METHOD FOR AUTHORISING ACCESS TO A MOTOR VEHICLE BY MEANS OF A MOBILE ELECTRONIC IDENTIFICATION TRANSMITTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18578832 titled 'METHOD FOR AUTHORISING ACCESS TO A MOTOR VEHICLE BY MEANS OF A MOBILE ELECTRONIC IDENTIFICATION TRANSMITTER

Simplified Explanation

The method described in the patent application involves authorizing access to a motor vehicle by monitoring the signal strength of a communication connection between the vehicle and an identification transmitter. When the transmitter moves away from the vehicle, the signal strength decreases, and access is authorized when the signal strength exceeds a reference value upon the transmitter's return.

  • Monitoring signal strength of communication connections
  • Deactivating and reactivating communication connections based on signal strength
  • Authorizing access to a motor vehicle based on signal strength changes

Key Features and Innovation

  • Monitoring signal strength of communication connections to authorize access
  • Storing reference value for signal strength when connection is deactivated
  • Reactivating connection when signal strength exceeds reference value

Potential Applications

This technology can be applied in the automotive industry for secure access control to vehicles. It can also be utilized in smart home systems for keyless entry.

Problems Solved

This technology addresses the issue of unauthorized access to motor vehicles by implementing a secure and efficient authorization process based on signal strength monitoring.

Benefits

  • Enhanced security for motor vehicles
  • Convenient keyless access control
  • Efficient authorization process

Commercial Applications

  • Automotive industry for vehicle access control systems
  • Smart home systems for secure keyless entry solutions

Questions about the Technology

How does this technology improve security in access control systems?

This technology enhances security by monitoring signal strength changes to authorize access only when the identification transmitter is in close proximity to the vehicle.

What are the potential drawbacks of using signal strength for access authorization?

One potential drawback could be signal interference or fluctuations that may affect the accuracy of the authorization process.


Original Abstract Submitted

A method for authorizing access to a motor vehicle involves monitoring a decrease in the signal strength of the second communication connection, while the identification transmitter is moved away from the motor vehicle, such that the spacing between the motor vehicle and the identification transmitter increase. The current signal strength of the second communication connection is stored as a reference value as soon as the first communication connection between the motor vehicle and the identification transmitter is deactivated/interrupted. The first communication connection is reactivated as soon as the signal strength of the second communication connection exceeds the stored reference value due to the decreasing spacing between the motor vehicle and identification transmitter when the identification transmitter is moved towards the motor vehicle again.
