ABSTRACT:
A solid state unit is provided which is intended as an aid in the maintenance and upkeep of a motor vehicle, and which serves as a reminder of the next maintenance mileage point, and the items to be serviced at the next maintenance operation. The unit also serves as a permanent record of the scheduled maintenance that has been performed on the vehicle throughout its lifetime. The unit is intended to be mounted under the dashboard, or at any other convenient location within the vehicle. The unit includes a programmable read-only memory (PROM) in which data is permanently stored representing the mileage at which the next maintenance operations are to be performed, as well as data identifying the items requiring servicing at the next maintenance point. The unit also includes an appropriate display, and solid state logic circuitry which, when activated, causes the mileage at which the next scheduled maintenance is to be performed, as well as the items to be serviced at the next scheduled maintenance point, to be displayed. In addition, the unit may be conditioned to display the last maintenance mileage point, and the items actually serviced at the last maintenance operation. In a preferred embodiment of the invention, the memory also stores as a permanent record data relating to all previous actually performed maintenance operations, and the mileage points at which such operations were performed. In addition, data relating to the identity of the dealer who serviced the vehicle at each maintenance point may be stored in the memory; as well as data relating to the original dealer, the make, model and year, and the serial number of the vehicle.
