Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle control device using a portable terminal,

The present invention relates to an apparatus and method for controlling a vehicle using a portable terminal, and more particularly, to a method and apparatus for controlling and managing a vehicle remotely by communicating with a vehicle terminal installed in the vehicle, And more particularly, to a vehicle control apparatus and method using a portable terminal.

In addition to improving the quality of the vehicle itself, vehicle manufacturers have invested heavily in differentiated customer service and after-sales management of their vehicles. In particular, after-sales management of vehicles is a part of the ongoing investment by vehicle manufacturers in conjunction with the increasingly stringent regulation of automobile emissions.

Conventionally, the driver of the vehicle has taken the form of detecting an abnormality of the vehicle through a malfunction indicator lamp (MIL), which is a fault indicator, or repairing the vehicle at a repair shop due to the occurrence of a malfunction of the vehicle. However, the problem with this post-prescription is that most drivers neglect maintenance due to cost and time problems if the vehicle can be operated despite the fact that most drivers can not detect the abnormal condition of the vehicle in a timely manner or warn through MIL. Even when the vehicle is damaged due to an abnormality or malfunction, it is difficult for the driver to accurately indicate the state of the vehicle. Sometimes, the problem may not be reproduced when the vehicle is visited. Also, there is a limitation in that the mechanic can accurately grasp the condition of the vehicle within a short time, and therefore a guess-and-replace type maintenance has been performed. Therefore, the time required for maintenance is excessive due to trial and error, which causes the driver to be dissatisfied. Furthermore, the damage caused by a car accident caused by improper maintenance of the mechanic may occur. To solve these problems, an OBD (On-Board Diagnostics) system has been proposed, which is a system in which a fault diagnosis function is integrated in a vehicle.

This OBD system was first used by GM, an American car maker in the early 1980s, and in 1988 it was named "OBD I" as the California government imposed an OBD system on all car makers. Until then, the OBD system was only enough for the automotive controller to recognize and store defects in the system, helping the mechanics to repair it later.

Since then, US federal law has required all automakers to comply with the new regulation "OBD II", which has been in force since 1996.

The above-mentioned "OBD II" regulation includes a standardization of an automobile part name, a standardization of a defect code number system, and in particular, a system for checking and diagnosing an automobile exhaust gas level, the system comprising a data link connector 16-pin arrangement is standardized), an oxygen sensor, an exhaust gas recirculation valve (EGR valve), an EVAP vent solenoid, an EVAP fuel tank pressure sensor, and a camshaft position sensor. The system determines whether or not the engine is misfired, whether there is abnormality in the catalytic performance, whether the evaporative gas control device is abnormal, whether there is abnormality in the fuel device, whether there is abnormality in the oxygen sensor, and abnormality in the EGR gas control device. For example, when the exhaust gas exceeds 1.5 times the standard value of the exhaust gas specified in the Federal Test Procedure (FTP), the malfunction indicator lamp (MIL) is turned on.

At present, various sensors (for example, a speed sensor, an acceleration sensor, a door open / close sensor, a railroad stop sensor) are added to the OBD II system to provide various driving information (running time, Time and distance, rapid acceleration / rapid braking, etc.). However, it is also a reality that the OBDII scanner can not diagnose the problems during actual driving through the repair shop operation. In order to ensure more accurate after-care, information on actual vehicle driving is stored for a certain period of time, and vehicle diagnosis is more effective.

In order to achieve the above object, a car black box product has recently been released. However, the way of utilizing the stored driving information is not so different from the conventional wired OBDII scanner. The problem of efficient transmission of vehicle diagnostic information is combined with exhaust gas regulation to provide motivation for OBDIII. OBDIII differs from OBDII in that it first communicates abnormality of vehicle related to exhaust gas more effectively to regulatory / regulatory agency related to workshop and environmental pollution. Currently, roadside reader, local station network station network and satellite have been proposed. However, most of the methods proposed in OBD III are expected to take a considerable period of time until the realization, as they constitute a wide social infrastructure linked with the enactment of laws and regulations. The realization of the remote monitoring should meet the conditions such as the abolition of locality by the global standardization, simplification of the device, transmission of regular driving information, compatibility with the existing OBD II system installed in the vehicle, and low cost. Is not provided.

In addition, since the conventional OBD II system does not reflect the recent development of electronic communication technology, the user's convenience is degraded. Moreover, the OBD II system provides the diagnostic information of the vehicle and can be managed or controlled remotely There is a problem that the user's request can not be reflected.

The background art of the present invention is disclosed in Korean Patent Registration No. 10-0512487 (Registered, Method and System for Efficient Management of Vehicle Operation Information by Bluetooth Based Remote Monitoring).

This feature (standby power minimization, discharge prevention, etc.) has a lot of power consumption and provides information about location information, eco-driving and fault diagnosis, and is an advanced feature compared to closed-circuit devices.

For reference, the Bluetooth 4.0 supports very short data packets (at least 8 octets to a maximum of 27 octets) transmitted at a rate of 1 Mbps for data transmission, and all connections are made with an advanced sniff - Use sniff-subrating. In order to minimize the interference with other technologies sharing the frequency band of 2.4 GHz in frequency hopping, the AFH (Adaptive Frequency Hopping) function used in all versions of the Bluetooth technology standard is used.

The vehicle control apparatus 200 according to the present embodiment includes an OBD2 terminal installed in a vehicle and communicates with an external portable terminal 300 via a second short-

For example, the second short-range communication unit 250 may perform near-field communication (NFC) to easily pair the Bluetooth pairing with the mobile terminal 300 using NFC communication.

For example, it inquires Bluetooth information that can be connected through a search, selects a target among Bluetooth information that can be connected, and requests pairing (sharing a password required for connection). If there is no pairing between the two devices, the two devices request pairing approval. Then, when the two devices approve the pairing, they try to connect.
