COMMUNICATION DEVICE, COMMUNICATION SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/125215
Kind Code:
A1
Abstract:
The disclosed communication device is provided with: an oscillating circuit (602) that generates a signal containing a signal potential having a baseline potential as a baseline; a first terminal (TS1) for communicating with a vehicle (10); and a first resistance circuit (RB) that is connected between the output of the oscillating circuit (602) and the first terminal (TS1), and of which the resistance value changes in accordance with a first input signal (SB). Preferably, the vehicle (10) contains: a second terminal (TS2) that is connected to the first terminal (TS1); and a second resistance circuit (RA) that is connected between the second terminal (TS2) and a ground node (512) to which the baseline potential is applied. In the vehicle (10), a first signal retrieval node (N1) is provided on a pathway linking the second terminal (TS2) and the second resistance circuit (RA).
