Abstract

A method for calibrating a sensor of a vehicle is provided. In this method, a sensor measured value that includes a measuring position and a measurement time is received by a data processing unit. Based on the measuring position and the measurement time, the sensor measured value is assigned to at least one reference measured value, which has been ascertained with a reference sensor of a reference vehicle at a reference position and at a reference measurement time, if the measurement time of the sensor measured value and the reference measurement time deviate from one another by a maximum of 30 minutes. In addition, at least one reference calibration value of the reference sensor is communicated to the vehicle and/or provided to the vehicle, so that an instantaneous calibration value of the sensor may be adapted based on the reference calibration value.
