Abstract

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.

Claims

1. A method for processing data, the method comprising:

providing a vehicle control unit, an influencing device connectable to the vehicle control unit, and a data processing unit connectable to the influencing device, the influencing device having a first execution unit, the vehicle control unit and the influencing device being arranged in a motor vehicle or the vehicle control unit and the influencing device being arranged on a test bench or laboratory bench;

running a first program in the vehicle control unit;

exchanging data according to an XCP protocol and/or a CCP protocol between the data processing unit and the influencing device;

providing a second execution unit in the influencing device;

executing, via the second execution unit, predetermined data processing steps more rapidly than the first execution unit;

checking the data exchanged via the XCP protocol or the CCP protocol for a predetermined criterion; and

processing the data, based on a result of the check, either in the first execution unit or in the second execution unit.

2. The method according to claim 1, wherein the data have a first priority or a second priority, wherein the priority of the data is checked as a criterion, and wherein the data with a first priority are processed in the second execution unit and the data with a second priority are processed in the first execution unit.

3. The method according to claim 1, wherein the data sent from the vehicle control unit to the influencing device are checked for the predetermined criterion, and wherein, based on the result of the check, the data are processed either in the first execution unit or in the second execution unit.

4. The method according to claim 1, wherein the influencing device has a component upstream of the first execution unit and the second execution unit, and wherein, via the upstream component, an apportioning of the data to the first execution unit and to the second execution unit is carried out.

5. The method according to claim 1, wherein an apportioning of the data to the first execution unit and to the second execution unit is carried out via the first execution unit or the second execution unit or the data processing unit interface or the motor vehicle control unit interface.

6. The method according to claim 1, wherein the data processing is carried out in the second execution unit by an FPGA (field-programmable gate array) unit.

7. The method according to claim 1, wherein the first execution unit is a processor unit that carries out a sequential program.

8. The method according to claim 1, wherein the influencing device comprises a third execution unit, wherein at least three types of data are provided, and wherein a first type of data is processed in the first execution unit, a second type of data in the second execution unit, and a third type of data in the third execution unit.

9. The method according to claim 1, wherein the second execution unit and/or the third execution unit are reprogrammed or configured via the first execution unit.
