PORTABLE DEVICE FOR CHANGING OPERATING PARAMETER VALUES AND/OR FIRMWARE OF ELECTRONIC CONTROL UNITS OF MOTOR VEHICLES

摘要

Some embodiments provide a portable device for modifying operating parameter values and/or firmware of electronic control apparatuses of motor vehicles including storage means, processor means connected to the storage means and adapted to read out firmware components and/or operating parameter values from the storage means, and interface means connected to the processor means and adapted to be releasably connected to the communication terminal of the communication bus. The processor means comprises translation means, by means of which the processor means is able to transmit, receive and interpret data, and is adapted to automatically establish a communication connection, to carry out a survey of the control apparatuses as well as of the communication protocols used by them, and to transmit, for each recognized control apparatus, for which firmware components and/or operating parameter values are stored in the storage means, programming commands and data.
