Abstract
A multiple state automotive data storage and analysis procedure in which vehicle operating parameters are continuously logged in a first state while monitoring the vehicle operating condition for occurrence of any of a predetermined set of trigger conditions. Upon occurrence of any of the predetermined set of trigger conditions, logging operations are suspended and confirmation of occurrence of any of a predetermined set of storage conditions occurs in a second state. If such occurrence is confirmed, a third state is entered in which the logged parameter values are transferred to more permanent memory devices for off-line analysis thereof. If such occurrence is not confirmed, operations of the first state are resumed.
