VEHICLE, COMMUNICATION SYSTEM, AND COMMUNICATION DEVICE
First Claim
1. A vehicle communicating with a communication device, the communication device including:
- a signal generating unit for generating a signal including a signal potential that is based on a reference potential;
a first terminal for communicating with the vehicle; and
a first resistance circuit connected between an output of said signal generating unit and said first terminal and having a resistance value corresponding to a requested operation mode requested to the vehicle,the vehicle comprising;
a second terminal connected to said first terminal;
a second resistance circuit connected between a node fed with said reference potential and said second terminal; and
a vehicle control unit for setting an operation mode of the vehicle,said vehicle control unit detecting the signal potential of said signal via a first signal extraction node provided on a path connecting said second terminal and said second resistance circuit to each other, so as to set the operation mode of the vehicle at said requested operation mode corresponding to the resistance value of said first resistance circuit.

Abstract
A communication device includes a first resistance circuit connected between an output of a signal generating unit and a first terminal and having a resistance value corresponding to a requested operation mode requested to a vehicle. The vehicle includes: a second resistance circuit connected between a ground node fed with a reference potential and a second terminal; and a vehicle control unit for setting an operation mode of the vehicle. The vehicle control unit detects a signal potential of a signal via a first signal extraction node provided on a path connecting the second terminal and a second resistance circuit to each other, and sets the operation mode of the vehicle at the requested operation mode corresponding to the resistance value of the first resistance circuit.
