Sensor i.e. hydraulic pressure sensor, testing or calibrating method for motor vehicle, involves evaluating sensor signals produced from sensor as response to test signals

摘要

The method involves stimulating sensors (140) i.e. hydraulic pressure sensor, by transmitting test signals to an actuator (130) i.e. hydraulic pump, which influences measured variable e.g. longitudinal acceleration, related to a motor vehicle. Sensor signals produced from the sensor are evaluated as a response to the test signals. The evaluation is performed based on the sensor signals expected corresponding to the test signals. Calibration of the sensor is performed based on the test signals and the corresponding sensor signals. Independent claims are also included for the following: (1) a computer program product with program code unit for execution of a method for testing or calibrating a sensor (2) a system for testing or calibrating a sensor at a motor vehicle.
