Description

Safety management apparatus for vehicles using an audio / video interface function}

The present invention relates to a vehicle safety management device using an audio / video interface function.

In general, a vehicle camera includes a rear camera for parking convenience, an image black box for preventing accidents, and lane departure prevention. In the case of a vehicle parking rear camera module, various types of products, such as analog module type (for example, composite) to digital module type (for example, USB), have been introduced and the market is expanding. However, due to the limitation of the interface with the main terminal, such as a navigation terminal, a car DVD player, such as a display device, it is difficult to attach additional devices with various functions. Accordingly, it is urgent to develop an integrated terminal for interfacing various types of additional devices.

In addition, in the case of vehicle video black box and lane departure prevention camera products, speed data plays an important judgment factor, but currently it does not function in the underground parking lot, tunnel area, etc. There is. Therefore, it is necessary to expand data accuracy and marketability by correcting with accurate vehicle speed data through ECU and sharing and sharing ECU information.

In addition, the vehicle has a connector (OBD) for acquiring vehicle information, through which the control state of the ECU, engine sensor information, etc. can be acquired in real time, so that the actual driving data of the vehicle can be confirmed. The vehicle connector can receive the battery power directly without going through the cigar jack, thereby solving the power part of the additional function devices for the vehicle, and real-time monitoring of the running speed of the vehicle through the connector enables various information services using the same. The interface of the additional equipment for vehicles is released in various ways such as RS232, USB, A / V, but in the case of RS232, USB, it is difficult to apply jointly in the main terminal, and it is virtually inapplicable to existing products. There is a limit to marketing, but the A / V type interface does not require the development of the display main terminal, and all services are possible by simply connecting the connector. Therefore, it is possible to enter the new market as well as the existing market. Therefore, it is necessary to implement low cost integrated function service by developing A / V type integrated terminal by integrating vehicle information with ECU information in various types of additional function terminals for vehicles.

In addition, in the case of AM (aftermarket), a TPMS air pressure measuring instrument has been widely distributed in the form of a receiver attached to a measuring sensor and a separate display, but it is difficult to enter the market due to the high price. Therefore, if the received data is communicated with the integrated terminal and displayed on the navigation or other vehicle display terminals, the market will be expanded by inducing the commercialization of a simple receiving module except for the high part of the cost, such as the receiver or display, which is a product of the TPMS function. Could be.

In addition, the current vehicle diagnostic technology is an exclusive property of a car manufacturer, manufactured by a related company in the form of a diagnostic scanner, which is dedicated to a vehicle maintenance office, and is being sold for maintenance offices and small-scale maintenance services.

In addition, for the purpose of personalization of vehicle diagnostic technology and the generalization of information, personal diagnostic devices using dedicated display devices are being distributed and distributed to vehicle diagnostic devices, but this also rides on the existing vehicle-related terminal market rather than creating a vehicle diagnostic and information service market. In one form, the market was limited and it was difficult to create a new market that would expand into the vehicle information service market.

In addition, in the past, a diagnostic-only module for navigation has been released. However, in order to implement a diagnostic function, a service that can be serviced only for the development of a new product has to be developed due to the co-development with a navigation manufacturer and a hardware interface, OS, and APP program. there was.

It is an object of the present invention to solve the above problems, the audio / video interface function that can be used directly connected to the navigation terminal, car TV, etc. previously sold using the A / V interface equipment without additional development of the vehicle main display terminal It is to provide a vehicle safety management device using.

Another object of the present invention, using the audio / video interface function to easily check the image information of the vehicle, vehicle operation information through the ECU, vehicle diagnostic information, etc. through the navigation terminal, vehicle TV, etc. connected to the A / V interface equipment To provide a vehicle safety management device.

The vehicle safety management apparatus using the audio / video interface function according to an embodiment of the present invention for achieving the above object, as a device of the navigation terminal, a vehicle TV provided in the vehicle, the data transmitted from the A / V interface device It is connected to a vehicle display terminal that displays vehicle image information, vehicle operation information and vehicle diagnostic information on the screen, a camera provided in the vehicle, and an ECU board based on the vehicle image information and vehicle operation through the ECU. An A / V interface device that provides information and vehicle diagnostic information to a vehicle display terminal, and an ECU board that is connected to the A / V interface device by a connector and provides vehicle driving information of a running vehicle as an A / V interface device. It may include.

In addition, the vehicle safety management apparatus using the audio / video interface function according to an embodiment of the present invention, is provided inside the vehicle is connected to the A / V interface device and the connector, the image information of the vehicle A / V interface device It may further include a camera to provide.

The A / V interface device may analyze the parts consumption cycle and driving tendency of the vehicle based on the diagnostic information of the vehicle, and display the result on the vehicle display terminal to provide the driver.

As described above, according to the vehicle safety management apparatus using the audio / video interface function of the present invention, attempts to integrate various additional function devices of the navigation terminal and the vehicle DVD market, and the technical problem of the mounting and increase the installation cost, which is a problem of the vehicle device In this way, it is possible to lead the expansion of the navigation application vehicle information terminal market other than the navigation market.

In addition, when the A / V interface device is connected to the existing navigation terminal and the vehicle TV, it is expected that a new maintenance culture will be formed to start and check the normal state of the vehicle and start driving. The driving record is stored in real time to maintain the vehicle. By informing the replacement cycle of consumables (engine oil, timing belt, etc.), professional service is possible in vehicle management.

In addition, it informs the driver of driving habits (start-up, sudden braking, rapid turn, etc.) data in real time to correct wrong driving habits such as violent driving, and prevents accidents by analyzing the driving tendency along with the driving record of the driver during the next driving. Induce driving.

In addition, by analyzing the driving tendency together with the self-diagnosis maintenance result that is automatically detected when driving a vehicle, it is possible to prevent failure transition, fuel efficiency, and power degradation due to delay in maintenance.

In addition, by monitoring the sensor state for engine control in real time, the driver can immediately notify the driver of any serious abnormalities that may occur during driving, such as engine oil temperature, so that the driver can perform a quick response even when an abnormality occurs.

In addition, it can maximize the efficiency of the equipment, such as preliminary inspection, maintenance reservation, maintenance progress, maintenance results, excessive maintenance and preventive maintenance, as well as reduce costs.
