Automotive multiple memory selector apparatus
First Claim
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 with a predetermined operable design for operation of said vehicle, said elements of said system 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 design of said system in which said electronic control unit is employed, said universal module for permitting selection of an additional operational protocol not originally included within said fixed system design, said universal module comprising;
at least one preprogrammed memory for storing said additional program for use in controlling operation of said vehicle in a distinguishable protocol in addition to that provided by said originally provided program and in lieu of control provided by said originally provided program; and
a control coupled only to said preprogrammed memory for selectively communicating said preprogrammed memory to said electronic control unit, operation of said vehicle being changed by said control while said vehicle is in normal operation and thereafter becomes controlled according to said additional program in said preprogrammed memory in lieu of said originally provided program.

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 automotive computer through the operator interactive control.

6. 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 at least one originally provided programmed mode for operating said engine and at least one additional programmed mode; 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 a control coupled to said bus to select said at least one additional programmed mode from said plurality of memories, said additional programmed mode not being originally included in said fixed system as originally manufactured, whereby engine operation is made responsive to said control. - View Dependent Claims (7, 8, 9, 10)

11. 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 at least one originally provided program, said originally provided program for use in controlling said operating performance of said engine; and a bus; wherein said computer and memory are combined in a fixed system with said bus; an universal control means coupled to said bus of said fixed system for providing at least one additional program and for allowing selection of at least one additional program not included as said originally provided program stored within said memory, said selection through said control means designating one of said originally provided program and said at least one additional program for use in controlling said engine. - View Dependent Claims (12)
