APPARATUS FOR CONTROLLING ACCESS OF VEHICLE DIAGNOSTIC DEVICE AND METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17811842 titled 'APPARATUS FOR CONTROLLING ACCESS OF VEHICLE DIAGNOSTIC DEVICE AND METHOD THEREOF
Simplified Explanation
The disclosed patent application describes an apparatus and method for controlling access to a vehicle diagnostic device. The apparatus includes a communicator for communication with the diagnostic device, a connector for connecting to the vehicle's electronic control unit (ECU), and a controller for performing authentication and transmitting messages.
- The apparatus includes a communicator for communication with a vehicle diagnostic device.
- It also includes a connector for connecting to the vehicle's electronic control unit (ECU).
- The controller performs primary authentication of the diagnostic device when it requests a diagnosis from the ECU.
- If the primary authentication fails, the controller transmits a first response ID and a first failure message to the diagnostic device.
- If the primary authentication is successful, the controller forwards the first response ID and a second failure message from the ECU to the diagnostic device.
Potential applications of this technology:
- Vehicle diagnostics and maintenance: The apparatus can be used in automotive workshops or by vehicle owners to diagnose and troubleshoot issues with their vehicles.
- Vehicle security: The authentication process helps ensure that only authorized diagnostic devices can access the vehicle's ECU, preventing unauthorized access and potential tampering.
Problems solved by this technology:
- Unauthorized access: The apparatus provides a means to authenticate and control access to the vehicle's ECU, preventing unauthorized devices from accessing sensitive information or potentially causing harm to the vehicle.
- Diagnostic device compatibility: By providing a standardized communication interface and authentication process, the apparatus ensures that only compatible diagnostic devices can communicate with the vehicle's ECU.
Benefits of this technology:
- Enhanced security: The authentication process adds an extra layer of security, protecting the vehicle's ECU from unauthorized access and potential malicious activities.
- Efficient diagnostics: By providing a standardized communication interface, the apparatus allows for efficient and accurate diagnostics, enabling quicker identification and resolution of vehicle issues.
Original Abstract Submitted
Disclosed is an apparatus for controlling access of a vehicle diagnostic device and a method thereof, in which the apparatus includes a communicator that provides a communication interface with the vehicle diagnostic device, a connector that provides a connection interface with an electronic control unit (ECU) in a vehicle, and a controller that performs primary authentication of the vehicle diagnostic device when the vehicle diagnostic device requests a diagnosis from the ECU, transmits a first response ID and a first failure message to the vehicle diagnostic device when the primary authentication fails, and forwards the first response ID and a second failure message from the ECU to the vehicle diagnostic device when the primary authentication is successful.
