In Step S11, environmental information at a vehicle location of the vehicle is acquired. The environmental information at the vehicle location of the vehicle includes environmental temperature. The device may acquire the environmental information using one or more sensors on the vehicle. Alternatively or additionally, the device may acquire the environmental information from an online database based on the vehicle location.
The environmental information at the vehicle location of the vehicle may include, for example, environmental information corresponding to at least one of following time points: a current moment, a future moment at preset time interval from the current moment, a time period where the current moment is located, a time period where the future moment is located, and the like. Here, centigrade degree, for example, may be a measure of the environmental temperature.
In Step S11, the environmental information at the vehicle location of the vehicle may be acquired through a device within the vehicle, or another device outside the vehicle.
For example, acquiring the environmental information at the vehicle location of the vehicle in Step S11 may include: acquiring the environmental information measured by a sensor of the vehicle at the vehicle location; or acquiring the information from a terminal equipment at the vehicle location.
Here, the sensor may be a sensor corresponding to an environmental parameter in the environmental information, set by the vehicle, at the vehicle location. After acquiring the environmental information at the vehicle location of the vehicle, the sensor may send the environmental information at the vehicle location of the vehicle to a device for controlling a windscreen wiper through a wireless or wired connection.
The terminal equipment may be terminal equipment of a passenger of the vehicle. The device for controlling a windscreen wiper may receive the environmental information sent by a mobile terminal in any communication manner of Near Field Communication (NFC), Wireless-Fidelity (WiFi) communication, BlueTooth (BT) communication, a data line and the like.
For example, when the environmental information at the vehicle location of the vehicle includes environmental temperature, the sensor may include a temperature sensor. The temperature sensor may acquire the local environmental temperature at the vehicle location. The terminal equipment may directly measure the environmental temperature, or acquire the environmental temperature and the like from a preset server.
