Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault diagnosis voice guidance system and a fault diagnosis voice guidance method for receiving a push button signal from a portable terminal and returning a voice signal.

[0002]

2. Description of the Related Art Conventionally, as a failure diagnosis system of this type, for example, when a vehicle breaks down, a vehicle is brought to a maintenance shop, a failure diagnosis is performed by an existing system, and an estimated amount calculated based on the diagnosis is presented. is there. That is, in the vehicle failure diagnosis and the estimated vehicle repair amount, the judgment was made by the repair worker or the person in charge of the maintenance shop.

At that time, in order to calculate an estimate, an operator or a person in charge looks at a defective vehicle at the location of the vehicle or at a repair shop, and lists the damaged parts on an estimate sheet or an inspection sheet on which the estimate sheet is based. However, cost data such as part prices and wages are determined and described for the listed parts, and the cost for repairing the vehicle is calculated and estimated from these cost data.

For example, in the case of repairing an engine trouble and requiring engine replacement at a maintenance shop, a person in charge diagnoses a failed vehicle brought into the maintenance shop. As a result, the engine is diagnosed as having a failure. Then, an estimate is made by calculating the price of the engine to be replaced and the labor cost as the engine replacement work cost according to the judgment of the person in charge. After that, a quotation was prepared based on the quotation data, and the quotation amount was presented to the customer.

In addition, recently, by using a network such as the Internet, a predetermined terminal of a vehicle is accessed from a web terminal such as a personal computer (personal computer) to access a predetermined web server of the maintenance factory to input a vehicle failure status. There is also a diagnostic system that can search for a failure location and a rough estimate before the repair.

[0006]

However, in the case of the above-mentioned prior art, the following problems have occurred. That is, in the failure diagnosis and the estimation of the estimated amount by the repair worker or the person in charge of the maintenance shop, the broken vehicle is brought to the maintenance shop, or the worker goes to the location of the broken vehicle, and then the worker or the person in charge of the existing system. Since the failure diagnosis is performed and the estimated price is presented, it takes time for the customer to grasp the failure location and the estimated price. Further, in the conventional failure diagnosis system, it is largely determined by the operator or the person in charge, so that the determination varies depending on the experience and skill of the person who makes the determination, and the certainty is lacking.

Further, when confirming the estimated amount in advance before the repair work, it is largely determined by the operator or the person in charge. Therefore, in the conventional vehicle repair estimate, the estimated amount is determined by the experience and skill of the estimater. Difference occurs,
There was a problem that there was variation and the reliability was poor.

On the other hand, in the diagnosis system using a personal computer or the like, it is possible to retrieve the failure location and the rough estimate in advance, but the accident or failure of the vehicle is sudden, and it is necessary to do so. It's hard to imagine a situation where you have a computer. Therefore, it was difficult for the customer to quickly grasp the location of the breakdown and the estimated amount from the location of the breakdown vehicle.

The present invention has been made in view of the above matters, and in the event of an unexpected accident or breakdown, a simple operation using a telephone can be used to quickly diagnose a faulty portion of a vehicle and grasp an estimated amount of money. An object is to provide a failure diagnosis voice guidance system and a failure diagnosis voice guidance method that can be reliably performed.

[0010]

In order to solve the above problems, the present invention has the following means.

That is, in a failure diagnosis voice guidance system that receives a push button signal from a mobile terminal and sends back a voice signal, a call from the mobile terminal is accepted and the push button signal from the mobile terminal in the communication state is recognized. Use a failure diagnosis server that searches the database for a failure location corresponding to the recognized push button signal, calculates the repair cost required for the failure location, converts the failure location and the repair cost into voice information, and transmits the audio information to the mobile terminal. The failure guidance voice guidance method was used.

With the push button signal pressed by the portable terminal, the failure diagnosis voice guidance system can promptly and surely determine the failure location and present the estimated amount corresponding thereto. In addition, since the user can easily check the quotation, the customer can be encouraged to visit the store as a result. In addition, the failure diagnosis voice guidance system can automatically estimate the cost, which leads to a reduction in personnel costs at the maintenance shop.
