Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
In addition, the "rainfall" mentioned in the embodiments of the present invention shall include the case of snowfall, just as vehicle wipers are used not only to sweep the front window rain but also to sweep the front window snow.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example one
Fig. 1 is a flowchart illustrating a vehicle control method using a wiper according to an embodiment of the present invention, and the method is applied to a vehicle-mounted terminal, for example, a tbox (telematics box).
Referring to fig. 1, the vehicle control method using the wiper may include the steps of:
in step S110, a wiper operating state signal is acquired.
The windshield wiper working state signal is used for showing the corresponding relation between the rainfall level and the windshield wiper brushing frequency. For example, the greater the rainfall level, the greater the wiper brushing frequency. Preferably, the wiper may be set to four operation modes, from low to high in wiper frequency and corresponding to rainfall levels of "no rain", "light rain", "medium rain" and "heavy rain", respectively, according to the wiper frequency, that is: normal windshield wiper swing, automatic intermittent swing, continuous low-speed swing and continuous high-speed swing. Therefore, different working modes correspond to different rainfall levels and different wiper brushing frequencies, and different wiper working state signals can be configured to show the different working modes so as to achieve the purpose of indirectly showing the corresponding relation between the rainfall levels and the wiper brushing frequencies, for example, four wiper working state signals of '0', '1', '2' and '3' can be configured to respectively show four working modes of normal wiper swinging, automatic intermittent swinging, continuous low-speed swinging and continuous high-speed swinging. For convenience of description, an exemplary relationship among the wiper operation state signal, the wiper operation mode, the wiper frequency, and the rainfall level is shown herein by table 1, which can be understood hereinafter with reference to table 1.
TABLE 1 signal of operating state of windshield wiper
It should be noted that, in the first embodiment, the vehicle-mounted terminal may directly obtain the wiper operating state signal from the wiper controller of the vehicle, and details of obtaining the wiper operating state signal by the wiper controller will be described in relevant parts below, which are not described herein again.
In addition, unlike the host vehicle and other vehicles, the step S100 may include the following two implementations:
1) and acquiring a wiper working state signal from a wiper controller of the vehicle through the vehicle gateway. For example, a wiper controller of the vehicle obtains a wiper working state signal and sends the wiper working state signal to a vehicle gateway, and the gateway forwards the wiper working state signal to the TBOX.
2) And acquiring the wiper working state signals from other vehicles except the vehicle through the remote server. For example, for an internet of vehicles system composed of a plurality of vehicles and a remote server (TSP, for example), the TBOX of the host vehicle may obtain the TBOX of the other vehicle from the TSP and report the TBOX of the other vehicle to the wiper operating state signal of the TSP, so as to analyze the rainfall condition of the area where the other vehicle is located. The analysis of the rainfall in the area where the other vehicle is located is similar to the analysis of the rainfall in the area where the vehicle is located according to the operating state signal of the wiper of the vehicle in the following step S120, and therefore, the detailed description thereof is omitted here.
And step S120, determining a current rainfall level signal according to the acquired wiper working state signal.
In the following, the step S120 is directed to a situation where the rainfall condition of the area where the host vehicle is located is analyzed according to the host vehicle wiper operation state signal. For example, referring to table 1, when the wiper operating state signal is "3", TBOX determines that the wiper is in the continuous high-speed swing operating mode, where the wiper frequency is the highest level and the corresponding rainfall level is heavy rain.
Step S130, sending the determined current rainfall level signal to a vehicle component so as to enable the vehicle component to work according to the current rainfall level signal.
The phrase "the vehicle component performs the operation adapted to the current rainfall level signal" means that the vehicle component performs the operation in a manner meeting the driving safety requirement in rainy days and/or the driving experience requirement in rainy days, for example, in heavy rain, the vehicle component operates to improve the braking sensitivity, maintain the driving distance with the front vehicle, maintain the proper temperature in the vehicle, and the like.
For example, the vehicle components may be pre-configured with different operating modes corresponding to different levels of rainfall, so that the vehicle may be controlled differently depending on the rainfall. It should be noted that, different operation modes of each vehicle component responding to different rainfall levels will be described below, and detailed description thereof is omitted here.
In summary, the vehicle control method according to the embodiment of the invention can determine the current rainfall level through the working state of the windshield wiper, and make the vehicle component adapt to the current rainfall level to work, which is beneficial to ensuring the driving safety and driving experience in rainy days.
Example two
The second embodiment of the invention provides an in-vehicle terminal which is provided with a controller, and the controller is configured to execute the vehicle control method by using the wiper in the first embodiment.
Fig. 2 is a functional block diagram of an example implementation manner of the in-vehicle terminal according to the second embodiment of the present invention. As shown in fig. 2, the in-vehicle terminal 200 may include a control module 210 and a communication module 220. The control module 210 is the controller for executing the vehicle control method using the wiper according to the first embodiment, and is configured to: after receiving the wiper working state signal, determining a current rainfall level signal according to a preset logic algorithm, and controlling the work of vehicle components according to the rainfall level signal. The control module 210 can be implemented by a conventional controller such as a single chip, a digital signal processor, etc. Further, the communication module 220 is mainly used for establishing communication between the vehicle and a remote server, so that the control module 210 can send or receive related signals to or from the remote server.
Further, the in-vehicle terminal 200 may be a TBOX, and the current TBOX has functional modules that can implement the control module 210 and the communication module 220, and only needs to be adaptively configured according to requirements of an embodiment of the present invention.
For details and effects of the second embodiment, reference may be made to the first embodiment, and further description is omitted here.
EXAMPLE III
Fig. 3 is a schematic structural diagram of a vehicle control system using a wiper according to a third embodiment of the present invention. As shown in fig. 3, the vehicle control system 300 using a wiper may include: the wiper controller 310 is configured to control a wiper to enter different working modes corresponding to different initial rainfall levels when rainfall occurs, and determine a wiper working state signal corresponding to the current working mode of the wiper according to the pre-configured corresponding relationship between the different working modes of the wiper and different wiper working state signals, wherein the wiper working frequency corresponding to each working mode of the wiper is different, and the wiper working state signal is used for showing the corresponding relationship between the rainfall level and the wiper working frequency; the vehicle-mounted terminal 200 according to the second embodiment is configured to obtain the wiper operating state signal from the wiper controller 310, determine a current rainfall level signal according to the wiper operating state signal, and send the determined current rainfall level signal to a vehicle component; and the vehicle component 320 configured to perform operations adapted to the current rainfall level signal.
The relation among the wiper operating state signal, the wiper operating mode, the wiper brushing frequency, and the rainfall level may be understood with reference to the first embodiment and table 1, and will not be described herein again. For example, using the relationship shown in table 1, a certain logic algorithm may be configured inside the wiper controller 310, and further the wiper operating state signal may be determined according to the current operating mode of the wiper, for example, referring to table 1, when the current operating mode of the wiper is "automatic intermittent oscillation", the wiper operating state signal is determined to be 1.
In a preferred embodiment, the wiper controller 310 determines whether there is rainfall according to a rainfall signal sent by the rainfall sensor, and determines an initial rainfall level according to a wiper swing frequency during the initial rainfall, and then determines a working mode corresponding to the wiper according to the initial rainfall level. That is, the vehicle control system 300 using the wiper may further include: and the rainfall sensor 330 is used for detecting a rainfall signal and sending the rainfall signal to the wiper controller. For example, when rainfall occurs in a certain area, the rainfall sensor 330 of the vehicle running on rainy days detects the rainfall and sends a rainfall signal to the wiper controller 310, so that the wiper controller 310 controls the wiper to automatically operate and starts to determine a rainfall level signal, and as the rainfall level signal is different, the wiping frequency of the wiper is different, and thus the operating mode of the wiper is different.
Further, the vehicle component 320 may include a safety device and/or an experience device of the vehicle, and: the safety device is configured to implement a safety level adapted to the current rainfall level signal, wherein the higher the rainfall level, the higher the safety level; the experiential device is configured to perform a user experience level adapted to the current rainfall level signal, wherein each rainfall level is preconfigured with a corresponding user experience level.
The following describes the work of the safety device and the experience device of the vehicle, which is adapted to the current rainfall level signal.
1) A safety device.
The safety device is a System or a component for controlling driving safety in a vehicle, and may include, for example, an Anti-lock Braking System (ABS) of the vehicle, an Electronic Stability Program (ESP) of the vehicle, an automatic Emergency Braking System (AEB), and/or a Traction Control System (TCS). Wherein, for example, ABS, ESP, AEB and TCS each have their respective Electronic Control Units (ECUs), so that an on-board terminal, such as TBOX, can send said rainfall level signal to each ECU to cause the respective ECU to Control the relevant vehicle component.
For an ABS system, a rubber air bag in a valve body is utilized to give brake oil pressure to fill the valve body of the ABS when a brake is stepped on, and the air bag returns the pressure by utilizing an air interlayer in the middle to enable wheels to avoid dead locking points; when the wheel is about to reach the next dead point, the pressure of the brake oil enables the air bag to act repeatedly, and therefore the air bag can act for 60-120 times in one second, namely the braking and the loosening are ceaselessly performed, namely the mechanical 'inching' brake is similar. Preferably, the safety level of the ABS can be divided into three levels of one, two and three according to different times of 'point braking' in one second, the number of point braking in the three-mode of the safety level is 60-80, the number of point braking in the two-mode of the safety level is 80-100, the number of point braking in the one-mode of the safety level is 100-120, and the braking distances of the vehicles in different safety levels are different. When the ABS receives different rainfall levels (three levels, such as light rain, medium rain and heavy rain), the safety level (three levels, two levels and one level) of the ABS is adjusted to different safety protection states to prevent dangers caused by excessive rainfall.
For an ESP system, based on an ABS system, information such as the rotation angle and the lateral acceleration of a steering wheel is collected through a peripheral sensor, and a hydraulic regulator sends a braking instruction to a wheel brake to realize the correction of sideslip. Preferably, the safety level of the ESP (or called the stability level of the vehicle) can be classified into three levels, i.e., one, two and three, according to the different sensitivity states of the sensor, and the ESP in different level states has different sensitivity and sideslip prevention capability. The ESP adjusts the stability level (third, second, first) of the vehicle to different safety protection states according to the received rainfall level (three levels, e.g., light rain, medium rain, heavy rain) to prevent danger due to excessive rainfall.
For the AEB system and the TCS system, the former is mainly used to ensure that the vehicle keeps a safe driving distance from the front vehicle, and the latter is mainly used to provide vehicle traction, both of which can refer to the safety level division of the ABS system and the ESP system to perform work adapted to the current rainfall level signal, and are not described herein again.
It should be noted that in other examples, the windshield wiper, the windshield and the like may belong to a safety device, and the embodiment of the present invention may also control them to adapt to the current rainfall level operation to cope with the weather change.
2) Experience type device
The experience-based device refers to a system or a component for enhancing user experience in a vehicle, and may include a Host Unit (HUT) of the vehicle, an air conditioner and/or a seat (a seat with a heating function), for example. Wherein the HUT is configured to execute a multimedia service mode adapted to the current rainfall level signal, the air conditioner is configured to adjust an in-vehicle temperature adapted to the current rainfall level signal, and the seat is configured to adjust a seat heating level adapted to the current rainfall level signal.
For example, after receiving a rainfall level signal sent by the TBOX, the HUT performs different rainy day modes according to the received rainfall level, and in different rainy day modes, the multimedia managed by the HUT plays different types of music to relieve the mood of the user, and pushes some movies related to rainy days for viewing by copiers and back row passengers or pushes some news brought by rainfall to the traffic for the user to know.
For example, for an air conditioner, the temperature in the vehicle is adjusted according to the received rainfall level, and the automatically adjusted temperature of the air conditioner may be different according to different rainfall levels.
For example, for a seat, it may also adjust the level of seat heating to a corresponding level based on the level of rainfall received.
For the above-mentioned safety type device and experience type device, the TBOX can separately transmit the rainfall level signal to them and their included components to separately control the operation of each component, for example, in case that the user does not want to listen to music or watch movies, the safety type device, the air conditioner and the seat can be operated only in the rainfall level adaptation, without starting the HUT to play music or videos.
Additionally, in a preferred embodiment, TBOX also provides one-click unified control of all components of the safety and experiential devices operating simultaneously in response to rainfall levels. Fig. 4 is a schematic configuration diagram of a vehicle control system using a wiper of the preferred embodiment. As shown in fig. 4, in the preferred embodiment, the vehicle control system 300 using a wiper may further include: a vehicle controller 340, in communication with the in-vehicle terminal 200 and the vehicle component 320, configured to initiate a preset rainy day mode in response to acquiring the current rainfall level signal from the in-vehicle terminal 200, wherein in the rainy day mode, the vehicle component 320 performs an operation adapted to the current rainfall level signal.
That is, the rain mode for all vehicle components is set by the vehicle controller 340, and the rain mode can be activated by one key to achieve the purpose of uniformly controlling all vehicle components to work according to the current rainfall level signal. For example, through the vehicle controller 340, the entire vehicle starts a rainy day mode, the ABS starts an emergency mode to improve its sensitivity, the AEB maintains a driving distance from the preceding vehicle, and the vehicle automatically adjusts the air conditioner to a suitable temperature according to the rainfall condition, and the HUT plays related music according to the rainfall condition.
Wherein, for the electric vehicle, the vehicle controller may be a VCU (vehicle control unit); for a Hybrid vehicle, the vehicle controller is an HCU (Hybrid Control Unit, Hybrid vehicle Control Unit); in addition, the vehicle controller may also be a BCM (Body Control Module).
Returning to fig. 3 and 4, in a preferred embodiment, the vehicle control system 300 using a wiper may further include: and a remote server 350, in communication with the vehicle-mounted terminal 200, configured to acquire and transmit a current rainfall level signal determined by the vehicle-mounted terminal of the vehicle, and/or transmit a current rainfall level signal from another vehicle to the vehicle-mounted terminal of the vehicle.
For example, for a vehicle a about to travel to a certain area a, a rainfall level signal of a vehicle B currently located in the area a is acquired from the TSP through the internet of vehicles, and function adjustment of the entire vehicle is performed according to the rainfall level signal, so as to ensure that the vehicle a can travel in response to the rainfall condition of the area a when reaching the area a. For another example, the vehicle a may transmit the rainfall level signal of the current area B where the vehicle a is located, which is determined by its on-board terminal, to the TSP, and the TSP may transmit the rainfall level signal to other vehicle references in the same internet of vehicles, or provide the signal to the relevant weather prediction department as a reference.
According to experiments, the scheme for forecasting rainfall by using the working state of the windshield wiper in the embodiment of the invention has better pertinence and real-time performance on rainfall forecasting data of a specified small-range area compared with the existing scheme for forecasting the weather of a large-range area by using a meteorological satellite. Therefore, government departments, communities, vehicles and the like can take actions by utilizing the data with better pertinence and real-time performance, for example, the government departments can take flood prevention measures according to the data acquired from the vehicle in the internet of vehicles, the communities can take waterproof measures on houses, infrastructures and the environment, and the vehicles can carry out driving adjustment corresponding to rain conditions.
Fig. 5 is a schematic flowchart of an example work flow of rainfall countermeasure and prediction performed by the vehicle control system according to the third embodiment of the present invention, in this example, the vehicle-mounted terminal is TBOX, and the remote server is TSP. As shown in FIG. 5, the example workflow may include the following steps:
in step S501, when the rainfall sensor detects rainfall, the wiper controller controls the wiper to automatically operate.
In step S502, the wiper controller determines a wiper operating state signal and sends it to TBOX.
The determination scheme of the wiper operating state signal may refer to the above, and is not described herein again.
In step S503, TBOX determines the current rainfall level signal according to the wiper operating state signal, and then step S504a or step S504b is executed.
In step S504a, TBOX sends a current rainfall level signal to the vehicle components.
In step S504b, TBOX sends the current rainfall level signal to TSP.
Corresponding to step S504a, step S505a is configured to: the vehicle components perform work adapted to the current rainfall level signal.
Corresponding to step S504b, step S505b is configured to: and the TSP transmits the current rainfall level signal based on the Internet of vehicles.
By the example, it can be known that the vehicle control system according to the embodiment of the present invention can determine the current rainfall level through the wiper operating state, and adapt the vehicle component to the current rainfall level to operate, which is beneficial to ensuring driving safety and driving experience in rainy days, and can provide the determined current rainfall level to the TSP to realize rainfall prediction. The rainfall prediction provided by the example is better in real-time performance relative to a conventional weather prediction scheme when aiming at a small-range area.
