1. A method comprising:
- measuring a sound, a vibration, or both produced by one or more vehicle components of a vehicle;
measuring one or more vehicle parameters during operation of a vehicle, the vehicle parameters pertaining to operation of an engine of the vehicle, a requested acceleration for the vehicle, or both;
comparing the measured sound, vibration or both with an expected sound, vibration, or both for the one or more vehicle components that would be expected for the vehicle as it is operated given the vehicle parameters pertaining to operation of an engine of the vehicle, a requested acceleration for the vehicle, or both, generating a comparison; and
diagnosing a vehicle system or device using the comparison of the measured sound, vibration, or both with the expected sound, vibration, or both for the one or more vehicle components that would be expected for the vehicle as it is operated given the vehicle parameters pertaining to operation of an engine of the vehicle, a requested acceleration for the vehicle, or both.

11. A method comprising:
-
operating one or more test vehicles under a plurality of conditions, each of the plurality of conditions representing a different combination of values of different vehicle parameters during operation of test vehicles, the vehicle parameters pertaining, for each test vehicle, to operation of an engine of the test vehicle, a requested acceleration for the test vehicle, or both; measuring a corresponding powertrain-related sound, vibration, or both for each of the plurality of conditions for the test vehicles; and storing, in memory, information pertaining to each of the plurality of conditions along with the corresponding powertrain-related sound, vibration, or both for each of the plurality of conditions, for subsequent use in diagnosing one or more vehicle systems or devices for a different vehicle by comparing engine-related sounds, vibrations, or both in a subsequent drive cycle of the different vehicle with the stored information when the different vehicle is driven under similar conditions for the parameters of the different vehicle pertaining to operation of an engine of the different vehicle, a requested acceleration for the different vehicle, or both.
