Abstract
The description relates to a process and a device for controlling internal combustion engines in motor vehicles with at least one microprocessor. Two data records may be written into a first store. An identification signal may be written into a preferred storage cell of each data record.
Claims30
A method for controlling an internal combustion engine in a motor vehicle having at least one microprocessor, comprising the steps of:
- storing at least two data records in a first memory device, each of the data records having an identifier, including a coded bit pattern for marking an identity of a data record, stored in a same predetermined relative location within each of the data records;
- and
- controlling the internal combustion engine as a function of the data records.
A system for controlling an internal combustion engine in a motor vehicle, comprising:
- a first memory device having at least two data records stored therein,
- each of the data records having an identifier, including a coded bit pattern for marking an identity of a data record, stored in a same predetermined relative location within each of the data records;
- and
- a microprocessor coupled to the first memory device for controlling the internal combustion engine as a function of at least one of the at least two data records.
A method for storing and retrieving data records, for controlling an internal combustion engine comprising the steps of:
- storing at least two data records in a first memory device, each of the data records having an identifier, including a coded bit pattern for marking an identity of a data record, stored in a same predetermined relative location within the data records, each of the data records further having at least one engine control variable stored therein;
- storing a selection value in a second memory device;
- comparing the selection value to the identifier stored in at least one of the data records;
- retrieving the at least one of the data records when the selection value matches the identifier stored in the at least one of the data records;
- and
- controlling the internal combustion engine as a function of the retrieved at least one of the data records.
A method for controlling an internal combustion engine in a motor vehicle having at least one microprocessor, comprising the steps of:
- storing at least two data records in a first memory device, each data record occupying a distinct and contiguous set of memory locations;
- storing an identifier in a same predetermined relative memory location of each data record;
- storing a selection value in a second memory device;
- selecting a matching data record using the selection value and the identifier stored in the predetermined relative memory location of each data record;
- and
- controlling the internal combustion engine as a function of the selected matching data record.
A device for controlling an internal combustion engine in a motor vehicle comprising:
- at least one microprocessor;
- a first memory device for storing at least two data records, each data record occupying a distinct and contiguous set of memory locations and containing a same predetermined relative memory location for storing an identifier;
- a second memory device for storing a selection value;
- the at least one microprocessor being adapted to select a matching data record using the selection value and the identifier stored in the predetermined relative memory location of each data record, and to control the internal combustion engine as a function of the selected matching data record.
