water easily on the rear windshield of the target car that drives in the rain, this can lead to the driver can't see the rear vehicle clearly through interior rear-view mirror, has reduced the field of vision scope at driver's rear. Therefore, in order to enlarge the field of view behind the driver, the rear windshield may be heated by the rear windshield heating module, thereby reducing water droplets on the rear windshield.

An optional technical solution, the vehicle control system may further include: the rainfall sensor, the above-mentioned car control method may further include: acquiring the current rainfall through a rainfall sensor; according to the current rainfall, the wiping speed of the wiper is controlled by the wiper module and the heating power of the rearview mirror is controlled by the rearview mirror heating module. Wherein, the rainfall sensor can be used for detecting current rainfall size, consequently can acquire current rainfall size through the rainfall sensor. On the basis, the wiping speed of the wiper can be controlled by the wiper module according to the current rainfall so that the wiping speed is matched with the current rainfall, for example, when the current rainfall is large, the wiping speed is high; when the current rainfall is less, scrape the brush speed and be slower to the visual field scope in assurance driver the place ahead that all can be better under various circumstances. In addition, the heating power of the rearview mirror can be controlled through the rearview mirror heating module according to the current rainfall so that the heating power is matched with the current rainfall, and if the current rainfall is large, the heating power is large; when the current rainfall is smaller, the heating power is lower, so that the rear view range of the driver can be better ensured under various conditions.

Alternatively, the vehicle control system may further include: the defogging module, the above-mentioned car control method may further include: and the fog on the front windshield is removed through the defogging module. In rainy days, the temperature outside the vehicle is likely to be lower, and the temperature inside the vehicle is likely to be higher, at the moment, fog is likely to appear on one side of the inner side of the front windshield, and the fog can also seriously affect the visual field range of a driver. For this purpose, the defogging module may be used to remove fog from the front windshield, thereby further increasing the field of view in front of the driver.

Another optional technical solution, the vehicle control system may further include: light module, light control switch and light sensor, above-mentioned automobile control method can also include: under the condition that the rainy day mode switch is switched from the on state to the off state, if the light control switch is in the off state, the current light intensity is obtained through the light sensor; and if the current light intensity is smaller than the preset light intensity threshold value, switching the light control switch from the off state to the on state through the light module so as to light the lamp of the target automobile.

When the switch is switched from the on state to the off state in the rainy day, which indicates that the rain stops, it may be determined whether the light control switch is in the off state or the on state. If the light control switch is in the on state, the light on the target automobile is lightened, otherwise, the light on the target automobile is not lightened. On the basis, for the condition that the light control switch is in the on state, which indicates that the lamp on the target automobile is lighted before raining, the on state can be continuously maintained in order to ensure the driving safety. To the condition that light control switch is in the off-state, this shows that the car light is not lighted before raining, but consider that in this period of time raining, the light outside the car may obviously change, especially may change from the time of the day to the time of the day dark, therefore in order to guarantee driving safety, can acquire the current light intensity through light sensor, and be less than the predetermined light intensity threshold value at current light intensity, namely under the darker condition outside the car, switch light control switch from the off-state to the on-state through the light module, with the car light of lighting, thereby avoid appearing when withdrawing from the rainy day mode, because the car outer is darker and lead to the condition that the driver can't see the road conditions clearly.

On this basis, optionally, if the light control switch is in the off state, obtaining the current light intensity through the light sensor may include: if the light control switch is in a closed state, acquiring the current time and the current position of the target automobile, and determining the sunrise and sunset time corresponding to the current position according to the current time; and under the condition that the target automobile is determined to be in a daytime mode according to the current time and the sunrise and sunset time, the current light intensity is obtained through the light sensor.

In this case, it is considered that the light outside the vehicle is variable when the target vehicle is in the daytime mode (or after sunrise and before sunset), for example, the light outside the vehicle is brighter on a sunny day and darker on a cloudy day. In contrast, when the target vehicle is in the night mode, that is, the target vehicle is traveling at night (or before sunrise and after sunrise), the external light is probably darker. Therefore, for the target automobile in the night mode, in order to ensure the driving safety, the light control switch can be directly switched from the off state to the on state at the moment so as to light the lamp; for the target automobile in the daytime mode, whether the on-off state of the light control switch needs to be switched or not can be judged according to the current light intensity, so that the automobile light is lightened when needed, the driving safety of a driver is guaranteed, and the electric energy on the target automobile is saved.

On the basis, the day mode and the night mode can be judged according to the current time and the sunrise and sunset time, wherein the sunrise and sunset time can include sunrise time and sunset time, for example, when the current time is between the sunrise time and the sunset time, the day mode can be considered at this time, otherwise, the night mode can be considered at this time. In addition, the sunrise and sunset time can be determined according to the current time and the current position of the target automobile, because the current time can reflect the current days of several months, the current position can reflect the geographic position of the target automobile, and then the sunrise and sunset time can be obtained by combining the current time with the current position.

In order to better understand the above technical solutions as a whole, the following description is given by way of example with reference to specific examples. For example, referring to fig. 2, an automotive control system may include: the device comprises a voice module, a rainfall light sensor (RLS sensor), a rainy day mode switch, a light control switch, a dipped headlight module, a signal storage module, a power module, a position light module, a steering lamp module, a wiper module, a rearview mirror heating module, a rear windshield heating module and a demisting module. In particular, the method comprises the following steps of,

the RLS sensor can be used for detecting the current rainfall and the current light intensity, the ECU can control the wiping speed of the wiper according to the current rainfall, and the RLS sensor is communicated with the ECU through a LIN bus. The low beam light module, the position light module and the turn light module provide the function of turning on and off the light, and these three modules communicate with the ECU through the LIN bus. The wiper module may control the opening and closing of the wiper and the wiping speed through the ECU, which communicates with the ECU through the LIN bus. When the rearview mirror heating module is started in a rainy day mode, the rearview mirror heating function CAN be automatically started, so that the rearview mirror is heated, the heating power CAN be controlled according to the current rainfall, and the rearview mirror heating module is communicated with the ECU through a CAN bus. The rear air window heating module is used for heating the rear air window and is communicated with the ECU through a CAN bus. The defogging module can be used for removing fog on the front windshield. The rainy day mode switch is used for opening and closing a rainy day mode, when the rainy day mode is opened, the position lamp module, the steering lamp module, the rearview mirror heating module, the rear windshield heating module and the defogging module can be automatically opened, and the headlamp is set to be in an automatic mode to automatically open light, so that the visual field range can be enlarged, the headlamp can be conveniently identified by other vehicles, and the driving safety is further guaranteed. The voice module can be used for controlling the on and off of the rainy day mode. The signal storage module can be used for storing the voice signal set, so that the voice signal set is read from the signal storage module when the system is powered on to be matched with a voice instruction sent by a driver and a passenger of a target automobile. The power supply module can be used for supplying power to the system and is connected with the storage battery.

FIG. 3 is a flow chart of another method of controlling a vehicle provided in an embodiment of the present invention. The present embodiment is optimized based on the above technical solutions. In this embodiment, optionally, the vehicle control system may further include: the automobile control method further comprises the following steps: acquiring a voice instruction through a voice module; and determining to set the rainy-day mode switch to be in an opening state or a closing state according to the voice instruction. The same or corresponding terms as those in the above embodiments are not explained in detail herein.

Referring to fig. 3, the method of this embodiment may specifically include the following steps:

s210, a voice instruction is obtained through the voice module, and the rainy day mode switch is set to be in an opening state or a closing state according to the voice instruction.

The method comprises the steps that a voice command for setting the on-off state of a rainy day mode switch is collected through a voice module, the voice command can be sent by a driver or a passenger on a target automobile, and the driver or the passenger can be a driver or a passenger; or by other persons located outside the target vehicle; and the like, are not specifically limited herein. After the voice instruction is acquired through the voice module, whether the rainy day mode switch is set to be in an opening state or a closing state can be determined according to the voice instruction.

And S220, under the condition that the mode switch is in the on state in rainy days, controlling a wiper arranged on a front windshield of the target automobile to wipe through a wiper module.

And S230, heating the rearview mirror on the target automobile through the rearview mirror heating module.

And S240, heating the rear windshield on the target automobile through the rear windshield heating module.

According to the technical scheme of the embodiment of the invention, the voice instruction is obtained through the voice module, and the rainy day mode switch is determined to be in the opening state or the closing state according to the voice instruction, so that the effect of automatically controlling the rainy day mode to enter or exit through the voice instruction is realized, and the method has the advantages of being simple in operation and high in response efficiency, thereby reducing the labor degree of drivers and passengers, and reducing the probability of accidents occurring during driving in rainy days.

An optional technical solution, the vehicle control system may further include: the signal storage module, which stores a pre-collected voice signal set, determines to set the rainy mode switch to the on state or the off state according to the voice instruction, and may include: determining whether a voice signal matched with the voice instruction exists in the voice signal set or not aiming at the voice signal set read from the signal storage module; and if so, determining whether the rainy day mode switch is set to be in an opening state or a closing state according to the voice signal. The signal storage module stores a pre-collected voice signal set, and the voice signal set comprises at least one candidate signal. Thus, after the voice command is acquired, it can be determined whether a candidate signal matching the voice command exists in the voice signal set, and such candidate signal can be referred to as a voice signal for distinguishing from the remaining candidate signals. For example, assuming that one candidate signal in the set of speech signals is to turn on the rainy mode and the other candidate signal is to turn off the rainy mode, the speech signal may be to turn on the rainy mode when the speech instruction is to enter the rainy mode. If the voice signal is present, the on-off state of the rainy mode switch may be set according to the voice signal. According to the technical scheme, the voice signals collected in advance can accelerate the setting speed of the on-off state and improve the setting precision of the on-off state.

On this basis, optionally, the vehicle control method may further include: acquiring candidate signals through a voice module, and learning the candidate signals to obtain control commands represented by the candidate signals; forming a voice signal set based on the collected candidate signals, and storing the voice signal set into a signal storage module; accordingly, determining whether to set the rainy day mode switch to the on state or the off state according to the voice signal may include: and determining to set the rainy day mode switch to be in an opening state or a closing state according to the control command represented by the voice signal. For each candidate signal, learning the candidate signal, or performing speech recognition on the candidate signal, to obtain a control command represented by the candidate signal, for example, when the candidate signal is in the on-rainy mode, the corresponding control command may include setting the on-off state of the switch in the rainy mode to the on-off state; when the candidate signal is to turn off the rainy mode, the corresponding control command may be to set the on-off state of the rainy mode switch to the off state. Therefore, after the voice signal is obtained from the voice signal set, the voice signal is the candidate signal corresponding to the voice command in each candidate signal, so that the switching state can be set according to the control command represented by the voice signal, and the setting precision of the switching state is ensured.

In order to better understand the technical solutions set forth in the embodiments of the present invention as a whole, the following description is made by way of example with reference to specific examples.
