Abstract
A vehicle key-less entry system and a method of unlocking a vehicle door can detect whether or not a vehicle door handle is operated and an operational speed when the door handle is detected by entering a cipher code. Check is made whether the entered cipher code is equal to a prestored cipher code based on the detected operational speed. A locking mechanism is controlled to unlock a vehicle door when the entered cipher code is equal to the prestored cipher code.
Claims14
A vehicle key-less entry system, comprising:
- door-handle operation detecting means for detecting whether or not a vehicle door handle is operated and an operational mode by detecting a speed of the door handle, for entering a cipher code;
- checking means for checking whether the entered cipher code is equal to a prestored cipher code based on the detected operational mode;
- and
- locking controlling means for controlling a locking mechanism to unlock a vehicle door when the entered cipher code is equal to the prestored cipher code,
- wherein the door-handle operation detecting means detects the speed of the door handle based on at least two operational speed patterns.

A method of unlocking a vehicle door, comprising the steps of:
- detecting whether or not a vehicle door handle is operated and at least two operational speed patterns when the door handle is detected as operated for entering a cipher code;
- checking whether the entered cipher code is equal to a prestored cipher code based on the detected operational speed;
- and
- controlling a locking mechanism to unlock a vehicle door when the entered cipher code is equal to the prestored cipher code.
