Abstract

The invention relates to a method and system for automatically calibrating a rainfall sensor of a vehicle based on a vehicular networking communication technology as well as a vehicle. The method comprises the steps of firstly sharing data of the rainfall sensor by virtue of the vehicular networking communication technology and then performing fusion calculation on the data of the rainfall sensorof the vehicle and data of rainfall sensors of vehicles around to obtain an optimal value, so that normal execution of functions of the rainfall sensor of the vehicle is guaranteed and the functions still can be normally realized even if the sensor is in fault. The system comprises the rainfall sensor of the vehicle, a data sharing module, a data screening calculation module, a data fitting moduleand a control and execution module. The method provided by the invention obtains multiple groups of optimal values by performing the fusion calculation on data of multiple rainfall sensors and then performs fitting operation, so that operation parameters of the rainfall sensor of the vehicle are calibrated, an error of the rainfall sensor of the vehicle is reduced and the probability of occurrence of misinformation and failure in report is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of automotive electrical appliances and the technical field of the Internet of Vehicles, and more specifically, to a method for automatically calibrating a vehicle rain sensor based on the communication technology of the Internet of Vehicles. Background technique [0002] As the wave of intelligence unfolds in the automotive industry, more and more sensors are used in the automotive manufacturing industry. The rain sensor is one of them. It is located at the rear of the front windshield. It can automatically adjust the speed of the wiper according to the size of the rain falling on the glass. Since the driver's vision is greatly disturbed when driving in rainy and snowy days, it can ensure that the driver has a good vision, thereby greatly improving the convenience and safety of driving in rainy days. [0003] In the existing technology, an optical sensor is usually installed on the vehicle, and the...
