System for transmitting signals in a motor vehicle
First Claim
1. A system for transmitting sensor signals from a detection device to a receiver in a motor vehicle comprising:
- a sensor carried by said motor vehicle for sensing information regarding said motor vehicle and generating said sensor signals representing said information;
an information display device located in a driver cabin of said motor vehicle for receiving said sensor signals and outputting said information represented by said sensor signals; and
a transmission conduit for transmitting said sensor signals from said sensor to said information display device, said transmission conduit including an existing vehicle transmission line designated for purposes other than transmitting said sensor signals;
whereby said transmission conduit allows the transmission of said sensor signals through a pre-existing transmission line in said motor vehicle.

Abstract
The invention is a system for transmitting signals in a vehicle, comprising a sensor that generates sensor signals, an information display device that receives the sensor signals and a transmission conduit through which the sensor signals are transmitted. The transmission conduit comprises transmission line that may be dedicated for purposes other than transmitting the sensor signals, modulator, demodulator and control device. When the sensor is actuated, the control device acts to detect the presence of current in the transmission line and if present, actuates the modulator thus, modulating the sensor signals prior to their transmission via the transmission line. Simultaneously, the control device actuates the demodulator for demodulating the modulated sensor signals prior to their transmission to the information display device. If, however, current is not detected in the transmission line when the sensor is actuated, the sensor signals are transmitted via the transmission line without being modulated or demodulated.

15. A transmission conduit for transmitting sensor signals in a motor vehicle comprising:
-
a sensor for sensing information regarding said motor vehicle and generating sensor signals representing said information;
a signal modulator for creating modulated sensor signals by modulating said sensor signals for transmission over said transmission line;
a signal demodulator for demodulating said modulated sensor signals for display on said display device;
a plurality of transmission lines interconnecting said signal modulator and said signal demodulator;
an information display device connected to said signal demodulator for receiving and outputting said information represented by said sensor signals;
a control device disposed between said signal modulator and said signal demodulator and connected to each of said plurality of transmission lines;
wherebysaid control device detects current in said plurality of transmission lines and upon detecting said current, said control device actuates said signal modulator to modulate said sensor signals prior to being transmitted through said plurality of transmission lines and to actuate said signal demodulator to demodulate said modulated sensor signals prior to being transmitted from said plurality of transmission lines to said information display device, allowing said signals to be transmitted through said plurality of lines simultaneously with said current. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
