Abstract

A communication control apparatus includes a communicator for communicating with an electronic control unit (ECU), an interface connected to a diagnostic device, and a controller for activating a security diagnostic routing module when the diagnostic device is initially connected to the interface, and for performing routing between the electronic control unit (ECU) and the diagnostic device using the security diagnostic routing module.

Claims

1. A vehicle comprising:

a monitoring unit for periodically monitoring a vehicle state;

a plurality of electronic control units (ECUs); and

a communication control device configured to activate the security diagnostic routing module when the monitored vehicle state information satisfies a setup condition of a security diagnostic routing module, and to control routing of at least one ECU from among the plurality of ECUs using the security diagnostic routing module,

wherein the monitored vehicle state information does not satisfy the setup condition of the security diagnostic routing module, the communication control device controls general diagnostic routing between the diagnostic device and the at least one ECU using a general diagnostic routing module; and

when the security diagnostic routing module is activated, deactivates the diagnostic routing module,

wherein the monitoring unit monitors a vehicle speed and the number of opening/closing times of doors provided in the vehicle; and

the communication control device obtains a mileage of the vehicle on the basis of the monitored vehicle speed, determines that the setup condition is satisfied when the obtained mileage is equal to or longer than a reference distance, and determines that the setup condition is satisfied when the number of door opening/closing times is equal to or higher than a reference number of door opening/closing times.

2. The vehicle according to claim 1, wherein the communication control device includes a communicator for communicating with the plurality of ECUs;

an interface connected to the diagnostic device; and

a controller for authenticating the diagnostic device when the diagnostic device is connected to the interface, and for performing routing between the diagnostic device and the at least one ECU using the security diagnostic routing module when the diagnostic device is successfully authenticated.

3. The vehicle according to claim 1, wherein

the communication control device confirms time points obtained when the monitored vehicle speed is equal to or higher than a reference speed, calculates the sum of confirmed time points, and determines that the setup condition is satisfied when the sum of the time points is equal to or longer than a reference time.

4. The vehicle according to claim 1, wherein the monitoring unit monitors the number of ignition on/off operations;

and

the communication control device determines that the setup condition is satisfied when the number of ignition on/off operations is equal to or higher than a reference number of ignition on/off operations.

5. The vehicle according to claim 1, wherein the monitoring unit monitors the number of position change times of a gearshift;

and

the communication control device determines that the setup condition is satisfied when the number of position change times of the gearshift is equal to or higher than a reference number of position change times of the gearshift.

6. The vehicle according to claim 1, wherein the monitoring unit monitors the number of manipulation times of a wiper control lever;

and

the communication control device determines that the setup condition is satisfied when the number of manipulation times of the wiper control lever is equal to or higher than a reference number of manipulation times of the wiper control lever.

7. The vehicle according to claim 1, wherein the monitoring unit monitors the number of ON operations of a turn indicator lamp;

and

the communication control device determines that the setup condition is satisfied when the number of ON operations of the turn indicator lamp is equal to or higher than a reference number of ON operations of the turn indicator.

8. A method for controlling a vehicle including a communication control device and a plurality of electronic control units (ECUs), the method comprising:

monitoring a state of the vehicle;

determining whether a setup condition of a security diagnostic routing module is satisfied on the basis of the monitored vehicle state;

if the monitored vehicle state satisfies the setup condition of a security diagnostic routing module, activating the security diagnostic routing module; and

if a diagnostic device is connected to an interface of the communication control device, controlling security diagnostic routing between the diagnostic device and at least one ECU of the plurality of ECUs using the security diagnostic routing module,

if the monitored vehicle state does not satisfy the setup condition of the security diagnostic routing module, controlling general diagnostic routing between the diagnostic device and the at least one ECU using a general diagnostic routing module; and

if the security diagnostic routing module is activated;

deactivating the general diagnostic routing module,

wherein the monitoring of the vehicle state includes;

monitoring a mileage of the vehicle and the number of opening/closing times of doors provided in the vehicle;

wherein the determining of whether the setup condition of the security diagnostic routing module is satisfied on the basis of the monitored vehicle state includes;

determining that the setup condition is satisfied when the mileage is equal to or longer than a reference distance; and

determining that the setup condition is satisfied when the number of door opening/closing times is equal to or higher than a reference number of door opening/closing times.

9. The method according to claim 8, further comprising if the diagnostic device is connected to the interface of the communication control device, authenticating the diagnostic device;

and

if the diagnostic device is successfully authenticated, controlling security diagnostic routing between the at least one ECU and the diagnostic device through the communication control device; and

if authentication of the diagnostic device fails, denying the security diagnostic routing between the at least one ECU and the diagnostic device through the communication control device.

10. The method according to claim 8, wherein the step of monitoring the vehicle state further includes monitoring at least one of a speed of the vehicle, the number of ignition ON/OFF operations, the number of position change times of a gearshift, the number of manipulation times of a wiper control lever, and the number of ON operations of a turn indicator lamp.

11. The method according to claim 8, further comprising if the diagnostic device is initially connected to the interface of the communication control device, activating the security diagnostic routing module.
