Device and method of controlling a drive unit
First Claim
1. A device for controlling a drive unit, the drive unit being of an internal combustion engine in a vehicle, the device comprising:
- at least one sensor;
at least one actuator;
a controller; and
at least two processors that exchange information between each other in a non-hierarchical manner;
wherein at least one program memory contains program code and is assigned to each of the at least two processors, and the program code in the at least two program memories is identical.

Abstract
A method and a device for controlling a drive unit, in particular, of an internal combustion engine in a vehicle, in which at least one performance quantity of the drive unit is detected and at least one actuator of the drive unit is controlled with controlled variables, depending on this performance quantity, according to predefinable or preselectable functionalities. In a controller, at least two processors process the possible functionalities, where these functionalities are defined by program code in at least one assigned program memory per processor. These possible functionalities of the processors, i.e., the program codes in the program memories assigned to the processors are identical.
