DESCRIPTION:
BRIEF SUMMARY
STATE OF THE TECHNOLOGY
The invention is an improvement upon an apparatus for control of technical installations and machines, particularly of combustion engines in motor vehicles.
Such a control scheme is known from German Published Unexamined Application DE-OS 35 43 966 and corresponding U.S. Ser. No. 201,343, BRAUNINGER et al., now U.S. Pat. No. 4,896,263, issued Jan. 23, 1990. It features at least one freely programmable memory and at least one permanently programmed memory. In the permanently programmed memory are stored multiple variants of data records under various retrieval codes, and in the freely programmable memory are stored the various retrieval codes of the data records. If such a control scheme is desired for various purposes, for example for use in a variety of vehicle types, inputting appropriate retrieval codes in the freely programmable memory permits retrieval of appropriately selected data records from the permanently programmed memory. The disadvantage of this approach is that the possible uses of the control device is limited by the number of various data records. It is not possible for the user of the control device to modify the data records easily; rather, swapping out of the control device or at least the freely programmable memory is required.
German Published Unexamined Application DE-OS 34 07 920 and corresponding U.S. Pat. No. 4,677,558, BOHMLER et al., issued Jun. 30, 1987 discloses a control device in which the permanently programmed memory stores the basic program for generation of various control commands and a program for selection of the data required in the calculations. A freely programmable memory stores a specific data record with the associated retrieval code for the machine or vehicle to be controlled. The data are input into the control device, together with the retrieval codes, by the manufacturer. Only he can--if necessary--alter the addresses in the freely programmable memory and add more data.
The disadvantage is that the user of such a control device is initially tied to the data record of the manufacturer, and the alteration possibilities are limited. Furthermore, the assistance of the manufacturer must be enlisted to make changes. Even after alteration of the data and/or addresses, the user again has only one data record available. Thus, the possibilities of use are severely limited.
ADVANTAGES OF THE INVENTION
By contrast, the apparatus and method of the present invention have the advantage that the user himself can freely choose one or multiple data records, and is not tied to the data presupplied by the manufacturer. The manufacturer of the control device merely supplies the functional program, i.e. the calculation program and the program for selection of data. This results in substantially more possibilities of use for such a control device. It is particularly advantageous to be able to recognize faulty memory cells when storing data, the associated retrieval codes and an address pointer. Then the data, retrieval codes, and the address pointer are stored in intact memory cells.
DRAWING
A sample embodiment of the invention will be explained with reference to the drawings, in which:
FIG. 1 is a block diagram of a control device according to the invention; and
FIG. 2 illustrates the structure of the information stored in the control device.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The apparatus and method according to the invention are suitable for controlling an arbitrarily wide range of technological installations and machines. The description focuses only by way of example on the control of a combustion engine of a motor vehicle.
A control scheme of the sort described here involves an electronic engine control with at least a microprocessor, at least one permanently programmed memory, and at least one freely programmable memory. These control devices are built in, during manufacture of a vehicle, at a suitable location. The control devices for various vehicle types and models are identical. They initially contain merely calculation programs,
