What is JVCI

Drew Technologies has developed JVCI, a software API and data Library, to get data off the in-vehicle network and deliver it to 3^rd party developers in a simple and easy-to-use format. JVCI works with the CarDAQ-Plus and CarDAQ-DV sold by Drew Technologies. JVCI automatically detects the protocols in use on the vehicle, determines what parameters are available for data acquisition, and delivers the data thru the API in a scaled format.

How Does it Work

The JVCI library encapsulates all of the different protocols with a simple software interface. The typical steps are:

1.        JVCI identifies the vehicle automatically, or prompts the user to select make/model/year manually

2.        JVCI automatically connects and sends the commands to enter the controller’s diagnostic mode

3.        JVCI queries the database for a list of supported enhanced parameters.

4.        The user is prompted to choose any number of parameters from a supported list. Each parameter will get a separate buffer for scaled, time stamped data.

Supported JVCI parameters

JVCI supports generic OBD on any vehicle 1996 or newer. Enhanced parameters are currently available for Ford Motor Company SCP/CAN vehicles and General Motors GMLAN vehicles. Planned future releases will extend enhanced parameter support to GM Class2, Chrysler, Toyota, Nissan, Honda, Mercedes, Subaru, and Mitsubishi.

Implementing JVCI

The library is provided as a C DLL with an integrated database of enhanced parameters.  JVCI requires experience with C programming, or using a C DLL in some other language. It’s designed for a programmer that does not want to program the CarDAQ directly, does not need to learn how to talk to an ECU, or cannot build a database of parameters.

JVCI may also work with C#, VB, LabVIEW, Java, and other programming languages. Consult with Drew Technologies for more information. It will work on Windows, Linux, OSX, and other standardized platforms.
