Abstract
Particularly in conjunction with prototype testing of new control units, in addition to the current control unit according to an earlier variant, the control unit according to a newer control unit variant is also present in a motor vehicle (preferably motor vehicle prototypes), wherein a device decides whether the control commands from the first control unit or from the second control unit are forwarded during operation to the devices (actuators) of the motor vehicle to be controlled.
Claims19
A device providing control commands for at least one device to be controlled in a motor vehicle, comprising:
- a first data input for first control commands of a predetermined type from a first control device according to an earlier control device variant;
- a second data input for second control commands of the predetermined type from a second control device according to a newer control unit variant;
- a data output to output respective control commands for the at least one device to be controlled;
- and
- a data processing device which is designed to determine, based on an analysis of at least the second control commands, whether the first control commands or the second control commands are the respective control commands forwarded to the at least one device to be controlled, and to effect a corresponding output via the data output.
A motor vehicle with a device providing control commands for at least one device to be controlled, an input of which is coupled to a data output of the device, and
- a first control device according to an earlier control unit variant, an output of which is coupled to a first data input of the device, and a second control device according to a more recent control unit variant, the output of which is coupled to a second data input of the device.
A method for controlling at least one device of a motor vehicle, in particular an actuator of the motor vehicle, comprising:
- supplying input data to a first control device according to an earlier control unit variant, which issues first control commands, and to a second control device according to a newer control unit variant, which issues second control commands;
- receiving at least the second control commands and, using the second control commands, determining whether the first control commands and the second control commands are transmitted to the at least one device, and outputting respective control commands to the at least one device accordingly, based on the determining.
