A method for manipulating a first function of a control program of an electronic control device, using a second function. The control program is processed using a first calculation kernel of a processor, and the second function is processed by a second calculation kernel during the processing of the control program. The first function assigns a first value to a variable and writes the first value to the storage address of the variable at a first time. The second function assigns a second value to the variable, which value is written to the storage address of the variable at a second time, wherein the second value written by the first function is overwritten. At a third time, the control program reads the second value from the storage address of the variable. A control entity coordinates the times at which the storage address of the variable is accessed.

Method for manipulating a control program of a control device

A method for changing software in a memory of an electronic control unit, wherein each memory address from the overlay memory can be assigned to a memory address in the read-only memory by an assignment information item. During a run time of the control unit, at least a functional part of a bypass routine that is to at least partially replace an original program routine is stored in an address range in the overlay memory, or a jump instruction is stored in the overlay memory as the first part of a bypass routine that refers to a second part of the bypass routine that is stored in an address range accessible to the processor. To activate an overlay functionality the address and/or the address range of the overlay memory are assigned to an address or address range of the program routine to be replaced.

Method for changing the software in the memory of an electronic control unit

A method for processing data of a control unit in a data communication device, which has a first memory area and a second memory area, and is connected to the control unit through an interface. Data from the control unit is transmitted to the data communication device through the interface. A value is stored identically in the first memory area and in the second memory area. The data communication device tests whether a first trigger is present, and if present, storage in the first memory area is discontinued, or the trigger class of the first trigger is tested and storage in the first memory area is discontinued only in the presence of a predefined trigger class. Subsequently, values of the data are read out from the first memory area, whereby values arriving chronologically after the first trigger are stored in the second memory area by the data communication device.

Method for processing data of a control unit in a data communication device

A method is provided for processing data in an influencing device, whereby the influencing device is connected to a vehicle control unit and to a data processing unit. The vehicle control unit and the influencing device are disposed in a motor vehicle or, for example, on a test bench in a laboratory. A first program runs in the vehicle control unit. Data are exchanged according to an XCP protocol and/or a CCP protocol between the data processing unit and the influencing device. The influencing device has a second execution unit, which executes predetermined data processing steps more rapidly than the first execution unit. The data exchanged by the XCP protocol or the CCP protocol are checked for a predetermined criterion and, based on the result of the check, the data are processed either in the first execution unit or in the second execution unit.

Method for processing data in an influencing device

A method for controlling an operating mechanism using a manipulation unit, in which the operating mechanism includes at least one microcontroller, at least one memory with a plurality of memory cells, and at least one debug interface, and the debug interface presents a monitoring functionality for monitoring memory content and using the debug interface a first timepoint of the operating mechanism is detected for writing into a first memory cell and, using the information transmitted by the debug interface for the first timepoint to the manipulation unit, a trigger timepoint results for a processing routine through the manipulation unit (IN) and using the processing routine a second value is written by the manipulation unit using the debug interface for a second timepoint in the first memory cell before the first memory cell is read by the operating mechanism for a third timepoint.

Method for controlling an operating mechanism and a manipulation unit

A method for controlling an operating mechanism using a manipulation unit, in which the operating mechanism includes at least one microcontroller, at least one memory with a plurality of memory cells and at least one first value in a first memory cell and at least one debug interface, and the debug interface exhibits a monitoring functionality for monitoring a program code executed by the operating mechanism and using the debug interface a first pre-set timepoint is detected when processing the program code and, using the information transmitted by the debug interface for the first timepoint to the manipulation unit, a trigger timepoint results for a processing routine through the manipulation unit (IN) and a second value is written using the debug interface by the manipulation unit using the processing routine for a second timepoint in the first memory cell before the first memory cell is read by the operating mechanism for a third timepoint.

A method for influencing a control unit by means of a manipulation unit whereby the control unit has at least one microcontroller, at least one memory having a plurality of memory cells and at least one debug interface, and the debug interface has a monitoring functionality for observing the memory content, and by means of the debug interface a first point in time of the control unit for writing a first value to a first memory cell is detected, and a triggering point in time for a processing routine by the manipulation unit is obtained as the result based on the information transmitted to the manipulation unit by the debug interface at the first point in time, and at a second point in time, a second value is written to the first memory cell by the manipulation unit by means of the processing routine via the debug interface before the first memory cell is read by the control unit at a third point in time.
