Abstract: A method for temperature compensation of a sensor measurement value of a sensor in a vehicle's safety system during vehicle operation, wherein the sensor comprises predetermined temperature compensation data for a predetermined temperature compensation, which are stored in readable fashion in a memory unit of the sensor. The vehicle has an electronic control unit which performs an algorithm for improving the temperature compensation by way of a temperature compensation that is more extensive than the predetermined temperature compensation, and wherein the stored temperature compensation data are made available to the algorithm as a basis for the more extensive temperature compensation.
