Abstract
A device for controlling an engine includes: a first control circuit having a first controller, and a second control circuit having a second controller, the controllers being designed to control a state variable of the engine in each case. The second controller is disposed in such a way that it lies closer to the engine than the second controller in terms of signal technology.
Claims18
A system for controlling an electric motor of a vehicle, the system comprising:
- a first control device which includes a first controller to control a torque of the electric motor, the first controller outputting a first signal variable to a data bus as a function of an actual torque of the electric motor and a setpoint torque;
- and
- a second control device connected downstream from the first control device via the data bus, the second control device receiving the first signal variable over the data bus and including:
- a second controller to control a speed of the electric motor, the second controller generating a second signal variable as a function of an actual speed of the electric motor and a setpoint speed;
- and
- a unit which forms a resulting signal variable as a function of the first and second signal variables;
- wherein the second controller is situated closer to the electric motor than the first controller in terms of signal technology.

A method for controlling an electric motor of a vehicle, the method comprising:
- generating a first signal for use in controlling a torque of the electric motor using a first controller of a first control device, the first signal variable being a function of an actual torque of the electric motor and a setpoint torque, and outputting the first signal variable to a data bus;
- generating a second signal for use in controlling a speed of the electric motor using a second controller of a second control device connected downstream from the first control device via the data bus, the second signal variable being a function of an actual speed of the electric motor and a setpoint speed, the second control device receiving the first signal variable over the data bus;
- and
- forming a resulting signal variable as a function of the first and second signal variables using a unit of the second control device,
- wherein the second controller is situated closer to the electric motor than the first controller in terms of signal technology.

A device for controlling an electric motor of a vehicle, the device comprising:
- a controller to control a speed of the electric motor, the controller generating a signal variable as a function of an actual speed of the electric motor and a setpoint speed;
- and
- a unit which forms a resulting signal variable as a function of the signal variable and an additional signal variable that the device receives over a data bus from an additional device, connected upstream from the device via the data bus, having an additional controller to control a torque of the electric motor, the additional signal variable being a function of an actual torque of the electric motor and a setpoint torque,
- wherein the controller is configured to be situated closer to the electric motor than the additional controller in terms of signal technology.
