Vehicle data system and method for determining relevant or transmission-suitable vehicle data from an environment-sensing sensor

A vehicle data system operable during vehicle operation, comprising:

• an environment-sensing sensor configured to acquire input data representing an environment of a vehicle;
• and
• a data processor operatively coupled to the environment-sensing sensor, the data processor comprising:
• an environment detection system configured to:
• receive the input data from the environment-sensing sensor,
• evaluate the input data using a first trained artificial neural network (ANN), and
• output environment detection data to a controller configured to perform assisted or automated driving of the vehicle;
• and
• a monitor system configured to:
• receive the same input data from the environment-sensing sensor,
• evaluate the input data using a second trained ANN different from the first trained ANN,
• output reconstruction data,
• establish a deviation between the reconstruction data and the input data, and
• in response to the deviation exceeding a threshold value during vehicle operation, transmit the input data to a separate data unit, wherein the separate data unit is configured to store the transmitted input data.
