A process and apparatus for determining maintenance and servicing intervals on motor vehicles which makes it possible to carry out maintenance or servicing work as a function of the states of wear of the operating parameters to be maintained, wherein values corresponding to the particular states of wear of the operating parameters are fed to a computing unit, and by comparison with values filed in its store the computing unit displays a recommendation to carry out the maintenance work when an operating parameter has approached or reached the wear limit. The motor vehicle driver can thus see which driving behavior to adopt in order to achieve as long a maintenance interval as possible, so that he has an incentive to drive economically. Practice of the invention assures that parts are exchanged or renewed only when this is actually necessary.

A method for determining maintenance and service intervals for a vehicle comprising storing a limit value for a vehicle command parameter, sensing an actual value of the command parameter, performing a first comparison of the sensed actual value with the limit value for the vehicle command parameter

A method for determining maintenance and service intervals for a vehicle comprising storing a limit value for a vehicle command parameter, sensing an actual value of the command parameter, performing a first comparison of the sensed actual value with the limit value for the vehicle command parameter, displaying a maintenance alarm when said first comparison step produces a substantial match of the two values, storing a limit value for at least one vehicle operating parameter, storing a maintenance indication threshold value as a fraction of said limit value for said at least one operating parameter, sensing an actual value of the at least one operating parameter, performing a second comparison of the sensed actual value with the maintenance indication theshold value for the at least one operating parameter if the first comparison step produced a substantial match, displaying at least an additional maintenance alarm for said operating parameter when said second comparison step determines that the actual value of said sensed operating parameter exceeds the maintenance indication threshold value. A method of determining maintenance and service intervals in motor vehicles, wherein the driver is given a recommendation by means of a display to perform maintenance or servicing when a value of a guiding parameter, determined to be important for maintenance or servicing, corresponds to a predetermined value of the guiding parameter stored in a memory of a computer, whereby the determined value of this guiding parameter can be changed by other operating parameters, comprising the steps of receiving in a computer memory additional characteristic values for the condition of vehicle parts requiring maintenance as a function of wear, comparing said values with values likewise stored in the memory and corresponding to the wear limits of the vehicle parts in question, generating data representing a load diagram in the computer from additional operating parameters, determining from at least the additional operating parameters whether the vehicle is being operated primarily in the partial load or full load mode, extrapolating a wear-limiting value for each of the vehicle parts from at least a corresponding stored value by means of the data representing the load diagram, and matching the wear-limiting values of the vehicle parts with data representing maintenance or servicing determined by the guiding parameter, when the values and data lie within a fixed range of tolerance of the data.
