Patent Images
1. An entry control system comprising:
- a transmitter for transmitting a transmission request signal in a predetermined area;
a receiver for receiving a response signal transmitted from a portable device in response to the transmission request signal, the response signal including identification information specific to the portable device;
a smart identification means for performing a smart identification to determine whether received identification information agrees with registered identification information;
a biometrics detection means for detecting biometric information;
a biometric identification means for performing a biometric identification to determine whether detected biometric information agrees with registered biometric information; and
a control means for causing one of two identification means to perform an identification thereof in a predetermined identification condition, for causing the other of two identification means to perform an identification thereof when an identification by the one of the two identification means is successful, and for allowing an entry of a user when the other of two identification means is successful.

Abstract
An entry control system for a vehicle has a transmitter for transmitting a transmission request signal, a receiver for receiving a response signal including an ID code from a portable device, and a biometrics sensor for detecting a face image of a user. The system compares the face image provided by the biometrics sensor with registered face image. If these images agree, the system then activates the transmitter and compares the ID code received from the portable device with a registered ID code. If these codes also agree, the system allows the user to open a door and start an engine of the vehicle.

11. An entry control system comprising:
-
a transmitter for transmitting a transmission request signal in a predetermined area;
a receiver for receiving a response signal transmitted from a portable device in response to the transmission request signal, the response signal including identification information specific to the portable device;
a smart identification means for performing a smart identification to determine whether received identification information agrees with registered identification information;
a trigger switch provided on a door;
a biometrics detection means for detecting biometric information;
a biometric identification means for performing a biometric identification to determine whether detected biometric information agrees with registered biometric information; and
a control means for controlling an operation of the smart identification means and the biometric identification means, wherein the control means causes, when the receiver receives the response signal, the smart identification means to perform the smart identification with a first high threshold level, subsequently causes the biometric identification with a second low threshold level, and allows an entry through the door if both of the identification means output positive identification results, and wherein the control means causes, when the trigger switch is operated, the biometrics identification means to perform the biometric identification with a second high threshold level higher than the second low threshold level, subsequently causes the smart identification means to perform the smart identification with a first low threshold level lower than the first high threshold level, and allows an engine starting if both of the identification means output positive identification results.

12. An entry control method for a vehicle having a transmitter for transmitting a transmission request signal in a predetermined area, a receiver for receiving a response signal transmitted from a portable device in response to the transmission request signal, the response signal including identification information specific to the portable device, and a biometrics sensor for detecting biometric information, the method comprising:
-
performing a first identification to determine whether received identification information agrees with registered identification information;
performing a second identification to determine whether detected biometric information agrees with registered biometric information; and
allowing an entry of a user only when both identifications are successful. - View Dependent Claims (13, 14)
