Abstract
The system includes a central memory, in which all programs necessary for controlling/regulating the operational sequences of a vehicle are stored. At the start of the system, the control units load the needed programs into their working memory via indirect memory access. The method provides that, after the system is switched on, the units first identify themselves. After that, by means of the loading programs, the programs are loaded from the central memory into the working memory of each control unit via indirect memory access.
Claims7
A system for controlling/regulating operating sequences of a motor vehicle, comprising:
- controlling/regulating control units, each of the control units having a volatile memory and a non-volatile memory, the non-volatile memories containing a loading program;
- a main control device having a central memory, the central memory storing programs of the control units, providing indirect access of the control units to the central memory;
- and
- connecting elements for providing an identification of an appropriate at least one of the control units, each of the connecting elements coupling a respective one of the control units to a communications system.
A method for starting a system for controlling/regulating operational sequences in a motor vehicle having controlling/regulating control units, each of the control units having a volatile memory and a non-volatile memory containing a loading program, the motor vehicle further having a main control device having a central memory, the method comprising:
- switching on the system;
- identifying the control units;
- starting the loading program in the non-volatile memories of the control units;
- providing an indirect access of the control units to the central memory;
- and
- loading programs into a corresponding volatile memory of the control units.
