Abstract

A wireless diagnostic module includes a connection port connected to a connector provided in a first appliance; a first signal transceiving unit to transceive a signal corresponding to a first communication protocol by making communication with the first appliance connected through the connection port; a signal converting unit to convert the signal corresponding to the first communication protocol transmitted through the first signal transceiving unit into a signal corresponding to a second communication protocol; and a second signal transceiving unit to transmit the signal corresponding to the second communication protocol, which is converted through the signal converting unit, to a second appliance, wherein the first communication protocol comprises at least one of ISO, KWP, PWM, CAN and VWP supported by the connector provided in the first appliance, and the second communication protocol comprises a wireless communication protocol for wireless communication between the first and second appliances.

Claims

1. A wireless diagnostic module comprising:

a connection port connected to a connector provided in a first appliance;

a first signal transceiving unit to transceive a signal corresponding to a first communication protocol by making communication with the first appliance connected through the connection port;

a signal converting unit to convert the signal corresponding to the first communication protocol transmitted through the first signal transceiving unit into a signal corresponding to a second communication protocol; and

a second signal transceiving unit to transmit the signal corresponding to the second communication protocol, which is converted through the signal converting unit, to a second appliance,

wherein the first communication protocol comprises at least one of ISO, KWP, PWM, CAN and VWP supported by the connector provided in the first appliance, and the second communication protocol comprises a wireless communication protocol for wireless communication between the first and second appliances.

2. The wireless diagnostic module of claim 1, wherein the second signal transceiving unit receives a signal corresponding to the second communication protocol from the second appliance and outputs the signal corresponding to the second communication protocol to the signal converting unit, and

the signal converting unit converts the signal corresponding to the second communication protocol, which is output through the second signal transceiving unit, into a signal corresponding to the first communication protocol, and outputs the signal corresponding to the first communication protocol to the first signal transceiving unit.

3. The wireless diagnostic module of claim 2, wherein the first appliance is a vehicle, the second appliance is a diagnostic equipment for diagnosis of the vehicle, and the connector comprises an on board diagnostics (OBD) connector provided in the vehicle.

4. The wireless diagnostic module of claim 2, wherein the first appliance is a diagnostic equipment for diagnosis of a vehicle, the second appliance is the vehicle, and the connector is provided in the diagnostic equipment.

5. The wireless diagnostic module of one of claim 3, wherein the connection port is inserted into the connector as the connection port has a shape corresponding to a shape of the connector provided in the first appliance.

6. The wireless diagnostic module of one of claim 4, wherein the connection port is inserted into the connector as the connection port has a shape corresponding to a shape of the connector provided in the first appliance.

7. The wireless diagnostic module of claim 3, wherein a signal received from the second appliance and transmitted to the first appliance is a diagnosis message for internal diagnosis of the vehicle, and a signal received from the first appliance and transmitted to the second appliance comprises a self-diagnosis information generated in response to the diagnosis message.

8. The wireless diagnostic module of claim 4, wherein a signal received from the first appliance and transmitted to the second appliance is a diagnosis message for diagnosis of the second appliance, and a signal received from the second appliance and transmitted to the first appliance comprises a self-diagnosis information of the second appliance generated in response to the diagnosis message.

9. A wireless diagnostic system comprising:

a vehicle comprising a first connector;

a diagnostic equipment comprising a second connector;

a first wireless diagnostic module connected to the first connector of the vehicle; and

a second wireless diagnostic module connected to the second connector of the diagnostic equipment,

wherein the first wireless diagnostic module converts a signal corresponding to a first communication protocol, which is transmitted through the first connector, into a signal corresponding to a second communication protocol to be transmitted to the second wireless diagnostic module, or converts a signal corresponding to the second communication protocol, which is transmitted from the second wireless diagnostic module, into a signal corresponding to the first communication protocol to be output to the first connector, and

the second wireless diagnostic module converts a signal corresponding to the first communication protocol, which is transmitted through the second connector, into a signal corresponding to the second communication protocol to be transmitted to the first wireless diagnostic module, or converts a signal corresponding to the second communication protocol, which is transmitted from the first wireless diagnostic module, into a signal corresponding to the first communication protocol to be output to the second connector.

10. The wireless diagnostic system of claim 9, wherein the first connector is an on board diagnostics (OBD) connector provided in the vehicle.

11. The wireless diagnostic system of claim 9, wherein the first communication protocol comprises at least one of ISO, KWP, PWM, CAN, and VWP supported by the first and second connectors, and
