Description

Technical Field

[0001] This invention relates to the field of vehicle windshield wiper control, and more specifically to a windshield wiper control method, device, vehicle, and storage medium. Background Technology

[0002] Windshield wipers are an essential component of any vehicle, used to remove raindrops and dust from the windshield to improve driver visibility and increase driving safety. Traditionally, wiper operation is controlled by the instrument panel, with the driver operating a wiper lever; alternatively, a rain sensor is installed on the windshield, which determines rain level by how raindrops affect light levels, and then activates the wipers accordingly. With the increasing automation and integration of new energy vehicles, intelligent features are gaining popularity. To enhance user experience, improve intelligent driving safety, and meet users' intelligent needs, proactively activating the wipers before exiting tunnels, based on weather and surrounding conditions, provides enhanced driving safety.

[0003] In related technologies, patent [CN101797913A] proposes an intelligent wiper system and its control method, including an intelligent wiper controller, a wiper actuator, a mode switch, and a rain sensor. The intelligent wiper controller is integrated into the vehicle body controller and controls the wiper actuator via a pin. The rain sensor and mode switch communicate with the intelligent wiper controller via LIN (Local Interconnect Network). The vehicle body controller with the integrated intelligent wiper controller acts as both a node in the CAN (Controller Area Network) network and a master node in the LIN network. This invention integrates the intelligent wiper controller inside the vehicle body controller. The controller obtains control commands and rain detection information through the LIN bus, thereby driving and controlling the washer motor, wiper motor, or wiper telescopic motor. Simultaneously, it transmits information from the intelligent wiper system to other modules of the vehicle via the CAN bus, achieving information sharing.

[0004] However, this method still controls the wiper controller by the effect of raindrops on the rain sensor, and cannot control the wipers to turn on before exiting the tunnel based on the weather and environmental information provided by the vehicle. This problem urgently needs to be solved. Summary of the Invention

[0005] One objective of this invention is to provide a windshield wiper control method to solve the problem of traffic accidents caused by windshield wipers not opening in time when a vehicle exits a tunnel; a second objective is to provide a windshield wiper control device; a third objective is to provide a vehicle; and a fourth objective is to provide a computer-readable storage medium.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for controlling a windshield wiper includes the following steps:

[0008] Determine if there is a tunnel ahead of the current vehicle;

[0009] If a tunnel exists ahead of the current vehicle, the length of the tunnel and weather information at the current vehicle's location are obtained, and the windshield wiper operating parameters of the current vehicle are determined based on the length and the weather information; and

[0010] The windshield wipers of the current vehicle are controlled to perform corresponding actions based on the wiper operating parameters.

[0011] Based on the aforementioned technical means, the windshield wipers can be intelligently controlled to turn on before the vehicle exits the tunnel, according to the weather conditions and the surrounding environment. This solves the problem of traffic accidents caused by windshield wipers not turning on in time when the vehicle exits the tunnel, and improves road traffic safety.

[0012] Further, determining the windshield wiper operating parameters of the current vehicle based on the length and the weather information includes:

[0013] Determine whether the length is less than or equal to a first preset length;

[0014] If the length is less than or equal to the first preset length, then obtain environmental information in front of the tunnel exit that meets the preset visibility requirements;

[0015] Based on the environmental information and the weather information, the windshield wiper operating parameters of the current vehicle are determined from a preset windshield wiper control parameter table.

[0016] Based on the above technical means, when the tunnel length is less than or equal to the preset length, environmental information within the visibility range in front of the tunnel exit is obtained, and the windshield wiper operating parameters are determined according to the weather and environmental information, so as to achieve appropriate control of the windshield wipers for different rainy days.

[0017] Furthermore, after determining whether the length is less than or equal to the first preset length, the method further includes:

[0018] If the length is greater than the first preset length, then the first distance between the current vehicle and the tunnel exit is obtained;

[0019] If the first distance is less than or equal to the first preset distance, then the step of obtaining environmental information in front of the tunnel exit that meets the preset visibility requirements is executed.

[0020] Based on the above technical means, when the tunnel length does not meet the preset length, the environmental information within the visibility range in front of the tunnel exit is obtained when the distance between the vehicle and the tunnel exit meets the preset conditions in real time, so as to avoid unnecessary energy consumption.

[0021] Furthermore, before controlling the windshield wipers of the current vehicle to perform corresponding actions based on the windshield wiper operating parameters, the method further includes:

[0022] Determine whether the second distance between the current vehicle and the tunnel exit is greater than a second preset distance;

[0023] If the second distance is greater than the second preset distance, it is determined that the current vehicle does not meet the wiper control conditions.

[0024] Based on the aforementioned technical means, the windshield wipers will only be controlled to operate according to the wiper operating parameters when the distance between the current vehicle and the tunnel exit meets the preset conditions, thus avoiding unnecessary energy consumption.

[0025] Furthermore, after determining whether a tunnel exists ahead of the current vehicle, the process also includes:

[0026] If the tunnel does not exist, the step of determining whether a tunnel exists in front of the current vehicle is repeated.

[0027] Based on the aforementioned technical means, by determining in real time whether there is a tunnel within a certain range in front of the vehicle, it can be ensured that when driving through a tunnel section, the windshield wipers can be turned on in advance before the vehicle exits the tunnel, thereby improving road traffic safety.

[0028] A windshield wiper control device, comprising:

[0029] The judgment module is used to determine whether there is a tunnel ahead of the current vehicle;

[0030] The determination module is used to obtain the length of the tunnel and the weather information of the current vehicle's location when there is a tunnel in front of the current vehicle, and determine the windshield wiper operating parameters of the current vehicle based on the length and the weather information; and the control module is used to control the windshield wipers of the current vehicle to perform corresponding actions based on the windshield wiper operating parameters.

[0031] Furthermore, the determining module includes:

[0032] The judging unit is used to judge whether the length is less than or equal to a first preset length;

[0033] The acquisition unit is used to acquire environmental information in front of the tunnel exit that meets the preset visibility requirements when the length is less than or equal to the first preset length.

[0034] The determining unit is used to determine the windshield wiper operating parameters of the current vehicle from a preset windshield wiper control parameter table based on the environmental information and the weather information.

[0035] Furthermore, after determining whether the length is less than or equal to the first preset length, the determining unit is further configured to:

[0036] When the length is greater than the first preset length, the first distance between the current vehicle and the tunnel exit is obtained;

[0037] When the first distance is less than or equal to the first preset distance, the step of obtaining environmental information in front of the tunnel exit that meets the preset visibility requirements is executed.

[0038] Furthermore, before controlling the windshield wipers of the current vehicle to perform corresponding actions based on the wiper operating parameters, the control module is also used to:

[0039] Determine whether the second distance between the current vehicle and the tunnel exit is greater than a second preset distance;

[0040] If the second distance is greater than the second preset distance, it is determined that the current vehicle does not meet the wiper control conditions.

[0041] Furthermore, after determining whether a tunnel exists ahead of the current vehicle, the determination module is also used to:

[0042] If the tunnel does not exist, the step of determining whether a tunnel exists in front of the current vehicle is repeated.

[0043] A vehicle includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor executing the program to implement the windshield wiper control method as described in the above embodiments.

[0044] A computer-readable storage medium having a computer program stored thereon, the program being executed by a processor to implement the windshield wiper control method as described in the above embodiments.

[0045] The beneficial effects of this invention are:

[0046] Before a vehicle exits a tunnel, the system intelligently selects the wiper mode and activates the wipers in advance based on weather and environmental information provided by the vehicle's onboard unit. This solves the problem of traffic accidents caused by wipers not activating in time when exiting a tunnel, thus improving road traffic safety. Attached Figure Description

[0053] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0054] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0055] Specifically, Figure 1 This is a flowchart of a windshield wiper control method provided in an embodiment of the present invention.

[0056] For example, such as Figure 1 As shown, the windshield wiper control method includes the following steps:

[0057] In step S101, it is determined whether there is a tunnel in front of the current vehicle.

[0058] It is understood that, in embodiments of the present invention, the presence of a tunnel within a certain distance (e.g., 200m) ahead of the road can be determined by the map navigation system on the vehicle-mounted terminal, or by the navigation software of a mobile terminal such as a mobile phone.

[0059] In step S102, if there is a tunnel in front of the current vehicle, the length of the tunnel and the weather information of the current vehicle's location are obtained, and the windshield wiper operating parameters of the current vehicle are determined based on the length and weather information.

[0060] In other words, when the map navigation shows that there is a tunnel ahead of the vehicle, the length of the tunnel is obtained based on the map navigation, and the weather information of the current vehicle location is obtained based on the weather application software. The weather information includes, but is not limited to, rainfall and visibility. The windshield wiper operating parameters of the current vehicle are then determined based on the tunnel length and the weather information.

[0061] The following details how to determine the windshield wiper operating parameters for a vehicle based on the tunnel length and weather information.

[0062] As one possible implementation, in some embodiments, the windshield wiper operating parameters of the current vehicle are determined based on length and weather information, including: determining whether the length is less than or equal to a first preset length; if the length is less than or equal to the first preset length, obtaining environmental information indicating that the visibility in front of the tunnel exit meets preset visibility requirements; and determining the windshield wiper operating parameters of the current vehicle from a preset windshield wiper control parameter table based on the environmental information and weather information.

[0063] The first preset length can be predetermined by researchers in the field, obtained through a limited number of experiments, or derived from a limited number of computer simulations; no specific limitation is made here. Preferably, in this embodiment of the invention, the first preset length is set to 200m.

[0064] Specifically, when determining the current vehicle's windshield wiper operating parameters based on length and weather information, the system first checks whether the tunnel length is less than or equal to a first preset length (e.g., 200m). If the tunnel length is less than or equal to the first preset length, it immediately acquires environmental information indicating that the visibility requirements (i.e., within the visibility range) are met ahead of the tunnel exit. Environmental information refers to the density of obstacles on both sides of the road ahead of the tunnel exit (obstacles include trees, mountains, and other objects that may affect visibility), including open or dense areas. Open environmental information means that after the current vehicle exits the tunnel, the visibility on both sides of the road is open, without trees, mountains, etc.; dense environmental information means that after the current vehicle exits the tunnel, there are mountains, trees, etc. on both sides of the road. The acquired environmental and weather information is converted into CAN signals, where an open signal is defined as 0x1 and a dense signal is defined as 0x2. The environmental information (0x1 or 0x2) and weather information (rainfall and visibility) are uniformly sent to the intelligent cockpit domain controller in the form of CAN signals. The intelligent cockpit pre-controller, based on the environmental and weather information, looks up and determines the current vehicle's windshield wiper operating parameters from the preset windshield wiper control parameter table.

[0065] The wiper operating parameters include the wiping speed (high speed or low speed) and wiping range (full range or half range). The preset wiper control parameter table can be obtained by training a large amount of data through relevant technical means. To avoid redundancy, it will not be elaborated here.

[0066] Furthermore, in some other embodiments, after determining whether the length is less than or equal to a first preset length, the method further includes: if the length is greater than the first preset length, obtaining a first distance between the current vehicle and the tunnel exit; if the first distance is less than or equal to the first preset distance, performing the step of obtaining environmental information that meets the preset visibility requirements in front of the tunnel exit.

[0067] The first preset distance can be predetermined by researchers in the field, obtained through a limited number of experiments, or obtained through a limited number of computer simulations; no specific limitation is made here. Preferably, in this embodiment of the invention, the first preset distance is set to 200m.

[0068] It is understandable that when it is determined that the length of the tunnel is greater than the first preset length, it is not necessary to immediately obtain environmental information that meets the preset visibility requirements in front of the tunnel exit. Instead, the first distance between the current vehicle and the tunnel exit should be obtained in real time until the first distance is less than or equal to the first preset distance (e.g., 200m), that is, when the current vehicle has traveled to a distance of 200m from the tunnel exit, then the environmental information that meets the preset visibility requirements in front of the tunnel exit can be obtained.

[0069] In step S103, the windshield wipers of the current vehicle are controlled to perform corresponding actions according to the wiper operating parameters.

[0070] In other words, such as Figure 2 As shown in this embodiment of the invention, after the intelligent cockpit domain controller determines the current vehicle's windshield wiper operating parameters based on the tunnel length and weather information, it can send the determined windshield wiper operating parameters (wiping speed and wiping range) to the vehicle domain controller via ICAN (Industry Controller Area Network). After receiving the ICAN signal, the vehicle domain controller then sends the signal to BCAN (Body Controller Area Network) via GW (Gateway), and sends it to the body domain controller via BCAN. The body domain controller forwards the received BCAN signal to BSCAN (Body Subsidiary Controller Area Network). After receiving the signal, the BSCAN of the body intranet sends the determined windshield wiper operating parameters to the wiper controller to control the windshield wipers to perform corresponding actions.

[0071] In addition, in some embodiments, before controlling the windshield wipers of the current vehicle to perform corresponding actions according to the wiper operating parameters, the method further includes: determining whether the second distance between the current vehicle and the tunnel exit is greater than a second preset distance; if the second distance is greater than the second preset distance, it is determined that the current vehicle does not meet the windshield wiper control conditions.

[0072] The second preset distance can be predetermined by researchers in the field, obtained through a limited number of experiments, or derived from a limited number of computer simulations; no specific limitation is made here. Preferably, in this embodiment of the invention, the second preset distance is set to 20m.

[0073] It should be noted that before the Body Domain Controller forwards the received BCAN signal to the Body Internal Network BSCAN, based on the real-time positioning of the current vehicle, it is necessary to determine whether the second distance between the current vehicle and the tunnel exit is greater than a second preset distance (e.g., 20m). If the second distance is greater than the second preset distance, it is determined that the current vehicle does not meet the wiper control conditions, that is, the Body Domain Controller does not need to forward the received BCAN signal to the Body Internal Network BSCAN. Conversely, if the second distance is less than or equal to the second preset distance, it is determined that the current vehicle meets the wiper control conditions, that is, the Body Domain Controller can forward the BCAN signal to the Body Internal Network BSCAN through the BDC (Body Domain Controller).

[0074] Furthermore, in some other embodiments, after determining whether there is a tunnel in front of the current vehicle, the method further includes: if there is no tunnel, then re-execute the step of determining whether there is a tunnel in front of the current vehicle.

[0075] Understandably, if it is determined that there is no tunnel within a certain distance in front of the current vehicle, the navigation system can continuously determine whether there is a tunnel in front of the current vehicle based on the real-time positioning until it shows that there is a tunnel in front of the current vehicle.

[0076] To facilitate those skilled in the art to further understand the wiper control method proposed in the embodiments of the present invention, the following is in conjunction with... Figure 3 To provide further explanation.

[0077] like Figure 3 As shown, Figure 3 A flowchart of a windshield wiper control method according to another embodiment of the present invention is shown, the method comprising the following steps:

[0078] Step S301: Power on the vehicle, enter the destination for this trip, and start map navigation.

[0079] Step S302: Obtain weather information (including rainfall and visibility) provided by the weather application software in real time, and convert the weather information into CAN signals.

[0080] Step S303: Determine in real time whether there is a tunnel 200m ahead of the current vehicle. If yes, proceed to step S304; otherwise, continue with step S303.

[0081] Step S304: Determine if the tunnel length is ≤200m. If yes, proceed to step S305; otherwise, continue to step S306.

[0082] Step S305: Obtain environmental information (open or dense) within the visibility range in front of the tunnel exit and convert it into a CAN signal.

[0083] Step S306: Determine in real time whether the current vehicle is ≤200m from the tunnel exit. If yes, proceed to step S305; otherwise, continue with step S306.

[0084] Step S307: Calculate the current windshield wiper operating parameters of the vehicle based on rainfall, visibility and environmental information, and send them to the ICAN bus via the intelligent cockpit domain controller, and then to the vehicle domain controller via the ICAN bus.

[0085] In step S308, the vehicle domain controller forwards the signal to the BCAN via the GW, and then sends it to the body domain controller via the BCAN.

[0086] Step S309: Determine if the distance between the current vehicle and the tunnel exit is ≤20m. If yes, proceed to step S310; otherwise, continue with step S309.

[0087] In step S310, the vehicle domain controller forwards the received BCAN signal to the vehicle intranet BSCAN.

[0088] In step S311, after receiving the signal, the vehicle's internal network BSCAN sends the determined wiper operating parameters to the wiper controller to control the wipers to perform the corresponding actions.

[0089] According to the windshield wiper control method proposed in this embodiment, when a tunnel is located in front of the vehicle, by acquiring the tunnel length and weather information of the vehicle's current location, the windshield wiper operating parameters can be determined based on the tunnel length and weather information. The windshield wipers are then controlled to perform corresponding actions based on these parameters. Therefore, by controlling the windshield wipers to activate in advance based on weather conditions and the surrounding environment before the vehicle exits the tunnel, the problem of traffic accidents caused by delayed windshield wiper activation when exiting a tunnel is solved, thus improving road traffic safety.

[0090] Next, the control device for a windshield wiper according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0091] Figure 4 This is a block diagram of the windshield wiper control device according to an embodiment of the present invention.

[0094] The determination module 200 is used to acquire the length of the tunnel and the weather information of the current vehicle's location when there is a tunnel in front of the current vehicle, and to determine the operating parameters of the current vehicle's windshield wipers based on the length and weather information; and

[0095] The control module 300 is used to control the windshield wipers of the current vehicle to perform corresponding actions based on the wiper operating parameters.

[0096] Furthermore, in some implementations, module 200 is defined as including:

[0097] The judgment unit is used to determine whether the length is less than or equal to the first preset length;

[0098] The acquisition unit is used to acquire environmental information in front of the tunnel exit that meets the preset visibility requirements when the length is less than or equal to the first preset length.

[0099] The determining unit is used to determine the current windshield wiper operating parameters of the vehicle from a preset windshield wiper control parameter table based on environmental and weather information.

[0100] Furthermore, in some implementations, after determining whether the length is less than or equal to a first preset length, the determining unit is also used to:

[0101] When the length is greater than the first preset length, obtain the first distance between the current vehicle and the tunnel exit;

[0102] When the first distance is less than or equal to the first preset distance, the step of obtaining environmental information in front of the tunnel exit that meets the preset visibility requirements is executed.

[0103] Furthermore, in some implementations, before controlling the windshield wipers of the current vehicle to perform corresponding actions based on the wiper operating parameters, the control module 300 is also used for:

[0104] Determine whether the current distance between the vehicle and the tunnel exit is greater than a second preset distance;

[0105] If the second distance is greater than the second preset distance, it is determined that the current vehicle does not meet the wiper control conditions.

[0106] Furthermore, in some implementations, after determining whether a tunnel exists ahead of the current vehicle, the determination module 100 is also used for:

[0107] If no tunnel exists, the step of determining whether a tunnel exists in front of the current vehicle will be repeated.

[0108] It should be noted that the foregoing explanation of the windshield wiper control method embodiment also applies to the windshield wiper control device of this embodiment, and will not be repeated here.

[0109] The windshield wiper control device proposed in this embodiment of the invention, when there is a tunnel ahead of the vehicle, obtains the tunnel length and weather information of the vehicle's current location, and determines the windshield wiper operating parameters based on the tunnel length and weather information. The device then controls the windshield wipers to perform corresponding actions based on these parameters. Therefore, by controlling the windshield wipers to activate in advance based on weather conditions and the surrounding environment before the vehicle exits the tunnel, the problem of traffic accidents caused by delayed windshield wiper activation when exiting a tunnel is solved, thus improving road traffic safety.
