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 connection with the electronic control unit (ECU) in a vehicle, 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 electronic control unit (ECU) in a vehicle.
  • 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: The apparatus can be used in automotive workshops or service centers to control access to diagnostic devices and ensure secure communication with the vehicle's ECU.
  • Vehicle maintenance: By controlling access to diagnostic devices, the apparatus can help prevent unauthorized access and potential tampering with the vehicle's ECU during maintenance or repair operations.

Problems solved by this technology:

  • Unauthorized access: The apparatus provides a mechanism for authenticating diagnostic devices, preventing unauthorized access to the vehicle's ECU.
  • Secure communication: By performing authentication and transmitting messages, the apparatus ensures secure communication between the diagnostic device and the ECU.

Benefits of this technology:

  • Enhanced security: The apparatus improves the security of vehicle diagnostics by controlling access and preventing unauthorized tampering with the ECU.
  • Efficient diagnostics: By providing a secure communication interface, the apparatus enables efficient and accurate diagnostics of vehicle issues, leading to faster repairs and reduced downtime.


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.
