Problems solved by technology

[0002] At present, the windshield wiper of a vehicle is one of the most frequently used accessories by the driver during the driving process of the vehicle: an accessory that is used so frequently does not provide any auxiliary information to people because of the specificity of its use conditions, and the user When driving a vehicle, the wiper is activated based on the user's active trigger. When encountering rain, it is likely that the delay in the manual trigger by the user will cause the precipitation to cover the front windshield of the car, and it is easy to see the road conditions clearly, or The oncoming vehicle did not see the approaching vehicle, causing an accident

Embodiment 1

[0080] According to an embodiment of the present invention, an embodiment of a vehicle headlight control method is provided. It should be noted that the steps shown in the flow charts of the drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0081] Embodiment 1 of the present invention provides a method for determining precipitation areas based on wiper status, such as figure 1 As shown, the following steps S101-S106 may be included:

[0082] S101: Divide the map data into regions to obtain each geographic region unit;

[0083] In this embodiment, the geographical area unit is obtained by dividing the map data into areas. It may be that the geographical area unit is set as a square with a side length of 500 meters, and the map data is divided into areas ...

Embodiment 3

[0139] Embodiment 3 of the present invention provides a device 40 for determining a precipitation area based on the wiper state, such as Figure 4 shown, including:

[0140] The geographical area unit division module 41 is used to divide the map data into areas to obtain each geographical area unit;

[0141] The wiper status acquisition module 42 is used to acquire the status of the wiper of the vehicle in real time, and the current position of the vehicle whose wiper is in working condition;

[0142] The vehicle number determination module 43 is used to determine the number of vehicles with wipers in working state in each geographical area unit according to the matching relationship between the current position of the vehicles with wipers in working state and the geographical area unit;

[0143] The precipitation area unit determination module 44 is configured to determine that the geographic area unit is a precipitation area unit when the number of vehicles in the geographica...

Embodiment 4

[0145] Embodiment 4 of the present invention provides a wiper control device 50 based on the state of the wiper, such as Figure 5 shown, including:

[0146] The precipitation area determination device 40 based on the wiper state;

[0147] The vehicle driving parameter acquisition module 51 is used to acquire the driving parameters of the current vehicle, the driving parameters at least including the driving direction and the driving position of the current vehicle;

[0148] A precipitation area unit identification module 52, configured to identify the precipitation area unit in the current direction of travel of the vehicle based on the travel direction of the current vehicle;

[0149] The distance acquisition module 53 is used to acquire the real-time distance of the precipitation area unit on the driving position of the current vehicle and the direction of travel;

[0150] The control module 54 is configured to control the wiper of the current vehicle to be turned on or o...

Abstract

The invention provides a rainfall area determination method based on a wiper state and a wiper control method. The method comprises the following steps that regional division is carried out on map data to obtain geographic area units; the state of the wiper of a vehicle and the current position of the vehicle when the wiper in the working state are acquired in real time; the number of the vehiclein each geographic area unit when the wiper in the working state is determined according to the matching relation of the current position of the vehicle when the wiper in the working state and the geographic area units; and then a rainfall area unit is determined; the rainfall area unit on the current vehicle traveling direction is further identified through driving parameters of the current vehicle, and when the real-time distance between the driving position of the current vehicle and the rainfall area unit meets a preset distance threshold, and the wiper of the current vehicle is controlledto be started or closed; and the purposes that when entering the environment needing to start the wiper, the wiper of the vehicle can be controlled to be started in advance, and the wiper is automatically controlled are achieved.

Description

technical field [0001] The invention relates to the technical field of area determination and vehicle control, in particular to a method for determining a precipitation area based on the state of a windshield wiper and a method for controlling the windshield wiper. Background technique [0002] At present, the windshield wiper of a vehicle is one of the most frequently used accessories by the driver during the driving process of the vehicle: an accessory that is used so frequently does not provide any auxiliary information to people because of the specificity of its use conditions, and the user When driving a vehicle, the wipers are activated based on the user's active trigger. When encountering rain, it is likely that the precipitation will cover the front windshield due to the delay of the user's manual trigger. It is easy to see the road conditions clearly, or The oncoming vehicle did not see the approaching vehicle, which caused the accident. [0003] Therefore, there i...
