Abstract

The ability of an automotive computer for controlling an engine is enhanced by allowing the automotive computer to be controlled by an arbitrarily selected one of a plurality of engine control programs according to arbitrary driver discretion. The bus connecting the computer and memory of a conventional automotive computer is connected to a computer controlled operator interactive control module and an expanded memory. The operator interactive control module allows a human operator to select one of a plurality of memories for coupling to the automotive computer to control engine performance. User on-site customization of the engine control program is permitted by allowing direct downloading of an engine control program into the automative computer through the oeprator interactive control.

Claims

1. An improvement in a vehicle having a predetermined combination of operational elements for controlling vehicular operation according to at least one originally provided program, said predetermined combination of operational elements being defined in a fixed system having a bus, said elements of said system design controlled by an electronic control unit according to said originally provided program said improvement comprising:

a universal module coupled to said bus for arbitrarily reconfiguring programmed control of said electronic control unit regardless of the type of design of said system in which said electronic control unit is employed, said universal module for permitting arbitrary selection among a plurality of additional operational protocols not originally included within said fixed system design, said universal module comprising;

a plurality of preprogrammed memories, each of said memories for storing at least one additional program for use in controlling operation of said vehicle in a distinguishable protocol in addition to those provided by said originally provided program and in lieu of control provided by said originally provided program; and

an interactive control, said interactive control being coupled to said plurality of preprogrammed memories only for selectively communicating one of said plurality of preprogrammed memories to said electronic control unit, operation of said vehicle being changed by said interactive control while said vehicle is in transit and being controlled according to said additional program in said selected preprogrammed memory in lieu of said originally provided program,

whereby said vehicle is caused to operate in a selected protocol according to the arbitrary driver decision from among a plurality of alternatives available in said plurality of preprogrammed memories.

2. The improvement of claim 1 wherein said interactive control comprises means for sensing a plurality of operating conditions, said selected protocol causing said vehicle to operate in a manner consistent with said sensed operating conditions according to said selected protocol.

3. The improvement of claim 1 wherein said operator interactive control comprises means for selectively operating said vehicle without selection of one of said plurality of memories.

4. The improvement of claim 1 wherein said operative interactive control comprises means for controlling said vehicle according to directly entered instructions.

5. The improvement of claim 4 wherein said vehicle includes an engine and wherein said programs stored within said plurality of memories are operating parameters for engine performance.

6. The improvement of claim 1 wherein said operator interactive control comprises a user computer for generating a plurality of memory enable signals and a manual control switch means for allowing manual selection of one of said plurality of memory enable signals, said selected memory enable signal being coupled to said plurality of memories for selecting one of said memories for operation of said vehicle.

7. The improvement of claim 1 wherein said vehicle includes an engine and wherein said programs stored within said plurality of memories are operating parameters for engine performance.

8. The improvement of claim 1 wherein said operator interactive control comprises a user computer for generating a plurality of memory enable signals and a manual control switch means for allowing manual selection of one of said plurality of memory enable signals, said selected memory enable signal being coupled to said plurality of memories for selecting one of said memories for operation of said vehicle.

9. An improved automotive computer for controlling engine performance comprising:

a first computer for providing control signals to said engine, said control signals comprising engine operating parameters;

a plurality of memories coupled to said first computer for providing a plurality of originally provided programmed modes for operating said engine; and

wherein said first computer and plurality of memories are combined to provide a fixed system of control to said engine, said fixed system having a bus coupling said first computer and plurality of memories and having an originally provided fixed selection of programmed modes for operating said engine;

an user-controlled, interactive control coupled to said bus to arbitrarily select one of an additional plurality of programmed modes from said plurality of memories for operating said engine, said selected one of said additional plurality of programmed modes not being originally included in said plurality of memories, said memory having said additional programmed modes being coupled to said first computer to control the operation of said engine during actual transit according to arbitrary human selection among said plurality of programmed modes corresponding to said plurality of memories,

whereby engine operation is made driver responsive.

10. The improved automotive computer control system of claim 9 wherein said interactive control comprises a second computer coupled to said plurality of memories and first computer, said second computer for selectively generating a plurality of memory select commands, said interactive control further comprising a manual control means for allowing said human operator to arbitrarily select one of said memory select commands for coupling to said plurality of memories.

11. The improved automotive computer control system of claim 10 further comprising a plurality of sensors coupled to said second computer for communication to said first computer according to said arbitrarily selected one of said modes corresponding to a selected one of said memories.

12. The improved automotive computer control system of claim 10 further comprising input means for loading user provided operating parameters into said second computer for communication to said first computer for control of said engine.

13. An automotive computer control system for an engine to control engine performance comprising:

a computer coupled to said engine operative to control operating performance of said engine;

a memory coupled to said computer for storing a plurality of originally provided programs, each of said originally provided programs for use in controlling said operating performance of said engine; and

wherein said computer and memory are combined in a fixed system design with a bus;

an universal user-controlled, interactive control means coupled to said bus of said fixed system design for allowing arbitrary driver selection of at least one additional program not included as one of said originally provided programs stored within said memory, said selection through said interactive control means designating one of said plurality of originally provided and said at least one additional program for use in controlling said engine during actual transit as may be arbitrarily determined.

14. The automotive computer control system of claim 13 further comprising means for controlling said computer according to a user provided program for said engine control program.
