Abstract
Disclosed herein are a connection cable, an antenna connection diagnosis device, a vehicle including the same, and an antenna connection diagnosis method. The antenna connection diagnosis device includes a first cable having a first connector installed at one end thereof and a first connection diagnosis connector installed at the other end. A second cable has a second connector, which is capable of being coupled to the first connection diagnosis connector, formed at one end thereof. A diagnoser is configured to diagnose whether the first cable and the second cable are connected using the first connection diagnosis connector.
Claims20
A device comprising:
- a first cable having a first connector installed at one end thereof and a first connection diagnosis connector installed at an opposite end;
- a second cable having a second connector formed at one end thereof, the second connector being capable of being coupled to the first connection diagnosis connector;
- and
- a diagnoser configured to use the first connection diagnosis connector to diagnose whether the first cable and the second cable are connected;
- wherein the first connection diagnosis connector comprises:
- a first signal line to which an electrical signal is to be transmitted;
- a first ground spaced apart from the first signal line;
- and
- a first resistor formed between the first signal line and the first ground.
An antenna connection diagnosis method comprising:
- applying a control voltage to a second diagnoser signal line branched from a first diagnoser signal line, wherein the first diagnoser signal line is electrically connected to a first cable having a first connector installed at one end thereof and a first connection diagnosis connector installed at opposite end and a second cable having a second connector, which is coupled to the first connection diagnosis connector;
- measuring a voltage of a third diagnoser signal line branched from the second diagnoser signal line in response to the application of the control voltage;
- and
- determining whether the first cable and the second cable are not connected based on the measured voltage.
An antenna connection cable comprising:
- a first cable having a first connection diagnosis connector installed at one end thereof;
- and
- a second cable having a first connector formed at one end thereof and a second connection diagnosis connector installed at the other end, the first connector coupled to the first connection diagnosis connector;
- wherein the first connection diagnosis connector comprises:
- a first signal line to which an electrical signal is to be transmitted;
- a first ground spaced apart from the first signal line;
- and
- a first resistor formed between the first signal line and the first ground;
- and
- wherein the second connection diagnosis connector comprises:
- a second signal line to which the electrical signal is to be transmitted;
- a second ground spaced apart from the second signal line;
- and
- a second resistor, which is different from the first resistor, formed between the second signal line and the second ground.
