Abstract
A method for testing a vehicle-to-X communication module by means of a diagnostic device as well as an associated vehicle-to-X communication module and an associated diagnostic device. During a test mode messages are exchanged between the vehicle-to-X communication module and the diagnostic device, and evaluated in order to detect errors.
Claims17
A method for testing a vehicle-to-X communication module comprising:
- placing the vehicle-to-X communication module in a test mode;
- emitting a plurality of test messages from the vehicle-to-X communication module while in the test mode, test messages of the plurality of messages transmitted with differing power;
- receiving the test messages with a diagnostic device;
- analyzing the received test messages with the diagnostic device by:
- measuring power associated with the received test messages, and
- generating transmit spectral masks based on the received test messages;
- and
- detecting errors of the vehicle-to-X communication module based on the analyzed received test messages, wherein the errors include:
- power regulation error detected based on the measured power associated with the received test messages, and
- radio chip error detected based on a function of the transmit spectral masks.
