  • Method and arrangement for controlling an internal combustion engine, comprising at least two control units
    Patent number: 9719452
    Abstract: A method for controlling an internal combustion engine, wherein a first engine control device generates a control signal to actuate a function of the engine. A switchover device transmits the control signal of the first control device to the engine to actuate the function of the engine. The first control device transmits a sign-of-life signal which indicates functionality of the control device to the switchover device. The first engine control device does not transmit the sign-of-life signal or transmits the signal incorrectly if a fault occurs which endangers proper actuation of the function of the engine by the first engine control device. If the sign-of-life signal of the first engine control device is not or is incorrectly received by the switchover device, the switchover device stops transmitting the control signals of the first engine control device and starts transmitting a control signal generated by a second engine control device to the engine to actuate the function of the engine.
