Abstract
The invention relates to a device and a method for reducing the number of analog inputs at a control device (16). It is proposed that at least two physical signals, which are different from each other, are transmitted at an analog input of the control device (16).
Claims15
A method for reducing a number of analog inputs at a control device (16) with a power converter (14) which is configured as an inverter, the method comprising:
- transmitting a first signal via a first analog input of the control device (16) during a starter operation, and
- transmitting a second signal, different from the first signal at the first analog input of the control device (16) during a running period.
A system (10) comprising:
- an internal combustion engine (11),
- an electric machine (12),
- a power converter (14) configured as an inverter, and
- a control device (16) configured as an engine control device and electrically coupled to the power converter (14),
- a first analog input located at the control device (16), wherein
- the power converter (14) transmits at least two physical signals at the first analog input, a first signal transmitted during an activation period and a second signal transmitted during a running period separate from the activation period, wherein the first and second signals are different from one another.
3 more elements
A method for transmitting an analog signal to a control device, the method comprising:
- reducing a number of analog inputs required for signal transmission by transmitting at least one starting signal via an analog input of the control device during an activation period, and transmitting a running signal, different from the at least one starting signal, at the same analog input of the control device during a running period separate from the activation period.
