④ Incident notification and accident record information

The controller 501 may determine whether an accident has occurred through the acceleration sensor. That is, when the amount of impact obtained by integrating the acceleration value obtained from the acceleration sensor has a value greater than or equal to the threshold value, it is determined as an accident and immediately informs the external information output device 7 of the accident, and the speed of the vehicle before and after the accident recognition time. , Steering angle, impact amount, etc. can be recorded in the storage unit 507 as accident record information and later transmitted to the external information output device 7 according to a user's request.

⑤ Driving Propensity Analysis Information

The controller 501 may analyze and store a driver's driving tendency using the acceleration and the value input from the gyro sensor and transmit the same to the external information output device 7 when the user requests it. have. The driving tendency analysis information includes information such as rapid acceleration, sudden braking, sudden steering, and overspeed.

⑥ Update software of in-vehicle electronic controls

The controller 501 receives the software of the in-vehicle electronic control devices 5 via wire / wireless and transmits it to the in-vehicle electronic control device 5 when a user request is made through the external information output device 7. By doing so, the electronic control devices 5 can be supported to update their own software.

In addition, the control unit 501 can support a car unit function outputting the vehicle consumable replacement time according to the vehicle travel distance through the voice output unit 511, a long time driving warning, a long time sleep warning in a car starting state, and the like. Do.

As described above, the present invention can provide convenience to a vehicle operator by providing vehicle information, driving record information, accident notification and accident record notification, and driving tendency analysis information as vehicle driving information in addition to providing self-diagnosis information.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is determined by the appended claims and is not limited to the above-described embodiments. And improvements, changes or modifications apparent to those skilled in the art for the invention described in the claims are included in the scope of the present invention.

As described above, the present invention provides a vehicle information processing apparatus in which a connector connected corresponding to a vehicle-side self-diagnosis connector is integrated, whereby the vehicle self-diagnosis result obtained from an in-vehicle electronic control apparatus or the like is transmitted to the external information output device. As a result, it is possible to receive and process the self-diagnosis result even if an expensive device such as a telematics terminal does not include or support an interface unit such as a self-diagnosis connector or a cable connection connector.

In addition, since the telematics terminal can be used regardless of the type of communication protocol with the vehicle-side electronic control apparatus, the telematics terminal manufacturing cost can be reduced by eliminating the need to develop a telematics terminal according to the communication protocol.

In addition, the vehicle driver has an advantage of receiving various information such as vehicle information, driving record information, failure occurrence, accident notification and accident record information, driving tendency analysis information, and the like in addition to the self-diagnosis information through the device of the present invention.
