Abstract

A control apparatus for an automobile is provided with a system manager, which initiates and manages the operation of units for controlling and operating various devices and accessories installed in the automobile. The system manager is coupled with a card unit, in which a card is inserted. Such a card has an identification code ID of a user and a code indicating that the card is registered in advance. The system manager has a list of codes of cards registered. If a card inserted is confirmed to be correct and valid by the ID and the registration code, the system manager executes a predetermined processing operation and produces a set-up instruction signal. Upon receipt of this set-up instruction signal, operations of the control units for the devices and accessories are initiated.

Claims

1. A control apparatus for an automobile, comprising:

a plurality of operating units each for controlling respective ones of various kinds of automobile control devices and other automobile accessories installed in an automobile, each of said devices and accessories being designed to achieve its own particular function under control of its operating unit or in response to a signal from another operating unit or units;

an information read/write unit for reading/writing a recording medium on which at least information for identifying a valid user of the automobile is recorded; and

a system manager, including a processing unit and a memory coupled with said operating units and said information read/write unit, which identifies a valid user on the basis of the information recorded on the recording medium and brings ones of said operating units for the various kinds of devices and accessories, which are selected in accordance with the result of the user identification, into an operable condition, thereby enabling such functions and characteristics of the automobile as the user desires.

2. A control apparatus according to claim 1, wherein the information recorded in a recording medium includes a code particularly assigned to the recording medium and a list of codes of recording media registered in advance is provided, and wherein when a recording medium is inserted in the information read/write unit, said system manager refers to the code list to judge whether or not the recording medium inserted is a registered one and initiates operations of said controlling units, only if the recording medium is judges to be registered.

3. A control apparatus according to claim 2, wherein said system manager is further provided with means capable of inputting at least code data and the information recorded in a recording medium includes an identification code which is assigned to an individual user using the recording medium, and wherein said system manager initiates operations of said controlling units only if a recording medium inserted is judges to be registered and an identification code inputted by a user is coincident with the identification code recorded in a recording medium inserted in the information read/write unit.

4. A control apparatus according to claim 1, wherein said system manager is provided with means capable of inputting at least code data and the information recorded in a recording medium includes an identification code which is assigned to an individual user using the recording medium, and wherein said system manager initiates operations of said controlling units if an identification code inputted by a user is coincident with the identification code recorded in a recording medium inserted in the information read/write unit.

5. A control apparatus according to claim 4, wherein when a user inserts a recording medium in the information read/write unit and can not input a correct identification code within a predetermined number of times of trying to input the identification code, a code or flag indicating an invalid card is recorded in the recording medium, whereby said system manager can no longer be operated with the recording medium.

6. A control apparatus according to claim 1, wherein a user can select some of said controlling units, which are desired to be used by the user'"'"'s own manipulation in accordance with guidance displayed on a display device by said system manager, and wherein the thus selected controlling units are registered in the memory of said system manager in order to make those control units operable and are recorded by the information read/write unit in the recording medium.

7. A control apparatus according to claim 6, wherein when the user selects the controlling units to be used, the specifications of the selected controlling units can be determined, which are recorded by the information read/write unit in the recording medium together with the selected controlling units.

8. A control apparatus according to claim 7, wherein the registration and change of said controlling units to be used and their specifications are allowed only during a certain condition of the automobile.

9. A control apparatus according to claim 8, wherein the registration and change said controlling units and their specifications, which directly relates to the travel of the automobile, including an engine control unit, a transmission control unit and a power steering unit, is not allowed when the automobile travels.

10. A control apparatus according to claim 9, wherein when the automobile travels, part of the guidances displayed on the display device, which concerns the change of the units and their specifications directly relating to the travel of the automobile, is masked.

11. A control apparatus according to claim 6, wherein the controlling units installed in the automobile includes a disk unit, in which a floppy disk can be inserted, and, when the disk unit is registered in the system manager, the alteration of programs for the devices and accessories can be carried out by the floppy disk.
