Vehicle diagnostic system and method

The patent text describes a system for diagnosing and repairing vehicles that includes a diagnostic vehicle system with an electronic controller for executing algorithms to collect data related to the vehicle's diagnostic operations. The system also has an interface in communication with the diagnostic vehicle system and the vehicle's electronic controller. The electronic controller provides access to the data generated by the algorithms through an application programming interface (API) for user access. The system may also include a client device operated by the user for selective communication with the interface and a user application operating on the client device for access to data generated by the algorithms. The technical effects of the patent text are improved efficiency and accuracy in diagnosing and repairing vehicles by providing a user-friendly interface to data collected by the vehicle's electronic controllers and restricting access to the algorithms that generated the data related to the diagnostic operations of the vehicle.

This shift was necessary because the complexity of the user interface and amount of vehicle diagnostic data was exceeding the limitations of the bespoke handheld systems.

As these PC systems grow to support more advanced vehicles, they are becoming increasingly complex and difficult for car companies to manage and develop.

A single vendor is typically hired to develop the entire diagnostic system because no one has ever developed a way separate out the components of the system into pieces.

The single-vendor nature of the business has created several issues for car companies and end users.

The diagnostic system is limited to the resources and technical capabilities of that vendor.

If the car company is not happy with the relationship and wishes to terminate with that vendor, they have to discard the entire diagnostic system and start fresh with a new vendor in a process that typically takes more than a year.

The problem with third party diagnostic systems is that they do not always have complete and correct diagnostic information for vehicles.

This is because the third party systems license the data from car companies but often get out of date or incorrect information.

There is no way for third party companies to access the authored data already in the diagnostic system in real time so they must purchase a database or series of files that contain the diagnostic information for each year / make / model of car and then input that into the third party system.

There can be transcription errors, and often times the car company will update their own diagnostic information but those updates do not make it into the third party system.

It can also take many months for third party systems to get access to this information, author it into their own system, test it, and release it.

1. The current model forces the car company to use a single vendor for all aspects of their diagnostic system. If the vendor is not expert in all areas, the car company may be forced to compromise on features, cost, or performance.

2. If the car company is unhappy with the vendor's performance and wants to switch or develop things in-house, they often have to throw away the entire system and create a new system.

3. If the car company wants to expand their system to different platforms (such as mobile phones or tablets), they must pay their existing vendor to expand the system and new versions. Sometimes vendors may be unwilling or unable to expand their system to new platforms.

4. The way car companies license their diagnostic information to third parties is inefficient, expensive to maintain, and prone to introducing errors into third party applications.

5. In the current model, car companies are forced to license their diagnostic data that contains secret algorithms and other intellectual property to scantool companies with no built-in protection for that IP.
