Description

System for examinating the vehicle at remote place}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle inspection system, and more particularly, to a vehicle remote inspection system for receiving various information about a driving vehicle wirelessly so as to inspect the vehicle remotely.

BACKGROUND ART Currently spreading vehicles, especially passenger vehicles, are equipped with an electronic control device including various sensing means. In the past, a speedometer, pressure gauge, flow meter, oil level meter, and the like were used to electrically convert the measured values and display them on the front panel. I use it. The most basic and important thing is the injector which is attached to the intake manifold side instead of the vaporizer.

In addition, many devices required for driving a vehicle have been electronicized and can be controlled automatically, but in the event of a failure, most of them cannot be identified visually. There are frequent situations that cannot be done.

On the other hand, the vehicle must periodically check or maintain its condition for safe driving. However, it is not easy to visit the workshop for such work in busy daily life, so the inspection and maintenance are being replaced by periodic inspections (once or twice a year) prescribed by law.

Periodic inspection or maintenance of the vehicle extends the life of the vehicle and prevents accidents and breakdowns during driving.

SUMMARY OF THE INVENTION An object of the present invention to the above is to provide a vehicle remote inspection system that can facilitate vehicle inspection. That is, a more specific purpose is to provide a vehicle remote inspection system that can facilitate the inspection or maintenance of the vehicle at the time of failure of the vehicle or at the time required by the driver.

To this end, the present invention provides a system for applying an existing data communication system between a vehicle and a service center (or A / S center). Various information on driving conditions generated in a vehicle is obtained from an electrical control unit (ECU), which is required in a vehicle having an electronic control device, and as a communication means, existing communication such as a wireless telephone terminal rl. Use or utilize the means.

The above object includes: an electrical control unit (ECU) for receiving various physical data related to the vehicle state from various sensing means for use in electronic control of the vehicle; Service system having an input unit for receiving data input to the electronic control unit, a check program for determining the state of the vehicle based on the data, and a communication unit for notifying the driver or maintenance company of the result of the determination. and; And a data transmission means for transferring the data between the electronic control unit and the service system.

According to a feature of the present invention, the service system may be operated by an Internet service company or a mobile communication provider, and informs the maintenance shop (or A / S center) and / or the driver of the determination result of the vehicle's abnormality. Provide services that connect the operator with the repair shop.

Here, the wireless telephone terminal owned by the driver may be used for data transmission. In addition, the Internet service company may provide a periodic and systematic vehicle management service for the vehicle owned by the driver as a member.

Specific embodiments according to the basic system as described above will be described with reference to the accompanying drawings.

1 is a configuration diagram of a system installed in a vehicle in a vehicle remote inspection system. The electronic control unit 2 (ECU) of the vehicle according to the present invention is connected to the control unit 4 by a connector. The control unit 4 stores various physical data of the vehicle input into the electronic control unit in the data storage unit 6.

Data input to the electronic control unit 2 is input from many sensing means 8 installed in the vehicle. The sensing means measures the speed of the vehicle, RPM, the angle of rotation of the crankshaft, the position intake of the accelerator pedal, the displacement, the hydraulic pressure, the temperature of the coolant, and the like.

The electronic control unit 2 controls the mixing ratio, ignition timing, injection amount and injection timing of the air-fuel based on the above information. That is, a large amount of driving state related information is input to the electronic control unit.

The controller 4 backs up the information to the data storage unit according to an external signal. The controller may receive the data for a predetermined time unit (for example, one minute) and perform calculation according to a pre-stored program. The calculation result will be the basic data for determining the abnormality of the vehicle. According to the embodiment, the controller itself may determine whether there is a basic abnormality of the vehicle, such as lack of oil and relaxation of the timing belt.

According to the present invention, the data about the vehicle stored in the data storage unit may be transmitted to the outside by the radiotelephone terminal 10 carried by the driver. To this end, the radiotelephone terminal 10 and the control unit 4 are connected by a data bus.

FIG. 2 is a schematic diagram illustrating an entire system of the present invention including the system of FIG. 1. 3 is a block diagram showing the configuration and operation of a service system.

The vehicle remote inspection system according to the present invention is provided with a service system 12 that receives information related to a vehicle wirelessly and analyzes it to determine whether there is an abnormality of the vehicle. When it is determined that there is a problem with the vehicle, the service system 12 notifies the repair shop side 14 (or the after-sale center side) and the driver of the detailed information about it. To this end, the service system has the technology to determine the communication equipment and vehicle status. According to this embodiment, the service system provides a service which periodically and systematically checks a vehicle of a registered member by operating a membership system.

The service system 12 builds an overall database of vehicles such as age, failure and accident history. Such information can be usefully used in the trade of used vehicles, so that the user can sell the vehicle with a fair evaluation. This may be useful information for the buyer who wants to purchase a specific vehicle.

If the service system needs to be replaced due to an abnormality in the checked vehicle, the service system may transmit a service such as a purchase and replacement instruction of the corresponding part to the driver's radiotelephone 10 or the PC 16 held by the driver. There will be.

When a failure occurs during operation, the service system may provide a service that determines the cause of the failure and connects the driver with the nearest maintenance shop.

As described above, the service system 12 may be a system operated by an Internet service provider or a mobile communication provider. That is, the driver accesses the service company's Internet site, enters an ID and password, and transmits objective data related to the vehicle status through a wireless telephone to carry and check whether there is a failure.

The service system 12 has a check program for determining a vehicle state based on data input to the ECU. The program can also be used as an aid to determine information such as problems that occur frequently for each type of vehicle and the failure history of the vehicle.

According to the above system, the vehicle driver can be inspected at the time of failure or regularly. Since this is done through wireless communication and the Internet network, it is beneficial to receive the service as described above regardless of time and place.

In addition, since it is determined based on the objective and substantial data related to the vehicle provided from the electronic control unit, it is possible to more accurately, faster and convenient vehicle inspection. In addition, since the system according to the present invention can provide accurate information related to a specific vehicle, it can be extremely useful in the used sale market.
