Abstract
A wire based control system for controlling a motor vehicle has an input having a transmitting unit for emitting signals for executing input commands, a first transmission channel for transmitting a first signal, a second transmission channel for transmitting a second signal, a receiving unit for receiving the signals, and an execution for executing the input commands.
Claims20
A wire based control system for controlling a motor vehicle, said wire based control system comprising:
- an input means having a transmitting unit for emitting signals for executing input commands,
- a first transmission channel connected to the transmitting unit of the input means, the first transmission channel comprising a plurality of discrete bidirectional electrical cables for transmitting a first signal of said signals,
- a second transmission channel connected to the transmitting unit of the input means, the second transmission channel comprising a plurality of discrete unidirectional optical cables for transmitting a second signal of said signals,
- a plurality of execution means for executing the input commands, wherein each execution means is coupled to a respective electrical cable of the first transmission channel and a respective optical cable of the second transmission channel,
- wherein each execution means includes a receiving unit for receiving said first signal and said second signal of said signals from said first and second transmission channels,
- wherein said first transmission channel carries the first signal of said signals from the transmitting unit to the receiving units by way of a central control unit,
- wherein said second transmission channel carries the second signal of said signals from the transmitting unit directly to the receiving units without the aid of a control unit disposed between the transmitting unit and the receiving units, and
- wherein the first and second transmission channels are isolated from each other for redundancy purposes.

A wire based control method for controlling a motor vehicle, said method comprising:
- emitting signals for executing an input command using a transmitting unit of an input means of the motor vehicle,
- transmitting a first signal of said signals via a first transmission channel of the motor vehicle that is connected to the transmitting unit of the input means, the first transmission channel comprising a plurality of discrete bidirectional electrical cables,
- transmitting a second signal of said signals via a second transmission channel of the motor vehicle that is connected to the transmitting unit of the input means, the second transmission channel comprising a plurality of discrete unidirectional optical cables,
- receiving the first signal and the second signal of said signals at respective receiving units of a plurality of execution means of the motor vehicle for executing the input command, wherein each execution means is coupled to a respective electrical cable of the first transmission channel and a respective optical cable of the second transmission channel, and
- executing the input command using the plurality of execution means,
- wherein said first transmission channel carries the first signal of said signals from the transmitting unit to the receiving units by way of a central control unit,
- wherein said second transmission channel carries the second signal of said signals from the transmitting unit directly to the receiving units without the aid of a control unit disposed between the transmitting unit and the receiving unit, and
- wherein the first and second transmission channels are isolated from each other for redundancy purposes.
