Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
In one embodiment, as shown in fig. 1, an automatic wiper control method is provided, which includes the following steps S10-S40.
And S10, acquiring weather information containing a signal source position from an external signal source through the vehicle-mounted unit.
Understandably, the On Board Unit (OBU) may be a communication device that communicates with a Road Side Unit (RSU) by using a V2X (vehicle to electronic) communication technology. The external signal source refers to a precipitation monitoring source from the outside of the automobile, such as a precipitation sensor (or rainfall sensor) which can be public or collected by a monitoring station set by a weather bureau. The weather information may be a separate complete message (containing only fields relating to weather information) or may be part of a message. The weather information includes at least two fields, one is precipitation (including snowfall) and the other is a signal source location. The position of the signal source can be represented by latitude and longitude, and can also be represented by a doorplate address.
And S20, judging whether the position of the vehicle is in the effective influence area of the position of the signal source.
It is understood that a GNSS (Global Navigation Satellite System) positioning module may be disposed on the vehicle. The vehicle's own position may be obtained by a micro-processing unit (MCU) of the vehicle from the GNSS module. The effective influence area can be set according to actual needs. In some examples, the effective area of influence may be an area that is less than a preset distance threshold from the location of the signal source, or an area that is mapped based on weather conditions in the area where the external signal source is located. Here, the preset distance may be set according to actual needs. Whether the vehicle position is within the effective influence region of the signal source position may be determined by an existing position point identification method (for example, a point tracing method, in which an effective influence region is set to a specific color and identification is performed by color), or a polygon method, in which a ray is taken with the vehicle position as an end point and identification is performed by the number of effective intersections of the ray and the effective influence region (polygon) (odd or even).
And S30, if the position of the vehicle is in the effective influence area of the signal source position, generating a wiper control instruction according to the weather information.
Understandably, if the position of the vehicle is in the effective influence area of the signal source position, the wiper control instruction is generated according to the weather information. Different weather information corresponds to different wiper control instructions. For example, if the current weather information indicates a large amount of rain, the wiper control command includes: and starting a wiper command, and setting the working frequency of the wiper to be high speed.
And if the position of the vehicle is not in the effective influence area of the signal source position, the wiper control instruction cannot be generated according to the weather information. At this time, the operating state of the wiper blade may be manually controlled by a user.
And S40, sending the wiper control instruction to a wiper so as to adjust the working state of the wiper according to the wiper control instruction.
Understandably, the wiper control command may be transmitted to the wiper. After the wiper receives the wiper control instruction, the electrifying state of a wiper motor (a driving part of the wiper) is changed according to the wiper control instruction, and then the working state of the wiper is adjusted. Different wiper control instructions correspond to different working states of the wiper. For example, if the wiper control command is a close command, the wiper enters a close state.
As shown in fig. 2, in one example, the wiper control command may be generated by a Micro Control Unit (MCU) provided in a V-BOX (a kind of smart car terminal). And then sending the wiper Control instruction to a Body Controller (BCM), sending the wiper Control instruction to a wiper motor (a driving part of the wiper) by the Body controller, and changing the power-on state of the wiper motor according to the wiper Control instruction so as to adjust the working state of the wiper. The external signal source in fig. 2 may refer to a rain sensor or a weather monitoring station and the transmission intermediary may refer to a roadside unit.
As shown in fig. 3, in another example, the wiper control instruction may be generated by a Micro Control Unit (MCU) provided in the vehicle body controller. The vehicle body controller sends the wiper control instruction to a wiper motor (a driving part of the wiper), and the power-on state of the wiper motor is changed according to the wiper control instruction, so that the working state of the wiper is adjusted. The external signal source in fig. 3 may refer to a rain sensor or a weather monitoring station and the transmission intermediary may refer to a roadside unit.
In steps S10-S40, weather information including a signal source position from an external signal source is acquired through the vehicle-mounted unit, and the weather information can be conveniently acquired through V2X communication. And judging whether the position of the vehicle is in the effective influence area of the position of the signal source so as to determine the availability of the weather information. And if the position of the vehicle is in the effective influence area of the position of the signal source, generating a wiper control instruction according to the weather information, wherein the wiper control instruction can realize the automatic control of the wiper. And sending the wiper control instruction to the wiper so as to adjust the working state of the wiper according to the wiper control instruction, thereby realizing the automatic control of the wiper. The embodiment can realize the automatic control of the windscreen wiper and reduce the installation cost of the rainfall sensor.
Optionally, step S10, that is, the acquiring weather information including a signal source location from an external signal source includes:
s101, the external signal source sends the collected weather information to a road side unit;
s102, the road side unit sends the weather information to a V2X module of the vehicle-mounted unit.
Understandably, the external signal source can send the collected weather information to the adjacent road side unit. A Road Side Unit (RSU) is a communication device that is disposed On the road side and can communicate with a V2X module of an On Board Unit (OBU). The roadside unit may send a message with a particular message structure to the V2X module. The message is provided with a weather information field. For example, the messages as in table 1 may be generated with reference to "collaborative intelligent transportation system automotive communication system application layer and application data interaction standard" (TCSAE 53-2017).
Table 1 messages containing weather information fields
In table 1, each cell represents a field in the message. Wherein the "rainfall data" and the "signal source position information" belong to the weather information field.
Optionally, the external signal source comprises a precipitation sensor and/or a weather monitoring station associated with the roadside unit.
Understandably, precipitation sensors may be provided on the roadside of some key roads. Each precipitation sensor is connected with the road side unit in the peripheral designated range, and the real-time weather information (including precipitation data) monitored by the precipitation sensor can be sent to the road side unit.
In other cases, the weather monitoring station is connected with the roadside units within the peripheral designated range, and can send the real-time weather information (including precipitation data) monitored by the weather monitoring station to the roadside units.
Optionally, the external signal source includes a signal source vehicle that establishes a communication connection with a vehicle, and the signal source vehicle is equipped with a rainfall sensor.
Understandably, the external signal source may refer to a signal source vehicle mounted with a rainfall sensor. The signal source vehicle can establish a communication connection with the current vehicle. Then, the signal source vehicle transmits the weather information to the current vehicle in a V2X communication manner. In some cases, such as traveling of a fleet, as long as one signal source vehicle exists, automatic control of the wipers of all vehicles in the whole fleet can be realized.
Optionally, step S20, before the step of determining whether the position of the vehicle is within the effective influence area of the signal source position, further includes:
s21, obtaining regional weather data of a region where the signal source position is located;
and S22, setting the effective influence area according to the area weather data.
Understandably, the area where the signal source is located can be set according to actual needs. In one example, the area in which the signal source is located may be a street or a town in which the signal source is located. Regional weather data can be an overall weather profile for the region in which the source location is located, including but not limited to precipitation (including snowfall), wind direction, wind speed, and the like. Regional weather data can also be weather information for multiple monitoring points in the region of the signal source location. The effective range of the weather information received by the vehicle can be evaluated according to the weather information of the monitoring points, and then the effective influence area is determined according to the effective range. Within the effective area of influence, the real-time precipitation amount of all location points can be considered equal.
Optionally, the effective influence area of the signal source position includes an area where a distance from the signal source position is smaller than a preset distance threshold, where the preset distance threshold includes 100m to 2000m.
Understandably, the effective influence area of the signal source position can be set as an area with the signal source position as the center of a circle and the preset distance threshold as the radius. Within the effective area of influence, the real-time precipitation at all location points can be considered equal. The preset distance threshold value can be set according to actual needs. For example, the preset distance threshold may be 100m to 2000m.
Optionally, the weather information includes precipitation;

s301, if the precipitation is smaller than a first precipitation threshold value, the wiper control instruction is a closing instruction;
s302, if the precipitation is greater than or equal to the first precipitation threshold and smaller than a second precipitation threshold, the wiper control instruction is a starting instruction, and the working frequency of the wiper is low speed;
and S303, if the precipitation is greater than the second precipitation threshold value, the wiper control instruction is a starting instruction, and the working frequency of the wiper is high speed.
Understandably, the first precipitation threshold and the second precipitation threshold may be set according to actual needs. The first precipitation threshold and the second precipitation threshold may be selected differently for different regions. And if the precipitation is smaller than the first precipitation threshold value, the wiper control instruction is a closing instruction, and at the moment, the wiper is in a closing state. If the precipitation is greater than or equal to the first precipitation threshold and smaller than the second precipitation threshold, the wiper control instruction is a starting instruction, the working frequency of the wiper is low speed, and at the moment, the wiper is in a low-speed running state.
