Description

  The present invention relates to a remote diagnosis apparatus and a remote diagnosis server for a vehicle, and more particularly to a remote diagnosis apparatus that transmits information for diagnosing an abnormality of the host vehicle to the outside and a remote diagnosis server that diagnoses an abnormality of the vehicle.

  Various systems for monitoring or managing a vehicle based on information transmitted from the vehicle side have been proposed. For example, there is a Mayday system that asks for assistance at the center outside the vehicle when detecting that the vehicle has entered an abnormal state such as an accident with a device provided on the vehicle side. If the in-vehicle device itself or the transmitter for center transmission breaks down, there is a problem that a rescue signal cannot be transmitted to the center.

  In order to solve this problem, although different from the Mayday system, in Patent Document 1 below, when the vehicle user leaves the vehicle, the vehicle position information is transmitted to the monitoring center at a predetermined interval. A theft reporting device that determines that a vehicle has been stolen when information cannot be received for a predetermined time or longer on the center side is disclosed.

  However, this technology has a problem in that the vehicle position information must be transmitted to the monitoring center at all times during parking since the theft has not occurred, only for the purpose of theft detection. is there.

  Conventionally, in order to diagnose a vehicle failure, for example, a vehicle diagnosis system shown in FIG. 11 has been constructed. The diagnosis system includes a vehicle 1A, a diagnosis center 2A, a call center 3, and a vehicle sales store 4. Normally, when an abnormality of an in-vehicle component mounted on the vehicle 1A is detected, the vehicle 1A transmits a code indicating the abnormality to the diagnosis center 2A (h). The diagnosis center 2A diagnoses the abnormality of the vehicle 1A based on the received code and notifies the user of the vehicle 1A of the content of the abnormality (i). The user of the vehicle 1A notified of the abnormality requests the call center 3 to execute the abnormality countermeasure by telephone communication (j). Upon receiving the request, the call center 3 requests a warning diagnosis from the diagnosis center 2A (k), and when receiving a warning diagnosis result from the diagnosis center 2A (l), presents emergency measures to the user of the vehicle 1A by telephone ( m).

On the other hand, when the call center 3 requests the vehicle dealer 4 to handle the abnormality of the vehicle 1A (n), and when the warning diagnosis of the vehicle 1A is transmitted from the diagnosis center 2A to the vehicle dealer 4 (o) (o) ), The vehicle dealer 4 requests the diagnosis center 2A to issue a warehousing guide for the vehicle 1A (p). When the user of the vehicle 1A receives the warehousing guidance from the diagnostic center 2A (q), the user of the vehicle 1A can enter the vehicle 1A (r).
