Apparatus and method for reading adaptive values out of motor vehicle control devices
First Claim
1. A device for reading out adaptation values of self-adapting functions from a motor vehicle control unit to an external readout unit, the device comprising:
- a motor vehicle control unit;
an external readout unit; and
a communication interface between the external readout unit and the motor vehicle control unit,wherein the motor vehicle control unit comprisesa nonvolatile memory for storing adapted parameters or parameter sets of the self-adapting functions;
a receiver configured to receive at least one test value set transmitted from the external readout unit;
a calculation unit configured to calculate at least one adaptation value as a function of the at least one test value set and the adapted parameters or parameter sets; and
a transmitter configured to transmit the at least one calculated adaptation value to the external readout unit.

Abstract
A device and a method for reading out adaptation values of self-adapting functions from a motor vehicle control unit to an external readout unit are provided. The device consists of a motor vehicle control unit, an external readout unit, and a communication interface between the external readout unit and the motor vehicle control unit, the motor vehicle control unit including a nonvolatile memory for storing adapted parameters or parameter sets of the self-adapting functions. The motor vehicle control unit additionally includes a receiver for receiving at least one test value set transmitted by the external readout unit, a calculation unit for calculating at least one adaptation value as a function of the test value set and the adapted parameters or parameter sets, and a transmitter for transmitting the at least one calculated adaptation value to the external readout unit.
